TearFlo™ Sterile tear flow strips (Schrimer test)

TearFlo™ is being used to evaluate tear secretion – Schirmer’s test.  More than 13 mm wetting of standardized strips folded at a given notch over a 5-minute period of examination with eyes closed is considered to be normal tear secretion. Wetting values less than 9 mm are considered as hyposecretion.

Schirmer’s test is the oldest method available for Dry Eye Disease diagnosis.

Method of a performance:

Test is performed in a room with a dimmed light, without a draught, and without pressure sources in the field of
vision.

Patient is advised to look straight ahead or slightly upward and not to force himself/herself to blink the eyes.

Tear fluid should be removed from the lower fornix using a gauze swab before paper strips are placed.

Strip should be bent at the notch on the marked end using forceps and inserted in the lower part of the conjunctival sac at 1/3 of length of the lid margin on the outer side.

Strip is removed from the conjunctival sac after 5 minutes, and the amount of wetting of the filter paper section is measured in millimetres from the place of bending.

Results interpretation:

=>15 mm – normal;

>10 to 15 mm – initial stage of the tear deficit; >5 to 10 mm – advanced tear deficit;

5 mm – severe tear deficit.

Available packages:
