To determine whether corneal input is processed similarly at rostral and caudal levels of the spinal trigeminal nucleus, the response properties of second-order neurons at the transition between trigeminal subnucleus interpolaris and subnucleus caudalis (Vi/Vc) and at the transition between subnucleus caudalis and the cervical spinal cord (Vc/C1) were compared. Extracellular single units were r...
OBJECTIVES Evaluation of pain during and after phacoemulsification with topical anesthesia in patients with senile cataract and investigation of factors related with pain. MATERIALS AND METHODS Ninety-two adult patients scheduled for routine clear corneal phacoemulsification with topical anesthesia who had no previous cataract surgery in their fellow eyes were included in the study. Verbal pa...
Purpose: To determine the etiologic factors on rejection and failure rates and ocular surface changes after corneal transplantation by either DALK or PKP, in cases of keratoconus (KCN). Methods: In this cross-sectional study, considering the existing data, patients with keratoconus referring to Labbafinejad Medical Center from 2006 to 2016, who underwent corneal transplantation, were enrolled a...

Methods this is a true experimental study with test only design 18 New Zealand white rabbits. Sample were divided randomly two groups, each 9 The right eye of rabbit exposed alkali injury 1N NaOH under general anesthesia. First group was given eyedrops for the second group. ...
Background: Keratomycosis is a fungal infection of the cornea which could be sight-threatening and even causes eye loss. Considering the high humidity and the dominance of agriculture as important predisposing factors of keratomycosis in north of Iran, this study was carried out for diagnosis of fungal keratitis in patients with corneal lesions in Rasht, Gilan province, Iran. Methods: This de...
Background: In this study were focused on corneal cells changes in keratoconus disease, as there are differences between results of other studies that were done on keratokonic eyes. And the chief purpose was a comparison between keratoconus and normal population based corneal endothelium (in cell density, pleomorphism and polymegethism of cells). Methods: This study is an observational study a...
This study was performed to evaluate the efficacy of anterior keratoplasty with microkeratome in the improvement of visual acuity (V.A) in superficial corneal disorders in patients admitted to Labbfi Nezhad hospital and Tehran Bassir Clinic . &nbs...
Background: Keratoconus is a common complication among corneal defects. As a result of expeditious and extensive progress of medical science in recent decades, corneal ring implantation has turned into a successful surgical procedure to correct the vision of Keratoconus patients; however, selecting the right patient is essential in the success of the operation. The prediction of corneal conditi...
UNLABELLED Wilsons disease, characterized by cirrhosis, extrapyramidal symptoms and Kayser-Fleischer corneal rings, is a rare hereditary disease of human copper metabolism. Clinical findings in Wilsons disease are complex and neurological symptoms such as tremor, dysarthria, rigid dystonia, seizures, psychiatric disorders, acute liver failure, chronic hepatitis or cirrhosis may develop.

This paper reports in detail, for the first time, on two anesthetic procedures performed on a 15-yr-old, 530 kg, adult male Sumatran rhinoceros (Dicerorhinus sumatrensis). The anesthetic procedures were carried out in order to perform semen collection via electro-ejaculation, using well-established methods, and in order to examine and sample bilateral corneal opacities. Anesthesia for the first...
