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...

PURPOSE We investigated longitudinally the refraction development in children with regressed retinopathy of prematurity (ROP), including those with and those without a history of peripheral retinal laser photocoagulation. METHODS Longitudinal (0-7 years) cycloplegic refraction data were collected prospectively for two groups of preterm children: severe ROP group included those with regressed ...

PURPOSE To evaluate scotopic retinal organization in retinopathy of prematurity (ROP) through a study of spatial summation. METHODS Thresholds for a range of stimulus diameters (0.4°-10°) were measured using a two alternative, spatial, forced choice psychophysical procedure. The critical diameter (DCRIT) for complete summation was estimated in subjects with a history of severe ROP (N = 7) and...

PURPOSE This study aimed to evaluate the outcome of transpupillary diode laser photocoagulation for retinopathy of prematurity (ROP) at one institution in Romania. METHODS This retrospective case series included all infants who received indirect diode laser photocoagulation for ROP between January 1, 2006, and December 31, 2012. RESULTS The 160 eyes of 83 infants were classified into two ca...

Retinopathy of prematurity (ROP) is one of the most important causes of childhood blindness worldwide. The trend of ROP in Malaysia was unclear because there was no national registry before 2002. The purpose of this study is to analyze ROP students of different ages in the schools for the blind in Malaysia in order to evaluate the trend of ROP from 1992 to 2001. Data were obtained from a previo...

The aim of our study was to measure and compare serum insulin-like growth factor-1 (IGF-1) levels at postmenstrual age of 33 weeks between preterm infants with and without retinopathy of prematurity (ROP). ROP occurs in two phases. Low serum levels of IGF-1 during ROP phase 1 have been found to correlate with the severity of ROP. ROP phase 2 begins around postmenstrual week 33. We conducted a p...

PURPOSE To describe Type 1 retinopathy of prematurity (ROP) and its laser treatment outcomes in premature infants with birth weight > 1250 g in Eastern China. METHODS A retrospective review of 3175 ROP records was conducted at Shanghai Eye & ENT Hospital of Fudan University. The records were collected at the ROP clinic from 2006 to 2014, including their demographic and medical information suc...

OBJECTIVES To investigate the incidence, severity and risk factors of retinopathy of prematurity (ROP) in triplets. MATERIALS AND METHODS The medical records of consecutive premature triplets who had been screened for ROP in a single maternity hospital were analyzed and presence and severity of ROP; birth weight, gender, gestational age of the infant; route of delivery and the mode of concept...
