Stickler syndrome is a group of hereditary conditions affecting connective tissue. Stickler syndrome is characterized by ocular findings, distinctive facial abnormalities, hearing loss, skeletal abnormalities, and joint problems.
Eye findings may include high myopia, cataract, vitreoretinal or chorioretinal degeneration, and retinal detachment. Hearing loss can be both conductive and sensorineural. Affected individuals have a characteristic flattened facial appearance caused by midfacial underdevelopment and cleft palate.
Stickler syndrome is inherited in an autosomal dominant or autosomal recessive manner. Stickler syndrome affects approximately 7,500 to 9,000 newborns.
