Insights
Concurrent strabismus surgery with glaucoma drainage device (GDD) placement in children effectively reduced horizontal deviation and controlled intraocular pressure (IOP). This combined approach is crucial for optimizing visual development and improving appearance in pediatric glaucoma patients.
Area of Science:
- Ophthalmology
- Pediatric Surgery
- Glaucoma Management
Background:
- Strabismus and glaucoma frequently coexist in pediatric patients.
- Surgical correction of strabismus concurrent with glaucoma drainage device (GDD) placement is a potential management strategy.
Purpose of the Study:
- To evaluate the outcomes of simultaneous strabismus surgery and GDD implantation in children.
- To assess the efficacy of combined surgery in managing horizontal deviation and intraocular pressure (IOP).
Main Methods:
- Retrospective review of pediatric patients undergoing lateral rectus (LR) muscle surgery and superotemporal GDD placement.
- Success defined by residual horizontal misalignment <10 prism diopters (PD), IOP <21 mmHg, no severe complications, and no further IOP-lowering surgeries.
Main Results:
- Fifteen eyes of 13 pediatric patients underwent combined surgery.
- Significant reduction in final IOP (12.4 ± 4.7 mmHg) and glaucoma medications.
- Strabismus success rate was 38% (5/13), and GDD success rate was 69% (9/13).
- Two patients required further strabismus surgery, and two required tube revision with endoscopic cyclophotocoagulation.
Conclusions:
- Concurrent strabismus surgery and GDD placement effectively decreases horizontal deviation and achieves IOP control in children.
- Addressing strabismus during GDD surgery is vital for maximizing visual development and cosmetic outcomes in pediatric glaucoma.
- This combined surgical approach offers a viable option for managing complex cases in pediatric ophthalmology.
Background:
Determine outcomes of concurrent strabismus surgery with placement of a glaucoma drainage device (GDD) in children.
Methods:
Retrospective review of pediatric patients who underwent simultaneous lateral rectus (LR) muscle surgery with superotemporal GDD placement. Strabismus and GDD success were defined as residual horizontal misalignment < 10 prism diopter (PD) and intraocular pressure (IOP) < 21 mmHg, no visually devastating complications, and no additional IOP-lowering surgeries.
Results:
Fifteen eyes of 13 patients (69% male) underwent LR surgery (14 recessions, 1 resection) for exotropia or esotropia simultaneous with GDD placement (13 Baerveldt, 2 Ahmed) at 8.34 ± 5.26 years. Preoperative visual acuity (VA) in operative eye (0.89 ± 0.54) was worse than non-operative eye (0.23 ± 0.44, p = 0.0032). Preoperative horizontal deviation was 38.3 ± 9.4 PD and LR recession was 7.4 ± 1.1 mm. At final follow-up, VA in operative eye (0.87 ± 0.52) was unchanged from preoperative (p = 0.4062). Final IOP was significantly decreased (12.4 ± 4.7 mmHg vs. 31.1 ± 11.4 mmHg, p = 0.0001) as was number of glaucoma medications (2.7 ± 1.7 vs. 1.1 ± 1.3, p = 0.0037). Five (38%) and 9 patients (69%) met criteria for strabismus and GDD success, respectively. Two eyes required tube revision and endoscopic cyclophotocoagulation and 2 eyes had additional strabismus surgery.
Conclusions:
Concurrent strabismus and GDD surgery decreased horizontal deviation and obtained IOP control. It is important to consider correction of strabismus at time of GDD placement to maximize visual development and improve cosmesis in children with glaucoma.
