The Seidel test is performed to confirm which of the following findings in ocular trauma?

• A Presence of intraocular foreign body
• B Angle recession following blunt trauma
• C Posterior vitreous detachment
• D Full-thickness corneal or scleral wound with aqueous leakage ✓

Explanation

The Seidel test detects aqueous leakage through a full-thickness corneal or scleral wound. Fluorescein dye (concentrated, from a strip or 2% solution) is applied over the suspected wound and viewed under cobalt blue slit lamp illumination. A positive test shows streaming (dilution) of the dark orange-yellow fluorescein by the clear aqueous — appearing as a bright yellow-green rivulet flowing from the wound. A positive Seidel confirms an open globe or wound dehiscence requiring urgent surgical closure. It does not detect FBs, angle recession, or PVD.
