Contrast sensitivity after intravitreal antivascular endothelial growth factor therapy for myopic choroidal neovascularization.
BACKGROUND
To evaluate contrast sensitivity (CS) using Pelli-Robson charts after intravitreal ranibizumab (IVR) (Lucentis, Novartis, Basel, Switzerland) or bevacizumab (IVB) (Avastin, Genentech, South San Francisco, California, USA) in eyes with myopic choroidal neovascularization (mCNV).


METHODS
A retrospective review was performed of 17 consecutive patients treated with IVR (n = 10; 0.5 mg) or IVB (n = 7; 1.25 mg) for mCNV from July, 2006 with follow-ups through September, 2009. Re-treatment was performed at monthly or longer intervals if there was fluorescein leakage in fluorescein angiogram (FAG) and or apparent subretinal fluid in optical coherence tomography (OCT) persisted.


RESULTS
CS improved by a mean of one letter at 1 month (n = 17; p = 0.32), four letters at 3 months (n = 17; p = 0.02), four letters at 6 months (n = 15; p = 0.01), five letters at 9 months (n = 14; p = 0.04) and six letters at 12 months (n = 13; p = 0.03). The mean number of IVR/IVB was 1.6/1.6, 2.6/2.3, 3.1/3.2, 4.1/4.2 and 4.5/4.6 at 1 month, 3 months, 6 months, 9 months, and 12 months, respectively.


CONCLUSIONS
Improvements in Pelli-Robson CS scores were observed during the first year after IVR/IVB in eyes with mCNV.
