The capillaroscope (also known as capillaryscope) is a handheld microscopy device. It is used to inspect blood capillaries during a nailfold capillaroscopy procedure.
Several brands of these devices exist. In this article, we are going to present the best capillaroscopes and compare their features, quality, and cost.
Let’s first understand more about the best capillaroscopes and capillaroscopy.
What is capillaroscopy and why is it done?
As we know microcapillaries help transport oxygen, nutrients, and water to myocardial tissues. This microcirculation occurs in the arterioles, venules, and capillaries.
Capillaroscopy is a specialized diagnostic test, which helps monitor the health of our body’s microcirculation. It can provide insights about a patient’s disease: more importantly it allows us to make an early diagnosis. Swollen, bleeding, or completely absent nailfold capillaries can be indicative of signs of illness.
With the capillaroscopy test, patients can be informed of any potential health concerns and be diagnosed and treated for their conditions.
A medical review published in BioMedical Research International, discusses common approaches for measuring capillary dimensions.
There are a myriad of microscopy options available. Choosing the right setup can mean a world of difference in diagnosis and management of capillaroscopies.
How a premium-quality immersion oil can improve the effectiveness of your capillaroscope
Imaging devices may not always provide the best pictures of the treatment site. The image may come out blurry or blown out of proportion—due to the patient’s body shape and capillary position. In such cases, it can be challenging for physicians to correctly diagnose the patient’s conditions and provide the treatment.
Immersion oils are designed to improve the images produced by imaging devices such as the capillaroscope. When capillaroscopy is performed, a drop of immersion oil is placed on the nailfold. The device is then placed on the lubricated area and the imaging is performed. A skin-friendly, immersion oil is used. It will have the same refractive index as that of the glass lens used in the capillaroscope. More light is directed through the immersion oil, allowing physicians to obtain a sharper and brighter image of the patient’s capillaries.
High resolution images produced during the nailfold capillaroscopy give visibility into their shape, size, condition, and health of a patient’s capillaries. This can lead to greater satisfaction and patient compliance.
Which Capillaroscope is the Best?
There are numerous brands on sale today, we have found that the most widely used brands include the following options:
- Smart G-Scope
- Inspectis Digital Capillaroscope
- Dino-Lite CapillaryScope
- Optilia Digital Capillaroscope
We will study these brands in detail to help you determine if any of these brands are suitable for use or not.
First, we will dive deeper into the available options.
Why are capillaroscopes the best equipment for the nailfold capillaroscopy procedure?
Capillaroscopes aren’t the only imaging tools used by physicians to diagnose any pathological problems during a nailfold capillaroscopy. When it comes to dermatological imaging, physicians also use a dermatoscope, a microscope, or other USB imaging devices. While they’re helpful in their own way, they aren’t equal to this instrument during nailfold capillaroscopy.
Capillaroscope vs dermatoscope
A dermatoscope is used to identify and diagnose skin lesions. It is better at tracking more dramatic changes in the skin’s tone, texture and health. Often, capillaries may have subtle changes, which cannot be picked up by the dermatoscope. Physicians need a device which is significantly more powerful. It allows thorough detection of minute capillary changes.
Capillaroscope vs handheld microscope
While a handheld microscope is easy to use, it doesn’t come with USB connectivity. It helps transfer data collected from the patient onto the doctor’s laptop or other medical equipment. Images seen during the capillaroscopy can’t be stored for later perusal. This makes it difficult to treat patients due to limited information. Whereas, most state-of-the-art capillaroscopes come with a USB cable.
Capillaroscope vs magnifying glass
A magnifying glass doesn’t possess the intense magnification needed to identify pathological changes in the capillaries. It has only 5X to 10X magnification. Only very severe dilation may be visible faintly through a magnifying glass, even if it has a built-in light source. On the other hand, a capillaroscope’s magnification can reach up to 1000X.
Capillaroscope vs ophthalmoscope
An ophthalmoscope is a specialized device used to examine the eye. While this tool does support imaging, it is not powerful enough to provide images of tiny capillaries or nascent signs of damage. Additionally, ophthalmoscopes don’t come with storage ability and may be difficult for physicians to use due to their shape and size (which can be incompatible with the shape, size, and location of the nailfold). This makes them weak alternatives to capillaroscopes, which are better suited for capillaroscopy.
Capillaroscope vs Stereomicroscope
A Stereomicroscope is a tool used for imaging that requires lower levels of magnification. It is better suited to study solid specimens and surfaces while not being ideal for smaller capillaries during nailfold capillaroscopy. Stereomicroscopes require users to be specially trained in using them, which can add to time and expense. For taking photos, physicians will need to attach an additional camera to the Stereomicroscope. In comparison, a capillaroscope will already have the required technology needed to support capillaroscopy.
Capillaroscope vs Video capillaroscope
The only imaging diagnostic equipment that can be considered as a good substitute for this instrument is the video capillaroscope. This device offers all of the features and more as a traditional gadget. However, the biggest problem is that the video capillaroscope is immensely expensive and most clinics and small hospitals may not be able to afford it. The equipment cannot be used at bedside. A video capillaroscope is a poor investment for regular use diagnostic use.
Top 5 reasons that a capillaroscope is the right choice for a purchase today
Considering the above, it’s safe to say that the primary reasons why a traditional scope is the best option for nailfold traditional capillaroscopy are as follows:
It’s a portable device
The conventional scope is a handheld device, making it very easy to use during bedside consultations.
It offers excellent magnification and focus
Given that most devices can have high magnification, it is very easy for physicians to find high-focus capillaroscopes for their diagnosis. Furthermore, capillaroscopes don’t suffer from much distortion, especially if physicians use a good quality immersion oil to conduct the nailfold capillaroscopy.
It produces high-resolution images
These devices are designed to offer premium-quality images, compared to other imaging diagnostic devices. In fact, you can adjust the settings of the capillaroscope’s camera to get the bespoke picture you want. It’s very easy to get complete and clear visibility into a patient’s microcirculation health through the capillaroscope. This supports an accurate diagnosis.
It allows physicians to see difficult-to-distinguish capillary changes
Capillaroscopes benefit from polarization, which allows physicians to make out the most nuanced details on the nailfold. As previously stated, this allows a physician to catch the early signs of disease and to provide treatment of the condition.
It automatically calibrates to the test requirements
Finally, capillaroscopes auto-calibrate based on the test conditions. This permits physicians to see the patient’s capillaries clearly. Once the initial set-up is done, there isn’t much that is needed to change or adjust when using the capillaroscope for nailfold capillaroscopy.
