Posterior bleph.
Excessive and abnormal meibomian gland secretion,
manifesting as capping of meibomian gland orifices with
oil globules (Fig. 1.43A).
○ Pouting, recession, or plugging of meibomian gland
orifices (Fig. 1.43B).
○ Hyperaemia and telangiectasis of the posterior lid
margin.
○ Pressure on the lid margin results in expression of
meibomian fluid that may be turbid or toothpaste-like (Fig. 1.43C); in severe cases the secretions become so inspissated that expression is impossible.
○ Lid transillumination may show gland loss and cystic dilatation of meibomian ducts.
○ The tear film is oily and foamy and often unstable, and froth may accumulate on the lid margins (Fig. 1.43D) or inner canthi.
