Prematurity: Heavy Retinal Damage by Immature
October 15th 2009 -
Extreme prematurity ever have better chances of survival owing to the progress in the medicine. Early baby into the world however, by, suffer the more frequently they come from heavy visual disturbances, as Scandinavian researchers discovered now. The reason is that the blood vessels in the retina (retina) could not develop the preemies correctly, writes the scientists around Dr. Dordi Austeng, lady doctor at the University hospital in the Swedish Uppsala and at the University hospital in Trondheim (Norway). The study was published in the specialist journal “Archives of Ophthalmology (2009, 127 (10): 1315-1319).
For children the investigation the researchers analyzed the data of 506 extremely preterm – before the 27th Pregnancy week were born. 368 babies (scarcely 73 per cent) exhibited one in the immature retina damage caused: Somewhat more than half (37.9 per cent) had an easy, the remainder (34.8 per cent) a heavy retinopathy.
The risk for such eye damage hung Thereby less of the birth weight rather than gestational age of the off thus the time interval, which spent a child in the mother body. “The occurrence of the retinopathy fell from 100 per cent with the five children, who came into the world after 22 weeks, with those on 56 per cent, to end of the 26th Week in the mother body, “study chief Austeng thus remained. Each additional gestation thus reduced the risk for damage to the retina.
Earlier investigations had resulted in substantially lower ratios for retinopathy in the case of heavy earlyborn than the 34.8 per cent in the new study: Thus Belgian researchers on approximately 26 per cent, Austrian scientists had come on 16 per cent. So Austeng has an explanation for it: To the current studies participated many more extremely premature babies than in earlier. “These extremely immature children, who would not have survived at all still some years ago, are probably particularly in the long run and heavy susceptibly to complications such as retinal damage due to the immaturity.”
