Meibomitis and meibomian gland disease
More than 60 percent of dry-eye sufferers have meibomian gland disease (MGD)! MGD is not cured by drops which explains why many patients still have dry eyes after using eye drops as eye drops don’t treat MGD. It’s well-accepted that meibomitis is characterized by abnormal meibum secretions, differing from normal secretions in viscosity and/or color as well as physical composition.
Hypersecretion of meibum or oil happens during infrequent blinking while using digital devices or reading. Infrequent blinking causes less lubrication across the eyes, thus stimulating Meibomian glands to produce excessive meibum, resulting in blockage of glands overtime.
Blepharitis
This is inflammation of the eyelids, in which the eyelids become red, itchy and irritated. This is due to the overgrowth of bacteria along the lid margins.
Contact lens wear
Contacts lenses hinders the proper distribution of tears over the surface of the eye.
This can be made worse by lens material , lens protein deposits, size of lens and lens solutions.
Refractive eye surgeries
Dry eye is the most common complaint or adverse event after LASIK.
Hormonal deficiencies or changes
Thyroid conditions and hormonal changes during menopause are also the common factors that are associated with dry eyes.
