| Phenotype details |
Visual acuity was 20/200 in the right eye and 20/40 in the left eye after correcting for moderate refractive error (?6.5 ? 0.25 × 50 right eye; ?6.25 ? 0.25 × 190 left eye). Intro-ocular pressures (IOP) were 12 mmHg and optic cup-to-disk ratios 0.2 in both eyes. Slit-lamp examination of the anterior segment was unremarkable. Dilated fundus examination found granular mottling of the retinal pigment epithelium (RPE) and welldelineated lesions of chorioretinal atrophy in both eyes. Fundus autofluorescence (FAF) imaging confirmed the presence of bright granular deposition corresponding to the RPE mottling observed on fundoscopy. Peripapillary sparing of disease changes around the optic nerve, a pathognomonic feature of ABCA4, was noted in both eyes. |
