Dry Eye Reviews

Some investigations should be done to determine the condition of dry eye. These measurements alone are not sufficient. Daily life and situations at different times should also be considered. All of these should be brought together and the dry eye should be evaluated.

Determination of corneal injury: The front lens of the eye, the cornea, is a very delicate tissue. It is very much affected by thirst. The structure of the cells deteriorates, begins to peel off, tissue losses occur. When viewed with cobalt blue with fluorescein dye, the distorted areas give a green image.

Density (osmolarity) of the tear: The osmolarity, that is, the consistency and density of the tear, is also important. If it is less, it will become sedimentary. Sedimentation gives the appearance of burrs. It is in the state of the dirty eye and the stinging eye. The density should be at a normal level. The ophthalmologist already evaluates this at the time of examination.

Tear break-up time examination: It’s time to tear apart the tear film. This period is shortened in dry eye.

Fluorescein, which gives color to the eye, is dripped. The patient looks fixed after blinking 3 times in a row. It is viewed with cobalt blue under the microscope. Fracture manifests itself as black dots. This refraction is around 10 seconds in the healthy eye. It shows dry eye for a shorter time.
(4.14+3.84 is the first time it is broken. The last is 10.6 +4.01 seconds.)

Schirmer test: A special test paper in the form of a strip is folded and placed on the outer 1/3 of the lower eyelid. He is asked to make normal eye movements.

Wetting less than 5 mm after 5 minutes is a cause of dry eye.

Between 5-10 is a suspected dry eye condition. Must watch.

More than 10 mm indicates no dry eye.
