Purpose: To report features of neovascular age-related macular degeneration (AMD) in Brazilian patients. Procedures: Data were prospectively collected from patients diagnosed with neovascular AMD. Eyes were classified as having typical neovascular AMD, polypoidal choroidal vasculopathy (PCV), or retinal angiomatous proliferation (RAP). Results: In total, 265 eyes of 207 patients of predominantly Caucasian ancestry were included; 166 (62.6%) eyes had typical neovascular AMD, 65 (24.5%) eyes had PCV, and 34 (12.8%) eyes had RAP. RAP demonstrated a higher percentage of bilateral cases (p = 0.015). The mean foveal subfield thickness was significantly lower in eyes with PCV (p < 0.001). Cases with typical neovascular AMD had a higher percentage of predominantly classic and minimally classic lesions on fluorescein angiography (FA; p = 0.005). Conclusions: In Brazilian patients, PCV and RAP represented 24.5 and 12.8% of neovascular AMD cases. Neovascular AMD subtypes differ in relation to clinical features, mean foveal subfield thickness and FA presentation.

Purpose: To compare the response to ranibizumab between patients with typical neovascular age-related macular degeneration (tAMD) and those with polypoidal choroidal vasculopathy (PCV), and to determine the predictors for the outcomes. Methods: Fifty-nine eyes from 59 consecutive patients (tAMD: 27 eyes, PCV: 32 eyes) were treated with three monthly ranibizumab injections followed by as-needed retreatment. Best-corrected visual acuity (BCVA) and morphological parameters were evaluated over 24 months of follow-up. Results: The mean BCVA in tAMD and PCV patients was significantly improved at 3 months (-0.22 and -0.09 logMAR units, respectively). The improvement in BCVA was sustained up to 24 months in tAMD (p = 0.01) but not in PCV patients. The significant predictor for good response to ranibizumab in tAMD patients was the improvement of BCVA at 3 months, whereas that in PCV patients was the anatomical resolution at 3 months. Conclusions: Ranibizumab is an effective therapy for tAMD and PCV over 24 months. The predictors for good outcome might be different between tAMD and PCV.

Purpose. To evaluate the early response to intravitreal ranibizumab (IVR) in two different phenotypes of age-related macular degenerations (AMD): typical neovascular AMD (tAMD) and polypoidal choroidal vasculopathy (PCV).Methods. Sixty eyes from 60 patients (tAMD 28, PCV 32 eyes) were recruited. Three consecutive IVR treatments (0.5 mg) were performed every month. Change in the best-corrected visual acuity (BCVA) and central retinal thickness (CRT) was then compared between the tAMD and PCV groups.Results. The mean BCVA logMAR was significantly improved at month 1 and month 3 after the initial IVR in the tAMD group, but there was no change in the PCV group. Both phenotypes showed significant improvements in the CRT during the 3 months after the initial IVR. There were no significant differences in the improvements of the CRT in the tAMD versus the PCV group. In the stepwise analysis, a worse pretreatment BCVA and tAMD lesions were significantly beneficial for a greater improvement of BCVA at 3 months after the initial IVR.Conclusions. The phenotype of tAMD showed a significantly better early response to IVR than PCV in terms of BCVA improvement.

Abstract Background Neovascular age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV) are sight-threatening maculopathies with both environmental and genetic risk factors. We have previously shown relative risks posed by genes of the complement pathways to neovascular AMD and PCV. Methods In this study, we investigated the haplotype-tagging single nucleotide polymorphisms (SNPs) in the complement component 5 (C5) gene in 708 unrelated Chinese individuals: 200 neovascular AMD patients, 233 PCV patients and 275 controls. Six tagging SNPs in C5 were genotyped. Univariate single SNP association analysis, haplotype-based association analysis and gene-gene interaction analysis between C5 and other AMD-associated genes were performed. Results The results revealed none of the six tagging SNPs of the C5 gene had a significant association with neovascular AMD or PCV (P > 0.05). We also found insignificant haplotype-based association, and no significant SNP-SNP interaction between C5 and other genes (including C2-CFB-RDBP-SKIV2L, SERPING1, CETP, ABCG1, PGF, ANGPT2, CFH and HTRA1) for neovascular AMD and PCV. Conclusions This study showed no statistical significance in the genetic association of C5 with neovascular AMD or PCV in a Hong Kong Chinese population. Further studies in large samples from different populations are warranted to elucidate the role of C5 in the genetic susceptibility of AMD and PCV.
