Insights
This study found no significant correlation between birth weight and myopia in premature newborns. Myopia levels remained consistent across different birth weight groups in the assessed premature infants.
Area of Science:
- Ophthalmology
- Neonatology
- Pediatrics
Background:
- Myopia is a common refractive error with multifactorial causes.
- Premature newborns are at increased risk for various health complications, including visual impairments.
Purpose of the Study:
- To investigate the relationship between birth weight and the severity of myopia in premature infants.
- To determine if lower birth weight in premature newborns is associated with higher myopia.
Main Methods:
- A cohort of 90 premature newborns (180 eyes) with myopia was analyzed.
- Participants were categorized into two groups based on birth weight: Group I (580-1500g) and Group II (1501-2450g).
- Myopia was measured in diopters (D) and analyzed using regression analysis with Statgraphics software.
Main Results:
- No statistically significant relationship was found between birth weight and myopia in Group I (b = 0.003, p = 0.24).
- Similarly, no significant relationship was observed between birth weight and myopia in Group II (b = 0.008, p = 0.016).
- Mean myopia was -10.4 D in Group I and -9.4 D in Group II.
Conclusions:
- Birth weight does not appear to be a significant predictor of myopia severity in this cohort of premature infants.
- Further research is needed to understand the complex etiology of myopia in premature populations.
- These findings suggest other factors may play a more critical role in myopia development in premature babies.
Aim:
The relation between myopia and birth weight of premature newborns was assessed in this study.
Material And Methods:
There were 90 children (180 eyes) involved in the study, their birth weight ranged between 580 and 2450 g (mean 1698), and myopia ranged from -1.5 to -22.5 D (mean -9.8 D). Children were divided into two groups: group I: 38 children (76 eyes) with birth weight from 580 to 1500 g (mean 1158 g), group II: 52 children (104 eyes) with birth weight from 1501 to 2450 g (mean 2093 g). Mean value of myopia in group I was -10.4 D and -9.4 D in group II.
Results:
The results were assessed with Statgraphics software. The analysis of mean values regression showed no relation between myopia and birth weight in group I (regression coefficient b = 0.003, p = 0.24) and no relation in group II (regression coefficient b = 0.008, p = 0.016) at significance level alpha = 0.01.
