The pathogenesis is multifactorial, involving patient-specific immune responses, drug-specific properties including aggregation or impurities, and deviations in preparation or delivery techniques. Clinical presentations range from anterior uveitis and vitritis to occlusive retinal vasculitis. Visual outcomes vary and depend on prompt recognition and appropriate management. Epidemiologic data show variable incidence across agents, with brolucizumab demonstrating higher rates of inflammation compared with ranibizumab or aflibercept.

Innovations in big data, particularly involving large population biobanks, have enabled improved data sets that facilitate a better understanding of connections between the retina and systemic health. Retinal fundus and optical coherence tomography imaging data provide rich resources for describing interpretable imaging endophenotypes and evaluating their utility as biomarkers for future ocular and systemic conditions. Furthermore, the addition of genomic data to retinal and ophthalmic information has enabled unbiased discovery of the biological mechanisms driving changes in the retina. Assessment of inherited common and rare variants influencing ocular phenotypes through genome-wide association studies, in silico analyses for gene prioritization, pathway enrichment analysis, and experimental validation may enable the identification of biological targets for therapeutic modulation of retinal microvascular indices, neuronal health, and other imaging biomarkers. Further development of polygenic risk scores for retinal phenotypes enables a personalized medicine approach to quantifying inherited disease risk for an individual. While interpretation of causality from observational associations is difficult, Mendelian randomization (MR) analyses utilizing genomics can help improve understanding of the causal relationship between different phenotypes. Given the routine, noninvasive nature of retinal imaging, the findings from retinal cross-phenotype and genome-wide analysis have the direct potential for application clinically including in diagnosis, monitoring and prevention, and in treatment of both ocular and systemic conditions.</p>","PeriodicalId":14338,"journal":{"name":"International Ophthalmology Clinics","volume":"65 3","pages":"40-47"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144553519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The driving force behind these acquisitions is the potential for high returns through operational efficiencies, increased bargaining power with insurers, and access to lucrative outpatient procedures. However, PE's impact on the quality and cost of ophthalmic care remains unclear. Studies show mixed results: some report increased use of expensive treatments and higher costs, while others suggest minimal changes in patient outcomes or spending. PE's appeal to ophthalmologists includes capital infusion for practice expansion and improved risk management, though concerns exist over profit-driven incentives possibly compromising patient care. The market for ophthalmology practices remains fragmented, with PE firms capitalizing on consolidation opportunities. Despite the growth, there are challenges to assessing the full impact of PE involvement, particularly due to limited research, nondisclosure agreements, and difficulty in selecting control practices for comparison. While PE acquisitions have been accelerating, recent reports indicate a slowdown in 2024, influenced by factors such as interest rates and federal investigations into the health care sector.
