Abstract A 36 year old white male presented for routine eye examination with a history of poor vision and 'iris defect' since birth OD. Best corrected VA was light projection OD, with highly myopic refractive error (-14 D), and 20/20 OS, with low hyperopic refractive error (+0.75 D). The patient was unable to respond to confrontational visual field testing OD; OS visual field was full to finger counting. Pupil testing revealed absence of inferior iris tissue and postive afferent pupillary defect OD. Slit lamp biomicroscopy revealed iris coloboma and inferior punctate lenticular opacities OD, but was unremarkable OS. With dilated fundus examination, a tremendous coloboma involving ciliary body, retina, choroid, and optic disc was observed OD with obliteration of the macula. An inferotemporally located optic pit was observed OS without associated serous macular detachment. B-scan confirmed an approximately 4 mm deep excavation of the inferior posterior globe. The aforementioned findings were photo documented. Polycarbonate lenses were prescribed, and the patient was instructed on daily monitering of his left eye vision with Amsler grid. Symptoms of serous macular detachment were discussed. Coexistence of coloboma and optic pit contralaterally in this patient may be reflective of a common pathogenesis between these two congenital ocular conditions. Pathogenesis, differential diagnosis, systemic and ocular associations, and management will be discussed.
