ABSTRACT
PURPOSE:
To assess the incidence, clinical features and predictive risk factors of subretinal fibrosis after treatment of active myopic choroidal neovascularisation (mCNV) with anti-vascular endothelial growth factor (VEGF).METHODS:
This post-hoc analysis of a randomised controlled trial included a total of 54 patients with active mCNV. The clinical data at baseline, month 3 and month 12 were used. Fundus photography and optical coherence tomography at month 3 were used to determine the presence of subretinal fibrosis after anti-VEGF therapy, and its incidence was calculated. Best-corrected visual acuity (BCVA), Visual Function Questionnaire-25 score, macular integrity index (MI) and their changes were compared between eyes with and without subretinal fibrosis. A logistic regression model was used to evaluate the risk factors of subretinal fibrosis.RESULTS:
Subretinal fibrosis occurred in 22 of 54 eyes with mCNV. Patients with subretinal fibrosis achieved similar BCVA improvement in comparison with those without fibrosis at 3 and 12 months after the treatment; however, they had lower visual acuity, more subfoveal CNV (p=0.002), higher CNV thickness at baseline (p=0.016), larger CNV size (p=0.030), larger leakage area (p=0.021) and higher presence of advanced myopic maculopathy (p=0.035). Age <45 years, BCVA <60 ETDRS letters, and MI index <20 at baseline were the predictors for subretinal fibrosis occurrence in a logistic regression model.CONCLUSIONS:
The incidence of subretinal fibrosis after anti-VEGF therapy was 40.7% in eyes with mCNV. Age, baseline BCVA and MI index could serve as predictive risk factors of subretinal fibrosis after anti-VEGF treatment in patients with mCNV.Palabras clave
