Look for the features designed to make your examinations easier and more comfortable. The All Pupil II is based on the design of the number-one selling All Pupil indirect. But be mindful that it does take practice.Another Bright Idea From Keeler вЂ“ LED Illumination & Slimline Polymer Battery However, if you do have a bio headset available, I would encourage you to give it a go (depending on the nature of your examination and the patient). IвЂ™m not surprised that the binocular indirect ophthalmoscope isnвЂ™t a popular piece of equipment as it is unfamiliar for so many of us, even for optometrists in hospitals. The real game changer for me is when I manage to achieve a glimpse of the fundus that I might not have otherwise achieved, as this can really make the difference between a timely diagnosis and a more accurate referral to the ophthalmologist. My paediatric patients respond well to my вЂrobot hat,вЂ™ and I always have a few illuminated toys or a flashing disco ball to help distract them while carrying out the exam. Therefore, I find it best to make a joke of this.

The real game changer for me is when I manage to achieve a glimpse of the fundus that I might not have otherwise achieved, as this can really make the difference to a timely diagnosis or a more accurate referral to the ophthalmologistДЄs we know, the binocular indirect ophthalmoscope isnвЂ™t the most fashionable piece of equipment in our armoury. If possible, coordinating with cycloplegic refraction is advisable, to save the patient being dilated twice. Especially when you are learning the technique, examination is much easier on a dilated pupil. Secondly, optometrists should be aware of dilation. Firstly, it provides low levels of magnification, and high levels of illumination. Of course, with every piece of equipment there are disadvantages to consider. Higher powered lenses are also advantageous for those with smaller pupils. They have to be held closer to the patientвЂ™s eye and are smaller in diameter, so might also be preferred by practitioners with smaller hands. It is important to note that the higher-powered lenses offer less magnification, but a greater FoV.

Therefore, this lens could be preferred if you were prioritising a full retinal examination. While a 20D lens is a standard lens for general examination, allowing x3 magnification and a FoV of approximately 45 degrees, a 30D lens offers x2 magnification, but a larger FoV of approximately 65 degrees. For example, the practitioner can control what they are prioritising by changing the power of the condensing lens. This is great for screening as you can see gross abnormalities in a glance as you can see the optic nerve and macular in the same view.ДЇurthermore, it allows the optometrist to prioritise the magnification or field of view (FoV). Using a 20D lens, for example, the practitioner can achieve a view equivalent to approximately eight disc diameters. I have also found patients to be less intimidated by this. It has a longer working distance that allows the examiner to be at armвЂ™s length from the patient, which is more appropriate for testing than other techniques during the pandemic.

It is portable and could also be great for those carrying out domiciliary work. It is suitable for all patients: children, newborns, adults, those who are wheelchair users and those with learning difficulties. It provides a clear image and is quick to perform, once you learn the technique, and it is great for those patients who have вЂants in their pantsвЂ™ and donвЂ™t have steady fixation. There are many benefits of the bio headset for an optometrist in day-to-day testing. Like anything, with practice and patience, I have become a big advocate of the bio headset I also feel it has been a very reliable piece of equipment while working throughout the COVID-19 pandemic as it gives a good fundus view from armвЂ™s reach. However, like anything, with practice and patience, I have become a big advocate of the bio headset. I remember picking up the bio headset at university for the first time and thinking вЂGood job IвЂ™ll never need this in practice.вЂ™ I thought it was mainly used by ophthalmologists and I was certainly not in a rush to pick it up when I started in the hospital clinic.

While both are excellent pieces of equipment, they do depend upon your patientsвЂ™ cooperation.ДЄs a hospital optometrist I carry out a lot of fundus examinations on both children and those with learning difficulties, which is why I absolutely could not live without my binocular indirect ophthalmoscope. Fundus examinations have always been a key role for optometrists, and IвЂ™m sure most will use either a direct ophthalmoscope or a Volk lens to carry out fundus examination.
