Seidel sign
Seidel Sign
Seidel sign (pronunciation: /ˈsaɪdəl saɪn/) is a clinical sign in ophthalmology used to detect the presence of a leaking wound in the eye, particularly after trauma or surgery. It is named after the German ophthalmologist, Ernst Fuchs, who first described it.
Etymology
The term "Seidel sign" is derived from the name of the German ophthalmologist, Ernst Fuchs, who first described this clinical sign. The word "sign" in this context is used to denote a clinical indication or symptom of a particular medical condition.
Definition
Seidel sign is a clinical sign observed during a slit lamp examination of the eye. It is characterized by the streaming of aqueous humor from a wound in the eye, which appears as a dark stream against the green fluorescein dye used in the examination.
Clinical Significance
The presence of Seidel sign indicates a leaking wound in the eye, which could be due to trauma, surgery, or a spontaneous rupture of the globe. It is a serious condition that requires immediate medical attention to prevent further complications such as endophthalmitis, a severe inflammation of the interior of the eye, or glaucoma, a condition that damages the eye's optic nerve.
