The Seidel test is used to assess the presence of aqueous humor leakage from anterior chamber of the eye. [1] Leakage may occur due to many corneal or scleral disorders, including corneal post-trauma, post-surgical leak, corneal perforation and corneal degeneration. [ 1 ]
A slit lamp exam allows a detailed inspection of the conjunctiva and sclera and improves the detection of globe injury. Slit lamp exam findings like decreased anterior chamber depth or damage to posterior chamber structures indicate open-globe injury. [3] A seidel test detects more subtle or partially self-sealing open-globe injuries.
Seidel's sign (also called Seidel's scotoma) is a sickle-shaped scotoma that is a superior or inferior extension of the blind spot. It occurs in some patients with ...
Corneal perforation can be diagnosed by using the Seidel test. Any aqueous leakage is revealed during the Seidel test confirms corneal perforation. A fluorescence strip is wiped over the wound. If the clear aqueous humor from the eye runs through the yellow stain, the patient tests positive for corneal perforation.
Hyphemas are frequently caused by injury, and may partially or completely block vision. The most common causes of hyphema are intraocular surgery, blunt trauma, and lacerating trauma. Hyphemas may also occur spontaneously, without any inciting trauma.
Treatment of closed globe trauma begins with the division of the eye into zones, each with unique anatomical structures and injury patterns: Zone I: the conjunctiva and corneal surface; the most common injuries seen in this zone are foreign debris retention by the conjunctiva or corneal epithelium/stroma, as well as corneal abrasions.
Enlargement of blind spot area in the visual field of the eye is the main sign and acute onset photopsia is the main symptom of AIBSE syndrome. [2] Other symptoms include monocular scotoma and reduced light perception.
Severe injury of the eye when the eye cannot be saved or attempts to save the eye have failed, such as after a globe rupture; In a deceased person, so the cornea can be used for a living person who needs a corneal transplant by a surgical operation called keratoplasty
