Rate of Post-traumatic Endophthalmitis with or without Injection of Balanced Salt Solution.

Purpose: In a study complementing a previous multicenter randomized clinical trial on prophylactic injection of intraocular antibiotics during primary repair of penetrating eye injuries (PEIs), we sought to determine whether needle entrance and injection of balanced salt solution (BSS), per se, could increase the rate of acute post-traumatic bacterial endophthalmitis (APBE).

Methods: Patients randomized to the BSS injection arm (n=167) of the Traumatic Endophthalmitis Trial, and eligible patients who had refused enrollment and received no intraocular injections during primary repair (n=111) were compared for the development of APBE.

Results: APBE occurred in 8 of 167 (4.

Free-floating pyogenic granuloma of the lacrimal sac.

The authors report a 13-month-old girl with chronic dacryocystitis, and history of three times probing and once inferior turbinate infracture. She underwent dacryocystorhinostomy due to failure of previous procedures. During surgery a free floating reddish mass was extracted from the lacrimal sac.

Causes of visual impairment among patients referred to a visual rehabilitation clinic in Iran.

Purpose: Epidemiologic evaluation and investigating the causes of visual impairment in any society is a matter of concern and has a direct effect on the country's health care planning. In this study we describe causes of low vision and blindness in Iranian patients referred to rehabilitation clinics for taking vision aids.

Methods: In this cross-sectional study, visual acuity was classified based on best-corrected visual acuity in the better eye according to the World Health Organization definition (blindness, visual acuity [VA] < 20 / 400; severe visual impairment, VA < 20 / 200-20 / 400; mild to moderate visual impairment, VA < 20 / 60-20 / 200).

Prevalence and causes of low vision and blindness in Tehran Province, Iran.

Objective: To determine the prevalence and causes of blindness and low vision selected population at Tehran province, Iran in 2006.

Methods: A population-based cross-sectional study was conducted in the rural and urban population of Tehran province, Iran. The study design was based on the World Health Organization (WHO) criteria and a pilot study.

Prevalence of diabetic retinopathy in Tehran province: a population-based study.

Background: To determine the prevalence and characteristics of diabetic retinopathy (DR) among Iranian patients with diabetes.

Design: population-based cross-sectional study.

Participants: patients with diabetes aged 25 to 64 years in Tehran province, Iran.

Topographic evaluation of relatives of patients with keratoconus.

Purpose: To evaluate topographic corneal changes in relatives of patients with keratoconus (KCN).

Methods: In a prospective study, 300 eyes of 150 relatives of 45 patients with KCN were evaluated. Complete slit-lamp examination, refraction, and corneal topography were performed for all eyes.

Four mutations (three novel, one founder) in TACSTD2 among Iranian GDLD patients.

Purpose: To perform a mutation screening of TACSTD2 in 13 Iranian Gelatinous Drop-like Corneal Dystrophy (GDLD) pedigrees. To assess genotype-phenotype correlations. To determine intragenic SNP haplotypes associated with the mutations, so as to gain information on their origin.

Prophylaxis of acute posttraumatic bacterial endophthalmitis: a multicenter, randomized clinical trial of intraocular antibiotic injection, report 2.

Objective: To evaluate the efficacy of intraocular gentamicin sulfate and clindamycin in the prevention of acute posttraumatic bacterial endophthalmitis following penetrating eye injuries.

Method: We conducted a multicenter, randomized, double-masked controlled trial of 346 eyes with penetrating eye injury. Following primary repair, eyes were randomized to intracameral or intravitreal injection of 40 microg of gentamicin sulfate and 45 microg of clindamycin (cases) vs balanced salt solution (controls).
