Controlled study of ocular morbidity in school children born preterm.

Two hundred children who were of very low birth weight (VLBW) (1500 g or less) and 193 controls who were of normal birth weight (NBW) were examined at approximately 9 years of age. Binocular visual acuity of 6/6 or better was noted in 178 (89.5%) VLBW children and 189 (97.9%) NBW children. Visual morbidity was significantly higher among VLBW children. Strabismus was present in 38 (19%), cicatricial retinopathy of prematurity in 13 (6.5%), and optic atrophy in six (3%) children in this group. Children who were VLBW were also more myopic than the NBW controls. Optic atrophy was frequently associated with cerebral dysfunction. Regular assessments to identify ocular abnormalities in children who were VLBW are recommended.

Causes of loss of vision in congenital glaucoma.

Of 51 patients with congenital glaucoma, 13 had unilateral and 38 bilateral disease. Pressure was controlled at 8 to 24 mm Hg in 76 of the 89 affected eyes. Forty-one of these 76 eyes had visual acuity poorer than 6/15 (20/50); optic nerve damage as shown by visual field testing was the cause in 20, and medial opacities, including irregular corneal astigmatism, was the cause in 15. In only six eyes did the poor vision result from anisometropic amblyopia.

Aetiological survey of visually handicapped children in Northern Ireland.

A survey of visually h,ndicapped children in Northern Ireland identified 486 subjects aged 0 to 20 years on January 1, 1976, with a corrected visual acuity of 6/18 or less in the better eye. The prevalence of visual handicap was 81/100,000 of the population with an estimated ascertainment rate of 80%. Genetically determined diseases accounted for 51% of the cases. Birth hypoxia secondary to prenatal and perinatal complications was the second most important aetiological factor contributing towards visual handicap.

Late presentation of congenital ectropion of the eyelids in a child with Down syndrome: a case report and review of the literature.

Congenital eversion or ectropion of the upper eyelids is rare. Only 50 cases have been reported since the condition was first described in 1896. We encountered an additional case of congenital ectropion of the eyelids, which is also unusual because of its late presentation for treatment. This case demonstrates the unfavorable outcome of failure to treat this condition at birth and illustrates the association with Down syndrome. Our case is compared with the others reported in the literature.
