Abstract

Objetivo: Comparar as alterações nos parâmetros do segmento anterior após a cirurgia ExPRESS Mini Glaucoma Shunt vs. trabeculectomia usando a câmera Scheimpflug Pentacam rotativa.
Métodos: Neste estudo comparativo prospectivo, 27 pacientes com glaucoma tratados no Centro Médico Rabin de 2009 a 2013 foram incluídos neste estudo comparativo prospectivo: 19 participantes (19 olhos) foram submetidos ao implante de derivação ExPRESS e 12 (13 olhos) foram submetidos à trabeculectomia. Alterações nos parâmetros da câmara anterior no dia 1 e em 3 meses de pós-operatório foram avaliadas pelas imagens de Scheimpflug.
Resultados: A pressão intraocular diminuiu significativamente em relação aos valores iniciais nos dois grupos. A diminuição nos dois grupos foi semelhante no 3º mês pós-operatório (p=0,82). A cirurgia com ExPRESS causou um aumento temporário do astigmatismo posterior da córnea (p=0,008) e uma diminuição temporária da profundidade da câmara anterior (p=0,016) e do volume (p=0,006) no primeiro dia do pós-operatório. Ao final de três meses, esses parâmetros não foram mais estatisticamente significativos (p=0,065, p=0,51 e p=0,57, respectivamente). A trabeculectomia causou um aumento temporário do astigmatismo anterior e posterior da córnea no primeiro dia do pós-operatório (p=0,003 e p=0,005, respectivamente), mas isso não foi observado ao final de 3 meses (p=1,0 e p=1,0, respectivamente). Após 3 meses, tanto o EXPRESS quanto a trabeculectomia mostraram alterações semelhantes nos parâmetros da câmara anterior.
Conclusões: O implante ExPRESS Mini para glaucoma e a trabeculectomia diminuíram significativamente a pressão intraocular e tiveram efeitos temporários nos parâmetros do segmento anterior, com pequenas diferenças entre os métodos.

Abstract

Objetivo: Comparar a viscotrabeculotomia com irrigação da câmara anterior com o implante de válvula de glaucoma de Ahmed para glaucoma secundário após remoção de óleo de silicone.
Métodos: Foi realizado um estudo prospectivo de 43 olhos pseudofácicos vitrectomizados com glaucoma persistente após a remoção de óleo de silicone. Os pacientes foram randomizados para viscotrabeculotomia com irrigação da câmara anterior ou implante de válvula de Ahmed. Todos os pacientes foram examinados no primeiro dia, na primeira semana e 1, 3, 6, 9, 12, 18 e 24 meses após a cirurgia. Observaram-se complicações pós-operatórias. O sucesso foi definido como uma pressão intraocular entre 6 e 20 mmHg e uma redução da pressão intraocular >30% em comparação com a pressão intraocular pré-operatória.
Resultados: Foram designados 22 olhos para o grupo da viscotrabeculotomia com irrigação da câmara anterior e 21 olhos para o grupo do implante de válvula de Ahmed. A pressão intraocular média pré-operatória foi de 35,5 ± 2,6 mmHg para o grupo da viscotrabeculotomia com irrigação da câmara anterior e pós- e de 35,5 ± 2,4 mmHg no grupo do implante de válvula de Ahmed. e Os valores pós-ope­ratórios foram de 16,9 ± 0,7 mmHg e 17,9 ± 0,9 mmHg para esses mesmos grupos, respectivamente (p<0,0001). Ambos os grupos tiveram uma redução estatisticamente significativa da pressão intraocular em relação aos valores pré-operatórios (p<0,0001) em todos os momentos do acompanhamento. A taxa de sucesso não qualificado nos grupos da viscotrabeculotomia com irrigação da câmara anterior e do implante de válvula de Ahmed foi de 72,73% e 61,9%, respectivamente. A complicação mais comum foi o hifema, autolimitado e mínimo.
Conclusões: Tanto a viscotrabeculotomia com irrigação da câmara anterior quanto o implante de válvula de Ahmed são eficazes na redução da pressão intraocular no glaucoma após injeção de óleo de silicone, mas a viscotrabeculotomia com irrigação em câmara anterior proporcionou maior redução da pressão intraocular e maiores taxas de sucesso, com complicações mínimas.

Abstract

Objetivo: Apresentar nossos resultados de longo período de vitrectomia pars plana combinada com fotocoagulação panretiniana com endolaser, implantação da válvula Ahmed para glaucoma e/ou facoemulsificação em pacientes com glaucoma neovascular complicado. Métodos: Foram incluídos no estudo 15 olhos de 15 pacientes com glaucoma neovascular como complicação da retinopatia diabética e devido à oclusão isquêmica da veia central da retina. Todos os casos tiveram hemorragia vítrea. Além disso, 8 dos casos apresentaram diferentes graus de hifema. A injeção intravítrea de bevacizumabe foi administrada em todos os casos 3 dias antes da cirurgia. Facoemulsificação, vitrectomia pars plana e implantação da válvula Ahmed para glaucoma foram realizadas em 12 pacientes fáquicos. A vitrectomia pars plana e a implantação da válvula Ahmed para glaucoma foram realizadas em 3 pacientes pseudofáquicos. Complicações perioperatórias e pós-operatórias, valores de pressão intraocular e valores de melhor acuidade visual corrigida pré-operatório e pós-operatório foram registrados.
Resultados: O acompanhamento médio foi de 24,4 ± 14,56 meses. A média da pressão intraocular pré-operatória foi de 50,06 ± 7,6 mmHg. Em 1 dia, 7 dias e 1,3,6,12 meses, e última visita após cirurgia, a média da pressão intraocular foi de 11,06 ± 8,22, 12,66 ± 7,27, 13,8 ± 7,73, 18,64 ± 7,05, 19,28 ± 4,61, 16,28 ± 1,68 e 16,92 ± 2,12 mmHg, respectivamente (p=0,001 para cada visita de acompanhamento). A média da acuidade visual na última visita foi de 1,18 ± 0,42 logMar (p=0,001 para cada visita de acompanhamento). Vários graus de reações de hifema e fibrina foram registrados como complicações precoces pós-operatórias. Phthisis bulbi foi desenvolvido em um caso durante o acompanhamento. A cirurgia de revisão da válvula Ahmed para glaucoma foi necessária em 4 casos.
Conclusões: Os procedimentos cirúrgicos combinados que realizamos são seguros, eficazes e preferenciais, tanto em termos de controle da alta pressão intraocular quanto fornecimento de habilidades visuais razoáveis em pacientes com glaucoma neovascular complicado.

Abstract

OBJETIVO: Glaucoma é a principal causa de cegueira irreversível no mundo. O pico da pressão intraocular é um dos principais fatores de risco para progressão do glaucoma, e o controle pressórico ainda é o único tratamento efetivo para todas as formas de glaucoma. O objetivo principal deste estudo é comparar a redução basal e do pico da pressão intraocular, obtidas através do Teste de Sobrecarga Hídrica, entre os dois olhos dos mesmos pacientes utilizando latanoprosta 0,005% em um olho e submetidos à aplicação de trabeculoplastia a laser seletiva no olho contralateral.
MÉTODOS: Este é um estudo prospectivo, intervencionista, longitudinal e randomizado. Trinta pacientes consecutivos, glaucomatosos, com pressão intraocular controlada em uso de monoterapia com latanoprosta, foram recrutados de um único centro oftalmológico. Os olhos dos pacientes foram randomizados e um olho foi selecionado para tratamento com trabeculoplastia a laser seletiva e olho contralateral tratado com colírio de latanoprosta 0,005%. Foram avaliados a pressão intraocular basal e pico de pressão intraocular um mês (Teste de Sobrecarga Hídrica 2) e seis meses (Teste de Sobrecarga Hídrica 3) após tratamento.
RESULTADOS: Não houve diferença estatística entre a pressão intraocular pré washout entre os olhos randomizados para trabeculoplastia a laser seletiva e latanoprosta, 13,6 ± 2,1 e 13,3 ± 1,8 mmHg, respectivamente (p=0,182). Em relação à pressão intraocular basal, não houve diferença estatística entre os grupos, tanto no Teste de Sobrecarga Hídrica 2 (p=0,689) e Teste de Sobrecarga Hídrica 3 (p=0,06). Não houve diferença estatística em relação ao pico de pressão intraocular entre os grupos trabeculoplastia a laser seletiva e latanoprosta, no Teste de Sobrecarga Hídrica 2 (p=0,771) e Teste de Sobrecarga Hídrica 3 (p=0,774).
CONCLUSÕES: Em resumo, nosso estudo demonsrou que a eficácia da redução pressórica é similar entre latanoprosta e trabeculoplastia a laser seletiva, e pacientes glaucomatosos que estão com a pressão intraocular clinicamente controlados com latanoprosta e trocam de tratamento para trabeculoplastia a laser seletiva mantém sua pressão intraocular controlada.

Abstract

PURPOSE: The purpose of this study was to assess visual outcomes and patient satisfaction following cataract surgery involving the implantation of quad-loop intraocular lenses, including trifocal, bifocal, and toric variants.
METHODS: Information was obtained from both physical and electronic medical records of patients who underwent phacoemulsification cataract surgery with implantation of different intraocular lenses between January 1, 2022, and December 31, 2023. The study included individuals aged over 18 who received bilateral implantation of bifocal, trifocal, or monofocal toric intraocular lenses. Visual acuity was assessed at various postoperative time points using the logMAR scale. Quantitative variables were analyzed using mean and standard deviation.
RESULTS: A total of 92 eyes received premium intraocular lenses: 4 bifocal, 32 trifocal, 52 toric monofocal, and 4 trifocal toric lenses. The average preoperative corrected visual acuity was logMAR 0.478 ± 0.259. On the first postoperative day, the average uncorrected visual acuity was logMAR 0.301 ± 0.207. By day 30, 67.4% of eyes achieved uncorrected distance visual acuity of logMAR 0.2 or better. Patient satisfaction was high, with few reports of glare or halos.
CONCLUSION: Quad-loop intraocular lenses-including trifocal, bifocal, and toric models-demonstrated effective improvement in visual acuity and high levels of patient satisfaction. These lenses represent a suitable option for enhancing visual outcomes after cataract surgery. Additional studies with larger cohorts are recommended to confirm these results.

Abstract

PURPOSE: This study aimed to determine whether early-stage intraocular pressure can be modulated using a thermal face mask.
METHODS:In this prospective clinical study, healthy participants were randomized on a 1:1:1 allocation ratio to three mask groups: hypothermic (G1), normothermic (G2), and hyperthermic (G3). After randomization, 108 eyes from 108 participants were submitted to clinical evaluations, including measurement of initial intraocular pressure (T1). The thermal mask was then applied for 10 minutes, followed by a second evaluation of intraocular pressure (T2) and assessment of any side effects.
RESULTS:The hypothermic group (G1) showed a significant reduction in mean intraocular pressure between T1 (16.97 ± 2.59 mmHg) and T2 (14.97 ± 2.44 mmHg) (p<0.001). G2 showed no significant pressure difference between T1 (16.50 ± 2.55 mmHg) and T2 (17.00 ± 2.29 mmHg) (p=0.054). G3 showed a significant increase in pressure from T1 (16.53 ± 2.69 mmHg) to T2 (18.58 ± 2.95 mmHg) (p<0.001). At T1, there was no difference between the three study groups (p=0.823), but at T2, the mean values ​​of G3 were significantly higher than those of G1 and G2 (p<0.00).
CONCLUSION:Temperature was shown to significantly modify intraocular pressure. Thermal masks allow the application of temperature in a controlled, reproducible manner. Further studies are needed to assess the duration of these effects and whether they are reproducible in patients with pathologies that affect intraocular pressure.

Abstract

PURPOSE: Glaucoma is a chronic and progressive disease that requires long-term treatment and continuous monitoring. The Kahook Dual Blade, a device used to perform goniotomy in adults, is designed to improve intraocular pressure control in patients with glaucoma. This study aimed to evaluate the long-term efficacy and safety of kahook dual blade goniotomy in glaucoma patients undergoing cataract surgery over a 36-month follow-up.
METHODS: This was a retrospective case series including 56 eyes from 56 patients with mild-to-moderate primary open-angle glaucoma who underwent phacoemulsification combined with kahook dual blade goniotomy. Mean intraocular pressure values, number of preoperative and postoperative hypotensive eye drops, procedure survival, and complications were evaluated over 36 months. Surgical success was defined as either a reduction in intraocular pressure of ≥20% with intraocular pressure between 6 and 18 mmHg without additional medication or a reduction of ≥1 eye drop with intraocular pressure between 6 and 18 mmHg.
RESULTS: The mean preoperative intraocular pressure decreased from 15.96 ± 2,83) mmHg to 13.14 ± 2,11) mmHg at 36 months, representing a 14.9% reduction (p<0.001). The mean number of eye drops decreased from 1.91 ± 0,75) to 1.34 ± 0,92), a 29.8% reduction (p<0.001). The overall success rate was 69.6% at 36 months.
CONCLUSION: Kahook dual blade goniotomy combined with cataract surgery significantly reduced intraocular pressure and the number of hypotensive eye drops required in patients with mild-to-moderate primary open-angle glaucoma, with a favorable success rate maintained at 36 months.

Abstract

PURPOSE: This study aimed to report the surgical outcomes and success predictors of micropulse transscleral cyclophotocoagulation in eyes with refractory glaucoma.
METHODS: This was a noncomparative, interventional case series. Patients with refractory glaucomas, defined as eyes with prior incisional glaucoma surgery failure and uncontrolled intraocular pressure, who underwent micropulse transscleral cyclophotocoagulation between March 2017 and June 2021 were enrolled. A minimum follow-up period of 6 months was required. Preoperative and postoperative intraocular pressure, number of hypotensive medications, surgical complications, and any subsequent related events were recorded. Success criteria were as follows: 1) intraocular pressure reduction ≥20% and intraocular pressure ≤18 mmHg; 2) intraocular pressure reduction ≥30% and intraocular pressure ≤15 mmHg. The need for topical hypotensive medications was not considered a failure.
RESULTS: Seventy-nine (79) eyes (79 patients; mean age, 57.5 ± 20.6 years) were included. Overall, the median follow-up duration was 12.0 (interquartile interval, 6–24) months, and the mean intraocular pressure was reduced from 22.8 ± 6.8 mmHg to 15.5 ± 5.6 mmHg at the last follow-up visit (p<0.001). The mean number of medications was reduced from 2.8 ± 0.7 to 2.0 ± 1.0 (p<0.01). At 12 months postoperatively, the success rates for criteria 1 and 2 were 54.9% and 49.7%, respectively. Aside from one case of corneal ulcer, which fully resolved with clinical treatment, and two cases of persistent hypotony (with no visual acuity loss during follow-up), no other vision-threatening complications were observed during the postoperative period. The magnitude of intraocular pressure reduction at 1 month (adjusted to preoperative intraocular pressure; HR=1.01; p=0.002).
CONCLUSION: Our findings suggest that micropulse transscleral cyclophotocoagulation is a relatively effective alternative for managing refractory glaucomas, with minor postoperative complications. In addition, the initial intraocular pressure reduction was a statistically significant predictor of 1-year success in patients undergoing micropulse transscleral cyclophotocoagulation.

Abstract

PURPOSE: This study aimed to evaluate the influence of intrastromal corneal ring segment implants on the intraocular pressure measurements using Goldmann applanation tonometry, rebound tonometry, and noncontact tonometry in keratoconic corneas and analyze the intertonometer agreement.
METHODS: We enrolled 74 eyes in this observational and prospective study. Each participant had a complete eye examination, corneal analysis with Scheimpflug Tomography (Pentacam^®), and intraocular pressure evaluation with Goldmann applanation tonometry, rebound tonometry, and noncontact tonometry, before and after intrastromal corneal ring segment implantation (on postoperative days 1, 7, 45, and 90). Intertonometer agreement was assessed using Bland-Altman analysis.
RESULTS: The mean age was 29.9 ± 10.2 years, and 47 (63.5%) eyes had keratoconus grade II. Intraocular pressures were higher for noncontact tonometry preoperatively and on 90 postoperative day (mean ± SD: 12.4 ± and 12.1 ± 2.2 mmHg, respectively), followed by Goldmann applanation tonometry (11.1 ± 3.0 and 11.2 ± 2.7 mmHg, respectively), and were lower for rebound tonometry (9.7 ± and 9.4 ± 3.2 mmHg, respectively). The variation from the Goldmann tonometry on 7 postoperative day to the baseline (p=0.022) and that of noncontact tonometry on 90 postoperative day to the baseline (p=0.021) were statistically significant. The rebound tonometry underestimated intraocular pressure when compared with the Goldmann applanation tonometry by a mean of 1.47 ± 5.19 mmHg. Noncontact tonometry, when compared with Goldmann applanation tonometry, overesti-mated intraocular pressure by a mean of 1.23 ± 4.15 mmHg.
CONCLUSION: Despite statistically significant differences between some postoperative periods, the intraocular pressure measurement differences may not be clinically relevant.

Abstract

PURPOSE: To quantitatively compare eyebrow and eyelid positions in anophthalmic sockets reconstructed with conical or spherical orbital implants combined with customized external ocular prostheses.
METHODS: This cross-sectional observational study included 38 patients with unilateral anophthalmic sockets, of whom 21 received conical implants, and 17 received spherical implants. Eyelid and eyebrow parameters—including margin reflex distance 1 and 2, vertical and horizontal palpebral fissure dimensions, eyebrow-to-upper-eyelid margin distance in primary gaze and infraduction, medial and lateral eyelid angles in primary gaze, and superior eyelid sulcus depth —were quantitatively assessed using standardized digital photographs analyzed with Image J software. The contralateral healthy eye served as the control. Statistical analyses were performed to compare measurements between groups.
RESULTS: In the primary gaze position, conical and spherical implants showed comparable margin-reflex distance1, margin-reflex distance2, vertical palpebral fissure height, eyelid margin position, and medial and lateral eyelid angles. During infraduction, the upper eyelid margin was significantly lower in sockets reconstructed with conical implants. Compared with contralateral normal eyes, anophthalmic sockets exhibited a reduced horizontal palpebral fissure and a deeper superior eyelid sulcus, irrespective of implant shape.
CONCLUSION: Anophthalmic sockets reconstructed with conical or spherical implants demonstrate similar eyebrow and eyelid positioning in primary gaze. However, conical implants are associated with a lower eyelid margin during infraduction. Independent of implant format, anophthalmic sockets show a narrower horizontal palpebral fissure and increased superior sulcus depth compared with normal eyes.

Abstract

PURPOSE: This study aims to compare the initial ocular discomfort symptoms resulting from trabeculectomy and Ahmed glaucoma valve implantation surgeries.

METHODS: A prospective comparative study was conducted. The evaluation of ocular discomfort employed a questionnaire designed to identify the frequency and severity of distinct symptoms: ocular pain, general discomfort, tearing, foreign body sensation, and burning. This questionnaire was administered prior to surgery as a baseline, and subsequently at 7, 30, and 90 days post-surgery. Simultaneously, the Ocular Surface Disease Index (OSDI) was applied at these same time intervals.
RESULTS: The study encompassed a total of 17 patients (9 undergoing trabeculectomy and 8 undergoing Ahmed glaucoma valve implantation). The Ahmed glaucoma valve implantation group exhibited higher tearing levels at baseline (p=0.038). However, no statistically significant differences in symptoms were observed between the two surgeries at 7 and 30 days post-surgery. At the 90-day mark following surgery, patients who had undergone trabeculectomy reported a significantly higher foreign body sensation (p=0.004). Although OSDI scores did not differ between groups at baseline, the trabeculectomy group showed significantly higher OSDI scores than the Ahmed glaucoma valve implantation group at 7, 30, and 90 days after surgery (p<0.05).
CONCLUSION: Post-surgery, patients who had undergone trabeculectomy experienced increased foreign body sensation. Trabeculectomy appears to cause greater early postoperative ocular discomfort compared to the Ahmed glaucoma valve implantation group.

Abstract

PURPOSE: As superotemporal implantation of the Ahmed glaucoma valve is not always feasible in cases of refractory glaucoma, this study examined the characteristics and surgical outcomes of cases in which the valve was implanted in a nonsuperotemporal quadrant using a modified long scleral tunnel technique.
METHODS: This retrospective case-control study included 37 eyes with nonsuperotemporal quadrant-Ahmed glaucoma valve implantation in Group 1 and 69 eyes with superotemporal Ahmed glaucoma valve implantation in Group 2. The demographic characteristics of these groups, surgical outcomes, including complications, further surgical interventions, and surgical success rates were compared. Surgical success was defined as an intraocular pressure not exceeding 21 mmHg, accompanied by a minimum reduction of 20% in intraocular pressure from the baseline without any additional intraocular pressure-lowering procedures, and the absence of light perception loss or phthisis bulbi.
RESULTS: Group 1 had significantly higher numbers of eyes with secondary glaucoma and preoperative surgical procedures than Group 2 (p<0.05). Both groups had mean preoperative intraocular pressure values, and mean intraocular pressure values at the last visit of 34.2 and 27.9 months, 35.5 ± 1.5 and 35.8 ± 1.2 mmHg, and 14.5 ± 5 and 14.9 mmHg, respectively. Although both groups had 70.2% and 75.8% as their five-year cumulative probability of success, respectively, the rates of complications, revisional surgery, and additional surgical procedures did not differ significantly (p>0.05).
CONCLUSION: The modified long scleral tunnel technique for Ahmed glaucoma valve implantation in nonsuperotemporal quadrants achieves intraocular pressure control and complication rates comparable to superotemporal implantation.

Abstract

Glaucoma is a progressive optic neuropathy that can cause irreversible blindness, though it rarely affects women of reproductive age. Its management during pregnancy and lactation is particularly challenging because of the potential impact of intraocular pressure fluctuations on disease progression and the risks of treatment to both the mother and fetus. Physiological changes in pregnancy, such as decreased intraocular pressure and hormonal alterations, may influence disease activity but do not guarantee disease stability. Preconception counseling plays a key role in mitigating risks and tailoring treatment strategies. Many glaucoma medications carry teratogenic risks, with brimonidine being the only US Food and Drug Administration Category B drug. Surgical interventions – including laser trabeculoplasty and minimally invasive glaucoma surgeries – offer alternative options but require careful timing and consideration of fetal safety. Multidisciplinary collaboration is essential to optimize maternal and neonatal outcomes. This review summarizes evidence-based approaches for glaucoma management during pregnancy and lactation, highlighting clinical considerations, therapeutic strategies, and patient-centered care.

Abstract

O implante de dispositivos de drenagem para glaucoma (DDGs) é uma opção terapêutica valiosa, principalmente em crianças com glaucoma refratário ao tratamento cirúrgico primário. Os dispositivos de drenagem para glaucoma têm sido utilizados principalmente quando a cicatrização conjuntival dificulta a cirurgia fistulizante ou procedimentos angulares prévios não foram eficazes no controle da pressão intraocular. Apesar das complicações conhecidas, o uso de dispositivos de drenagem para glaucoma em crianças tem aumentado nos últimos anos, inclusive como opção cirúrgica primária. Nesta revisão, atualizamos os resultados de estudos recentes envolvendo o implante de dispositivos de drenagem para glaucoma em crianças, discutindo novos avanços e comparando diferentes dispositivos, taxas de sucesso e complicações.

Abstract

Myopia is a significant risk factor for glaucoma and a growing public health problem worldwide. Detecting glaucomatous changes in highly myopic eyes is diagnostically challenging due to the abnormal appearance of the optic nerve head. These patients also have a greater biomechanical susceptibility to pressure-induced glaucomatous damage. Refractive surgery has become increasingly popular, and many candidates for refractive surgery are myopic. Therefore, we sought to review the aspects of patient evaluation in those who have undergone refractive surgery for myopia concerned with the detection and monitoring of glaucoma development. We identified several important elements of patient evaluation for glaucoma after refractive surgery. These included the need for both structural and functional assessments before and after surgery, and the importance of monitoring for postoperative biomechanical changes in the cornea and their impact on intraocular pressure. We conclude that, in patients who undergo refractive surgery for myopia, it is essential to assess for the presence of glaucoma, to identify staging, and to plan for long-term control of the disease, regardless of IOP.
