Filter by:Glaucoma is a progressive disease resulting in blindness. Determining the onset of the disease is critical so patients may obtain treatment to preserve useful vision. This study will collect data from a population of glaucoma suspects (with positive factors for the disease but with normal vision) along with a population of age matched controls using the pattern electroretinogram (PERG) and other standard eye tests for glaucoma. The PERG measures the function of retinal ganglion cells (RGCs) which come together to form the optic nerve. RGCs may become dysfunctional before dying. The Continuous loop deconvolution technique (CLAD) will be used to extract transient PERG responses in both glaucoma suspects and age matched controls. All patients will be monitored with PERG, Optic Coherence Tomography (OCT) and other ancillary tests over 2 years. CLAD will be compared with conventional techniques of monitoring glaucoma (standard PERG, OCT, visual field etc) to see if the CLAD is better at distinguishing between glaucoma suspects and controls.
Currently, whether and when intraocular pressure (IOP) lowering medication should be used in progressive high myopia (HM) to control axial elongation is still a dilemma. Randomized trials are required to evaluate whether IOP lowering influences the growth of axial length in progressive HM eyes.
In this study, participants will be imaged using two Optical Coherence Tomography (OCT) devices: device N, a standard conventional OCT device with an invention (comfortable chin and forehead rest that can be adjusted to fit each individual's size) attached to the device; and device C, the standard conventional OCT device with no invention attached. The investigators will assess whether the chin and forehead rest attachment (invention) provides a more comfortable experience for patients.
selective alpha-2 receptor agonists cause changes in intraocular pressure and pupillary size thus may affect patient quality of life.
Monitoring the intraocular pressure (IOP) is one of the most important tests used in follow-up among glaucoma suspects and confirmed glaucomatous patients.
To assess intraocular pressure changes among glaucoma patients on systemic antihypertensive and antihistaminic drugs.
This study is for patients have been using prostaglandin analogue eye drops with a preservative for 3 months or more and have been diagnosed with prostaglandin-associated peri-orbital disease. the investigators would like to confirm the real world evidence(RWE) of safety and efficacy after changing to Eybelis ophthalmic solution 0.002%.
Goldmann Applanation Tonometry (GAT) is considered the clinical gold standard for eye pressure measurements and yet it is known to be a subjective measurement with limited repeatability and limited portability. The purpose of this study is to develop an automated and objective method for performing applanation tonometry using standard ophthalmic equipment as well as using 2 portable prototypes.
Clinical, cross-sectional and prospective study to assess the images of the posterior pole of the retina of patients from the Glaucoma Unit of the IOBA and the Hospital Clínico Universitario de Valladolid during the period between May and December 2021. The aim of the project is to provide a sufficient number of images from posterior pole retinographies in patients with suspected glaucoma or with diagnosis of glaucoma in order to determine the sensitivity and specificity of an automatic glaucoma screening algorithm developed by the company Transmural Biotech S.L.
The objective of this study is to develop and test the psychometric properties of a self-report questionaire, the Glaucoma Visual Functioning Questionnaire-40 (GVFQ-40), which was designed to measure the difficulty of daily activities of glaucoma patients and evaluate the effectiveness of clinical treatment or rehabilitation interventions.
