Filter by: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.
A study of non-inferiority design comparing brilliant blue and indocyanine green as intraoperative dye in macular pucker and macular hole.
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.
The purpose of this study is to compare the newly released Spectral OCT/SLO (OTI, Toronto, Canada) with the Zeiss Stratus OCT (Carl-Zeiss Meditec, Dublin, CA) with regards to the quality of the images obtained as well as the ease of use.
The purpose of this trial is to compare the ability of two doses of OT-551 ophthalmic solution and drug-free solution to safely and effectively prevent or delay the progression of nuclear cataracts that frequently develop as a result of vitrectomy (surgery for retina repair), thereby avoiding the need for a second surgery (cataract removal). Victrectomies involve removal of the jelly-like substance (vitreous) that is located in a cavity behind the lens.
Rational of the study: for macular holes larger than 400 µm the rate of failure is of more than 20%. It is for these eyes that it is necessary to show the benefit of internal limiting membrane (ILM) peeling in term of vision and success rate. In order to test the benefit of this gesture, it is necessary to make a randomized study. Primary objective: To show that the percentage of success (anatomical closing, confirmed by OCT) at third postoperative month is higher in the ILM peeling group. Design of the study: Randomized multicentric study, in parallel groups, with individual benefit for the patient. Tested Hypothesis: The success rate of the surgery of idiopathic macular holes larger than 400 µm is increased by the peeling of the MLI. Awaited results: To show that the success rate of the surgery of idiopathic macular holes larger than 400 µm is improved by ILM peeling. This category could then have a success rate similar to the small holes. If this difference is not proven, it will remain no justification to continue this procedure which represents little risk but which is not either without consequence.
