|
When do you give bifocals for esodeviations?

1. Pt must be fused at distance with correction (ET with full correction at distance requires surgery).
2. Still ET' with full hyperopic correction. |
|
determine a true from a psuedo divergence excess
|
XT>XT'
Patch for 30 min (keep unfused) remeasure. If XT=XT' it is psuedo, if still >10PD difference it is true |
