Why are my sclera blue?
Blue sclera. As you would expect, this condition is when a normally white sclera has a somewhat blue color. Blue sclera is caused by a congenitally thinner-than-normal sclera or a thinning of the sclera from disease, which allows the color of the underlying choroidal tissue to show through it.
What does a light blue sclera mean?
Congenital defects in collagen synthesis cause thinning of the sclera, which causes a bluish hue on examination. These defects include Ehlers-Danlos syndrome, osteogenesis imperfecta and, occasionally, Marfan’s syndrome.
Which type EDS has blue sclera?
Brittle cornea syndrome has been confused with EDS, particularly EDS type VI (OMIM #225400), which is also associated with blue sclera.
What is the normal color of the sclera?
Normal: In a normal patient, the sclera is white in color and the palpebral conjunctiva appears pink. Unless conjunctiva is diseased you are only visualizing sclera and palpebral vascular bed through the translucent conjunctiva.
Is blue sclera hereditary?
Premature infants frequently demonstrate blue sclerae, particularly those of Caucasian origin. Blue sclera may also occur in isolation as an inherited autosomal dominant or autosomal reces- sive anomaly (Hunt 2002; Hoyt and Taylor 2012).
Can EDS affect your eyes?
Ophthalmological abnormalities in EDS include but are not limited to myopia, retinal detachment and glaucoma. Some of these can be vision-threatening. An optometrist or ophthalmologist should establish a comprehensive baseline for a person with EDS, including a complete eye exam and history.
What is blue sclera associated with?
Bluish sclera is associated with osteogenesis imperfecta, Marfan’s syndrome, Ehlers Danlos syndrome, Blue sclera syndrome (Van der Heave syndrome), incontinentia pigmenti, and many other inherited conditions. [1] The sclera is involved bilaterally in all these conditions and the unilateral appearance is a rarity.
