Active clinical trials for "Ocular Hypertension"

This is a retrospective chart review and will assess changes in IOP after treatment with any fixed combination in patients who previously received monotherapy.

This is an observational study of Lumigan® 0.01% (bimatoprost) treatment in clinical practice for patients with Primary Open Angle Glaucoma (POAG) or Ocular Hypertension (OHT).

This is an observational study in patients with POAG or OHT that will collect data on the use of Lumigan® 0.01% (bimatoprost 0.01% ophthalmic solution) in a routine clinical setting. Patients will be seen at baseline and at a follow-up visit approximately 8-12 weeks after baseline, as per normal clinical practice.

This study will assess angle width in Chinese patients with Open-angle Glaucoma and/or Ocular Hypertension.

The purpose of this study was to monitor iris pigmentation changes over a 5-year period in patients with open-angle glaucoma or ocular hypertension. To be eligible for the study, these individuals must have experienced an iris pigmentation change while previously dosing with TRAVATAN.

The present study attempts to evaluate the potential beneficial effects of a flavonoid, the epigallocatechingallate, on retinal ganglion cell function, evaluated by pattern electroretinogram, in subjects with ocular hypertension or early glaucoma.

This study is designed with the intention to further elucidate the effects of omega-3 fatty acids on intraocular pressure (IOP) and signs/symptoms of dry eye. Prior studies have shown statistically significant lowering of IOP with use of omega-3 fatty acids but have only been performed in animal models. This study will be the first to attempt replication in human models. A limited number of studies have shown an increase in tear production/volume as well as a decrease in the subjective symptoms of dry eye, but more studies are needed to better define these effects. Better understanding of the effects of this supplement on intraocular pressure and dry eye will contribute to the expanding knowledge about the pathophysiology of glaucoma/ocular hypertension and dry eye syndrome and potentially lead to further studies about new potential treatment options for these conditions.

Glaucoma is one of the most prevalent eye diseases and the second most common cause of blindness worldwide. The most common form is primary open angle glaucoma (POAG). Glaucoma is a slowly progressing neuropathy of the optic nerve that causes loss of visual field and eventually blindness. Elevated intra-ocular pressure (IOP) is the most important risk factor. Corticosteroids, which are often used for the treatment of many diseases in ophthalmology and other specialities, may cause an elevation of the IOP. It is estimated that corticosteroids induce ocular hypertension in approximately 18%-36% of the general population and in patients with POAG this percentage can be as high as 92%. When the treatment is sustained, this can cause a glaucomatous neuropathy of the optic nerve (corticosteroid-induced glaucoma). The precise pathogenic mechanism isn't clear yet. Genetic factors are likely to affect the susceptibility to corticosteroid response. Therefore, an overview of the genetic mechanisms of corticosteroid-induced glaucoma can give more insight in the pathogenesis. In this study the researchers investigate the occurrence of SNPs (single nucleotide polymorphisms) in 150 cases with a steroid-response in comparison with 300 controls exposed to corticosteroids without a steroid-response. Up to now, one small GWAS has been conducted comparing 32 patients with and without corticosteroid-induced ocular hypertension after treatment with intravitreal triamcinolone. In this study, two SNPs proximal of the transcriptional start site (near the 5') of HCG22 on chromosome 6 were identified. However, this is a rather small sample population and the investigators didn't match for the underlying disease. Further, in another small study, Hogewind et al. performed SNP analysis in multiple genes (SFRS3, FKBP4, FKBP5, and NR3C1) in corticosteroid-induced ocular hypertension. This study enables the investigators to identify patients at risk for developing corticosteroid-induced glaucoma and to gain a better insight in the pathogenesis. This may also lead to the discovery of biomarkers that indicate an increased risk of developing a steroid-induced glaucoma and new prevention and treatment strategies, which are necessary as the treatment of corticosteroid induced-glaucoma now only focuses at lowering the IOP and can still be challenging.

Glaucoma is a leading cause of blindness worldwide. Intraocular pressure (IOP) remains the only modifiable risk factor for glaucoma. Without sufficient IOP lowering therapy, glaucoma induces retinal ganglion cell death and visual field loss. Pattern electroretinography (pERG) measurements directly correlate with retinal ganglion cell (RGC) signaling, providing an objective, repeatable, and non-invasive assessment of RGC function. The purpose of the study is to investigate the pERG changes associated with acute IOP reduction using the Mercury™ Multi-Pressure Dial (MPD). 10 patients will be enrolled. These subjects will have a best corrected visual acuity of 20/40 or better in both eyes and an established diagnosis of one of either mild/moderate OAG (open-angle glaucoma), OHT (ocular hypertension), or glaucoma suspect. Both eyes will be enrolled in the study. The study eye will receive a standardized 10 mmHg decrease in periorbital pressure via the Mercury™ Multi-Pressure Dial (MPD), and the fellow/control eye will receive no (zero) pressure application. Total google wear time will be 4.5 hours. Serial pERG measurements will be taken before, immediately after, and 2 hours after negative pressure application.

This is a non-interventional, prospective, longitudinal cohort study. A total of 150 pediatric subjects with glaucoma or elevated intraocular pressure, including 75 latanoprost-treated subjects and 75 non-topical prostaglandin analogue treated subjects, will be enrolled from ophthalmic hospital clinics and academic ophthalmic centers. As a non-interventional study, the study subjects' continued use of latanoprost and assessments of ocular events will be obtained through the routine medical follow-up with treating ophthalmologists or other designated members of the medical care team.
