1. Infectious Keratitis
OCULAR, LOCAL, MOST SEVERE
DISEASE
2. Systemic causes (includes infection)
3. Blepharitis associated disease
OCULAR, LOCAL, LESS SEVERE
NON INFECTIOUS DISEASE
17. Kanski: Characteristics of INFECTIVE vs STERILE
corneal infiltrates
Size Tend to be larger Tend to be smaller
Progression Rapid slow
Epithelial defect Very common and
larger when present
Much less common
and if present tend to
be small
Pain Moderate to severe mild
Discharge Purulent mucopurulent
Single or multiple Typically single Commonly multiple
Unilateral or bilateral Unilateral Often bilateral
AC Rxn Severe mild
Location Often central Typically
peripheral
Adjacent corneal rxn Extensive limited
18. Features HSV marginal
ulcer
Staph. marginal

Etiology Active HSV Immunologic response
to staph. antigen
Epithelial
defect Always
Absent (if present, late)
Neovasc. Often Never

Blepharitis Unrelated Usually

26. I. Blepharitis Assoc. Keratitis
includes:
1. Marginal keratitis
2. Phlyctenulosis
3. Ocular Rosacea
LOCAL CAUSES
27. I. Blepharitis Associated Keratitis
ABSENT PRESENT
Less than 2 clock
hours of the
peripheral cornea
Less ulcerative
tendency
Does not progress
centrally
LOCAL CAUSES
28. Signs of blepharitis
ABSENT MILDLY PRESENT
crustiness,
collarettes, flaking
telangiectasia of
eyelids and face
chronic papillary
conjunctivitis
meibomian gland
dysfunction
LOCAL CAUSES
29. Marginal keratitis
ABSENT PRESENT
surrounded by 1mm clear
zone
Anterior stromal infiltrate
Usually less than 1 clock hour
long
Predilection for 2, 4, 8, 10
oâclock positions
In some cases multiple
infiltrates can coalesce to
form a larger ring infiltrate
LOCAL CAUSES
31. Phlyctenulosis
ABSENT PRESENT
pinkish white nodule usually
originating at limbus
as lesion evolves the elevated
nodule ulcerates
recurrent lesions extend
farther toward central cornea
LOCAL CAUSES
32. LOCAL CAUSES
Ocular Rosacea
ABSENT PRESENT
some infiltrates ulcerate
and can perforate
cutaneous signs need not be severe for
ocular involvement
diffuse gray opacification of peripheral
stroma with superficial vascularization
Severe cases develop recurrent
peripheral infiltrates central to
peripheral vascularization

36. Some questions we want answered
â˘Is this red eye infectious?
â˘Is this red eye autoimmune?
â˘Is this red eye blepharitic?
â˘None have been answered
completely but we have
identified the next steps
37. To address infection & autoimmunity:
⢠herpes antibody titers
⢠Lyme titer
⢠FT-ABS, VDRL
⢠Culture the infiltrate
⢠antithyroid peroxidase antibodies
⢠Anti SSA and anti SSB
⢠Rheumatologic consultation
38. To address blepharitic causes:
â˘Antibiotic ointment
â˘Educate pt to greater
attention to lid hygiene
â˘Responsiveness to
doxycycline
