Filter by:To conduct a precision study to assess the microperimetry function of the Spectral OCT/SLO. The study will assess variability across measurements taken by three different operator-device configuration across clinical sites, variability between subjects within a given operator-device configuration, and variability within a subject for a single operator-device configuration.
Macular hole is a hole formation which takes place in the center of the retina. Such a hole needs surgical steps in order to close. Closure of the macular hole will lead to a substantially improvement of vision in most cases. Following macular hole surgery a tamponade of intraocular gas is normally injected in order to keep the macula dry for the postoperative period. Postoperative face down position for a week was earlier standard. Several authors report of good closure rates with both air tamponade or lack of face down positioning. In this study standard pars plana vitrectomy with peeling of the internal limiting membrane (ILM) will be performed. The gas tamponade will be replaced by air. Postoperative face down positioning will not be used.
The aim of this study is to test the efficacy of the combination of dye Lutein, Zeaxanthin and brilliant blue to stain the internal limiting membrane as well as the epiretinal membranes during the Vitrectomy surgery.
The purpose of this study is to compare the anatomical and visual recovery of eyes with traumatic macular hole (TMH) following either early vitrectomy or 6-month observation.
The aim of this study is to determine the condition to detect the status of a macular hole by spectral domain optical coherence tomography (SD-OCT) in gas-filled eyes. The macular area is scanned by SD-OCT (OCT-4000, Carl Zeiss Meditec) in the patients who underwent vitreous surgery for macular hole to detect macular jole closure on postoperative days 1, 3, 7, and 30.
The purpose of this study is to see if glaucoma eye drops (dorzolamide-timolol) have any effect on the duration of an intraocular gas bubble following pars plana vitrectomy.
This observational study investigates the effects of epimacular membrane peeling on the structure and function of the retina.
The purpose of this study is to compare functional and anatomical results of a combined surgery and two time surgery for macular hole and cataract extraction in one hundred and twenty patients (120 eyes) with idiopathic Macular Hole (MH) and cataract in two academic centers.
Macular hole in proliferative diabetic retinopathy with fibrovascular proliferation may have unique features. Internal limiting membrane peeling facilitates hole closure only in cases with shallow macular detachment. Final vision is associated with preoperative visual acuity and degree of macula elevation.
To compare possible toxicities of membrane blue and infracyanine green in vivo by macular function and peripheral visual field.
