Two distantly related, two- to three-year-old male Akita dogs developed partial or complete night blindness which progressed to day blindness. Clinical features were attenuated retinal blood vessels, diffuse exaggerated tapetal reflex, and hyperreflective horizontal lines in the tapetal fundus. The principal histologic change was regional photoreceptor cell degeneration. Areas of moderately atr...
We report a case of progressive atrophy of the retinal pigment epithelium (RPE) after trypan-blue-assisted peeling of internal limiting membrane (ILM) for macular hole surgery. A 68-year-old Caucasian female underwent a 20-g pars plana vitrectomy for a chronic stage-3 macular hole. The ILM was stained with 0.06% trypan blue (VisionBlue™, DORC Netherlands) for 2 min after fluid air exchange. Dye...
PURPOSE To characterize a novel early onset canine retinal disease, and evaluate the ATP-binding cassette transporter gene ABCA4 as a potential candidate gene in this and other canine retinal degenerations. METHODS Retinal disease was characterized ophthalmoscopically and electroretinographically in two pit bull terrier dogs and their purpose-bred descendants. All 50 exons of the canine ABCA4...
Retinitis pigmentosa (RP) is a group of hereditary, degenerative retinal disorders characterized by progressive retinal dysfunction, outer retina cell loss, and retinal tissue atrophy. It eventually leads to tunnel vision and legal, or total blindness. Here we aimed to reveal the causal gene and mutation contributing to the development of autosomal recessive RP (arRP) in a consanguineous family...
Retinitis pigmentosa (RP) is a group of human retinal disorders, with more than 100 genes involved in retinal degeneration. Canine and murine models are useful for investigating human RP based on known, naturally occurring mutations. In Schapendoes dogs, for example, a mutation in the CCDC66 gene has been shown to cause autosomal recessively inherited, generalized progressive retinal atrophy (g...
BACKGROUND The study aims to correlate Fourier-domain optical coherence tomography (FD-OCT) with Goldmann visual field (GVF) to show the photoreceptor (PR) structure and function relationship in the first described case of cancer-associated retinopathy (CAR) from Merkel cell carcinoma. FINDINGS A case study of a patient with CAR who was imaged with serial GVF and FD-OCT over a 2-year period w...
