Abstract:
AIM: To explore the clinical value of 25 - gauge vitrectomy in the treatment of traumatized eyes with non-light perception.?METHODS:Forty-six patients (46 eyes) who diagnosed as traumatized eyes with non-light perception treated with 25-gauge vitrectomy, which collected in our hospital from July 1, 2013 to June 1, 2017. Their sex, age, residence area, traumatic nature, causes of injury, duration from the injury to intervention, location and size of the wound, visual acuity and prognosis was retrospectively studied and analyzed statistically in this study.?RESULTS: In the 46 patients, 38 were males, 8 were females (M :F= 4. 75:1). The age of the patients was between 7 and 77 years ( mean 37. 96 ± 18. 99 years). Among them, there were 26 case ( 57％) in the young group (<45 years ) , 14 case ( 30％) in the middle age group ( 45-60 years ) , 6 cases ( 13％) in the older age group (>60 years ) . The cause of injury included blunt trauma ( 18 cases, 39％) , sharp instrument injury ( 8 cases, 17％) , plant injury ( 6 cases, 13％) , explosion injury (6 cases, 13％), impact injury (4 cases, 9％), limb impact injury ( 2 cases, 4％) , traffic accident injury ( 2 cases, 4％) . There were 33 cases ( 72％) with ocular rupture, 12 cases (26％) with perforating injury of eyeball and 1 case ( 2％) with ocular contusion. There were 44 cases (96％) with vitreous hemorrhage, 30 cases (65％) with retinal detachment, 18 cases ( 39％) with intraocular foreign body (IOFB), 22 cases (48％) with cilio-choroidal detachment, 18 cases (39％) with endophthalmitis and 12 cases (26％) with retinal hemorrhage. The postoperative best-corrected visual acuity improved to light perception or better than light perception in 30 cases ( 65％) , and 16 cases (35％) still had no light perception.? CONCLUSION: The patients who had no light perception after ocular trauma were almost young and middle- aged people in rural areas. The factors that affected the visual acuity of the postoperative included the type of injury, the location and size of the wound, the retinal detachment, the cilio-choroidal detachment, the duration from the injury to intervention, the endophthalmitis and whether the merger of intraocular foreign body or not. The 25-gauge vitrectomy could make most of the visual acuity from no light perception to light perception or over the light perception, which had a high clinical value in curing traumatized eyes with no light perception.
