OBJECTIVE To study the effects of lacrimal gland removal on basal and reflex tear production and on the ocular surface in the squirrel monkey. METHODS Unilateral main lacrimal gland removal in 6 squirrel monkeys was followed by Schirmer testing, slit-lamp examination with fluorescein, and collection of basal and reflex (stimulated) tears for analysis of tear protein spectra between 0 and 20 k...
Background and Objective: Keratoconus is a disorder in cornea characterized by constant thinning and prominence that can result in vision defect. Due to ultrasonic changes in the corneal structure caused by keratoconus disease, its rigidity and biomechanical properties are subject to some changes. In this regard, the present study was conducted to determine the correlation of biomechanical feat...
Patients in intensive care units (ICU) are at increased risk of corneal abrasions and infectious keratitis due to poor eyelid closure, decreased blink reflex, and increased exposure to pathogenic microorganisms. The aim of this retrospective study was to evaluate the ocular surface problems in patients who stayed in ICU more than 7 days and were consulted by an ophthalmologist. There were 26 me...

METHODS This was a retrospective study of seven patients with Kearns-Sayre syndrome who had a minimum of 1 year of follow-up. A bilateral fascia lata sling was used to corr...
AIMS To report the appearances of cornea guttata and Fuchs' endothelial dystrophy from white light confocal microscopy. METHODS Seven eyes of four consecutive patients with cornea guttata were prospectively examined. Of the seven eyes, three also had corneal oedema (Fuchs' dystrophy). In vivo white light tandem scanning confocal microscopy was performed in all eyes. Results were compared with...
Introduction & Objectives: In recent studies, the negative effects of smoking on different parts of body have been cleared. Nevertheless other negative effects of smoking are being investigated. One of those effects is central and peripheral nervous system problem. The aim of this investigation was comparison of Hoffmann (H) reflex latency of tibial nerve in male smokers and non smokers between...
Introduction: Aim of the study was to determine the efficacy of minor lateral tarsorrhaphy in conjunction with levator muscle recession in thyroid ophthalmopathic patients with severe lid retraction in order to correct the temporal flare in these patients Methods: In a before-after clinical trial study, 22 eyelids of 12 patients with severe lid retraction underwent surgery by this method and t...
Purpose: To investigate the postoperative surgical outcome of all patients undergoing strabismus surgery and its effect on palpebral fissure alteration. Methods: In this cross-sectional study, 58 patients, who underwent strabismus surgery at Amir-al-Momenin Hospital, Rasht, Iran from March 2018 to 2019, were investigated for the changes in eye deviation and palpebral fissure height (PFH) 1 and ...
Purpose: Some anesthetic drugs are known to have influence on circulation due hemorheological effects.We aimed investigate the possible effects of ketamin-xylazine anesthesia, which is extensively used inexperimental animal laboratories parameters.Materials and methods: Adult, male Wistar-Albino rats were divided into two as control (pre-anesthesia)and post-anesthesia (n=17). Ketamin-HCl/Xylazi...
