Background: We report a case with bilateral endogenous fungal subretinal abscesses. To our knowledge, this is the first report from Japan in which Scedosporium prolificans (S. prolificans) was cultured from intraocular tissue.
Case: A 74-year-old man, receiving chemotherapy for acute myeloid leukemia, complained of visual loss in both eyes. Best-corrected visual acuity was hand motion in the right and 2/200 in the left eye. His right eye showed exophthalmos, inflammation in the anterior chamber and iris neovascularization. Funduscopy revealed no details as there was vitreous opacity in the right eye, and irregular round yellowish-white subretinal lesions involving the macula in the left eye. Blood culture was negative, and C-reactive protein (CRP) and β-D glucan titers were high. An antifungal drug and broad-spectrum antibiotics were initiated. Two days after the initial visit, right visual acuity had deteriorated to light perception. Enucleation of the right eye was performed for diagnosis and treatment. Fungi were cultured from the subretinal lesion, confirming a diagnosis of S. prolificans infection. After systemic administration and intravitreal injections of antifungal agents, the subretinal abscess in the left eye gradually diminished. At present, six months after the first visit, left visual acuity is 20/200.
Conclusion: Although S. prolificans endophthalmitis can be intractable, this case suggests that repeated intravitreal antifungal agent injections can be effective.
