When should I use DET strips?
DET strips should be used during the slit lamp examination of a possible dry eye patient with complaints of burning, irritated eyes. DET strips can also be used to evaluate if a patient is an acceptable contact lens candidate. DET should be used any time that an accurate, reliable TBUT measurement is desired.
Why should I use DET strips instead of traditional fluorescein diagnostic strips?
The traditional fluorescein strip delivers up to 17 µL of fluid to the tear film, which floods the normal tear film's 3 to 7 µL volume. The tear film is not in a natural state due to the extra fluid added by the strip; therefore, TBUT is unreliable.
DET strips are designed to accurately measure TBUT in a repeatable fashion. The DET strip only adds 1 µL of fluid to the tear film, which does not compromise the TBUT reading. TBUT can be repeated at subsequent visits with confidence.
What should I use to wet the DET strip?
As with any diagnostic dye strip, non-preserved saline solution should be used to wet the DET strip.
Where can I get DET strips?
DET strips are available to ophthalmologists and optometrists exclusively at Amcon, the Eyecare Supply Center at www.amconlabs.com or by calling 1.800.255.6161.
How are DET strips packaged?
Sterile, dry DET strips are packaged in paper wrappers. Two DET strips are contained per pack, and fifty packs are placed into each dispenser box. Each DET strip should be used one time only.
Will patients notice a difference upon application of a DET compared to a traditional fluorescein strip?
Most patients are not fond of the sensation from a traditional fluorescein strip applied to the bulbar conjunctiva. However, the thin, smooth tip of the DET strip is composed of a lint-free material, so patients usually report little or no sensation upon application. Patient comfort promotes compliance of follow-up appointments.
