INTRODUCTION: Glaucoma is a leading cause of permanent blindness, often going undetected in its early, asymptomatic stages, especially in older age groups. In Malaysia, glaucoma is a growing public health issue due to an increase in the ageing population. While screening is essential for early glaucoma detection, the most suitable strategy for Malaysia's healthcare system remains unclear. This study explored the perspectives of eye healthcare professionals on the most suitable glaucoma screening strategies for Malaysia. MATERIAL AND METHODS: This qualitative study used semi-structured interviews with 19 eye health professionals (ophthalmologists, optometrists, nurses, ophthalmic technicians, and assistant medical officers) practicing in the Klang Valley. The interviews were conducted face-to-face in their workplace or via a video conferencing platform. All interviews were recorded, transcribed, and analysed using thematic analysis. RESULTS: Six major themes were identified: types of glaucoma screening programmes, accessible screening locations, target screening population, instruments and use of digital technology, trained personnel, and referral criteria. Opportunistic case finding and population-based programmes were identified as the glaucoma screening programmes in which trained personnel conducted screening at accessible locations. Glaucoma screening for high-risk individuals was recommended, focusing on visual acuity testing, tonometry, anterior chamber angle assessment, funduscopy, perimetry, and retinal nerve fibre assessment. A lack of clear referral criteria due to low awareness and poor implementation of existing guidelines was observed. CONCLUSION: Further investigations are required to identify the best combination of components for glaucoma screening. This will enable policymakers to develop an effective glaucoma screening programme in Malaysia.

Glaukoma adalah sejenis penyakit neurodegeneratif yang berlaku akibat ketidakseimbangan dalam peredaran cecair akues yang disebabkan oleh resistan pada sistem pengaliran keluar cecair tersebut. Ini meningkatkan tekanan intraokular (TIO) yang menyebabkan kerosakan pada saraf optik dan seterusnya mengakibatkan kebutaan yang kekal. Oleh kerana TIO adalah satu faktor risiko glaukoma yang boleh dikawal, ciri-ciri dan variasi tekanan sepanjang 24 jam perlu dikenalpasti sebelum rawatan dimulakan. Pemantauan TIO adalah satu aspek yang terpenting dan kritikal dalam pengurusan glaukoma. Pelbagai tindakan kawalan melalui penggunaan teknologi yang berbeza telah dan sedang dilakukan untuk pemantauan TIO yang kerap dan berterusan selama 24 jam untuk menentukan kewujudan TIO yang tinggi (peak) dan fluktuasi tekanan. Artikel ini bertujuan untuk meninjau pendekatan inovatif yang terkini serta untuk mengulas kepentingan dan kelemahan setiap teknik bagi memperolehi profil TIO selama 24 jam.

Ocular abnormalities have apparent effects on brain activation. However, neuroimaging data about the ocular characteristics of healthy participants are still lacking to be compared with data for patients with ocular pathology. The objective of this multiple participants’ functional magnetic resonance imaging (fMRI) studies was to investigate the brain activation characteristics of healthy participants when they view stimuli of various shapes, pattern and size. During the fMRI scans, the participants view the growing ring, rotating wedge, fl ipping hour glass/bow tie, quadrant arc and full checker board stimuli. All stimuli have elements of black-and-white checkerboard pattern. Statistical parametric mapping (SPM) was used in generating brain activation via fi xed-effects (FFX) and conjunction analyses. The stimuli of various shapes, pattern and size produce different brain activation with more activation concentrated in the left hemisphere. These results are supported by the conjunction analysis which indicated that the left pre-central, post-central, superior temporal and occipital gyrus as well as the left cingulate cortices were involved when the participants viewed each given stimulus. Differential activation analysis showed activation with high specifi city in the occipital region due to the stimuli of various shapes, pattern and size. The activation in the right middle temporal gyrus was found to be signifi cantly higher in response to moving stimuli as compared to stationary stimuli. This confi rms the involvement of the right middle temporal gyrus in the observation of movements. The black-and-white checkerboard stimuli of various shapes, pattern and size, stationary and moving was found to 1) activate visual as well as other cortices in temporal and parietal lobes, 2) cause asymmetry in brain function and 3) exhibit functional integration characteristics in several brain areas.
