This document discusses different types of serpiginous corneal ulcers, including hyphopyon ulcers, Moorhen's ulcers, and phlyctenular (fascicular) ulcers. Hyphopyon ulcers are characterized by a central, undermined edge and sterile pus in the anterior chamber. Moorhen's ulcers form a crescent-shaped ulcer near the limbus with central and peripheral edges. Fascicular keratitis results from phlyctenules that spread from the limbus along fascicles of blood vessels to the corneal center. Treatment involves removing septic foci, anti-tubercular drugs, anti-helminthics, and local corticosteroids or cautery

HYPOPYON

22. ETIOLOGY
•CAUSATIVE AGENTS
PNEUMOCOCCI (80%)
MORAX-AXENFIELD (10%)
STREPTOCOCCI, STAPHYLOCOCCI, PSEUDOMONAS & FUNGI (10%)
•PREDISPOSING FACTORS
TRAUMA
XEROSIS
ALTERED OCULAR DEFENSE MECHANISMS

23. CLINICAL PICTURES

24. SPECIFIC SIGNS
• * THE ULCER HAS 2 EDGES: -
• - THE CENTRAL EDGE PROGRESSIVE. IT IS CONCAVE AND UNDERMINED.
• - THE PERIPHERAL EDGE THE HEALING EDGE. IT IS CONVEX, SCARRED AND
VASCULAR.
• - HYPOPYON WHICH IS STERILE PUS IN ANTERIOR CHAMBER. IT IS FORMED OF
FIBRIN AND INFLAMMATORY CELLS PRODUCED BY THE SEVERE TOXIC
IRIDOCYCLITIS

25. COMPLICATIONS
* The ulcer is deep with
posterior abscess formation. So
that it commonly perforates and
descemetocele is never formed.

27. MOORHEN’S ULCER

28. DEFINITION
MOORHEN'S ULCER (MU) IS A RARE AND PAINFUL
PRIMARY CHRONIC SERPIGINOUS ULCER WHICH
OCCURS IN THE ABSENCE OF ANY ASSOCIATED
SCLERITIS , AND ANY DETECTABLE SYSTEMIC
DISEASE.

C. PERORATION RARE

31. MANAGEMENT
• TOPICAL STEROIDS
• CONJUNCTIVAL RESECTION
• IMMUNOSUPPRESSIVE CHEMOTHERAPY
• ADDITIONAL SURGICAL PROCEDURES
• SUPERFICIAL LAMELLAR KERATECTOMY
• REHABILITATION

32. FASCICULAR KERATITIS

33. DEFINITION
•A CORNEAL ULCER RESULTING FROM
PHLYCTENULES THAT SPREAD FROM LIMBUS
TO THE CENTER OF CORNEA ACCOMPANIED
BY FASCICLE OF BLOOD VESSELS.

34. ETIOLOGY
ALLERGY TO AN ENDOGENOUS TOXIN:
A. TUBERCULO-PROTEIN
B. INTESTINAL PARASITES
C. SEPTIC FOCI

35. CLINICAL PICTURE
The ulcer starts near the limbus then creeps ( serpiginous )
centrally over the cornea followed by a leash of parallel blood
vessels

36. TREATMENT
GENERAL
1. REMOVE SEPTIC FOCUS
2. ANTI TB DRUGS
3. ANTI HELMINTHS DRUGS
LOCAL
1. CORTICOSTEROID
2. ATROPINE
TREATMENT OF COMPLICATIONS
1. FASCICULAR ULCER (CHEMICAL CAUTERY BY CARBOLIC ACID)
2. FASCICULAR BLOOD VESSELS (ELECTRIC CAUTERY)
