Intraductal Meibomian Gland Probing (MGP) has now been shown by multiple independent investigators to relieve gland obstruction, stimulate meibum secretion, and relieve symptoms and signs of obstructive Meibomian Gland Dysfunction (MGD).

MGP is the only way to establish or confirm, with positive physical proof, that the orifice, duct, and Meibomian Gland (MG) are unblocked and functional. 

Probe findings suggesting internal ductal strictures secondary to periglandular fibrotic obstruction occur in at least 66% of all glands (submitted for publication), and are relieved with MGP, safely restoring integrity to the intraductal space allowing the gland to resume function and potentially regrow.

After MGP, Meibum Secreting Lid Functionality (MSLF) and number of expressible glands dramatically improve. Studies have shown rapid and dramatic reduction of symptoms of obstructive MGD after MGP using Maskin® Probes and the associated Probing protocol.
