Extractions: Autumn 2000 Retinopathy of Prematurity (ROP) is an important cause of childhood blindness that can be screened for and treated with some success. The sequelae of untreated or non-responsive ROP can be devastating and may often be associated with other disabilities, and so steps to limit the condition are of vital importance for the individual children concerned, for their families and for the healthcare system that provides for them. Definition and Classification Threshold ROP is 5 contiguous clock hours of stage 3 retinopathy in zones I or II (8 clock hours or more if not contiguous), in the presence of 'plus' disease (dilated retinal arterioles and congested veins, abbreviated as '+'). If untreated, it is associated with a poor anatomical outcome in approximately 50% of cases. Pre-threshold ROP is usually defined as any retinopathy in zone 1, or Stages 2+ or 3 in zone II. Stage 3 ROP has a greater likelihood of an anatomically unfavourable outcome if present in the zone 1 (59% poor outcome)than in zone II (44% poor outcome if stage 3+, <1% if no '+' or stage 2). The degree (or lack of) vessel development when first seen and the presence or not of dilated iris vessels, are also both related to the likelihood of a poor outcome, independently of birthweight or gestation.

http://www.visionchannel.net/retinopathy/

Extractions: Overview Retinopathy of prematurity or ROP (formerly known as retrolental fibroplasia) is the abnormal growth of blood vessels within the retina and vitreous that occurs in some premature infants. Abnormal blood vessel growth (neovascularization) does not deliver nutrients to the retina; rather, it is associated with significant disease as the blood vessels are fragile and prone to leak. The progression to later stages of ROP can lead to the formation of scar tissue on the retina, vitreous hemorrhage, and retinal detachment Many infants who have early ROP improve spontaneously. The severity of ROP varies, ranging from nearly normal vision to total blindness. Signs of ROP are found in very premature babies and one in ten progresses to more severe stages. Typically, the smallest and earliest premature babies are at the highest risk for developing ROP. Incidence and Prevalence

http://www.visionchannel.net/retinopathy/causes.shtml

Extractions: Causes The human eye develops rapidly between 28 and 40 weeks gestation. The blood supply to the retina begins to form at about 16 weeks gestation, starting at the optic nerve. Blood vessels grow from the optic nerve toward the edges of the retinaa process that continues until the fetus reaches term. When a baby is born prematurely, normal blood vessel development may cease and abnormal growth may begin. Supplemental oxygen use is likely associated with development of ROP. Signs and Symptoms There are no symptoms of ROP and infants must be screened by an ophthalmologist. Screening is recommended for all premature infants (born at less than 35 weeks gestation or who weighed less that 1800 grams) who received supplemental oxygen, and

About The Cochrane Library A substantive amendment to this systematic review was last made on 13 November 2000. Cochrane reviews are regularly checked and updated if necessary. Background: Retinopathy of prematurity (ROP) causes vision loss in many premature infants each year, despite the advances being made in treatment. In the search for ways to prevent the disease altogether, the exposure of the retina to bright ambient light following premature birth has been a natural hypothesis, since the premature infant normally would be in the dark in-utero environment. Several controlled studies have now addressed this theory. Objectives: To answer the question: "Among very low birth weight infants, what is the effect of reducing early environmental light exposure on the incidence of any "Acute ROP", or "Poor ROP Outcomes"? Search strategy: Searches were made of the Cochrane Neonatal Group Register of Controlled Trials, Medline, EMBASE, the Cochrane Library, previous reviews including cross references, abstracts, conference and symposia proceedings, and expert informants.

Hemorrhagic Shock And Encephalopathy Syndrome Retinopathy Of Prematurity (Retrolental Fibroplasia) A bilateral ocular disorder of abnormal retinal vascularization in premature infants, especially those of lowest birth weight, with outcomes ranging from normal vision to blindness. Because the inner retinal blood vessels start growing about midpregnancy and have fully vascularized the retina by full term, their growth is incomplete in premature infants. Retinopathy of prematurity (ROP) results if these vessels continue their growth in an abnormal pattern. Susceptibility to ROP varies but correlates with the proportion of retina that remains avascular at birth. increases the risk of ROP, but a threshold safe level or duration of elevated Pa is not known. Symptoms, Signs, and Prognosis An abnormal ridge of tissue forms between the vascularized central retina and the nonvascularized peripheral retina. In severe ROP, these new vessels invade the vitreous, and sometimes the entire vasculature of the eye becomes engorged ("plus" disease). The abnormal vessel growth often subsides spontaneously but, in about 4% of survivors weighing < 1 kg at birth, progresses to produce retinal detachments and vision loss within 2 to 12 mo postpartum. Children with healed ROP have a higher incidence of myopia, strabismus, and amblyopia. A few children with moderate, healed ROP are left with cicatricial scars (eg, dragged retina or retinal folds) but no initial retinal detachments and are at risk for retinal detachments later in life.

When an infant is born very prematurely, the infant's eye development will be disrupted. In infants who develop retinopathy of prematurity (ROP), the vessels grow abnormally from the retina into the normally clear gel that fills the back of the eye. Here, without support, the vessels are fragile and often hemorrhage into the eye. This is followed by scar tissue development which pulls the retina loose from the inner surface of the eye and draws it toward the center of the globe, producing a retinal detachment. This can reduce vision or, if severe, result in complete

Extractions: Retinopathy of Prematurity Overview Retinopathy of Prematurity (ROP) , also known as retrolental fibroplasia, is a potentially blinding condition affecting the retina of newborns. In the 1950's it was associated with the use of high amounts of oxygen in neonatal units. Today, modern neonatal care has curbed the incidence, yet because the survival rate of low birth weight infants is much higher, the exposure of surviving babies to required oxygen levels is increasing. The factors that put infants at greatest risk of developing ROP are low birth weight (less than 3.5 pounds) and premature delivery (26-28 weeks). In babies born prematurely, the growth and development of normal blood vessels in the retina is halted and abnormal vessels may begin to develop. The problem with abnormal vessel growth, known as neovascularization, is that it does not deliver adequate oxygen supply to the retina. In addition, it may cause many secondary problems.

http://www.pedseye.com/RoP.htm

Extractions: Prematurity Retinopathy of prematurity or ROP is a retinal disorder found exclusively in premature infants. The incidence of ROP increases for younger and smaller babies. It is normally not seen in infants weighing more than 1500 grams or about three pounds five ounces. With ROP, the normal blood vessels of the retina, which is the nerve tissue in the back of the eye, do not complete their growth until the end of a normal full term pregnancy. In very small babies, the blood vessels may stop growing when they are born. When they resume their growth, it can be in an abnormal fashion which causes damage to the retina. A screening examination schedule has been determined to aid in detecting ROP and prevent its progression when possible. Eye examinations are usually performed in the hospital nursery with the use of eye drops to dilate the pupils so that the retina can be examined. If any ROP is found, follow-up evaluations are recommended over the following weeks at intervals determined by the stage of the disease. In most cases, the ROP will resolve spontaneously as the blood vessels complete their growth pattern. In some cases, the ROP reaches a certain stage for which treatment becomes necessary. This treatment is in the form of laser therapy to the retina. It has been shown that treatment at a certain stage of ROP can decrease, though not eliminate the chances of retinal damage and subsequent poor vision.

Extractions: Prematurity (ROP) is an eye disorder affecting premature infants. This disorder was called Retrolental Fibroplasia in the past. ROP affects immature blood vessels of the retina. It occurs weeks after birth. Once development of blood vessels is complete, a child is no longer a candidate for this disorder. As pictured in the graphic of the retina below: Zone I is centered on the Macula (which is the area of central vision needed for reading). Zone II refers to an area that is doughnut shaped that extends to the edge closest to the nose. Zone III refers to the crescent shaped area toward the ear. If disease appears in Zone One (as can happen with extremely low birthweight infants), damage to the retina tends to be more severe. If Zone Three is affected, the premature infant will tend to have mild involvement, leading to useful vision. The suggested causes of Retinopathy of Prematurity are those conditions which stop the orderly growth of retinal blood vessels and stimulate their wild overgrowth.

Extractions: Retinopathy of Prematurity ... Retina Services Retinopathy of Prematurity The last 12 weeks of gestation is a very active growth period for the fetal eye. At 16 weeks of gestation the blood supply to the retina starts at the optic nerve. Gradually vessels grow out over the surface of the retina and stop at about the time of birth. The normal retinal vessel growth is delayed in premature infants. Retinopathy of prematurity (ROP) is a spectrum of findings associated with immature retinal vasculature. ROP is more common in low weight infants (less than 1500 grams) with significant medical problems. Most babies with ROP actually "outgrow" their eye problem as the retinal vasculature matures. A minority of babies (7%) with ROP ever necessitate treatment. Laser treatment, when indicated, significantly decreases the risk of severe retinal damage in ROP. ROP screening retinal exams are routine at newborn intensive care units for low weight premature babies.

NEI Representative To determine the safety and efficacy of trans-scleral cryotherapy of the peripheral retina in certain low birth-weight infants with retinopathy of prematurity (ROP) for reducing blindness from ROP. To determine the long-term outcome for eyes that had severe ("threshold") ROP, both with and without cryotherapy. ROP is a disease of the eyes of prematurely born infants in which the retinal blood vessels increase in number and branch excessively, sometimes leading to hemorrhage or scarring. Before the establishment of this study in 1985, more than 500 infants annually were blinded by ROP in the United States alone. More than 30 years ago, the National Institutes of Health sponsored a clinical trial that showed that if premature babies are given oxygen only as needed, the number of infants who develop ROP drops dramatically. Subsequently, hospitals cut back on giving excessive oxygen routinely to premature babies. But, with improvements in neonatal care over the last two decades, the number of babies at risk is increasing as survival rates for smaller premature infants improve. The lower the birth weight, the higher the incidence and severity of ROP. In a more recent NEI-supported study at the University of Miami, blood oxygen levels of very low birth-weight infants were monitored continuously by use of transcutaneous measurements as long as oxygen therapy was needed. The study showed that there is no statistically significant difference between the rates of ROP in infants monitored on continuous oxygen therapy and in those monitored only when they were receiving oxygen in excess of 40 percent.

Extractions: CS Home Search for a Study Participate in a Study Refer a Patient to a Study ... NEI Home Purpose Background Description Patient Eligibility ... NEI Representative To evaluate the effect of ambient light reduction on the incidence of retinopathy of prematurity (ROP). Despite progress during the past decade in treatment of ROP, this disease still poses a significant (approximately 2.1 percent) risk of blindness to extremely low birth-weight ( <1,251 grams) preterm infants. Current estimates indicate that about 27,000 infants of extremely low birth weight are born annually, of which 74 percent will survive. As techniques of managing smaller and less mature preterm infants continue to improve, it is expected that the number of infants at risk for blindness will continue to increase. For infants weighing less than 1,251 grams at birth, the Cryotherapy for Retinopathy of Prematurity (CRYO-ROP) Study has shown that the risk of developing severe, acute (threshold) ROP is 6 percent. Although cryotherapy, when applied at the time of threshold ROP, reduces the rate of unfavorable visual outcome, 35 percent of eyes that develop this level of severe, acute disease are blind 1 year after treatment. Moreover, cryotherapy is destructive. Even when cryotherapy prevents progression to retinal detachment, it is associated with peripheral retinal destruction and may, in some cases, be associated with subnormal central vision due to high myopia and/or macular scarring. Corrective surgical treatments for retinal detachment caused by ROP have proven to be of little visual benefit. A preventive treatment for ROP that is safe, efficacious, easily applied, and inexpensive is desirable.
