The Neurological Effects and Causes of Dilated Pupils

Causes of Dilated Pupils

There are various causes for dilated pupils, which can be physiological or pathological.

Physiological Causes

• Low light levels
• Emotional arousal
• Medications (e.g., atropine, scopolamine)

Pathological Causes

• Eye injuries or diseases
• Neurological conditions (e.g., seizures, traumatic brain injury)
• Drug use (e.g., cocaine, LSD)

Neurological Effects of Dilated Pupils

Dilated pupils affect the visual and neurological systems in multiple ways:

Visual Impairment

• Reduced visual acuity
• Glare sensitivity
• Blurred vision

Neurological Effects

• Altered pupillary light reflex
• Communication difficulties
• Impaired coordination

Diagnosis and Treatment

The diagnosis of dilated pupils involves a thorough eye examination and a detailed medical history.

Treatment

• Treating the underlying cause (e.g., medication, eye disease)
• Pupillary dilation eye drops
• Sunglasses
