Etiology and associated conditions

There are many different types of uveitis that can be associated with secondary ocular hypertension or glaucoma. Some disorders may have a higher risk, such as Fuchs’ heterochromic iridocyclitis, Posner-Schlossman syndrome, and Grant’s syndrome. Generally, acute anterior uveitis presents with low intraocular pressure (IOP) due to ciliary body compromise leading to a reduction in aqueous production, but some patients with certain diseases may present with high IOP despite active intraocular inflammation. Inflammatory diseases limited to the anterior segment are not the only types that can cause secondary glaucoma; intermediate uveitis, posterior uveitis secondary to Toxoplasma retinochoroiditis, and panuveitis associated with Vogt-Koyanagi-Harada syndrome can also cause this problem [1].
