Retinal detachment after ocular trauma

Abstract Purpose To discuss the clinical characteristics and treatmentoptions for retinal detachment after ocular trauma Methods The various types of ocular trauma and the different types of retinal detachments occurring as a complication of ocular trauma will be presented and comapred with each other Results The surgical treatment options for retinal detachment after ocular trauma will be presented. Conclusion Due to the high variability of ocular traumata and the reulting high high variability in the type and extent of retinal detachments after ocular traumata, the decision on the type of surgical treatment will usually be rather indivudual according to the special clincal situation.

Predicting visual outcome following retinectomy for retinal detachment

Aim:To evaluate outcome following retinectomy surgery and to identify factors that predict visual outcome.Methods:This was a retrospective uncontrolled interventional case-series of patients who underwent retinectomy surgery at Moorfields Eye Hospital...

Blindness associated with midfacial fractures.

This study assessed the frequency of blindness associated with midfacial fractures and correlated this with the fracture pattern. A retrospective analysis of 49 patients admitted with midfacial fractures from January 1995 to March 1997 was performed to determine the presence of posttraumatic blindness. The medical and radiological records of the patients with blindness were reviewed for age and sex, cause of the injury, type of facial fracture, type of ocular trauma, and probable cause of the blindness. Ten of the 49 patients lost vision in one eye (20% of all midfacial fractures and 22% of midface fractures involving the orbit). The possibility of blindness associated with facial fractures was directly related to the severity of injury. Road traffic accidents were the most common cause. Blindness was attributable to traumatic optic nerve injury in seven cases and a ruptured globe in three cases. The high frequency of blindness associated with midfacial fractures in this series was attributable to the predominance of road traffic accidents as the major cause and absence of an obligatory seat belt law. Early diagnosis of the exact nature of the ophthalmic injury and treatment are important, and involvement of the ophthalmologist is mandatory.

Post-traumatic Proliferative Vitreoretinopathy: The Epidemiologfic Profile, Onset, Risk Factors, and Visual Outcome

The purpose of the study was to characterize the clinical development of proliferative vitreoretinopathy (PVR) after trauma in the human eye. A chart review was performed on the records of 1564 patients with ocular trauma seen at a large metropolitan hospital. The frequency, type of ocular trauma, time to onset, potential risk factors, and visual outcome for PVR were evaluated. Proliferative vitreoretinopathy occurred in 71 (4%) of 1654 injured eyes. Of these 71 injured eyes, 30 (42%) resulted from rupture, 15 (21%) from penetration, 13 (18%) from perforation, and 7 (10%) from confusion. Six (9%) were associated with an intraocular foreign body (IOFB). The frequency of PVR following perforation, rupture, penetration, IOFB, and contusion was 43%, 21%, 15%, 11%, and 1%, respectively. Overall, those eyes that developed PVR had a poorer visual outcome, with PVR being the primary reason for visual loss. The time from injury to onset of PVR was shortest after perforation (median, 1.3 months), followed by rupture (2.1 months), IOFB (3.1 months), penetration (3.2 months), and contusion (5.7 months). Vitreous hemorrhage was the strongest independent predictive factor for the development of PVR. A long, posteriorly located wound and persistent intraocular inflammation were also important risk factors for PVR. These results suggest that PVR is a common complication following a variety of ocular injuries, and that it is associated with a poor visual outcome. Its frequency, onset, and outcome are strongly dependent on the nature of the trauma. Specific high-risk groups are identified as candidates for more aggressive therapy.

Ocular trauma

Many types of ocular trauma can be diagnosed and treated in the primary care office, particularly if a slit lamp is available. Treatment for corneal abrasions consists of applying a cycloplegic medication, antibiotic ointment, and a patch (unless a corneal ulcer is suspected). Iritis can be treated with cycloplegics and topical corticosteroids; the prescribing physician should be familiar with the potential ocular side effects and complications. Hyphemas are treated with bed rest, topical atropine sulfate drops and topical corticosteroids, as well as measures to prevent rebleeding. A slit lamp, topical anesthesia, and a foreign-body spud greatly facilitate the removal of foreign bodies from the cornea. Acid and alkali burns should be irrigated until the pH is normal and then should be treated like a corneal abrasion. Lid lacerations must be repaired with care to preserve proper functioning of the lid. Ruptures of the globe are serious injuries requiring surgical repair and long-term follow-up.

Eye Injury in Sport

Eye injury sustained during sport is increasing in incidence worldwide, reflecting the rise in popularity of sport as recreation. It can account for up to 25% of severe eye injuries. This paper considers the historical context and demography of sports injuries, and the physical mechanisms and results of various types of ocular trauma in relation to sport. It reviews the specific problems associated with the sports considered to be most important in the epidemiology of eye injuries today. Certain sports, such as boxing, have an intrinsic risk of injury so high that some consider the sport should be banned. The risk of injury in many sports can be mitigated by changes in rules, such as the prevention of high sticking in ice hockey. Other sports with high risk of trauma could be made far safer with the widespread introduction of eye protection, and this applies especially to squash and badminton. The various types of eye protection are discussed. There is an urgent need to increase awareness of the risk of eye injury, to teach safe techniques, and to encourage the use of appropriate ocular protective wear in those at high risk of injury, especially the one-eyed.
