ABSTRACT
Objective To investigate the effect of retinectomy 360? for severe ocular rupture and evaluate the related factors associated with prognosis. Methods We retrospectively analyzed 28 consecutive patients (28 eyes), 18 men and 10 women, with severe ocular rupture admitted to the Chinese PLA General Hospital between January 1999 and October 2002. The patient′s ages ragned from 16 to 58 years, mean 29 years. According to the internation standardized classification of ocular trauma, the injuries located in zone Ⅰ in 5 eyes, zone Ⅰ-Ⅱ in 8 eyes,zone Ⅱ in 3 eyes, zone Ⅱ-Ⅲ in 5 eyes, zone Ⅲ in 7 eyes, zone Ⅱ in 3 eyes, zone Ⅱ-Ⅲ in 5 eyes and zone Ⅲ in 7 eyes. The presenting visual acuity was in grade 4 (0. 02 to light perception) in 19 eyes, and grade 5 in 9 eyes. In 28 patients, 13 had the total absence of iris and lens, 10 had iris deletion more than 1/2, and 15 had lens opacity or rupture. Ultrasound biomicroscopy and B-scan revealed ciliochoroidal detachment in 17 eyes. The B-scan revealed vitreous hemorrhage and retinal detachment in all paitents. The intraocular pressure was from 5 to 11 mm Hg in all patients. The therappeutic operative procedures which were performed by one surgeon in all of the affected eyes included standard 3-port pars plana vitrectomy with scleral encircling buckle, endophotocoagulation and tamponading with silicone oil in all patients; lensectomy in 15 eyes; 360? retinotomy and retinectomy at anterior equator in 16 patients, and posterior equator in 12 eyes. Results During the operation, all patients were confirmed with vitreous hemorrhage and retinal detachment, including hemorrhagic ciliary body detachment in 9 eyes, suprachoroidal hemorrhage in 12 eyes, retinal twisting like morning glory in 11 eyes, and retinal incarceration in 17 eyes. Postoperative follow-up In 26 eyes who were followed up postoperatively from 6 months to 46 months, retinal reattachment was found in 20 patients (76. 9%) in whom the retina of 3 was reattached after revitrectomy and the silicone oil of 8 was removed at the fourth month after operation. In 20 eyes with reattached retina, 14 (70. 0%) had corrected visual acuity of 0. 02 or more, including 7 (35. 0%) had 0. 05 or more, 3 had 0. 1 or more, and 1 had the best visual acuity of 0. 3. Conclusion Retinectomy may improve the prognosis of severe ocular rupture and save the visual function of some patients.
