Presentation
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]
[…] inflammatory cells and neovascularization are present within adjacent stroma in some cases. [entokey.com]
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]

- Corneal Opacity

The association of HOAs and corneal opacity varied among the corneal dystrophies. [journals.plos.org]
It is not clear why a single mutation can cause several corneal opacity patterns. However, atypical corneal opacity patterns may be characteristic of late-onset lattice corneal dystrophies. [molvis.org]
HISTORY A hereditary type of corneal dystrophy, or "nodular corneal opacities," was first described by Groenouw, 1 in 1890. [jamanetwork.com]
Slit lamp examination of the corneas will be performed, and the presence or absence of corneal opacities, whether characteristic or not of a TGFBI dystrophy, will be documented on the CRF form. [clinicaltrials.gov]
- Photophobia
Type II generally does not cause vision problems until later in life Symptoms - Corneal dystrophy- lattice- type 2 * Progressive vision loss * Photophobia Causes - Corneal dystrophy- lattice- type 2 Not supplied. [checkorphan.org]
An abnormal sensitivity to light (photophobia) and the sensation of foreign material within the eye may also occur. [cornealdystrophyfoundation.org]
Corneal erosions are very painful and can cause sensitivity to bright light (photophobia). Lattice corneal dystrophy type I is usually bilateral, which means it affects both eyes. [ghr.nlm.nih.gov]
Patient remains asymptomatic until epithelial erosions precipitate acute episodes of ocular hyperemia, pain, and photophobia. [ipfs.io]
In addition, the RCEs themselves cause pain and photophobia. Treatment is always case specific, but it is initially aimed at treating the RCEs to reduce the pain and photophobia. [reviewofoptometry.com]
- Blurred Vision
Such material may cause the cornea to lose its transparency potentially causing loss of vision or blurred vision. [cornealdystrophyfoundation.org]
Painless blurred vision sometimes begins after sixty years of life, in Granular corneal dystrophy multiple small white discrete irregular spots that resemble bread crumbs or snowflakes become apparent beneath Bowman zone in the superficial central corneal [wikivisually.com]
Painless blurred vision sometimes begins after sixty years of life. [ipfs.io]
Males often have blurred vision, and the condition is progressive. Females are usually asymptomatic, and the disease is nonprogressive. [reviewofcontactlenses.com]
The proband is a 20 year-old boy (IV-4) who was initially brought to hospital in Zhengzhou for evaluation of blurred vision, irritation, tearing and often photophobia. Visual acuity was normal (1.2 in both eyes). [omicsonline.org]
- Progressive Loss of Vision

Progressive visual loss. Guttae alone may not cause corneal edema, and mild cornea edema may not result in decreased vision. More severe disease associated with decreased vision often has epithelial and stromal edema and fibrosis. [journals.lww.com]
- Diplopia
Some individuals may have decreased clarity of vision (visual acuity), blurred vision, and double vision affecting only one eye (monocular diplopia). [cornealdystrophyfoundation.org]
Symptoms EBMD can be asymptomatic, associated with painful erosive episodes and/or may cause decreased vision by inducing mild irregular astigmatism (monocular diplopia, “ghost” images). [journals.lww.com]

It is of interest that ocular findings (lattice dystrophy and vitreous opacities) may be the presenting feature in at least two forms of amyloidosis or occur as part of a polyneuropathy syndrome. [nejm.org]

Other Pathologies
- Amyloid Plaque
Because the stroma between is relatively clear early on, vision is fairly good until later in life when the lattice lines spread to the periphery of the cornea and amyloid plaques form. [reviewofoptometry.com]
Treatment
Treatment Treatment Options: Recurrent corneal erosions benefit from standard treatments while penetrating keratoplasty may be necessary by the fifth decade to improve acuity. [disorders.eyes.arizona.edu]
Beginning with basic science, examination techniques and epidemiology, the following chapters discuss the diagnosis and the medical and surgical treatment of numerous different conditions and diseases that may affect the cornea. [books.google.com]
Treatment focuses on relieving erosions with antibiotics and bandage contact lenses. [rarediseases.info.nih.gov]

Onset of corneal changes in lattice corneal dystrophy type II occurs at age 30-40 years, but most patients do not experience symptoms until their seventh decade of life. [2] Prognosis Lattice corneal dystrophy demonstrates variable penetrance and expression [emedicine.medscape.com]
Recognizing a corneal dystrophy is important for prognosis of vision loss and early treatment to help avoid future vision loss. [reviewofoptometry.com]

Therefore, any unusual pattern of corneal opacities associated with corneal neovascularization is not a dystrophy and clinicians should investigate other etiologies. [reviewofoptometry.com]
Today, we have a multitude of tools at our disposal to investigate the etiology of disease. [reviewofcontactlenses.com]
As interest in molecular etiology of keratoconus continues, we anticipate future new insights into the true genetic basis of this highly prevalent corneal disease. [journals.lww.com]

Pathophysiology
Thus, LCD1 seems to represent an epithelial-stromal entity, because both, the epithelial cells and keratocytes are pathophysiologically involved. [iovs.arvojournals.org]
The identification of the mutation responsible for the corneal dystrophy is a critical step toward understanding the pathophysiology of the formation of the deposits. [reviewofoptometry.com]

Pathophysiology The cornea is the clear outer coat of the front of the eye. A dystrophy of the cornea is defined as a bilateral noninflammatory clouding of the cornea. [emedicine.medscape.com]
Pathophysiology As with other amyloid diseases, LCD2 is based on misfolded proteins forming β-sheets instead of α-helices creating fibrillar amyloid structures that accumulate in affected organs to cause pathology. [webeye.ophth.uiowa.edu]
