But not in all forms of herpetic keratitis :-\n\n\nEpithelial herpetic keratitis (Dendritic ulcer, geographic ulcer) → Topicla corticosteroids are contraindicated.\nStromal keratitis (Disciform & Diffuse necrotic) → Topical corticosteroids along with topical antiviral drugs are used as the first line of treatment.\n\n\nSo, my opinion for this type of question is that :-\n\ni)\xa0If herpetic keratitis has given as the option, then look at other options. If any of the other options is a clear cut contraindication for corticosteroid (e.g. fungal corneal ulcer in this question), consider that option as your answer. If no ther option is a contraindication for topical corticosteroid, consider herpetic keratitis as the answer.\nii)\xa0If examiner has specifically mentioned dendritic ulcer as an option, consider it as the answer.", 'role': 'assistant'}]
