Eventually, it got better. I used a handkerchief instead of Kleenex and it helped. I still use a hanky. Pigment is not normally shed inside the eye. In certain young, near-sighted patients it is, and it damages the drainage system of the eye with a resulting increase in eye pressure.
Pigmentary glaucoma is a secondary open-angle glaucoma.
I was six or seven. The pupil size may be different now, but could revert back to the same as the other eye. Shunt implants are extremely helpful in refractory types of glaucoma. We often use them. Refractory glaucomas are those cases that don't respond to medical and standard laser or surgical procedures.
