Seidel test
Seidel Test
The Seidel Test (pronounced: /ˈsaɪdəl tɛst/) is a clinical examination used in ophthalmology to detect the presence of anterior chamber leakage, often indicative of a corneal perforation or a wound leak following ocular surgery.
Etymology
The Seidel Test is named after the German ophthalmologist, Ernst Fuchs, who first described the technique. The term "Seidel" is derived from the German word "Seide," meaning "silk," which refers to the delicate nature of the test.
Procedure
The Seidel Test involves the application of a fluorescein strip moistened with a non-preserved saline solution to the suspected area of leakage. The examiner then observes the area under a blue light. If a leak is present, the aqueous humor will dilute the fluorescein, causing a dark or negative stream within the green fluorescein-stained tears.
