14. Case 4: 4 mo, F
• E(T) = 25PD
• SAC: +2.00 OU
• Controlled for 2 years
• Then MX(T)
• Between ages 5-8, sometime MET,
sometimes MXT

15. Case 4: 4 mo, now 8
• 20PD X(T) w DVD
• Best correction:
• OD: -0.25 20/25
• OS: -1.00 -0.50 x 180 20/20
Risk Factors
• Variable monofixation?
• Amblyopia
• DVD
• E(T) recurrence

16. Take home message
• Spontaneous consecutive exotropia can occur:
• Accommodative esotropia
• Infantile esotropia (managed with prisms)
• Nonrefractive Accommodative ET with or without
high AC/A
• Intermittent esotropia
• Recognize risk factors
• Taper earlier than we were taught

17. Possible Risk Factors
•Poor follow-up
•Wrong prescription
•High AC/A
•Prematurity
•Rapid control of deviation
•Rapid drop in refraction
•Amblyopia
•DVD
•IOOA
•Remote NPC

18. Management Pearls
• Full cycloplegic refraction
• 2 cycles good control: consider reduce plus 1-1.5D
from full cycloplegic refraction
• Intermediate or Short acting cycloplegic refraction
• If ET controlled, No need to run after latent
hyperopia if ET controlled with Rx
• Iff residual ET, proceed with atropine refraction
• Closer follow-up than we were used to
