Changing patterns in retinopathy of prematurity

Area of Science:

• Ophthalmology
• Neonatology
• Pediatrics

Background:

• Improved survival rates for premature infants over the past two decades.
• Previous studies indicated varying incidences of retinopathy of prematurity based on birth weight.
• Need to reassess current incidence due to changing survival demographics.

Purpose of the Study:

• To determine the current incidence of cicatricial retinopathy of prematurity in a cohort of premature infants.
• To compare current findings with data from a decade prior.
• To analyze the relationship between birth weight and the development of retinopathy of prematurity.

Main Methods:

• Prospective examination of 197 consecutive premature infants.
• Regular follow-up examinations until 6 months of age.
• Categorization of infants based on birth weight (<1,000 g, 1,001–1,250 g, >1,250 g).

Main Results:

• Changes affecting visual acuity were observed in 22% of infants <1,000 g birth weight.
• Incidence was 10% for infants between 1,001–1,250 g and 0% for those >1,250 g.
• A significant reduction in the overall incidence of retinopathy of prematurity was noted compared to a decade ago.

Conclusions:

• Despite a reduced incidence, the increasing survival of profoundly premature infants may lead to a rise in the absolute number of retinopathy of prematurity cases.
• Continued monitoring and management strategies are crucial for surviving premature infants.
• Birth weight remains a critical factor in assessing the risk of developing retinopathy of prematurity.
