Ocular features other than retinopathy of prematurity in the pre-term infant.

218 premature infants born 1985-87 in Frederiksborg County were followed in the eye clinic, mainly due to the risk of developing retinopathy of prematurity (ROP). The median gestational age was 33 weeks, the median birth weight 1.750 g. ROP being analysed elsewhere, emphasis is on a) retinal haemorrhages (long-standing in 11) and vitreous bleeding (3 cases); b) the oval shape of the pre-term optic disc, considered a true finding and not merely an optical artifact; c) the pre-term presence of the optic disc cup, otherwise considered of about-term development; and d) refractive state, with myopia as a prevailing finding at post-conceptional ages shorter than 40 weeks. A shift towards hypermetropia became obvious after 2-3 months. Only 4 cases deserved the label myopia of prematurity, the criteria being early recording of ROP and persistent myopia (for more than 18-24 months).
