**What is a Welch Allyn Diagnostic Set?**

A Welch Allyn ophthalmoscope is an ophthalmoscope which is produced as a standalone tool or as a part of a complete diagnostic set. 

An ophthalmoscope is an instrument used to examine the eye's retina. It is the same instrument that an ophthalmologist uses to look at your retina while you are there for your eye check-up. There are two different types of ophthalmoscopes. First, the direct and second, the indirect one. A direct ophthalmoscope is useful for examining the centre of the retina, whereas an indirect ophthalmoscope helps check the entire retina of the patient.

These ophthalmoscopes use either halogen as illuminators or LED technology. This ensures a proper illumination that allows medical professionals to look at all parts of the retina. These come in different sizes and designs. A 3.5 V ophthalmoscope has a range of specialist features. Like an LED ophthalmoscope, it is light in weight, compact and easy to carry around. Other features include rechargeable lithium-ion power handles, which help increase the running time compared to the standard devices. 

**How Does Welch Diagnostic Set Work?**

The **[ophthalmoscopes](www.medguard.ie/ophthalmoscopes.html)** work by illuminating a dilated or undilated eye for the Welch Diagnostic set. It does this with the help of LED light, which allows the medical professional to see the various parts of the retina. The ophthalmoscopes focus on the fundus, a part of the eye that's made up of the retina, the optic disc and other blood vessels. It helps to check for multiple injuries and different conditions of our eyes.

An ophthalmoscope can be used to check for damage to the optic nerve, for retinal tear or detachment, for conditions like Glaucoma, Macular degeneration, Melanoma and so on. It can also help with diabetic retinopathy, hypertension, and other eye infections. Ophthalmologists check this part when screening for different conditions and diseases that can affect the eye.

Some advanced ophthalmoscopes also provide doctors with the aperture, lens and aperture/filter combinations to have a larger view of the eye. This helps specialists make a more accurate diagnosis and help the patient. 

**How to Use a Standard Ophthalmoscope from Welch Allyn?**

Tools like ophthalmoscopes should always be used by a trained professional only. It is not the case that the instrument is invasive, but incorrect use can lead to damaging the eye. Also, while using it, the patient must sit still and maintain a correct distance. Examination lights in the room should be turned down or switched off completely to optimize the retinal view.

Welch Allyn ophthalmoscopes are very intuitive to use. You need to do adjustments for the lens, lighting and filter by moving switches and dials on the ophthalmoscope head. Most of these adjustments are easy to make and can be made without removing the ophthalmoscope from the eye. It allows doctors to tune their examinations quick and easy. 

We can also apply filters to the ophthalmoscope to check different parts of the eye. The red filters are for blood vessels, and the other filters are for checking corneal abrasions.
