Active clinical trials for "Retinal Perforations"

The purpose of this investigation was to determine the incidence and the factors that cause a reopening of a macular hole (MH) after a surgical closure.

To describe the technique and outcomes of using either inverted or free internal limiting membrane flap in the management of retinal detachment due to paracentral retinal breaks.

Retrospective medical chart review of patients undergoing surgical repair of idiopathic macular hole

Funds autofluorescence (FAF) indicates hyper fluorescence at the macular hole in the patients with macular hole. Investigators investigate the association between FAF and visual acuity, recovery of foveal microstructure, and FAF in surgically closed macular holes.

The macular hole formation takes place in the centre of the retina. A closure of the macular hole is believed to take place if the central retinal area is kept dry in the postoperative period. Therefore the eye is filled with a gas mix and the patients are urged to avoid the supine position in the first postoperative days. The investigators use the "tennis ball technique" where a tennis ball is fastened in the back of the night shirt in order to help patients compliance in avoiding the supine sleeping position. The investigators have developed a positioning measuring device which can measure the extent of supine positioning time. Patients are to sleep two nights with the positioning measuring device, one night with a tennis ball in the back of the night shirt and one night without. Hereby the investigators search new knowledge concerning patients compliance and verification of the "tennis ball technique".

To evaluate the correlations between anatomical and functional changes studied with microperimetry (MPM) and spectral-domain OCT (SD-OCT) in patients after successful repair of idiopathic macular hole (MH).

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.

Surgical outcome of patients with macular drusen and co-existing abnormalities of the vitreoretinal interface, who routinely undergo pars plana vitrectomy with membrane peeling, is evaluated. Best corrected visual acuity as well as optical coherence tomography data are compared at baseline and last follow up. The rate of development of choroidal neovascularization postoperatively is noted.

A retrospective review of medical charts of patients having undergone vitrectomy with ILM Peeling and ILM flap technique for macular hole repair.

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.
