[Eye growth in children with primary congenital glaucoma after trabeculectomy].
OBJECTIVE
Evaluation of the influence of intraocular pressure (IOP) after trabeculectomy on the axial length and refraction of eyeballs in children with primary congenital glaucoma.


METHODS
Thirty six eyes of 23 children at the age from 7 days to 6.5 years (mean 17.1 months), were examined. Measurements of corneal diameter, axial length, IOP and refraction were done before trabeculectomy and in the long-term follow-up (mean 7.9 years) after surgery.


RESULTS
Horizontal corneal diameter didn't change and ranged from 10 to 15 mm, mean 13.22 mm. Mean value of axial length before trabeculectomy was 22.45 mm and 23.27 mm at last visit. The difference was statistically significant. The axis decreased in 3 eyes, was the same in 3 eyes. In the others the eye growth changed proportionally to the age of child. IOP values were statistically lower after surgery (mean 16 mmHg) than before treatment (mean 35.51 mmHg). There was no correlation between IOP and axial length of eyeballs (p = 0.69) and between IOP and refraction changes (p = 0.42) in the long-term follow-up.


CONCLUSIONS
There is small influence of normalised IOP after trabeculectomy on size of eyeballs and refraction in children with primary congenital glaucoma. The development of eyeballs even buphthalmic is proportionally to the age.
