Overview
Other diagnostic studies associated with uveitis include slit lamp test and ocular tonometry. The slit lamp test is considered a gold standard modality in diagnosing uveitis. While intraocular pressure may increase or decrease depending on the anatomical location and severity of the inflammation, slit lamp test findings are relatively more consistent. Common slit lamp test findings include presence of inflammatory cells in the anterior chamber, keratic precipitates, and mutton fat precipitates. Slit lamp test findings associated with anatomical location include snowbanking in intermediate uveitis (e.g., pars planitis), snowballing in vitritis, and retinal edema in posterior uveitis.
Other Diagnostic Studies
Other diagnostic studies associated with uveitis include slit lamp test and ocular tonometry. The slit lamp test is considered a gold standard modality in diagnosing uveitis. Findings on these diagnostic studies include:
Slit Lamp Test
A slit lamp examination is the gold standard for confirming uveitis. It my be used in combination with fluorescin dye to detect abnormalities in the vasculature of the posterior uvea. The following findings may be found on slit lamp examination:[1][2]
- Inflammatory cells or flare in the anterior chamber
- Keratic precipitates in the anterior chamber
- Mutton fat precipitates in the anterior or intermediate segments of the uvea
- Inflammation of the posterior uvea and retinal edema
Ocular Tonometry
On ocular tonometry, findings associated with uveitis may include:[1][2]
- Decreased intraocular pressure (IOP) in acute anterior uveitis
- Increased intraocular pressure (IOP) in chronic anterior uveitis, intermediate, posterior, or panuveitis
