Glaucoma is a major cause of blindness. The inability to predict a patient's IOP response to medications is a critical barrier for the clinician to consistently provide highly effective IOP-based treatments. Current trial-and-error approaches to glaucoma management are inefficient and have not addressed this barrier as there are no predictive factors for drug response. Our long-term goal is to improve outcomes by identifying biomarkers and environmental factors that profile a patient at risk for glaucoma by age-of-onset, rate of disease progression, "poor response" to treatment, and large IOP fluctuation. Our purpose of this research project is to address this critical barrier by focusing on physiological factors that predict IOP response to drugs.
Mobility refers to a person's purposeful movement through the environment from one place to another and can be conceptualized as a continuum from bed bound (immobility) on one extreme to making excursions to distant locations on the other extreme. Primary open-angle glaucoma (POAG) is a chronic, progressive optic neuropathy that can lead to gradual loss of vision in the peripheral field and central vision. Older adults with POAG have an increased risk for motor vehicle collisions and falls. Moreover, existing studies suggest that patients with POAG exhibit more postural sway while standing as measured by a balance platform and also tend to walk more slowly than those who are normally sighted and free of ocular disease. While these disturbances likely influence mobility, there has been little research directly assessing the impact of POAG on mobility. This study will assess the impact of POAG on life space (one aspect of mobility) and will determine whether difficulties with life space are associated with difficulties experienced under conditions of dim lighting.
To evaluate glaucoma patients' response to treatment with Xiidra, an FDA-approved drug for ocular surface discomfort, which will be prescribed as standard of care treatment.
Glaucoma is the most common threat to vision rehabilitation in patients with Boston keratoprosthesis type 1 (KPro) implantation. High intraocular pressure (IOP) is the most important risk factor for glaucoma and may lead to irreversible retinal and optic nerve damage. Glaucoma drainage device (GDD) surgery is used to divert aqueous humor (AH) from the anterior chamber to an external reservoir to regulate flow and decrease the IOP. The AH is in direct communication with any corneal damage or surgery undertaken in the anterior chamber and can serve as a source of potential biomarkers to detect early inflammatory or glaucomatous changes. Tears are also one of the most accessible and non-invasive source of biomarkers, especially in Kpro eyes where the central optic allows communication between aqueous humor and the tears at the surface of the eye. The investigators propose to test the hypothesis that distinct inflammatory mediators in the AH and tears can serve as biomarkers for glaucoma development and progression after CT, making them specifically amenable to targeted treatment strategies to minimize vision loss.
Primary Open Angle Glaucoma (POAG) is an eye disease that causes optic nerve damage, visual field defect, and blindness caused by increased intraocular pressure. In recent years, many studies have shown that ginkgo biloba extract has a protective effect on the visual function of glaucoma patients. Studies have shown that Ginkgo biloba capsules can improve the visual field damage of glaucoma controlled by intraocular pressure;Ginkgo biloba capsule can promote the recovery of visual evoked potential of glaucoma controlled by intraocular pressure; the improvement of visual field has a certain correlation with visual electrophysiological recovery. The mechanism may be achieved by suppressing the influx of calcium ions and thereby inhibiting the apoptosis of cells. Therefore, in this clinical study, effect of Ginkgo biloba capsule on visual function of primary open-angle glaucoma with blood stasis syndrome was evaluated by placebo as control.
Traditional ciliary body photocoagulation treatment uses the photocoagulation of long-wavelength laser to destroy the ciliary body tissue that can produce aqueous humor. Therefore, it is a kind of palliative treatment which has proved efficacy but causes great pain to patients. The "ultrasonic glaucoma treatment instrument" produced by French EYE TECH CARE company is referred to as EyeOP1. It uses high-intensity focused ultrasound technique to make target part of the ciliary coagulative necrosis, reduce the production of aqueous humor and thereby lower the intraocular pressure. EyeOP1 is ergonomic and suitable for the human eye, making the treatment process more accurate, simple and fast.
Currently, whether and when intraocular pressure (IOP) lowering medication should be used in glaucoma suspects with high myopia (HM) is still a dilemma. Randomized trials are required to evaluate whether IOP lowering influences the incidence of glaucoma suspect progression in HM eyes.
This is a multiple site, randomized study that will assess the effects of personalized eHealth education and motivational-interviewing-based counseling on patient adherence to physician follow-up appointments.
