bilateral retrolental fibrous masses which appeared during the first six retrolental fibroplasia are almost indistinguishable, since one . of the retina. As fibrosis. retrolental fibrosis, whereas he found 36 per cent in and, in , 45 per cent; this seems to be exceptional however. The affection as a rule manifests itself. Retinopathy of prematurity (ROP), also called retrolental fibroplasia (RLF) and Terry syndrome, is a disease of the eye affecting prematurely born babies.

Examination of the retina of a premature infant is performed to determine how far the retinal blood vessels have grown the zoneand whether fibbrosis not the vessels are growing flat along the wall of the eye the stage. Both oxygen toxicity and relative hypoxia can contribute to the development of ROP.

In order to allow timely intervention, a system of monitoring is undertaken for infants at risk of developing ROP.

Retinopathy of prematurity Tibrosisalso called retrolental fibroplasia RLF and Terry syndromeis a disease of the eye affecting prematurely born babies generally having received intensive neonatal carein which oxygen therapy is used on them due to the premature development of their lungs.

Each case of ROP avoided by withholding oxygen “may fjbrosis cost some 16 deaths”. Patients with ROP, particularly those who have developed severe disease needing treatment are at greater risk for strabismusglaucomacataracts and shortsightedness myopia later in life and should be examined yearly to help prevent or detect and treat these conditions.

Normally, maturation of the retina proceeds in-utero, and at term, the medial portion Nasal retina of the retina is fully vascularized, while the lateral portion Temporal retina retrolentxl only incompletely vascularized. In fibrksis patients the appearance of the disease is less well described but includes the residua of the ICROP stages as well as secondary retinal responses. The past decade has shown a remarkable increase in what has been called “retrolental fibroplasia” in infants of premature birth.

Retinopathy of prematurity ROPpreviously known as retrolental fibroplasias RLF is a disease of the eye that generally affects premature babies receiving intensive neonatal care. These monitoring protocols differ geographically because the definition of high-risk fibrsois not uniform or perfectly defined.

Multiple factors can determine whether the disease progresses, including overall health, birth weight, the stage of ROP at initial diagnosis, and the presence or absence of “plus disease”.

firosis If blood vessels grow normally, ROP does not occur. This increase is proportional to the degree of prematurity and the lowness of the birth weight, and it is selective in its geographic locality.

Associated with the growth of these new vessels is fibrous tissue scar tissue that may contract to cause retinal detachment.
