Dry eye test and meibography
The EyePhotoDoc’s LED exciter and barrier filter show more detail
A photograph is more descriptive than words. A video shows tear dynamics. Scientific explanation below
Most significant way to help your dry eye patients
Office tests for dry eye diagnosis have many non-conclusive tests. Unfortunately they are only suggestive such as the Schrimer test, TBUT, tear osmolarity, but are not diagnostic. Our advanced fluorescent Diode and yellow barrier filter find subtle punctate changes. Punctate stain is the only objective test for dry eye. It also tells the degree and severity that corresponds to patient’s complaints.
Photos help in patient follow up
This patient was treated for dry eyes. The left represents the original findings while the right shows the improvement a month later. Note the change in punctuate stain and the reestablishment of the tear film.
Below is an important new development. Watch the video of the blink and tear film dynamics. Note the tear film coating, it’s spread and breakup. This is called dynamic tear film analysis.
How this works: Yellow Barrier filter
Brighter and wider fluorescent diode beam
The special fluorescein exciting LED light is designed especially for diagnosis of external ocular tear film abnormalities. Unlike the typical slit lamp 10 mm blue light it is more intense and has a greater field. It allows you to see the lid action, tear film spread and breakup like never before.
Highly Recommended if your slit lamp does not have a yellow filter
Why this works better:
The standard slit lamp blue light washes out the fluorescent green detail. By using a yellow barrier filter the blue color is blocked and only the fluorescent detail is seen. The tear film and ocular surface disorders are easily seen. Click here for more videos
The legacy ‘tear break up time’ can be videoed for more understanding of the tear film behavior. The images can be used to show the patient and evaluated the efficacy of treatment.
The technology is ideal to evaluate different treatments. The before and after images help you decide on the type of drops, value of Restasis™️ and other meds in the category, punctal plugs, serum drops, meibomian treatments, etc
Now Photographic Meibography
The meibomian glands are sufficiently close to the surface allowing them to be photographed. By using the monochrome feature on your editing program the glands detail can be seen. Contact us for more information
Photographic meibography with monochromatic and inverse filters
Our newest advancement is green light meibography. Green is red free so it allows visualization of the glands or the vascular structures. By using a technique of bringing the light in from the side and rolling the glands completely into view they can be visualized on every patient even without a camera.
Using a camera gives higher resolution of detail compared to the IR meibography cameras. Above is a photo above as seen, middle monochromatic to accentuate the glands, and below an inverse demonstrating loss of vessels in dying glands.
Apple filter apps allow better visualization of meibomian structures
By using filter apps you can see the details of the glands allowing you to see the acinar spaces, obstructing particles and the vascularture.
It is a new tool to follow posterior blepharitis vascular inflammation. Serial photos allow an objective assessment of the progression and treatment.
