Scleritis

Patient will present as → a 42-year-old female presents to the clinic with complaints of a deep, aching pain in her right eye for the past week. She reports that the pain worsens with eye movement and has been severe enough to disrupt her sleep. She also notes redness and blurred vision in the affected eye but denies discharge or itching. Her medical history includes rheumatoid arthritis, diagnosed five years ago. On examination, the right eye shows diffuse redness involving the sclera and episclera with tenderness on palpation. Vision is mildly reduced in the affected eye. There is no evidence of discharge, corneal involvement, or proptosis. A slit-lamp examination reveals inflammation of the sclera without thinning or necrosis, consistent with diffuse anterior scleritis. Initial management includes oral NSAIDs, such as indomethacin, to reduce inflammation and relieve pain. The patient is referred to a rheumatologist for further evaluation and consideration of immunosuppressive therapy, such as methotrexate, if NSAIDs are insufficient. Close follow-up with an ophthalmologist is arranged to monitor response to treatment and evaluate for complications, such as scleral thinning or posterior scleritis.

Inflammation of the sclera (the white outer coating of the eye) associated with systemic immunologic disease, such as rheumatoid arthritis

  • It causes significant eye pain (severe, deep pain), redness, photophobia, and reduced vision; pain often worsens with eye movement
  • Types:
    • Diffuse anterior scleritis (most common, least severe)
    • Nodular anterior scleritis (localized nodules)
    • Necrotizing scleritis (severe, may lead to scleral thinning and perforation)
    • Posterior scleritis (rare, affects deeper scleral layers and adjacent structures)

On examination, there is ocular redness and pain on palpation of the eyeball. It can cause visual impairment

  • Labs should include screening for systemic immunologic diseases, such as ANCAs, ANA, CRP, ESR, Lyme, RA, ACE, RPR, etc.

Refer the patient for prompt evaluation by an ophthalmologist

  • NSAIDs (e.g., indomethacin) are effective for mild cases like diffuse or nodular  anterior scleritis
  • Glucocorticoids (e.g., prednisone 1 mg/kg/day) for severe cases or those unresponsive to NSAIDs
  • Immunosuppressive agents (e.g., methotrexate, mycophenolate mofetil, or cyclophosphamide) for necrotizing scleritis or systemic disease involvement
  • Biologic therapies (e.g., rituximab or TNF-alpha inhibitors) for refractory or severe cases
  • Referral to an ophthalmologist + rheumatologist is essential for proper management and to address underlying systemic conditions
Question 1
A 69-year-old female with scleritis and has been taking 600 mg of ibuprofen three times per day. She presents for a follow-up and stated she had not had any improvement in her symptoms after 7 days. What is the next best treatment option at this time?
A
Prescribe oral prednisone 1 mg/kg/day for one month
B
Prescribe topical prednisolone acetate 1% four times per day for one week
Hint:
Topical steroids can be used as the first-line agent in addition to oral NSAID treatment.
C
Discontinue ibuprofen
Hint:
The patient has not responded to first-line treatment but requires additional treatment to manage inflammation.
D
Prescribe topical artificial tears four times per day
Hint:
Artificial tears do not manage inflammation. They may provide some relief to any ocular surface dryness present.
Question 1 Explanation: 
If there is no response with the first-line treatment of oral NSAIDs, then second-line treatment of oral steroids is indicated.
Question 2
A 58-year-old woman has severe, boring pain in her right eye that wakes her at night. The eye has a deep, violet-red color. She also has 1 hour of morning stiffness and symmetric swelling of the knuckles (MCP joints) of both hands. Which of the following underlying conditions is most likely?
A
Osteoarthritis
Hint:
Osteoarthritis is not inflammatory and isn't linked to eye inflammation.
B
Gout
Hint:
Gout rarely involves the eye and doesn't cause symmetric MCP swelling.
C
Rheumatoid arthritis
D
Fibromyalgia
Hint:
Fibromyalgia causes no tissue inflammation.
E
Hypothyroidism
Hint:
Hypothyroidism doesn't cause scleritis. Graves disease causes thyroid eye disease with bulging eyes.
Question 2 Explanation: 
Scleritis is inflammation of the deep white wall of the eye, and it is often tied to a systemic autoimmune disease. Rheumatoid arthritis is the classic cause, and granulomatosis with polyangiitis and relapsing polychondritis are others. New scleritis should prompt a search for, or better control of, the underlying disease.
Question 3
A 52-year-old man has had 1 week of severe, deep right eye pain that spreads to his brow and jaw and wakes him at night. The eye is tender to touch and has a bluish-violet hue from engorged deep vessels. The cornea is clear, the pupil reacts normally and eye pressure is normal. There is no discharge. Which of the following is the most likely diagnosis?
A
Episcleritis
Hint:
Episcleritis causes mild discomfort at most and a bright red, not violet, color.
B
Viral conjunctivitis
Hint:
Viral conjunctivitis causes watery discharge and grittiness, not deep, severe pain.
C
Scleritis
D
Subconjunctival hemorrhage
Hint:
A subconjunctival hemorrhage is painless.
E
Acute angle-closure glaucoma
Hint:
Angle closure gives a hazy cornea, a fixed mid-dilated pupil and high eye pressure.
Question 3 Explanation: 
Scleritis causes severe, boring eye pain that often wakes people at night, a tender eye, and a deep violet-red color from engorged deep vessels. Episcleritis is much milder, with little or no pain and bright red surface vessels. Scleritis can threaten vision, so refer to ophthalmology and look for an underlying autoimmune disease.
