Want to diagnose Demodex? Use more mag.
A new study shows that rather than using a light microscope to detect Demodex, mites can be visualized by using the slit lamp and a 90 D lens.
Tell me more.
The study published in Cornea included 16 patients with blepharitis and cylindrical dandruff. Two lashes from each patient were epilated, mounted on a slide, and viewed with the slit lamp and a 90 D lens. The slides were then viewed under a microscope to confirm the presence of Demodex. The ability to determine the presence of mites with only slit-lamp examination was 91.4%.
How do I use the slit lamp to do this exactly?
In the study, the epilated lashes were placed on a glass slide and a drop of fluorescein was added. A coverslip was mounted on each slide and attached with an adhesive tape to prevent slippage. The slides were placed on a strip of white paper (to serve as a clear background) and examined under a slit lamp with a 90 D lens to achieve better visualization. The presence and number of mites was documented.
The take home:
You don't need a light microscope to visualize Demodex. Demodex infestation in patients with blepharitis and cylindrical dandruff can be confirmed using only a slit lamp and common eye clinic equipment.
