Aqueous humor is generally formed by the ciliary body, passes into the posterior chamber and then into the anterior chamber, leaving the eye at the angle where the cornea and iris meet. This glaucoma is diagnosed by means of tonometry with an instrument applied in external to the eye after administration of local anesthetic. To lower intraocular pressure administration of drugs or miotics may prove effective in controlling the condition. To tighten fibers in the ciliary body or to create a hole in the periphery of the iris, which allows aqueous humor to flow from the posterior to the anterior chamber and thus reduce intraocular pressure sometimes, this laser therapy is used. Hordeolum (stye): - This is a localized purulent, inflam
