Insights
Transscleral contact cyclophotocoagulation with diode laser (TSCPC) is more effective than cyclocryocoagulation for lowering intraocular pressure in children. However, TSCPC is associated with more severe complications than cyclocryocoagulation.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
Background:
- Pediatric glaucoma management often requires interventions to control intraocular pressure (IOP).
- Cyclodestructive procedures are utilized when other treatments fail.
- Comparison of cyclocryocoagulation and transscleral contact cyclophotocoagulation (TSCPC) in pediatric populations is crucial for treatment selection.
Purpose of the Study:
- To compare the effectiveness and safety of cyclocryocoagulation versus diode laser transscleral contact cyclophotocoagulation (TSCPC) in pediatric patients.
- To evaluate intraocular pressure (IOP) reduction and complication rates for both procedures.
Main Methods:
- Sixty-nine eyes of 60 children (4 months to 16 years) underwent either cyclocryotherapy (40 eyes) or TSCPC (29 eyes).
- Patients included those aphakic post-cataract extraction, with aniridia, Sturge-Weber disease, or ROP complications.
- Intraocular pressure (IOP), visual acuity, and complications were assessed in early and late postoperative periods with a mean follow-up of 23 months.
Main Results:
- TSCPC required fewer procedures per eye (1.14) compared to cyclocryotherapy (1.3).
- IOP reduction was significantly greater with TSCPC (57.9% of eyes) than cyclocryotherapy (39% of eyes) (p=0.0003).
- Long-term IOP below 22 mmHg was achieved in 79% of eyes after TSCPC versus 60% after cyclocryotherapy; however, TSCPC had more severe complications including uveitis and transient hypotony.
Conclusions:
- Diode laser TSCPC demonstrates superior efficacy in lowering IOP in children compared to cyclocryocoagulation.
- While effective, TSCPC is associated with a higher incidence of more severe complications than cyclocryotherapy.
- Treatment choice requires careful consideration of efficacy versus potential adverse events in pediatric glaucoma management.
Purpose:
Comparison of the effectiveness and safety of cyclocryocoagulation and transscleral contact cyclophotocoagulation with diode laser (TSCPC) in children.
Patients And Method:
Sixty nine eyes of 60 children at the age from 4 months to 16 years were examined. Majority of patients was aphakic after congenital, traumatic and complicated cataract extraction. Aniridia, Sturge-Weber disease and ROP complications were observed. In 40 eyes cyclocryotherapy (I group), in 29 eyes TSCPC (II group) were performed. Intraocular pressure (IOP) was assessed in the early and late postoperative period. The number of procedures per one eye, IOP, visual acuity, and complications after cyclodestructive procedures were estimated. Follow-up ranged from 3 months to 4 years, mean 23 months.
Results:
Transscleral cyclocryocoagulations were performed once to 4 times in one eye with intervals from 1 month to 1 year, mean 1.3 procedures per eye. TSCPC was performed once in 29 eyes and twice in 4 cases, it was 1.14 procedures per eye. Before treatment IOP ranged from 21.3 to 50.6 mmHg, mean 29.18 mmHg in the I group and 24.4-54 mmHg mean 34.85 mmHg in the II group and in the early postoperative period were 10-25 mmHg, mean 17.7 and 2-26 mmHg, mean 14.65 mmHg relatively. Decreasing of IOP was observed in 39% of eyes after cryotherapy and 57.9% after TSCPC, p = 0.0003. In the long-term follow-up in IOP below 22 mmHg after cyclocryotherapy in 60% of eyes and after TSCPC in 79% was observed. Visual acuity ranged from no light perception to 0.5, mean 0.04. No changes of vision after cyclocryocoagulation were noted. After TSCPC transient visual function decreased from 0.2 to 0.04 in 1 eye but recovered after 2 weeks. After cyclocryotherapy only conjunctival oedema was observed in majority of cases. In the early postoperative period after TSCPC uveitis occured in 3 eyes (10.35%), transient hypotony in 2 eyes, hyphaema in one eye.
Conclusion:
Diode cyclophtocoagulation decreases IOP more effective than cyclocryocoagulation in children but complications after TSCPC are more severe than after cyclocryotherapy.
