What is the IOP in glaucoma?
The indication for intraocular pressure (IOP)-lowering medications in childhood glaucoma can vary with the context of diagnosis and disease course. When primary surgical intervention is advantageous (e.g., in primary congenital glaucoma, in which angle surgery has a high likelihood of success) or urgently necessary (e.g., angle-closure glaucoma, in which intervention can open the angle and allow it to regain function), medical therapy is adjunctive. In these cases, medications (topical and sometimes systemic) are used as a temporizing measure and often to help clear corneal edema ahead of surgery. Medications can also be used postoperatively if surgery has incompletely controlled the IOP.
How does carbonic anhydrase inhibitor work?
Carbonic anhydrase inhibitors (CAIs) work by reducing aqueous production; both oral and topical formulations are available and have been widely used in children with glaucoma. The topical CAIs are generally second-line medication for children, but might be preferred in small infants and in those with contraindications to beta blockers, alpha agonists, and prostaglandin analogs. CAIs lack the convenience of once-daily drugs, but add well to all other drug classes.

Except for brinzolamide, all CAI s are available in generic form.

Is timolol a preservative?
Timolol is also available in a preservative-free formulation. Systemic side effects of beta blockers can be minimized by closing the eyes following application or using a technique called punctal occlusion that prevents the drug from entering the tear drainage duct and systemic circulation.

What is acute angle closure?
Acute angle closure is an urgent but uncommon dramatic symptomatic event with blurring of vision, painful red eye, headache, nausea, and vomiting. Diagnosis is made by noting high intraocular pressure (IOP), corneal edema, shallow anterior chamber, and a closed angle on gonioscopy. Medical or surgical therapy is directed at widening the angle and preventing further angle closure. If glaucoma has developed, it is treated with therapies to lower IOP.
What is an ACG?
Angle-closure glaucoma (ACG) is a group of diseases in which there is reversible (appositional) or adhesional (synechial) closure of the anterior-chamber angle. The angle closure may occur in an acute or chronic form.

Gonioscopy is also important for the detection of plateau iris and other specific anatomic configurations. Gonioscopy may be therapeutic in breaking the attack of acute angle closure. Result: TM is not visible in angle closure because the peripheral iris is in contact with it.
