Exophoria and Exotropia and Strabismus- Aren't they the same?!

Hello to you all!,

Hope you are all well...

Exophoria and Exotropia and Strabismus.

Outlined above are three conditions and if I understand correctly, they have the same symptoms...whereby the eye just deviates from a normal position outwards while the other eye remains unchanged.

But they are three different conditions? I don't get why they are all different? Why are they not under one name. They both have the same outcome (deviation of the eyeball).

The CAA Class One Medical Requirements are as follows;

"You must have normal fields of vision.
You must not suffer from double vision.
Any degree of heterophoria (eye muscle imbalance) in excess of:
8Δ exo, 10Δ eso or 2Δ hyperphoria - measured at 6 m
12Δ exo, 8Δ eso or 1Δ hyperphoria - measured at 33 cm
will require further evaluation by an eye specialist at Gatwick.

Now I don't think the are talking about strabismus, but it is the same essentially right?

What is the difference between these disorders? I'm trying to figure out which one I have (both my eyes deviate sometimes...but I can control it but sometimes it'll deviate by itself..). I also have myopia

But more importantly what does this mean for an individual that wants to be a commercial airline pilot? Is there not surgery available for these disorders? Can they be fixed or do we write off a whole career?

Anyway's guys watch this space, I'm going to go to Vision Express tomorrow to discuss this with an Optician to see what he says (I'll take the class 1 medical vision requirements with me and see what they say).

If anyone can answer this question I (and a many others) would greatly appreciate it!

Speak soon guys, I'll keep ya'll updated as to what the Optician says!

Captain Bolt!

N.B. Some may say that Lazy Eye is also a disorder in which an eye deviates outwards, however I found out today that it is a completely different disorder...! Learn something new everyday lol...!
