What is the treatment of cataract ?
Cataract surgery ( removal of the lens) with or without intraocular implant
If you can’t prescribe lens or glasses
- occlusion therapy to avoid amblyopia

Conservative buckling procedure
Pars plana vitrectomy with or without silicon oil
Treatment of phorias ?
Correction of refractive errors
Orthoptic exercises
Prisms in glasses
Surgical treatment only when diplopia
What is the angle of deviation in infantile esotropia ?
> 30 prism diopter
Treatment of infantile esotropia?
Check if there’s Refractive error
Check for amblyopia
Early surgical treatment

Ambylopia therapy
What is the treatment of partial accommodative refractive estropia ?
CCR
Ambylopia
Surgical correction of residual squint
Treatment of exotropia ?
Check for refractive error and leave for 6 months then you can consider Surgical correction of deviation but no surgery before 6M-1year
When do babies start to have clear vision ?
At 6 months
Determination of deviation is made by what ?
By cover and uncover test
What are the measurements of deviation ?

2- prism cover test
What do we use in Cycloplegic refraction ?
Cyclopentolate 1% and atropine 1%
What is the difference between recession and resection ?
First 1 to weaken the muscle
Resection to strengthen the weak muscle

And visual acuity
What is the treatment of ambylopia ?
Occlusion therapy
