The incidence of glaucoma following paediatric cataract surgery: a 20-year retrospective study.
OBJECTIVE
To analyse the incidence of glaucoma in children undergoing cataract surgery and determine whether early surgery is associated with increased risk of glaucoma.


METHODS
A retrospective chart review of all children aged 14 years or less who had surgery for congenital or developmental cataract at one unit over the last 20 years. The children were divided into three groups; group 1 consisting of children aged < or =50 days at surgery, group 2 those aged 51 days to 1 year, and group 3 aged 1-14 years.


RESULTS
We identified a total of 104 eyes of 74 children. The medical records for 100 eyes (71 children) were available for review. In all, 17 eyes (12 children) were aged < or =50 days at surgery, none of which have developed glaucoma. Group 2 consisted of 28 eyes (17 children) with one patient developing glaucoma in both eyes 11 years after surgery. Group 3 consisted of 55 eyes (42 children), none of which have developed glaucoma. After a median follow-up period of 4.9 years (range 0.6-19.6 years, mean 6.4 +/- 5.2 years) 2% of eyes had developed glaucoma. There was no significant difference in the length of follow-up between groups (H=2.979, P=0.22, Kruskal-Wallis Test).


CONCLUSIONS
There was a low incidence of glaucoma in our series and this was not increased in those having surgery in the first 6 weeks of life. Our findings contribute further evidence for the variability in prevalence of glaucoma after paediatric cataract extraction in the literature and suggest that factors other than age at surgery are important risk factors for this condition.
