K. Tuppurainen et al., OCULAR FINDINGS IN PREMATURELY BORN CHILDREN AT 5 YEARS OF AGE, Graefe's archive for clinical and experimental ophthalmology, 231(5), 1993, pp. 261-266
Fifty-eight prematurely born children (gestational age less-than-or-eq
ual-to 32 weeks) were studied at the age of 5 years, The ophthalmologi
cal examination was part of an extensive neurodevelopmental evaluation
. The eye study revealed significant hyperopia (greater-than-or-equal-
to +2.0) in 22.4%, myopia (greater-than-or-equal-to -1.0 D) in 8.6%. a
stigmatism (greater-than-or-equal-to 1.0 D) in 12.1%, and anisometropi
a (greater-than-or-equal-to 1.0 D) in 12.1%. The myopic refractive err
or was high in all of the cases: from -6.0 to -14.0 D. Manifest strabi
smus was found in 24.2% and significant visual impairment or blindness
in 6.9%. Optic atrophy and cicatricial retinopathy of prematurity wer
e the main causes for severe visual defects. In the randomly selected
full-term children of the same age, significant hyperopia was seen in
14.3%, astigmatism in 5.4% and strabismus in 1.8%. The pattern of the
eye findings was different in the preterm children compared with those
born at term.
