Abstract

Background/aaims: Congenital stationary night blindness (CSNB) is an inherited retinal disease that is often associated with high myopia and can be caused by pathological variants in multiple genes, most commonly CACNA1F , NYX and TRPM1 . High myopia is associated with retinal degeneration and increased risk for retinal detachment. Slowing the progression of myopia in patients with CSNB would likely be beneficial in reducing risk, but before interventions can be considered, it is important to understand the natural history of myopic progression.<br />Methods: This multicentre, retrospective study explored CSNB caused by variants in CACNA1F , NYX or TRPM1 in patients who had at least 6 measurements of their spherical equivalent of refraction (SER) before the age of 18. A mixed-effect model was used to predict progression of SER overtime and differences between genotypes were evaluated.<br />Results: 78 individuals were included in this study. All genotypes showed a significant myopic predicted SER at birth (-3.076D, -5.511D and -5.386D) for CACNA1F , NYX and TRPM1 respectively. Additionally, significant progression of myopia per year (-0.254D, -0.257D and -0.326D) was observed for all three genotypes CACNA1F , NYX and TRPM1 , respectively.<br />Conclusions: Patients with CSNB tend to be myopic from an early age and progress to become more myopic with age. Patients may benefit from long-term myopia slowing treatment in the future and further studies are indicated. Additionally, CSNB should be considered in the differential diagnosis for early-onset myopia.<br />Competing Interests: Competing interests: None declared.<br /> (© Author(s) (or their employer(s)) 2024.
