Hi, The dose of
Budecort given through inhaler for 4 months is not a dose high enough to cause major
steroid side effects. Now your daughter's vision problem seems to be unrelated to this. 3 years is also unfortunately an age where children get interested in watching television for prolonged period, in comfortable but not very correct postures. It could lead to the beginning of an
eye strain and later development of a habit of seeing more through one eye. Now, you must check her posture promptly and more often. Also an eye test will be helpful.It is a common problem and if corrected promptly, will help her in future.
