Choroidal thickness alterations in idiopathic acute retinal vasculitis

Area of Science:

• Ophthalmology
• Retinal Imaging
• Vascular Diseases

Background:

• Idiopathic retinal vasculitis is an inflammatory condition affecting retinal blood vessels.
• Choroidal thickness changes may indicate active inflammation in the eye.

Purpose of the Study:

• To evaluate sub-foveal choroidal thickness (SFCT) in patients with acute idiopathic retinal vasculitis.
• Compare SFCT in affected eyes, unaffected fellow eyes, and healthy controls.

Main Methods:

• Prospective observational study involving 23 patients with idiopathic retinal vasculitis and 25 healthy subjects.
• Utilized spectral domain-optical coherence tomography with enhanced depth imaging for SFCT measurement.
• Included comprehensive ocular examinations and fundus imaging.

Main Results:

• Significantly increased SFCT in patients with retinal vasculitis compared to healthy controls (338.86 ± 28.72 µm vs. 296.72 ± 19.45 µm).
• In unilateral cases, the affected eye showed significantly increased SFCT compared to the unaffected fellow eye (333.5 ± 16.68 µm vs. 284.4 ± 15.68 µm).
• Anterior chamber inflammation was associated with lower best-corrected visual acuity but not significantly different SFCT.

Conclusions:

• SFCT increases during active inflammation in idiopathic retinal vasculitis.
• SFCT measurement via OCT with enhanced depth imaging is a valuable non-invasive tool for diagnosing and monitoring this condition.
