Scleral necrosis is the breakdown and death of scleral tissue, sometimes called scleral melt. It can appear as a localized, thinned area where the white of the eye becomes weak and fragile. The condition often starts near a site of injury or surgery, but immune-driven inflammation and infection can also trigger it. Because the sclera supports the globe, scleral necrosis can threaten eye integrity if it progresses.
read more about scleral necrosis ...Scleral necrosis can follow eye surgery, especially when the sclera has been stressed by cautery, radiation, or certain adjunct medicines used during procedures. A classic pattern is surgically induced necrotizing scleritis, where inflammation and tissue loss develop near a prior incision and can appear weeks to months later. Autoimmune disease can also drive scleral melt, particularly conditions linked with vasculitis or long-standing inflammatory arthritis. Infection is another cause, often after surgery or trauma, and it needs a different treatment plan than immune-driven disease. Sometimes more than one factor is involved, such as surgery plus an underlying autoimmune condition.
Symptoms depend on the cause and how fast the tissue breaks down. Many people notice increasing redness and deep eye pain, often worse with eye movement when active inflammation is present. Some notice a focal, pale or gray area on the sclera that looks thin, with a bluish hue from darker tissue underneath. Blurred vision can occur when nearby structures become inflamed or when complications develop. Sudden sharp pain, a new bulge, fluid leakage, or rapid vision drop needs urgent care because perforation can occur.
An eye doctor confirms scleral necrosis with a slit-lamp exam that looks for thinning, avascular areas, and exposed darker tissue beneath the sclera. The exam also checks the cornea and surrounding tissues because melt can extend beyond the original spot. Imaging such as ultrasound can help when deeper inflammation is suspected or the view is limited. The clinician also looks for clues that separate infection from autoimmune inflammation, since treatment differs. Blood work or referral for systemic evaluation is often part of the workup when an inflammatory disease is suspected.
Treatment starts by targeting the cause, since infection and autoimmune inflammation need different therapies. When immune-driven necrosis is present, systemic anti-inflammatory medicine is often used, and escalation to immunosuppressive therapy is considered when disease is severe or recurrent. When infection is suspected or confirmed, targeted antimicrobial therapy is used, sometimes along with surgical debridement, based on specialist assessment. Protective measures and close monitoring aim to prevent progression to perforation. If thinning becomes dangerous, surgical reinforcement such as a scleral patch graft or tissue coverage procedures can restore structural support.
They overlap, but the terms are not always used in the same way. Necrotizing scleritis refers to severe scleral inflammation that can cause tissue death and melting. Scleral necrosis describes the tissue damage itself, which can come from necrotizing scleritis, surgery-related causes, or infection. An eye exam helps clarify the mechanism. That distinction affects treatment choices.
Yes. Scleral melt has been reported after pterygium surgery, especially when adjunct measures such as mitomycin C or radiation were used. Excessive cautery and local ischemia can also raise risk. Symptoms can appear after the postoperative period rather than immediately. Any new focal thinning or severe pain after surgery needs prompt evaluation.
Yes. Progressive melt can thin the sclera until a full-thickness defect forms. This risk rises when inflammation stays active or infection is present. Early treatment aims to stop progression and protect the globe. Surgical reinforcement can be used when thinning becomes unsafe.
