Help Regarding My Eye Sight

Hello, I am 17 years old student from Nepal. While my dream is to be a pilot, some issues regarding my eyesight always puts me in doubt whether I can pursue to pass Class-1 Medical examination test or not. From what I know, i’ve intermittent exotropia in my eyes due to which it tends to squint or drift outwards. My left eyes vision is a bit blurry and I have hard times to focus. With that, I do get double visions too.

Yet, I’m not giving up. I go on therapies in hospital every week to improve vision and have been consistently doing brock string in home to improve it too. As a 17 years old still chasing for my dreams, its really hard for me to be completely sured whether I can pass Medical Exams for pilots or not. I really will appreciate any help or guidances from the experts in this website. I just found out about this websites and wanted to get help from people who have some ideas related with it. Even if I have to undergo surgery to fix my vision, I’m well determined to take the action as long as it makes me fit for a future Pilot.

Here are some details about my eye problems, given by my doctor:Cover Test:

• Distance (D): 12∆ XT / Alternating XT

• Your eyes deviate 12 prism diopters outward at distance.

• Near (N): Exo D/C (likely Exo Deviation/Control)

• You also have outward deviation at near, but it’s likely controlled better.



PBCT (Prism Bar Cover Test):

• Unaided Distance: 16–18∆ XT

• Unaided Near: 10∆ XT

• Confirms divergence excess exotropia — larger deviation at distance than near.


Accommodation & Vergence (Eye Teaming) Function:



NPC (Near Point of Convergence):

• 12 cm (OS) — Slightly poor convergence ability (ideally should be less than 10 cm).



Fusional Vergence Amplitudes (FVA):

• NFV (Negative Fusional Vergence) and PFV (Positive Fusional Vergence) are both reduced at distance and near.

• Indicates poor ability of your eyes to work together effectively, both for crossing (convergence) and separating (divergence).

Vergence Facility Test:

• With 12∆ BO (base-out prism) and 3 Base-In prism:

You had trouble clearing and sustaining fusion — consistent with exotropia and vergence insufficiency.



Management:

• Office Vision Therapy (VT)

• Home Vision Therapy (HVT)

• Exercises recommended:

• Brock String: 15 minutes daily

• Lens Flippers or Similar Vergence/Accommodation Workouts
