Neurotrophic Keratitis Following Vitrectomy Surgery: A Case Report.

Neurotrophic keratitis is a rare corneal degenerative disorder characterized by decreased sensory innervation, leading to epithelial defects and impaired wound healing. This report presents a case of a 60-year-old female with a history of type 2 diabetes and prior herpes infection who developed neurotrophic keratitis following ocular surgery for proliferative diabetic retinopathy. Initial treatment targeted infectious keratitis; however, persistent symptoms prompted a revised diagnosis. Management with autologous serum drops resulted in partial resolution of the epithelial defect but left a central leucoma and severely reduced visual acuity. This case highlights the need for early diagnosis and targeted therapy to prevent irreversible corneal damage in patients with high-risk profiles.
