Increased choroidal thickness may indicate systemic venous disease. Patients with higher choroidal thickness (CT) may be susceptible to lower extremity venous insufficiency (LEVI).
Area of Science:
- Ophthalmology
- Vascular Medicine
Background:
- Lower extremity venous insufficiency (LEVI) is a common condition.
- The relationship between systemic venous pathology and ocular findings is an area of ongoing research.
Purpose of the Study:
- To investigate the association between choroidal thickness (CT) and lower extremity venous insufficiency (LEVI).
Main Methods:
- A prospective cross-sectional study involving 56 patients with LEVI and 50 controls.
- Choroidal thickness was measured using optical coherence tomography.
- Venous reflux and saphenous vein diameter were assessed using color Doppler ultrasonography.
Main Results:
- Mean subfoveal choroidal thickness was significantly higher in the LEVI group compared to controls.
- Increased choroidal thickness was observed at multiple points in the LEVI group.
- While no direct correlation existed between CT and saphenous vein diameter, patients with CT > 400μm had wider veins.
Conclusions:
- Elevated choroidal thickness may be a sign of systemic venous pathology.
- Increased CT could be an indicator of susceptibility to LEVI.
- Further investigation for LEVI is recommended in patients presenting with high CT.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
