The objective of this study was to compare visual parameters and retinal layers’ morphology pre-treatment (baseline) and 6 months post-treatment in polypoidal choroidal vasculopathy (PCV) eyes. A single centre, longitudinal, prospective study was conducted at a public tertiary hospital of Malaysia. Visual parameters including distance and near visual acuity (DVA and NVA), contrast sensitivity (CS), reading speed (RS), and different qualitative and quantitative optical coherence tomography (OCT) parameters were evaluated pre- and 6 months post-treatment. Thirty-three naïve PCV eyes of 32 patients (mean age of 67.62 years) were evaluated pre- and post-treatment of intravitreal ranibizumab with and without photodynamic therapy. After treatment, sub retinal fluid decreased from 27 eyes (84.35%) at baseline to 7 eyes (21.88%) at 6 months while pigment epithelium detachment decreased from 32 eyes (100%) at base line to 15 eyes (46.87%) at 6 months. Mean pre-treatment quantitative morphological OCT retinal parameters including thickness and volume of central sub field, center thickness, center minimum, and maximum thickness reduced significantly. Similarly, all visual parameters including DVA, NVA, CS, and RS showed statistically significant improvement. While 89% of the eyes showed improvement in CS, 78%, 71%, and 65% of the eyes showed improvement in NVA, RS, and DVA, respectively. Thus, CS was the most treatment responsive visual parameter.

Choroidal Vasculopathy

Purpose: Compare the effect of Combination therapy (PDT+Anti-VEGF) and Anti-VEGF monotherapy on choroidal vascularity indices and morphological parameters in Polypoidal Choroidal Vasculopathy (PCV). Methods: Retrospective, cohort study involving 33eyes with a diagnosis of PCV and had visible sclerochoroidal boundary on enhanced depth imaging. Cases were treated either with combination (n=17) or Anti-VEGF monotherapy (n=16). Demographic details, visual acuity assessment, OCT analysis was considered from baseline to the 3rd and 6th month follow-up visits. Choroidal vascularity analysis including choroidal thickness, Total Choroidal Surface Area (TCSA), Total Stromal area (TSA), Total Luminal Area (TLA) and Choroidal Vascularity Index (CVI) assessment were done with ImageJ software using the technique of image binarization. Results: Disease activity was significantly higher in the Anti-VEGF monotherapy arm compared to the combination therapy arm both at 3 and 6 months. When compared to baseline values, there was statistically significant decrease in choroidal thickness, Double layer sign (DLS) width, TCSA, TSA and TLA (P<0.05) in the combination therapy arm. Whereas, Anti-VEGF monotherapy arm showed an increase in the mean sub foveal choroidal thickness and DLS width at both visits. Complete collapse of PED, reduction in DLS width which was achieved only in combination therapy arm showed significant positive correlation with the resolution of the disease. CVI did not show a statistically significant reduction in both the arms. Conclusion: In view of better outer retinal and choroidal morphological changes and vascular remodelling, our study strongly supports the superiority of combination therapy over Anti-VEGF monotherapy in PCV

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.
