NCT ID: NCT05897671 Completed - Clinical trials for Full Thickness Macular Hole

Foveal Sparing ILM Peeling With ILM Flap Transposition

Start date: June 1, 2023
Phase:
Study type: Observational

Foveal sparing internal limiting membrane (ILM) peeling with ILM flap transposition over the macular hole combines the benefits of foveal sparing ILM peeling with ILM flap techniques. Aim of this study is to retrospectively examine the rate of postsurgical macular hole closure, development of central atrophy in the foveal area, and improvement of best corrected distant visual acuity in a group of patients having undergone foveal sparing ILM peeling with ILM flap transposition for macular hole repair.

Full Thickness Macular Hole; Should it be Handled Subacutely?

Start date: April 30, 2023
Phase: N/A
Study type: Interventional

Full thickness macular hole, FTMH, is a retinal disease involving the fovea that cause central vision loss, metamorphopsia and central scotoma. The most effective treatment for FTMH is a pars plana vitrectomy and a tamponade with expansile gas. It is well known that vitrectomy accelerates cataract development. Vitrectomy can therefore be combined with cataract surgery in the same setting, a procedure that is shown to be safe, although increased inflammation and rates of central macular edema have been reported in some studies. Cataract surgery can also be performed prior or deferred until compromising the visual acuity after vitrectomy. Cataract-surgeries are more challenging in vitrectomized eyes due to lack of vitreous support and risk of loose zonules. The normal practice for FTMH at our department is therefore cataract surgery followed by vitrectomy 4 weeks later. A combined phaco-vitrectomy procedure is offered to patients who are at the labor market or when general anesthesia is required for the surgery. In non-presbyopic patients (<50 years) only vitrectomy is performed. The visual improvement after surgery seems to be dependent on preoperative characteristics, such as the preoperative visual acuity, size of the hole and the duration of symptoms. The duration of symptoms is a known prognostic factor, and recently shown that the longer duration, the worse visual outcome. The precise timeframe for the optimal final outcome is not known. The combined surgery is known to be safe in the treatment for epiretinal membrane, where a intravitreal gasfill is not necessary. However, the use of gas in FTHM surgery causes risk of increased movement of the newly inserted intraocular lens. This can lead to increased anterior segment inflammation with ensuing vision threatening cystic macular edema, as mentioned above. The purpose of this study is to investigate whether small FTMH with a short duration of symptoms have better visual outcome with a prompt combined phako-vitrectomy (within two weeks), compared to the current standard of care of receiving cataract surgery as soon as possible and vitrectomy 4 weeks later. How the delay of surgery affects the visual outcome will also be investigated, by including patients with longer duration of symptoms. The main hypothesis is that the chance of better visual outcome is higher for macular holes with early surgery compared to the current standard of care and that the duration of symptoms has significant impact on the visual outcome. Method The study consists of 2 parts. 1. Patients with idiopathic FTMH <400µm in diameter (as defined by The international vitreomacular traction study group classification), with a duration of symptoms of less than 30 days will be randomized into 2 groups: Group1: Combined phaco-vitrectomy within 2 weeks (after referral). Group 2: Current standard of care with cataract surgery as soon as possible and vitrectomy 4 weeks later. 2. Group 3: Patients with small holes <400µm, with a duration of symptoms of more than 3 months and less than one year will be included in this part of the study. These patients will be treated and followed as in Group 2. They will be reviewed a total of 7 times in Group 1 and 9 times in Group 2 and 3: a preoperative examination followed by 6/8 postoperative examinations. Additional examinations will be scheduled if needed.

Inverted Flap Versus Internal Limiting Membrane Peeling in Small Full Thickness Macular Holes

Start date: May 1, 2020
Phase: N/A
Study type: Interventional

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

NCT ID: NCT03332758 Completed - Retinal Detachment Clinical Trials

Inflammasomes in Cell Death in FTMH, ERM, and RRD

Start date: September 8, 2017
Phase:
Study type: Observational

Prospective study evaluating the role of inflammasomes in cell death in retinal detachment, full thickness macular hole, and epiretinal membrane. The investigators are collecting vitreous and subretinal fluid samples from patients with these conditions and evaluating activity of the inflammasome pathway with established assays.

NCT ID: NCT01226160 Completed - Clinical trials for Full Thickness Macular Hole

Pilot Randomised Controlled Trial of Posturing Following Surgery for Full-thickness Macular Hole

Start date: January 2005
Phase: Phase 0
Study type: Interventional

This is a pilot randomised controlled trial (RCT) to investigate the effect of postoperative face-down positioning on the outcome of macular hole surgery.

NCT ID: NCT01020760 Completed - Clinical trials for Full Thickness Macular Hole

Protocol for RCT of Posturing in Phacovitrectomy for Full Thickness Macular Hole (FTMH)

Start date: September 2008
Phase: N/A
Study type: Interventional

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.
