Risk factor analysis of aphakic glaucoma following infant cataract surgery

Abstract

Objective To study and analyze the rules and characteristics of the development of aphakic glaucoma (AG) following infant cataract surgery.Methods A retrospective study of 228 cases (395 eyes)who received cataract surgery in Shengjing Hospital from September,2001 to September,2009.AG was defined as a repeated ocular hypertension (＞25mmHg) over 2 weeks after cataract surgery.The postoperative follow-up was x± s (56± 13) mo.Sixty-three eyes (15.9%) had the presence of AG.Results The OR value of ＜3mo group was 13.429 (P =0.001),3-6 mo group was 6.889 (P=0.008).The patients with nuclear cataract had the highest risk of AG (OR=3.759,P=0.004) among other cataract types.Cataract infants with other ocular abnormalities also had an extremely high risk of AG compared with simple cataract (OR=21.382,P =0.000).Conclusions Cataract surgery in earlier infancy,nuclear cataract and cataract with other ocular abnormalities are likely the risk factors of AG after infant cataract surgery.
