Tension Test for B2

B2 has to be warded into KK to do a tension test for his eye lid. His eyelids had drooped down a lot over the last few years. He had seen the eye doctor at TTSH who think that it's normal for him to have a droopy eyelid since mum has also lose some of her double eyelid. The doctor made this conclusion despite me telling him that mum's eyelids started to droop after 40 while B2's eyelid started drooping since 12. Angel, please help KKH doctor to find out the problem with B2 and treat him.
