Schepens Retina Associates Foundation International Vitreoretinal Consultants The Retina and Surgical Treatments Diseases and Disorders of the Retina Innovation / Experience and Research / Training Clinical Studies ... Vascular Obstruction in the Eye Retinopathy Of Prematurity Retinopathy of Prematurity (ROP) is a disease of the retina, the light sensitive membrane covering the inside of the eye. It affects small prematurely born babies. It consists of abnormal retinal vessels that grow mostly in an area where normal vessels have not yet grown in the retina (Fig. 11). ROP is divided into stages 1 to 5. Stages 1 and 2 do not usually require treatment. Some babies who have developed stage 3 ROP require treatment. The treatment is usually performed either by laser or cryotherapy (freezing). Laser is more commonly used now than cryotherapy because of various advances in the laser treatment. The ROP in stage 3 that requires treatment is generally called threshold disease . The majority (95%) of the babies who require laser or cryotherapy develop threshold disease between 32 and 42 weeks after conception. The post-conceptional age is calculated from the presumed day of conception. The area of the retina affected by ROP is divided into three zones (Fig. 12). Zone 1 is most centrally located, and ROP develops in this zone in eyes whose retina is most underdeveloped. Disease in zone 1 is more severe compared with disease limited to zones 2 or 3. Timing is one of the important factors that make the treatment successful in ROP, because the disease can advance very quickly and delay in treatment often reduces the chances of success. The rapidly progressing ROP is called

Home Site TOC Site Search Outreach ... Go to See/Hear Archive from the Winter 98 issue Retinopathy of Prematurity by Kate Moss , Family Support Specialist, TSBVI Deafblind Outreach A disease that occurs in some premature babies, Retinopathy of Prematurity (ROP), also known as Retrolental Fibroplasia, is the growth of abnormal blood vessels in the retina that generally begins during the first few days of life and may progress rapidly to blindness over a period of weeks. This happens because the eye is rapidly developing during gestational weeks 28-40. The blood supply to the retina starts at the optic nerve at about 16 weeks and blood vessels grow out from there toward the edges of the retina until the time of birth. When a baby is born prematurely, this normal vessel growth stops and new abnormal vessels begin to grow. Over time this vessel growth produces a fibrous scar tissue which attaches to the retina and the vitreous gel that gives the eyeball its shape. This ring may extend 360 degrees around the inside of the eye. If enough scar tissue forms, it can begin to pull the retina, detaching it, and, in some cases,causing blindness. Ophthalmology Associates Homepage Although there has been a correlation made between premies who receive high levels of oxygen and ROP, there appear to be a variety of factors that may account for development of ROP. These include, in addition to birth weight and gestational age: elevated blood carbon dioxide levels, anemia, blood transfusions, intraventricular hemorrhage, respiratory distress syndrome, chronic hypoxia in utero, multiple spells of apnea or bradycardia, mechanical ventilation, and seizures. (Ophthalmology Associates Homepage, 1997) There are some who feel that exposure to bright fluorescent lighting in hospitals contributes to the development of ROP (Prevent Blindness in Premature Babies, 1997), but to date this has not been proven and many ophthalmologists strongly disagree with this theory (Ophthalmology Associates Homepage, 1997). The current thinking is that probably it is a combination of factors, some occurring in utero and some occurring after the baby is born, that lead to this outcome.

Retinopathy of Prematurity Understanding Retinopathy of Prematurity Richard L. Windsor, O.D., F.A.A.O. Laura K. Windsor, O.D., F.A.A.O. Published in Vision Enhancement Journal Retinopathy of Prematurity (ROP), originally called retrolental fibroplasia, was the leading cause of blindness in children in the 1940s and 1950s. It was first described in the medical literature in 1942 by Terry. In 1952, Campbell theorized that the condition was caused by the use of oxygen therapy to treat the immature lungs in premature infants. Today, we realize that oxygen is not the only factor in developing ROP. High levels of oxygen have been associated with ROP, but lower levels of oxygen may lead to more respiratory complications and death in premature infants. Better oxygen level monitoring has led to better control of the oxygen given to premature infants. Today, however, there is an increase in ROP due to the fact that neonatal care advances mean more low weight premature infants are surviving. Statistics ROP occurs in over 16% of all premature births. In babies weighing less than 1,700 grams at birth, over 50% will develop ROP. In the United States, over 2,100 children annually experience the complications of ROP. Of those estimates of 500 to 1,200 cases of new blindness or severe complications are reported. Studies have found that about 30% of infants with advanced ROP have 20/200 or less in their better eye.

Videos ABOUT US Healthcommunities.com Pressroom Bibliography 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.

Retinopathy of Prematurity Streaming Video Introduction Click here to choose a video format Retinopathy of Prematurity Detailed Explanation Retinopathy of prematurity (ROP) has been divided into five stages. Stages 1 and 2 customarily get better on their own. Some eyes, however, go on to Stage 3 retinopathy of prematurity. This happens when new blood vessels start to grow from the retina toward the center of the eye, forming a ridge between retina that has blood vessels in the back of the eye, and the retina that does not have blood vessels in the front of the eye. This difference in the blood vessels of the retina is because the premature baby has not had the time while in the womb to allow the blood vessels within the retina to grow all the way from the optic nerve in the back of the eye to the front of the eye. Stage 3 ROP Stage 3 ROP exists when these disturbing new blood vessels grow out from the ridge in the retina toward the center of the eye.

PHILADELPHIA, April 14, 1996 In a companion study to the National Eye Institute's clinical investigation of cryotherapy to prevent blindness in children with severe retinopathy of prematurity (ROP), Ophthalmologists at The Children's Hospital of Philadelphia have determined that children with severe ROP who received the surgical intervention had an approximate 10 percent loss of peripheral or side vision in their treated eye. This pilot study is the first long-term study of its kind and appears in the April issue of Archives of Ophthalmology. "We followed 8 preterm patients who received cryotherapy at approximately 12 weeks of age," said Graham E. Quinn, M.D., Associate Surgeon, Division of Ophthalmology at The Children's Hospital of Philadelphia. All of the babies enrolled received cryotherapy in one eye, leaving the other eye to serve as a control. Dr. Quinn and his associates at Philadelphia's Children's Hospital and Wills Eye Hospital then followed the patients, testing their vision on an annual basis. "Today, the children are able to see and read letters," said Dr. Quinn. "However, in a test of the child's ability to detect an object off to the side while the child looked straight ahead, we found a deficit in peripheral vision of approximately 10 percent," Dr. Quinn said.

NEI Home Cryotherapy for Retinopathy of Prematurity (CRYO-ROP) - Outcome Study of Cryotherapy for Retinopathy of Prematurity Purpose Background Description Patient Eligibility ... NEI Representative Purpose 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. Background 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 40 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 three decades, the number of babies at risk has increased 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.

What Is an Ophthalmologist? What Is an Optometrist? What Is an Optician? Videos ABOUT US Healthcommunities.com Pressroom Bibliography Treatment Treatment for ROP depends on the stage and degree of retinal findings. Generally, Stages I and II resolve on their own and only require periodic evaluation. Treatment is initiated when threshold ROP , stage III with certain qualifying signs, is seen. This means that the condition of the eye has degenerated to a point beyond spontaneous resolution and where vision is seriously threatened. The goal of treatment is to help reduce the risk of retinal detachment and dragging of the macula, which can severely impact vision. Laser photocoagulation is the most common treatment modality. A laser is directed to a designated spot to destroy abnormal vessels and seal leaks. The procedure usually is performed under general anesthesia because these infants are typically extremely premature and have multiple medical problems. Laser photocoagulation is the preferred method of treatment by surgeons, because there is little postoperative pain and swelling.

Conditions Home Macular Degeneration Diabetic Retinopathy Dry Eye Syndrome ... Services Search Selected by the sciLINKS program, a service of National Science Teachers Association. Treatment 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. ROP is classified in 5 stages, depending on the extent of the disease. Progression of the disease to later stages can lead to the formation of scar tissue in the

The internal surface of the back of the eye is lined by a tissue, called the retina. This tissue is equivalent to the film in a camera and is responsible for the initial formation of the visual image. This is then transmitted to the brain. In order to function, the retina requires a blood supply. The normal development of this blood supply for the retina starts at 16 weeks into a pregnancy and is completed by 36 weeks. If an infant is born prematurely, with the retinal blood vessel development incomplete, problems occur. Abnormal blood vessels may develop which can subsequently lead to bleeding and scar tissue formation. This may then stretch the retina pulling it out of position. Visual loss may result.
