Aim: To report a patient who developed acute nonarteritic ischemic optic neuropathy following conjunctival melanoma excisional biopsy.
Method: Case report.
Results: An otherwise healthy 55-year-old man presented with a three-month history of progressively growing pigmented lesion in the left eye. Clinical examination revealed a dark pigmented conjunctival lesion adjacent to temporal limbus with an evident feeder vessel. With the initial diagnosis of conjunctival melanoma; excisional biopsy, alcohol epitheliectomy, cryotherapy (double-thaw), episclerectomy, and amniotic membrane transplantation for ocular surface reconstruction were performed. Histopathological examination confirmed the diagnosis. Four months after surgical intervention, sudden visual loss in the operated eye occurred. According to detailed neuroophthalmological examination, patient was diagnosed as acute nonarteritic ischemic optic neuropathy.
Conclusion: Nonarteritic ischemic optic neuropathy is a multifactorial disease and may occur after several ophthalmic surgeries. To the best of our knowledge this is the first reported case of nonarteritic ischemic optic neuropathy following conjunctival melanoma excision.
