An outbreak of Pythium keratitis in Northeast Thailand was reported. Distinctive clinical features are a suggestive clue for early diagnosis. Combination treatment including topical antifungal agents, radical surgery, and P. insidiosum vaccine may be considered for the management of Pythium keratitis.

Intralesional bevacizumab may have a therapeutic effect on symptoms and signs of primary pterygium for at least 6 months (ie, the follow-up period), with no serious ocular or systemic adverse effects.
