an idea of fuzzy reexivity of felbin's type fuzzy normed linear spaces is introduced and its properties are studied. concept of fuzzy uniform normal structure is given and using the geometric properties of this concept xed point theorems are proved in fuzzy normed linear spaces.

PURPOSE To evaluate a tele-education system developed to improve diagnostic competency in retinopathy of prematurity (ROP) by ophthalmologists-in-training in Mexico. DESIGN Prospective, randomized cohort study. PARTICIPANTS Fifty-eight ophthalmology residents and fellows from a training program in Mexico consented to participate. Twenty-nine of 58 trainees (50%) were randomized to the educa...

AIM To evaluate if broadening the criteria for retinopathy of prematurity (ROP) screening to include babies with gestational age ≥32 weeks and/or birth weight ≥1500 g, would have an impact on the number of babies diagnosed as having ROP. METHODS A prospective cohort study was carried out at the Aga Khan University Hospital, Karachi, Pakistan. Infants with gestational age ≤35 weeks or birth we...

OBJECTIVE To investigate the natural history of retinopathy of prematurity (ROP) in 506 extremely preterm infants born before 27 weeks' gestation in Sweden during a 3-year period. METHODS A national population-based study was performed in Sweden from April 1, 2004, to March 31, 2007. According to the study protocol, initial eye examinations were to be performed at postnatal week 5, and examin...

Objective To explore the etiology, incidence and methods to prevent and treat severe retinopathy of prematurity (ROP), which is rapidly becoming a threat to the vision of babies in areas of the world where increasing numbers of premature babies are surviving. Data sources The data used in this review were mainly from Medline and PubMed published in English. The search term was “retinopathy of p...

Purpose. To convey the need for a revised screening strategy for retinopathy of prematurity (ROP) for extremely low birth weight (ELBW) infants in China. Design. A retrospective longitudinal study. Methods. The medical charts of infants with a birth weight (BW) of less than 1 kg were reviewed. The infants were divided into three groups: group A, without ROP; group B, with ROP but not up to type...

Purpose Retinopathy of prematurity (ROP) is the leading cause of blindness in children worldwide. This study aimed to determine the incidence and perinatal risk factors for ROP in very low-birth-weight (VLBW) Chinese infants. Methods A retrospective study of the medical records of 504 VLBW infants screened for ROP from 2012 to 2015 was performed in West China Second University Hospital. VLBW ...

BACKGROUND The aim of this study was to identify the incidence of severe retinopathy of prematurity (ROP) requiring laser treatment and the overall incidence of ROP in extremely low birth weight (ELBW) infants, and to evaluate the associated risk factors for developing severe ROP in ELBW infants in Turkey. MATERIAL AND METHODS This retrospective, case-control, tertiary care-hospital based stu...

OBJECTIVE To identify nutritional and weight gain limitations associated with retinopathy of prematurity (ROP) severity among very preterm newborns. PATIENTS AND METHODS 1180 infants <28 weeks GA at birth with ROP examination results were grouped and analyzed by quartile of weekly total calorie, carbohydrate, protein, and lipid intake, as well as growth velocity between postnatal days 7 and 2...
