When treatment with medication or less invasive laser surgery does not lower intraocular pressure, your glaucoma specialist my need to perform a trabeculectomy. During a trabeculectomy, your Pacific Eye Institute Surgeon will create an alternate channel through which fluid inside the eye can exit. The eye pressure is reduced because fluid, which was once blocked, can now drain through the new opening into a reservoir (bleb) underneath the conjunctiva where it is then absorbed by the body. During the weeks following surgery, eye drops must be used to prevent inflammation and infection. Frequent follow-up visits are necessary, so that our team can follow your progress and determine if any further treatment is required.
