OBJECTIVES: Childhood cataract is a genetically heterogeneous eye disorder that results in visual impairment. The aim of this study was to identify the genetic mutations of connexin 50 gene among Iranian families suffered from autosomal dominant congenital cataracts (ADCC). MATERIALS AND METHODS: Families, having at least two members with bilateral familial congenital cataract, were selected for the study. Probands were evaluated by detailed ophthalmologist's examination, and the pedigree analysis was performed...

PURPOSE: To describe a case of traumatic wound dehiscence after deep anterior lamellar keratoplasty. METHOD: Observational case report. CASE REPORT: A 31-year-old man who had undergone deep anterior lamellar keratoplasty using big-bubble technique for keratoconus 3 months earlier presented to emergency room after blunt trauma.On examination, visual acuity was counting fingers at 2 m. The corneal graft wound dehisced from 12 to 3 o'clock (90 degrees) with localized suture ruptures, but the anterior chamber was deep and the Seidel test was negative...

PURPOSE: To evaluate the sensitivity of photoscreener Plusoptix S08 in screening strabismus. METHODS: Eighty-three consecutive patients were examined by a single expert to determine the type and amount of the deviation. Then photoscreening was done for all the patients via Plusoptix S08 photoscreener (Plusoptix GmbH, Nuremberg, Germany) on the same day, using the default software for referring the patients. RESULTS: The age range was between 6 months and 40 years...

PURPOSE: To evaluate anterior segment optical coherence tomography (AS-OCT) in the preoperative simulation of postoperative iris-fixated phakic intraocular lens (pIOL) position in the anterior chamber. SETTING: Farabi Eye Research Center, Department of Ophthalmology, Tehran University of Medical Sciences, Tehran, Iran. DESIGN: Case series. METHODS: Using AS-OCT, the pIOL position was simulated preoperatively in 2 ways and compared with the actual postoperative pIOL position...

PURPOSE: To investigate the association between senile corneal arcus and atherosclerosis risk factors in patients with recent acute myocardial infarction. METHODS: In this cross sectional study, atherosclerosis risk factors including fasting blood sugar, total cholesterol and triglyceride levels were measured in 165 patients with recent (less than three months' duration) acute myocardial infarction. Slitlamp examination was performed to detect corneal arcus. Associations between senile corneal arcus and atherosclerosis risk factors were assessed...

PURPOSE: To evaluate the clinical features, and visual outcomes of sterile uveitis after iris-fixated phakic intraocular lens implantation (pIOLs) (Artisan-Artiflex(®) and Verisyse-Veriflex(®)). MATERIAL AND METHODS: In this retrospective non-comparative case series, the medical records of 117 eyes implanted with Artisan-Artiflex(®) (Ophtec BV, Groningen, Netherlands) and Verisyse-Veriflex(®) (AMO, Santa Ana, CA) iris claw phakic IOLs were analyzed for postimplantation sterile uveitis...

Herein we describe a technique for management of large inadvertent full-thickness trephination during deep anterior lamellar keratoplasty using the big-bubble technique without converting to penetrating keratoplasty. First, the anterior chamber is formed with an ophthalmic viscosurgical device (OVD). Then, the full-thickness wound is secured with one X-type 10-0 nylon suture. A 27-gauge needle is attached to a 2 ml air-filled syringe and inserted into the corneal stroma in the meridian opposite to the site of full-thickness trephination...

AIMS: To evaluate the accuracy and applicability of Plusoptix photoscreener in screening pre-verbal children at risk of amblyopia. METHODS: In this cross-sectional population-based study 996 children aged 6-36 months were screened with the Plusoptix. The children underwent complete examinations that included a manual cycloplegic retinoscopy, slit lamp examination, cover test, the Hirschberg test and an assessment of fixation pattern. In addition, the prevalence of amblyogenic risk factors was estimated, the Plusopix measurements were compared with cycloplegic retinoscopy, and the referral criteria were modified to improve the accuracy of the device...
