WATCH: Mum discovers son's sight problem after posting picture on Facebook
A shocked mum discovered her young son has a rare eye condition which needs urgent treatment - after innocently posting a snap of her infant on Facebook.
Christina Doughty, 33, put up the happy snap of her smiling two-and-a-half year old son Miguel so all her friends could see it.
But she was stunned when pal Chantel Riley sent her a message back urging her to get her son's eyes checked - because one showed yellow in the flash rather than red.
Christina, of Southend, went to her GP and then medics alter diagnosed her son as being blind in his left eye which needed urgent treatment if they are to save it.
