1.  Long-Term Visual and Anatomic Outcomes Following Anti-VEGF Monotherapy for Retinal Angiomatous Proliferation 
To study the long-term visual and anatomic outcomes of anti-vascular endothelial growth factor (VEGF) monotherapy for the treatment of patients with retinal angiomatous proliferation (RAP).
Retrospective review of patients who were diagnosed with AMD and RAP lesions, and who received anti-VEGF injections as the only mode of therapy.
20 eyes (15 patients; 9 women, 6 men) with RAP lesions treated by anti- VEGF were encountered. Mean patient age was 85.8 years (SD ± 4.54). Nine eyes were treated with intravitreal ranibizumab alone, 8 eyes with bevacizumab alone, and 3 eyes received both drugs. At the 1, 3 and 6 month follow-up the median VA had improved from baseline (20/72) to 20/52, (range: 20/25 to 20/400), 20/45 (range: 20/20 to 20/400), and 20/56 (range: 20/20 to 20/400), respectively, (P> 0.001, P= 0.001, and P= 0.05, respectively). At 24 month follow-up, the improvement of VA, defined as halving of the visual angle, occurred in 37.5% of the cases.
Anti-VEGF monotherapy represents a useful treatment option for RAP, with stable or improved visual acuity in 62.5% of patients at 2 years. 25% of eyes only required a single injection, however, in most cases (75%) repeated treatments were required, highlighting the need for long term follow up. Although in this small study, the results for visual improvement were not statistically significant beyond 3 months; our findings warrant further large-scale investigation.

2.  Comparison of the Optical Coherence Tomographic Features of Choroidal Neovascular Membranes in Pathologic Myopia versus Age-Related Macular Degeneration, using Quantitative Subanalysis 
The British journal of ophthalmology  2008;92(8):1081-1085.
To compare the retinal morphologic characteristics of eyes with choroidal neovascularization (CNV) secondary to pathologic myopia versus eyes with CNV secondary to age-related macular degeneration (AMD), using quantitative optical coherence tomography (OCT) subanalysis.
Twenty-one eyes of 21 patients newly diagnosed with CNV secondary to pathologic myopia, and 43 consecutive cases of eyes with newly diagnosed subfoveal CNV secondary to AMD were retrospectively collected. In all patients, StratusOCT images and fluorescein angiograms (FA) were available for analysis. StratusOCT images were analyzed using custom software (termed “OCTOR”), which allowed calculation of the thickness/volume of the neurosensory retina, subretinal fluid (SRF), subretinal tissue (SRT), and pigment epithelial detachments (PEDs). FA images were used to calculate CNV leakage area and CNV lesion size for each eye.
Total volume of neurosensory retina in the pathologic myopia group was significantly less than in the AMD group (7.10 ± 0.50 mm3 versus 7.76 ± 0.93 mm3, P=0.004). Total volume of SRF in the pathologic myopia group was less than in the AMD group, however the difference was not statistically significant (0.33 ± 1.38 mm3 versus 0.55 ± 0.82 mm3, P=0.434). Total volume of SRT in the pathologic myopia group was less than in the AMD group, however the difference was not statistically significant (0.16 ± 0.15 mm3 versus 0.36 ± 0.60 mm3, P=0.144). Total volume of PED in the pathologic myopia group was markedly less than in the AMD group (0.01 ± 0.03 mm3 versus 1.09 ± 1.89 mm3, P<0.001). On FA, the total leakage of CNV in the AMD group was significantly greater than in the pathologic myopia group (4.17 ± 3.29 DAs versus 0.53 ± 0.58 DAs P<0.001).
CNV lesions in pathologic myopia were associated with considerably less retinal edema, SRF, and SRT compared with CNV associated with AMD. PEDs were almost negligible in myopic lesions compared with AMD. These findings are consistent with previous clinical and angiographic descriptions of myopic CNV as relatively small lesions with modest exudation.
