Filter by:With the improvement of health system, the life span of Asians has increased tremendously especially in Malaysia. As an early preparation to be an 'aging country' in 2023, Malaysia needs to prepare infrastructure and policy to improve quality of life (QoL) in older adults. Glaucoma is an aging related chronic disease that cause progressive optic neuropathy and visual field defect1. The main aim of glaucoma treatment is to slow down disease progression and preserve patient's QoL2. Modification of intraocular (IOP) is believed to be the mainstay of treatment but may not prevent progression of the disease. Modification of lifestyle has been found to change the prognosis of many chronic diseases such as diabetes mellitus. However, there is minimal evidence on the effect of lifestyle modification on glaucoma. Although constricted visual field almost asymptomatic especially in primary open angle glaucoma but many domestic injuries such as fall has been reported. Glaucoma patients reported greatest restriction with mobility especially driving compared to the other domains3,4. Reduction of walking and moderate-to-vigorous physical activity was also found in those with bilateral visual field loss5. Progressive constriction of visual field has been found to increase dependency, reduce mobility, pleasure of reading and QoL of glaucoma patients6. This will lead to psychological and emotional disturbance, in certain cases even resulted in depression. On the other hand, being physically active is found to have some protective effect against development and severity of glaucoma8,9. Thus, identifying problems related to physical activities in constricted visual field is important for improvement of rehabilitation and exercise regime for glaucoma patients. An exercise regime must be effective without causing major changes to IOP, safe in patients with constricted visual field and sensitive to social culture of Malaysians. Addressing these issues will lessen dependency and promotes healthy living among older adults. Improvement in navigation perhaps may increase the physical activities in glaucoma. Reading is another important pleasure in life. Visual field defect in glaucoma patients has been reported to associate with slower reading speed, saccade rate and visual span10,11. Identification of factors associated with difficulty in reading among glaucoma patients and development of rehabilitation regime in reading may improve the happiness index in literate patients. Nevertheless, there is no specific rehabilitation program to improve reading abilities among glaucoma patients. A combination of visual rehabilitation of low vision therapy and occupational therapy is ideal. Although, there is improvement in reading ability and mobility post low visual aid rehabilitation but there is no evidence on glaucoma patients specifically12. Improvement in daily living and dependency may improve their QoL. Happiness perhaps may improve the balance between oxidative stress damage and antioxidant level. Many previous studies discovered that various biomarkers of oxidative stress are elevated in people with depression, and anxiety disorders13. Similarly, oxidative stress has been implicated in pathogenesis of glaucoma and accelerates retinal ganglion cell damage in glaucoma14. Indirectly, improvement of QoL will help in halting the progression of visual field defect. Based on the previous research project on Malays in Malaysia, navigation and mobility has been identified to be mostly affect in primary glaucoma patients based on QoL questionnaires. Physical activities have potential protective effect against progression and severity of glaucoma9. Improvement in navigation, physical activities and reading ability, perhaps may improve their QoL. The main problem is how do we improve their navigation, physical activities and reading ability despite their constricted visual field. The most important step is to understand the problem and issues pertaining to the navigation, physical activities and reading faced by patients with glaucoma.
Trabeculectomy and XEN45 gel stent implantation are glaucoma surgeries that creates an aqueous humor (AH) shunt towards the subconjunctival space (filtration bleb). Once the AH reaches the subconjunctival space, it is removed by different paths such as the trans-bleb wall route. For this reason, the conjunctiva is considered an essential structure that may condition the glaucoma filtering procedures outcomes. As part of the inflammatory response, an unbalanced fibrosis during the postoperative period may lead to a bleb cavity scarring and failure; for this reason, bleb massage and antifibrotic injections (i.e., 5-Fluoruracil) are frequently required as part of the postoperative care of these procedures. There have been described several risk factors, such as intraocular pressure (IOP) lowering medications, previous surgical interventions or ocular surface disease that may predispose to an early failure. These preoperative factors fail to aim to predict the surgical outcomes. However, ocular biomarkers may overcome this limitation. There are promising studies that have analyzed the role of in vivo confocal microscopy (IVCM), anterior-segment optical coherence tomography (AS-OCT) and conjunctival cytology impression as clinical tools that may improve the filtration bleb assessment at a cellular level.
This study is a observational, prospective, case-control, monocentric study. The main objective is to study the polysomnographic characteristics of sleep in glaucomatous and non-glaucomatous subjects, using data collected in the MARS database of CHU Grenoble-Alpes, to compare the total sleep time of glaucomatous and non-glaucomatous subjects, measured during the polysomnographic examination collected in the database. The secondary objectives are the exhaustive characterization of the sleep architecture in glaucomatous and non-glaucomatous subjects, from data collected in the MARS database of the CHU Grenoble-Alpes - Length of sleep period - Time spent in phase 1, 2, 3 and 4 - Micro-alarm clocks index - Time with arterial oxygen saturation less than 90% - Apnea-hypopnea index
Phase IV randomized, double blind, multicenter, parallel group clinical study to evaluate the efficacy of the combined use of Krytantek Ofteno PF® and Gaap Ofteno PF®, both applied every 12 hours, versus the use of Eliptic Ofteno PF® Plus Gaap Ofteno PF®, both applied every 12 hours, in patients with open angle glaucoma or ocular hypertension during 90 days
The purpose of this study is to evaluate the safety and Intraocular pressure lowering effectiveness of the Streamline™ Surgical System.
The purpose of this study is to prospectively analyze changes in macular pigment optical density and dermal carotenoid levels as they relate to visual field function in patients prescribed a macular pigment-containing medical food (Lumega-Z), in combination with a topical carbonic anhydrase inhibitor.
First, to compare safety and effectiveness outcomes for canaloplasty and trabeculotomy using the OMNI Surgical System to implantation of the iStent inject in lowering intraocular pressure (IOP) in pseudophakic eyes with open angle glaucoma (OAG), and second, to compare safety and effectiveness outcomes for canaloplasty alone (using the OMNI Surgical System)to implantation of the iStent Inject in lowering IOP in pseudophakic eyes with OAG.
This study is conducted to document the effect of switching from preserved prostaglandin analogues monotherapy to preservative free tafluprost 0.0015%. The endpoints analyzed are side effect improvement in these patients.
Bleb failure is reduced with Punch trabeculectomy procedure. Wide sclerostomy during surgery is wanted but controllable. This can be done with single securing suture, releasable sutures and topical intraoperative mitomycin-c. Average IOP without fluctuation (risk factor) can protect the optic nerve.
Study to collect effectiveness and safety data after administration of a bimatoprost intracameral implant in patients with open-angle glaucoma (OAG) or ocular hypertension (OHT).
