This study was to report the incidence of ROP and characteristics of premature infants who developed Type I ROP in a tertiary maternity hospital in Kazakhstan.
Kazakh Eye Research Institute, Astana - Kazakhstan Perinatal Centre #1 Astana
The patients for this study were recruited at Perinatal Centre #1 in Astana city (a tertiary maternity hospital). The criteria for ROP screening of premature infants in Kazakhstan were following: - BW ≤ 2000 g; - GA ≤ 34 weeks. ROP screening was performed according to the UK Retinopathy of Prematurity Guideline and ROP was graded following the revisited ICROP (2005).
From January 2015 to October 2016, 473 premature infants were fully screened for ROP. Mean GA was 30,5±2,8 weeks, mean BW was 1202,5±281,5g. Incidence of any ROP was 27,3% (129), Type I ROP – 4,3% (43). Any stage ROP was noted in 85%, 32,3%, 5,1% in infants with GA ≤27 weeks, 28-31 weeks, ≥32 weeks respectively. Any stage ROP was noted in 78,3%, 39,1%, 4,0% in infants with BW <1000g, 1000-1500g and ≥1501g respectively. Type I ROP was noted in 43,3%, 7,4% in infants with GA ≤27 weeks, 28-31 weeks respectively. No any Type I ROP in infants with GA≥32 weeks. Type I ROP was diagnosed in 34,9%, 8,7%, 0,8% in infants with BW <1000g, 1000-1500g and ≥1501g respectively. Transpupillary diode laser therapy was performed in all case with Type I ROP. Mean GA in this group infants was 26,3±2,2 weeks, BW -938,7±348,9gr. Mean GA at the time of laser therapy was 36,4±3,3 weeks. APROP was developed in 2 infants.
Extremely premature infants were found to be more likely to develop severe ROP. Smaller BW and GA were associated with the increased incidence of ROP, including severe forms requiring timely surgical intervention.
