Active clinical trials for "Choroidal Neovascularization"

Being short sighted means that vision is blurry when looking at things far away. People with a condition called "pathologic myopia" are short sighted due to problems in the back layer of their eyes, also known as the retina. Some people with pathologic myopia can develop a serious condition called myopic choroidal neovascularization (mCNV). In people with mCNV, new blood vessels grow into the retina. These blood vessels can break, leaking blood or fluid into the retina. This can cause blurry vision or a loss of vision. In this study, researchers will find out more about how well drug aflibercept works and how safe it is in Canadian patients with mCNV. The researchers in this study will review information from the patients' eye doctor visits. The patients in this study will include Canadian men and women who started receiving aflibercept between May 2017 and August 2019. These patients were at least 18 years old and had not received treatment for their mCNV before. The researchers will look at the results of vision tests to find out how well the patients could read from a distance after they received aflibercept for 6 months. They will compare the results of these tests to before the patients received treatment. They will also learn more about how safe it is to have aflibercept injection into the eye.

Retinal blood flow velocity is affected by Bevacizump intravitreal injection. This effect is correlated to treatment success.

The main purpose is to find a better way to predict the timing of treatments given to patients with Wet Age-related macular degeneration using image analysis.

The primary objective: *To measure the difference in the number of Ranibizumab therapies needed in 12 months in the Posterior Vitreous Detachment (PVD) positive and Posterior Vitreous Detachment (PVD) negative group. Secondary Objective: To measure the mean change in visual acuity from Baseline to Month 12. To measure the mean change in central retinal thickness per OCT from Baseline to Month 12

This study will investigate the safety and efficacy of treatment of choroidal neovascularization (CNV) due to age-related macular degeneration (AMD) with a combination of ranibizumab (Lucentis) and verteporfin PDT (Visudyne), as compared with ranibizumab monotherapy.

This study will quantify the intraocular pressure elevation in the immediate time period following intravitreous injection. With more widespread use of intravitreous injections in patients that may require several injections per year, it is important to document the sudden increase in intraocular pressure, including the maximum intraocular pressure and the time required for the intraocular pressure to return to baseline. This data may be useful in stimulating additional studies to evaluate the long term ocular effects of repeated intravitreous injections. We hypothesize that the intraocular pressure increases significantly following intravitreous injection and then returns to baseline during the initial thirty minutes following ranibizumab injection.

The objectives of this study are to investigate the safety and effectiveness of EYLEA.

This was a prospective, case-control study investigating aqueous levels of VEGF and PEDF in eyes with mCNV treated with IVB.

Age-related macular degeneration (AMD) is the chief cause of severe and irreversible loss of vision in developed countries. The prevalence of AMD increases dramatically with age. The early stage (or dry AMD) is associated with minimal visual impairment and is characterized by large drusen and pigmentary abnormalities in the macula. The late stage is a neovascular, exudative form. This so called exudative AMD includes serous or hemorrhagic detachment of retinal pigment epithelium and choroidal neovascularization leading to severe loss of vision (20/200 or worse). Patients with unilateral CNV (choroidal neovascularisation) have a significant risk of CNV developing in the second eye. Choroidal blood flow is of great importance for normal visual function. Several reports have provided evidence suggesting that choroidal blood flow is decreased in subjects with AMD. In late stages of AMD angiogenesis leads to the formation of choroidal neovascularization that can cause severe visual impairment by disrupting normal macular function. The purpose of this evaluation is to investigate a possible link between alterations in choroidal blood flow and the development of CNV and serous detachment in the fellow eye of patients with AMD and unilateral neovascular maculopathy. This longitudinal study may provide important findings with respect to natural history and visual prognosis of patients with neovascularized AMD. Ocular blood flow will be determined by non-invasive methods, including laser Doppler flowmetry and laser interferometry

The objective of this surveillance is to collect information about 1) adverse drug reaction not expected from the LPD (unknown adverse drug reaction), 2) the incidence of adverse drug reactions in this surveillance, and 3) factors considered to affect the safety and/or efficacy of this drug.
