Staphyloma refers to a localised bulging of weak and thin outer tunic of the eyeball (cornea or sclera),
lined by uveal tissue which shines through the thinned out fibrous coat.
Ciliary staphyloma is characterized by a bulge or protrusion of the weak scleral tissue, which is lined by the ciliary body. This condition typically occurs approximately 2 to 3 millimeters away from the limbus, which is the border between the cornea and the sclera. Scleral staphyloma can vary in size and appearance, but its common thread is the abnormal protrusion of the scleral tissue.

Causes of Scleral Ciliary Staphyloma
Several factors can contribute to the development of scleral staphyloma:
- Thinning of Sclera following Perforating Injury: One of the primary causes of scleral staphyloma is a perforating injury to the eye. When the eye experiences a penetrating wound or trauma, it can lead to a localized thinning of the sclera. Over time, this weakened area can bulge and result in the formation of a staphyloma.
- Scleritis: Scleritis is a painful inflammatory condition affecting the sclera. Chronic or severe scleritis can lead to scleral thinning and staphyloma formation in some cases.
- Absolute Glaucoma: Absolute glaucoma is a rare and severe form of glaucoma in which intraocular pressure becomes dangerously high. The increased pressure within the eye can lead to thinning of the sclera and potentially the development of scleral staphyloma.

Implications of Scleral Ciliary Staphyloma
Scleral staphyloma can have significant implications for the affected individual’s vision and overall eye health. Some of the potential consequences include:
- Visual Disturbances: Depending on the location and size of the staphyloma, it may lead to visual disturbances, such as blurred or distorted vision. These visual impairments can impact daily activities and reduce the quality of life.
- Increased Risk of Eye Infections: The weakened scleral tissue associated with staphyloma may be more susceptible to infections, which can further compromise eye health.
Ciliary Staphyloma treatment
Treatment for scleral staphyloma can indeed involve surgical procedures like scleral patch graft or partial scleral resection (PSR), depending on the size and severity of the staphyloma. These surgical interventions aim to reinforce the weakened scleral tissue and improve the structural integrity of the eye. Let’s take a closer look at each of these treatment options:
- Scleral Patch Graft: This surgical procedure involves the placement of a donor scleral patch over the area of the staphyloma. The donor sclera is typically obtained from an eye bank and is carefully sutured onto the weakened scleral tissue. The patch graft provides additional support to the thinning or bulging area, helping to prevent further progression of the staphyloma. Scleral patch grafts are often considered for larger or more severe staphylomas.
- Partial Scleral Resection (PSR): PSR is a surgical technique where a portion of the thin or weakened sclera is removed, and the edges are sutured back together. This procedure is usually performed for smaller staphylomas or in cases where localized scleral thinning needs to be addressed. By removing the weakened area and suturing the remaining tissue, the eye’s structural integrity can be improved.
The choice between scleral patch graft and PSR depends on various factors, including the size and location of the staphyloma, the patient’s overall eye health, and the surgeon’s expertise. It’s essential for individuals with scleral staphyloma to consult with an experienced eye specialist or ophthalmologist who can evaluate their specific condition and recommend the most suitable treatment approach.
Both surgical techniques aim to strengthen the sclera and reduce the risk of complications associated with staphyloma, such as visual disturbances, infection, or rupture. Successful treatment can help improve the patient’s vision and preserve the health of the affected eye. As with any surgical procedure, there are risks and potential complications, so patients should discuss these with their healthcare provider and weigh the benefits against the risks before proceeding with treatment.
