The benefit of scratch patch testing to demonstrate ocular contact allergy to brimonidine tartrate.

Introduction: Ocular allergies to brimonidine are frequent in patients treated for glaucoma. There is variability in reporting due to the lack of diagnostic criteria and the absence of cutaneous testing. Many false-negative patch tests (PT) have been described.

Transconjunctival suturing of the scleral flap for overfiltration with hypotony maculopathy after trabeculectomy.

Objective: To assess the efficacy of transconjunctival suturing of the scleral flap in improving hypotony maculopathy resulting from overfiltration after trabeculectomy.

Design: Retrospective review.

Participants: 35 eyes of 33 patients.
