Risk Factors for Diabetic Retinopathy Anyone with type 1 , type 2 , or gestational diabetes diabetes while pregnant can develop diabetic retinopathy. These factors can also increase your risk: Blood sugar , blood pressure, and cholesterol levels that are too high.

Help for Low Vision. Symptoms in the advanced stage can include: Blurry vision Spots or dark shapes in your vision floaters Trouble seeing colors Dark or empty areas in your vision Vision loss How Diabetic Retinopathy Is Diagnosed During your eye exam, your eye doctor will check how well you see the details of letters or symbols from a distance.

Changes may include: Blurring Spots Flashes Blind spots Distortion Difficulty reading or doing detail work. Diabetic Retinopathy Treatment Treating diabetic retinopathy can repair damage to the eye and even prevent blindness in most people.

Options include: Laser therapy also called laser photocoagulation. This creates a barrier of scar tissue that slows the growth of new blood vessels.

Medicines called VEGF inhibitors, which can slow down or reverse diabetic retinopathy. Removing all or part of the vitreous vitrectomy. Reattachment of the retina for retinal detachment, a complication of diabetic retinopathy.

Injection of medicines called corticosteroids. Other Eye Diseases. Keep your blood sugar levels in your target range as much as possible. Over time, high blood sugar not only damages blood vessels in your eyes, it can also affect the shape of your lenses and make your vision blurry.

Keep your blood pressure and cholesterol levels in your target range to lower your risk for eye diseases and vision loss.

Also good for your health in general! Quit smoking. Quitting lowers your risk for diabetes-related eye diseases and improves your health in many other ways too. Get active. Physical activity protects your eyes and helps you manage diabetes.

Get Your Eyes Checked Eye problems are common in people with diabetes, but treatments can be very effective. Your eye-care specialist will explain these to you.

You should get an eye exam once a year, unless your ophthalmologist or optometrist has suggested something different. The risk of vision loss can be greatly reduced with regular checks. Remember, you may not be aware of changes to your vision and many problems can be treated when caught early.

Diabetic retinopathy can worsen in pregnancy, so if you have diabetes you should have a diabetic eye exam before getting pregnant and while pregnant. During the eye exam, your eye-care provider uses a special magnifying instrument to look for any blood vessel damage at the back of your eye.

Eye exams are a safe and necessary part of your diabetes management. Contact your eye-care professional directly for an appointment or have your health-care provider refer you for an eye exam.

A diabetic eye exam may be covered by your provincial health plan at no cost to you. You can confirm this with your diabetes care provider or when making an appointment. Therefore, it is important to monitor the vitamin D levels in patients with diabetes, not only for the prevention of osteoporosis but also diabetic retinopathy.

Dark fish and fortified foods such as milk or cereals are important sources of vitamin D. It is worth mentioning that vitamin D in the eye is locally produced, activated and regulated.

In fact, the eye expresses all the enzymes involved in vitamin D 3 production [ 32 ]. This is important because 1α,dihydroxyvitamin D 3 inhibits angiogenesis and this effect is mediated by vitamin D receptors, which are also essential during retinal vascular development [ 33 ].

Vitamin A is essential in visual processes and is a main component of rhodopsin. So, the regular consumption of foods high in vitamin A or carotenoid precursors, such as kale, spinach, broccoli, carrots or sweet potatoes, is recommended. Vitamin B 1 is also a potent free radical scavenger that prevents activation of the polyol pathway.

Fortified breakfast cereals are an important source of vitamin B 1. Finally, vitamin C ascorbic acid is also involved as a protective factor against diabetic retinopathy development. Vitamin C has antioxidant and anti-angiogenic actions and improves endothelial function.

In , we reported that patients with PDR presented lower intravitreous levels of ascorbic acid than non-diabetic individuals [ 34 ], which was confirmed more recently by other authors [ 35 ].

This is because ascorbic acid and glucose compete to use GLUT-1 to reach the retina and, therefore, the higher the glucose levels, the lower the uptake of ascorbic acid by the retina.

So, apart from recommending a regular consumption of foods with high content of vitamin C, such as citrus fruits, good glycaemic control is also essential to maintain correct intraretinal levels of ascorbic acid. Another factor related to lifestyle is tobacco smoking. There is controversial evidence regarding smoking as a risk factor for the development or progression of diabetic retinopathy.

Notably, a recent study found an association between smoking habit and deleterious findings in angio-optical coherence tomography OCT in patients with no visible diabetic retinopathy, so in very early stages of the condition [ 36 ].

Although other studies have had conflicting results, this should not alter the message about the importance of smoking cessation.

As regards exercise, it has been reported that regular physical activity reduces the risk of developing diabetic retinopathy [ 37 ].

However, it should be underlined that individuals with PDR should avoid high-intensity aerobic and resistance exercise, and physical activities comprising Valsalva manoeuvres which increase systolic blood pressure.

This is to reduce the risk of vitreous haemorrhage and retinal detachment. Specific sports such as boxing, high altitude mountaineering and scuba diving should also be avoided in individuals with PDR.

Another potential risk factor for developing diabetic retinopathy is related to the deleterious effect of ultraviolet B radiation on retinal pigment epithelium. The underlying mechanism includes the accumulation of reactive oxygen species that can damage retinal blood vessels causing retinal capillary apoptosis, hypoxia and neovascularisation.

This evidence suggests that reduction in sunlight exposure could be a preventive strategy against diabetic retinopathy in people with diabetes, and opens up the possibility of testing sunglasses as a tool for this purpose in appropriate clinical trials.

The strong relationship between the reduction of HbA 1c and the beneficial effects on diabetic retinopathy has obscured the necessity of performing clinical trials investigating the specific effects of glucose-lowering drugs per se on diabetic retinopathy, independently of their effectiveness in reducing blood glucose levels.

Therefore, we do not have robust information on this issue. This is very different from the available information that we have regarding the effects of glucose-lowering drugs on cardiorenal events, which have been widely studied. For this reason, studies aimed at examining the specific role of glucose-lowering drugs on the development and progression of diabetic retinopathy are needed.

To the best of our knowledge only one clinical trial is currently ongoing to examine this issue. This is the FOCUS study NCT a Phase III randomised clinical trial which will look at the long-term effects of semaglutide on diabetic eye disease when compared with placebo.

A total of participants with type 2 diabetes will be included and the estimated study completion date is November The concept that neurodegeneration is an early event in the development of diabetic retinopathy, which antedates and participates in its pathogenesis, has led to neuroprotection as a potential therapeutic strategy to arrest the progression of the condition [ 3 ].

As is the case with the brain, retinal neurodegeneration is not an isolated neuronal process and relies on the complex impairment of all the components of the NVU: macro- and microglia, neurons and vascular components endothelial cells and pericytes.

Among these cells, the glial activation plays an essential role in linking neuronal damage with early vascular impairment, which comprises the breakdown of the blood—retinal barrier and, consequently, vascular leakage [ 39 ].

Treatment with these neurotrophic factors has prevented the development of diabetic retinopathy in experimental models. Dipeptidyl peptidase IV DPP-IV inhibitors have also provided beneficial effects on NVU [ 40 ].

Although the enhancement of intraretinal levels of GLP-1 seems a relevant mechanism accounting for the beneficial effects of DPP-IV inhibitors, the activation of other pathways related to DPP-IV inhibition cannot be ruled out.

In addition, the lower cost and higher stability of DPP-IV inhibitors in comparison with GLP-1, could mean they are excellent candidates for clinical development. Presynaptic proteins, which are crucial for neurotransmission and synaptic homeostasis, as well as proteins involved in axonal transport, are also downregulated in the diabetic retina [ 41 , 42 ].

Therefore, a replacement treatment or therapeutic strategies addressed to avoid the diabetes-induced intraretinal reduction of these neurotransmitters could exert beneficial effects. However, further research in this field is needed.

Another successful strategy has been to block the endothelin-1 receptors ETB-R and ETA-R. By blocking these receptors, bosentan administered using eye drops exerted a beneficial effect on both neurons blockade of ETB-R and microvasculature blockade of ETA-R , thus preventing retinal neurodegeneration and vascular leakage [ 43 ].

To the best of our knowledge, there are no drugs recommended by any scientific society aimed at targeting the NVU for treating the early stages of diabetic retinopathy. The usefulness of corticosteroids or non-steroidal anti-inflammatory drugs NSAIDs by topical route for treating diabetic macular oedema DME in humans have been reported [ 44 , 45 ].

However, a lack of effect in reducing retinal thickness after 1 year of topical administration of the NSAID nepafenac has also been reported in patients with non-central-involved DME [ 46 ]. Fenofibrate and calcium dobesilate two drugs administered orally have shown to be effective and safe for the treatment of diabetic retinopathy in several clinical trials [ 3 ], but they are not formally recommended in clinical guidelines.

It is worth mentioning that three large randomised clinical trials aimed at evaluating the effect of fenofibrate in arresting the progression of diabetic retinopathy are ongoing in the USA NCT , Australia NCT and UK Scotland; NCT These studies will provide new evidence on the usefulness and safety of fenofibrate for treating the early stages of diabetic retinopathy and could be helpful to cover the treatment gap that currently exists for early-stage diabetic retinopathy.

However, the long-term systemic administration of drugs has two main problems. First, they need to be able to cross the blood—retinal barrier, which could be a limiting factor to reach the retina at pharmacological concentrations.

Second, systemic adverse effects and potential pharmacological interferences with other drugs used for the treatment of diabetes and its comorbidities is also a drawback that needs to be considered.

In addition, the use of repeated intravitreal injections seems a strategy disproportionally aggressive for treating the early stages of diabetic retinopathy. For these reasons, topical treatment eye drops targeting the NVU has emerged as a new strategy for treating the early stages of the condition [ 2 , 3 ].

Although the results of this study were positive in terms of preventing the progression of neurodysfunction, there was no impact on microvascular damage [ 47 ]. This could be attributed to the high proportion of participants included in the study with no or very mild microvascular disease, the excellent metabolic control throughout the study and the short follow-up 2 years.

Thus, neurodysfunction or neurodegeneration are not always the first abnormalities that occur in early stages of diabetic retinopathy. This finding underlines the need to incorporate the assessment of NVU integrity for identifying those patients in whom neuroprotective treatment might be of higher benefit Fig.

Therefore, methods for the assessment of neurodysfunction, such as microperimetry or flicker electroretinogram ERG handheld recording device RETeval , or methods such as OCT allowing the assessment of structural damage e.

neuroretinal thinning , should be included in the screening of diabetic retinopathy [ 40 ]. In addition, angio-OCT and ultra-wide field fundus fluorescein angiography FFA will improve our understanding of microvascular impairment.

These examinations could be performed even when there are no visible lesions in fundoscopic examination. It seems clear that the development and implementation of this new and more complex screening will depend on the appearance in the market of effective and safe drugs for treating early-stage diabetic retinopathy.

In this regard, clinical trials of drugs with experimental effectiveness in preventing both neurodegeneration and vascular leakage, such as GLP-1, DPP-IV inhibitors or endothelin blockers, are needed [ 2 , 3 ].

In the meantime, given the high risk of cardiovascular disease and dementia that is present among the type 2 diabetic population with diabetic retinopathy, the better phenotyping of this condition will permit us to identify individuals more prone to developing either cardiovascular events or cognitive impairment [ 48 , 49 ].

In the early stages of diabetic retinopathy, even before microvascular abnormalities can be detected in funduscopic examination, NVU impairment is already present in a significant proportion of patients. The main hallmarks of this diabetes-induced NVU impairment are: glial activation also named reactive gliosis , neuron apoptosis and vascular leakage due to the disruption of the blood—retinal barrier.

This information would be important for predicting the risk of cardiovascular events and cognitive decline, as well as to select the most appropriate treatment for the early stages of diabetic retinopathy, when such treatments are available.

DR, diabetic retinopathy; GFAP, glial fibrillary acidic protein; IF, immunofluorescence. In summary, apart from controlling modifiable risk factors, the early identification of patients with diabetes with NVU impairment could revolutionise the current management of diabetic retinopathy see Summary Text box.

Robert Levine Charitable Foundation has been created to change the evaluation and grading of diabetic retinopathy based on this new evidence [ 50 ]. This initiative would be the beginning of a new era in the diagnosis and treatment of diabetic retinopathy, thus allowing better phenotyping and, consequently, a more personalised and cost-effectiveness treatment.

Diabetic retinopathy prevention -

Diabetes damages blood vessels all over the body. The damage to your eyes starts when sugar blocks the tiny blood vessels that go to your retina, causing them to leak fluid or bleed.

These new blood vessels can leak or bleed easily. Eye doctors can check for diabetic retinopathy as part of a dilated eye exam. The exam is simple and painless — your doctor will give you some eye drops to dilate widen your pupil and then check your eyes for diabetic retinopathy and other eye problems.

If you do develop diabetic retinopathy, early treatment can stop the damage and prevent blindness. If your eye doctor thinks you may have severe diabetic retinopathy or DME, they may do a test called a fluorescein angiogram. This test lets the doctor see pictures of the blood vessels in your retina.

Managing your diabetes is the best way to lower your risk of diabetic retinopathy. That means keeping your blood sugar levels in a healthy range. This test shows your average blood sugar level over the past 3 months. You can work with your doctor to set a personal A1C goal.

Meeting your A1C goal can help prevent or manage diabetic retinopathy. Having high blood pressure or high cholesterol along with diabetes increases your risk for diabetic retinopathy.

So controlling your blood pressure and cholesterol can also help lower your risk for vision loss. In the early stages of diabetic retinopathy, your eye doctor will probably just keep track of how your eyes are doing. Some people with diabetic retinopathy may need a comprehensive dilated eye exam as often as every 2 to 4 months.

Medicines called anti-VEGF drugs can slow down or reverse diabetic retinopathy. Other medicines, called corticosteroids, can also help. Learn more about injections. Laser treatment. To reduce swelling in your retina, eye doctors can use lasers to make the blood vessels shrink and stop leaking.

Learn more about laser treatment for diabetic retinopathy. Eye surgery. If your retina is bleeding a lot or you have a lot of scars in your eye, your eye doctor may recommend a type of surgery called a vitrectomy. Learn more about vitrectomy.

Scientists are studying better ways to find, treat, and prevent vision loss in people with diabetes. One NIH-funded research team is studying whether a cholesterol medicine called fenofibrate can stop diabetic retinopathy from getting worse.

With blood glucose sugar control, regular eye exams and early treatment, the risk or worsening of eye damage can be reduced.

Having too much sugar in your blood can damage the blood vessels in the part of the eye called the retina. The retina is the tissue lining the back of the eye. High sugar levels cause the blood vessels to swell and leak into the retina and cause blurred vision or blind spots. If left untreated, new blood vessels may grow and cause further damage to your vision.

All people with diabetes both type 1 and type 2 are at risk for diabetic retinopathy. Diabetic retinopathy develops over time and often goes unnoticed until vision loss occurs. Following your diabetes ABCDEs and getting your eyes checked regularly by an ophthalmologist or optometrist are crucial to prevent vision loss or keep it from getting worse.

If you have diabetic retinopathy, very effective treatments are available. Your eye-care specialist will explain these to you. You should get an eye exam once a year, unless your ophthalmologist or optometrist has suggested something different. The risk of vision loss can be greatly reduced with regular checks.

Remember, you may not be aware of changes to your vision and many problems can be treated when caught early. Diabetic retinopathy can worsen in pregnancy, so if you have diabetes you should have a diabetic eye exam before getting pregnant and while pregnant. During the eye exam, your eye-care provider uses a special magnifying instrument to look for any blood vessel damage at the back of your eye.
