Resolution of bilateral ptosis after reduction of unilaterally elevated intraocular pressure in a child with Axenfeld-Reiger spectrum disorder.

We report a 9-month-old boy with bilateral pseudoptosis associated with elevated IOP. The patient had previously undergone bilateral trabeculectomies and Ahmed tube placement and right cataract extraction and penetrating keratoplasty. At presentation, the right eye IOP was 24 mm Hg and the left eye IOP was 32 mm Hg. Approximately 2 weeks after dorzolamide was added to the treatment regimen for the left eye, the mother reported that the ptosis had resolved. We suggest several explanations for the resolution of the ptosis.
