Brief Summary:
This study intends to conduct visual function examinations and follow-ups on two groups of glaucoma patients one receiving visual perceptual training and the other serving as a control without training The aim of this study is to explore the effects of visual perceptual training based on the lateral masking paradigm on patients visual function Additionally synchronized EEG-fNIRS signals will be collected to investigate whether changes in patients visual function are accompanied by corresponding alterations in brain function
Detailed Description:
Glaucoma is a chronic eye disease that causes irreversible damage to the optic nerve and can lead to severe vision loss and blindness In China the blindness rate among glaucoma patients is 227 accounting for 88 of the total blind population Among individuals aged 40 and above in urban and rural areas of China approximately 92 million suffer from glaucoma with 55 experiencing blindness in at least one eye and 181 experiencing blindness in both eyes 12 Glaucoma patients may experience severe impairment in visual function leading to significant limitations in vision-related activities such as mobility and visual searching This has a negative impact on the quality of life QOL of patients increasing the burden on individuals families and society
Vision Rehabilitation VR is an integral component of the eye care continuum spanning from diagnosis to treatment and rehabilitation 3 It aims to assist visually impaired patients in maximizing their remaining vision facilitating easier performance of daily activities promoting independence and enhancing quality of life QOL However for glaucoma patients with visual field defects traditional methods such as inverted telescopes and prism glasses are plagued by shortcomings such as unattractive appearance bulkiness blurred visual quality and challenges in adaptation
Perceptual Learning PL is a novel rehabilitation approach aimed at enhancing visual performance through intensified practice of visual tasks Many studies have shown that visual perceptual training can improve visual function in patients with different types of amblyopia or presbyopia as the nervous system exhibits significant neuroplasticity 4-6 However there is limited research on visual perceptual training in visual rehabilitation for glaucoma
Therefore this study intends to conduct visual function examinations and follow-ups on two groups of glaucoma patients one receiving visual perceptual training and the other serving as a control without training The aim of this study is to explore the effects of visual perceptual training based on the lateral masking paradigm on patients visual function Additionally synchronized EEG-fNIRS signals will be collected to investigate whether changes in patients visual function are accompanied by corresponding alterations in brain function
