Human immunodeficiency virus retinopathy with presumed cytomegalovirus retinitis with macular oedema in a diabetic.

A man in his early 50s on regular follow-up for a stable non-proliferative diabetic retinopathy (NPDR) presented with decreased vision, worsening of retinal pathology and macular oedema in both eyes. His corrected distance visual acuity (CDVA) was 6/9 in the right eye and 6/15 in the left eye and fundus examination showed multiple intraretinal haemorrhages in all quadrants. His systemic workup revealed a severe thrombocytopaenia, which prompted a further detailed systemic evaluation revealing him to be positive for HIV with retinopathy complicating the pre-existing NPDR. Given the significant inflammation and macular oedema, a cocktail of intravitreal bevacizumab, ganciclovir and dexamethasone was administered. The retinopathy and macular oedema resolved and the CDVA improved to 6/6 in both eyes over a 6-month follow-up period. Any sudden worsening of fundus findings in a patient with diabetes necessitates immediate and detailed ocular and systemic evaluation, especially when the immune status is unknown.
