Delayed-onset, bleb-associated endophthalmitis caused by Lecythophora mutabilis.

PURPOSE: To report delayed-onset, bleb-associated endophthalmitis caused by Lecythophora mutabilis. DESIGN: Interventional case report. METHODS: Description of an otherwise healthy woman who developed delayed-onset fungal endophthalmitis associated with a preexisting filtering bleb. RESULTS: A 57-year-old woman who underwent trabeculectomy with Mitomycin C in her left eye 8 years earlier presented with a 10-day history of pain and decreased vision in her left eye. She underwent anterior chamber and vitreous taps and injection of intraocular antibiotics. Cultures grew the mold Lecythophora mutabilis. The patient underwent treatment with intraocular and systemic antifungal agents, three pars plana vitrectomies, partial iridectomy, and cryopexy to the bleb and angle structures. Four months after her last treatment, her left eye shows no residual infection, and vision corrects to 20/80. CONCLUSION: Bleb-associated endophthalmitis caused by L. mutabilis is resistant to amphotericin B but responsive to intravitreal and systemic voriconazole together with pars plana vitrectomy, iridectomy, and cryopexy to the bleb and angle structures.

Optical coherence tomographic findings in acute exudative polymorphous vitelliform maculopathy.

PURPOSE: To report two cases of acute exudative polymorphous vitelliform maculopathy. DESIGN: Observational case reports. METHODS: Fluorescein angiography, optical coherence tomography, and electrophysiology were performed. RESULTS: Both patients presented with sudden onset of blurred vision and bilaterally symmetric, central, and perimacular vitelliform lesions. Perimacular lesions were faintly hyperfluorescent early in the disease, but there was no abnormal fluorescence in the macular centers. Optical coherence tomography revealed anterior displacement of the photoreceptor layer by a hypereflective subretinal layer overlying a hyporeflective space above the retinal pigment epithelium-choriocapillaris complex under all lesions and no subretinal fluid. The electrooculogram was abnormal. Near complete resolution occurred over 4 to 8 months, with no improvement in the electrooculogram. CONCLUSIONS: Transient multifocal vitelliform lesions suggest a diagnosis of acute exudative polymorphous vitelliform maculopathy. Optical coherence tomography reveals characteristic anterior displacement of the photoreceptor layer by a subretinal hypereflective deposit similar to that seen in adult-onset foveomacular vitelliform dystrophy.
