Abnormal Fundus Reflexes and Retinitis Pigmentosa

Abnormal fundus reflexes and retinitis pigmentosa.

Fundus Autofluorescence Lifetime Patterns in Retinitis Pigmentosa.

Purpose We investigated whether fundus autofluorescence (FAF) lifetimes in patients with retinitis pigmentosa display a disease-specific lifetime pattern. Methods Fundus autofluorescence lifetime imaging ophthalmoscopy (FLIO) was performed in two spectral channels (498-560 and 560-720 nm) after excitation with a 473 nm pulsed laser in patients with retinitis pigmentosa and compared to healthy...

Retinitis Pigmentosa Associated with Vasoproliferative Tumors and Coats-like Fundus

PURPOSE To report two cases of retinitis pigmentosa (RP) associated with vasoproliferative tumors (VPTs) and Coats-like fundus. CASE REPORTS Two patients with RP presented with recent loss of vision due to combined VPTs and Coats-like retinal vascular alterations. One patient had two VPTs with adjacent capillary nonperfusion, telangiectasia and aneurysmal vascular changes in one eye. The othe...

Quantifying Fundus Autofluorescence in Patients With Retinitis Pigmentosa

Purpose Using quantitative fundus autofluorescence (qAF), we analyzed short-wavelength autofluorescent (SW-AF) rings in RP. Methods Short-wavelength autofluorescent images (486 nm excitation) of 40 patients with RP (69 eyes) were acquired with a confocal scanning laser ophthalmoscope equipped with an internal fluorescent reference. Mean qAF was measured in eight preset segments (qAF8) and in ...

EXTENDED REPORT Functional characterisation and serial imaging of abnormal fundus autofluorescence in patients with retinitis pigmentosa and normal visual acuity

Aim: To characterise and monitor abnormal fundus autofluorescence (AF) in patients with retinitis pigmentosa (RP) who have good visual acuity. Methods: 21 patients with a clinical diagnosis of RP were examined. All had rod-cone dystrophy (ISCEV standard electroretinograms (ERGs)), visual acuity of 6/9 or better, and manifested a parafoveal ring of high density fundus AF. Repeat AF imaging was p...
