Abstract
INTRODUCTION: The word ―TRAUMA‖ which derived from Greek word – meaning ― WOUND. Ocular injuries are the major cause of visual impairment. Eye injuries are the major cause of preventable blindness and visual impairment leads to economical, psychological, social problems to the patient. In adults, the incidence of ocular injuries has increased with occupational related injuries, road traffic accidents, sports injuries, agricultural vegetable matter injuries, household chemicals can also causes ocular injuries. According to Birmingham Eye Trauma Terminology System (BETTS), practicing ophthalmologists documenting ocular trauma cases in a standardized manner, which provides simple, unique, comprehensive system to describe the mechanical injuries to the globe. Open globe injuries showed good prognosis due to the timely intervention and various newer microsurgical instrumentation techniques. AIM OF THE STUDY: This study aims to evaluate the posterior segment manifestations and visual outcome. MATERIALS AND METHODS: This Prospective study will be conducted at Vitreoretina department, RIOGOH, Egmore, Chennai for a period of 12 months. RESULTS: 30% shown in the age group of above 50 yrs. Males are most commonly affected in this study about 78%. Self accidental injuries has showed 38% among RTA and work place injuries.76% of cases were reported as closed globe injuries. Right eye involvement is about 56% left eye showed 40%. Time interval between the injury and presentation to the hospital was studied, which showed immediate presentation (56%) is most common. Among the posterior segment injuries retina is most commonly involved. Involvement of 62% vitreous haemorrhage is more common than other vitreous changes. In the retina retinal detachment showed 54.17% than other retinal changes. Risk of developing choroidal detachment about 60%. choroidal tear showed 40%. In the optic nerve 4 cases 8% showed traumatic optic neuropathy. 2% showed post traumatic endophthalmitis. Macular edema showed 24 cases and 3 cases of macular holes. Medical management itself showed better visual outcome than surgical treatment. Here 56% of cases were medically managed. 38% surgically managed. On follow up period 52% showed improvement in vision. 28% were maintained the same vision in the follow up period also, remaining 18% showed reduced visual out come due to irregular follow up interval, cataract lens changes. Above 50 years of cases showed good improvement in follow up vision about 37.0%, since most common presentation seen in this age group. Male patient showed improvement in final visual outcome 74.1%, than females.it was not statistically significant. (P- 0.257). Right eye showed 55.6% of final visual outcome than others. Since, Involvement of right eye is more in our study. Here there is no statistically significant comparison between the laterality and visual outcome. Patients when presented immediate after the trauma, showed improvement in outcome in 55.6% P-0.04 which is statistically significant. CONCLUSION: Management of ocular injuries should form a part of general trauma care for restoring potential visual acuity. Creating ocular awareness regarding the prevention and safety measurement to prevent injury in schoolchildren and industrial workers. Males being the breadwinners of the family in our society. Earlier presentation, timely intervention, regular follow up can improve the visual prognosis of the patient.
