[8] [10] Dilated fundus exam is the preferred method of diagnosis, as undilated exam may be too limited to visualize lesions or neovascularization that are more peripheral. [11] Glaucoma: A group of eye diseases that can cause vision loss due to damage to the optic nerve, generally from increased intraocular pressure. Changes on ophthalmologic ...
When the test is performed in an eye with an afferent pupillary defect, light directed in the affected eye will cause only mild constriction of both pupils (due to decreased response to light from the afferent defect), while light in the unaffected eye will cause a normal constriction of both pupils (due to an intact efferent path, and an ...
The ICD-10-CM and ICD-10-PCS were developed by the Centers for Medicare and Medicaid Services (CMS) and the National Center for Health Statistics (NCHS). [ 48 ] [ 49 ] There are over 70,000 ICD-10-PCS procedure codes and over 69,000 ICD-10-CM diagnosis codes, compared to about 3,800 procedure codes and roughly 14,000 diagnosis codes found in ...
Symptoms include eye pain, eye redness, floaters and blurred vision, and ophthalmic examination may show dilated ciliary blood vessels and the presence of cells in the anterior chamber. Uveitis may arise spontaneously, have a genetic component, or be associated with an autoimmune disease or infection .

Eye examination with the aid of a slit lamp. Watzke-Allen test is done by projecting a thin line of light over the macula with a slit lamp. [4] A fundus lens or macular lens is used to aim beam of light on the macula. [5] It is best performed in a dilated eye, projecting a slit beam of approximately 100 μm.
