Fluorescein fundus angiography in 10 patients with a cerebral tumour of considerable size but without ophthalmoscopic papilloedema does not support the hypothesis that such patients have in fact minimal papilloedema. Absence of papilloedema in these cases usually indicates absence of persistently high CSF pressure.

purpose: to report a typical case of hla-a29 positive birdshot choroidipathy as the first report in iran. case report: a 43-year-old male subject without any systemic disease presented complainting of decreased visual acuity in both eyes for 5 years. visual acuity was 20/30 in his right eye and cf at 2 meters in the left eye. intraocular pressure was within normal limits bilaterally. corneas an...

Purpose. This study was performed to evaluate the relationship between intraocular pressure (IOP) and glaucomatous optic nerve change and thyroid factors in Korean population. Materials and Methods. The study included subjects who underwent health screening in Kangbuk Samsung Hospital. Detailed history taking and systemic and ocular examination including fundus photography were performed for al...

To accommodate the intake of food or liquid, gastric reservoir functions are important as the physiological refiex. There exist two rnajor responses as a reservoir function of the stomach ; adaptive and receptive relaxations. Adaptive reTaxation is a reflex in which the fundus of the stomach dilates in response to small increases in {ntragastric pressure when food enters the stornach. Receptive...

To accommodate the intake of food or liquid, gastric reservoir functions are important as the physiological reflex. There exist two major responses as a reservoir function of the stomach; adaptive and receptive relaxations. Adaptive relaxation is a reflex in which the fundus of the stomach dilates in response to small increases in intragastric pressure when food enters the stomach. Receptive re...

The authors present five cases of bilateral corneal disorders, on which they performed penetrating keratoplasty. All five patients were clinically blind and after the surgery on one eye, they gained their visual independence. Visual acuity, intraocular pressure, fundus examination, and ultrasonography were used to evaluate the patients before and after the surgery.

An 18 year old Obese female with a history of hypothyroidism & PCOS presented complains headache for 5 days associated nausea and double vision 2 days. Her neurological examination together Cranial Nerves was Normal except bilateral restriction abduction, suggestive abucens nerve involvement. Fundus findings revealed grade III disc edema. Lumbar puncture indicated increased opening pressure MRI...

H2S is produced mainly by two enzymes:cystathionine-β-synthase (CBS) and cystathionine-γ-lyase (CSE), using L-cysteine (L-Cys) as the substrate. In this study, we investigated the role of H2S in gastric accommodation using CBS(+/-) mice, immunohistochemistry, immunoblot, methylene blue assay, intragastric pressure (IGP) recording and electrical field stimulation (EFS). Mouse gastric fundus expr...
