For example, if constricted pupils are caused by drug use, the treatment may involve rehabilitation and counseling to address the addiction. If constricted pupils are caused by neurological disorders, the treatment may involve medications, physical therapy, or other interventions to manage the condition. Constricted pupils can also be a sign of neurological conditions such as Horner syndrome, a rare disorder that affects the nerves in the face and eyes. In addition, certain medications, such as pilocarpine used to treat glaucoma, can cause constricted pupils as a side effect.
It can also happen if you take other medications designed to constrict your pupils. Typically, your pupils get bigger or smaller when light enters your eyes. If you have miosis, your pupils stay small even if the light changes. However, since miosis may result from certain diseases and conditions, accompanying symptoms may vary.

Unusually small pupils may be caused by a number of factors, including drug use, injury or an underlying health issue. Medications, trauma, and medical conditions can lead to abnormally small pupils (miosis). In miosis, the pupil is smaller than it should be, even in darkened conditions when it would typically expand (dilate). Variations in lighting conditions are the most common reason for a change in pupil size.
- If the pupil doesn’t vary in size in response to changes in lighting and gaze, there might be something wrong.
- If too much light hits the retina, miosis will occur, and the pupil will contract.
- He strongly believes in the transformative power of ophthalmic education through research to inform and educate those seeking knowledge in eye health.
- This could include medications aimed at alleviating symptoms or therapies designed to improve overall neurological function.
- Argyll Robertson (AR) pupil is a condition causing small pupils and light–near dissociation.
What is Horner’s Syndrome?
Corticosteroids and other topical ointments are eye miosis constricted pupils: causes treatment typical treatments for anterior uveitis. Additional steps may be necessary if the cause is determined to be an underlying disease. Accompanying symptoms may offer a clue about what’s causing the problem. Other than lighting, pupils can change size in reaction to other stimuli. For instance, your pupils might get bigger when you’re excited or on heightened alert.
- In miosis, the diameter of the pupil is less than 2 millimeters (mm), or just over 1/16th of an inch.
- Anterior uveitis can cause the pupil to become smaller and atypical in shape.
- Pinpoint pupils (myosis or miosis) is the condition when your pupils are unusually small.
This is especially important if you have had an eye or head injury or symptoms of a stroke. Furthermore, certain medical conditions can lead to dilated pupils. One such condition is anisocoria, which is characterized by unequal pupil sizes. Anisocoria can be a sign of a serious medical problem, such as a brain tumor or nerve damage.

Photochromic lenses, used indoors and outdoors, darken to protect your eyes from light changes. Other causes include surgical trauma, neuroblastoma, brainstem lesions (such as vascular malformations, glioma and demyelination) and carotid artery thrombosis. The first order (central) neuron descends caudally from the hypothalamus to the first synapse in the cervical spinal cord (C8-T2 level-also called the ciliospinal center of Budge).
In this blog post, we explore what anisocoria is, its causes and treatments, and how you can protect your vision if you have it. In addition, prolonged use of tobacco products, including liquid vapes, can cause reduced retinal activity and poor eyesight. Intracerebral hemorrhage may cause severe headache, nausea, and vomiting, and may be followed by loss of consciousness. People with a history of retinal detachment or those with significant risk factors for it may be advised against using strong miotics.
When should you seek help?
Opioid drugs, for example, are known to cause miosis as a side effect. Additionally, the use of certain prescription eye drops, such as those used to treat glaucoma, can also lead to constricted pupils as a result of their intended pharmacological effects. The use of eye drops to intentionally constrict the pupils, a process medically known as miosis, is a targeted therapeutic approach in eye care.
Certain medications, like pilocarpine, can lead to a statistically significant deterioration in visual acuity, particularly in individuals with cataracts. This deterioration may influence overall visual results and requires careful observation of eye size and function during treatment. Diagnosis typically involves a comprehensive eye examination, neurological assessment, and possibly imaging studies. Treatment depends on the underlying cause and may include medication adjustments, managing neurological conditions, or addressing inflammatory issues affecting the eye. Blown pupils are fixed, dilated pupils that do not react to light.

Stimulants like amphetamines speed up the central nervous system, causing the pupils to dilate. Conversely, drugs that stimulate serotonin agonize the 5-HT2A receptors in the brain, causing dilation. Horner’s syndrome also called oculosympathetic paresis, or Horner syndrome, comprises a constellation of clinical signs including the classic triad of ptosis, miosis and anhidrosis. Horner’s syndrome results from a lesion to the sympathetic pathways that supply the head and neck region, including the oculosympathetic fibers. The causes of Horner’s syndrome varies with the age of the patient and site of the lesion.
For miosis to happen, the dilator muscle of the iris must relax while the sphincter muscle of the iris acquires at the same time. Anyone experiencing Miosis for no apparent reason should also seek medical attention. People who have congenital miosis may also experience abnormal development of the whole anterior eye segment and are likely to have a higher risk of getting glaucoma. Any consistent presenting of miosis is cause to see a doctor because it could be a symptom of another underlying condition that is more serious. Age, injuries and inflammation to the eyes, some medications and a family history cause most of the cases of miosis. Miosis is a condition in which the pupils of the eyes are always too small, whether in light or dark.
