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.

In early and intermediate age related macular degeneration (ARMD), visual acuity alone has failed to explain the complete variation of vision. The aim of the present study was to determine correlation between different visual functions and retinal morphology in eyes with early and intermediate ARMD. In this single center cross sectional study, patients diagnosed as early or intermediate ARMD in at least one eye were recruited. Visual functions measured were best- corrected distance visual acuity (DVA), near vision acuity (NVA), reading speed (RS), and contrast sensitivity (CS). Parameters such as thickness (RT) and volume (RV) of the retina, outer retinal layer thickness (ORLT) and volume (ORLV), outer nuclear layer thickness (ONLT) and volume (ONLV), retinal pigment epithelium layer-Bruch’s membrane complex thickness (RPET) and volume (RPEV) were assessed employing semi-auto segmentation method of Spectralis optical coherence tomography (OCT). Twenty-six eyes were evaluated. DVA, CS, and RS showed significantly good correlation with RPET, ONLT, and ONLV, whereas NVA showed good correlation with ONLV and RPET. The present study concluded that RS, CS, NVA, and DVA represent the morphological alteration in early stages and should be tested in clinical settings. ONLT, ONLV, and RPET morphological parameters can be employed as important biomarkers in diagnosis of early to intermediate ARMD.

Objective Near visual impairment (VI) is a common disability in an aging population. Near vision is crucial in activity of daily living including reading, smartphone and computer use and meal preparation. This study was conducted to determine the association between near visual acuity (VA) and contrast sensitivity (CS) with activity of daily living (ADL) among visually impaired older adults. Results A total of 208 participants aged  ≥  60 were recruited from the population-based longitudinal study on neuroprotective model for healthy longevity. Habitual near VA and CS were measured using Lighthouse near VA chart and Pelli-Robson CS chart, respectively. Lawton instrumental activities of daily living (IADL) was used to assess ADL. There are 41.8% participants with near visual impairment and 28.7% among them had IADL disability. Independent t test showed significant lower mean IADL score among visually impaired participants [t(206)  =  2.03, p  =  0.04]. IADL score significantly correlated with near VA (r  =   − 0.21, p  =  0.05) but not with CS (r  =   − 0.14, p = 0.21). Near VA (B  =   − 0.44, p  =  0.03) and age (B  =   − 0.07, p  =  0.01) significantly predicted IADL. The findings show poorer VA renders higher IADL disability, which may necessitate interventions to improve ADL among visually impaired older adults.

Polypoidal choroidal vasculopathy (PCV), a subtype of neovascular age-related macular degeneration, requires repeated treatment. The objective of this pilot study was to evaluate and compare vision-targeted quality of life (QOL) at baseline and after 6 months of treatment in patients with PCV. Naive PCV patients were recruited. Visual functions assessed were distance visual acuity (DVA), near visual acuity (NVA), contrast sensitivity (CS), reading speed (RS), and QOL at baseline and after 6 months of treatment. Thirty patients (average age of 67.62 ± 8.05 years) revealed mean DVA and NVA improvements of 0.24 logMAR and 0.30 logMAR, respectively. Mean CS and RS improved by 0.39 log contrast and 25.58 words per minute, respectively. The National Eye Institute Visual Function Questionnaire 25 (NEI-VFQ-25) composite score significantly increased from a baseline of 66.73 ± 13.74 to 73.54 ± 14.26. Twenty-eight of the patients showed overall improvement in QOL score by 5 units or more or remained stable. Subscales of NEI-VFQ-25 significantly improved, with general vision, mental health, and role difficulties improving by 10 or more units. The present pilot study reports a significant improvement of QOL in PCV patients after 6 months of treatment, with mental health, role difficulties, social functioning, and distance vision activities being the most improved subscales.

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.

Illumination is one of the important physical aspects that influences comfortability during learning session particularly among visually impaired students. The purpose of this study was to determine changes in illumination level in classrooms during learning session at Sekolah Menengah Pendidikan Khas (SMPK), Setapak. The second objective was to compare the illumination level in the classrooms under three different lighting conditions: daylight only, with additional artificial light and with removal of obstructions to daylight. Illumination levels in 17 classrooms was measured at one hour interval, between 8 am to 1 pm for the first stage and 19 classrooms under three different lighting conditions from 11 am to 12 noon for the second stage, using ILM1335 (ISO-TECH, Taiwan) digital luxmeter. Illumination level increased significantly from 8 am to 11 am (One-Way Repeated Measures ANOVA: F(2.14, 34.26)=76.49, p<0 .001) and was maximum at 1 pm. The illumination level was highest for the condition of daylight with additional artificial light (One-Way Repeated Measures ANOVA: F(2,34)=110.51, p<0.001) compared to other conditions. Illumination levels for daylight without obstruction was significantly higher than daylight only (pairwise comparison: p=0.001). Classroom illumination level was lowest in the early morning. However, classroom illumination can be increased either by removing the obstructions to daylight or with additional artificial lighting.
