Firstly, I've posted this in the ADD section as I am looking for the most accurate scientific answer I can get. Although I'm not yet myself knowledgeable enough to know of the biochemistry and neuroscience behind the answers I am looking for, I am extremely interested in discovering them and learning to understand them. This curiosity stems from both the fact that I seem to get more pronounced visual side-effects from particular drugs than others and the fact that I have a developing interest in biochem and neuroscience and hope to be studying such material at University in some capacity very soon.
My first question is basically, what is the biology/chemistry behind the visual effects that are caused by certain drugs, and why can it be more pronounced in certain indivudals.
The major effect I'm referring to is diplopia, or double vision. Or at least I think this is what it is. It is blurry vision, sometimes perceived as double vision, which can be almost entirely overcome by closing or covering one eye. This happens to me on nearly every recreational drug I take including MDMA, and all opiates and benzodiazapines when taken in high enough doses. The blurry vision, and the 'covering one eye fix', seems to be the same with all categories of drugs despite the fact that MDMA causes significant dilation of the pupil, whilst opiates cause constriction of the pupils leading to 'pinpoint pupils'. I don't understand the correlation in visual impairment despite the effects on the pupils being basically polar opposites in the cases of opiates or benzos.
One more note on the visual side-effects caused by MDMA, especially at high doses, is the sensitivity to light caused by the drug.When I take enough of this substance I cannot read any sort of text at all, sometimes even large text. Text on a computer or phone screen is even harder to read as the backklight completely dominates my vision. I can logically assume that the dilation caused by the MDMA leads to excessive light being allowed to enter the back of the eye, which leads to light becoming more pronounced, which therefore overwhelms the 'dimmer' light entering the back of the eye, which leads to bright white light being so much more prevalent and hence the inability to distinguish dimmer text.
So I guess my second question is are my amateur logical deductions correct? And if so could anyone please neaten them up, and introduce me to any vocabulary that I could have used in place of other terms. And can anyone give me a more advanced explaination of hte phenomenon, or at least point me in the right direction to discover it myself.
Finally, why do I get this particular visual impairment from MDMA more than anyone else? Despite taking the same dose, or even sometimes less, than others I'm always much more useless when it comes to reading any sort of text when under the influence of MDMA? What is it in my biochemistry that leads me to be particularly susceptible to this?
Thanks (and again, if this is not advanced enough for ADD please at least throw me some terms/mechanisms/ect to look up for myself rather than just dismiss/ignore me)
