In contrast to USH2A, variants in ADGRV1 are a minor cause of Usher syndrome type 2, and the associated phenotype is less known. The purpose of the study was to characterize the retinal phenotype of 18 ADGRV1 patients (9 male, 9 female; median age 52 years) and compare it with that of 204 USH2A patients (111 male, 93 female; median age 43 years) in terms of nyctalopia onset, best corrected visual acuity (BCVA), fundus autofluorescence (FAF), and optical coherence tomography (OCT) features. There was no statistical difference in the median age at onset (30 and 18 years; Mann–Whitney U test, p = 0.13); the mean age when 50% of the patients reached legal blindness (≥1.0 log MAR) based on visual acuity (64 years for both groups; log-rank, p = 0.3); the risk of developing advanced retinal degeneration (patch or atrophy) with age (multiple logistic regression, p = 0.8); or the frequency of cystoid macular edema (31% vs. 26%, Fisher’s exact test, p = 0.4). ADGRV1 and USH2A retinopathy were indistinguishable in all major functional and structural characteristics, suggesting that the loss of function of the corresponding proteins produces similar effects in the retina. The results are important for counseling ADGRV1 patients, who represent the minor patient subgroup.

Stargardt disease (STGD) is the most common form of recessively inherited macular dystrophy. It is characterized by the presence of an atrophic macular lesion, which is surrounded by irregular, white-yellow, deep retinal lesions (flecks). There is wide variability in age at onset, visual acuity, fundus appearance, and severity of the disease. Fundus examination can be normal but visual acuity can be reduced early in the course of the disease. In these patients, pattern electroretinogram (PERG) and fundus autofluorescence (FAF) will be helped in establishing the diagnosis of STGD. The typical sign of “choroidal silence” or dark choroid on fluorescein angiography (FA) is not present in all patients with STGD and is not specific to this condition.
