Depression and dry eye disease: a need for an interdisciplinary approach?

Area of Science:

• Ophthalmology
• Psychiatry
• Epidemiology

Background:

• Dry eye disease (DED) is a prevalent ocular condition characterized by tear film dysfunction, leading to ocular discomfort and visual disturbances.
• A significant discrepancy often exists between objective DED signs and subjective symptoms, with symptoms sometimes correlating more strongly with psychiatric conditions like depression and PTSD.
• The interplay between DED and mental health conditions, particularly depression, suggests a complex bidirectional relationship impacting patient well-being.

Purpose of the Study:

• To investigate the prevalence of anxiety and depression in patients diagnosed with dry eye disease (DED).
• To explore the relationship between the severity of DED and the presence of anxiety and depressive symptoms.
• To examine the implications of this comorbidity for patient management and potential therapeutic strategies.

Main Methods:

• A comprehensive meta-analysis was conducted, synthesizing data from 22 distinct studies.
• The analysis included a large patient cohort, encompassing approximately 2.9 million individuals.
• Prevalence rates of anxiety and depression in DED patients were compared against control groups.

Main Results:

• Patients with dry eye disease (DED) exhibit a higher prevalence of anxiety and depression compared to individuals without the condition.
• A positive association was found between the severity of DED and the intensity of anxiety and depressive symptoms.
• Selective serotonin reuptake inhibitors (SSRIs), commonly used for depression, may potentially worsen DED symptoms, complicating treatment.

Conclusions:

• Dry eye disease (DED) and depression are closely interconnected, creating a synergistic feedback loop that significantly affects patients' quality of life.
• Integrated care approaches involving collaboration between ophthalmologists and psychiatrists are recommended for optimal management of patients with co-occurring DED and depression.
• Future research should focus on identifying therapeutic targets for DED-associated depression, considering the challenges posed by current antidepressant medications.
