    ### Response:
    What are the signs and symptoms of Coats disease? The signs and symptoms of Coats disease typically begin at an early age (between ages 6 and 8). Some people may only have a few or no symptoms, while others are very severely affected. The condition is almost always progressive (symptoms get worse over time), although alternating periods of sudden worsening with periods of no apparent progression are common.
