purpose : to report a patient with branch retinal vein occlusion (brvo) and serologic evidence of primary cytomegalovirus (cmv) infection case report : we have reported a 27-year-old male with a complaint of sudden decrease in right eye vision starting a few days before. results : immunoglobulin g (igg) seroconversion indicated primary cmv infection. conclusion : involvement and obstruction of ...

purpose: to report an idiopathic retinal vasculitis, aneurysm, neuroretinitis (irvan) case treated with one session of panretinal photocoagulation (prp) and intravitreal bevacizumab (avastin) case report: a 13-year-old boy was diagnosed as an irvan syndrome. systemic examination, fundus angiography, brain mri were performed to evaluate the patient. treatment with one session of prp, retinopexy ...

This paper presents an automated method for detecting microaneurysms in the retinal angiographic images by using image processing techniques. In the presented method, in order to fade or remove the pseudo images, first retinal images are pre-processed. Then microaneurysms are identified by circular Hough transform. In the existing methods of dete...

Background: Chronic myeloid leukemia (CML) is a myeloproliferative hematopoietic malignancy with a heterogeneous proliferation of hematopoietic cells in the bone marrow. The ocular manifestations are rare symptoms of CML. In this case report, a CML patient with retinal hemorrhage is reported as an uncommon symptom. Case presentation: A 35-year-old man was referred due to decreased right eye vi...

this article reviews clinically relevant data regarding traumatic maculopathy (tm), frequently observed in clinical practice, especially due to sport or traffic accident injuries. it is characterized by transient gray-whitish retinal coloration and reduction of visual acuity (va) with closed, blunt object globe trauma of their prior. it may be limited to the posterior pole (berlin’s edema), o...

purpose : churg-strauss syndrome (css) is a rare form of small vessel necrotizing vasculitis. retinal artery and vein occlusion are very rare findings in these patients and they are treated by high-dose corticosteroids and cytotoxics. we describe a rare case of css under high-dose corticosteroids and cytotoxic treatment, presenting central retinal artery occlusion (crao). case report : a 45-yea...

in the present study, theoretical chemical reactivates photo isomerization in cis-retinal as a natural photo switch in vision. dft hybrid functional, b3lyp and, post-hf method, were the theoretical methods applied utilizing g09 software. 6-31g+ (d,p) basis set employed for structural optimizations, and single point computations performed using b3lyp/6-31g+(d,p). the isomers cis molecule retinal...

purpose: to determine agreement between peripapillary retinal nerve fiber layer (rnfl) thickness measurements by two different spectral domain optical coherence tomography (sd-oct) machines. methods: both eyes of 89 subjects were evaluated using cirrus oct (carl zeiss meditec, inc. dublin, ca, usa) and topcon oct (3d oct 1000, topcon corporation, tokyo, japan). one eye was randomly selected in ...

purpose: to evaluate the etiologic and epidemiologic findings in central retinal artery occlusion (crao) patients in a tertiary eye center in tehran, iran. methods: all patients with crao refered to the emergency department of farabi hospital during 2001-2002 were enrolled in the study. all patients received routine treatment and were followed for 3 months. cardiology consult was done for all p...
