Background: Ultra-widefield angiography is the latest technology in the evolution of fundus fluorescein angiography. With the ability to capture up to 200° of the fundus in a single image, far peripheral retinal pathology can be imaged. Generally, obtaining high-quality fundus fluorescein angiography in a child without sedation in the outpatient setting is exceedingly challenging. Therefore, there are advantages to imaging platforms that can capture the peripheral retina in young children without anesthesia...

Background: For the majority of eyes with choroidal melanoma, radiation therapy is the treatment of choice. Local recurrence after radiation therapy can occur, however, and when it does, salvaging the globe with useful vision is atypical. Case presentation: We report a case of late, local failure 7 years following previous brachytherapy successfully managed with Gamma Knife radiosurgery (GKR). With 3 years of follow up after GKR, the visual acuity is 20/20 and there is no evidence of systemic metastases...

Background and objectives: Advances in neonatal care promoted increased survival rates of preterm infants, with a consequent increase in the number of children affected by retinopathy of prematurity (ROP). This study estimates the incidence of ROP and evaluates potential risk factors associated. Methods: A retrospective cohort study of preterm infants born in a tertiary neonatal intensive care unit was conducted from March 2005 to August 2015. Six hundred and thirty-nine newborns were included based on the following criteria: infants born with less than 32 weeks' gestation or birth weight below 1500 g; or neonates born with 32-37 weeks' gestation or birth weight above 1500 g and any of the following associated: multiple gestation, respiratory distress syndrome, sepsis, blood transfusions or intraventricular hemorrhage...

Background: To describe the recent diagnostic and treatment options for the most predominant form of primary vitreoretinal lymphoma (PVRL), namely diffuse large B cell lymphoma. This is mainly based on the experience at the Mayo Clinic as well as a partial review of the literature. MYD88 L265P mutation is seen in about 80% of cases; therefore, a polymerase chain reaction for this mutation helps in making the diagnosis that has been notoriously difficult to make. Local therapy using intravitreal methotrexate and rituximab has been very helpful in the treatment of the local disease...

Background: Methylenetetrahydrofolate reductase (MTHFR) genetic mutations and intra-procedural inhaled nitrous oxide (N2 O) independently increase blood levels of homocysteine, a compound associated with thrombosis. Patients with MTHFR mutations who also receive N2 O during ophthalmic artery chemotherapy (OAC) for retinoblastoma may have a heightened thrombotic risk. Case presentations: Single-center retrospective review of pediatric patients with advanced retinoblastoma who received OAC and developed choroidal infarcts...

Background: Retinal pigment epithelium (RPE) plays a significant role in maintenance of integrity of retinal photoreceptors and choriocapillaries. RPE derives its blood supply through ophthalmic artery (OA) via choriocapillaries. RPE topographic alterations have been observed to be associated with severity of retinopathy. The present study was undertaken to assess the correlation between resistive index (RI) of the OA with RPE topographic alterations on Spectral-Domain optical coherence tomography (SD-OCT), to our knowledge, it is for the first time...
