What Is Symblepharon?

Symblepharon is an abnormal adhesion between the eyelid's inner lining (palpebral conjunctiva) and the eyeball surface (bulbar conjunctiva). It forms after scarring from inflammation, infection, or injury to the conjunctiva. Mild cases can feel gritty or tight, while severe cases can limit eye movement and affect vision. Care focuses on protecting the eye surface and releasing adhesions when needed.

What Causes Symblepharon?

Symblepharon forms when the conjunctiva is damaged and then heals with scar tissue that bridges the lid to the eyeball. Chemical or thermal burns can trigger it because surface injury can be deep and widespread. Severe conjunctivitis, especially with membrane formation or ulceration, can also leave scars that stick surfaces together. Cicatrizing conditions such as Stevens-Johnson syndrome and ocular cicatricial pemphigoid can cause ongoing scarring that worsens over time. Eye surgery or trauma can also lead to adhesions when healing is complicated by surface inflammation.

What Are Symblepharon Symptoms And Complications?

A visible band of tissue connecting the eyelid to the eye is a common sign, along with tightness when blinking or looking around. Redness, burning, and foreign-body sensation can occur when the ocular surface stays irritated or dry. More advanced adhesions can restrict eye movement and reduce how wide the eyelid opens, which can feel like stiffness in certain gaze directions. If scarring disrupts tear spread across the cornea, blurred vision and light sensitivity can increase. Severe cases can distort the conjunctival fornix and complicate contact lens wear or future eye procedures.

How Is Symblepharon Diagnosed?

Diagnosis starts with a slit-lamp exam to look for adhesions in the fornix and along the lid margin. The cornea is checked for staining, dryness, or scarring that signals surface compromise. Medical history matters, since prior chemical exposure, severe infections, autoimmune scarring disorders, or trauma can point to the cause. When a chronic cicatrizing disease is suspected, a specialist might suggest more workup, which can include lab testing or biopsy in select cases. Photos and measurements can document severity and help track progression over follow-up visits.

How Is Symblepharon Treated?

Early care focuses on calming inflammation and protecting the ocular surface with frequent lubrication and targeted medical therapy. In fresh injuries, devices such as symblepharon rings can help keep the conjunctival fornix open while healing occurs. When adhesions restrict movement or threaten the cornea, surgical lysis can separate the tissues. Surgeons often cover raw areas with graft material, such as amniotic membrane or mucous membrane, to reduce scarring during healing. Long-term follow-up is often needed when a scarring disorder is driving the problem.

Frequently Asked Questions About Symblepharon

Can Symblepharon Affect Vision?

Yes. Vision can drop when scarring pulls on the cornea, disrupts the tear film, or blocks a clear line of sight. Risk rises when adhesions are extensive or when a scarring disease is active. An eye exam can show whether corneal damage is driving blur.

Does Symblepharon Always Need Surgery?

No. Mild adhesions without corneal risk can be managed with surface protection and control of inflammation. Surgery is considered when movement is limited, discomfort stays high, or the cornea is at risk. A specialist can match the plan to severity and cause.

Can Symblepharon Come Back After Treatment?

It can. Recurrence is more likely when the underlying condition keeps causing scarring. Ongoing control of inflammation plus surface protection can lower the chance of repeat adhesions. Regular visits help catch early changes.
