*A history of damage of the eye
*Risk of having stroke

Eyelids:examine the lid position and closure and check for entrepion(when eyelid turns in on itself),Trichiasis(lashes touching the eye) and lagophthalmos(a gap between between the upper and lower lid when the eyes are closed). Examine the lid margin and meibomian gland opening for abnormal positions,inflammations and plugging with secretions.Try to express the meibomian glands,using gentle pressure.
Tears:Assess the quality of the tear film by looking for discharges,debris and the tear m…
