To identify risk factors related to the onset of secondary glaucoma in eyes that have undergone pars plana lensectomy for congenital cataract.
We investigated intraocular pressure levels after pars plana lensectomy for congenital cataract in 80 eyes of 44 patients who were followed up for at least 36 months. Mean age at the time of pars plana lensectomy was 11+/-18 months. Mean follow-up period was 116+/-57 months.
An elevation in intraocular pressure (>20 mmHg) was found in 21 eyes of 12 patients (26%). In 7 of these 21 eyes surgical treatment was required. The incidence of the coexistence of microcornea (or microphthalmos) with congenital cataract was significantly higher in the glaucoma group than that in nonglaucoma group. The final visual acuity in the nonglaucoma group was significantly better than that in the glaucoma group.
Our results show the importance of careful follow-up of intraocular pressure after pars plana lensectomy for congenital cataract, especially when microcornea (or microphthalmos) is present.
确定先天性白内障行晶状体平坦部切除术的患眼中与继发性青光眼发病相关的危险因素。
我们对44例患者的80只眼进行了先天性白内障晶状体平坦部切除术后的眼压水平调查，随访时间至少36个月。晶状体平坦部切除术时的平均年龄为11±18个月。平均随访期为116±57个月。
12例患者的21只眼（26%）眼压升高（>20 mmHg）。这21只眼中有7只需要手术治疗。青光眼组中先天性白内障合并小角膜（或小眼球）的发生率显著高于非青光眼组。非青光眼组的最终视力明显优于青光眼组。
我们的结果表明，先天性白内障晶状体平坦部切除术后仔细随访眼压很重要，尤其是存在小角膜（或小眼球）时。
