The International Classification of Retinopathy of Prematurity Revisited

Retinopathy of prematurity is one of the commonest cause of blindness in sick neonates exposed to excessive oxygen following NICU admissions. The present study was thus conducted to assess the pattern and risk factors associated with incidence of retinopathy of prematurity.A retrospective record based study was conducted at tertiary care centre between 1st July 2017 to 30thMay 2020 were screened for ROP. Baseline characteristics and risk factors for ROP were assessed. The zone and stage of ROP were categorized as per the International classification of ROP along with iris neovascularisation and plus disease as per the revised international classification of retinopathy of prematurity (ICROP) preplus disease criteria. Data was entered in excel sheet and analysed using SPSS software version 20.Majority of neonates belonged to gestational age of 28 to 31 weeks (58.8%) and 51.2% neonates had birthweight of 1.5 to 2 kg. Male preponderance was observed with male: female ratio of 1.75:1. Amongst the various risk factors, the occurrence of ROP was highly significantly associated with gestational age and birthweight (p<0.01). Subgroup analysis revealed that aggressive posterior ROP (APROP) contributed significantly to Type I ROP in 11.1% (3) cases. And the observed difference in gestational age and birthweight between APROP and other cases of ROP were statistically highly significant (p<0.01).Early and timely screening of ROP for all high risk neonates especially low birth weight and neonates with small gestational age should be mandatory as these are the most significant risk factors associated with ROP in present study.

International Classification

Infants diagnosed with retinopathy of prematurity (ROP) are at risk for developing visual impairments. The International Classification of ROP (ICROP) developed the most useful tool available for communicating the location and extent of the condition, with three zones to describe the location and five stages to describe the extent.Despite current knowledge and treatment, however, 500 infants are blinded each year by ROP. Infants at highest risk are the smallest and most immature. The nurse must understand why and how ROP occurs and the forms of management used to treat ROP. This article reports on the incidence, pathophysiology, risk factors, screening, treatment, and long-term complications of ROP in the 1990s.
