A CASE OF TOXIC KERATITIS FOLLOWING INJURY BY HYMENOPTERAN INSECT- CLINICAL FEATURES AND MANAGEMENT

Abstract

Dr. Rashmi Shetty,

Patient presented with pain, pricking sensation and mild blurring of vision. On examination, visual acuity was 6/6 in the right eye and counting fingers five meters in left eye. Anterior segment examination of left eye showed mild lid oedema, mild conjunctival chemosis and hyperaemia. There was generalised corneal haze, oedema and striate keratopathy with central corneal epithelial defect of about 3mm in diameter with mild infiltration with brown foreign body in 2 O’ clock position mid peripheral cornea (Figure 2). Body of the insect had fallen off by lid movement (Figure 3). And two tiny pieces of brownish foreign bodies (probably Stinger and insect leg) in corneal stroma were noted on slitlamp examination (Figure 4). One was superficial corneal stromal foreign body; and another foreign body was projecting into anterior chamber. Patient had developed immediate extensive toxic and immunological reaction to the foreign body in the form of increasing striate keratopathy, infiltrate and corneal oedema (Figure 5). Pupil was normal and reactive. Lens was clear. Fundus was normal. Ocular movements were normal. Intraocular pressures measured by air puff tonometer were normal.
