The purpose of the present study was to assess quality of life (QOL) in n-AMD patients seen in a Malaysian public hospital and to further identify visual and demographic factors that may contribute to QOL scores of these patients. Patients with any form of n-AMD in at least one eye were recruited from hospital's ophthalmology department. Bahasa Malaysia version of National Eye Institute Visual function questionnaire-25 (NEI-VFQ-25) was administered to all participants. Demographics, visual functions (VF) including best corrected distance visual acuity (BCDVA), contrast sensitivity (CS), near visual acuity (NVA) and reading speed (RS) were recorded. Eighty-six patients (Malay=26, Indian=23, Chinese=37) aged 52 to 85 years, diagnosed with n-AMD were chosen to participate. Their mean NEI-VFQ composite score (NEI-VFQ CS) was 66.91 ± 13.07. However, no significant difference in NEI-VFQ CS between gender, races and between the two sub groups of n-AMD were observed (p>0.05). NEI-VFQ CS showed a significant association with RS (correlation coefficient (ρ) =0.627), NVA (ρ =-.660), BCDVA (ρ =-.586), CS (ρ =.0.515). A linear model showed that a combination of BCDVA, NVA, CS is accounted for a significant 38 % variability of NEI-VFQ CS (R 2 =0.382, p<0.001). In conclusion, the QOL of Malaysian n-AMD patients were found to be low. Thus, the study results indicated the need of developing necessary management strategies to address this QOL issues in n-AMD patients in Malaysia. Furthermore, the present study suggested incorporating appropriate VF such as near acuity, contrast sensitivity, reading speed in clinical settings while assessing n-AMD patients as these VF explain the patient's perception about the impact of this disease.

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.

Although optical coherence tomography (OCT) parameters have assisted in the diagnosis of polypoidal choroidal vasculopathy (PCV), its potential to evaluate treatment outcomes has not been established. The purpose of this pilot study was to evaluate baseline OCT parameters that may influence treatment outcome in PCV eyes with combination therapy. In this single-centered, prospective study, patients were recruited with at least one treatment-naïve PCV eye and treated with combination therapy of intravitreal anti-vascular endothelial growth factor and photodynamic therapy. Best-corrected distance and near visual acuity (DVA and NVA), and contrast sensitivity (CS) were recorded at baseline and six months after treatment. OCT parameters were determined. Twenty-six eyes of 26 patients aged between 51 to 83 years were evaluated. In eyes that had disrupted external limiting membrane (ELM), photoreceptors inner and outer segment (IS-OS) junction at 1000 micron of fovea at baseline showed low mean visual functions after 6 months of treatment. Eyes with foveal sub-retinal fluid (SRF) and polyp at central 1000 micron of fovea at baseline showed significantly worse DVA and CS after six months. Thus, the presence of foveal SRF, foveal polyp, disrupted ELM, and IS-OS junction at baseline significantly influenced the six months’ visual outcome in PCV eyes treated with combination therapy.
