MENTAL DISORDERS AS INFLUENCING FACTORS FOR DISCORDANCES IN THE SIGNS AND SYMPTOMS OF DRY EYE DISEASE

Dry eye disease (DED) is a multifactorial disease of the tear film and ocular surface representing one of the most common problems in ophthalmological practice. Characteristic symptoms of DED include gritty, sandy foreign body sensation as well as he symptoms of dry eye are the main features of this disease, however, the symptoms do not always coincide with the signs and the results of diagnostic tests and the cause of this discordance in perception is still unclear. Numerous studies have been conducted in order to determine the cause of these discrepancies. Mental health disorders may be one of considerable contributing factors for dry eye symptoms and undiagnosed mental health conditions can be an influencing element for unexplained levels of DED symptoms. Depression, anxiety, stress, hypochondriasis, neuroticism, sleep and mood disorders may be associated with the exacerbation of symptoms to degrees that are not consistent with the objective signs related to tear dysfunction as well as changes in the anterior surface of the eye. Thus, a detailed medical history, thorough ophthalmological examination and referral to a psychologist or psychiatrist may be essential in the treatment of patients whose symptoms do not correlate with objective evidence of DE
