Corneal flattening or thinning and endothelial opacities may also be present. A prominent Schwalbe’s line, as well as iris and angle findings, may also be present. [reviewofcontactlenses.com]

LCD variants present later in life than classic LCD. LCD type IIIA presents in the 5th-7th decade, usually with epithelial erosions. It has thicker lattice lines, described as "ropy-appearing", which extends to the limbus. [webeye.ophth.uiowa.edu]

Long Arm
Meesmann corneal dystrophy has been linked to mutations to two separate genes, one (KTR3) on the long arm of chromosome 17 (17q12) and one (KTR12) on the long arm of chromosome 12 (12q13). [cornealdystrophyfoundation.org]

Symptoms usually become apparent in childhood or adolescence and may include separation of layers of the cornea (corneal erosions), decreased vision, photosensitivity, and eye pain. [rarediseases.info.nih.gov]
[…] that causes Meesmann dystrophy has been localized to two keratin-specific genes, KRT3 on chromosome 12q12 and KRT12 on chromosome 17q12, making Meesmann dystrophy a category 1 corneal dystrophy. 6 Treatment is initially targeted to treat the pain and photosensitivity [reviewofoptometry.com]
