Filter by:This study is to evaluate the efficacy and safety of Combigan ophthalmic solution in combination with Latanoprost when the therapy is swiched from Latanoprost monotherapy in patient with Glaucoma or ocular hypertension. Hypothesis: 1. Combigan Ophthalmic Solution provides addition IOP loweringwhen combined with Latanoprost. 2. The treatment with Combigan Ophthalmic Solution has an acceptable safety profile, as measured by ocular and systemic safety parameters.
With patient education, the compliance with glaucoma medications will increase.
The purpose of this study is to evaluate the safety and efficacy of the iStent trabecular micro-bypass stent in reducing intraocular pressure (IOP) in subjects with open-angle glaucoma.
It is suggested the pathogenesis of normal-tension glaucoma (NTG) involves vascular dysregulation. In the past studies, it is well documented that many physical problems related to vascular dysregulation, such as angina pectoris (Friedman M et al 1974; Russek HI et al 1976), migraine (Diener HC et al 1994), primary Raynaud's disease (Wagner HH et al 1993) and stroke (Gainotti G, et al, 2001; Hayee Ma et al 2001), are associated with a high risk of depressive illness. So, NTG, being a disease involving vascular dysregulation, is postulated to be associated with psychopathology. Glaucoma increases after 40 year-old and the number of people over this age in Hong Kong is rapidly growing. However, we have no knowledge about the link between psychopathology and NTG in Hong Kong. The present study is sought to overcome the limitation in previous research and the goals of present study are: - To identify the prevalence of psychopathology of normal-tension glaucoma Hong Kong Chinese Out-patients attending a university-affiliated glaucoma clinic. - To determine whether there are any differences among NTG patients, patients with glaucoma other than NTG and control in terms of psychopathology and quality of life. Designs: Case-control study to compare among patients with normal-tension glaucoma (NTG), patients with glaucoma other than normal-tension glaucoma (OTNTG) and control in terms of psychopathology and quality of life
The objective of this research program is to improve diagnosis and treatment monitoring of ophthalmic disease by improving diagnostic ultrasound techniques. The program explores the use of novel signal and imaging processing techniques towards this end.
To compare the long-term effect of treating newly diagnosed open-angle glaucoma with standard medical treatment versus filtration surgery.
To assess the long-range outcomes of sequences of interventions involving trabeculectomy and argon laser trabeculoplasty in eyes that have failed initial medical treatment for glaucoma.
The primary purpose is to compare the effect of immediate therapy to lower the intraocular pressure (IOP) versus late or no treatment on the progression of newly detected open-angle glaucoma, as measured by increasing visual field loss and/or optic disc changes. The secondary purposes are to determine the extent of IOP reduction attained by treatment, to explore factors that may influence glaucoma progression, and to describe the natural history of newly detected glaucoma.
