Insights
Normalizing intraocular pressure (IOP) after trabeculectomy has minimal effect on eyeball growth and refraction in children with primary congenital glaucoma. Eye development is primarily age-dependent, even in buphthalmic eyes.
Area of Science:
- Ophthalmology
- Pediatric Glaucoma
- Surgical Outcomes
Context:
- Primary congenital glaucoma is a severe condition requiring early intervention.
- Trabeculectomy is a surgical procedure to reduce intraocular pressure (IOP).
- Understanding the long-term effects of IOP normalization on ocular development is crucial.
Purpose:
- To evaluate the influence of normalized intraocular pressure (IOP) after trabeculectomy on axial length and refraction in children with primary congenital glaucoma.
- To assess the relationship between postoperative IOP and ocular growth and refractive changes.
Summary:
- A study examined 36 eyes of 23 children with primary congenital glaucoma before and after trabeculectomy.
- Postoperative IOP was significantly lower (mean 16 mmHg) compared to pre-operative levels (mean 35.51 mmHg).
- No significant correlation was found between normalized IOP and changes in axial length or refraction in long-term follow-up.
Impact:
- Normalized IOP post-trabeculectomy has a limited impact on axial length and refraction in pediatric glaucoma.
- Ocular development, including in buphthalmic eyes, appears to be primarily driven by age.
- Findings suggest that factors beyond IOP control significantly influence ocular growth in these patients.
Purpose:
Evaluation of the influence of intraocular pressure (IOP) after trabeculectomy on the axial length and refraction of eyeballs in children with primary congenital glaucoma.
Material And 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.
