Dry eye: what are the symptoms and how is the treatment to be followed?

Dry eye is a multifactorial pathology due either to a deficiency of the tear film or to an imbalance of the components of this tear, which makes it unstable and abnormal.

Whatever its cause and type, it usually triggers a set of very frequent and annoying ocular symptoms, such as gritty sensation, stinging, itching, tearing, redness, prickling, pain, etc.

What are the causes of this pathology?

The causes are many and varied, including: essential lacrimal hyposecretion, associated systemic diseases, taking certain medications, excessive work with screens, outdoor activities, allergies, blepharitis, etc.

How can it be treated?

Dry eye is usually treated with supportive measures such as ocular lubricants (eye drops, gels), local or systemic anti-inflammatories, ointments, autologous serum, secretagogues, among others.

Are the results of the treatment favorable and definitive?

As it is a multifactorial pathology, there is no single treatment for all patients, but it must be personalized and administered following a therapeutic ladder from less to more, until the symptoms are considerably alleviated.

On the other hand, treatments are not usually definitive and we do not usually speak of cure, but rather of symptom control and stabilization of the condition.
