3) Orthoptic - Orthoptics is a specialty affiliated with the eyecare profession that main focus is on strabism (wandering eye), amblyopia (lazy eye) and eye movement disorders treatment and non-surgical management.

4) Electroretinography -  Electroretinography (ERG) is an eye test that measures retinal activity (the part of the eye that detects light).

5) Aphakia  -  Aphakia is the loss of the eye's lens due to surgical intervention, such as a perforating wound or ulcer, or congenital defect in cataract surgery.
