BackgroundSub-retinal abscess as the presenting feature in the setting of endogenous fungal endophthalmitis is extremely infrequent. Immunodeficiency states are major predisposing risk factors. To the best of our knowledge, this is the first case report of Candida sub-retinal abscess as initial presentation in an immunocompetent patient.Case presentationA 32-year old, generally fit and well, female presented to us with gradually deteriorating vision in her right eye. Visual acuity was counting fingers in the right eye and, 20/30 in the left eye. Right eye fundus examination showed a full thickness, yellowish-white foveal lesion, and significant vitreous haze. Left eye examination was normal. Upon direct questioning, the patient disclosed history of backstreet abortion 3 weeks prior to the onset of her ocular symptoms. She underwent vitreous tap and intravitreal antibiotics (amphotericin B, 5 μg/0.5 ml). Vitreous culture showed profuse growth of Candida albicans. Because her condition was progressively deteriorating, she underwent 25 g vitrectomy plus repeat intravitreal amphotericin B under general anaesthesia. Three weeks post-vitrectomy, vitreous inflammation resolved completely, and the sub-retinal abscess healed with a macular scar formation. Over a follow-up of 4 years, no recurrences were observed.ConclusionOur case highlights the importance of considering Candida albicans infection in the differential diagnosis of sub-retinal abscesses. Although immunocompromised states are traditionally identified as predisposing factors for fungal infections, fungal endogenous endophthalmitis can occur in healthy individuals as well.
