Roth-like Spot in an Adult With Vitamin B6 Deficiency and Nonepileptic Seizures

Purpose: This work reports retinal findings in an adult patient with vitamin B6 deficiency. Methods: A case review of a single patient is presented. Results: A patient with a Roth-type retinal lesion and a history of nonepileptic seizures was found to have lymphocytic colitis. She was treated with pyridoxine, which resolved her seizures and the white-centered hemorrhage. Conclusions: Vitamin B6 deficiency should be considered in the differential diagnosis of patients presenting with white-centered hemorrhages and a history of nonepileptic seizures.

A case of chronic retinal necrosis after tube shunt surgery for secondary glaucoma associated with cytomegalovirus corneal endotheliitis

Background We report a case of chronic retinal necrosis (CRN) combined with cytomegalovirus (CMV) corneal endotheliitis. Case presentation An 80-year old man was diagnosed with CRN that developed after tube shunt surgery with vitrectomy for secondary glaucoma associated with CMV corneal endotheliitis. After the use of oral valganciclovir and panretinal photocoagulation, the retinal lesion resolved rapidly and he has maintained visual acuity better than before the onset of CRN. Conclusions Use of oral valganciclovir, prophylactic panretinal photocoagulation for the non- perfusion area and vitrectomy were effective in maintaining the visual acuity for the patient with CRN.

Presumed Retinal Metastasis from Lung Adenocarcinoma: A Case Report and Literature Review

A 63-year-old Caucasian man with metastatic lung adenocarcinoma undergoing chemotherapy and external radiotherapy was referred for routine eye examination. Although he was asymptomatic, ocular examination revealed a relatively well-circumscribed whitish retinal lesion measuring 0.5 × 0.5 × 0.5 mm located along the inferotemporal vascular arcade in the right eye. Optical coherence tomography (OCT) showed a hyperreflective dome-shaped lesion occupying the inner retinal layers with few hyperreflective dots overlying the retina in the posterior vitreous consistent with tumor cells. Fluorescein angiography revealed early hyperfluorescence and late staining without leakage at the lesion site. A diagnosis of presumed retinal metastasis from lung adenocarcinoma was made. At 2 months follow-up after completion of chemotherapy, the retinal lesion was found to have regressed completely leaving minor irregularities in the inner retinal layers on OCT. To date, there have been only 41 cases of carcinoma metastasis to the retina reported in the literature including the current case. Despite its rarity, retinal metastasis should be considered in the differential diagnosis of a white-yellow retinal mass with/without overlying vitreous cells especially in patients with a history of systemic cancer.

Endophthalmitis in Retinopathy of Prematurity after Intravitreal Aflibercept Injection

We report the case of a male infant who had an intravitreal anti-VEGF (aflibercept) injection for the treatment of retinopathy of prematurity at 35-week postmenstrual age. Four days following the injection, retinal imaging demonstrated a yellowish gray blurred mass that extended into the vitreous in the right eye, and the vitreous body was blurred. After two days, despite starting endophthalmitis treatment, there was still no improvement in the retinal lesion. Due to the worsening of the clinical signs, we decided to perform 25-gauge lens-sparing pars plana vitrectomy.
