Optic disc coloboma - A hidden masquerader

Optic disc coloboma is a condition, present unilaterally or bilaterally, within the spectrum of optic nerve coloboma, characterized by a bowl-shaped excavation of the optic disc. The image depicts type 2 optic disc coloboma, as per Ida Mann’s classification, detected incidentally during routine ophthalmic screening in a patient with 20/20 vision⁽¹⁾. Despite its asymptomatic presentation, it is important not to overlook optic nerve coloboma, as it may be associated with macular schisis or retinal detachment⁽²⁾.
