Abstract

Purpose: To report a case of ocular toxoplasmosis as a rare complication of intravitreal dexamethasone
implant in a case of diabetic macular edema.
Methods: A 56 years old male, a known case of Proliferative Diabetic Retinopathy, received intravitreal
dexamethasone implant for diabetic macular edema in left eye. He developed toxoplasma retinochoroiditis
involving the macula with further diminution of vision in his left eye 3 weeks after the injection. His
serum titres were positive for Toxoplasma IgG and IgM. He was treated with oral Sulfamethoxazole
800 mg + Trimethoprim 160 mg 12 hourly for 4 weeks.
Results: The visual acuity in left eye improved with resolution of retinochoroiditis after the course of
antibiotic therapy.
Conclusion: It is imperative to follow-up closely after intravitreal steroid implantation, to look for the
possible rare complication of infectious retinitis/retinochoroiditis, as timely antimicrobial treatment can
lead to a good visual outcome.
