To investigate the effects of body mass index (BMI) on intraocular pressure (IOP) and ocular pulse amplitude (OPA).Totally 140 healthy individuals without any systemic diseases were included in study. BMI (kg/m(2)) was calculated for every individual. IOP OPA measured with Pascal Dynamic contour tonometer (DCT). Blood also along DCT. The patients divided into three groups according to as: Group1, BMI<25; Group2, 25≤BMI<30; Group3, BMI≥30. Mean values IOP, OPA, systolic blood (SBP) diastolic...

We present the case of a 31-year-old patient with toxic anterior segment syndrome (TASS) that developed after undergoing deep lamellar keratoplasty (DALK). She had keratoconus, and despite wearing hard contact lenses for many years in left eye, her vision deteriorated; therefore, DALK was performed on this eye. The preoperative visual acuity (VA) finger counting at 3 m. Routine using "big-bubble" technique. corneal entry incision hydrated end surgery, which terminated by air injection into...

Purpose: To evaluate causes and management of congenital corneal opacities (CCO) diagnosed in a tertiary care eye center to compare the data with previous study at same institution.Methods: Computerized medical records all patients Cornea Service Wills Eye Hospital (Philadelphia, PA) between January 1, 2007, December 31, 2015, were retrospectively reviewed.Children aged 12 years younger first visit included study.Patients' demographics, ocular diagnosis, laterality, associated abnormalities,...

Thymoquinone, one of the biologically active components black seed oil, has anti-inflammatory and antioxidant properties. We aimed to study effect thymoquinone on corneal neovascularization in rats compare its efficacy with that triamcinolone acetonide.Chemical cauterization cornea was performed silver nitrate/potassium nitrate sticks 40 eyes rats. An examiner blinded experiments scored intensity cauterization. Topical instillation 0.1%, 0.4%, acetonide continued for 7 days. The inhibitory...

In this study, we aimed to investigate ocular manifestations in patients with vitiligo. Sixty-one vitiligo were included the study. From who referred for examination dermatology and ophthalmology clinic, 57 without any systemic disease taken as control group. both groups, otorefractometry, keratometry, visual acuity test, intraocular pressure measurement, anterior segment, fundus examinations of eye slit lamp, Schirmer perimetry carried out. The mean age was 24.54 ± 11.90 years 23.03 8.72...

To evaluate the medium-term motor outcomes of three horizontal muscle surgery in patients with large-angle infantile esotropia.The charts 18 (> 55 prism diopters [PD]) esotropia who underwent bilateral medial rectus recession and one lateral resection were retrospectively reviewed. Preoperative postoperative deviations at last examination, overcorrections undercorrections, necessity additional surgery, follow-up durations recorded.The median age was 22 months (range: 10 to 168 months)....

To evaluate the effectiveness and predictability of arcuate keratotomy (AK) for post-keratoplasty astigmatism to present complications rate repeat procedures.Sixteen eyes from 14 patients were included. Paired 70-80° arc length AKs centred on steep axis carried out 0.5 mm within graft-host junction.
