• Review the clinical images for several corneal pathologies
• Review the key diagnostic features of those pathologies
• Review the treatment modalities and long-term management for each condition

In this video case-based course, Dr. Sanjay Sharma, Dr. Christopher Rapuano, and Dr. Melissa Barnett will walk participants through the important aspects of several cornea-related clinical cases. Test your knowledge with this quiz-style presentation where the lecturers will show a clinical image, allow time for the viewer to attempt a diagnosis, and then review the correct answer.

In this video, the lecturers will review:

• 15 different cases related to a variety of corneal pathologies
• The key diagnostic features used to identify several corneal diseases
• The treatment modalities and long-term management for those conditions

Before moving on to the lecture, take a moment to examine the image below. An 82-year-old presents with a chronic red eye. What corneal pathology is noted?

• Herpes simplex keratitis

  Herpes simplex is a viral infection in which there is activation of the virus in the sensory nerve fibers. Classically, epithelial involvement is seen with a dendritic pattern of staining. This is not present here.

• Band keratopathy

  CORRECT

  Band keratopathy is the correct answer. In this condition, calcium deposits in Bowman's layer, the epithelial basement membrane and the anterior stroma. This is a form of dystrophic calcification as calcium is deposited in tissue that is degenerated from a variety of causes including systemic or local inflammation, infection, medication or injury.

• Munson's sign is present

  Munson's sign is seen in keratoconus. Here when a patient looks down, an abnormally shaped cornea causes a v-shaped distortion of the lower lid.

• Mooran's ulcer is present

  Mooran's ulcer is a peripheral ulcer; the pathology here is central in nature. Additionally, the image is not consistent with an ulcer.
