Visualize Acinar Structures

You can see Incredible detail by increasing magnification on your slit lamp. Unlike lower resolution IR infrared meibography, the detail of each acinar structure can be seen. The resolution is 25 times greater and the only limitation is optical zoom. 

Each acinar structure can be seen early in the course of the disease. This is important since you want to discover problems earlier.  It also allows you to track effects of treatment.

Meibography

Speed meibography is done in red free green or black and white using a camera. Either shows abnormalities. The diagram demonstrates the common abnormalities. This adds to the traditional meiboscores by being higher in resolution and showing the acinar structures.

Use of the EyePhotoDoc camera to analyze and track treatment

The camera along with Apps allow you to document findings. You can make them into black and white monochromes to resemble the IR meibography. Indeed that will increase contrast and make it feel ‘familiar’.  

Using the finger stretching of the photo allows you to enlarge the area of interest for easier diagnosis. The iPhones with 48 megapixels are ideal. 

Case study

When you study this low magnification photo can you see the abnormalities of the glands?  Using your slit lamp you can zoom up and see incredible detail. Remember your eyes have 40 times the resolution of the 12 megapixel camera!

Find:

1. Missing glands

2. Dilated acinar structures

3.  Missing acinar structures in gland

4. Segmented glands

5. Fun bonus question  Can you see the accessory lacrimal glands?

Can you find the abnormality?
