When does vision stop deteriorating in children who wear glasses?

Question

I have a sixteen year old daughter who has needed new glasses every six months for the past four years. She has previously been diagnosed with convergence insufficiency and a Mittendorf dot. She got her first pair of glasses at age nine. Bad vision runs in the family, nine out of 12 of her immediately family members also wear glasses, but none of them have showed the constant, chronic deterioration in vision she is experiencing. Her vision has gone from -1 to -4 diopters over the past four years, which maps to about 20/200. She is severely hearing impaired so crystal clear vision is very important to her to maximize her ability to read lips. Her opthamologist has been useless other than to issue new prescriptions. Yes I know, get another doctor, unfortunately easier said than done given my insurance plan. Any ideas about what might be causing this, when it might stop, or things we can investigate to make it stop?

Answer 1

it is indeed a difficult situation, first of all, till the time the body is growing and the contours of the skull are changing, her vision will continue to change. lasik surgery is probably not advisable for the same reason till that time either. the growth will probably stop by age 18-20. it is expensive to get another opinion, you can consider a one time opinion to verify this or whatever your primary opthalmologist is doing, good luck
