presenting history
Presenting history
  • 50/Indian/Male h/o PTB and DM
  • Left prosthetic eye (trauma 28 yrs ago)
  • Aug 03: R eye redness x 1/52
  • VA® 6/6, peripheral infiltrate with central epithelial defect associated with localized injection and early pannus, CDR of 0.8
  • Imp: R marginal keratitis; glaucoma suspect
  • Treated with gutt Tobradex
  • Epithelial defect healed with an area of localised pannus that appeared inflammed
june 2004
June 2004
  • R eye irritation, redness and blurring of vision x 4/7 (minimal pain)
  • VA® 6/18, area of pannus with 80% peripheral thinning and localised injection, no ED
  • Imp: MK vs Mooren’s ulcer.
  • Treated with gutt FML/ciloxan responded
july 2004
July 2004
  • While steroids were being tailed down, pain and BOV worsened  Steroids stepped up with minimal improvement
  • Peripheral epithelial defect with 60-70% thinning a/w pseudopterygium 5-7 o’clock
  • Imp: R Peripheral Ulcerative Keratitis ?Mooren’s
  • Gutt predforte hourly and gutt ciloxan qds
  • Added oral steroids
  • Right conjunctival resection 17/8/04
  • Histology: ulcer with mixed inflammatory base /no malignancy
  • Oral steroids were tailed down with improved response by late Aug 04
  • Subsequently defaulted FU
progression and management
Progression and Management

Feb 05: flare: 5-8 o’clock thinning

conjunctival resection (2nd) 1/3/05

Oral prednisolone restarted

Defaulted FU

Jun 05: recurrence 5-11 o’clock

Restarted on aggressive topical & oral steroids

progression and management9
Progression and Management
  • Aug 05: Minimal improvement. 3-11 o’clock thinning
    • Oral prednisolone stepped up to 60mg/day
    • Oral cyclophosphamide started
    • conjunctival resection (3rd) 26/8/05
    • Pulsed IV cyclophosphamide commenced 2/52 after 2/52 of oral cyclophosphamide
2/52 later, VA® 6/24, progressive thinning >95% with descematocele : high perforation risk
  • Oct 05 : lamellar keratoplasty complicated by wound leak  resuturing of graft on POD4
  • Recovering well VA 6/24, small persistent epithelial defect.
  • On reducing dose of prednisolone and g tobramycin and pred forte.
  • Currently completed 6 doses of IV cyclophosphamide (25 Jan 06)
treatment summary
Treatment summary
  • Topical steroids with antibiotic cover
  • Oral steroids
  • Oral cyclophosphamide, pulse IV
  • Conjunctival resection x3
  • Lamellar keratoplasty
peripheral ulcerative keratitis
Peripheral ulcerative keratitis

Definition: crescent shaped destructive inflammation of the juxtalimbal corneal stroma associated with an epithelial defect, presence of stromal inflammatory cells, and stromal degradation


  • Rule out CTD first

Causes of PUK
mooren s ulcer
Mooren’s ulcer
  • "chronic serpiginous ulcer of the cornea or ulcus roden "
  • painful, relentless, chronic ulcerative keratitis, with no associated scleritis
  • steep, overhanging

central edge

  • starts in periphery and

may progress centrally or

circumferentially to

involve the entire cornea

idiopathic, with no associated scleritis
  • M:F = 1.6:1
  • Complications: irregular astigmatism, iritis, hypopyon, glaucoma, cataract, perforation (13-36%), blindness
  • Wood T, Kaufman H. Mooren's ulcer. Am J Ophthalmol 1971;71:417-422
  • Unilateral MU - painful progressive corneal ulceration in elderly patients, non-perfusion of the superficial vascular plexus of the anterior segment.
  • Bilateral aggressive MU - young, progresses circumferentially, then centrally in the cornea; vascular leakage and new vessel formation, extending into the base of the ulcer.
  • Bilateral indolent MU - middle-aged patients, progressive peripheral corneal guttering in both eyes, with little inflammatory response; no change from normal vascular architecture except an extension of new vessels into the ulcer
  • Watson PG. Management of Mooren’s Ulceration. Eye, 11: 349-356, 1997
  • Unknown etiology
  • Pathophysiology:
    • Autoimmune (cell-mediated and humoral)
    • still unknown if cell-mediated and/or humoral immune mechanisms are involved directly in the pathogenesis of MU or may be that they just accompany the corneal destruction that is caused by another mechanism
  • Typical ulcer morphology
  • History and physical examination
  • FBC
  • ESR
  • RF
  • complement fixation, circulating immune complexes
  • ANA, ANCA,
  • CXR
  • Scrapings for culture & sensitivity
  • Stepwise approach
    • Topical steroids
    • Oral steroids and Immunosuppressive chemotherapy
    • Conjunctival resection
    • Lamellar keratoplasty/ penetrating keratoplasty
  • Intensive topical steroids
  • Oral prednisolone 60-100mg od
    • Indication - when topical therapy ineffective after 7-10days or topical steroids may be contraindicated because of precariously deep ulcer or infiltrate
conjunctival resection
Conjunctival resection
  • Indication: ulcer progresses despite the steroid regimen
  • conjunctiva adjacent to the

ulcer contains inflammatory

cells that may produce

antibodies against the cornea

and cytokines, which amplify

the inflammation and recruit

additional inflammatory cells

immunosuppressive chemotherapy
Immunosuppressive chemotherapy
  • bilateral or progressive MU that fails therapeutic steroids and conjunctival resection
  • combination of oral prednisolone and an immunomodulatory agent is initiated at the same time.
  • Oral prednisone controls the active inflammatory process until the immunomodulatory agent takes effect (abt 4-6/52).
  • Prednisone is subsequently tapered and the patient maintained on the systemic immunomodulatory agent.
  • Cyclophosphamide
    • Oral
    • IV – 1g monthly IV Cy

  • Cyclosporin A
    • 0.5% Topical CSA

    • Systemic CSA

  • NO comparative studies on type of immunosuppressants and route of administration
additional surgical procedures
Additional surgical procedures
  • Lamellar keratectomy - arrest the inflammatory process and allow healinG
  • Mgmt of perforation – tissue glue, BCL, patch graft

lamellar keratoplasty
Lamellar Keratoplasty
  • Principle: remove necrotic ulcerative cornea thoroughly and to reconstruct anatomical structure of the cornea
  • removes antigenic targets of the cornea
  • eliminates the risk of graft rejection
  • prevents perforation
  • improves vision
