    Purpose: To determine the role of microvascular endothelial dysfunction as risk factor for primary open angle glaucoma.

    Methods: A cross-sectional study was conducted involving 114 Malay patients with POAG seen at the eye clinic of Hospital Universiti Sains Malaysia. Patients aged between 40 and 80 years who were diagnosed with other types of glaucoma, previous glaucoma filtering surgery or other surgeries except uncomplicated cataract surgery and pterygium surgery were excluded. A total of 101 patients who were followed up for dry eyes, age-related cataracts or post cataracts extraction surgery were recruited as control subjects. Those with family history of glaucoma or glaucoma suspect were excluded. Microvascular endothelial function was assessed using laser Doppler fluximetry and the process of iontophoresis. Iontophoresis with acetylcholine (ACh) and sodium nitroprusside (SNP) was used to measure microvascular endothelium-dependent and endothelium-independent vasodilatations, respectively.

    Results: In general, POAG patients demonstrated lower ACh% and AChmax values compared with controls. There was significant difference in microvascular endothelial function [ACh%: mean, 95% confidence interval = 503.1 (378.0, 628.3), and AChmax: mean, 95% confidence interval = 36.8 (30.2, 43.5)] between primary open angle glaucoma cases (p

    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.

    INTRODUCTION: There is limited knowledge on primary angle closure (PAC) in Malays. Understanding the clinical presentation and progression of PAC in Malays is important for prevention of blindness in Southeast Asia.

    MATERIAL AND METHODS: A retrospective record review study was conducted on Malay patients seen in the eye clinic of two tertiary hospitals in Kelantan, Malaysia. Based on the available data, Malay patients re-diagnosed as primary angle closure suspect (PACS), primary angle closure (PAC), and primary angle closure glaucoma (PACG) based on the International Society Geographical Epidemiological classification. Clinical data was collected from initial presentation including the presence of acute primary angle closure until at least 5 years follow up. Progression was defined based on gonioscopic changes, vertical cup to disc ratio (VCDR), intraocular pressure (IOP) and Humphrey visual field (HVF) analysis. Progression and severity of PACG was defined based Hodapp-Parrish-Anderson classification on reliable HVF central 24-2 or 30-2 analysis.

    RESULTS: A total of 100 patients (200 eyes) with at least 5 years follow up were included. 94 eyes (47%) presented with APAC. During initial presentation, 135 eyes (67.5%) were diagnosed with glaucomatous changes with 91 eyes already blind. After 5 years of follow up, 155 eyes (77.5%) progressed. There was 4 times risk of progression in eyes with PAC (p=0.071) and 16 times risk of progression in PACG (p=0.001). Absence of laser peripheral iridotomy was associated with 10 times the risk of progression.

    CONCLUSION: Angle closure is common in Malays. Majority presented with optic neuropathy at the initial presentation and progressed further. Preventive measures including promoting public awareness among Malay population is important to prevent blindness.

    INTRODUCTION: Acute angle closure (AAC) without prompt treatment may lead to optic neuropathy. Environmental factor such as climate change may precipitate pupillary block, the possible mechanism of AAC.

    OBJECTIVE: To determine the association of northeast monsoon and incidence of AAC in Malaysia.

    MATERIALS AND METHODS: A retrospective study was conducted on AAC patients admitted to two main tertiary hospitals in Kelantan, Malaysia between January 2001 and December 2011. The cumulative number of rainy day, amount of rain, mean cloud cover and 24 hours mean humidity at the estimated day of attack were obtained from the Department of Meteorology, Malaysia.

    RESULTS: A total 73 cases of AAC were admitted with mean duration of 4.1SD 2.0 days. More than half have previous history of possibility of AAC. There was higher incidence of AAC during the northeast monsoon (October to March). There was also significant correlation of number of rainy day (r=0.718, p<0.001), amount of rain (r=0.587, p<0.001), cloud cover (r=0.637, p<0.001), mean daily global radiation (r=- 0.596, P<0.001), 24 hours mean temperature (r=-0.298, p=0.015) and 24 hours mean humidity (r=0.508, p<0.001) with cumulative number of admission for AAC for 12 calendar months.

    CONCLUSION: Higher incidence of AAC during northeast monsoon suggested the effect of climate as the potential risk factor. Prompt treatment to arrest pupillary block and reduction of the intraocular pressure is important to prevent potential glaucomatous damage. Public awareness of AAC and accessibility to treatment should be part of preparation to face the effect of northeast monsoon.

    There are limited data in the literature on the optic disc topography in normal tension glaucoma (NTG) patients in Asian countries, especially in Southeast Asia. This study is aimed at comparing optic disc topography in NTG patients and a control group in Malaysia, and we discuss the literature on NTG studies in other Asian populations. A comparative cross-sectional study was conducted in two hospitals with glaucoma services in Malaysia from November 2010 to February 2012. A total of 109 eyes of 109 Malay patients were included in this study: 32 NTG patients and 77 subjects in the control group. All participants underwent a thorough ocular examination, including visual acuity, subjective refraction, anterior segment and fundus examinations, Humphrey visual field 24-2, intraocular pressure measurement, gonioscopy examination and fundus photography. Optic disc topography was assessed using the Heidelberg Retinal Tomograph III by an identified masked investigator in each hospital. NTG patients had a notably larger disc area (2.65 (0.41) vs 2.19 (0.43) mm(2), respectively), larger cupping (1.54 (0.43) vs 0.63 (0.40) mm(2), respectively), smaller retinal rim areas (1.12 (0.41) vs 1.56 (0.33) mm(2), respectively), higher cup volume (0.47 (0.28) vs 0.11 (0.19) mm(3), respectively), reduced rim volume (0.23 (0.13) vs 0.41 (0.16) mm(3), respectively), higher cup to disc area ratio (0.58 (0.14) vs 0.27 (0.15), respectively), higher linear cup to disc ratio (0.76 (0.09) vs 0.49 (0.17) mm(2), respectively), higher mean cup depth (0.37 (0.09) vs 0.22 (0.09) mm, respectively), higher maximum cup depth (0.77 (0.16) vs 0.59 (0.20) mm, respectively), higher mean of cup shape measure (-0.04 (0.06) vs -0.16 (0.07), respectively), and thinner mean retinal nerve fibre layer thickness (0.15 (0.15) vs 0.24 (0.07) mm, respectively) compared to the control group (p<0.05). In conclusion, most of the optic disc parameters were significantly different in NTG patients compared to healthy individuals in Malaysia. Our findings are comparable to those reported in NTG studies in other Asian countries.

    This study reviewed the trabeculectomies (TEs) carried out in University Malaya Medical Center between 1994 to 1998. One hundred and nine of 132 eyes operated were in the primary glaucoma group of which 63 (47.7%) were of the open angle type and 46 (34.8%) were of the angle closure type. Twenty-three eyes belong to the secondary glaucoma group. Sixty-five eyes had plain or non-augmented trabeculectomy (TE) while 20 were augmented with mitomycin C (MMC) and 11 with 5 flourouracil (5FU). In 31 eyes the plain TEs were combined with extracapsular cataract extraction (ECCE) and 4 with phacoemusification. One case had combined ECCE and augmented trabeculectomy with mitomycin-C. The patients were followed up at 1 month, 6 months, 1 year and 2 years. Ninety-four of 132 (71.2%) eyes had successful surgery with intraocular pressure (IOP) of less than 21 mmHg (tonometric success) at the end of 2 years. Four of these patients needed topical medication for the IOP control. More failures were seen in patients with cystic blebs than those with diffuse blebs. Complications include hypotony, shallow anterior chamber, cataracts and hyphaema. The majority of cases (53%) had no complications.

    A cross sectional study was conducted to assess the level of awareness and knowledge of common eye diseases (cataract, glaucoma, diabetic retinopathy and refractive errors) among 473 academic staff (non-medical faculties) of University Malaya. The awareness of cataract was in 88.2%, diabetic retinopathy in 83.5%, refractive errors in 75.3% and glaucoma in 71.5% of the study population. The knowledge about all the above common eye diseases was moderate, except presbyopia which was poor. Multivariate analysis revealed that females, older people, and those having family history of eye diseases were significantly more aware and more knowledgeable about the eye diseases. Health education about eye diseases would be beneficial to seek early treatment and prevent visual impairment in the society.

    Visual impairment among the elderly is a major health problem. With advancing age, the normal function of eye tissues decreases and there is an increased incidence of ocular pathology. Demographic studies have shown that age is the best predictor of blindness and visual impairment. The most common causes of age related visual impairment in the elderly are presbyopia, cataracts, age related macular degeneration, primary open angle glaucoma and diabetic retinopathy. Untreated visual impairment leads to physical handicap, increased incidence of fall, depression, social isolation and dependency. Active screening for visual loss in the elderly should be part of the health examination. The elderly should be encouraged to come for formal 1-2 yearly eye assessment for early detection of visual impairment and to treat all associated problems in order to prevent permanent visual loss.

    OBJECTIVE: To compare the clinical presentation, severity and progression of primary angle closure between Chinese and Malays residing in Malaysia.

    METHODS: A comparative retrospective record review study was conducted involving one hundred (200 eyes) Malay and fifty eight (116 eyes) Chinese patients. They were selected from medical records of Hospital Universiti Sains Malaysia, Kelantan and Hospital Pulau Pinang, Penang, Malaysia. The selected patients were re-diagnosed based on the International Society of Geographical and Epidemiological classification. The clinical data on presentation including the presence of systemic diseases were documented. Progression of the disease was based on available reliable visual fields and optic disc changes of patients who have been on follow-up for at least five years.

    RESULTS: Malay patients presented at older age (61.4 years SD 8.4) compared to Chinese (60.6 years SD 8.3). There was significant higher baseline Intraocular Pressure (IOP) among Malays (34.7 SD 18.5mmHg) compared to Chinese (30.3 SD 16.7mmHg) (p=0.032). The Chinese patients presented with significantly better visual acuity (p<0.001) and less advanced cup to disc changes (p=0.001) compared to Malays. Malay patients progressed faster than the Chinese. Majority progressed within 1 year of diagnosis. Malays without laser peripheral iridotomy (LPI) have a 4 fold (95% CI 1.4, 10.9) risk of progression. Higher baseline IOP, more advanced visual field defect and absence of LPI was identified as significant predictors associated with progression.

    CONCLUSION: The Malays presented with more advanced angle closure glaucoma as compared to the Chinese in Malaysia. Aggressive disease progression was observed in Malays with the onset of optic neuropathy. Effective public awareness and aggressive management is important to prevent blindness in the Malaysian population.

    Thirty-seven consecutive patients (41 eyes) diagnosed with primary angle closure glaucoma (PACG) attending the Glaucoma Clinic in University Malaya Medical Centre, over a period of 6 months were categorized into acute, subacute and chronic PACG from their clinical presentation. Each case was subjected to automated refraction, A-scan biometry for anterior chamber depth, axial length and lens thickness, keratometry and corneal diameter measurement. Calculations for the relative lens position and the lens thickness: axial length index were performed. The data collected was analysed by the nonparametric test (Kruskal-Wallis), one way analysis of variance (ANOVA), chi-square test, Spearman's nonparametric correlations and regression analysis. For controls 15 eyes from 15 normal subjects matched for age, sex, refractive error and race were chosen and subjected to the same examinations. Chronic PACG was the predominant subtype (53.6% of patients and 58.5% of eyes). The ocular biometric measurements of acute PACG eyes deviated most from normals in having the shallowest anterior chamber depth, shortest axial length, smallest corneal diameter, steepest corneal radius, thickest and most anteriorly situated lens, and the greatest lens thickness: axial length index. The subacute subtype was closest to normal and chronic PACG subtype fell in between in most of the biometric characteristics. These findings were not statistically significant. All PACG eyes as a group however showed statistically significant shallower anterior chamber depth (p < 0.05), and a more anterior relative lens position (p < 0.05) compared to normals.

    The records of all the glaucoma patients seen at the General Hospital Kuala Lumpur over a five year period were analysed. The racial, age and sex distribution of patients with primary open angle glaucoma and primary angle closure glaucoma was determined. The causes of secondary glaucoma were analysed. As no previous records of glaucoma statistics are available in Malaysia, it is hoped that these findings will form an initial mosaic to build on in the future.

    A clinical audit was conducted for a 4-year period at the Universiti Kebangsaan Malaysia (UKM) Ophthalmology Department in which 61 eyes of adult patients with primary glaucoma underwent trabeculectomies without antimetabolites. At a 2-year follow-up duration, successful trabeculectomies as defined by intraocular pressure below 20 mm Hg without additional glaucoma medication were 62% for primary open-angle glaucoma, 48% for primary acute angle-closure glaucoma and 43% for chronic angle-closure glaucoma. 50.8% of eyes were without complications while 49.2% had complications. Shallow anterior chamber (22.9%) and hyphaema (19.7%) were the two commonest complications.

    A retrospective study was conducted at the Hospital Sultanah Aminah Johor Bahru to determine the outcome of trabeculectomy surgeries over a period of 4 years. One hundred and two eyes were followed up to a maximum of 63 months (mean 34.2 months). The 2-year survival rates for plain trabeculectomies, 5-Fluorouracil augmented trabeculectomies and Mitomycin-C augmented trabeculectomies were 52.9%, 27.3% and 60.5% respectively. The commonest complications noted were cataract formation (25%) and hyphaema (11%). Mitomycin-C induced complications were rarely seen. At last follow-up, 54% of eyes had intraocular pressures below 21 mmHg without medication, while 34% of eyes had intraocular pressures below 21 mmHg with medication. Vitreous at the trabeculectomy site was a statistically significant predictor of operative failure.

    BACKGROUND: Subliminal transscleral cyclophotocoagulation (SL-TSCPC) is a new alternative therapy to reduce intraocular pressure (IOP) safely and effectively. However, there are few studies regarding SL-TSCPC by Supra 810 laser machine and limited data regarding its effectiveness in moderate severity glaucoma that still has good preservation of vision. This study was conducted to evaluate the outcome of SL-TSPCPC in various types of glaucoma including patients with good vision.

    METHODS: A retrospective, non-comparative, analytical case series of all patients who received SL-TSCPC treatment from October 2018 to April 2019 at Hospital Tengku Ampuan Afzan, Pahang, Malaysia. Data was collected during the second week, sixth week, third month and sixth month follow-up. The primary outcome measure gave success rate at six months post-treatment. Secondary measures were changes in visual acuity, mean IOP reduction, mean number of IOP lowering medications reduced and ocular side effects noted during follow-up.

    RESULTS: The success rate was 43.8% (seven eyes out of sixteen eyes) at six months post-treatment. The mean IOP reduced from 43.0mmHg±14.8mmHg pre-treatment to 24.7mmHg±12.0mmHg at two weeks post treatment with 42.6% reduction. Subsequently, mean IOP at sixth week, third month and sixth month were 33.8mmHg±16.9mmHg, 35.2mmHg±14.9mmHg, and 29.0mmHg±16.2mmHg respectively. Vision maintained in 13 patients, two patients had improvement in vision however, five patients had deterioration in vision. No serious ocular side effects were noted.

    CONCLUSION: Subliminal TSCPC is a safe and alternative method of lowering IOP in moderate to advanced glaucoma over 6 months duration of follow-up. As it has good safety profile and repeatability, it is a good treatment option for patients with uncontrolled glaucoma.

    INTRODUCTION: The aim of this study was to investigate the clinical effectiveness, health related quality of life (HRQoL) and cost effectiveness of selective laser trabeculoplasty (SLT) compared to topical anti-glaucoma medications in step-up treatment of patients with primary open angle glaucoma (POAG).

    METHODS: Seventeen POAG patients with suboptimal IOP control despite pre-existing topical medications were subjected to adjunct SLT (50 applications 180 degrees) or second line medical therapy. Current medications were continued, and patients were followed up for 6 months for degree of intraocular pressure (IOP) lowering. HRQoL was assessed using Glaucoma Quality of Life 36-item (GlauQoL-36), Assessment of Quality of Life-7D (AQoL-7D) and Vision related Quality of Life (VisQoL). Costs involved were calculated and compared to the effect (IOP reduction) achieved in each arm.

    RESULTS: Ten patients were in the SLT group and 7 in the topical medication (MED) group. Mean baseline intraocular pressure (IOP) was 18.90±3.48mmHg in SLT group and 15.57±2.23mmHg in MED group. Mean reduction of IOP was 4.30±1.64mmHg in SLT group and 2.71±2.56 mmHg in MED group at 6 months which was not statistically significant (p=0.14) between two groups. All the HRQoL questionnaires did not show significant changes in the groups or between groups when compared baseline with 6-month post treatment (p-values ranging from 0.247 to 0.987). For every 1mmHg reduction in IOP, cost involved in MED group (RM53.61) was 165% of the cost involved in SLT group (RM32.56).

    DISCUSSION AND CONCLUSION: This study has shown that SLT was as effective clinically and tolerable as topical anti glaucoma medications and was possibly more cost effective in the step-up treatment of patients with POAG at 6 months follow- up.

    The Prostaglandin F2alpha (PGF2alpha) receptor gene has been found to play an important role in reducing the intraocular pressure of the glaucomatous patients. Variations of the PGF2alpha receptor gene may be responsible for the differences in the response to an antiglaucoma drug, Latanoprost. A combined method of denaturing High Performance Liquid Chromatography (dHPLC) and sequencing was applied to detection of the PGF2alpha receptor gene variant among the 76 Malaysian patients with glaucoma, and a novel single nucleotide polymorphism (SNP), IVS -97A>T, was identified. According to the genotyping analysis, 36.8% of the subjects were heterozygous for the variant allele T, while 9.2% homozygous. The frequency of variant allele T was 0.28. Although with a limited number of samples, our data suggested that this polymorphism is common in the Malaysian patients with glaucoma.

    OBJECTIVES: This study aimed to explore the eye drop instillation technique of patients with glaucoma and whether a pharmacist-led counselling session can improve their technique. Patients' perceptions of pharmacists' role in providing the counselling were also explored.

    METHODS: This cross-sectional study was conducted between December 2020 and March 2021 at Sarawak General Hospital, Malaysia. Convenience sampling was used to recruit patients with glaucoma who self-administered their eye drops. Participants' background information were obtained using an investigator-administered questionnaire before their eye drop instillation technique was assessed. Those with imperfect techniques were counselled by a pharmacist before being reassessed. Differences in eye drop instillation competency were determined using paired T-test.

    KEY FINDINGS: A total of 138 participants were recruited. Participants were on a median of two eye drops (IQR 2-4) for a median of five years (IQR 2-8). Prior to being counselled, they demonstrated a mean total of 8.4/13 steps (SD 2.33) correctly. A statistically significant improvement in eye drop instillation technique was observed post-pharmacists' counselling, with a mean increase of 4.3 steps demonstrated correctly (95% CI, 4.0 to 4.7, P < 0.001). The majority of participants agreed that pharmacists are knowledgeable in providing counselling on eye drop administration techniques.

    CONCLUSIONS: Patients with glaucoma treated at Sarawak General Hospital had imperfect eye drop instillation techniques, despite most having used their eye drops for several years. Interventions by pharmacists to improve eye drop instillation are crucial to optimise the medical treatment of patients with glaucoma.
