kyynelvuoton

Kyynelvuoto, scientifically known as epiphora, is a medical condition characterized by excessive tearing of the eyes. This can occur due to various reasons, including overproduction of tears or inadequate drainage of tears from the ocular surface. Tears are essential for lubricating the eyes, washing away debris, and protecting against infection. However, when this delicate balance is disrupted, epiphora can result.

Common causes of kyynelvuoto include irritations to the eye surface, such as allergies, foreign bodies, or dry eye syndrome, which paradoxically can lead to increased tearing as the eye tries to compensate for dryness. Blockages in the tear drainage system, including the puncta, canaliculi, or nasolacrimal duct, are also frequent culprits. These blockages can be congenital, developing from infections, inflammation, or trauma. Eyelid abnormalities, such as ectropion (eyelid turning outward) or entropion (eyelid turning inward), can also affect tear drainage and lead to excessive tearing.

Symptoms associated with kyynelvuoto can range from mild annoyance to significant visual disturbance. These include a constant feeling of wetness in the eyes, blurred vision, and sometimes skin irritation around the eyes due to the constant moisture. Diagnosis typically involves a comprehensive eye examination to identify the underlying cause. Treatment strategies are tailored to the specific etiology and may involve artificial tears, topical medications to reduce inflammation, punctal plugs to help with drainage, or surgical interventions to correct blockages or eyelid issues.
