Active clinical trials for "Retinal Detachment"

This study provides further theoretical guidance for clinical application of FCVB through observing and collecting various indicators before and after surgical treatment of the FCVB in the real world.

The purpose of the article is, to investigate the efficacy and safety of perfluorocarbon liquid (PFCL) ,as a short term postoperative tamponade for treating retinal detachment ,associated with giant retinal tears.

Phacoemulsification with implantation of posterior chamber lenses represents the gold standard of care for patients needing lens surgery, but there is an increased risk of developing pseudophakic retinal detachment after surgery. Especially myopic patients have an even higher risk of pseudophakic retinal detachment compared to the general population. The aim of this multicenter study is to document the presence and/or post-operative development of posterior vitreous detachment (PVD) and to assess its influence on the incidence of retinal detachment (RD) in myopes in a time period of three and five years after lens surgery. 618 eyes of patients scheduled for regular lens surgery will be included, defined by an axial length of 25.0 mm or more. To examine the vitreous status, all patients will receive a comprehensive eye examination pre-operatively, including funduscopy with assessment of a Weiss ring and optical coherence tomography (OCT). Patients will be divided into two groups, group A with pre-operative complete PVD and group B with no/partial PVD. Group A will be invited for one follow-up visit (two months post-operatively) followed up by telephone interviews at one, two, three and five years after surgery to determine occurrence of pseudophakic retinal detachment. Group B will be invited for follow -up examinations at two months, six months and one year after surgery to document occurrence of PVD (if a PVD is present at one of the follow-ups, no more visits are necessary). Two, three and five years after surgery, all patients from group B will be interviewed by telephone, as in group A, to document the occurrence of pseudophakic retinal detachment. In the recent literature the association between the occurrence of PVD pre-/post-operative and RD after lens surgery is well documented but not described for myopic patients. The results of this multicenter study should help to tackle the problem of RD prediction in myopic patients depending on their pre-operative vitreous status, especially in the setting of refractive lens exchange.

Patients are required to position prior to retinal detachment surgery. We seek to see whether there is a correlation between the performed positioning and retinal detachment progression/regression in fovea-on retinal detachment patients.

silicone oil tamponade removal after previous injection of complicated retinal detachment can be achieved with active suction followed by triple air-fluid exchange or prolonged lavage of the vitreous chamber to remove emulsification. Purpose of the study is to compare the amount of silicone oil emulsification droplets within the lavage fluid in case of air exchange and simple lavage to compare which technique removed the highest percentage of emulsion. This is achieved by comparing consecutive samples of lavage fluid

All existing medical literatue regarding axial length (AL) changes after scleral buckling surgery for retinal detachment, descibes changes after solid silicone buckling. In this hospital, the investigators use only silicone sponge buckling, which has different properties and a different buckle profile. there are no studies in the literature describing tha AL changes after sponge buckling, or whether the AL change is less or more than with solid silicone buckles. The investigators wish to determine whether the AL change profile with their silicone sponge is significantly different, and if so, whether this is clinically important in determining the better choice of buckle material to be preferred.
