The canal of Schlemm is a circular channel in the eye that drains aqueous humor from the anterior chamber into the bloodstream. If this channel is obstructed, the aqueous humor can't drain properly, causing an increase in intraocular pressure that can damage the optic nerve and lead to glaucoma.
Assessment data that supports the diagnosis of an obstruction of the canal of Schlemm affecting the left eye may include:
Increased intraocular pressure (IOP) in the left eye, as measured by tonometry.
Visual field loss in the left eye, which may be detected by a visual field test.
Blurred vision or decreased visual acuity in the left eye.
Enlargement of the left eye, known as buphthalmos, due to increased pressure inside the eye.
Redness or swelling in the left eye, which may be a sign of inflammation or infection.
Pain or discomfort in the left eye, which may be due to the increased pressure.
Cupping of the optic disc in the left eye, as seen on ophthalmoscopy.
It is important to note that these assessment data should be interpreted by a healthcare professional with expertise in eye disorders and should not be used to self-diagnose or treat any eye condition.
