Purpose: To evaluate the safety and efficacy of femtosecond laser-assisted MyoRing implantation with concurrent corneal collagen crosslinking (CXL) compared to MyoRing alone for the treatment of progressive keratoconus.
Methods: A total of 60 patients were enrolled in this randomized controlled trial. The patients were randomly allocated into two groups.
Purpose: To evaluate the efficacy of topical tacrolimus 0.05% as adjuvant therapy to corticosteroids in the treatment of acute endothelial rejection of a penetrating keratoplasty (PKP) graft.
Methods: Patients with the clinical diagnosis of acute endothelial rejection of a PKP graft were randomized into 2 groups-group 1: receiving topical tacrolimus 0.
Background: To compare the efficacy of subconjunctival administration of bevacizumab and different doses of sunitinib malate in reducing corneal neovascularization (CNV).
Materials And Methods: In this experimental study, central corneal cauterization was created in the right eye of fifty male Sprague-Dawley rats. On day 1 (1 week after cauterization), rats were randomly assigned into five treatment groups.
Bacterial keratitis in a tertiary eye centre in Iran: a retrospective study.
Middle East Afr J Ophthalmol
August 2015
Purpose: To report the characteristics and laboratory findings of 182 patients with bacterial keratitis diagnosed at Farabi Eye Hospital in Tehran, Iran.
Materials And Methods: In this retrospective study, data were collected on demographics, risk factors, location, size and depth of the ulcer, height of the hypopyon, uncorrected visual acuity, results of smear and culture tests, and antibiotic sensitivity of cultured bacteria.
Results: There were 110 (60.
Purpose: To compare the visual, refractive, and keratometric outcomes of single-segment conventional and severe keratoconus (SK) types of Intacs for correction of inferior keratoconus (KCN).
Methods: A total number of 41 consecutive eyes of 23 patients with a diagnosis of inferior KCN underwent Intacs implantation. Eight eyes were excluded due to postoperative complications (4 eyes) and loss to follow-up (4 eyes) and finally 33 eyes underwent statistical analysis.
Aim: To evaluate the efficacy and safety of botulinum toxin type A (Dysport, (Ipsen Biopharm Ltd, Wrexham, UK)) injection in patients requiring temporary tarsorrhaphy to improve corneal epithelial defects.
Methods: Thirty patients were enrolled into the prospective study between March 2007 and September 2009. Doses of 15 and 30U of Dysport were injected into the levator palpebrae superioris muscle through the eyelid.
Purpose: To evaluate clinical outcome(s) and complication(s) of topical bevacizumab (avastin) in patients with impending recurrent pterygium.
Patients And Methods: This prospective clinical trial included 54 consecutive patients (54 eyes), who underwent pterygium surgery with bare sclera and mitomycin, and who were diagnosed with impending recurrent pterygium. Of the 54 patients, 26 received eye drops containing bevacizumab (5 mg/ml) twice a day and betamethasone four times daily for 1 week.
Background: We describe corneal endothelial cell density and morphology in normal Iranian eyes and compare endothelial cell characteristics in the Iranian population with data available in the literature for American and Indian populations.
Methods: Specular microscopy was performed in 525 eyes of normal Iranian people aged 20 to 85 years old. The studied parameters including mean endothelial cell density (MCD), mean cell area (MCA) and coefficient of variation (CV) in cell area were analyzed in all of the 525 eyes.
