AIM:To evaluate the safety and efficacy of vitreous aspiration in continuous high-tension glaucoma cataract surgery. METHODS:Twenty-eight cases (28 eyes) with continu-ous high-tension glaucoma and cataract underwent vitreous aspiration first,and then triple-line glaucoma cataract surgery. RESULTS:Postoperative complications included shallow anterior chamber,malignant glaucoma,poorly controlled intraocular pressure,hyphema,iritis,vitreous hemorrh-age,posterior capsular opacity,etc.; after 1 week,and 6-12 months,respectively,the average IOPs were (17.20±5.11)mmHg and (14.57±7.33)mmHg,the difference compared with that of the preoperative was statistically significant (t=17.40,P<0.05;t=16.06,P<0.05); Visual acuity was improved two lines or more,1 line,0 line in 12,8,8 eyes and 12,10,6 eyes respectively,and compared with that of the preoperative,the difference was statistically significant (F=5.24,P<0.05;F=5.78,P<0.05). CONCLUSION:Vitreous aspiration in advance can quickly reduce the intraocular pressure,reconstruct anterior chamber,and is safe and effective for the treat-ment of continuous high-tension glaucoma cataract.
