2. What is Latent Squint?!
It’s a condition where the eyes have a
tendency to become misaligned when
not being used e.g. when the eye is
covered.
However, when being used normally,
the eye remains straight.
3. How does this happen?
This correction of tendency to deviate is corrected by
continuous effort of binocular Fusion By the brain. (week
4)
This is done by combined use of the sensory and motor
systems.
The motor system acts to fixate both eyes at specific
object
Any offset is detected visually (and the motor system
corrects it)
Heterophoria only occurs during dissociation of the left
eye and right eye (absent fusion)
If you cover one eye (with your hand) you remove the
sensory information about the eye's position in the orbit.
Without this, there is no stimulus to binocular fusion, and
4. How common is Latent Squint?
Very common! Almost all individuals
have some degree of heterophoria even
very small.
Do People with latent squint see
double?
NO, Never! Thanks to your Brain.
I have Latent Squint, Will it go Manifest?
Usually No! Don’t worry!
5. How would I know if I have Latent
Squint or not?!
You will never know by yourself, It’s
usually Asymptomatic.
But Your Ophthalmologist can tell you,
by doing some simple tests first…
6. Tests Done to reveal Latent
Squint
You must Prevent Fusion to reveal it!
How?!
By Covering One Eye.. This is called
“Alternate Cover Test”

“Madox Wing” can also be used.
