H40.63
Glaucoma secondary to drugs, bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
Bilateral secondary glaucoma due to drugs is a condition where increased pressure in both eyes results from the use of certain medications. This type of glaucoma can lead to optic nerve damage and vision loss if not properly managed. It is considered secondary because the elevated eye pressure is caused by external factors, specifically medication use, rather than primary eye diseases.
Causes & Symptoms
Clinical Causes: Use of corticosteroids (eye drops, oral or injectable) Certain medications with known ocular side effects, such as some antidepressants, antihistamines, or antipsychotics Prolonged use of medications that affect the eye's drainage system High-dose or long-term therapy with drugs that influence intraocular fluid dynamics
Key Symptoms: Gradual loss of peripheral vision Halo or rainbow-colored rings around lights Eye redness or discomfort Headache or eye pain, especially in advanced cases Nausea or vomiting in cases of sudden intraocular pressure spikes
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a comprehensive eye examination, including measuring intraocular pressure (tonometry), inspecting the optic nerve for damage, and assessing visual fields. A detailed medical history focusing on recent or ongoing medication use helps determine whether the glaucoma is drug-induced. Additional tests such as gonioscopy or OCT (optical coherence tomography) may be used to evaluate eye structures and optic nerve health.
Treatment Protocols: Adjusting or discontinuing the offending medication under medical supervision Medications to lower intraocular pressure, such as eye drops (beta-blockers, prostaglandin analogs, alpha-agonists), oral medications, or injections Laser therapy or surgical procedures if medications are insufficient to control pressure Regular monitoring of intraocular pressure and optic nerve health to prevent vision loss Addressing underlying health conditions that may contribute to medication use
