Double focal choroidal excavation with choroidal neovascularization

Splitting of retinal pigment epithelium and Bruch's membrane due to a focal choroidal excavation

We report an unusual finding of a split between the Bruch's membrane (BM) and retinal pigment epithelium (RPE) due to a focal choroidal excavation (FCE) in a healthy young girl with sudden onset visual disturbance. She was followed up regularly for over a year with serial optical coherence tomography (OCT) scans which …

Swept-source optical coherence tomography study of choroidal morphology in Stargardt disease

Background: Stargardt disease, a juvenile retinal dystrophy, may show secondary changes in the choroid which may have importance while considering future treatments such as stem cell transplant. Objective: To evaluate the choroidal and retinal morphology in patients with Stargardt disease and compare with age-matched n …

Retinopathy of prematurity like retinopathy in full-term infants

Purpose: The purpose of this study is to assess clinical characteristics, risk factors, and management outcomes of retinal changes similar to retinopathy of prematurity (ROP), seen in full-term infants. Patients and methods: This is a retrospective review of 46 eyes of 23 patients, born at full term or near full term a …

Localized retinal degeneration secondary to Waldenström's macroglobulinemia

A 52-year-old man, treated for Waldenström's macroglobulinemia (WM), continued to experience decreased vision even after 24 months. He was evaluated using multimodal imaging and electroretinography. The retina did not show any hyperviscosity changes but revealed a yellow lesion at macula with atrophic changes causing a …

Long-term results of intravitreal ranibizumab for osteoma-related choroidal neovascularization in a child

Though choroidal osteoma is a rare benign tumor, associated choroidal neovascularization (CNV) can be a cause of severe visual loss. A nine-year-old boy presented with one-month history of decreased vision in left eye. Upon a complete ophthalmologic examination, including fundus fluorescein angiography and optical cohe …

Surgery for macular holes associated with unusual concomitant pathologies

Macular hole (MH) is uncommonly seen in association with retinitis pigmentosa (RP), optic disc pit or choroidal coloboma. The visual disability in eyes with RP, optic disc pit or choroidal coloboma can range from mild to severe. However, the macula may not be involved in the primary pathology and hence, the central vis …

Comparison between Humphrey Field Analyzer and Micro Perimeter 1 in normal and glaucoma subjects

Purpose: To determine the correlation between fundus perimetry with Micro Perimeter 1 (MP1) and conventional automated static threshold perimetry using the Humphrey Field Analyzer (HFA) in healthy individuals and in subjects with glaucoma. Materials and methods: In this study, we enrolled 45 eyes with glaucoma and 21 e …
