Active clinical trials for "Retinal Detachment"

The aim of the study is to evaluate the influence of silicone oil on thickness of the retinal nerve fiber layer by using optical coherence tomography (OCT) in patients following pars plana vitrectomy.

Retinoschisis is usually a rare self-limited disease and seldom shows progression. There a splitting of the neurosensory retina occurs usually in the inferior temporal. Patients usually have good visual acuity and are asymptomatic. Combination of an inner and outer layer hole is considered high risk factor for development of a schisis detachment. The most important differential diagnosis is an retinal detachment, since if misdiagnosed unnecessary treatment is provided. In clinical examination, both can appear very thin and transparent. Therefore exact diagnosis of retinoschisis and retinal detachment has to be assessed and regular follow-up controls have to be conducted for sufficient recognition of progression.

To examine morphological and functional results after pars plana vitrectomy (PPV) with SF6 gas tamponade due to macula-on and macula-off rhegmatogenous retinal detachment (RRD) during six months of the follow-up.

Patients may experience metamorphopsia, or image distortion, after having vitrectomy to repair their rhegmatogenous retinal detachments (RRDs) especially those with a detached macula. Retinal displacement, as measured on autofluorescence photography, likely contributes to this distortion. There is no study in the scientific literature comparing the rate of retinal displacement and its association with visual function, including metamorphopsia, in patients undergoing different procedures for RRD repair. Based on the recently published PIVOT trial, patients who underwent Pneumatic Retinopexy (PnR) had less vertical distortion at 12 months than patients who had Pars Plana Vitrectomy (PPV). It is hypothesized that PnR will cause less retinal displacement than PPV for patients with macula-off primary retinal detachment.

The purpose of this study is to investigate the loss of retinal cells following retinal detachment surgery using an imaging device called an adaptive optics camera. The retina is a thin layer which lines the back of the eye. It is sensitive to light (like the film in a camera) and is necessary for vision. If a hole or rip develops in a retina it can become detached. The macula is the central portion of the retina which the investigators use for fine vision. This area can also become detached as part of a retinal detachment. Proliferative vitreoretinopathy (PVR) is an abnormal scarring response inside the eye which can occur when the retina detaches. It can adversely affect the outcome of the retinal detachment repair and is associated with a worse visual prognosis. The investigators want to investigate retinal cell loss in patients with retinal detachments that have developed PVR when the macula has been involved. The investigators plan to compare them to two other groups of patients, who have not developed PVR: Patients with macula-involving retinal detachments without PVR Patients with macula-sparing detachments without PVR The investigators will investigate retinal cell loss in these types of retinal detachments using adaptive optics imaging. This is a non-invasive imaging technique which allows the investigators to view the retina at very high magnification. Investigating photoreceptor loss and its association with visual outcome in this way should help to guide future interventions in promoting retinal regeneration. The investigators plan to recruit 25 patients at one UK hospital. The project is funded by the charity Fight for Sight.

The purpose of this study is to assess the association of retinal detachment (separation of the retina [the innermost layer of the eyeball] from its connection at the back of the eye) with exposure to oral ciprofloxacin or oral fluoroquinolones.

The purpose of this study is to evaluate the corneal changes after performing 20 gauge vitrectomy associated with scleral buckling for the treatment of rhegmatogenous retinal detachment.

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.

The purpose of this study is to evaluate whether there is an increased risk of achilles tendon rupture (ATR), retinal detachment (RD) or aortic aneurysm and dissection (AAD) following exposure to fluoroquinolone (FQ) or other antibiotics (amoxicillin, azithromycin, trimethoprim and trimethroprim/sulfamethoxazole) or febrile illness not treated with antibiotics, using a study design that minimizes the impact of confounders not usually captured in health services databases such as heredity or smoking.

Our study observes and analyses the influence of the duration of tamponade with silicone oil on the foveal and parafoveal thickness.
