Describe Angular Blepharitis
what bacteria causes it, signs, symptoms, treatment
- Maroxella or Staph. atopy
- Red, flaky, ulcerative canthal regions (lateral > medial), irritation, tenderness
Tx: Zn sulfate (maroxella) or bacitracin (straph)
Describe hordoleum
what it is, treatment
- red, painful tender nodule
- can be internal or external
- infectious
- drain by removal of lash, lance at peak and excision, leave scar tissue

Describe Chalazion
how are signs and symptoms different than from a hordoleum
- Granuolmatous
- non-infectious, non-painful, no redness or inflammation
- Secondary to hordoleum
- Compresses, may induce astigmatism if large
- Tx: excision and biopsy
Your patient that previously had a hordoleum now has a granulomatous that has begun to induce astigmatism. What is the most likely diagnosis?.
A. Angular Blepharitis B. Hordoleum C. Chalazion D. Concretion E. Distichiasis F. Pediculosis/Phthiriasis Palpebrum
C. Chalazion
Describe Concretion
calcified sebaceous material
Your patient presents with calcified sebaceous material. What is the most likely diagnosis?.
A. Angular Blepharitis B. Hordoleum C. Chalazion D. Concretion E. Distichiasis F. Pediculosis/Phthiriasis Palpebrum
D. Concretion
Describe Distichiasis
- extra row of lashes typically grows from meibomian gland orifacea
- Complications: trichiasis, corneal foreign body sensation and tracking
Describe Pediculosis/Phthiriasis Palpebrum
Pediculosis - body louse
Phthiriasis - crab louse
Symptoms: discharge, red lid margin
Signs: translucent lice, fecal material, dark red/brown granules
- Palpable pre-auricalar node
- must treat underlying infection
Ocular Tx: vasoline, physiostigmine, yellow mercuric oxide
Your patient presents with extra row of lashes from MG orifices. They complain of trichiasis, corneal foreign body sensation and tracking. What is the most likely diagnosis?.
A. Angular Blepharitis B. Hordoleum C. Chalazion D. Concretion E. Distichiasis F. Pediculosis/Phthiriasis Palpebrum
E. Distichiasis
Your patient presents with discharge and red lid margins. Upon SLE you see translucent lice and fecal granules. What is the most likely diagnosis?.

F. Pediculosis/Phthiriasis Palpebrum
What is the treatment for Pediculosis/Phthiriasis Palpebrum?
A. Zn sulfate or bacitracin
B. Drain by removal of lash, lance and excision
C. Vasoline, physostigmine, yellow mercuric oxide
C. Vasoline, physostigmine, yellow mercuric oxide
Note: Red, Kwell, Nix (treatment lice infestation) is corneal toxic
