Intravitreal injection of anti-VEGF agents in wet age-related macular degeneration: a 5-year retrospective study
Journal Title: Eye Science (Yanke Xuebao) - Year 2022, Vol 37, Issue 7
Abstract
[Objective:] To investigate the efficacy of anti-VEGF injection in the treatment of wet age-related macular degeneration (wAMD) for 5 years. [Methods:] A total of 84 patients (103 eyes) wAMD diagnosed in Department of Ophthalmology in Beijing Hospital from 2011 to 2021 were analyzed retrospectively. 3 + PRN regimen was applied for anti-VEGF treatment. The changes of best corrected visual acuity (BCVA), the number of intravitreal injections and the number of follow-up visits, and the anatomical changes of the lesions in the past 5 years were collected. [Results:] The average BCVA after 5 years was 38.1 letters, indicating a decrease of 9.4 letters comparing to baseline, which was statistically significant (P<0.001). 23.3% of the eyes could maintain the baseline BCVA after 5 years. The average injection times within 5 years was 13.8, and the injection was concentrated in the first year, with an average of 4.3. The average number of follow-up visits within 5 years was 24.3, and only 34.0% of the affected eyes could keep the follow-up interval ≤3 months. After 5 years, 68.0% of the eyes developed fibrous scar, 27.2% developed geographic atrophy, and 69.0% (71/103) had consistent pigment epithelial detachment. Factors significantly affect BCVA include: age, baseline BCVA, initial treatment, follow-up time, injection times, central retinal thickness, geographic atrophy and so on. [Conclusion:] Most patients can maintain vision within the first year after anti-VEGF treatment, but the efficacy is poor for more than 5 years. Early diagnosis and treatment, and increased injection frequency may be the research direction for improving prognosis in the future.
