Glaucoma Management in Sturge-Weber Syndrome Using the Delphi Process.

OBJECTIVE

We sought to identify areas of consensus and nonconsensus in the ophthalmic screening, diagnosis, and management of Sturge-Weber syndrome (SWS).

DESIGN

Modified Delphi methodology.

PARTICIPANTS

North American glaucoma experts with prior experience managing glaucoma in patients with Sturge-Weber syndrome.

METHODS

A modified Delphi process was used as a systematic and structured communication technique, consisting of 2 rounds of electronic questionnaires to a wider group, followed by an in-person meeting of selected experts. Questions that did not reach agreement were reformulated in each round, with the aim of reaching consensus. The University of Rochester Research Subject Review Board noted that this study was exempt from IRB approval. This study adhered to the Declaration of Helsinki.

MAIN OUTCOME MEASURES

Consensus was defined as agreement among at least 85% of participants for the electronic questionnaires or a minimum of 70% during the in-person meeting.

RESULTS

Among other recommendations, the panel concluded that all patients with a facial port wine birthmark should be assessed for glaucoma within a month of birth, with shorter screening intervals thereafter in patients with bilateral eyelid involvement, choroidal hemangioma, and signs of elevated episcleral venous pressure. There was no consensus on timing of follow-up visits. In children aged ≥4 years with signs of glaucoma, medical intervention is the initial consideration. In children aged <4 years, the primary intervention is likely to be surgical, with some form of goniosurgery as the first-choice procedure.

CONCLUSIONS

Consensus for screening, diagnosis, and management in patients with SWS is designed to hopefully improve clinical practice and patient outcomes. Questions where consensus was not reached may highlight variations in practice, conflicting evidence, or areas that might benefit from further research and investigation.
