ABSTRACT

Purpose:

To determine the horizontal corneal diameter, central corneal thickness, and axial length in premature infants.

Methods:

Infants with a birth weight of less than 2,500 g or with a gestation period of less than 36 weeks were included in the study. Infants with retinopathy of prematurity (ROP) were allocated to Group 1 (n=138), while those without ROP were allocated to Group 2 (n=236). All infants underwent a complete ophthalmologic examination, including corneal diameter measurements, pachymetry, biometry, and fundoscopy. Between-group comparisons of horizontal corneal diameter, central corneal thickness, and axial lengths were performed. Independent sample t-tests were used for statistical analysis.

Results:

Data was obtained from 374 eyes of 187 infants (102 female, 85 male). The mean gestational age at birth was 30.7 ± 2.7 weeks (range 25-36 weeks), the mean birth weight was 1,514 ± 533.3 g (range 750-1,970 g), and the mean postmenstrual age at examination was 40.0 ± 4.8 weeks. The mean gestational age and the mean birth weight of Group 1 were statistically lower than Group 2 (p<0.05). There were no significant differences in horizontal corneal diameter, central corneal thickness, and axial length between the two groups (p>0.05).

Conclusions:

The presence of ROP in premature infants does not alter the horizontal corneal diameter, central corneal thickness, or axial length. .
RESUMO

Objetivo:

Determinar o diâmetro horizontal corneano, a espessura corneana central e o comprimento axial de prematuros.

Métodos:

Crianças com peso de nascimento menor que 2.500 g ou idade gestacional menor que 36 semanas foram incluídas no estudo. Recém-nascidos com retinopatia da prematuridade (ROP) foram alocados no Grupo 1 (n=138), sem ROP foram alocados no Grupo 2 (n=236). Todos os bebês foram submetidos a exame oftalmológico completo, incluindo medida do diâmetro corneano, paquimetria, biometria e fundoscopia. O diâmetro horizontal corneano, a espessura corneana central e o comprimento axial dos grupos foram comparados. Teste de "Student" para amostras independentes foi utilizado na análise estatística.

Resultados:

Os dados foram obtidos a partir de 374 olhos de 187 crianças (102 meninas, 85 meninos). A idade gestacional média ao nascer foi de 30,7 ± 2,7 semanas (variação de 25 a 36 semanas). O peso médio ao nascer foi de 1.514 ± 533,3 g (variação de 750 a 1.970 g). A idade pós-menstrual média de exame foi de 40,0 ± 4,8 semanas. A idade gestacional e o peso médio do Grupo 1 eram estatisticamente inferiores aos do Grupo 2 (p<0,05). Não houve diferenças significativas no diâmetro horizontal da córnea, espessura corneana central e medidas de comprimento axial entre dois grupos (p>0,05).

Conclusões:

A presença de ROP em prematuros não altera o diâmetro da córnea horizontal, espessura corneana central e o comprimento axial. .
