BACKGROUND Age-related changes in nociception have been extensively studied in the past decades. However, it remains unclear whether in addition to the increased incidence of chronic illness, age-related changes in nociception contribute to increased prevalence of pain in the elderly. Although a great deal of evidence suggests that nociception thresholds increase with aging, other studies yield...
BACKGROUND: Many behavioral and physiological variables exhibit daily rhythmicity. Few investigations of the daily rhythmicity in nociception have been conducted, and conflicting results have been obtained. The present study evaluated the daily rhythmicity in nociception in Wistar rats. METHODS: Nociception was investigated by Eddy's hot plate method, tail immersion method, and tail clip method...
purpose: to evaluate the correlation between corneal power and corneal horizontal white to white diameter in myopic patients scheduled for lasik surgery. methods: overall, in 840 eyes of 420 myopic subjects scheduled for lasik, horizontal white to white diameter and mean corneal power were obtained using orbscan ii. pearson correlation test and regression analysis were used to detect any correl...
purpose : to evaluate the effects of topical sesame oil in the treatment of severe corneal alkali injury in rabbits methods : in a double-blind experiment, 30 healthy white rabbits were randomized into a sesame oil treatment group (n=15) and a control group (n=15). under general anesthesia, severe corneal alkali injuries were induced by application of 1 n sodium hydroxide for 40 seconds to the ...
purpose: to present two patients with acute corneal hydrops, superimposed with infectious keratitis using topical steroids. patients and findings: the first case was a 44-year-old man with acute corneal hydrops in his left eye which was on topical steroids for one week. visual acuity was hand motion at presentation and there was a large epithelial defect with stromal infiltration and corneal ed...
Purpose: To report the clinical presentation, histopathologic findings, and surgical treatment in a series of cases with primary corneal keloid. Case Reports: Six Iranian patients (a father and two sons, a mother and her daughter, and one isolated male patient) without any history of corneal trauma or systemic diseases were clinically and histologically evaluated for a slowly-growing, white opa...
ABSTRACT This study is done to examin the role of smears, cultures, and sntibiotic sensitivity testing in the treatment of infectious keratitis. A prospective study was performed for 100 patients in Rasool Akram hospital ophthalmology department. After routine examination by slit lamp, evaluation of corneal epithlium, stromal edema and infiltration, AC reaction or hypopyon, all underwe...
Background: To investigate the relationship between high-order aberration (HOA) changes and RCST/CT (residual corneal stroma thickness/corneal thickness) after femtosecond LASIK surgery.
Purpose: To report a 3-decade eye bank data and activity of the Central Eye Bank of Iran (CEBI). Methods: All the eye bank records in terms of procured eyes, utilized tissues, corneal transplants per capita, and indications for keratoplasty over the last 3 decades were analyzed. Results: During the last 27 years, 115 743 whole eyes were donated, among which 114 169 eyes were donated between 199...
Broad nervous circuits originate from the hypothalamic arcuate nucleus project to many parts of the brain which are related to pain perception. Insulin receptors have been found in the arcuate nucleus. Since nociception may be affected in type 1 diabetes, the present study aimed to investigate the intra-arcuate nucleus insulin role in pain perception in STZ-induced diabetic and healthy rats. Fo...
