PURPOSE To report a new method for optical sectioning of the chorioretinal vasculature to improve the visualization of vascular abnormalities due to chorioretinal eye diseases. METHODS An imaging system was developed for optical sectioning of the vasculature called chorioretinal optical sectioning (CROS). CROS consists of projecting a laser beam at an angle on the retina after injection of a ...

We report a case of recurrent choroidal neovascularization (CNV) in an eye with chorioretinal coloboma. A 36-year-old woman presented complaining of decreased visual acuity (VA) in her left eye. Best corrected visual acuity (BCVA) was 20/200 and iris coloboma was observed. Funduscopy and fluorescein angiography (FA) showed CNV in the superior extrafoveal region with chorioretinal coloboma reach...

PURPOSE To establish baseline and variability of oxygen tension (PO(2)) measurements in the choroid, retinal arteries, capillaries, and veins of spontaneously breathing anesthetized rats and determine the effect of a moderate surgical procedure on the chorioretinal PO(2). METHODS Our previously established optical section phosphorescence imaging technique was utilized to measure PO(2) in the ...

Purpose: Transscleral diode retinal photocoagulation (diopexy) is becoming an accepted technique in the treatment of selected retinal diseases. The objective of this study is to evaluate diopexy technique in the production of adhesive chorioretinal lesions during the surgical treatment of the rhegmatogenous retinal detachment. Methods: 25 patients with rhegmatogenous retinal detachment were enr...

Purpose Here, we have tried to quantify the chorioretinal blood perfusion in patients who are clinically identified to be suffering from retinal ischemia using arterial spin labelling (ASL) MRI. Method Four participants, diagnosed with retinal ischemia based on their structural OCT and angiography test, were then scanned using anatomical MRI as well as ASL. We optimized MR parameters to maxim...

purpose : to investigate long-term ocular manifestations of ocular behcet’s disease (bd), and the causes for blindness methods : in august 2008, at shariati hospital of tehran (behcet unit) all files of the ocular bd patients from 1976 to 2008 who were legally blind (visual acuity=20/200 or less) at least in one eye at the last visit and had at least three years of follow-up were reviewed and t...

Pregnancy is a long-term, temporary, physiological state that occurs in women's lives. the period which many anatomical and changes occur to meet needs of developing fetus. During this period, various are seen eye. Some changes, especially immunological system, may cause some inflammatory chorioretinopathy posterior segment. This can different levels vision loss. The main diseases during pregna...
