Vision 20 Laser therapy: A painless laser is used to open the channels where the fluid comes out. This treatment is applied when the drops have not worked. If the drops and laser treatment don't work, you may need surgery. Angle closure glaucoma: Drops, pills, and medicine may be given through a vein (intravenously) to lower the pressure in your eye. Some people also need an emergency operation, called an iridotomy. 5f4a0465be26f.site123.me/
