  2. Mydriasis - Wikipedia

    en.wikipedia.org/wiki/Mydriasis

    Mydriasis is frequently induced by drugs for certain ophthalmic examinations and procedures, particularly those requiring visual access to the retina. Fixed, unilateral mydriasis could be a symptom of raised intracranial pressure. The opposite, constriction of the pupil, is referred to as miosis. Both mydriasis and miosis can be physiological.

    Miosis caused by high doses of opiates. The person also shows ptosis of both eyelids and an inattentive look at the camera, a sign of altered level of consciousness caused by the sedative effect of the drug.

  4. Pupillary response - Wikipedia

    en.wikipedia.org/wiki/Pupillary_response

    Dilation and constriction of the pupil. Pupillary response is a physiological response that varies the size of the pupil, via the optic and oculomotor cranial nerve.. A constriction response (), [1] is the narrowing of the pupil, which may be caused by scleral buckles or drugs such as opiates/opioids or anti-hypertension medications.

  5. Cycloplegia - Wikipedia

    en.wikipedia.org/wiki/Cycloplegia

    All cycloplegics are also mydriatic (pupil dilating) agents and are used as such during eye examination to better visualize the retina. When cycloplegic drugs are used as a mydriatic to dilate the pupil, the pupil in the normal eye regains its function when the drugs are metabolized or carried away.

  6. Pilocarpine - Wikipedia

    Pilocarpine has been known to cause excessive salivation, sweating, bronchial mucus secretion, bronchospasm, bradycardia, vasodilation, and diarrhea. Eye drops can result in brow ache and chronic use in miosis. It can also cause temporary blurred vision or darkness of vision, temporary shortsightedness, hyphema and retinal detachment.

  8. Tropicamide - Wikipedia

    en.wikipedia.org/wiki/Tropicamide

    Anisocoria caused by tropicamide instilled into the subject's right eye only. Tropicamide is an antimuscarinic drug that produces short acting mydriasis (dilation of the pupil) and cycloplegia [7] when applied as eye drops. It is used to allow better examination of the lens, vitreous humor, and retina.

  9. Atropine - Wikipedia

    en.wikipedia.org/wiki/Atropine

    Topical atropine is used as a cycloplegic, to temporarily paralyze the accommodation reflex, and as a mydriatic, to dilate the pupils. [15] Atropine degrades slowly, typically wearing off in 7 to 14 days, so it is generally used as a therapeutic mydriatic, whereas tropicamide (a shorter-acting cholinergic antagonist) or phenylephrine (an α-adrenergic agonist) is preferred as an aid to ...
