Clinical Trial: Study of Retinal Oxygenation in Central Retinal Vein Occlusion
Study Status: Recruiting
Recruit Status: Recruiting
Study Type: Observational
Official Title: Multicenter Study of Retinal Oxygenation in Central Retinal Vein Occlusion
Brief Summary: The purpose of the study is to test if oxygen saturation in retinal vessels is correlated with clinical parameters, such as visual acuity, central retinal thickness and presence of neovascularization. Retinal oximetry is performed with fundus camera based oximeters. The study will not entail change in treatment of the disease.
Detailed Summary:
Sponsor: University of Iceland
Current Primary Outcome:
- Retinal vessel oxygen saturation [ Time Frame: 12 months ]
- Visual acuity [ Time Frame: 12 months ]
- Central retinal thickness [ Time Frame: 12 months ]
- Presence or absence of ocular neovascularisation [ Time Frame: 12 months ]As determined by gonioscopic examination
