Dry eye is a multifactorial disease characterised by an insufficient protection of the ocular surface by the tear film.
Tears are a key barrier to defend the eye against external agents.
They keep the surface of the eye constantly moist and lubricated due to the complex mechanisms that regulate their production and evaporation.
The defence function of the tear film may be compromised due to:
The main symptoms of dry eye syndrome are the following:
Patients visit an oculoplastic surgeon for the following reasons:
In cases of Dry eye syndrome is important to have a discussion with the patient and do a series of specific tests to determine what is the primary cause in each individual case and then organise a personalised therapeutic strategy.
For cases in which medical therapy has not resolved the symptoms, with no eyelid associated alterations, it is possible to use PRP eye drops. The patient is subjected to a blood test, and through procedures standardised and approved by the FDA procedures, we extract the PRP (platelet rich plasma).
Platelets are ideal for producing growth factors and proteins which regulate the organisation, trophism and tissue regeneration within the human body. The PRP administration allows ocular surface regeneration and repair. For patients with dry eye syndrome due to alterations of the eyelids, surgery will be targeted to correct the eyelid defect.
The procedure results in a return of the patients quality of life; though apparently trivial, dry eye syndrome, when it becomes chronic, causes an intense pain that interferes with daily work and social life, and is perceived as highly debilitating to the patient.
