Corneal perforation is an anomaly in the cornea resulting from damage to the corneal surface. A corneal perforation means that the cornea has been penetrated, thus leaving the cornea damaged.
Thecornea is a clear part of the eye which controls and focuses the entry of light into the eye. Damage to the cornea due to corneal perforation can cause decreased visual acuity.
Corneal perforation may cause difficulty in seeing and persistent eye pain.Physical examination may reveal discoloration of the cornea.
Perforation of the cornea may occur due to diseases of the cornea, injury during eye surgery, or infection of the eye, which may occur after surgery or procedures.Pellucid marginal degeneration may cause corneal thinning, leading to perforation.[1]
Corneal perforation can be diagnosed by using theSeidel 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.
The treatment of corneal perforation depends on the location, severity and the cause of damage
