A genealogical link was established six generations back between a family living in England and Australia, and one of the families reported originally by Sorsby et al (1949) as suffering from autosomal dominant inflammatory macular dystrophy (fundus dystrophy). The onset--in the fifth decade of life--and the progress of the condition, which usually ends in blindness, has been observed in a number of patients and the prodromal development of a colour vision deficiency in some of them confirmed. This defect is fundamentally different from the X-linked colour vision defects and merits further investigation.

Background: Nineteen-year follow-up after initial examination on patients with Axenfeld-Rieger anomaly or syndrome (ARAS) and coexisting Fuchs' endothelial dystrophy (FED). All individuals had previously been tested positive for the PITX2 (g.20 913 G>T) mutation.

Pediatric macular disorders are a diverse group of inherited retinal diseases characterized by central vision loss due to dysfunction and degeneration of the macula, the region of the retina responsible for high-acuity vision. Common disorders in this category include Stargardt disease, Best vitelliform macular dystrophy, and X-linked retinoschisis. These conditions often manifest during childhood or adolescence, with symptoms such as progressive central vision loss, photophobia, and difficulty with fine visual tasks.

Background/objectives: The interphotoreceptor matrix proteoglycans 1 and 2 (IMPG1 and IMPG2) are two interdependent proteoglycans of the interphotoreceptor matrix (IPM). Mutations in IMPG1 or IMPG2 are linked to retinal diseases such as retinitis pigmentosa (RP) and vitelliform macular dystrophy (VMD), yet the specific mutations responsible for each condition remain undefined. This study identifies mutations in IMPG1 and IMPG2 linked to either RP or VMD.

Background: Leber congenital amaurosis (LCA), the most severe form of inherited retinal dystrophy, is a rare, heterogeneous, genetic eye disease associated with severe congenital visual impairment. RPE65, one of the causative genes for LCA, encodes retinoid isomerohydrolase, an enzyme that plays a critical role in regenerating visual pigment in photoreceptor cells.
Methods: Exome sequencing (ES) was performed on a patient with suspected LCA.
Hardy-Rand-Rittler colour vision testing in cone and cone-rod dystrophies: correlation with structural and functional outcome measures.
Eye (Lond)
January 2025
Save Sight Institute, Faculty of Medicine and Health, The University of Sydney, Sydney, NSW, Australia.
Purpose: To determine how Hardy-Rand-Rittler (HRR) colour vision testing correlates with visual functional and structural assessments in Cone and Cone-Rod Dystrophy.
Methods: Thirty-four Cone and 69 Cone-Rod Dystrophy patients diagnosed by electroretinography (ERG) at the Save Sight Institute in Sydney were included in a retrospective analysis. Each patient's HRR colour vision test scores were compared with markers of cone and rod system function including visual acuity (VA), ERG responses, changes on Spectral Domain Optical Coherence Tomography (OCT) and Fundus Autofluorescence.
