Disease Profile
Superior limbic keratoconjunctivitis
Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Inheritance
Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease.
Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype.
X-linked
dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.
dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.
X-linked
recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.
recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.
Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.
Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Summary
Superior limbic keratoconjunctivitis (SLK) is a chronic and recurrent eye disease which affects the superior bulbar conjunctiva (the clear layer that covers the eyeball, over the sclera) and tarsal conjunctiva (the clear layer that lines the eyelids), as well as the superior limbic aspect of the cornea (the area above the cornea).[1][2] It is commonly found in women 20-70 years of age. The signs and symptoms include burning, redness and irritation and tend to develop slowly over a period of 1 to 10 years.[3] Vision usually remains intact. While the underlying cause of SLK remains unknown, it is believed that the condition is secondary to superior bulbar conjunctiva laxity. Factors inducing conjunctiva laxity include thyroid eye disease (usually hyperthyroidism), tight upper eyelids, and prominent globes.[1][2][3] A mimicking disorder has been encountered in soft contact lens (SCL) wearers, typically with exposure to thimerosal-preserved solutions.[2] Treatment of SLK may involve the use of various medications, surgery, or a combination of both.[4]
Cause
A different condition, known as Contact Lens-Induced Superior Limbic Keratoconjunctivitis (CLSLK) is an eye inflammatory condition with an almost identical presentation, but it is related to contact lens wear.[6]
Treatment
- Silver nitrate (antiseptic) solution
- Mast
cell stabilizers (used to prevent or control allergic reactions) - Vitamin A preparations
- Cyclosporine A
- Autologous (self) serum–derived drops
- Botulinum injection to the overlying muscle
Surgical options include cryotherapy (use of cold to destroy abnormal
