Filter by:This study is designed to verify hypothesis that early vitrectomy may prevent impending macular hole from progression to full-thickness 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.
The purpose of this study is to determine the effect of postoperative posturing on the outcome of macular hole surgery. Current practice is divided; some individuals are advised to posture face-down for 10 days and others are advised that posturing is unnecessary. By evaluating the effect of posturing in a prospective randomised controlled trial the investigators hope to determine best practice, enabling surgeons and patients to make informed decisions regarding postoperative management.
The purpose of this study is to evaluate the role of cataract surgery and cystoid macular edema (CME) on reopening of idiopathic macular holes (IMH).
Macular Hole Surgery with two different Dyes
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 evaluate the anatomical and visual outcomes after vitrectomy and internal limiting membrane (ILM) peeling with indocyanine green (ICG) or trypan blue (TB) for idiopathic macular hole repair in a prospective randomized trial.
The project is a randomized clinical trial with a follow up time of 12 months comparing the effects of surgical treatment of idiopathic macular holes. Patients are randomized to vitrectomy alone, vitrectomy plus indocyanine green (ICG) assisted inner limiting membrane ( ILM) peeling or vitrectomy plus trypan blue (tb) assisted ILM peeling. At baseline patients are characterized using early treatment diabetic retinopathy study (ETDRS) visual charts, tests of aniseikonia, optical coherence tomography 3 (OCT3), visual field and fundus photography. Per- and postoperative complications are registered. Data analyses will help clarify the effect of ILM peeling on hole closure and visual acuity. Comparing results after ICG- and tb assisted ILM peeling will help clarify the topic of a toxic effect on retinal cells after staining and peeling of the ILM. Changes in intraretinal morphology before and after dye-assisted ILM peeling will be studied using OCT3 imaging and the patients' subjective opinion on the surgical results will be analyzed using quality of life questionnaires and metamorphopsia tests.
A macular hole is a fairly common problem in the retina and is an important cause of loss of central vision. The aim of this study is to determine whether, in patients with a stage 2 or 3 full thickness macular hole (FTMH), peeling a very fine, transparent tissue that covers the surface of the retina, called the internal limiting membrane (ILM) during surgery is superior to non-ILM peeling macular hole surgery. The main outcomes are improvement in vision, achievement of macular hole closure, need for re-operation, health related quality of life (HRQOL) and cost effectiveness.
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.
