Practice Patterns in the Management of Primary Pterygium: A Survey Study.

PURPOSE

To characterize cornea specialists' current practice preferences in the management of primary pterygium.

METHODS

A 25-item survey regarding indications for surgery, surgical technique, use of adjuvant therapy, type and duration of postoperative therapy, and treatment of early recurrences was designed and sent to members of the Cornea Society through the kera-net listserv.

RESULTS

In total, 199 cornea specialists completed the questionnaire. More than 90% considered that surgery should be performed when there is proximity of the pterygium to the visual axis, pain or redness, eye movement restriction, or induction of astigmatism. Cosmesis was considered as an indication by 41.7% of the participants. The most frequent technique for pterygium excision was complete resection including the base and a moderate quantity of Tenon capsule followed by autologous conjunctival or limbal-conjunctival graft. The preferred graft fixation method in this survey was fibrin glue (61.2%). Most respondents reported a recurrence rate of less than 5% and no use of adjuvant agents to prevent recurrence. When early recurrence did occur, the preferred agents were corticosteroids.

CONCLUSIONS

This study reflects the preferences of cornea experts regarding primary pterygium treatment and may serve as a guide for the management of this pathology.
