What does a positive Seidel test indicate?

A positive Seidel test is a crucial diagnostic tool in veterinary ophthalmology that specifically indicates the presence of a corneal perforation. This test involves the application of a fluorescein dye to the eye and observing whether the dye flows away from a suspected area of damage. If there is a perforation in the cornea, the aqueous humor from inside the eye will mix with the fluorescein dye and create a greenish stream, which can be observed as a positive result.

In the context of corneal issues, corneal perforation is a serious condition where there is a hole in the cornea, leading to potential complications such as intraocular infection or loss of the eye. It is critical to identify this condition promptly since the treatment often requires surgical intervention to repair the cornea and prevent further ocular damage.

Other options, while related to ocular health, do not directly correlate with the positive outcomes of the Seidel test. For instance, corneal scarring relates to damage that may not involve a perforation, while cataract formation and retinal detachment pertain to conditions affecting the internal structures of the eye rather than the integrity of the cornea itself. Thus, the specificity of the Seidel test to corneal perforation underscores the importance
