Posterior blepharitis, meibomian gland disease- it has several names, we see it very often, and it’s difficult to control. We typically try antibiotic drops/ointment, steroid drops, hot compresses, lid hygiene, Restasis, flaxseed oil etc. Dr. Maskin has come up with a novel idea of probing each gland with a special probe he developed with Rhein, which clears obstruction of the glands and allows the lipid to drain effectively. He claims his patients get many months of relief, and can be repeated. The probes are now commercially available- may be worth a try
