Epithelial basement membrane dystrophy (EBMD) is a disorder of the eye that can cause pain and dryness. EBMD, also known as map-dot-fingerprint dystrophy and Cogan microcystic epithelial dystrophy , is a corneal epithelial disease that may result in recurrent corneal erosions , irregular corneal astigmatism , and decreased vision.
Most cases of recurrent corneal erosion are acquired. There is often a history of recent corneal injury, such as corneal abrasion or ulcer, but also may be idiopathic or due to corneal dystrophy or corneal disease. In other words, one may develop corneal erosions as a result of another disorder, such as epithelial basement membrane dystrophy ...
Lattice dystrophy starts as fine branching linear opacities in Bowman's layer in the central area and spreads to the periphery. Recurrent corneal erosions may occur. The hallmark of Schnyder corneal dystrophy is the accumulation of crystals within the corneal stroma which cause corneal clouding typically in a ring-shaped fashion. [citation needed]
Lattice corneal dystrophy: Lattice corneal dystrophy is an autosomal-dominant characterized by amyloid deposition in the corneal stroma. Due to deposits, lattice-like ...
Corneal pachymetry may be useful in confirming the diagnosis. Treatment usually consists of vision correction with eyeglasses or contact lenses. Intacs implants, corneal collagen cross-linking, and corneal transplant surgery are additional options. Surgery is reserved for individuals who do not tolerate contact lenses.
Treatment is required in the latter case to combat loss of vision. [7] The white dots usually disappear naturally. Corticosteroids have been shown to speed up this process. The differences in the immune response of each patient may contribute to the differences seen between the white dot syndromes. [8]
Occult macular dystrophy (OMD) is a rare inherited degradation of the retina, characterized by progressive loss of function in the most sensitive part of the central retina , the location of the highest concentration of light-sensitive cells (photoreceptors) but presenting no visible abnormality.
Malattia Leventinese (or Doyne’s honeycomb retinal dystrophy) is another maculopathy with a similar pathology to wet AMD. Hypotony maculopathy: Maculopathy due to very low intraocular pressure (ocular hypotony). [2] Cellophane Maculopathy A fine glistening membrane forms over the macula, obscuring the vision. [3]
