Effectiveness of pharmaceutical interventions for meibomian gland dysfunction: An evidence-based review of clinical trials.

Meibomian gland dysfunction is one of the most common ocular disorders encountered by ophthalmologists and is the leading cause of evaporative dry eye. The disease causes significant morbidity in the population such that patients seek treatment. Multiple clinical studies on pharmacological and mechanical interventions for the treatment of meibomian gland dysfunction have been evaluated. However, there is limited comparative clinical evidence for the effectiveness of these interventions. This review paper aims to report the clinical evidence for pharmaceutical interventions for meibomian gland dysfunction in order to guide clinicians in the management of the disease.
