From: Clinicopathological features of corneal invasion by filtering bleb
Preoperative and postoperative photos of a typical case (patient 1) From left to right are photos taken before the operation, and at 5 days, 2 months, and 1 year after the operation. The cornea is transparent, and the filtering bleb is good after the operation. However, large-scale iris defects and pupil deformation are present. At 2 months after the operation, the posterior boundary of the filtering bleb developed adhesions, and invaded into the corneal surface again. After loosening the posterior adhesion and applying local massage, the patient’s condition became stable. No significant progression has occurred during 1 year after the operation
