Longitudinal changes in choroidal thickness and choroidal vascularity index in age-related macular degeneration.
Introduction: To investigate the rate of choroidal thinning and choroidal vascularity index (CVI) changes over time in eyes with different stages of age-related macular degeneration (AMD) and control eyes.
Methods: Retrospective longitudinal study of 105 eyes with different stages of AMD: non-advanced (n=46), exudative (n=28), central cRORA (n=5) and healthy eyes (n=26). We evaluated choroidal thickness (CT) and CVI at baseline and during 2-4 years of follow-up. After adjustment for age and sex, we estimated the rate of change per year of CT and CVI in each group. We also performed logistic regression to analyze the relationship between baseline CT and CVI with AMD progression.
Results: The mean age of the included patients was 77.1 years with a mean follow-up of 3.36 years. Healthy eyes had higher baseline CT and CVI values compared to eyes with AMD. Exudative AMD showed a significant annual decrease in subfoveal CT (-5.1% per year vs. -3.5% in controls) and in the temporal and nasal sectors (-5.3% and -6.3%). CVI decreased during follow-up in all study groups, most in eyes with central cRORA (-1.09% per year).
Conclusion: CVI and CT values are reduced in eyes with AMD compared to healthy eyes. Eyes with exudative AMD have the highest annual rate of choroidal thinning, while CVI decreases most in eyes with central cRORA. CT and CVI may aid in a further stratification of AMD progression risk.
期刊介绍：
''Ophthalmic Research'' features original papers and reviews reporting on translational and clinical studies. Authors from throughout the world cover research topics on every field in connection with physical, physiologic, pharmacological, biochemical and molecular biological aspects of ophthalmology. This journal also aims to provide a record of international clinical research for both researchers and clinicians in ophthalmology. Finally, the transfer of information from fundamental research to clinical research and clinical practice is particularly welcome.
