Abstract
PURPOSE: To assess the long-term outcome of patients with subretinal neovascular membrane (SRNVM) secondary to type 2 idiopathic juxtafoveolar telangiectasia (IJT) receiving intravitreal anti-VEGF (vascular endothelial growth factor) injections.
METHODS: A total of 14 eyes of 12 patients treated with intravitreal anti-VEGF for SRNVM related to type 2 IJT were retrospectively assessed.
RESULTS: Nine men and 3 women with a mean age of 66 years (SD 12, range 47-87 years) were diagnosed with IJT-related SRNVM. On average, 6.8 injections (SD 5.5, range 3-18) were given per eye. Ten eyes were treated with ranibizumab, 3 eyes with bevacizumab and 1 eye received both substances. The median follow-up after the last injection was 31 months (IQR: 18, 48). In 6 eyes, BCVA improved by 1-4 lines (mean Δ +2.0 lines), 1 eye remained stable and 7 eyes showed decline of vision by 1-5 lines (mean Δ -2.1 lines). The baseline central foveal thickness was significantly reduced from a mean of 323 (SD 87) to 266 µm (SD 71 µm) at the last follow-up visit (p = 0.001).
CONCLUSIONS: SRNVM development is a severe complication of type 2 IJT. Since the establishment of intravitreal anti-VEGF treatment laser coagulation and PDT have lost significance. Intravitreal anti-VEGF therapy seems to be safe and effective for the treatment of IJT-related SRNVM. Frequently multiple intravitreal injections are necessary for stabilisation.
