H40.89
Other specified glaucoma
Clinical Classification Guidelines
Medical Intelligence & Overview
Other specified glaucoma is a category of eye conditions characterized by increased pressure within the eye, which can lead to damage of the optic nerve and possible vision loss. This classification includes various types of glaucoma that do not fit into the more common categories like primary open-angle or angle-closure glaucoma. Recognizing and understanding this condition is crucial for ensuring proper management and preserving eyesight. The condition is identified by the ICD-10 code H40.89, signifying a diagnosis that specifies a form of glaucoma not otherwise classified.
Causes & Symptoms
Clinical Causes: Secondary glaucoma due to trauma or injury to the eye Certain medications, such as corticosteroids, which can increase intraocular pressure Pigment dispersion syndrome, where pigment granules block the eye's drainage system Iridocorneal endothelial syndrome, affecting the iris and cornea Neovascular glaucoma, caused by abnormal blood vessel growth in the eye Uveitic glaucoma, associated with inflammation of the uveal tract Other ocular conditions that impair drainage or lead to increased intraocular pressure Unknown causes in some cases where the exact reason for increased pressure is not identified
Key Symptoms: Gradual loss of peripheral vision Blurred vision Eye redness or discomfort Headaches or eye pain in some cases Halos around lights Seeing a rainbow-colored halo around lights None in early stages; symptoms often appear once significant damage has occurred
Diagnostic & Treatment
Diagnosis Path: Diagnosis of other specified glaucoma involves comprehensive eye examinations, including intraocular pressure measurement, visual field testing, and detailed imaging of the eye’s drainage structures. An ophthalmologist may also use gonioscopy to examine the angle where the iris meets the cornea. Additional tests such as optical coherence tomography (OCT) can assess the optic nerve and retinal nerve fiber layer for signs of damage. Confirming a diagnosis requires differentiating this form of glaucoma from other types by considering clinical history, examination findings, and specialized testing.
Treatment Protocols: While specific management strategies depend on the individual case, common approaches include:
