Chapter 9 — How Is Demodex Around the Eyelashes Diagnosed?
A dramatic photograph cannot diagnose Demodex.
An eye-care professional can examine the eyelids and eyelashes under magnification. In some circumstances, eyelashes can be sampled and examined
microscopicallyfor mites. Cleveland Clinic
Doctors may also look for characteristic cylindrical dandruff or collarettes around the base of the eyelashes, which can provide an important clue. EyeWiki
This matters because many eye conditions have overlapping symptoms.
For example, itchy and red eyelids could result from:
- Allergies
- Dry eye
- Bacterial blepharitis
- Seborrheic dermatitis
- Rosacea
- Meibomian gland dysfunction
- Demodex-associated inflammation
A proper examination helps distinguish these possibilities instead of relying on a viral image.
