Staphyloma is the term for a thinning of the outer, white coat of the eye (the sclera) in which the underlying pigmented tissue then adds its color to the thinned sclera, giving an appearance of bluish to almost black color. Request PDF on ResearchGate Proposed Classification of Posterior Staphylomas Based on Analyses of Eye Shape by ThreeDimensional Magnetic Resonance Imaging and WideField Fundus Imaging To Posterior staphyloma was known around 1800 and its association with myopia became evident some 30 years later.
There still seems to be no generally accepted classification of myopia and particularly not of degenerative or pathologic myopia. The emmetropic eye is spherical and symmetric in the images viewed from the inferior (B) and nasal (C) positions. D through F. 3D images of the eye with pathologic myopia and posterior staphyloma. Outpouching of the posterior segment, suggesting staphyloma is observed in the images viewed from inferior (D), nasal (E), and back positions.

However, the posterior segment and optic Congenital corneal staphyloma: clinical, Is there any reliable treatment for staphyloma? Answer: Staphylomas are abnormal outpouchings of the sclera (white of the eye) or cornea where the choroid or iris is visible due to thinning of the overlying tissue. Ten types of staphyloma were noted; five primary and five compound.
The primary staphyloma involved the posterior pole (Type I), macular area (Type II), peripapillary area (Type III), the fundus nasal to the disc (Type IV) and the area below the disc (Type V). The most predominant type was wide, macular staphyloma (74 of eyes with staphyloma), followed by narrow, macular staphyloma (14 of eyes with staphyloma).
In eyes with peripapillary and nasal staphylomas, the change of the curvature was slight and the eye had a nasally distorted shape.
