STAPHYLOMA

Staphyloma refers to a localized bulging or protrusion of weak and thin outer tunic of eyeball that is cornea and sclera. It is generally black or whitish in color.

It can be classified into five types-

Anterior Staphyloma It results due to the ectasia of cornea and iris.

Intercalary Staphyloma It is the protrusion or a localized bulge in limbal area lined by root of iris. There may be associated secondary angle closure glaucoma which may cause progression of bulge if not treated and defective vision occurs.

Ciliary Staphyloma It occurs about 2-3mm away from the limbus, bulge of weak sclera lined by cilliary body. Common cause of thinning of sclera is scleritis and absolute glaucoma.

Equatorial Staphyloma It is due to bulge of sclera lined by the choroid in the equatorial region.

Posterior Staphyloma It refers to bulge of weak sclera lined by the choroid behind the equator.

 Management of staphyloma

The only management of staphyloma is evisceration along with PMMA implant was carried out under general anesthesia. Intraocular content removed using evisceration scoop leaving behind empty sclera pocket and PMMA ball implanted in the empty sclera pocket, sclera was sutured end to end followed by conjuctival suturing covering the scleral wound.
