Filter by:The investigators are conducting a 5-year prospective, cluster-randomized controlled trial, funded by the Centers for Disease Control (CDC), which provides vision screenings to underserved, vulnerable New York City residents living in affordable housing buildings in Harlem and Washington Heights.
Primary angle closure diseases (PACD) are commonly seen in Asia. In clinical practice, gonioscopy is the gold standard for angle width classification in PACD patietns. However, gonioscopy is a contact examination and needs a long learning curve. Anterior segment optical coherence tomography (AS-OCT) is a non-contact test which can obtain three dimensional images of the anterior segment within seconds. Therefore, the investigators designed the study to verify if AS-OCT based deep learning algorithm is able to detect the PACD subjects diagnosed by gonioscopy.
This is a multi-centre, open label, interventional, comparative, phase I study to identify a safe and efficacious dose (within the range of 14.7mcg to 35.5 mcg) of PA5108 (PolyActiva product code) Latanoprost free acid (FA) sustained release (SR) Ocular Implant in adults who have Primary Open Angle Glaucoma.
PURPOSE: Glaucoma is the leading cause of non-curable blindness globally. Patients with glaucoma will get a gradual narrowing of the visual fields caused by compression at the optic nerve head due to increased intraocular pressure. Thus the main preventive strategy is to reduce intraocular pressure, initially by eye drops and/or laser treatment but in some patients surgery is warranted. The surgical procedure (trabeculectomy) most widely performed worldwide creates a path from the anterior chamber to the subconjunctival space and thereby lowers the IOP by producing a more efficient drainage of the aqueous humour. Surgical success depends upon controlling post-operative inflammation to ensure a functional drainage. The purpose of this blinded, randomized study is to investigate which anti-inflammatory treatment provides better long-term control of intra-ocular pressure (IOP) following glaucoma surgery (trabeculectomy) by comparing topical NSAIDs to topical steroids. Additionally, we want to explore the mechanisms behind the pathophysiology of glaucoma by evaluating retinal and optic nerve head perfusion before and after IOP lowering surgery. The primary outcome is the intraocular pressure 12 months after surgery measured by applanation tonometry. MAIN HYPOTHESIS: - NSAIDs and steroids are equally effective in assuring long-term filtering function and controlling IOP after trabeculectomy but may be associated with different risk profiles and bleb morphology - Patients with lower post-operative IOP demonstrate less progression of visual field loss - Trabeculectomy lowers IOP and provides better microcirculation in and oxygenation of inner retinal layers (i.e. ganglion cell layer) and the optic nerve head
To measure the efficacy and safety outcomes of SLT performed by optometrists.
The standard surgical treatment for glaucoma is trabeculectomy. The PRESERFLO™ (formerly InnFocus) Microshunt (IMS) is a new, minimally invasive drainage device which has been suggested to result in similar IOP lowering, but with faster visual recovery and less complications and postoperative interventions. The objective of this study is to aid in deciding on the use of the IMS in glaucoma surgery by assessing its efficacy and cost-effectiveness in patients with primary open angle glaucoma (POAG) compared to the standard trabeculectomy (TE).
The ophthalmic changes during long-lasting sleep apnea are lacking in description and assessment. The investigators intend to observe patients for a long time and observe if the changes in eye tissues are progressing over the years in easily recognizable patterns.
To evaluate the efficacy of postoperative management with 5-fluorouracil injections after XEN Gel Stent implantation.
To determine the safety and efficacy of Kahook dual blade over Trabectome in lowering intraocular pressure in glaucoma patients. Glaucoma surgery will be performed in conjunction with cataract surgery. The investigators hypothesize that the Kahook dual blade is as effective as Trabectome in lowering intra-ocular pressure (IOP), and as safe with a similar rate of post-operative complications such as hyphema.
This study evaluates the duration of intraocular pressure (IOP)-lowering effect and safety of as needed administrations of Bimatoprost sustained release (SR) in participants with open-angle glaucoma (OAG) or ocular hypertension (OHT) who are not adequately managed with topical IOP-lowering medication for reasons other than medication efficacy.
