Filter by:Patients with idiopathic macular holes (MHs) postoperative closure rates for large MHs (diameter > 550 μm) are disappointing and often require a second intervention, different techniques have been described with very variable success rates in different published studies, an efficient technique with good functional outcome has not been found.
This study retrospectively analyzed the relationship between the preoperative optical coherence tomography(OCT) and optical coherence tomography angiography(OCTA) software related parameters of patients with idiopathic macular hole, the patient's own clinical data and the best corrected visual acuity (BCVA) for at least one month after surgery.
A prospective randomised study comparing the near visual acuity outcomes using Salzburg Reading Desk in pseudophakic patients with idiopathic full-thickness macular hole treated with pars plana vitrectomy with internal limiting membrane peeling versus inverted flap technique. The aim of the study is confirm or disprove the hypothesis, that the near visual acuity results of pars plana vitrectomy with inverted flap technique for idiopathic macular hole are not inferior to pars plana vitrectomy with complete internal limiting membrane peeling technique. Patients will be followed for 6 months after the operation and near best corrected visual acuity testing on Salzburg reading desk, distance best corrected visual acuity on ETDRS tables and microperimetry will be performed and compared between both groups. Also the macular hole closure rate and complication rate will be compared between both groups.
The aim of the protocol is to compare the ocular outcomes after spontaneous vitreous hemorrhage treated with an early vitrectomy versus ultrasound monitoring with late vitrectomy. The hypothesis is that an early vitrectomy could decrease the rate of retinal detachment occurring after a spontaneous vitreous hemorrhage.
Primary outcome: difference of microperimetry retinal sensitivity after primary vitrectomy for idiopathic full thickness macular holes with inverted flap technique versus internal limiting membrane (ILM) peeling technique Secondary outcomes: difference of visual change after primary vitrectomy for idiopathic full thickness macular holes with inverted flap technique versus internal limiting membrane (ILM) peeling technique; difference in closure rate after primary vitrectomy for idiopathic full thickness macular holes with inverted flap technique versus internal limiting membrane (ILM) peeling technique
Report efficiency and clinical outcomes using 25-gauge, bevel-tip, 20000 cut per minute vitrectomy probe among eyes with various vitreo-retinal diseases
To report closure rate, Best Corrected Visual Acuity (BCVA), Retinal Sensitivity (RS) and Fixation Stability (FS) of idiopathic Macular Holes (MH) randomized to Cover Group (CG) or Fill Group (FG) of the Inverted Internal Limiting Membrane (ILM) flap surgical procedure.
This study compares the anatomical and visual outcomes in a large series of patients affected by idiopathic macular holes larger than 400 µm treated using pars plana vitrectomy and gas tamponade combined with internal limiting membrane (ILM) peeling or the inverted internal limiting membrane flap technique. A part of the participants will receive internal limiting membrane peeling,whil the other will receive the inverted internal limiting membrane flap technique.
To compare anatomic and functional results, and to evaluate postoperatively the healing process in 2 different techniques for the closure of the macular holes (MH)
Observational study of Internal Limiting Membrane peeled in macular Hole surgery and studied by Transmission electronic Microscopy (TEM) and Optical Coherence Tomography (OCT) findings in closed holes.
