Development of grating acuity in infants with Retinopathy of Prematurity

Abstract

ABSTRACT.Purpose: To evaluate the visual development in infants with stage 1∂3 ROP and compare their visual results with healthy preterm infants. Patients and Methods: One hundred forty-four premature infants were recruited and were divided into 3 groups according to the stage of ROP. Randomly selected preterm subjects with no ROP were taken as controls. Ophthalmic examinations started 4 to 7 weeks after birth and were repeated as needed until the retina was fully vascularized or until any ROP that developed had resolved.

“…Such a mechanism was reproducible in the laboratory by obstruction of blood flow. More recently papilloedema has been reported with central retinal vein occlusion [ 7 ] and has even been reported unilaterally due to vasospasm (optic vein migraine) after vaccination [ 8 ]; however, compression of the central retinal vein in experimental models does not result in disc oedema [ 9 ]. The other general mechanisms of papilloedema that have been evoked to explain its appearance in COPD and CHF as noted above [ 2 ] are explained by the autoregulative mechanism or its breakdown through hypercapnia, tissue anoxia or severe hypertension [ 11 ].…”

“…Lebensjahr in allen Altersstufen gegenüber Termingeborenen reduziert ist [38,58]. Einige Studien fanden einen funktionellen Unterschied zwischen Augen mit und ohne RPM [31,76], andere Studien dagegen nicht [30].…”
