Aim: This study aims to investigate the neovascularization-inhibiting effect of topical nilotinib and determine effective dose nilotinib.
 Material Method: In this study, 42 healthy Wistar albino rats were randomly divided into six groups. The left corneas all except group 1 cauterized with silver nitrate. Group was control, no corneal vascularization, which did not receive any treatment; ...
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...
PURPOSE To determine whether measurable preoperative characteristics predispose patients to chronic dry eye after laser in situ keratomileusis (LASIK). METHODS The study consisted of 24 eyes of 24 patients who underwent LASIK. Tear breakup time, Schirmer testing with and without anesthesia, rose bengal staining, central corneal sensitivity, nucleus-to-cytoplasmic ratio, and goblet cell densit...
The present form of the Mackay-Marg tonometer consists of a 1.5 mm. diameter fat-based plunger mounted essentially flush with a flat footplate. The rubber mounting of the plunger acts as a stiff spring. Pressure measurements are derived from intraocular pressure acting through the flattened cornea against the plunger and causing microplunger movements. It has been shown that the response of thi...
Ocular morbidities are quite common phenomenon in elderly patients due to lack of immunity and associated diseases like Diabetes mellitus, HTN which result into blindness. also influenced by their location, habits medical history. This study is attempted the pattern ocular morbidity understand risk factors responsible for visual impairment. It a hospital based cross sectional where 300 &#62...
In the current study, we conducted a mutation screening of tumor-associated calcium signal transducer 2 (TACSTD2) gene in six consanguineous Iranian families with gelatinous drop-like corneal dystrophy (GDLD), in order to find the causative mutations. Detailed eye examination was performed by ophthalmologist to confirm GDLD in patients. To detect the possible mutations, direct Sanger sequencing...
The purpose of this study was to evaluate the effects of different time combinations of dexamethasoneand acetylcysteine on experimentally induced corneal ulcers in dogs. Experimental corneal wounds werecreated surgically to the anterior one third of the cornea in the center of all eyes of 15 mixed breed dogs. The eyes were divided into five groups according to planned post-operative medications...
purpose: to study the effect of phototherapeutic keratectomy (ptk) in the treatment of various superficial corneal pathologies. methods: we performed a nonrandomized, prospective study on patients who presented with superficial corneal disease and/or poor vision. fifty eyes were included recurrent corneal erosion (rce): 25 eyes, salzmann’s nodular degeneration: 9 eyes, spheroidal degeneration: ...
purpose: congenital corneal leukoma is rare with an incidence of 6/100000 and is one of the most important causes of amblyopia. here we report an unusual case of bilateral congenital elevated corneal leukoma. methods: we encountered a 13-day-old full term male newborn. ocular examination of both eyes revealed central elevated corneal leukomas with a narrow normal lucid interval to limbus. corne...
