CORNEAL DEGENERATIONS

Corneal degenerations refers to the conditions in which the normal cells undergo some degenerative changes under the influence of age or some
pathological   condition.

CLASSIFICATION
[A] Depending upon location
I. Axial corneal degenerations
1. Fatty degeneration
2. Hyaline degeneration
3. Amyloidosis
4. Calcific degeneration (Band keratopathy)
5. Salzmann's nodular degeneration.

II. Peripheral degenerations
1. Arcus senilis
2. Vogt's white limbal girdle
3. Hassal-Henle bodies
4. Terrien's marginal degeneration
5. Mooren's ulcer
6. Pellucid marginal degeneration
7. Furrow degeneration (senile marginal degeneration).

[B] Depending upon etiology

I. Age related degenerations. Arcus senilis, Vogt's
white limbal girdle, Hassal-Henle bodies, Mosaic
degeneration.
II. Pathological degenerations: Fatty degeneration,
amyloidosis, calcific degeneration, Salzmann's
nodular degeneration, Furrow degeneration,
spheroidal degeneration, Pellucid marginal
degeneration, Terrien's marginal degeneration,
Mooren's ulcer.
