یکی از مهمترین کاربردهای پردازش تصویر در زمینه تصاویر پزشکی است. تصاویر در تشخیص و افتراق بیماری های چشمی، که بطور بالینی قابل تشخیص نیستند، نقش بسزایی دارند. جداشدگی زجاجیه خلفی (posterior vitreous detachment(pvd)) که در اثر دژنراسیون زجاجیه و به دنبال آن جدا شدن اتصال آن از شبکیه، بوجود می آید، به خودی خود اکثرا بی خطر بوده و فقط باعث ایجاد مگس پران (وجود یک سایه متحرک در میدان بینایی) و جرقه...
The differential diagnosis of serous retinal detachment (RD) includes Vogt-Koyanagi-Harada syndrome, severe hypertensive choroidopathy, posterior scleritis, multifocal choroiditis, metastatic tumor, and uveal effusion. Some cases of serous retinal detachment occur as a result of central serous chorioretinopathy (CSCR). Typical CSCR generally affects healthy middle-aged males and is characterize...
purpose: to evaluate the efficacy of sub-tenon block (preemptive analgesia) following general anesthesia and before the beginning of scleral buckling and cryopexy in retinal detachment (rd) surgery on decreasing intra- and post-operative complications. methods: sixty eight patients scheduled for rd surgical repair with asa (american society of anesthesiologists) class і or ii were enrolled in t...
Prevention of rhegmatogenous retinal detachment (RD) in susceptable eyes is necessary. In order to evaluate the role of signs and symptoms of the treated eyes in preventing RD, this study performed in prophylactically laser treated (PLT) eyes in Rasul-e Akram Hospital from 1991 to 1999. This is an exisiting data study from the records of the patients who underwent PLT around the retinal lesio...
purpose: to evaluate the outcomes of internal tamponade using heavy silicone oil in complicated retinal detachment (rd) surgery. methods: in this interventional case series, patients with complicated rd involving the inferior retina were enrolled. inclusion criteria included rd secondary to proliferative vitreoretinopathy (pvr cp6 and/or ca6) involving the inferior retina, inferior or posterior...
purpose: to evaluate the effect of oral prednisolone on visual outcome and complications of scleral buckling (sb) in patients with rhegmatogenous retinal detachment (rrd). methods: in a randomized double-blind placebo-controlled trial, patients with acute rrd who underwent sb were randomly divided into two groups. oral prednisolone was administered for the treatment group and placebo for the co...

Background: The pathophysiology of rhegmatogenous retinal detachment (RRD) has remained a challenging subject in ophthalmology. The aim of this study was evaluating the leading causes and treatment options of RRD. Methods: The study was performed by a review of 10 years (2004-2014) related literature emerged in PubMed on the pathophysiology and treatment of rhegmatogenous retinal det...
purpose: to determine factors that affect and predict final visual acuity, retinal attachment, and ocular survival after open-globe injuries. methods: one-hundred sixteen eyes with open globe injuries were evaluated longitudinally from september 2001to february 2004. age, sex, involved eye, best corrected visual acuity (bcva), afferent pupillary defect (apd), size and location of laceration, ca...
PURPOSE The incidence of retinal detachment in Blacks is generally considered to be low though there are few supporting studies in Africa. This study, thus, aimed at describing the clinical profile of patients with retinal detachment in Southwest Ethiopia. METHODS A hospital-based study was done on all consecutive retinal detachment patients who presented to Jimma University Hospital over six...
