Males are four times more likely than females to have ocular injuries, and eye injuries occur mostly among persons in their 20s or younger. However, as the population ages, we are seeing an increasing number of eye injuries in the elderly. Most injuries occur in the home, are sports-related or workrelated or are the result of an assault or result from a motor vehicle accident. The most common objects to strike the eye are fists, thrown objects (e.g., stones, balls), BBs, pellets and sticks. Older individuals often suffer ocular trauma after falling down. Assault and motor vehicle injuries are usually the most severe and may cause so much damage that the eye must be removed. TYPES OF INJURY Contusions and abrasions are the most common types of injury. The injured eye may present as a black eye due to bleeding under the skin and into the soft tissues that surround the eye. The eye may be painful, particularly if the cornea has been scratched or has a foreign body in it. Vision may be reduced if there is bleeding into the eye or from damage to the retina. Double vision may Contusion occur due to a fracture of the bones that support the eyeball or due to hemorrhage around the eye. Penetrating eye injury requires immediate referral because of the risk of devastating ocular infection. Such injuries are most commonly seen in children at play with sharp objects. This type of injury can occur from a shattered windschield in road traffic accidents and from high velocity missiles at the workplace. Foreign bodies are most frequently found on the cornea and under the eyelid where they can be easily removed. We have seen a progressive increase in eye trauma resulting from automobile accidents in the past seven years. Frontal air bag deployment was associated with a statistically significant, two-fold increased risk of eye injury, whereas seat belt use was associated with a two-fold reduced eye injury risk. Seat belt use is the most effective means of occupant protection against automobile accident-related eye injury. Older age, being female, passenger seat position and collision severity were also associated with eye injury risk. EYE PROTECTION Many cases of ocular injury can be prevented by wearing protective eyeglasses. Many sports-related and occupational injuries can be prevented if appropriate, properly fitted, taskspecific eye protection is worn. Sports injuries account for approximately 100,000 eye injuries each year. These are so common because millions of Americans play sports, but few wear the appropriate eye protection. Eye and head protection should be worn by persons playing lacrosse, football, squash, racquetball or paint ball war games. CONCLUSION One can reduce the risk of ocular injury by being aware of those activities that increase the risk of injury and by taking the necessary precautions to minimize or eliminate that risk. CORNEAL INJURIES The cornea is the clear covering of the eye. It is a very delicate structure that must remain smooth and clear for perfect vision. Because of the external location of the cornea, when the eyelids are open, the cornea is subject to many different types of trauma. The cornea contains more nerve endings than nearly any other part of the body. This means that when a healthy cornea is injured—even a tiny scratch—it hurts! Three main categories of corneal trauma include corneal abrasions, corneal lacerations and corneal infections. continued on page 2 eyelights page 2 CORNEAL ABRASIONS The cornea has three layers. The outside layer of the cornea, the layer closest to the outside environment, is made up of clear epithelium, or skin. When this epithelium gets scratched, it is called a corneal abrasion. Accidental injury of the cornea (e.g., a small baby reaches up with his or her fingernail; a coat hanger or the edge of a piece of paper is moved quickly in front of the eye) is very common. When this occurs, symptoms include eye pain, blurry vision, redness, tearing and the “feeling” that something is in the eye. The pain is often more noticeable when the eye is open, and subsides, somewhat, when the eye is closed. To diagnose a corneal abrasion, an ophthalmologist will often use a numbing drop, to temporarily relieve the pain and allow for an examination under the microscope. A yellow-colored drop is also often used to temporarily stain the cornea and allow for the correct diagnosis. It should be noted that the numbing drop used in the office should never be given to a patient for pain relief because continued use of such a drop will slow down the healing process. Although the discomfort of a corneal abrasion is significant, inappropriate use of the diagnostic numbing drops can result in permanent and severe vision loss. Because the cornea has so many nerve endings, it heals quickly. Common treatments of corneal abrasions include antibiotic eye drops or ointments to protect the eye from infection; patching the eye closed if the original scratch was not caused by something dirty; or use of a “bandage” contact lens, in more severe cases. CORNEA LACERATIONS A cornea can become lacerated if a foreign object cuts into the substance of the cornea. If there is a high velocity sharp object (e.g., a nail, broken glass, a small rock), the object may tear through the cornea and enter the eye. A corneal laceration is a medical emergency and usually requires immediate medical care and possibly surgery by an ophthalmologist. If corneal trauma is witnessed, and an object is seen “stuck” to the cornea, never attempt to remove the object yourself. Doing so may cause more damage to the eye. Emergency medical care should be sought and only an eye care professional should remove the object. CORNEAL INFECTIONS If a cornea is injured by something “dirty,” it is not uncommon for the cornea to become infected. Common causes of corneal infection after trauma include eye injuries by plants, leaves, sticks or thorns; scratches by the paws of pets; scratches that occur while sleeping in or swimming in contact lenses; or clean scratches that took a long time to heal, and became infected later. Corneal infections are very serious and can cause permanent visual loss if not appropriately diagnosed or treated. It is common for the cornea to become injured in the setting of trauma. Corneal injuries should be evaluated promptly and treated by your ophthalmologist. GLAUCOMA CAUSED BY TRAUMA TO THE EYE Ocular trauma may cause problems that can usually be corrected during the post-traumatic period. These include removal of a foreign body from the cornea or eyelid, repair of any lacerations or damage to the eye and tissues around it, treatment for intraocular bleeding, and warm compresses to help the black and contused eye look and feel better. However, damage may occur to the delicate channels that regulate the flow of normal intraocular fluids. These channels, called trabecular meshwork, are important because they let fluid escape from the eye as fast as new fluid is produced, thereby keeping the intraocular pressure at a normal level. Anything that damages or clogs this trabecular meshwork will cause the intraocular pressure to rise and produce glaucoma. In time, the glaucoma may cause loss of vision and lead to blindness. INFLAMMATION Trauma to the eye is likely to stimulate inflammation in and around the eye, a natural process that ordinarily helps the eye to heal. But in some cases, the inflammatory white cells may be so numerous that they clog the channels (trabecular meshwork) and lead to a buildup of intraocular pressure and glaucoma. HEMORRHAGE Blunt trauma to the eye can occur if it Hyphema, blood in the is hit by a hand or fist, when the eye is lower part of the anterior chamber struck by a flying object or missile, or when the eye is struck during a fall. This sudden blow can cause bleeding around the eye (contusion) or in the eye (hyph-ema, hemorrhage). This mass of red blood cells can then clog the trabecular meshwork (channels) and block the flow of the natural fluids in the eye. This can cause a rapid rise in intraocular pressure and glaucoma. In many cases, the blood will resorb and disappear in days to weeks. If the eye pressure climbs too high or the blood fails to resorb, then it may be necessary to remove the blood clot in the eye. DAMAGE TO THE OUTFLOW CHANNELS (TRABECULAR MESHWORK) Even when there is no hemorrhage, trauma to the eye can cause permanent damage to the trabecular meshwork. This can produce a gradual rise in the intraocular pressure that may take weeks, months or years to develop. For that reason, it is important to be regularly checked, at least yearly, following trauma to the eye. TREATMENT Inflammation in and around the eye can be effectively treated with warm compresses and eye drops that decrease the intraocucontinued on page 3 eyelights page 3 lar inflammation. Elevated intraocular pressure and glaucoma can be effectively treated with conventional glaucoma eye drops. In some cases, the intraocular pressure may be so high that it cannot be reduced by glaucoma eye drops or other medication, and surgical intervention may be required. However, the best treatment is prevention of the ocular trauma before it happens. RETINAL DETACHMENT AFTER EYE TRAUMA Eye injuries can happen just about any time and in every conceivable setting. One of the most significant factors in the severity of the injury is whether or not eye protection (safety glasses, sports goggles) is present. Other important factors include the energy involved in the injury and the mechanism of impact. A high-energy, high-velocity impact with a sharp object will generally mean a worse prognosis for the eye than a low-energy impact with a blunt object. Common settings in which eye injuries occur are sporting/leisure activities, working with lawn or shop equipment, military combat, and physical assault. Injury to the retina is more likely to occur with high-risk, highenergy impact injuries. The retina is an extremely delicate and sensitive layer of nerve tissue that lines the inside of the eyeball, receiving light and images that are focused through the lens of the eye. Like film inside a camera, the retina records images and Sadie Feldman T he department of Ophthalmology at Sinai and all of the members of the Krieger Eye Institute (KEI) will miss Sadie Feldman who died last September. She was a great friend of the KEI and left behind a legacy for which her entire family will be remembered and admired. Her death marks the end of an era when she, her brother, and her sister, Rossetta Feldman Glashofer, were all part of the KEI family. Sadie’s brother was a native of Virginia, although he was reared and educated in Baltimore, where he attended the Johns Hopkins University and the Maryland Institute College of Art. In his early years he practiced his artistic skills by submitting several political cartoons to the local newspapers. He started a successful advertising firm that was located in downtown Baltimore. But his real love was collecting Americana, specializing in furniture and decorative arts relating to Baltimore and to Maryland. His collection was installed in his home, a century-old house built on the original John Eager Howard estate. He shared many of the treasures in his collection by placing them on indefinite loan to the local museums. sends the information back to the brain, where higher order visual processing occurs, leading to our subjective perceptions of the world around us. The retina is essentially the gateway that turns light into sight by sending images to the brain. Blunt impact injuries can briefly deform the eye ball, changing its shape much like a tennis ball when it strikes a firm surface. This traumatic “squeezing” of the eye ball can create tears in the delicate retinal lining of the eye, leading to bleeding and detachment of the retina from its normal position snug against the eyewall. If untreated, this can lead to permanent blindness. Retinal injury can also occur with sharp penetrating objects like nails, glass and chips of metal. Common symptoms of retiTraumatic retinal detachment nal tear and bleeding include new floaters, flashes of light and blurry vision. In cases of early retinal detachment, a dark shadow can be seen in the side vision. It is very important to receive a full eye examination after eye injury. Early detection of traumatic retinal injury and bleeding can be the deciding factor in restoring vision and avoiding permanent visual loss. Sadie graduated from the Johns Hopkins University and the Maryland Institute of Art and received a master’s degree in psychology at the George Washington University. She returned to Baltimore where she and her brother, Samson, maintained an active interest in art and collecting Americana. They inherited their father’s penchant for collecting rare Americana, leading to an outstanding collection of furniture and decorative arts. Sadie Feldman, like her brother and sister, was devoted to the arts and took an active interest in those Baltimore institutions that preserved them. Her philanthropy rewarded not only the Baltimore Museum of Art and the Walters Art Gallery, but also other institutions and programs such as the Jewish Historical Society and the Department of Art in Medicine at the Johns Hopkins Hospital. But most important, Sadie, with her sister, endowed the Samson Feldman Library, one of the largest collections of ophthalmology texts and journals in Baltimore and used by community medical personnel, ophthalmology residents and staff. Sadie also provided for the Feldman Family Lectureship at the Krieger Eye Institute. She attended each program and personally greeted each Feldman lecturer. This lectureship serves as a memorative tribute to this wonderful family. Sadie was a person with a multitude of interests and she excelled in everything she tried. She was a gentle, kind and generous person. We shall remember her because of the many wonderful and important contributions that she made to this department and the art community of Baltimore. eyelights page 4 Donald Abrams, M.D. Named New Chief of Ophthalmology Dr. Donald A. Abrams becomes the third Zanvyl Krieger chairman of Ophthalmology and the latest ophthalmologist-in-chief at Sinai. He follows Dr. Irvin Pollack who was the first director of the KEI and served for 15 years before stepping down. Dr. James Karesh was the second director and left the position in June 2005. Dr. Abrams assumes the mantle at a time of rapid change within the department (see articles about Residency and about Faculty). Before 1983, Ophthalmology at Sinai was a division of the Department of Surgery when Dr. Herman Krieger Goldberg was chief. No stranger to the department, Dr. Abrams served as an Ophthalmology resident at Sinai before coming onto the full-time staff in 1989. He received fellowship training in glaucoma at the Doheny Eye Institute, the University of Southern California School of Medicine. After joining the Sinai faculty, he became director of the M arc Hirschbein M.D. Named Associate Chairman of KEI Dr. Donald Abrams, ophthalmologistin-chief and Zanvyl Krieger chairman of Ophthalmology appointed Dr. Marc Hirschbein as associate chairman of Ophthalmology. Dr. Hirschbein is a Baltimore native who graduated with general honors from the University of Maryland and received his M.D. from Hahnemann University School of Medicine in Philadelphia. He served as both intern and resident in Ophthalmology at the Krieger Eye Institute (KEI) of Sinai Hospital during which time he became interested in oculoplastics. He had his fellowship in Oculoplastic Surgery at Glaucoma Service and received national recognition as a glaucoma specialist and surgeon. He is assistant professor of Ophthalmology at the Johns Hopkins University School of Medicine, an outstanding lecturer and has over 30 publications in peer-reviewed journals. Dr. Abrams has devoted much of his career to teaching and resident education. He has served as director of Graduate Medical Education at Sinai, the Departmental Committee and the Medical Records/Health Information Management Committee. For many years, he served on the Residency Selection Committee and Ophthalmology Residency Integration Committee. Among his teaching awards are the Wilmer-Sinai-GBMC Resident Advocate Award and the Golden Globe Teaching Award. As chief of Ophthalmology, Dr. Abrams plans to move the department forward by expanding opportunities for the Institute. “I hope to expand the Krieger Eye Institute’s coverage area by looking into opportunities for growth at Northwest Hospital Center and other areas in Pikesville, Mount Washington and Owings Mills, Maryland.” Albany Eye Physicians and Surgeons and Albany Medical Center before coming to Sinai. Since 1999 he has been a member of the oculoplastic surgery team at the KEI and has taken an active role in the continued development and expansion of the department. Dr. Hirschbein has developed a keen interest in all aspects of ophthalmic plastic and reconstructive surgery, but has a particular interest in laser research and its use and benefits in plastic surgery around the eye. He is a member of the National CyberKnife Protocol Steering Committee and is secretary of the Maryland Society of Eye Physicians and Surgeons. He has published more than 18 book chapters and papers in peer-reviewed journals. His major research interest includes studies with the Cyberknife, eyelid retraction repair with a new porcine dermal implant and use of mitomycin-C for punctoplasty. New KEI Ophthalmology Residents Dr. Anthony Castelbuone, KEI’s program director, noted that resident education is not a new activity of the Krieger Eye Institute. After a wonderful 10 years participating as a sponsoring institution in a combined residency with the Johns Hopkins n December, the Krieger Eye Institute met with more than Wilmer Eye Institute and the GBMC Department of 40 medical students from around the country who were Ophthalmology, Krieger re-formed its own residency this past each competing for one of two spots in the newly re-formed fall. “It was the first Accreditation Council for Graduate Sinai Hospital Ophthalmology Residency Program. The Medical Education approved new residency program in many applicants were chosen from over 100 highly qualified medyears,” according to Dr. Castelbuono, “and we are honored to ical students who applied for the chance to interview.

A social event was organized for Judging from the high quality of our applicants and their excitement out-of-town visitors in the Inner Harbor, where they had opportunity to meet our current residents and talk to the faculty. They seemed high- for our program,” Dr. Castelbuono added, “we look forward to working with two new residents who will begin in July 2007. Together with ly interested in what Krieger had to offer, namely a very high level of our attendings, we are certain they will continue to provide a high level on-site training by board certified and fellowship trained specialists in of patient care for the Northwest Baltimore community.” all the subspecialty areas of ophthalmology.

Even though most states have restricted the types of fireworks available to the general public, there are still 12,000 fireworks-related injuries a year in the United States. About 20% of these, or about 2,400 injuries, are to the eye. About half of these eye injuries result in legal blindness, and about 5% result in loss of the eye (or necessitated removal of the eye). The statistics are grim. About 3/4 of these eye injuries occur in children. The average age was 15, but 5- to 9-year-olds had the highest injury rate. Most of the injuries to children under age 5 are from sparklers. According to the United States Eye Injury Registry, about 3/4 of the injuries occur during the Fourth of July holiday. More than half of those injured are bystanders, and 3/4 of those injured are male. The bottle rocket (illegal in Maryland) causes most of the injuries. This is the firework with the long thin stick attached. It is designed to be placed in a bottle before the fuse is lit. continued on next page Papers and Chapters Published: Hirschbein M, Karesh J, Yassur Y: Ectropion and Entropion in Step by Step Oculoplastic Surgery, ed.

Two million people suffer eye injury every year in the United States. 8. Most eye injuries occur in young men under 20 years of age. The cornea has more nerve endings than nearly any other part of the body. Therefore, even a tiny scratch in the cornea will cause terrible pain. Blunt trauma to the eye (such as from a fist or rock) can cause hemorrhage in the eye or retinal detachment and lead to blindness. Most states in the United States have restricted the types of fireworks available to the general public. Even so, there are 2,400 injuries to the eye from fireworks every year and 1/2 of these result in blindness. Three quarters of all firework injuries occur in children.
