Wavy lines are most commonly due to macular problems which your ophthalmologist can assess. ...Read more

Can convergence insufficiency be the cause of my daughter's nystagmus? It only presents when looking near and all her tests have came back normal.

Can convergence insufficiency be the cause of my daughter's nystagmus? It only presents when looking near and all her tests have came back normal.

No: Convergence insufficiency is a common cause of visual complaints such as the following list on a standard screening questionnaire.

* one eye drifts or aims in a different direction than the other (this can be subtle). This is significant even if it only occurs when tired or stressed.
* turns or tilts head to see
* head is frequently tilted to one side or one shoulder is noticeably higher
* squinting or closing or covering of one eye
* excessive blinking or squinting
* short attention span
* daydreaming at school/work
* poor handwriting
* poor visual/motor skills (often called "hand-eye coordination")
* problems moving in space, frequently bumps into things or drops things
* clumsiness

While reading or doing close work:
* holds the book or object unusually close
* closes one eye or covers eye with hand
* twists or tilts head toward book or object so as to favor one eye
* frequently loses place and fatigues easily
* uses finger to read
* rubs eyes during or after short periods of reading
* reversals when reading (i.e., "was" for "saw", "on" for "no", etc.)
* reversals when writing (b for d, p for q, etc.)
* omitting small words
* confusing small words
* transposition of letters and numbers (12 for 21, etc.)
* loss of place when reading, line to line and word to word.
* child's ability to learn verbally surpasses his ability to learn visually.

Frequent complains of:
* only being able to read for short periods of time
* headaches or eyestrain
* nausea or dizziness
* motion sickness
* DOUBLE VISION!
It is not a cause of nystagmus. If your daughter has true nystagmus she should have an examination by an ophthalmologist to determine the cause. One can have both conditions but the CI does not cause nystagmus. ...Read more
