purpose: this study aimed to evaluate risk factors associated with threshold retinopathy of prematurity (rop) in premature infants referred to farabi eye hospital during 2008-2009. since blindness and sever visual impairments will occur in a high percentage of infants stricken with threshold retinopathy, we intended to examine relationship between demographic factors and threshold retinopathy i...

purpose : to evaluate the structural outcomes of treated neonates with retinopathy of prematurity (rop) methods : in this cross-sectional study from april 2008 to august 2009, 859 patients were investigated. these neonates had been consulted at the retinal clinic of farabi eye hospital of tehran university of medical sciences. those with gestational age of no more than 36 weeks and birth weight...

The new diagnostic threshold of hemoglobin A(1c) was made based on evidence from cross-sectional studies, and no longitudinal study supports its validity. To examine whether hemoglobin A(1c) of 6.5% or higher defines a threshold for elevated risk of incident retinopathy, we analyzed longitudinal data of 19,897 Japanese adults who underwent a health checkup in 2006 and were followed up 3 years l...

Glycated hemoglobin (HbA1c) has recently been recommended for the diagnosis of type 2 diabetes mellitus (T2DM) by leading diabetes organizations and by the World Health Organization. The most important reason to define T2DM is to identify subjects with high risk of diabetes complications who may benefit from treatment. This review addresses two questions: 1) to assess from existing studies whet...

OBJECTIVE To evaluate the prevalence of retinopathy of prematurity and the risk factors affecting very low birth weight infants at a neonatal intensive care unit. METHODS A cross-sectional study investigating all newborn infants with birth weights < or = 1,500 g and/or gestational ages < or = 32 weeks, admitted to the Neonatal ICU at the Hospital de Clínicas de Porto Alegre, from October 2002...

In a retrospective study in preterms treated with either cryotherapy (n= 16, 2000-2001) or laser photocoagulation (n= 19, 2002-2005) for threshold retinopathy, a significant decrease in duration of postoperative ventilation, in postoperative administration of analgesics and in time until regain of full enteral feeding was documented in infants who received laser photocoagulation. We therefore c...

We investigated the association of serum homocysteine levels and vitamin status with type 2 diabetic retinopathy. This study included 65 patients with and 75 patients without diabetic retinopathy. Patients with diabetic retinopathy had significantly higher serum homocysteine levels (P < 0.001), higher prevalence of hyperhomocysteinemia (P < 0.001), lower serum folic acid (P < 0.001), and vitami...
