ABCA4 is one of the main genes which mutations are associated with various inherited retinal diseases (IRD) such as Stargardt disease, cone dystrophy, cone-rod dystrophy, and retinitis pigmentosa. Wide prevalence of IRD, high heterogeneity of ABCA4 gene mutations that lead to impaired function of the protein with varying expressiveness make studying of the clinical and genetic characteristics of retinal diseases relevant for further investigations into pathogenesis, prognosis and outcome of the disease. This article reviews the literature on incidence of IRD caused by mutations in the ABCA4 gene and characteristics of the clinical progression of retinal diseases associated with various types of mutations, and presents analysis of clinical and genetic correlations in terms of the effect the mutation has on the structure or function of the protein.

An improvement in visual acuity accompanied by the development of RPE tear: a case report.
BMC Ophthalmol
January 2025
Department of Ophthalmology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Shuaifuyuan, Dongcheng District, Beijing, 100730, China.
Background: Retinal pigment epithelium (RPE) tear is a well-known complication of RPE detachment and is typically associated with significant visual acuity decline. However, in this case, despite the occurrence of an RPE tear there was an unexpected improvement in visual acuity.
Case Presentation: A 68-year-old male presented with blurred vision in his right eye of a month's duration.
Treatment of pseudophakic aqueous misdirection syndrome.
Sci Rep
January 2025
Department of Ophthalmology, Inselspital, Bern University Hospital, University of Bern, Freiburgstrasse, 3010, Bern, Switzerland.
To describe the management and clinical course of 12 cases of pseudophakic aqueous misdirection syndrome (AMS). Twelve eyes of 12 Patients diagnosed with pseudophakic AMS between 2021 and 2022 were included. Best-corrected visual acuity, refraction, intraocular pressure (IOP), anti-glaucomatous medication, spectral domain ocular coherence tomography (SD-OCT) and postoperative complications were evaluated.

January 2025
Department of Ophthalmology, Ningde Municipal Hospital of Ningde Normal University, Ningde, Fujian, China.
Background: With the aging of the population, the deterioration of visual and auditory functions amongst the elderly has attracted much attention. Age-related hearing loss (ARHL) and age-related macular degeneration (AMD) are common eye and ear diseases that seriously affect the quality of life of elderly population.
Methods: This study utilised a whole cohort sampling method, with a total of 713 participants aged 50 years and older in the community from June 2022 to October 2023, resulting in the inclusion of 620 participants.
Topographic changes in macula and its association with visual outcomes in idiopathic epiretinal membrane surgery.
PLoS One
January 2025
Department of Ophthalmology, Medical Research Institute, Pusan National University Hospital, Busan, South Korea.
Purpose: We investigated changes in macular topography and their association with visual acuity and metamorphopsia in the idiopathic epiretinal membrane (iERM).
Methods: Twenty-four eyes that underwent vitrectomy and ERM removal with internal limiting membrane peeling were included in this study. Best-corrected visual acuity (BCVA) and horizontal/vertical metamorphopsia scores (h and vM-scores in the M-chart) were assessed.
Retrospective study of incidence/prevalence of pigmentary maculopathy and retinopathy in patients receiving pentosan polysulfate sodium.
PLoS One
January 2025
Verana Health, San Francisco, CA, United States of America.
Purpose: To evaluate prevalence and incidence rates of pigmentary maculopathy and retinopathy (PM/PR), and visual acuity (VA) changes in patients exposed to pentosan polysulfate sodium (PPS) and in patients with interstitial cystitis (IC) not exposed to PPS.
Methods: This is a retrospective cohort study (January 2015-March 2021) which included adult de-identified patients from the American Academy of Ophthalmology IRIS® Registry (Intelligent Research in Sight) and Komodo Health database. Three patient cohorts were identified: two PPS-exposed patient cohorts, and Non-PPS-exposed IC patient cohort.
