Filter by:To evaluate the long term safety of repeat dose OTX-TP, a sustained release travoprost drug product, placed in the canaliculus of the eyelid in the treatment of subjects with open-angle glaucoma or ocular hypertension.
To measure the efficacy and safety outcomes of SLT performed by optometrists.
This is an open-label trial of 20 study participants with glaucoma or ocular hypertension. Participants with qualifying study eye(s) after screening and baseline evaluations will receive the Balance Goggles System. After a baseline evaluation (prior to negative pressure application through the BGS), study eyes will be treated for one hour in the clinic and be evaluated again. They will then use the BGS for the next 3-6 weeks and be evaluated again. The goal is to determine whether the intraocular pressure (IOP)-lowering effects of BGS is accompanied by changes in retinal thickness measured by optical coherence tomography (OCT), retinal vascular density measured by OCT-angiography, or retinal fluorescence measured by a fundus camera.
While elevated intraocular pressure (IOP) is no longer part of the definition of glaucoma it remains the sole proven modifiable risk factor for the onset and progression of glaucoma. IOP is known to vary with the time of day as well as with daily activities. The importance of the nycthemeral IOP pattern for successful management of glaucoma has been well documented, especially for patients who experience visual loss despite apparently normal and/or controlled IOP during office hours. The current way of assessing nycthemeral IOP fluctuation is to perform repeated discrete tonometry measurements, once per hour in the best cases. Since its development in the 50s, Goldmann applanation tonometry (GAT) has remained the gold standard method for measuring IOP, despite its limitations. However, tonometry may be an imperfect method for measuring changes in IOP because it allows only snapshot and non-continuous measurements, it is not physiologic and disturbs the sleep architecture. There have been many efforts in the past decades to search for an ambulatory and frequent method to monitor IOP for 24 hours. In this context, Sensimed AG has recently developed a sensing contact lens-based device intended to measure IOP over 24 hours, the Goldfish (GF). First-in-man data obtained with this device showed agreements between IOP measured by GF and values obtained by standard tonometry in the same eye, comparable to literature results for routinely used tonometry devices. However, this pilot study included 9 subjects only with improvable safety, tolerability and efficacy profiles. The main goal of this study is to assess IOP measurements with the GF and compare the values with those obtained by standard tonometry in patients with open angle glaucoma (OAG) and ocular hypertension (OHT).

Combined cataract + trabectome surgery is a surgery designed to help lower the intraocular pressure (pressure in the eye) and hopefully reduce the need for topical drops, progression of glaucoma, and/or further glaucoma surgeries. The purpose of this study is to assess whether using pilocarpine, a medication which is FDA approved to induce miosis, (in other words cause the pupil to constrict or become smaller) provides additional benefit to the success of Trabectome and cataract surgery.
Early glaucomatous visual field changes can be missed with the routinely used Standard Automated Perimetry (SAP) and the 24-2 test pattern due to limited sampling of the central 10 degrees. While this shortcoming can be overcome with the addition of a 10-2 test, performing both tests places extra demand on the perimetric services (doubling test times) and patients. Smart Supra Perimetry (SSP) uses a new faster algorithm that can complete both 24-2 and 10-2 test patterns in a similar time frame to a single 24-2 SAP test. This comparative study aims to determine the sensitivity and specificity (i.e. diagnostic accuracy) of SSP in identifying early glaucomatous visual field loss. A sample of 100 patients with early/suspect glaucoma will undergo SAP 24-2 and 10-2 (SITA algorithm) using Humphrey visual field perimetry and SSP 24+10-2 using Henson 9000. Eyes will be categorised into 2 groups i.e., glaucoma and non-glaucoma, on the basis of structural changes to the disc as evaluated by the clinician. The sensitivity and specificity of the SAP and SSP tests will be established along with test duration. The size and location of defects established with both the SAP and SSP strategies will also be compared.
Correct measurement of the intraocular pressure of children with glaucoma or suspected glaucoma is essential for diagnosis and therapy. Despite new non-invasive measurement methods most of the children are uncooperative during the ophthalmological examination. Therefore examination under anaesthesia is needed. A lot of perioperative factors influence the measurement of intraocular pressure. Established and safe anaesthetic regimes have been modified regarding these factors. Aim of the study is to evaluate, if a standardized anaesthetic protocol generates reliable and reproducible measured values.
The objectives of this study are: - To evaluate the efficacy of Phentolamine Mesylate to lower intra-ocular pressure (IOP) in the treatment of Open-Angle Glaucoma (OAG) and Ocular Hypertension (OHT). - To evaluate the ocular and systemic safety of Phentolamine Mesylate compared to its vehicle. - To evaluate additional efficacy of Phentolamine Mesylate to improve visual performance.
The purpose of this research study is to compare the effect of Latanoprostene Bunod and Timolol on eye pressure and blood vessels of the back of the eye.
