PURPOSE: To use highly precise spectral-domain optical coherence tomography (SD-OCT) to determine whether there were structural abnormalities in the layers of different regions of the fovea in children with anisometropic amblyopia. METHODS: Eighteen children (mean age 7.8 years old; range 5-11 years) with unilateral anisometropic amblyopia and 18 age-matched control subjects participated. Foveal thickness was measured with an enhanced depth imaging system, SD-OCT and segmented into layers using custom developed software...

BACKGROUND: Central serous chorioretinopathy (CSC), which has the characteristics of a serous retinal detachment (SRD) in the macular area, affects mostly men in the 30- to 50-yr age range. Some patients have persistent SRD, which may cause retinal thinning and photoreceptor impairment. CSC symptoms are gradual vision loss and/or metamorphopsia. Some commercial airline pilots are concerned about CSC symptoms, which can disqualify them from flying for months and can also reoccur. Thus, careful monitoring and treatment of CSC are critical for pilots, especially those with chronic or recurrent CSC...

PURPOSE: To demonstrate photoreceptor cell injury in Vogt-Koyanagi-Harada (VKH) disease. METHODS: The SD-OCT and FAF tests of 16 patients diagnosed with VKH disease that was followed up from the initial stage to the convalescent stage were reviewed. RESULTS: In the initial stage of VKH disease, there was hyperautofluerescence around the macular edema. In the convalescent stage of VKH disease, loss of photoreceptor and injury of RPE have been detected by OCT scan at the same area, which was corresponded with the abnormalities in FAF...

PURPOSE: To report the fundus manifestations and spectral-domain optical coherence tomographic (SD-OCT) features of dengue fever presenting as Purtscher-like retinopathy. METHODS: Retrospective review of two cases of dengue fever. RESULTS: Color fundus photograph revealed the presence of cotton-wool spots in a Purtscher-like configuration in the posterior pole of all study eyes. SD-OCT demonstrated increased reflectivity signal in the inner retinal layers, and after a variable follow-up period, there was complete disappearance of cotton-wool spots and persistence of the hyperreflectivity signal...

Purpose. Retinal pigment epithelium (RPE) loss in neovascular age-related macular degeneration (nAMD) seem to have a linear progression but might be influenced by the treatment. The purpose of the study is the comparison of RPE loss over three years in patients treated with intravitreal ranibizumab to patients who were switched to aflibercept. Methods. A retrospective analysis with 96 eyes switched to aflibercept was conducted. The progression rate of RPE loss was evaluated in patients who showed atrophy one year prior to switch (n = 17) or on switch date (n = 19)...
