PURPOSE:Pigment epithelial detachment (PED) may be seen in all stages of age-related macular degeneration (ARMD) and may lead to poor prognosis. In this study, we retrospectively examined the effect of anti-VEGF treatments in ARMD patients with vascularized PED. METHODS:Medical records of 15 patients with PED secondary to ARMD were reviewed retrospectively. The diagnosis of PED was made with fundoscopy, fundus fluorescein angiography and optical coherence tomography. Patients were treated with intravitreal ranibizumab or/and bevacizumab and followed up for a minimum of one year. PED height and best corrected visual acuity (BCVA) was obtained before the first intravitreal anti-VEGF injection and again at the 1st, 3rd, 6th and 12th month after the injection. RESULTS: The mean baseline BCVA was 0.71 ± 0.48 logarithm of the minimal angle of resolution (logMAR) unit and the mean baseline PED height was 361 ± 153 µ. The mean injection count per eye was 3.9 ± 2.9. There was a significant reduce in mean PED height (247 ± 177 µ) also in 2 eyes PED completely resolved at the end of the follow up period. The mean BCVA at 12th month (0,69 ± 0,37) were not different from the baseline record. CONCLUSIONS: This retrospective case series showed that intravitreal anti-VEGF therapy preserved vision and reduced PED height in PED patients in a one-year follow-up period.

PURPOSE: To describe the clinical characteristics, management and treatment outcomes of patients with post-surgical suprachoroidal hemorrhage (SCH). METHODS: A retrospective cross-sectional study was conducted, in which the medical records of 9 consecutive patients with SCH admitted to the Goldschleger Eye Institute were reviewed. RESULTS: The mean age was 74 years (range 61-84) and the mean follow-up time was 38.3 ± 0.1 months (range 4-87 months). Four cases were associated with glaucoma surgeries (2 trabeculectomies and 2 Ahmed valve implantations), 3 cases with cataract surgery and 2 cases with pars plana vitrectomy. The diagnosis of SCH was ranging from intra-operative to 8 days following the primary procedure. Most patients underwent posterior sclerotomies and drainage alone or combined with pars plana vitrectomy in a mean timing of intervention of 11 ± 4 days. At one month of follow-up the visual acuity improved in 7 eyes and remained stable in 2, compared to the VA prior to the drainage operation. The mean VA improved from 2.03 to 1.285 logMAR units at 1 month following the drainage procedure (p=0.003). CONCLUSIONS: SCH still remains a challenging complication of many ophthalmological procedures. The current surgical management may improve visual acuity though the general prognosis is still poor.

PURPOSE: Evaluate contact lenses fitting after intracorneal ring implantation for keratoconus, its visual acuity and comfort. METHODS: Retrospective study of patients undergoing contact lenses fitting, after intracorneal ring for keratoconus. The criterion for contact lens fitting was unsatisfactory visual acuity with spectacle correction as referred by the patients. All patients were intolerants to contact lenses prior to intracorneal implantation. Visual acuity analysis was done by conversion of Snellen to logMAR scales. The comfort was evaluated according subjective questioning of good, medium or poor comfort. RESULTS: Nineteen patients were included in the study. Two patients (10.5%) did not achieved good comfort with contact lenses and underwent penetrating keratoplasties. All the others 17 patients showed good or medium comfort. Four rigid gas-permeable contact lenses were fitted, one piggyback approach, 3 toric soft contact lenses, 2 soft lenses specially design for keratoconus and 7 disposable soft lenses. The average visual acuity improved from 0.77 ± 0.37 to 0.19 ± 0.13 logMAR units after contact lenses fitting. CONCLUSION: Contact lens fitting after intracorneal ring is possible, provides good comfort, improves visual acuity, and therefore, may postpone the need for penetrating keratoplasty.

PURPOSE: The optical correction of presbyopia must be handled individually. Our aim was to compare the methods used in addition to the refractive near vision, with the final addition used in presbyopic patients. METHODS: Eighty healthy subjects with a mean age of 49.7 years (range 40 to 60 years) were studied. Tentative near additions were determined using four different techniques: one-half amplitude accommodation with minus lenses (AAL); one-third accommodative demand with positive lens (ADL); balanced range of accommodation with minus and positive lenses (BRA) and crossed cylinder test with initial myopisation (CCT). The power of the addition was then refined to arrive at the final addition. RESULTS: The mean tentative near additions were lower than the final addition for ADL and BRA addition methods. The mean differences between tentative and final additions were low for all the tests examined (less than 0.25 D). The intervals between the 95% limits of agreement differed substantially and were always higher than ±0.50 D. CONCLUSION: All the methods used displayed similar behavior and provided a tentative addition close to the final addition. The coefficient of agreements (COA) detected suggests that every tentative addition should be adjusted according to the particular needs of the patient.

PURPOSE: To examine the prevalence of ocular surface complaints in Brazilian patients with glaucoma or ocular hypertension who used topical intraocular pressure (IOP)-lowering regimens. METHODS: In this multicenter, noninterventional, single-visit study, adults with glaucoma or ocular hypertension treated with an IOP-lowering regimen were administered the 12-item ocular surface disease index (OSDI) questionnaire. Each response was scored on a 5-point scale, with 0 indicating symptom present none of the time and 4 indicating symptom present all of the time. The average of the 12 item responses for each patient was transformed to a scale from 0 to 100, with higher scores representing worse disabilities. OSDI results then were categorized as absence of OSD (scores of 0-12), mild OSD (scores of 13-22), moderate OSD (scores of 23-32), or severe OSD (scores of 33100). RESULTS: The 173 enrolled patients had a mean age of 61.2 years, were women in 65.3% of cases, and had glaucoma in 89.0% of cases and ocular hypertension in 11.0% of cases. OSDI scores for 158 patients using 1 IOP-lowering therapy indicated no OSD in 37.3% of patients (59/158), mild OSD in 20.9% (33/158), moderate OSD in 17.1% (27/158), and severe OSD in 24.7% (39/158). For the 120 patients using 1 IOP-lowering medication and having a known duration of diagnosis of glaucoma or ocular hypertension, mean OSDI scores were numerically higher (worse) for the 39 patients with a diagnosis ≥6 years long (score 25 [± 20], indicating moderate OSD) than for the 81 patients with a diagnosis lasting <6 years (score 22 [± 20], indicating mild OSD); however, no significant differences in OSDI scores by duration of diagnosis were evident in means (P=0.49), distributions (P≥0.26), or correlation (P=0.77). CONCLUSIONS: A large proportion of Brazilian patients treated with 1 IOP-lowering therapy had some ocular surface complaints.

PURPOSE: To relate the outcomes of 7 eyes of 7 patients in which a dexamethasone 0.7 mg implant (Ozurdex®) was placed inside the capsule bag after phacoemulsification and intraocular lens (IOL) implantation and compare with the fellow eyes, that were operated by the same technique and received dexamethasone eyedrops in the post-operatory. METHODS: Report review of 7 eyes of 7 patients who received dexamethasone 0.7 mg implant after phacoemulsification and IOL, comparing them to the fellow eyes. All the patients underwent bilateral cataract surgery, with one month interval, by the same technique and by experienced surgeons, without complications. Post operatory medication consisted of moxifloxacin eye drops for all the 14 eyes and topic dexamethasone for the 7 eyes that did not received the implant. RESULTS: Nuclear cataract classification (according to LOCS III) was 3.28 ± 0.69 in the implant eye group and 3.14 ± 0.83 in the fellow eye group. Postoperative best spectacle correct visual acuity (BSCVA) was 0.85 ± 0.12 and 0.87 ± 0.13, respectively in the implant and fellow eye groups. The intraocular pressure remained stable and similar to the pre-operative measurements. Anterior chamber reaction and cornea edema were similar in both groups in the follow-up. Two of the four no sutured pellet migrated to the anterior chamber during the first post-operative week and had to be repositioned. Another no sutured pellet dislocated and remained partially inside the capsule bag. The 3 patients with IOL haptic-sutured pellet had no complications. CONCLUSIONS: In the present study, dexamethasone 0.7mg implant were effective in controlling the inflammation after phacoemulsification and IOL implantation, with no significant side effects.

PURPOSE: To correlate parameters derived from corneal deformation resulting from non-contact tonometry integrated with an ultra-high-speed (UHS) Scheimpflug camera (Oculus Corvis ST, Scheimpflug Technology; Wetzlar, Germany) with age in normal eyes from young patients. METHODS: Observational, retrospective study involving one eye randomly selected from study participants, totaling 89 healthy eyes. The Scheimpflug images were taken with an ultra-high-speed camera during each measurement by the corvis ST. The deformation amplitude (DA) and other parameters (e.g., pachy apex, intraocular pressure, 1st A time, highest concavity-time, 2nd A time, 1st A Length, 2nd A Length, Wing-Dist, curvature radius highest concavity, curvature radius normal, Vin, Vout) measured by the corvis ST were correlated with age. The Kolmogorov-Smirnov test was applied, and Spearman's correlation test was utilized to evaluate the parameters measured by the Corvis ST and age. RESULTS: Mean patient age was 27.50 ± 6.30 years. The highest concavity-time was the only studied parameter statistically significantly correlated to age (i.e., p=0.04, rs=0.18). All other corvis parameters were not correlated to age. This included DA (p=0.319), intraocular pressure (p=0.854), pachy apex (p=0.066), 1st A time (p=0.959), 2nd A time (p=0.561), 1st Length (0.552), 2nd Length (p=0.697), Wing-Dist (p=0.769), curvature radius HC (p=0.145), curvature radius normal (p=0.513), Vin (p=0.980) and Vout (p=0.592). CONCLUSIONS: In healthy eyes, age and pressure or biomechanics as derived from the Corvis ST parameters were not associated with exception to highest concavity-time, i.e., the time from starting until the highest concavity is reached.

PURPOSES: Compare the visual acuity of patients who underwent cataract surgery by phacoemulsification with IOL AcrySof® toric implantation versus AcrySof® IQ and evaluate the reduction of cylindrical diopters (CD) in the postoperative period. METHODS: Analytical and retrospective study of 149 eyes with 1 or more diopters of regular symmetrical keratometric astigmatism, which underwent cataract surgery by phacoemulsification. The eyes were divided into two groups: the toric group with 85 eyes and the non-toric group with 64 eyes. In the pre-operative phase, topographic data and refraction of each eye to be operated were assessed. In the postoperative phase, refraction and visual acuity with and without correction were measured. RESULTS: The preoperative topographic astigmatism ranged from 1.00 to 5.6 DC in both groups. Average reduction of 1.37 CD (p<0.001) and 0.16 CD (p=0.057) was obtained for the toric and non-toric group when compared to the refractive astigmatism, respectively. Considering visual acuity without correction (NCVA), the toric group presented 44 eyes (51.7%) with NCVA of 0 logMAR (20/20) or 0.1 logMAR (20/25) and the toric group presented 7 eyes (10.93%) with these same NCVA values. DISCUSSION: The results show that patients with a significant keratometric astigmatism presented visual benefits with the toric IOL implantation. The reduction of the use of optical aids may be obtained provided aberrations of the human eye are corrected more accurately. Currently, phacoemulsification surgery has been used not only for functional improvement, but also as a refraction procedure.

PURPOSE: To assess the prevalence of refractive errors in Möbius sequence. METHODS: This study was carried out during the Annual Meeting of the Brazilian Möbius Society in November 2008. Forty-four patients diagnosed with the Möbius sequence were submitted to a comprehensive assessment, on the following specialties: ophthalmology, neurology, genetics, psychiatry, psychology and dentistry. Forty-three patients were cooperative and able to undertake the ophthalmological examination. Twenty-two (51.2 %) were male and 21 (48.8%) were female. The average age was 8.3 years (from 2 to 17 years). The visual acuity was evaluated using a retro-illuminated logMAR chart in cooperative patients. All children were submitted to exams on ocular motility, cyclopegic refraction, and fundus examination. RESULTS: From the total of 85 eyes, using the spherical equivalent, the major of the eyes (57.6%) were emmetropics (>-0.50 D and <+2.00 D). The prevalence of astigmatism greater than or equal to 0.75 D was 40%. CONCLUSION: The prevalence of refractive errors, by the spherical equivalent, was 42.4% in this studied group.

PURPOSE: To report the visual outcomes and complications of congenital cataract surgery with primary intraocular lens implantation in microphthalmic eyes of children younger than 4 years of age. METHODS:This retrospective interventional case series included 14 microphthalmic eyes from 10 children who underwent congenital cataract surgery with primary intraocular lens implantation younger than 4 years of age. Seven patients had bilateral cataracts (11 eyes met the study's inclusion criteria) and 3 patients had unilateral cataract. Patients' medical charts were reviewed to obtain information regarding the preoperative and postoperative ophthalmological examination. Main outcome measures were intraocular pressure (IOP), best-corrected visual acuity, and intraoperative and postoperative complications. RESULTS: Mean age at the time of surgery was 21.7 ± 2.9 months. Mean ocular axial length was 19.2 ± 0.9 mm. Mean preoperative IOP was 9.7 ± 1.7 mmHg and 10.3 ± 3.1 mmHg on final follow-up (P=0.18). There were no intraoperative complications. Two (15.4%) eyes developed secondary visual axis opacification, of which only one needed to be reoperated due to significantly decreased vision (0.5 logMAR). Preoperative and postoperative best-corrected visual acuity was 2.09 ± 0.97 logMAR and 0.38 ± 0.08 logMAR in bilateral cases and 1.83 ± 1.04 logMAR and 0.42 ± 0.13 logMAR in unilateral cases, respectively. CONCLUSION: Primary intraocular lens implantation in congenital cataract surgery in microphthalmic eyes resulted in a significant best-corrected visual acuity improvement with no intraoperative complications and minimal postoperative complications.

The purpose of this study is report a child with periorbital liposarcoma describing the clinical, epidemiological and therapeutic aspects. Six-months-old female baby with increasing tumor in the right fronto-zigomatic region wich was submitted to excision and the patologic and immunohistochemistry analisys observed typical findings of lipoblastoma. After that, there were three tumors relapse with the same diagnosis. One year after the last surgery there was a recurrence of the tumor but at this time the diagnosis was lipossarcoma and the patient was referred for additional treatment wilth radiotherapy and chemotherapy no new injuries so far Due to its rarity, liposarcoma usually does not enter the differencial diagnosis in the patients with orbital masses, however because of its local aggressiveess, it's vital the early identification and treatment to provide better therapeutic results and quality of life.

We describe the case of a 9-month old boy with unilateral retinoblastoma and bulftalmo. Primary enucleation was the treatment of choice due to the lack of visual prognosis. The histology of the enucleated eye showed massive choroidal invasion by the tumor and the optic nerve free of neoplastic tissue. Therefore, no adjuvant chemotherapy or radiotherapy was indicated. Three months after the enucleation, the patient returned with massive orbital retinoblastoma with exposure of the conjunctiva. Treated with chemotherapy, the patient has been in remission for 12 months. The risk factors for orbital recurrence are discussed.

The aim of this study is to report a clinical case of asymptomatic female Caucasian children with torpedo maculopathy. A 5-year-old girl was referred to our clinic for routine evaluation. The ophthalmic examination revealed best-corrected visual acuity of 20/20 in both eyes, without any changes in the biomicroscopy. Fundus examination showed normal findings in one eye, whereas in the contralateral eye it disclosed, in the temporal sector of the macular region, a whitish, atrophic, oval chorioretinal lesion with clearly defined margins. Posterior evaluations documented the stability of the lesion. Torpedo maculopathy diagnosis is based on its characteristic shape and peculiar location. The differential diagnosis has to be estabilished versus choroidal lesions (melanoma and nevus), congenital or iatrogenic hyperplasia of the retinal pigment epithelium (RPE) and particularly versus the congenital pigmented lesions associated with Gardner's syndrome.

Diffuse unilateral subacute neuroretinitis (DUSN) is a form of uveitis that can potentially lead to blindness. In Brazil and other parts of South America, diffuse unilateral subacute neuroretinitis is an important cause of posterior uveitis in children and healthy young adults. If diagnosed and treated in early stage, allows a resolution of symptoms with improvement of visual acuity. If the disease progresses to the late stage, can result in significant visual loss. In this study, through a literature review, we describe the main characteristics of this disease, including the following aspects: history, etiology, physiopathology, clinical features, diagnosis, differential diagnosis and treatment.
