Purpose: To study the incidence, patterns and risk factors of sight threatening ROP.
Methods: A hospital based prospective observational study was conducted from January 2019 to December 2019 at Indira Gandhi Medical College Shimla. 250 babies who fulfilled inclusion criteria’s were examined by an ophthalmologist at 3 weeks postnatal age. Baseline factors, systemic risk factors, and pattern of ROP were noted. Factors associated with sight threatening ROP including Type-1 ROP, Stage IV and V, were analyzed.
Results: Out of 250 babies screened 13.6% babies developed any type of ROP. The incidence of sight threatening ROP was 9.2%.Out of 23 babies with ST- ROP Type -1 ROP was seen in 20 (86.95%) and advanced ROP (stage IV and V) in 3(13%). Mean gestational age, birth weight and duration of oxygen exposure for sight threatening ROP were 29.9 weeks and 1.23 kg, 23.83 ± 9.722 days respectively. Septicemia and respiratory Distress Syndrome found to be significant risk factors associated with ST- ROP. Late presentation was main cause of stage 4 and 5 disease.
Conclusion: Low birth weight, lower gestational age and duration of oxygen used were basic factors associated with development of ROP but risk factors like RDS and sepsis were found to be significant and independent risk factors for ST-ROP. These risk factors should be prevented or babies having these risk factors should be followed up regularly and treated effectively to stop the progression of disease.
