BACKGROUND To present the effect of erythropoietin for the treatment of methanol optic neuropathy. METHODS Two patients with methanol optic neuropathy were treated with 10,000 IU of intravenous erythropoietin twice a day for 3 days, 500 mg of methylprednisolone twice a day for 5 days (followed by 2 weeks of oral prednisolone [1 mg/kg per day]), and daily(More)
This article proposes a new architecture for distributed data management and update massage exchange in massively multiuser virtual environments. The key points in the design of such environments are scalability and QoS-aware message delivery. Therefore it requires robust distributed algorithms in a dynamic peer-to-peer system with frequent node arrivals(More)
An enhanced media access control (MAC) layer protocol that uses the signaling method benefits of the physical layer in order to provide different levels of quality to different users in optical code-division multiple-access (OCDMA) packet networks is presented. In the proposed network architecture the users are categorized into two classes of service, one(More)
Massively multi user virtual environment (MMVE) applications must face the challenge of dealing with update message exchange among a large set of nodes distributed over the Internet. Therefore design of scalable network protocols is a major concern in such large scale distributed architectures. Several approaches have been proposed to aid update exchange in(More)
In this paper, we present a novel algorithm for partner selection and power allocation in the Amplify-and-Forward cooperative diversity that minimizes the required total transmit power by given outage probability constraint. We represent the problem with new formulation and solve the optimal power allocation by KKT method for a fixed set of partners. For(More)
Neovascular glaucoma is a secondary glaucoma with grave prognosis which follows ischemic retinal disorders in the majority of cases. Mediators that induce new vessel formation such as the vascular endothelial growth factor-A seem to play a key role in the pathophysiology of this condition. Herein, we report 2 cases with neovascular glaucoma secondary to(More)
PURPOSE To determine the effect of intravitreal bevacizumab (IVB) on neovascular glaucoma (NVG) in terms of iris neovascularization (NVI), intraocular pressure (IOP), and visual acuity. METHODS This randomized controlled trial included 26 eyes of 26 patients with NVG. All eyes received conventional treatment for NVG and were randomly allocated to three(More)
PURPOSE To evaluate intrasubject asymmetry in central corneal thickness (CCT) among patients with primary open-angle glaucoma (POAG) as compared with that of normal subjects and to determine whether the eye with thinner cornea has more severe glaucomatous visual field damage. METHODS In this case-control study, CCT of both eyes was measured using an(More)
PURPOSE To determine corneal biomechanical changes following major glaucoma procedures. METHODS In a prospective comparative case series, corneal biomechanical properties were assessed using the Ocular Response Analyzer (ORA, Reichert Inc., Depew, New York, USA) before and 3 months after surgery in 89 eyes of 89 patients undergoing trabeculectomy +(More)
OBJECTIVE To investigate penetrance and expressivity of CYP1B1 genotypes associated with primary congenital glaucoma (PCG). DESIGN Observational case series, systematic review, and comparative analysis of the literature. PARTICIPANTS Forty probands affected with PCG, 16 siblings affected with PCG, and 103 siblings and 75 parents of the probands reported(More)
