Case Study
A 49 years old male patient admitted to hospital with difficulty in reading. Distant visual acuity, anterior segment examination, and intraocular pressure measurements were normal in his both eyes. The fundus examination was normal in his right eye but in the left eye a pigmented lesion overlying and surrounding the optic disk was detected. Visual field examination (HFA II version 740 Humphrey Instruments, Inc SanLeandro, CA, Central 30-2 Threshold Test) was unremarkable in his right eye but an enlarged blind spot was detected in his left eye. Optical coherence tomography (OCT) scans showed high reflectance layer with optical shadowing behind it. OCT is a useful device in describing the actual size of melanocytoma and its follow up. OCT has a role to find out associated subretinal fluid, cystoid retinal edema, retinal traction and epiretinal membrane. We are presenting this case to emphasize the OCT findings of melanocytoma.
