Causes & Risk Factors
Several factors can contribute to Infectious Scleritis.
Infectious scleritis develops when harmful microorganisms breach the eye's natural defenses and establish an infection in the sclera.
Infectious scleritis develops when harmful microorganisms breach the eye's natural defenses and establish an infection in the sclera. Bacteria are the most common culprits, with Pseudomonas aeruginosa and Staphylococcus epidermidis being frequent offenders. These bacteria can enter through surgical incisions, penetrating injuries, or spread from nearby infected tissues. Fungal infections, though less common, can occur and are often more challenging to treat than bacterial infections.
The eye's sclera normally resists infection due to its dense, fibrous structure and limited blood supply.
The eye's sclera normally resists infection due to its dense, fibrous structure and limited blood supply. However, certain circumstances can compromise these natural defenses. Recent eye surgery creates potential entry points for bacteria, particularly procedures involving scleral tissue or those requiring sutures. Even minor surgical complications or poor wound healing can provide opportunities for microorganisms to establish themselves.
Trauma to the eye, especially injuries involving foreign objects or contaminated materials, can introduce infectious agents directly into the scleral tissue.
Trauma to the eye, especially injuries involving foreign objects or contaminated materials, can introduce infectious agents directly into the scleral tissue. Additionally, infections can spread from adjacent structures, such as severe conjunctivitis or corneal infections that penetrate deeper into the eye. In some cases, bloodstream infections can seed the eye, though this route is less common. People with compromised immune systems face higher risks as their bodies are less capable of fighting off invading microorganisms.
Risk Factors
- Recent eye surgery, especially scleral procedures
- Penetrating eye injuries or trauma
- Previous episodes of scleritis
- Autoimmune diseases like rheumatoid arthritis
- Diabetes mellitus
- Immunosuppressive medications or treatments
- Chronic steroid use
- History of eye infections
- Poor wound healing after eye surgery
- Contact lens wear with poor hygiene
- Advanced age over 60 years
Diagnosis
How healthcare professionals diagnose Infectious Scleritis:
- 1
Diagnosing infectious scleritis requires a comprehensive eye examination combined with laboratory testing to identify the specific infectious organism.
Diagnosing infectious scleritis requires a comprehensive eye examination combined with laboratory testing to identify the specific infectious organism. Eye doctors typically begin with a detailed medical history, focusing on recent surgeries, injuries, or symptoms that might suggest infection. The physical examination includes careful inspection of the eye's external appearance, checking for characteristic signs like deep redness, swelling, and areas of thinning in the sclera.

Specialized imaging tests help assess the extent of the infection and any potential complications.
Specialized imaging tests help assess the extent of the infection and any potential complications. Ultrasound of the eye can reveal fluid collections or abscesses within the eye tissues. CT scans may be necessary if doctors suspect the infection has spread beyond the eye itself. Optical coherence tomography provides detailed images of the eye's internal structures, helping to evaluate damage and monitor treatment progress.

Laboratory testing plays a crucial role in confirming the diagnosis and guiding treatment decisions.
Laboratory testing plays a crucial role in confirming the diagnosis and guiding treatment decisions. Doctors often collect samples of any discharge or fluid from the eye for culture and sensitivity testing. This process involves growing the infectious organism in the laboratory to identify exactly which bacteria or fungus is causing the problem, then testing which antibiotics or antifungals will be most effective. Blood tests may also be performed to check for signs of systemic infection or underlying conditions that might complicate treatment. The combination of clinical findings and laboratory results allows doctors to distinguish infectious scleritis from other forms of scleritis and develop targeted treatment plans.
Complications
- Infectious scleritis can lead to several serious complications that may result in permanent vision impairment or loss.
- Scleral perforation represents one of the most severe acute complications, occurring when the infection weakens the scleral wall to the point of rupture.
- This emergency situation can lead to collapse of the eye's internal structure and requires immediate surgical repair.
- Even with prompt treatment, perforation often results in significant vision loss and may necessitate complex reconstructive procedures.
- Chronic complications can develop over time, even after successful treatment of the initial infection.
- Scleral thinning and weakening may persist, creating areas of structural vulnerability that could lead to future problems.
- Some patients develop secondary glaucoma due to changes in the eye's drainage system caused by inflammation and scarring.
- Cataracts may form as a result of the inflammatory process or as a side effect of steroid medications used during treatment.
- In the most severe cases, the infection can spread throughout the eye, leading to endophthalmitis, a devastating condition that often results in complete vision loss and may require surgical removal of the eye to prevent spread to surrounding tissues and potentially life-threatening complications.
Prevention
- Preventing infectious scleritis centers on maintaining strict hygiene practices around eye care and promptly addressing any eye injuries or infections.
- For people undergoing eye surgery, following all pre- and post-operative instructions is essential.
- This includes proper use of prescribed antibiotic eye drops, keeping the surgical site clean and dry, and avoiding activities that could introduce contaminants to the healing eye.
- Patients should never touch or rub the operated eye with unwashed hands.
- Proper contact lens hygiene plays a vital role in prevention for lens wearers.
- This includes thorough hand washing before handling lenses, using only sterile solutions for cleaning and storage, replacing lenses according to prescribed schedules, and never wearing lenses when experiencing eye irritation or infection.
- People with underlying health conditions like diabetes should maintain good control of their condition, as poorly controlled diabetes increases infection risk.
- Anyone experiencing eye trauma should seek immediate medical attention, even for seemingly minor injuries.
- Prompt treatment of eye infections, particularly those involving the cornea or conjunctiva, can prevent spread to deeper eye structures.
- People taking immunosuppressive medications should discuss their increased infection risk with both their prescribing physician and eye doctor, ensuring appropriate monitoring and preventive measures are in place.
- While complete prevention isn't always possible, these strategies significantly reduce the risk of developing this serious eye infection.
Treatment of infectious scleritis requires immediate and aggressive intervention with antimicrobial medications tailored to the specific infectious organism.
Treatment of infectious scleritis requires immediate and aggressive intervention with antimicrobial medications tailored to the specific infectious organism. Most patients receive high-dose antibiotics or antifungal medications, often administered both topically as eye drops and systemically through oral medications or intravenous infusions. The choice of specific medications depends on culture results, but doctors typically begin treatment with broad-spectrum antibiotics while waiting for laboratory confirmation of the causative organism.
Topical antibiotic eye drops are applied frequently, sometimes as often as every hour during the initial treatment phase.
Topical antibiotic eye drops are applied frequently, sometimes as often as every hour during the initial treatment phase. Common choices include fortified antibiotics like tobramycin, vancomycin, or fluoroquinolones, which can penetrate the scleral tissues effectively. Systemic antibiotics ensure that therapeutic levels reach all parts of the infected tissue, particularly important when the infection is deep or extensive. Treatment duration typically extends for several weeks, with gradual tapering of medications as the infection resolves.
Surgical intervention may become necessary in severe cases or when medical treatment alone proves insufficient.
Surgical intervention may become necessary in severe cases or when medical treatment alone proves insufficient. Procedures can range from drainage of infected fluid collections to more extensive debridement of infected tissue. In cases where the sclera has become severely damaged or perforated, reconstructive surgery using donor tissue or synthetic materials may be required. Some patients may need temporary or permanent implants to maintain the eye's structure and function.
Supportive care includes pain management, as infectious scleritis often causes severe discomfort that can significantly impact quality of life.
Supportive care includes pain management, as infectious scleritis often causes severe discomfort that can significantly impact quality of life. Anti-inflammatory medications may be used cautiously once the infection is under control, as reducing inflammation too early can sometimes worsen the infectious process. Regular monitoring with frequent follow-up appointments allows doctors to assess treatment response and adjust medications as needed. Recent advances in targeted antimicrobial therapy and improved surgical techniques have significantly improved outcomes for patients with this challenging condition.
Living With Infectious Scleritis
Living with infectious scleritis requires patience and commitment to a comprehensive treatment plan that may extend for months. The immediate focus involves strict adherence to medication schedules, which often include multiple eye drops applied at frequent intervals throughout the day and night. Patients typically need to set alarms to ensure proper timing of medications, as consistency is crucial for treatment success. Pain management becomes an important daily consideration, as the condition often causes significant discomfort that can interfere with sleep, work, and daily activities.
