Comprehensiveness

On this resource, the following formatting is used for comprehensiveness:

  • Minimal depth
  • (Moderate depth)
  • ((Comprehensive))

Gross processing

  • Inspect
  • Measure
  • Serially section in 3-4 mm wide slices.

Example gross report:

(Labeled: ___. The specimen is received in formalin and consists of an) << opaque / translucent>> corneal disc measuring __ cm in diameter and __ cm in thickness. The specimen is serially sectioned and entirely submitted for microscopic examination in one cassette.

Microscopic examination

 
Corneal subepithelial acute inflammation, seen as the presence of neutrophils, as well as chronic inflammation, seen as plasma cells and lymphocytes. There is an associated neovascularization. Bowman's membrane is disrupted. The findings are non-specific.

Look for integrity of Bowman's and Descemet's membranes.

For corneal opacities, look for the most common causes, which generally manifest as:[1]

  • Inflammation and edema
  • Traumatic injury

Reporting

Example:

(Right eye cornea, excision:
Cornea with)
patchy acute and chronic inflammation, nonspecific, with disrupted Descemet's membrane and associated neovascularization.
