Correlation between optical coherence tomography and multifocal electroretinogram findings with visual acuity after vitrectomy surgery for Retinal detachment.
Our study observes and analyses the influence of the duration of tamponade with silicone oil on the foveal and parafoveal thickness.
Tractional retinal detachment (TRD) that involves the macula and non-clearing vitreous hemorrhage are the main causes of permanent vision loss in patients with diabetic retinopathy and requires prompt surgical intervention. Macular peeling is a surgical technique used in many retinal diseases including diabetic retinal detachment. Our purpose is to determine whether retinal microcirculatory changes occur after anatomically successful diabetic vitrectomy, and whether changes in blood flow vary if ILM peeling was done and whether changes in macular perfusion affect the final visual outcome. The aim of this study is to non-invasively evaluate, with optical coherence tomography angiography (OCT-A), the anatomical changes of deep and superficial vascular density in the macula with and without macular peeling in diabetic vitrectomy.
The goal of this Phase 2 clinical trial is to learn about ONL1204 Ophthalmic Solution in terms of safety and how well the drug works in patients that have a macula-off (central point of vision) rhegmatogenous retinal detachment (RRD). The main questions it aims to answer are: - Does ONL1204 improve vision in macula-off RRD patients when used before retinal detachment repair surgery compared to patients that have surgery alone? - Is ONL1204 safe to use as an add-on drug before retinal repair surgery? Researchers will observe patients that receive two different dosages of ONL1204 Ophthalmic Solution (50 µg or 200 µg) compared to current standard therapy (no treatment) to see if there are differences in vision and safety outcomes.
Densiron is used as a tamponading agent for inferior retinal detachment with inferior retinal breaks However, data about the use of Densiron -68 for RRD with multiple retinal breaks; especially if involving both superior and inferior quadrants; are not sufficient.
This prospective randomised controlled trial will be conducted to investigate that increasing the vitrectomy cutting rate from 10,000 cut/min to 20,000 cut/min will result more efficiency and shorter core vitrectomy time, and it is equally safe as compared to the current 10,000 cut/min. We plan to target the patients undergoing for vitrectomy for common vitreoretinal pathology. Our plan is to conduct a randomised study with 2 arms, one with the higher cutting rate (20,000 cut/min) versus a second arm using the existing system 10,000 cuts/min.
Rhegmatogenous retinal detachment (RRD) is the separation of the neurosensory retina from the retinal pigment epithelium caused by the presence of a break that leads to the passage of fluid from the vitreous cavity into the potential subretinal space. It is a sight threatening disease, affecting largely people 50 years or older, with an annual incidence varying between 6.3 and 17.9 people per 100,000 population, and is unfortunately increasing. Although other surgical options do exist for the repair of primary RRD, pars plana vitrectomy (PPV) has clear advantages and is certainly effective in the treatment of these patients. Several agents are used for intraocular tamponade following PPV for RRD. These agents are either silicone oil (SO) or gases like air, perfluoropropane (C3F8), sulfur hexafluoride (SF6), or perfluoroethane (C2F6). In addition to the complications uniquely peculiar to using SO, research has found out that a reduction in retinal sensitivity on microperimetry was greater in SO tamponade in comparison with gas, as well as poorer visual outcome, microvasculature damage and affection of retinal layers including ganglion cell complex (GCC) in the SO group. Even though many studies were done to compare between SO and intraocular gas tamponades with respect to many aspects, only one study compared the effects SO had on macular vasculature and anatomy in comparison with air and no study at all to date has compared the SO to SF6 gas in terms of retinal vascular changes, correlating them to thinning of GCC and macular sensitivity, which is precisely the main aim of the current study.
Post-operative infectious endophthalmitis is devastating condition that causes a diffuse intraocular inflammation and may lead to blindness. Acute post-operative endophthalmitis usually presented within 6 weeks of intraocular procedure and diagnosis is confirmed by clinical examination and by the aid of B-scan ultrasonography.
To examine and to compare the evolution of aqueous flare from presentation until the third postoperative month in a series of consecutive patients who underwent primary vitrectomy for rhegmatogenous retinal detachment (RRD), in 4 groups of patients : - Group 1 : 48 eyes primarily treated with gas tamponade - Group 2 : 11 eyes primarily treated with silicone oil tamponade - Sub-Group G1RG : 8 eyes among Group 1 treated with gas after relapse - Sub-Group G1RS : 3 eyes among Group 1 treated with silicone oil after relapse
