Will my retinas be damaged by mydriasis?

No: Mydriasis, or dilated pupils, can be caused by eyedrops administered at the doctor's office or as the result of disease or injury. Although the pupil helps to control the amount of light entering the eye, it affords little help in protecting the eye from the light. Sunglasses will help reduce the intensity of the light and will add another layer of protection against uv damage. ...Read more

A few possibilities: Traumatic mydriasis, or perminent dilation of the eye from an injury, is not a curable condition. It is, however, treatable. Usually drops that shrink the pupil do not work on this. A colored contact lens can help with the sensitivity to light. Surgery can be done to shrink the pupil. See your ophthalmologist to review your options. ...Read more

Does mydriasis damage inner eyes?

Does mydriasis damage inner eyes?

No: Mydriasis means the pupil is dilated. It is a normal function of the pupil. Dilating eye drops will cause extreme mydriasis for a short time without any lasting side effects.

The retina is exposed to more light, but this doesn't generally cause damage, unless it is intense and sustained, which is painful. ...Read more

Hi, I'm looking for an expert opinion on the mechanism of ETOH on CNIII (oculomotor nerve). Many sources denote mydriasis to be present over miosis.

Hi, I'm looking for an expert opinion on the mechanism of ETOH on CNIII (oculomotor nerve). Many sources denote mydriasis to be present over miosis.

My comments: Am somewhat surprised you would focus on cranial nerve III---have you developed a problem with that nerve? The acute effect of alcohol is to suppress most brain functions, but it is not specific to autonomic fibers. If while drinking your emotions become excited, your pupils will dilate, a bit, but doubt it would be profound. Lastly, if you have a problem, schedule Concierge visit. ...Read more

Can bilateral mydriasis indicate increased intracranial pressure? Both my pupils react evenly, but my doctor was still surprised at this.

Mydriasis: Or pupil dilation is quite common in younger people. They tend to have naturally larger pupils. As long as they are equal and both react well, then this is totally normal. On the other hand, an increase in intracranial pressure can cause one or both pupils to dilate but typically they don't react well in this situation. ...Read more

Eye traumaic pupilary mydriasis is tht curable. Eye had blunt truama one month ago with a tennis ball?

May improve: Mydriasis from trauma may spontaneously improve over a six month period but usually is stable after that. You can ask your ophthalmologist to prescribe Pilocarpine which is a pupillary constrictor which might encourage the pupil to narrow. If the pupil is widely dilated, there is an intraocular implant of an artificial pupil which might help and colored contact lenses might also be used. ...Read more

What causes dilated pupils and racing pulse?

Adrenaline surge...: Adrenaline is the principal mediator of the "fight or flight" response. This prepares your body for immediate action. Pupils dilate to increase light transmission, heart rate and blood pressure go up and blood is shunted away from other organs to the skeletal muscles. If this occurring in the absence of a stimulus, it is likely due to hypoglycemia or low blood sugar. Check for Insulin resistance. ...Read more
