Insights
Surgical interventions for secondary glaucoma in pediatric uveitis significantly lower intraocular pressure (IOP). However, study quality is low, and complications are frequent, necessitating further research for optimal treatment strategies.
Area of Science:
- Ophthalmology
- Pediatric Surgery
- Glaucoma Research
Background:
- Pediatric uveitis can lead to secondary glaucoma, a serious condition requiring surgical management.
- Effective surgical interventions are crucial for preventing vision loss in affected children.
Purpose of the Study:
- To systematically review and compare surgical interventions for secondary glaucoma in pediatric uveitis.
- To assess outcomes such as intraocular pressure (IOP) and complications associated with these surgeries.
Main Methods:
- Systematic review adhering to PRISMA standards.
- Inclusion of studies with pediatric patients (≤16 years) undergoing glaucoma surgery for uveitis with ≥1 year follow-up.
- GRADE approach used to assess study quality; primary outcomes included IOP and medication use.
Main Results:
- Fourteen studies evaluated six different surgical procedures.
- All interventions significantly reduced IOP and the need for IOP-lowering medications.
- Cyclophotocoagulation showed the lowest success rates; common complications included ocular hypertension, hypotony, and hyphema, often requiring reoperation.
Conclusions:
- Surgical interventions play a vital role in preventing blindness by controlling medically uncontrolled IOP in pediatric glaucoma secondary to uveitis.
- Current evidence is of low to very low quality, precluding definitive preferences for any specific surgical method.
- Further research with larger sample sizes and direct comparative studies is essential to identify the most effective glaucoma treatments for this population.
Purpose:
To compare the outcomes and complications of different surgical interventions for secondary glaucoma in pediatric uveitis.
Methods:
Systematic review following the PRISMA standards. Main inclusion criteria were surgery for secondary glaucoma in pediatric uveitis at a mean age of 16 years or below, a mean follow-up period of at least 1 year after surgery, and at least 10 eyes per surgical intervention per study. We used the GRADE approach to assess study quality. Primary outcomes were intraocular pressure (IOP) and number of IOP lowering medications before and after surgery. Secondary outcomes were success rate and complications.
Results:
Fourteen studies fulfilled the inclusion criteria, in which one (n = 11) or more (n = 3) surgical interventions were described, comprising in total six different procedures. According to the GRADE criteria, the quality of the studies was low to very low, in particular because of the small size and the applied study designs. All surgical interventions provided a significant decrease in IOP and number of IOP lowering medications. The success rates during follow-up varied widely, with the lowest rates of success after cyclophotocoagulation. The most frequently reported complications were ocular hypertension, hypotony, and hyphema, with an indication for a reoperation in more than one-third of the cases. Permanent vision loss was infrequently seen and was attributed to prolonged hypotony.
Conclusions:
The described surgical interventions are able to prevent blindness by lowering a medically uncontrolled IOP to an acceptable level. Therefore, there is a crucial role for surgical intervention in these children. Based on the present studies, no preferences can be made. Given the reported complications, more research with larger sample sizes and direct comparisons is needed to determine the most successful glaucoma treatment in children with uveitis.
