Ophthalmologic manifestations of organoid nevus syndrome: A series of 13 cases.

Background: The organoid nevus syndrome is a rare neurocutaneous syndrome typified by cutaneous sebaceous nevus, seizures and epibulbar choristomas. The condition is associated with multiple ocular abnormalities. Herein, the authors aim to study and report the ophthalmic features of cases diagnosed with organoid nevus syndrome. Methods: The authors retrospectively evaluated the records of patients with the organoid nevus syndrome who had presented to a tertiary care eye hospital in northern India. The ocular features were studied and entered in MS excel and the data were evaluated. Results: Data of 13 patients with the organoid nevus syndrome were found. All 13 patients had cutaneous features in the form of Sebaceous nevus of Jadasson, 8 patients had alopecia of the scalp area, 2 had history seizures and 10 had arachnoid cysts on neuroimaging of the head. All 13 patients had a complex choristoma involving the ocular surface. Conclusions: We conclude that the most common ophthalmologic features associated with organoid nevus are complex choristoma of the bulbar surface, scleral coat calcification and upper eyelid coloboma.
