Hyperphoria and my Initial Class 1 Medical

Hey all, this is my first post on PPRuNe after being a lurker with no account for nearly half a year.

I had my initial class 1 medical examination today and it did not go as well as I was hoping. We went through my medical history and I had anemia, iron deficiency and hemoglobin deficiency as a child. These were between the ages of 2 and 8, so 6 years of my life. In the space of 11 years, there has been no sign of anemia and the deficiencies. However, the AME would like me to get a full blood test with the analysis and I need to see a specialist regarding a hemoglobin test. However, this is currently looking positive as there were no signs of the medical problems during my blood test performed on the day.

Now the real problem is, although I wear glasses, and I know that since my first optician's eye test that my eyesight is and has been greater than 20/20, I have a slight issue with my hyperphoria. When the optometrist was performing my eye test for the Class 1 Medical, my hyperphoria (vertical eye separation) was 4.0 diopters and the maximum to pass is 2.0 diopters, so essentially I didn't pass the eye test, to say this is really disappointing is an understatement as I would've never expected this to be a problem. I spoke to the optometrist regarding this and I can appeal this, and they recommended I do.

Then I went back to speak to the AME, my next step is to complete the hemoglobin and blood test and send the results to the AME, and if those come back as a pass, I can make the appeal for my class 1 medical. Now I have never had double vision and I notice no difference between both eyes regarding the vertical difference. I don't want to give up on my goal to become a commercial airline pilot, however, I don't want to go through the whole training process and the expense to have a restriction on my class 1 medical that airlines won't accept. When I was speaking to the AME the talk about settling in for a class 2 did come up, but I don't want to throw in the towel, I was told there is a possibility of still getting a class 1 medical, it may require more tests, there was even talk on a possible option where I could continue flying and if I feel comfortable and the CAA agree (I'm sure there is more to it that I don't know as of yet) I may still be issued my class 1. I currently have 8 flying hours and the money I've spent already is not a issue as I've enjoyed every second of it.

I'm currently in a tricky situation, I searched up a little about hyperphoria and the CAA Class 1 but there's not much to it regarding a post on PPRuNe from 2005 and this from the CAA Guidance, where the 4 dioptres are at 6 meters.

h) HeterophoriaApplicants with a heterophoria (imbalance of the ocular muscles) exceeding:
(1) At 6
metres:
2.0 prism dioptres in hyperphoria,
10.0 prism dioptres in esophoria,
8.0 prism dioptres in exophoria;
and
(2) At 33
centimetres:
1.0 prism dioptre in hyperphoria,
8.0 prism dioptres in esophoria,
12.0 prism dioptres in exophoria
should be assessed as unfit. The applicant should be reviewed by an ophthalmologist and if the fusional reserves are sufficient to prevent asthenopia and diplopia a fit assessment may be considered.

Would I have a chance of receiving my class 1 medical, or am I just wasting my time?

Thanks,
Chak.

@Chak I can't give any information regarding the condition, but I'm sure another Ppruner or even an AME will respond soon on that. What I can say is that, don't give up hope just yet. I've read loads of threads on here and around the web of people failing the initial medical due to exceeding one of the regulations only to appeal and be signed off as fit to fly. I believe the guidelines say that some discretion can be made on a case-by-case basis by the CAA upon appeal. They may likely look at your situation, and with further tests, deem you fit too.You're really not going to know until you proceed with the appeal, so don't loose hope yet. I feel for you when reading this as I was just as nervous for my vision in my initial last month. Good luck and keep us updated!

@CJS12 Thank you for your advice, I really appreciate it. I'm trying not to lose hope yet, I'm doing better than I was yesterday and have already started to make a progression on the report the AME requires and booking in a blood test. Once again, thank you! Once I am ready for the appeal I will post an update.

Hi Guys, I recently did the Ishihara and Lantern test and failed both miserably. Booked in to do the CAD test in Heathrow next week.

Has anyone done the CAD test recently at Heathrow? Or anyone failed the Ishihara and Lantern test but passed the CAD?

Cheers!

Hey i was in the same situation as yours, failed the medical due to the phoria. I have 3 diopters of hyperphoria the limit is 2, and on top of that i have 35 diopters of exophoria at near (the limit for near is 12) and 20 at distance (the limit for distance is 8). So as you can see im wayyyyyy out the limits, but i appealed to the CAA for a secondary review. After 6 months i got a letter from the CAA stating that im fit to fly because i have a strong prism fusion range so i dont have double vision (wich is the risk), the fresh class 1 medical was in the same letter btw.

So if you dont have double vision my advice is that you should elaborate your case well and than appeal to the CAA. They are flexible with phorias if you dont have double vision.

Good news is that my blood test came back normal, no abnormalities in my blood, no traces of anemia or iron deficiency. The report is ready to be picked up tomorrow and I will be sending that to the AME as soon as possible. On track so far.

Hey Abbas,

This was a reply I was hoping for, someone who was in a near enough exact position as me, alongside making an appeal/review and everything working out fine in the end. 6 months is a long time to wait for the reply, but the wait was definitely worth the good news. I'm hoping to send the required reports which were asked by my AME, and hopefully, we get the secondary review process started.

Thanks.

Glad that my response was helpful. As for me i was in even worse condition than yours, my AME told me that according to him gaining a class 1 was impossible for me and the best thing to do was changing career. I was destroyed that day but ive promised to my self that i will not give up, because becoming an airline pilot was my dream since childhood. And yess, the day when i recieved the medical that day i realized that nothing is impossible, if you work hard for something, you will achieve it.

Best of luck with the appeal.

Hello PPRuNe, quick query as the only information i can find on this is Part Med.

With regards to the following ...

AMC1 MED.B.070 d,(5)
  1. If the refractive error is +3.0 to +5.0 or Ė3.0 to Ė6.0 dioptres, there is astigmatism or anisometropia of more than 2 dioptres but less than 3 dioptres, a review should be undertaken 5 yearly by an eye specialist.
I've had my Class 1 issued to me 3 years ago by the UK CAA, I have recently transferred it over to the IAA... my only limitation was a VDL restriction however when the IAA reviewed it they decided to apply the RXO restriction as well.

My astigmatism is 2.0 dioptres, surely according the wording above I shouldn't have the RXO limitation?

Very interesting talk about [email protected] eye surgery at White Waltham club last night. Particularly a technique called 'blended vision' whereby you have one eye set to 6/6 distance vision, but a bit of short sight in the other to remove the need for reading glasses in middle age. The argument was that it's good for pilots because you don't have the intermediate distance issue of bifocals or the problem with seeing instruments above the windscreen. One professional pilot there who is also an AME has been given 6/9 uncorrected distance vision in one eye and 6/5 in the other, but can also read small print with her 'short' eye without correction so has an unrestricted medical in her late 50s. All sounded quite encouraging.

Class I Medical Failure

In 1998 I completed so much flight training and then I failed my class I medical.

I understand now that the medical standard for eyesight has been relaxed a little.

The CAA advocate safety but how can it not be OK one year but then OK the next?

Just curious

Cool Refractive Lens Exchange

I recently had an eye exam with one of the [email protected] outfits who said they could restore glasses-free sight by refractive lens exchange - same procedure as for cataracts but inserting a multifocal lens. I checked EASA FCL-Med and the procedure is completely forbidden. As a retired pilot still practising as a part-time instructor, it's not the end of the world for me but it might be relevant to younger colleagues. I know that our now defunct CAA Medical Department was notoriously conservative with 'new' eye stuff such as contact lenses and varifocals but it does seem to me that allowing a clear lens for cataracts but not a clever one for sight correction is slightly bizarre. I'd be interested to know if anyone else has been down this route.
