Failure of Goniosurgery for Glaucoma Associated With Sturge-Weber Syndrome.

PURPOSE: To report the surgical results of goniosurgery for children with glaucoma associated with Sturge-Weber syndrome.

METHODS

Retrospective review of medical records of patients who had initial goniosurgery for glaucoma associated with Sturge-Weber syndrome.

RESULTS

A total of 46 eyes of 42 patients who had glaucoma associated with Sturge-Weber syndrome and were treated with initial goniosurgery were identified to determine the efficacy of therapeutic goniotomy and trabeculotomy (goniosurgery). The average age at the time of goniosurgery was 1.5 years (range: 1 month to 23 years). Office intraocular pressure (IOP) measurements before goniosurgery were recorded in 76% of patients (32 of 42 patients) with an average measurement of 35 mm Hg (range: 25 to 50 mm Hg). The average interval to failure was 4 months (range: 1 to 48 months). Forty-six eyes underwent goniosurgery with a rate of failure of 98% (45 of 46 eyes) and a qualified success rate of 2% (1 of 46 eyes). Fifty-one goniotomy and 11 trabeculotomy procedures were performed. On gonioscopy, the filtration angles were all abnormal with variable width and visibility of the ciliary body band and less visible scleral spur. The trabecular meshwork was seen preoperatively in 100% of eyes (41 of 41 eyes) examined, all of which underwent goniosurgery. Five eyes underwent goniosurgery without documented gonioscopy. The ciliary body band was seen in 39% of eyes (16 of 41 eyes) and the scleral spur was visible in 10% of eyes (4 of 41 eyes).

CONCLUSIONS

Goniosurgery is not an effective initial glaucoma surgery for glaucoma associated with Sturge-Weber syndrome. It can be used to temporize the IOP, but ultimately other forms of glaucoma surgery must be considered when indicated. [J Pediatr Ophthalmol Strabismus. 2020;57(6):384-387.].
