Signs
-
The primary signs of both recessive and dominant CHED are corneal edema (swelling or thickening) and corneal opacity, reports missionforvisionusa.org. The recessive version also manifests with involuntary eye movements.
Symptoms
-
Symptoms can include blurred or reduced vision, though the early onset makes it unlikely that this information can be directly conveyed by the child. The condition may also manifest with photophobia, or aversion to bright light.
-
Onset
-
Onset of the recessive version typically occurs at or close to birth. The dominant version typically does not manifest until one to two years of age, reports eyepathologist.com.
Treatment
-
Treatment for the condition is limited but, according to missionforvisionusa.org, may include the use of sodium chloride eye drops or corneal transplantation.
Prevalence
-
Both the recessive and dominant forms of CHED are quite rare, though eyepathologist.com notes that the recessive form occurs more often.
