Background

To evaluate the long-term efficacy and safety of the Paul Glaucoma Implant (Paul Glaucoma Implant) in a paediatric cohort.

Methods

A retrospective review of 113 eyes from 83 paediatric patients (age range 4 months to 18 years, mean 9 ± 5 years) who underwent Paul Glaucoma Implant implantation between June 2019 and April 2024.

n = 113 eyes

81.4%

Results

81.4%

at 5 years, most eyes still had pressure controlled, with or without eye drops

n = 113 eyes

More results

The mean preoperative IOP was 27.2 ± 6.2 mmHg.

The mean number of preoperative medications was 3.8 ± 0.8.

Postoperatively, they were 0.9 at 12, 18, and 24 months, 0.7 at 36 months, 1.0 at 48 months, and 0.7 at 60 months (p < 0.001).

More results

Thirty-nine eyes (35%) underwent Prolene stent removal (mean 9.7 months post-op), resulting in further IOP reduction (14.3 mmHg) and medication (0.8).

Conclusion

Paul Glaucoma Implant demonstrates sustained IOP reduction, reduced medication burden, and an acceptable safety profile in refractory paediatric glaucoma. It represents an effective long-term surgical option for this challenging cohort.
