Signs of Dry Eyes
Signs of dry eyes are those things that your doctor will find during eye examination by using slit-lamp and these signs are:
1- Blepharitis especially posterior blepharitis with meibomian gland dysfunction.
2- Conjunctival redness and hyperemia. In case of chronic dry eye and in xerophthalmia there will be conjunctival keratinization which means that epithelium of the Conjunctiva changed to skin like epithelium.
3- With each blinking we might see small particles and debris the moves over the cornea.
4- Froth in the tear film or on eyelid margin. we can see this sign especially in meibomian gland dysfunction.
5- Small erosions on epithelial layer of the cornea called corneal abrasion. These erosions stained with special dye called fluorescein. Those erosions present in the middle and lower part of the cornea.
6- Small collection of epithelial cells, proteins and mucous can be deposited on cornea surface forming filaments or mucous plaques. These plaques can be stained with fluorescein or rose Bengal stain.
7- In chronic severe cases we can see thinning of the cornea which can lead to perforation with minor trauma.
