Carbonic Anhydrase Inhibitor Drops
Topical eye drops that reduce aqueous humor production by inhibiting carbonic anhydrase in the ciliary body epithelium, lowering intraocular pressure effectively in pediatric glaucoma.
Additional treatment options
Visual Field and Optic Nerve Assessment
Periodic evaluation of optic nerve cupping progression and visual field testing appropriate for developmental age to track disease stability or progression over time.
monitoringGlaucoma Drainage Device Implantation
Implantation of a tube shunt device to provide an alternative drainage pathway for aqueous humor, typically reserved for cases failing conventional surgical approaches.
procedureNutritional Support for Ocular Development
