A detailed guide to your diabetic retinal screening appointment. Understand what fundus photography involves, how to prepare, and how your results are reported.
Diabetic retinopathy is one of the leading causes of preventable blindness in working-age adults. It occurs when chronically elevated blood glucose causes damage to the small blood vessels supplying the retina, which is the light-sensitive layer at the back of the eye. In its early stages, diabetic retinopathy causes no symptoms and cannot be detected without a direct examination of the retina. By the time vision is affected, significant and often irreversible damage has already occurred.
Annual retinal screening is recommended for all patients with type 2 diabetes from the point of diagnosis. Regular screening allows early changes to be identified and treated before they progress to sight-threatening disease. Attending this screening every year is one of the most important steps you can take to protect your long-term vision.
We use a portable, non-mydriatic handheld fundus camera to capture high-resolution photographs of the retina. Non-mydriatic means that no pupil-dilating eye drops are required in most cases. The examination is comfortable, takes only a few minutes, and does not affect your vision or your ability to drive afterwards.
Images are captured in multiple modes to allow thorough assessment of retinal structures. Your fundus photographs are then sent securely to a qualified specialist ophthalmologist for review and grading. The ophthalmologist assesses the images for signs of diabetic retinopathy, macular changes, and other relevant findings, and produces a written report. This arrangement means you receive specialist-level retinal assessment without the time and logistics of a separate hospital or ophthalmology clinic appointment.
Diabetic retinopathy is classified in stages. The grading system used by your reviewing ophthalmologist is as follows.
No retinopathy detected: No visible changes to the retinal blood vessels are present. Annual rescreening is recommended to continue monitoring.
Mild non-proliferative retinopathy: Early microaneurysms are present. This finding indicates that optimising glucose, blood pressure, and lipid control is important. Increased screening frequency will be recommended.
Moderate to severe non-proliferative retinopathy: More extensive vascular changes are visible. An ophthalmology referral for consideration of treatment will be arranged.
Proliferative retinopathy or macular involvement: An urgent ophthalmology referral is required. Laser photocoagulation or intravitreal injection treatment may be recommended by the specialist.
Please note: in some cases where image quality is insufficient due to small pupil size or other optical factors, mydriatic drops may be required. The clinical team will advise you at the appointment if this applies. If dilating drops are used, your vision will be temporarily blurred for a few hours and you should not drive until it has fully cleared. Please arrange for someone to drive you if there is any possibility this may apply to you.
Your fundus photographs are reviewed by the specialist ophthalmologist and a report is returned to Vitalis Health. The findings are then discussed with you by your physician at a follow-up consultation. If no retinopathy is detected, annual rescreening is scheduled. If early or moderate changes are found, your diabetes management plan is reviewed and the frequency of screening is increased. Patients with findings that require direct ophthalmology care are referred appropriately with all relevant documentation.
No. The examination involves sitting comfortably while the camera is brought close to your eye to capture the photographs. There is a brief flash of light for each image. The process is quick and entirely painless. No contact is made with the eye.
In most cases, no. Our fundus camera is non-mydriatic, meaning it is designed to capture retinal images without dilating drops in the majority of patients. In a small number of cases where image quality is insufficient, dilating drops may be needed. The clinical team will advise you at the appointment if this applies.
Yes, in the standard non-mydriatic protocol. If dilating drops are required, your vision will be temporarily blurred and you should not drive until it has fully cleared, which typically takes a few hours. If there is any possibility that dilation may be required, please arrange for someone to accompany you.
The photography itself takes approximately 5 to 10 minutes. Including the brief history review and preparation, the full appointment is typically 15 to 20 minutes. Additional time will be needed if a physician consultation is scheduled alongside the screening.
Your photographs are reviewed by a specialist ophthalmologist and the report is returned to Vitalis Health. Your physician will contact you to schedule a follow-up consultation to discuss the findings. Urgent findings are communicated as a priority.
Yes. This is the most important reason for annual retinal screening. Diabetic retinopathy in its early and treatable stages causes no visual symptoms at all. By the time vision is affected, significant damage has already occurred and treatment options are more limited. Attending annual screening when you have no symptoms is precisely how serious complications are prevented.
If early changes are found, your physician will review your diabetes management plan with the aim of improving glucose, blood pressure, and lipid control, and will increase the frequency of your retinal screening. If more advanced changes are detected, you will be referred to an ophthalmologist for specialist assessment and treatment. Early-stage retinopathy is very often stabilised or reversed with improved metabolic control.
No. A standard optician's eye test assesses vision, refraction, and the health of the front of the eye. Diabetic retinal screening specifically examines the retina at the back of the eye using fundus photography to detect the vascular changes caused by diabetes. The two examinations are complementary and both are important, but they serve different purposes. Having a regular optician's eye test does not replace diabetic retinal screening.
