What is the IOP for 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.
