Necrotizing Scleritis in Wegener’s Granulomatosis
  • by Peter Maris, Jr.
2
Patient History
  • 59 y/o Hispanic male with hx. biopsy-proven Wegener’s granulomatosis c/o redness and boring pain in both eyes x 2 months, OS worse than OD.
  •          Pt. also reports minimally decreased vision in OS over past several weeks.
3
Past Medical History
  • Wegener’s diagnosed in ’98 when pt. presented with cough, hemoptysis and myalgias. Lung biopsy positive.
  • hx. recurrent sinus disease.
  • End-stage renal disease (on hemodialysis 3x/week).
  • s/p several treatments with cytoxan and solumedrol – last cytoxan tx. 7 months prior.
  • past cytoxan treatments complicated by leukopenia and opportunistic infections (VZV and CMV).
4
"Medications:"
  • Medications: Coumadin, Oscal, Nephrovite, Fosamax, Indomethacin – 75mg BID, Artificial Tears – 0/2
  • POHx.: No hx. surgery or trauma; wears bifocals
5
Clinical Exam
  • Va(w/gl.): OD  20/25
  •                      OS  20/50   ph>  20/30
  • Pupils: reactive OU, no APD
  • Motility:  full OU
  • External: no proptosis, no resistance to retropulsion; pain on mild palpation OU
6
Slit Lamp Exam
  • l/a – WNL OU
  • c/s – injection of superficial and deep episcleral vessels OU; edematous sclera and episclera OU; bluish hue to sclera superiorly, particularly OS.
  • K- limbal stromal haze OU
  • AC – deep and quiet OU
  • I/L – WNL and clear OU

Additional Exam
  • Tonometry:  13 mm Hg OU
  • Topical phenylephrine (10%): no blanching of scleral vessels OU
  • Dilated Fundus Exam: no disc swelling, no choroidal folds or exudative retinal detachment, no retinal hemorrhages
  • Fluorescein Angiogram: unremakable

Treatment
  • Overnight hospitalization for:


  •   Solumedrol – 1 gram IV  x  1
  •   Cytoxan (Cyclophosphamide) – 500 milligrams  x 1

Scleritis – differential diagnosis (common)
  • Wegener’s granulomatosis
  • rheumatoid arthritis
  • relapsing polychondritis
  • systemic lupus erythematosis
  • Reiter’s syndrome
  • polyarteritis nodosa
  • ankylosing spondylitis
  • herpes zoster ophthalmicus
  • syphilis
  • gout
13
Scleritis – differential diagnosis (less common)
  • tuberculosis
  • Lyme disease
  • sarcoidosis
  • parasitic infections
  • other bacteria (Pseudomonas species)
14
Wegener’s Granulomatosis - triad
  • necrotizing granulomatous vasculitis of the upper and lower respiratory tracts
  • variable degrees of small-vessel vasculitis
  • focal necrotizing glomerulonephritis
15
Ophthalmic Manifestations
  • Bullen CK et al. Ocular Complications of Wegener’s Granulomatosis. Ophthalmology, 1983.
  • 140 pts. with biopsy-proven Wegener’s were examined at Mayo Clinic, btw. 1966 –1982
  • 40 pts. (28.6%) had ophthalmic complications
  • substantial mortality/ ocular morbidity:
  •              4 patients died
  •              3 eyes were enucleated
16
Sites of Involvement
  •                       No. of Patients     Percentage(%)
  • Orbital                      18                                45
  • Scleral/Episcleral     15                                38
  • Corneal                     11                                28
  • Conjunctival              6                                 15
  • Eyelid                        8                                 20
  • Nasolacrimal             10                               25
  • Optic Nerve               9                                 25
  • Retinal                       7                                 18
  • Uveal                         4                                 10



17
Treatment - Scleritis
  • Non-necrotizing anterior scleritis: oral non-steroidal anti-inflammatory drugs
  • more severe: oral corticosteroids
  • necrotizing scelritis: immunosuprssive agents w/wo systemic steroids
18
Recommendations of an Expert Panel
  • Jabs DA et al. Guidelines for the Use of Immunosuppressive Drugs in Patients with Ocular Inflammatory Disorders. American Journal of Ophthalmology 2000.:
  • Cyclophosphamide – starting at 2mg/kg is the preferred drug for necrotizing scleritis in setting of systemic vasculitis.
  • concomitant steroid therapy should be initially started as well, which can then be tapered over first 2-4 months of cytotoxic therapy.
19
Side Effects of Cyclophosphamide
  • bone marrow suppression (granulocytopenia and lymphopenia)
  • risk of opportunistic infections (P. carinii)
  • hemorrhagic cystitis
  • teratogenicity (contraindicated in pregnancy)
  • alopecia
20
In Summary
  •        Scleritis, particularly necrotizing scleritis, can both jeapordize the integrity of the eye and be representative of a life-threatening systemic vasculitis.
  •         Appropriate aggressive treatment, often with immunosuppressives, is important for preserving the eye and preventing nonocular morbidity.
