Which condition is the leading cause of deafblindness?

• A. Histoplasmosis
• B. Ocular albinism
• C. Stickler Syndrome
• D. Uveitis

Answer: (C)

Deafblindness is most often seen when a single condition can impact both sight and hearing. Stickler syndrome is a hereditary connective tissue disorder that affects the eyes and ears. In the eyes it commonly brings high myopia, retinal problems, and sometimes cataracts, while in the ears it leads to sensorineural hearing loss. Because both senses can be affected by this syndrome, it is a well-known and prominent cause of dual impairment, making it the best answer among the options.

Histoplasmosis can damage the eye but isn’t typically a leading cause of deafblindness. Ocular albinism mainly affects vision with normal hearing, and uveitis mainly causes vision problems through inflammation without a consistent association with significant hearing loss.
