purpose: to compare the visual outcomes and complications of phacoemulsification surgery in patients with and without vitreous loss (vl). methods: a historical cohort study was performed on patients attending labbafinejad hospital who had underwent phacoemulsification surgery and was complicated by vl from april 2006 to march 2007. a control group was selected randomly from patients with uncomp...

BACKGROUND Rhegmatogenous retinal detachment (RRD) is the most common form of retinal detachment and an ophthalmic emergency. Here, we compared outcomes of primary RRD eyes operated with conventional scleral buckling (SB) with cryoretinopexy to those operated with standard pars plana vitrectomy (PPV). METHODS This is an institutional, retrospective, register-based, observational, comparative ...

BACKGROUND Rhegmatogenous Retinal detachment (RRD) is relatively unusual in general population: annual incidence is 1:10,000. Objective of this study was to compare the anatomical and functional outcome of primary retinal re-attachment surgery in phakic and pseudophakic eyes. METHODS A case series comparative study was carried out at Al-Ibrahim Eye Hospital, Karachi from July 2008 to June 200...

We use double-mode RR Lyrae (RRd) stars from the macho variable star database of the Large Magellanic Cloud (LMC) to estimate its distance, by utilizing photometric data, linear pulsation and stellar atmosphere models. If we set EB−V = 0.11 and [M/H]= −1.5 for LMC, we get M − m = 18.52 mag, which is in agreement with the value obtained from Galactic cluster RRd stars. Although the formal statis...

Although it is well established that cyclin-dependent kinases phosphorylate and inactivate Rb, the Raf-1 kinase physically interacts with Rb and initiates the phosphorylation cascade early in the cell cycle. We have identified an orally active small molecule, Rb/Raf-1 disruptor 251 (RRD-251), that potently and selectively disrupts the Rb/Raf-1 but not Rb/E2F, Rb/prohibitin, Rb/cyclin E, and Rb/...

BACKGROUND This meta-analysis was performed to determine the effectiveness of steroids as an adjunct following rhegmatogenous retinal detachment (RRD) surgery. METHODS RRD patients with or without proliferative vitreoretinopathy (PVR) were included. The treatment group included patients in whom steroids were used as an adjunct and a control group in which placebo was used. Only randomized con...

A new algorithm of Demmel et al. for computing the singular value decomposition (SVD) to high relative accuracy begins by computing a rank-revealing decomposition (RRD). Demmel et al. analyse the use of Gaussian elimination with complete pivoting (GECP) for computing the RRD. We investigate the use of QR factorization with complete pivoting (that is, column pivoting together with row sorting or...

OBJECTIVE To assess the outcome and risk factors for failure of pneumatic retinopexy (PR) in eyes with primary rhegmatogenous retinal detachment (RRD). METHODS Data of patients who underwent PR for the repair of primary RRD, from January 1, 2000, through June 30, 2011, were retrieved from medical records and retrospectively analyzed. Patients with a follow-up time of less than 4 months were c...

PURPOSE To describe the clinical features and surgical outcomes of rhegmatogenous retinal detachment (RRD) following myopic laser in situ keratomileusis (LASIK). METHODS In a retrospective, non-comparative case series, 46 eyes that had undergone vitreoretinal surgery for management of RRD following myopic LASIK were identified. Data was reviewed with emphasis on characteristics of the RRD, em...

BACKGROUND Pars plana vitrectomy (PPV) is preferred surgical procedure for the management of complex rhegmatogenous retinal detachment (RRD). The purpose of this study was to evaluate the anatomical results of primary PPV for the treatment of primary complex RRD and to determine the influence of lens status, tamponading agent, preoperative proliferative vitreoretinopathy (PVR) and axial length ...
