What are the most common types of corneal dystrophies?
The three most common types of stromal corneal dystrophies are: • Dominant Granular Dystrophy — This type of corneal dystrophy usually starts in the first decade and appears initially as small white dots in the center of the cornea. Or, they may appear as lines radiating from the center of the cornea. These dots or white lines will increase in size and number until they start appearing as dense opacities. • Recessive Macular Dystrophy — Usually starting sometime in the first two decades, recessive macular dystrophy is first seen as a thin, superficial veil. However, over time the patient experiences increasing haziness in the central part of the cornea as well as increasing isolated opacities. • Dominant Lattice Dystrophy — This type of dystrophy usually strikes between the ages of 5 and 20 although it has been seen in infants. On examination, the patient may appear to have a lattice of fine lines. By age 40, the center of the cornea may become irregular, with various opacities. Some p
