Comparison of Three Vision Therapy Approaches for Convergence Insufficiency.

Purpose: We compared the effectiveness of three active vision therapy approaches for convergence insufficiency (CI).

Methods: This randomized clinical trial included patients meeting the eligibility criteria and with symptomatic CI, who were allocated into three groups. In the home-based vision orthoptic therapy (HBVOT) group, patients performed the pencil push-up procedure 15 min/day for 5 days/week.

Infantile Periocular Hemangioma.

Infantile periocular hemangiomas (IPH) are common benign vascular tumors that present early in childhood. They typically show a rapid nonlinear growth pattern a few weeks after birth during a proliferative phase, then continue with an involution phase and may result in serious ocular or systemic complications. Theses tumors may present in a range of small isolated lesions to multiple, diffuse involvements.

Oculocardiac Reflex during Strabismus Surgery: Experience from a Tertiary Hospital.

Purpose: To evaluate the incidence of the oculocardiac reflex (OCR) and its associated risk factors during strabismus surgery at a tertiary referral center.

Methods: Over a 2-year period, all strabismus surgery candidates were enrolled in the study. OCR was defined as heart rate reduction ≥15% after traction on extraocular muscle(s).

Genetic polymorphisms of vascular endothelial growth factor and risk for retinopathy of prematurity in South of Iran.

Retinopathy of prematurity (ROP) is a multifactorial disease, that cause visual impairment in premature children. The exact pathogenesis and etiology of ROP is unknown and genetic susceptibility is considered as risk factor. Vascular endothelial growth factor (VEGF) plays a major role in retinal neovascularization and subsequently retinal detachment.

The use of mersilene mesh for wrapping of hydroxyapatite orbital implants: mid-term result.

Purpose: To report the results of Mersilene mesh wrapped hydroxyapatite orbital implantation.

Materials And Methods: Records of 63 patients operated between April 2002 and March 2006 were retrospectively reviewed. Parameters studied included sex, cause of enucleation, length of follow-up after operation, implant exposure, secondary implantation, and surgeon experience.

Superior oblique tendon expansion with Achilles tendon allograft for treating Brown syndrome.

Purpose: To report the results of treatment of Brown syndrome using Achilles tendon allograft as a superior oblique tendon expander.

Methods: Achilles tendon allografts were prepared from the tissue bank. Five eyes of 3 patients with congenital Brown syndrome (mean age, 6 years) were enrolled in the study.

Effect of Fas -670 A/G gene polymorphism on corneal allograft endothelial rejection.

Background: Human cornea expresses functional Fas-ligand capable of killing Fas+ activated lymphocytes. Fas expression is partly regulated by -670 A/G polymorphism in the promoter region of Fas gene.

Objective: The aim of the present study is to determine the association between Fas-670A/G polymorphism and survival of corneal transplantation.

Role of internal sphincterotomy in the treatment of hemorrhoids: a randomized clinical trial.

Background: Anal canal dilatation and sphincterotomy have been recommended besides hemorrhoidectomy to overcome the anal pressures in the management of hemorrhoids. The aim of this study to compare internal sphincterotomy and hemorrhoidectomy with hemorrhoidectomy alone with respect to manometric and clinical measures.

Methods: One hundred twenty patients with hemorrhoids were randomly assigned to receive either hemorrhoidectomy with sphincterotomy or hemorrhoidectomy alone.

The effect of season and Ramadan fasting on the onset of acute cholecystitis.

Objective: To investigate whether Ramadan fasting and seasonal variation has any effect on the onset of acute cholecystitis.

Methods: A cross-sectional study was conducted in Faghihi and Namazee Hospitals between September 1999 to August 2004. All files of patients with definite diagnosis of gallstone induced acute cholecystitis were reviewed for age, gender, date and method of treatment in relation to seasons and Ramadan fasting month.
