Diagnostic tools allow clinicians the opportunity to effectively assess the underlying cause and diagnose dry eye earlier in the disease process.
Meibomian gland exam
Meibomian gland dysfunction (MGD) is the most common cause of evaporative dry eye.7 All dry eye evaluations should include a meibomian gland exam and gland expression.
Meibum should be clear and oily and express easily in patients with healthy glands; meibum will be thick and discolored in patients with MGD and more difficult to express.
Meibography can be used to view the anatomical structures of the meibomian gland, and the imaging can be used to educate patients on the severity of their DED.
Systems include the LipiView II (Johnson & Johnson Vision), LipiScan (Johnson & Johnson Vision), and Meibox (Box Medical Solutions Inc.).
