WebJan 11, 2024 · IRDs are a complex group of genetic disorders that arise from mutations in the over 300 different genes associated with retinal pathology ( 2, 3 ). These genes are critical for photoreceptor (PR) and retinal pigment epithelium (RPE) function and when compromised, progressive cell death leads to blindness ( 4, 5 ). WebInherited retinal dystrophy (IRD) is a subset of degenerative diseases of the retina which have marked clinical, molecular, and genetic heterogeneity. Clinical presentation can be variable and include night or color blindness, tunnel vision, visual field defects, and subsequent progression to complete blindness.

WebContemporary structural assessment of the retina in IRDs is centred around the use of two core technologies: optical coherence tomography (OCT), and fundus autofluorescence (FAF). OCT is a non-invasive imaging modality that uses low coherence interferometry to quantify the intensity of light reflected from different structures within the retina. WebJun 4, 2024 · Inherited retinal diseases (inherited retinal dystrophies; IRDs) are a heterogeneous group of ocular neurodegenerative disorders resulting from mutations in any one of over 250 causative genes [ 1 ]. They are mostly characterised by progressive retinal degeneration that leads to severe visual impairment and blindness [ 2, 3, 4, 5, 6 ].
WebPRPH2 gene mutations are frequently found in inherited retinal dystrophies (IRD) and are associated with a wide spectrum of clinical phenotypes. We studied 28 subjects affected by IRD carrying pathogenic PRPH2 mutations, belonging to 11 unrelated families.
