Hey, I wanted to delve into my 1mm diameter constricted pupils from last night to 12 pm this afternoon. It was caused a stimulant, though. Concerta (methylphenidate) to be exact. Im not a crazy druggie or anything, but I do realize that I took 216 mg of concerta xr all within 20 minutes, and it caused slight paranioa, intense heart beat, and unbalanced depth perception (because if i looked at my laptop, it seemed like it kept shifting). Just wanted to help out.
P.S. I was planning on taking 150 mg which is double my dose, and i wanted to seewhat would happen. I failed at keeping track though XD. NOT DOING THAT AGAIN!

Just found your site today while resting after a gastro- bug bite. Am in process of renewing my teaching certification for EMT after several years of just practicing medicine as a PA. I am very impressed with what I have seen of your content, and plan to make your site required reading for future students. The Pinpoint Pupil article is a classic in that it puts all the emphasis on constriction without mentioning dilation to any degree. As a result the confusion that often occurs to a student is avoided, since the issue of dilation can then be implanted in a separate class or article. Thank you for your perspective on 3 minutes, 3hrs, 3 weeks. That is a classic also, and one that must be impressed from the very first class to all potential EMS students.
Keep them coming

As I found out last night, theres one more thing that can cause pinpoint pupils: SKUNK SPRAY. One of my dogs got a load into her eye and that eye constricted to pinpoint within a couple minutes. I did the usual skunk wash (Dawn dish detergent, baking soda and hydrogen peroxide) around her eye, then tried irrigating her eye with water, but that was difficult. As it was evening, she bedded down for the night and about an hour after the incident her pupil started growing slightly. By morning it was normal and her eye looked fine. She had no irritation or watering in the eye either.
Now – what skunk spray contains to do that is beyond me, however it may have evolved as part of the defense mechanism as when pupils constrict – you cannot see and the skunk escapes the predator.

thanks mate, you learn something new everyday. i never realized opiate could cause pinpoint pupils- rather, i always thought they dilated them like most other drugs. again, thanks

I am a TLE pt w/long post-ictal times where I can hear, feel, but cannot talk, move, respond. I have, right now, a lump and bruise from repeated sternal rubs that I felt but was unable to respond to. Vitamin A – ammonia under or UP the nose does not work and with COPD, it is very disturbing. My eyes are the first to “come back”, speach comes back as “moaning”, legs/arms can take 12 or more hrs to come back. Full, normal speach, can take up to 24 hrs. THIS IS REAL – documented. Laughing, talking psych, etc. may anger me, but I cannot tell you that – because I cannot talk. I take MANY epileptic meds and no psych meds and live a facility because of the epilepsy, COPD, CH, PVD, etc. 2x I had “grand-mal” and “coma” from low potassium and once from low magnesium. My seizures began when I was 18 mos old – same as now – staring, stiffening, going limp and unresponsive, then poof – back to reality with amnesia for the event. PLEASE TRAIN YOUR EMT’S FOR POST-ICTAL/ICTYL STAGES and the various TYPES of epilepsy. My vitals are usually normal – just unresponsive due to epilepsy – NOT psych. Thank you. God bless you.
