Abstract Retinal dystrophies associated to mutations in the CRB1 gene comprise a wide array of clinical presentations. A blood sample from patient with family history CRB1-retinal dystrophy was used prepare iPSC line ESi082-A. The genotype donor, affected perifoveal-bilateral macular includes one frameshift deletion and hypomorphic allele. ESi082-A cell has been characterized for pluripotency w...

purpose : to determine the optical coherence tomography (oct) findings in eyes with idiopathic perifoveal retinal telangiectasis (ipt) methods : this study is a retrospective review of patient charts, oct, fundus photography, related to 16 eyes (11 patients). results : the most consistent finding of idiopathic perifoveal telangiectasia seen in 93.7% of eyes (15 eyes) on oct was the presence of ...

bacteriorhodopsin operates as a light/proton transfer pump which converts the light energy into a proton gradient. energy stored in the proton gradient can be used in a variety of ways. bacteriorhodopsin producing sources are some halobacterium species such as halobacterium sodomense and halobacterium salinarum which continue to grow in harsh and salt-saturated conditions. two types of red pigm...

retinal vein occlusion (rvo) is a common retinal vascular occlusive disorder and is associated with a variety of systemic risk factors. the aim of this study was to investigate whether the underlying diseases were evaluated and managed appropriately by ophthalmologists. we performed a study of 1344 patients with retinal vein occlusion (rvo). patients were evaluated with a questionnaire includin...

background and objectives:purtscher's retinopathy occurs with sudden loss of vision. in this article, a case of post-partumpurtscher's-like retinopathy was investigated. case report:the patient was an 18-year-old woman who presented with severe bilateral loss of vision, three days after childbirth. no systemic abnormalities were observed except preeclampsia. the results of ophthalmosc...

purpose: to study the pattern of perfusion of central retinal artery (cra) after 0.1 ml intravitreal injection of bevacizumab to verify the need for any maneuver to decrease the intraocular pressure (iop) including anterior chamber paracentesis (acp) methods: this is a prospective, interventional, noncomparative case series. patients receiving intravitreal injection of bevacizumab for choroidal...

purpose: true neoplasm (adenocarcinoma) of retinal pigment epithelium (rpe) is very rare since it can be misdiagnosed as intraocular malignant melanoma it is of importance to know the clinical and pathologic aspects of this neoplasm. here, we report a case of adenocarcinoma of rpe. methods: case report. results: a 60-year-old man with progressive loss of the vision of the right eye was enucleat...

results this review explores the relationship between metabolic syndrome, including all its components, and various ocular conditions such as retinopathy, central retinal artery occlusion, cataract and elevated intraocular pressure. context metabolic syndrome (metabolic syndrome x) is a prevalent cluster of risk factors that include high bmi, hypertension, insulin resistance and dyslipidemia. i...

data suggest that the multifocal electroretinography (mferg) may have a role in the assessment of patients with central retinal vein occlusion (crvo). to explore the mferg responses in patients with crvo. mferg responses were recorded at 61 discrete retinal locations from both eyes of 25 patients diagnosed with retinal vein occlusions within 3 weeks of onset. the latencies and amplitudes of ave...

exudative retinal detachment (erd) may be seen with many ocular pathologies including malignancies. among malignant causes, metastases of breast and lung carcinoma are most common. a 50-year-old woman referred to our clinic with history of decreased visual acuity in her right eye since 3 months before referral. the visual acuity was counting fingers at 2 meters and 6/10 in the right and left ey...
