Pupil dilation, or mydriasis, can be triggered by a wide array of factors, from changes in light to emotional responses and, notably, exposure to certain drugs. The question of 'what drug causes eyes to get big' points to a specific physiological response where substances interfere with the nervous system's control over the eye's muscles. This article explores the pharmacological mechanisms behind drug-induced mydriasis and lists common culprits.

According to the Centers for Disease Control and Prevention, over 13% of American adults use antidepressants, with Selective Serotonin Reuptake Inhibitors (SSRIs) being the most commonly prescribed type. For many taking this medication, a notable side effect is the potential for pupil dilation, raising the question: Do SSRIs change your pupils?.

Following some ophthalmologic procedures, such as cataract surgery, a common prescription is homatropine eye drops. What is homatropine after surgery? It is an anticholinergic medication used to treat inflammation and relax eye muscles, which is crucial for a comfortable and effective recovery.

Atropine is an essential medicine derived from the deadly nightshade plant [1.6.3]. How long does it take atropine to wear off? The answer varies significantly, from hours for an injection to up to two weeks for eye drops [1.3.1, 1.2.7].

While systemic atropine was found to increase intraocular pressure (IOP) by more than 6 mm Hg in 8% of normal adults, its effect, particularly in topical form, is highly nuanced [1.4.2]. The question 'Does atropine increase ocular pressure?' depends significantly on patient-specific factors.

Systemic atropine may increase intraocular pressure (IOP) by more than 6 mmHg in about 8% of normal adults [1.3.2]. This article explains the mechanisms behind this effect, detailing how does atropine affect eye pressure, particularly in individuals with different types of glaucoma.

Used for over a century to treat glaucoma, pilocarpine is a well-established ophthalmic medication [1.2.2]. The central question for many users is: **do pilocarpine eye drops constrict or dilate eyes?** The answer lies in its specific pharmacological action on the eye's muscles.

In ophthalmology, atropine is the most potent cycloplegic agent available, widely known for its ability to dilate pupils. The question, 'Can atropine eye drops cause pupil dilation?', is fundamental to understanding its medical use for everything from routine eye exams to managing specific eye conditions like amblyopia.

Tropicamide's effect typically lasts for 4 to 8 hours for most individuals, though full recovery can sometimes take up to 24 hours, influenced by factors like iris pigmentation. This guide explores the details of how long tropicamide dilate eyes and what to expect during the recovery period after an eye exam or procedure.

Cyclopentolate has a relatively short duration of action compared to more potent alternatives like atropine and is widely considered the standard of care for pediatric cycloplegic examinations. This anticholinergic eye drop is primarily used to dilate pupils (mydriasis) and paralyze the eye's focusing muscles (cycloplegia), enabling a thorough eye examination.
