H40.243
Residual stage of angle-closure glaucoma, bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
Residual stage of bilateral angle-closure glaucoma is a condition characterized by ongoing eye damage that persists even after initial treatment has been administered. It involves increased pressure within both eyes, which can affect vision over time. This condition falls under the ICD-10 code H40.243 and requires ongoing management to prevent further vision loss. Patients with this diagnosis often experience changes in vision and may require regular eye examinations to monitor the disease's progression.
Causes & Symptoms
Clinical Causes: Previous episodes of angle-closure glaucoma that have led to residual damage Incomplete or inadequate initial treatment of acute angle-closure glaucoma Structural changes in the eye, such as thickening of the iris or lens that obstruct fluid flow Formation of peripheral anterior synechiae (adhesions between iris and cornea) that persist after initial attack Progressive narrowing of the anterior chamber angle despite treatment interventions
Key Symptoms: Persistent blurred or decreased vision Halos around lights Eye pain or discomfort in some cases Redness and swelling in the eyes Sensitivity to light (photophobia) Reduced peripheral vision
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves comprehensive eye examinations, including assessing intraocular pressure using tonometry, gonioscopy to evaluate the angle of the anterior chamber, and optic nerve assessment. Imaging techniques such as optical coherence tomography (OCT) may be used to assess optic nerve health. The history of prior angle-closure episodes and the presence of residual structural changes also contribute to the diagnosis of residual stage glaucoma.
Treatment Protocols: Managing residual stage of bilateral angle-closure glaucoma focuses on controlling intraocular pressure and preventing further optic nerve damage. Treatment options may include: - **Medications:** Eye drops or systemic drugs to lower intraocular pressure. - **Laser procedures:** Such as laser iridotomy or laser trabeculoplasty to improve fluid drainage. - **Surgical interventions:** Trabeculectomy or other filtration surgeries to create new pathways for fluid outflow when medications are insufficient. - **Regular monitoring:** Ongoing eye examinations to track changes in intraocular pressure and optic nerve condition. Collaboration with an ophthalmologist is essential to tailor the treatment plan and ensure the best possible eye health management.
