What is the posterior staphyloma?

Introduction. A staphyloma is a circumscribed outpouching of the wall of the globe. Posterior staphyloma is considered a hallmark of pathologic myopia and are among one of the major causes of developing maculopathy. However, it can be present in non-myopic eyes, often acquired secondarily due to infection or trauma.

What is a retinal staphyloma?

Answer: 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.

What causes posterior staphyloma?

Posterior staphyloma is a condition that can be present in highly myopic individuals with long axial lengths. It is caused by elongation of the globe due to thinning and bulging of the sclera and results in an irregular configuration of the retina at the posterior pole.

Does staphyloma cause blindness?

Macular degeneration can result in legal blindness among those with progressive myopia and posterior staphyloma. Programmed photoreceptor death, apoptosis, is operative in some.

What is uvea eye?

What is a tilted optic disc?

Tilted optic disks are a common finding in the general population. An expression of anomalous human development, the tilted disk appears rotated and tilted along its axes. Visual sequelae described with tilted optic disks include myopia, astigmatism, visual field loss, deficient color vision, and retinal abnormalities.

How do I check my eye fundus?

Hold the instrument with the hand ipsilateral to the examining eye; both are ipsilateral to the eye being examined: examine every left fundus with your left eye, holding the ophthalmoscope in your left hand (Figure 117.2); and every right fundus with your right eye and hand.
