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] Posterior corneal dystrophies – Fuchs corneal dystrophy presents during the fifth or sixth decade of life. The ...
Congenital opacities may occur as developmental anomalies or following birth trauma. Causes of congenital corneal opacities include sclerocornea, trauma, ulcer, mucopolysaccharidosis, Peter’s anomaly, congenital hereditary endothelial dystrophy. [3] Ocular trauma [10] Corneal ulceration [10] Xerophthalmia, caused by Vitamin A deficiency [10 ...
Macular Corneal Dystrophy is an autosomal recessive genetic disorder caused by mutations in the carbohydrate sulfotransferase gene (CHST6), resulting in abnormal proteoglycan synthesis. The accumulation of abnormal glycosaminogycans in the corneal epithelium and stroma leads to progressive opacification of the cornea and subsequent loss of ...
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 ...

Fuchs dystrophy, also referred to as Fuchs endothelial corneal dystrophy (FECD) and Fuchs endothelial dystrophy (FED), is a slowly progressing corneal dystrophy that usually affects both eyes and is slightly more common in women than in men. Although early signs of Fuchs dystrophy are sometimes seen in people in their 30s and 40s, the disease ...
Granular corneal dystrophy is caused by a mutation in the TGFBI gene, located on chromosome 5q31. [4] The disorder is inherited in an autosomal dominant manner. [5] This indicates that the defective gene responsible for the disorder is located on an autosome (chromosome 5 is an autosome), and only one copy of the gene is sufficient to cause the disorder, when inherited from a parent who has ...
