Treatment Summary

Tropicamide is a medication used to dilate the pupil of the eye and temporarily paralyze the focusing muscles. It is used to help doctors or eye surgeons examine or treat the eye. Tropicamide can also be taken orally to help reduce excessive saliva in people with Parkinson's Disease.

Effectiveness

How Tropicamide Affects Patients

Tropicamide is a drug that helps with dilation of the pupil and relaxation of the eye muscles. It takes 10-15 minutes to start working, and its effects can last up to 24 hours. It can also raise the pressure inside the eye, but this is usually not associated with serious side effects. Tropicamide has been used to reduce symptoms of excessive saliva (sialorrhea) in people with Parkinson's Disease, and can be used to reduce tremulous jaw movements in rodent models.

How Tropicamide works in the body

Tropicamide is a drug that relaxes the muscles that control the pupil size and lens shape of the eye. It works by blocking muscarinic receptors in the eye, which are responsible for pupil constriction and accommodation. It also blocks salivary gland receptors, reducing saliva production. By blocking these receptors, tropicamide helps to reduce sialorrhea.

Tropicamide Toxicity & Overdose Risk

The lowest toxic dose of tropicamide in rats is 865mg/kg when taken orally, and 1210mg/kg when taken intraperitoneally. In mice, the lowest toxic dose is 565mg/kg when taken orally, and 695mg/kg when taken intraperitoneally. In the case of an overdose, side effects such as rapid heartbeat, confusion, muscle stiffness, and breathing problems have been observed in both adults and children.

Tropicamide Reviews: What are patients saying about Tropicamide?

Tropicamide for Dilated Pupil

This is an excellent way to dilate your pupils with no other known side effects. It's both safe and effective, which makes it a great option overall.

Patient Review

Tropicamide for Dilated Pupil

These eye drops caused an intense burning sensation that made it difficult to open my eyes for some time. Even days later, my eyes were still sensitive to light. This has never happened before during my annual eye examinations, so I'm not sure if the medicine has changed or if it was just too strong this time around.

Patient Review

2/19/2022

Tropicamide for Dilated Pupil

After using this medication, my eyes stayed dilated for six to eight hours. This was a problem because it made bright light intolerable. Additionally, my eyes were sensitive to light for two to three days following useage; it seems like the drug's effects and side-effects last too long.

Patient Q&A Section about tropicamide

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

How does tropicamide work in the eye?

"Tropicamide is a non-selective muscarinic antagonist that prevents the pupil from constricting by binding to muscarinic receptors, as well as prevents the eye from focusing by blocking the muscarinic receptors of the ciliary body."

Answered by AI

Is tropicamide eye drops safe?

"Tropicamide ophthalmic may cause blurred vision or make your eyes very sensitive to light. Be careful if driving or doing anything that requires clear vision. This effect may last up to 24 hours. Protect eyes from bright light while pupils are dilated."

Answered by AI

What type of drug is tropicamide?

"Tropicamide is a medication that is used to widen the pupil in preparation for certain eye examinations. It is an anticholinergic that works by relaxing the eye muscles."

Answered by AI

What is tropicamide used for?

"Tropicamide is used in order to increase the size of the pupil so that the doctor can clearly see the back of the eye. It is commonly used before examinations such as cycloplegic refraction and examination of the fundus of the eye. In some cases, tropicamide may also be used before and after eye surgery."

LLM-Based Education for Cataract Surgery

All Sexes
Palo Alto, CA

Patients with cataracts disease need to choose what type of artificial lens will go into their eye prior to surgery date. Some lenses are standard and are usually covered by insurance. Other "premium" lenses have various benefits such as reducing the need for glasses but usually require out-of-pocket costs. The combined busy outpatient clinic and complexity of artificial lens choices in the ever-changing world of cataract surgery tends to lead patients confused about their available lens options. There is an abundance of educational material present in premium lenses, however these are limited by accessibility and are standardized at single educational levels. Therefore in the present study, we want to test whether giving patients a short LLM powered AI-guided explanation from Custom GPT from OpenAI of lens options prior to their consultation with their doctor can improve visit efficiency, physician explanation and patient understanding of lens options. We will compare two groups: standard of care versus standard of care plus AI education. The LLM in this study is intended to provide supplemental information about premium intraocular lens(IOLs) options to study participants, and is no means supposed to replace a health care professional in the diagnosis, cure, treatment, and/or mitigation of disease. Study is analogous to giving a verified health pamphlet to a patient for them to view and learn different IOL options, in other words, facilitating patient understanding of their options. The LLM will be trained by several health care professionals and MD specialists to provide sufficient instructions. Sources will include verified online resources and MD information. The investigators hope to learn if a large language model-based educational tool can improve visit efficiency, physician explanation and patient understanding of intraocular lens options. New knowledge of this study could guide how cataract counseling is delivered in the future and may help clinics spend more time on individualized questions instead of repeating generic information.

Vision Centers for Eye Care

Any Age
All Sexes
San Francisco, CA

The goal of this clinical trial is to evaluate the effect of vision centers on access to eye care and eye health outcomes in South Asia. The main questions it aims to answer are: 1. Do vision centers increase visits to eyecare centers? 2. Do vision centers increase spectacle ownership and wearing? 3. Do vision centers improve visual acuity of the population? Researchers will compare outcomes in communities randomized to have a vision center is established with communities randomized to delay establishment of a vision center. Outcomes will be assessed through population-based surveys at baseline and after two years as well as through hospital records collected throughout the study period.
