Filter by:Individuals operated for rhegmatogenous retinal detachment will be prospectively evaluated for postoperative retinal shift. Fundus autofluorescence will be used to evaluate retinal shift that will be correlated to visual acuity, metamorphopsia, aniseikonia, and stereopsis.
From July 2015 to December 2015, clinical record of 8 consecutive cases of macular hole with retinal detachment in high myopia treated with combined inverted and free ILM flap insertion into the hole were retrospectively reviewed. The anatomical and function outcomes were assessed.
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.
The study is collecting data along with other academic institutions regarding the accuracy of ocular ultrasound in diagnosing retinal detachment.
The study aimed to investigate the effectivity of bupivacaine 0,5% as post-operative analgesia in intravitreal silicone evacutaion surgery
Silicone oil has been used as a surgical tool in complicated retinal detachment surgery. There are some complications occurring in pars plana vitrectomy with silicone oil tamponade. Silicone oil emulsification is one of the complication that may result in severe sequels that are difficult to treat. It is believed that low viscosity silicone oil has more risk to develop emulsification than high viscosity silicone oil. Up to now, however, there is no conclusive guideline that which types of silicone oil is suitable for these complicated retinal detachment surgeries and what is the appropriate time to remove the oil. This prospective study aims to study the silicone oil emulsification comparing between low viscosity and high viscosity silicone oil after complicated retinal detachment surgery.
To evaluate efficacy of vitrectomy with inverted internal limiting membrane (ILM) flap technique for macular hole retinal detachment (MHRD) in highly myopic eyes, and to demonstrate postoperative clinical course of MHRD after inverted ILM flap technique using swept-source optical coherence tomography (OCT)
Objective: To compare outcomes of retinal detachment repair following pneumatic retinopexy (PnR) versus pars plana vitrectomy in terms of anatomical success, functional success and patient quality of life in patients with extended criteria. Methods: A prospective, randomized, controlled trial will be conducted with 178 patients presenting at St. Michael's Hospital with primary retinal detachment (RD). Inclusion criteria include: a single or multiple retinal tears in detached retina between 7 and 5 o'clock being of any size and any distance apart from each other, including giant retinal tears with inferior aspect above 5 and 7 o'clock, RD with no identifiable tear but where suspected tear is between 7 and 5 o'clock, retinoschisis with RD if tears are located between 7 and 5 o'clock, mild proliferative vitreoretinopathy, none or mild vitreous hemorrhage. Patients will be excluded if there is a small retinal tear or multiple tears less than 30o apart between 8 and 4 o'clock in detached retina, retinal tear in detached retina between 5 and 7 o'clock, <18 years old, inability to read English, mental incapacity, previous history of RD, scleral buckle or vitrectomy in index eye, inability to maintain appropriate head posture at post-operative period and inability to visualize peripheral retinal due to media opacity. Patients will be randomly allocated into two groups: PnR + cryotherapy/laser or vitrectomy + cryotherapy/laser and the intervention will take place within 24 hours and 72 hours for attached and detached macula status, respectively. Patients will undergo a complete ophthalmological examination, including visual acuity and fundus assessment at baseline and at 3, 6 and 12 months after surgery. Visual acuity will also be measured at 1, 7 and 30 days after surgery. Global health related quality of life will be evaluated with the SF-36v2 questionnaire at baseline, 1 month, 1 and 2 years after intervention, while the VFG25 questionnaire will be applied at 3, 6, 12 and 24 months after surgery to measure vision related quality of life.
26 patients presenting a rhegmatogenous retinal detachment with more than 4 days of duration will be prospectively included. A single dose of ursodeoxycholic acid will be administered orally before surgery at different time-points in 22 subjects. Standard surgery will be performed and ocular samples will be collected during the procedure. Ursodeoxycholic acid treatment will be continued in treated patients during 3 months after surgery. Ocular and serum samples from the 4 untreated patients will serve as negative controls for the determination of UDCA levels.
This study investigates the effectiveness of a simple treatment to prevent proliferative vitreoretinopathy (PVR). Intraoperative intravitreal 5-fluorouracil (5-FU) and low molecular weight heparin (LMWH) is used as a prophylactic therapy in high-risk patients with primary rhegmatogenous retinal detachment (RRD). Our major motivation is to reduce the incidence of PVR in the group that receives the trial drug.
