During the follow-up, systematic optic nerve photographs were taken, and visual field (VF) tests and retinal nerve-fiber layer optical coherence tomography were performed (shown in Fig. 1).

Two months after these early signs, the VF confirmed a rapid deterioration (shown in Fig. 2), and hence, the patient was put on oral acetazolamide 125 mg tid and brimonidine plus timolol tid and scheduled for CPC.

The complete tarsorrhaphy was opened carefully with an electrosurgical scalpel, and the incision was made using the initial tarsorrhaphy scar and in a "U" shape with respect to the optical stem (shown in Fig. 3).

TSCPC was performed in the lower hemisphere (180 ) with an Iris Medical OcuLight SLx laser system (Iridex, Mountain View, CA, USA) (shown in Fig. 4), applying 15 shots with the exposure duration set at 2 s and the power at 2,200 mW.
