Purpose: To describe a rare case of Nevus of Ota with secondary Glaucoma in Ispahani Islamia Eye
Institute and Hospital (IIEH &H). A 5 years 7 months old boy came to this hospital for dimness of
vision in left eye. On examination, there was hyperpigmentation of both eyes and surrounding adnexa
(L/E > R/E). His BCVA was 6/6 in R/E and 6/24 in L/E.Colour vision was normal in B/E. Iris pigment
on anterior lens capsule B/E was found (L/E > R/E). IOP was 12mmHg in R/E and 16mmHg in L/E
with anti-glaucoma medication (Timolol and Dorzolamide combination). B-scan report showed axial
length and CRC thickness was normal in B/E. In CFP B/E fundus is hyperpigmented(L/E>R/E) and
C:D ratio is 0.5:1 in R/E and 0.85:1 in L/E. After adequate counselling, patient was advised for
Trabeculectomy with Mitomycin C under GA in L/E. We follow-up the patient for 1st , 7th and 1 month
after surgery.
Conclusion: Although bilateral Nevus of Ota is a rare disease, there is a 10% chance for developing
Glaucoma. Trabeculectomy with Mitomycin C can decrease the risk of progression of Glaucoma
