Abstract

PURPOSE
To evaluate the 6-month outcomes of intravitreal ranibizumab and aflibercept treatment for patients with retinal angiomatous proliferation (RAP).
METHODS
A retrospective review of medical records of 28 patients (31 eyes) diagnosed with RAP was performed. All patients were initially treated with 3 consecutive intravitreal ranibizumab or aflibercept injections after diagnosis. Additional treatment was performed when exudation recurred. The best-corrected visual acuity (BCVA) and central foveal thickness were measured before the first injection and 3 and 6 months after the first injection. The values measured before the treatment were compared with those after treatment.
RESULTS
Sixteen eyes were treated with ranibizumab and 15 eyes with aflibercept. The logarithm of minimal angle of resolution (log MAR) values of BCVA before the first injection and 3 and 6 months after the first injection were 0.78 +/- 0.50, 0.47 +/- 0.30 and 0.59 +/- 0.41 in the ranibizumab group and 0.96 +/- 0.52, 0.83 +/- 0.52 and 0.74 +/- 0.56 in the aflibercept group, respectively. Central foveal thickness was 315.75 +/- 115.44, 188.38 +/- 57.33 and 218.50 +/- 96.49 microm in the ranibizumab group and 249.00 +/- 74.88, 143.73 +/- 32.73 and 196.73 +/- 94.08 microm in the aflibercept group, respectively. BCVA was significantly improved and central foveal thickness was significantly reduced at 6 months (p < 0.05) compared to measurements before the first injection in both groups. However, BCVA improvement and central foveal thickness were not significantly different between the 2 groups.
CONCLUSIONS
Both intravitreal ranibizumab and aflibercept treatments were beneficial for both normalizing macular thickness and improving visual acuity in patients with RAP. The efficacy of the 2 drugs was not noticeably different.
