What are the different types of staphyloma?
Types of staphyloma according to location 1 Anterior, involving cornea and surrounding sclera 2 Intercalary, involving the limbus 3 Ciliary, involving the ciliary body, just behind the limbus 4 Equatorial, at the equator of the globe 5 Posterior staphyloma, at the posterior pole, behind the equator. The progression of posterior staphyloma may not stop at any specific age, unlike the moderate myopia cases which usually stabilize at around 18-21 years of age.
Why do myopic eyes have staphyloma?
Myopic eyes have increased elasticity due to its longer axial length, which causes it to expand and gradually thin to form these outpouchings. Secondary etiologies such as trauma or infection can disrupt the structure of the sclera, placing the injured region at risk for subsequent scleral thinning, to eventual development of staphyloma.
How many patients with myopia have staphyloma?
Up to 50% of patients with pathologic myopia are reported to have a staphyloma. The definition of pathologic myopia has been updated to include the presence of a posterior staphyloma. Though, it is important to note that not all patients with myopia develop a staphyloma. Staphylomas are associated with other macular complications related to myopia, ...

According to the location, staphyloma may be classified as. Posterior staphyloma, at the posterior pole, behind the equator. The progression of posterior staphyloma may not stop at any specific age, unlike the moderate myopia cases which usually stabilize at around 18-21 years of age.
How many types of staphyloma are there?
Staphylomas were first studied via direct observations of enucleated eyes or in vivo by B-mode echography by Curtin in 1977. He identified ten types of staphyloma, which are composed of five primary and five compound. Compound staphylomas are combinations of primary ones or complex variations of them, usually type I,
What are the complications of staphyloma?
Staphylomas are associated with other macular complications related to myopia, such as choroidal neovascularization, retinoschisis, and glaucomatous optic neuropathy. In the non-myopic eye, staphylomas can be seen as a response to trauma or infection, and rarely, surgery.
Why does staphyloma occur in the front of the eye?
Staphyloma occur in the front of the eye mostly as a response to trauma or infection in which the scleral architecture has been disturbed and the internal pressure of the eye stretches the weak point causing the protrusion and typical appearance.
Is a staphyloma congenital?
Posterior staphylomas are more commonly congenital (at birth) or as a manifestation of more extreme myopia (nearsightedness). The congenital staphylomas occur near the optic disc which is commonly of normal size, but frequently the vision is substantially lowered in these cases.
How to treat staphyloma?
It may include: Application of banked sclera to reinforce anterior staphylomas that appear threatening to erode into the eye. Laser treatment to resolve retinal detachment.
What are the different types of staphyloma?
Clinical types of Staphyloma: Depending upon the location of the protrusion on the eyeball, staphyloma can be of following types: Posterior staphyloma or staphyloma on back side of the eyeball that is typically diagnosed at the region of the macula. Anterior staphyloma or staphyloma in the front of the eye that involves the cornea and sclera.
Why does staphyloma protrude?
It occurs due to disturbed scleral architecture and stretching of eye leading to raised internal pressure from a weak point and eventually causing the protrusion and typical appearance of staphyloma. Causes:
Where is the intercalary staphyloma?
Intercalary staphyloma is a staphyloma that appears as a localised bulge in the limbal area of the eye. Ciliary staphyloma is a bulge of weak sclera that is lined by ciliary body and occurs about 2–3 mm away from the limbus. Equatorial staphyloma occurs on the equator of the eye.
What causes staphyloma?
They result from stretching, or “ectasia,” of the sclerouveal coats of the globe (Figure S107-1 ). The most common scenario of staphylomas is in a patient with severe axial myopia in which the sclera is thinned asymmetrically and the globe assumes an irregular shape.
What is the localization of a staphyloma?
Localizations of the staphyloma are various, including nasal, macula-centered, disc-centered, and tiered staphylomas. 1 Staphyloma underlying the macula is commonly associated with decreased vision,41 whereas in other locations in the posterior pole, central vision may not be affected. Rarely, a serous retinal detachment overlies the crest ...
What is a peripapillary staphyloma?
A peripapillary staphyloma is characterized by a staphylomatous excavation surrounding a relatively normal-appearing optic disc. The lesion is likely due to a failure of development of the posterior sclera from neural crest cells (Wise et al., 1966 ).
What is the incidence of anterior staphyloma?
Anterior staphylomas are common operative findings among patients with nontraumatic rhegmatogenous retinal detachment, with a reported incidence of 14%. Less commonly, they occur in eyes with increased intraocular pressure and recurrent necrotizing scleritis and after deep scleral resection for episcleral malignancies.
Is peripapillary staphyloma unilateral?
Clinical presentation. Peripapillary staphyloma is usually unilateral and not associated with other systemic or ocular abnormalities. Visual acuity is usually 20/200 or worse and associated with centrocecal scotomas.
Does staphyloma increase with age?
Posterior-pole staphyloma is present early in life and increases gradually with age.38 Its prevalence increases with axial length as well as with myopic refraction. 39 Chorioretinal atrophy and conus formation are correlated with the increasing staphyloma depth.
Is posterior staphyloma pathognomonic?
Posterior staphyloma is pathognomonic of degenerative myopia. Its frequence is clinically underestimated (10%) compared to histopathology (35%).25 A localized ectasia involves the sclera, the choroid, and the pigment epithelium.
What is P osterior staphyloma?
P osterior staphyloma, the posterior outpouching of the wall of the eye, is an important component of the diagnosis of pathologic myopia; indeed, it is one of the hallmarks of pathologic myopia. 1-5 With the exception of inferior staphyloma related to tilted disc syndrome, it does not occur in pathologies other than pathologic myopia. Thus, the presence of staphyloma is specific to pathologic myopia and critically important in differentiating simple school myopia with good best corrected visual acuity (BCVA) and pathologic myopia that could cause the loss of BCVA.
How did Curtin's classification of staphylomas work?
To overcome these issues with Curtin’s classification, the author 4 determined the type of staphylomas based on the shape of the entire eye using scans by 3D MRI. To simplify Curtin’s classification, the author analyzed only the contour of the outermost border of staphylomas. This resulted in Curtin types VI to X being placed into the type I category. The staphyloma type is renamed according to its location and distribution; this facilitates with memorization. ( Figure 7 ).
Can staphyloma occur in the posterior segment?
Posterior staphyloma can also develop in eyes without high axial myopia. The deformity of posterior segment characterized by staphyloma; it therefore, can independently occur from an elongation of the equatorial region. Staphyloma also can occur in eyes that do not have long axial length.
Is staphyloma a pathologic myopia?
Thus, the presence of staphyloma is specific to pathologic myopia and critically important in differentiating simple school myopia with good best corrected visual acuity (BCVA) and pathologic myopia that could cause the loss of BCVA. This review shows the current definition, clinical characteristics, and a classification based on ...
Can staphyloma be seen in 50° fundus?
However, most staphylomas involve wide areas of the fundus (especially the upper and temporal direction), and thus the entire extent of the staphyloma does not fit within the 50° field of view of conventional fundus photographs ( Figure 2 ).
Can staphyloma be seen in myopia?
Because staphylomas occur even in eyes without long axial length and the since staphyloma development significantly affects the outcome of myopic patients, pathologic myopia should be considered, by definition, by the presence of staphylomas and not by refractive error or axial length.
Disease Entity
- 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 second… - Types of staphyloma according to location
In staphyloma the wall of the globe (cornea or sclera) are ectatic/thin and bulging with uveal tissue in it giving it a pigmented color. Staphylus (Greek) means cluster of grapes and staphyloma gets its name from this. According to the location, staphyloma may be classified as 1. Anterior, i…
Diagnosis: Symptoms
- Staphylomas often present in highly myopic patients. Presenting symptoms of staphyomas include significantly worsening of vision in previously myopic patients. Severe staphylomas may also present in patients as an enlarged and protruding eye.
Management
- General Treatment
There is currently no gold standard treatment of staphyloma due to a generally unclear pathogenesis. One method of treatment is to monitor progression of the staphyloma. Many do not require treatment and remain stable over time. If there is observed thinning of the sclera, one tre… - Prognosis
Prognosis is good for patients with staphyloma, as progression is generally slow. Many do not need treatment and remain unchanged for years.
