Purpose: To report a rare case of infusion port site tumor seeding of choroidal melanoma after pars plana vitrectomy-assisted biopsy and successful treatment with second plaque brachytherapy., Methods: Observational case report with clinical data and diagnostic images., Results: A 55-year-old White woman diagnosed with choroidal melanoma of the left eye was found to have a second intraocular tumor 30 months after plaque brachytherapy and pars plana vitrectomy-assisted tumor biopsy. The second melanoma developed at the 5 o'clock vitrectomy infusion port site. The tumor regressed after plaque brachytherapy, and the patient has not developed systemic metastasis 5 years after diagnosis of intraocular seeding., Conclusion: Intraocular seeding into the infusion port site, although rare, may be encountered after pars plana vitrectomy-assisted biopsy of choroidal melanoma.

Purpose: To present a novel case of exogenous Rahnella aquatilis endophthalmitis following an intravitreal injection., Methods: Case report., Results: A 74-year-old male presented with acute progressive vision loss and pain in the left eye, 5 days after an intravitreal injection for diabetic macular edema. The patient was diagnosed with exogenous endophthalmitis and empirically treated with intravitreal injections of vancomycin and ceftazidime as well as topical and oral ciprofloxacin. In follow up two days later, the patient was treated with preoperative povidone-iodine followed by prompt vitrectomy with additional vancomycin and ceftazidime due to pharmacy sterile hood issues that delayed antibiotic availability. Microbiological cultures and two mass spectrometry identification tests confirmed the diagnosis of exogenous Rahnella aquatilis endophthalmitis. Despite the presence of scattered retinal hemorrhagic infarcts involving the macula and subsequent full-thickness atrophic macular holes seen in follow up, the patient achieved a favorable anatomical and functional outcome of BCVA 20/80 at 1 year of follow-up., Conclusion: This case highlights the occurrence of exogenous Rahnella aquatilis endophthalmitis following an intravitreal injection for diabetic macular edema. Prompt diagnosis and treatment produced a favorable outcome relative to other typical Gram-negative Enterobacteriaceae organisms.

Purpose: Adams-Oliver syndrome is a rare, inherited disorder of embryologic development that affects multiple systems. Ocular manifestations have been poorly characterized because of the low prevalence and high mortality of the disease when it is associated with internal organ and/or ophthalmic manifestations. We present a case of Adams-Oliver syndrome in a 13-year-old patient whose multimodal retinal imaging findings helped direct management., Methods: Single patient case report reviewing medical records and imaging., Results: Visual acuity upon presentation was 20/40 in each eye. Ultra-widefield fluorescein angiography revealed peripheral nonperfusion with terminal vascular bulbs, and leakage from a temporal fibrovascular complex in the left eye. Fundus autofluorescence imaging showed hyperautofluorescence associated with optic disc drusen and the fibrovascular complex. Treatment with targeted laser photocoagulation was associated with regression of the neovascularization., Conclusion: Retinal manifestations of Adams-Oliver syndrome as observed with ultra-widefield fundus imaging may resemble those of familial exudative vitreoretinopathy and retinopathy of prematurity. Treatment of avascular retina with panretinal photocoagulation can be considered.

Purpose: To report a unique case of dramatic improvement in objective visual function during the recovery phase, after resolution of thrombotic thrombocytopenic purpura-related serous retinal detachments and to review prognostic trends in reported cases involving the macula., Methods: Observational case report and literature review., Results: A 36-year-old white woman with thrombotic thrombocytopenic purpura developed vision loss from serous retinal detachments in both eyes. Over a 16-month period, after both retinae remained attached, best-corrected visual acuity improved from 20/400 to 20/50 in both eyes with dramatic improvement on optical coherence tomography and autofluorescence imaging., Conclusion: Although thrombotic thrombocytopenic purpura is a life-threatening illness, visual prognosis in patients with macula off serous retinal detachments appears excellent. Most cases reviewed in literature improved to baseline visual acuity, but recovery periods ranged from days to many months. Hyperautofluorescent granularity on autofluorescence photography may be an indicator of chronic retinal detachment and a more delayed visual recovery.
