Modified Bahasa Malaysia version of VF-14 questionnaire: assessing the impact of glaucoma in rural area of Malaysia.

PURPOSE: To evaluate the functional impairment of glaucoma patients, using a modified Bahasa Malaysia version of VF-14 questionnaire, and to correlate the score with the severity of the disease. METHODS: One-to-one interview by trained interviewers was conducted on glaucoma patients seen in the eye clinic of Hospital Universiti Sains Malaysia, using a modified validated Bahasa Malaysia version of VF-14 questionnaire. The severity of glaucoma was determined based on the better-eye Advanced Glaucoma Intervention Study Scale (AGIS) score of visual field analysis on the latest most reliable visual field. The literacy rate, living situation, better-eye visual acuity and lens status were also documented. RESULTS: A total of 110 glaucoma patients were recruited (54.5% primary open-angle glaucoma, 21.8% primary angle-closure glaucoma, 19.2% normotensive glaucoma and 4.5% pseudoexfoliative glaucoma) and majority with bilateral involvement. Based on the better-eye AGIS score, 41.5% were in advanced stage, 29.1% moderate and 29.1% mild. There was a significant association between VF-14 scoring with the better-eye AGIS score (r =-0. 579, P < 0.001), age (r = -0.313, P = 0.000) and better-eye visual acuity (r = -0.752, P = 0.000). Based on the multivariate analysis, there was a significant association of the questionnaire score and better-eye AGIS score (P < 0.001). CONCLUSION: The Bahasa Malaysia version of modified VF-14 questionnaire is a useful tool in quantifying quality of life among glaucoma patients in rural area with high illiteracy rate and provides moderate correlation with severity of the disease. Customization of quality of life questionnaire according to custom and culture of the community will provide better insight to the functional impairment of glaucoma patients.

Evaluation of Ocular Surface Disease in Asian Patients with Primary Angle Closure.

OBJECTIVE: To evaluate the incidence of ocular surface disease (OSD) and to determine the effects of topical pressure-lowering drugs on ocular surface disease in primary angle closure patients. METHODS: This was a cross-sectional comparative study comparing primary angle closure glaucoma (PACG) patients (Group A) with primary angle closure and primary angle closure suspect (Group B). Group A was treated with topical pressure-lowering drugs; Group B was not. Data on ocular diagnosis and details of treatment were obtained from medical records. Ocular surface disease incidence was assessed using the Ocular Surface Disease Index (OSDI) questionnaire and from clinical signs using Schirmer's test, tear break-up time and corneal fluorescein stain. Predictive Analytic Software 20 and STATA analysis software were used for statistical analyses. RESULTS: Group A demonstrated a higher rate of OSD (OSDI 52.3%, Schirmer's test 70.5%, tear break-up time (TBUT) 75%, corneal staining 77.3%) compared to Group B (OSDI 39.0%, Schirmer's test 73.2%, TBUT 58.5% and cornea staining 14.6%) except for Schirmer's test. There was a significant difference in mean score of OSDI (p=0.004), TBUT (p=0.008) and cornea staining (p<0.001) between two groups. Primary angle closure glaucoma treated with more than two medications and for more than three years had worse ocular surface disease parameters but without statistical significant difference. CONCLUSION: Ocular surface disease is common in PACG patients treated with topical pressure-lowering drugs. Topical pressure-lowering drugs caused significant OSD symptoms and signs except for tear production in PACG patients. Thorough evaluation of ocular surface disease is important to ensure appropriate treatment and intervention in PACG patients.
