Retrolental fibroplasia (RLF) affects 33.8% of high-risk infants. Key risk factors include prematurity, apnea, and sepsis, necessitating early eye exams for survivors.
Area of Science:
- Neonatal ophthalmology
- Perinatal medicine
- Pediatric critical care
Background:
- Retrolental fibroplasia (RLF) is a serious eye condition affecting premature infants.
- Understanding RLF's risk factors is crucial for preventing vision loss in vulnerable newborns.
Purpose of the Study:
- To identify determinant factors associated with the occurrence of RLF in a cohort of surviving low birth weight infants.
- To analyze the incidence and risk factors for active and cicatricial RLF.
Main Methods:
- Retrospective analysis of 80 infants born between 1975-1976 with birth weights of 501-1500 gm.
- Statistical analysis to determine significant associations between clinical factors and RLF development.
- Ophthalmologic follow-up examinations to assess for myopia.
Main Results:
- RLF occurred in 33.8% of infants; severe RLF in 10%.
- Significant risk factors included gestational age, apnea requiring resuscitation, septicemia, illness severity, blood transfusion, and mechanical ventilation.
- A strong association was found between RLF and severe myopia in follow-up.
Conclusions:
- A resurgence and high incidence of RLF in surviving low birth weight infants were observed.
- Infants with identified risk factors require vigilant monitoring and ophthalmologic evaluation.
- Recommendations include pre-discharge and post-discharge eye examinations to detect RLF and myopia early.
Abstract:
Possible determinant factors that may increase the risk of the occurrence of retrolental fibroplasia (RLF) were analyzed in 80 infants born in 1975 and 1976 with birth weights between 501 and 1,500 gm and who survived. Active and/or cicatricial RLF occurred in 27 (33.8%) infants and the factors significantly associated with RLF were: gestational age (P less than .001); apnea requiring bag and mask resuscitation with oxygen (P less than .001); septicemia (P less than .005); degree of illness; blood transfusion; and mechanical ventilation. Severe cicatricial RLF developed in eight (10%) infants (grades 2 to 5). In the group of infants all of whom had apnea which required resuscitation, septicemia was also significantly associated with RLF (P less than .01). A highly significant association between RLF and severe myopia (P less than .001) was found in follow-up in all infants. Data show a resurgence and high incidence of RLF in low birth weight infants who survived. Infants with these factors should be considered to have greater risk for the occurrence of RLF and ophthalmologic examination prior to, and within three months following discharge is recommended.
