Enlarged Pupil

Causes of Enlarged Pupil

There are various reasons why pupils may enlarge, including:

• Natural response to darkness: The pupils dilate to let more light in when it’s dark.
• Medications: Certain eye drops, antihistamines, or antidepressants can cause temporary pupil enlargement.
• Eye trauma: Physical injury to the eye can result in pupil dilation.
• Nervous system disorders: Conditions like Horner’s syndrome or Adie’s pupil may lead to persistent enlargement.
• Brain injury or tumor: Damage to the brain or pressure from a tumor can affect the nerves controlling pupil size.
• Substance use: Use of drugs like cocaine, amphetamines, or marijuana can dilate pupils.

Types of Enlarged Pupil

Enlarged pupils can be classified based on the underlying cause:

1. Physiological Mydriasis: Occurs naturally in response to low light.
2. Pathological Mydriasis: Caused by injury, disease, or medical conditions.
3. Pharmacological Mydriasis: Results from the use of specific medications or drugs.

Symptoms of Enlarged Pupil

While the enlarged pupil itself is noticeable, it can be accompanied by other symptoms depending on the cause:

• Increased light sensitivity (photophobia)
• Blurred vision
• Difficulty focusing on objects
• Eye pain or discomfort, especially if caused by trauma or infection
• Headaches in cases of brain-related causes
• Drooping eyelid in conditions like Horner’s syndrome

Diagnosis of Enlarged Pupil

At Dr. Suraj Munjal’s clinic, we use advanced diagnostic tools to evaluate the condition and pinpoint the underlying cause. Diagnostic procedures may include:

• Detailed eye examination: Assessing the pupil’s reaction to light and checking for any physical abnormalities.
• Slit-lamp examination: To closely examine the eye’s structure.
• Neurological tests: In cases where a brain or nerve issue is suspected.
• Imaging tests: Such as MRI or CT scans if there’s suspicion of a brain tumor or injury.

Treatment for Enlarged Pupil

The treatment for enlarged pupils depends on the underlying cause:

• Addressing the root cause: Treating the condition responsible for the pupil dilation, such as eye infections, trauma, or nerve damage.
• Medication adjustments: If pupil enlargement is caused by medication, switching or adjusting the dosage may resolve the issue.
• Surgical intervention: In severe cases where trauma or tumors are involved, surgery may be required.
• Protective eyewear: Patients with light sensitivity may benefit from wearing protective eyewear, such as sunglasses, to reduce discomfort.
