RESUMO
AIM: To observe the comparison of vitrectomy combined drug therapy ( Ranibizumab injection ) and single vitrectomy for proliferatived diabetic retinopathy ( PDR ) and the influence of the curative effect and prognosis of patients. METHODS:In this study, 112 cases (125 eyes) with PDR were selected and randomly divided into experimental group and control group ( n= 56 ) . Fifty-six cases ( 61 eyes ) in experimental group were injected by drug therapy of 0. 5mg ranibizumab and received vitrectomy;In control group, 56 cases ( 64 eyes ) were received single vitrectomy. The intraoperative and postoperative differences of clinical indicators were analyzed in two groups. RESULTS: The average operation time, intraoperative electric coagulation hemostasis rate and iatrogenic hiatal incidence of the experimental group were lower than that of the control group:(95. 00±13. 00) min vs (133. 00±14.5) min, 11% vs 34%, 5% vs 20%, respectively (PCONCLUSION: Patients with PDR injected with ranibizumab in vitreous cavity before vitrectomy can effectively reduce the operation time, less intraoperative blood loss, the incidence of iatrogenic hiatus, and intraoperative and postoperative complications. The postoperative visual acuity was better than before.
RESUMO
? AlM: To analyze the incidence, characteristics and related risk factors of high intraocular pressure after pars plana vitrectomy ( PPV) . ?METHODS: Totally, 146 patients (146 eyes) undergone PPV in our hospital were selected. Age, gender, eye, course and operation time of patients were compared, in order to understand the incidence rate and characteristics of high intraocular pressure. Primary diseases, intraoperative treatment methods and intraocular tamponade type were compare, in order to analyze the related risk factors of high intraocular pressure. ? RESULTS: Forty - seven patients occurred high intraocular pressure after operation, the incidence rate was 32. 2%. There was no significant difference in age, gender, eye, course and operation time (P>0. 05). The incidence rate in diabetic patients with simple vitreous hemorrhage and with tractional retinal detachment were 21.1% and 57.6%, respectively (P 0. 05 ). The incidence rate of using silicone oil, C3 F8 and simple ventilation were 59. 7%, 34. 5% and 14. 5%, respectively (P ? CONCLUSlON: After vitrectomy intraocular hypertension incidence and preoperative, intraoperative treatment of primary disease is closely related to factors such as the way and intraocular tamponade.
RESUMO
AlM: To observe the clinic effect of oral mucosa transplantation in the treatment of severe contracted conjunctival sac after ocular prosthesis implantation . METHODS: Thirty-three cases ( 33 eyes ) with globe disorders and severe contracted conjunctval sac were operated ocular prosthesis implantation firstly, and conjunctival sac plasty using oral mucosa after 6mo. RESULTS: Thirty - one cases were successful, no complications appeared. One case had primary ptosis and 1 case had recurrent conjunctival sac contracture. CONCLUSlON:lt is recognised that the methods of oral mucosa transplantation in severe contracted conjunctival sac after ocular prosthesis implantation are effective on those cases.
