Secondary glaucoma is a disorder that occurs as a result of another eye or systemic illness, as opposed to primary glaucoma. Trauma, inflammation, pharmaceutical side effects, or underlying disorders hinder the eye's drainage system, resulting in increased intraocular pressure (IOP) and probable optic nerve injury. Causes & Types Secondary glaucoma can have a variety of causes. Eye injuries, infections, uveitis (eye inflammation), or complications from cataract or retinal surgery can cause it. Another prevalent reason is long-term steroid use, either topical or systemic.

Three types of secondary glaucoma exist: pigmentary glaucoma, neovascular glaucoma, and pseudoexfoliative glaucoma, each with a unique underlying disease. Symptoms and diagnoses Symptoms may include eye pain, redness, impaired vision, and halos around lights. However, secondary glaucoma might be asymptomatic in the early stages. Eye exams, including IOP measurement and visual field testing, are required for diagnosis. Treatment and Management aims to address the root cause and regulate IOP. Depending on the severity, treatment options include medicines, laser treatments, or surgery. Early detection and treatments are critical for avoiding irreparable vision loss. Regular eye examinations are essential for the best results, especially for those who are at higher risk.
