title: [Clinical analysis of aphakic glaucoma following infantile congenital cataract surgery].
abstract: OBJECTIVE
  To investigate the incidence, occurrence time and types of aphakic glaucoma following infantile congenital cataract surgery.
  
  
  METHODS
  The records of children who underwent surgery for congenital cataract within the first 24 months of life between January 2010 and January 2014 at the First Affiliated Hospital of Zhengzhou University were retrospectively reviewed.Children with preoperative conditions associated with glaucoma were excluded.The following parameters were ascertained: age received cataract surgery, operation method, the incidence, occurrence time and types of glaucoma.
  
  
  RESULTS
  A total of 205 patients (324 eyes) with an average surgery age of 13.9 months were included, and the mean follow-up time was 47.6 months.The operation method was cataract extraction combined with posterior continuous circular capsulorhexis and anterior vitrectomy.Twenty-nine patients (37 eyes, 11.42%) had subsequent development of aphakic glaucoma, 9 eyes of which (2.78%) developed early onset angle closed glaucoma, and the occurrence time was (4.2±2.6) months after cataract surgery; 28 eyes (8.64%) developed late onset open angle glaucoma, 26 of which was angle open glaucoma, and the rest two was angle closed glaucoma.The occurrence time was (37.5±11.0) months after cataract surgery. Twenty-nine patients (37 eyes) developed aphakic glaucoma had cataract surgery within 2 to 12 months (6.8 months on average). The rest 176 patients (287 eyes) who did not develop glaucoma had cataract surgery at 10 to 24 months (14.1 months on average).
  
  
  CONCLUSIONS
  The incidence of aphakic glaucoma following infantile congenital cataract surgery is 11.42%.Aphakic glaucoma is divided into two types of early onset angle closed glaucoma and late onset open angle glaucoma.The occurence time of glaucoma was 2 months to 64 months after cataract surgery.Late onset open angle glaucoma is the most common type.
