The Influence of Meibomian Gland Expression on Corneal Aberrations in MGD Patients

The Effect of Meibomian Gland Thermal Massage on Corneal Aberrations in Meibomian Gland Dysfunction Patients

To evaluate the influence of corneal-aberrations before and after the meibomian gland thermal massage treatment.

62 MGD patients treated with meibomian gland thermal massage once a week for 3 to 4 weeks were recruited.The Ocular Surface Disease Index questionnaire; tear film assessment encompassing tear meniscus height and non-invasive keratograph breakup time ; meibography score,corneal fluorescein staining; the Schirmer I test ; expressible meibomian gland, and quality ,anterior and total corneal aberrations were evaluated before and after treatment.

Inclusion Criteria:

• tear break-up time (BUT) ≤10 seconds or Schirmer I test (SIT) ≤10 mm, the presence of dry eye symptoms, and fluorescein staining (FL) score <3 points and at least one lid margin abnormality and poor meibomian gland expressibility

Exclusion Criteria:

• eyelid structure abnormal(Entropion , ectropion);
• having received any other treatment for MGD within three months
• history of ocular surgery
• contact lens use
• ocular infection
• any type of corneal scarring
