Retinal tear/detachment after acceleration in car

[sidlennon]

Hello, I am facing terrible anxiety over something that just happened. I had a small retinal tear 7 years back and was treated with laser.

Today, a friend accelerated his Tesla car very fast, from 0-100 km/hr in around 5 seconds. I am very scared that it may have moved the vitreous and caused retinal tear or could lead to detachment.

Can someone please help me here? I am very scared and anxious.

I can't comment on the medical impacts of that g force, but on a quick check 0-100 km/hr is not really a very high g force at about 0.5 G. You likely experience a higher G force by just jumping down off a small one step stool. Braking force in a car or or landing in a passenger jet is also likely higher and approaching 1 G. You might want to be more worried about going on a roller coaster which can hit 5-6 G's.

Correction: "0-100 km/hr in 5 seconds"

Thanks Ron.
I fly a lot and have been doing that for many years.

So are you saying that if braking in passenger jet with a higher G-force doesn't harm, why would this?

I can see alright. But worried, because there is a comment asking the driver never to do it next time.

Just worried if there is manifestation later.

Roughly according to theory you can't exceed 1 G in acceleration or the wheels spin. Same when stopping even when you lock the brakes. A passenger jet can exceed 1 G in braking as they can reverse the thrust on the engines in addition to using the brakes.

At this point it would be good to work on your OCD.

I am sorry about the OCD, but since you said to ask the driver not to floor it next time, I got more worried. Apologies, but it is a miserable state to relive the moment.

I have given you all the imporatnt information. You might consider going to one of the anxiety forums for solace. I will have no more to say

1 if you ride with the driver tell him/her not to 'floor it' and explain your eye  condition  2. The risk on this single event is extremely low

[sidlennon]

Thank you sir. So are you saying the chances are low, like 0.1 %?

So you mean if this were not a single event, it could cause issues?
Many thanks

[sidlennon]

Is it because you think if this is repeated, it could cause retinal tear?

[John C Hagan III, MD, FACS, FAAO]

Yes I have been in a Tesla when the driver stomped it. Never felt anythibng like it and I've driven Porsche, BMS and Corvette.  Next time tell the driiver to take it easy. I have never seen a case in the ophthalmology literature of RD caused by rapid car acceleration.  As long as you don't have the cardinal symptoms of RD: new floaters, flashes of light, loss of field of vision, I think you can dial back the worry and anxiety.

[sidlennon]

Thank you sir. But you mentioned to ask the driver to take it easy.

Does that mean you think it could cause a RD or a year?

Is there a risk for me? Or was that just for general safety? Apologies for the OCD around it

[sidlennon]

Also is it possible that the symptoms manifest after some time due to this car adventure?
