Changes in corneal topography and tear film stability due to a single Meibomian cyst.
Lid pressure may affect corneal curvature. A change in lid pressure due to a Meibomian cyst may cause a change in corneal topography and possibly in refractive status. External infection or epithelial surface disruption may affect the stability of the precorneal tear film by causing changes in tear formation or an increase in the rate of evaporation of water from this film. This report concerns a male patient who showed changes in corneal topography and tear film stability due to a Meibomian cyst.
