Fixed and dilated pupils in comatose patients are well known to be related to a poor progno-sis, especially when present bilaterally.1-5 If not caused by local trauma or drug action, this symptom indicates injury or compression of the third cranial nerve and the upper brain stem, mainly caused by an extending intracra-. Studies have shown that various medical conditions and usage of certain drugs cause pinpoint pupils. So what causes pinpoint pupils, here we discuss some reasons. Narcotic Medications: Most narcotic pain medications have the presence of opioids in them. Morphine which is a form of opioid is commonly present is pain relief medicines Doctors sometimes refer to more pronounced mydriasis, when the pupils are fixed and dilated, as blown pupil.This condition can be a symptom of an injury to the brain from physical trauma or a stroke.The opposite of mydriasis is called miosis and is when the iris constricts to cause very small or pinpoint pupils

Fixed dilated pupil: dilated, unresponsive pupil, e.g. due to closed-angle glaucoma; Hutchinson pupil: pupillary abnormalities that lead to a fixed dilated pupil in 3 stages as a result of increased intracranial pressure (typically uncal herniation)

Checking the Pupils During Patient Assessment An essential part of an EMT's patient assessment is to check for a pupillary response; mainly that the pupils are equal and reactive to light.The patient's pupil diameter and how they respond to light will help determine the status of the brain and how it is perfusing and oxygenating, as well as its overall condition What kind of drugs cause pinpoint pupils? Examples are methadone, morphine, and heroin. These drugs stimulate the parasympathetic nervous system causing abnormal miosis. Some types of morphine are actually used for pain control such as morphine and codeine. As a matter of fact, they are very effective in the treatment of intense pain

Normal pupils are 2 to 4 millimeters in bright light and 4 to 8 millimeters in the dark. Your doctor can measure your pupils in both eyes to see how well they shrink and grow Drug Use . Drugs can expand or shrink the eye muscles, causing mydriasis. Substances such as cocaine increase serotonin level, which can lead to pupil dilatation. LSD has a direct effect on serotonin receptors in the brain, which can also cause mydriasis. Other drugs that have a similar side effect are crystal methamphetamine and ecstasy The possible causes of unilateral dilated fixed pupil (not responding/reacting to light both directly and indirectly) are multiple and include lesions in the mid-brain, ciliary ganglion, or short ciliary nerve pathology (including Adies pupil, orbital trauma), lesion of the third cranial nerve, and pathology of the iris (i.e., blunt trauma. A score of 2 means both pupils are non-reactive to light; a score of 1 means one pupil is non-reactive; and a score of 0 means neither pupil is non-reactive. What does it mean if pupils are fixed?

The science behind drugs causing dilated pupils. Your pupils are the black dots in the center of your eyes that change in size in order to regulate the amount of light that enters. This light regulation is crucial to things like normal vision and focus. The size of your pupil is directed by the colored portion of your eye called the iris Digre KB.

When encountering this situation, the first step is to establish whether the anisocoria changes with ambient lighting Pharmacologic dilation of the pupil is one of the myriad explanations for unilateral or bilateral pupillary dilation. It is typically characterized by poor or no pupillary constriction to light or near stimuli.
