case_images: 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).
case_images: VF, RNFL OCT images, and optic nerve photographs showing rapid deterioration 8 months after BKPro II implantation (February 2019). RNFL OCT: retinal nerve fiber layer optical coherence tomography.

case_images: 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.
case_images: Surgical incision using the initial tarsorrhaphy scar in a "U" shape with respect to the optical stem.

case_images: 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).
case_images: CPC being performed in the lower hemisphere.

case_images: 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.
