The retina plays an important role in our ability to see. It is a thin layer of light sensitive tissue at the back of the eye which sends images to the brain. If the retina is damaged or suffering from a medical issue it can cause visual impairment. Seeing a retina specialist in bethesda will help with early detection of problems and the correct treatment. Knowing the common retina issues, symptoms and treatments can help look after your long term eye health.
What Is The Retina And Why Is It Important?
The retina captures light and sends signals down the optic nerve to the brain. This allows us to identify objects, read, drive and see different colours.
As the retina is very important in allowing us to see clearly any damage can cause visual problems. There are many retina conditions that can develop slowly or cause sudden visual changes. Having regular eye exams will help detect issues early.
Common Retina Conditions
There are many medical issues that can affect the retina. Each have different causes, symptoms and treatments.
Age Related Macular Degeneration (AMD)
Age related macular degeneration affects the macula. This is the centre of the retina and allows us to see detailed. It commonly occurs as we age and can cause problems with everyday tasks such as reading, driving and recognising faces.
There are 2 types of AMD; dry and wet. Dry AMD is a slow progressing condition caused by the macula becoming thin. Wet AMD is caused by abnormal blood vessels growing under the retina and leaking.
The type and stage of AMD will determine what treatment is needed. Dry AMD can be managed by having regular check ups, making lifestyle changes and taking certain supplements. Wet AMD is commonly treated with anti-VEGF injections to help reduce abnormal blood vessels.
Diabetic Retinopathy
Diabetic retinopathy is caused by high levels of sugar in the blood damaging the small blood vessels in the retina. Diabetics run a risk of developing this condition.
Whilst in the early stages there may not be any noticeable symptoms. As the condition progresses patients may begin to experience blurriness, black spots, floaters and visual impairment.
Treatments depend on how much damage has been done to the retina. These can include anti-VEGF injections, laser treatment and surgery in severe cases. Looking after blood sugar, blood pressure and cholesterol can help reduce the risk of further damage.
Retinal Detachment
Retinal detachment is a serious condition where the retina detaches from the tissue below. This means the retina can no longer receive oxygen and nutrients.
Common symptoms include sudden flashes of light, increased floaters, blurred vision and shadows.
Retinal detachment should be treated immediately. Treatment can include laser treatment, freezing (cryotherapy), pneumatic retinopexy, scleral buckle surgery or vitrectomy. This will depend on where the detachment is.
Macular Edema
Macular Edema is caused by the build up of fluid in the macula. This causes swelling in the centre of the eye and can cause trouble reading, recognising faces and seeing detail.
This can be caused by diabetes, retinal vein occlusion, inflammation or other eye issues.
Treatment can include anti-VEGF injections, steroid injections or laser treatment. Identifying the issue early can help reduce swelling.
Retinal Vein Occlusion
Retinal vein occlusion occurs when a vein carrying blood away from the retina becomes blocked. This causes blood and fluid to enter the retina.
Patients may experience sudden blurriness or loss of vision in one eye. Some may have no symptoms.
Treatments can include anti-VEGF injections, steroid injections and laser. Looking after any underlying health issues such as high blood pressure and diabetes can help reduce the risk.
How Are Retina Issues Diagnosed?
Getting an accurate diagnosis means our eye specialists can identify what type of issue you are suffering from and how severe it is. A full retina examination will be carried out which can include:
– Pupil Dilation – Eye drops used to widen the pupil to allow better examination of the retina.
– Optical Coherence Tomography (OCT) – This is a scan that produces detailed images of the retina. This helps identify any swelling and fluid.
– Fluorescein Angiography – A special dye is injected into the blood stream to allow identification of blood flow in the retinal vessels.
– Retinal photography – Pictures of the back of the eye are taken to help identify any changes.
This will help determine if any treatment is required.
Modern Treatments For Retina Issues
There has been lots of developments in treating retinas. Depending on the issue a specialist can offer many different treatments.
Anti-VEGF injections are commonly used to treat wet AMD, diabetic macular oedema and some vein issues. Laser can be used to seal leaking blood vessels. Surgery can be recommended to treat more serious issues such as retinal detachment and bleeding.
Treatment will depend on many factors including eye health, medical history and how severe the issue is. Regular follow up appointments can help monitor treatment.
Specialist Care For Your Retina
Not looking after any changes to your sight can cause some retina issues to progress and cause permanent damage. Having an eye exam at the right time can help identify any issues and give the correct treatment.
If you are experiencing flashes, floaters, blurriness or sudden vision changes it is important to seek professional help. Depending on your diagnosis your specialist may recommend medication, injections, laser or surgery to the retina.
Seeing an experienced retina eye surgery can help you understand what you are suffering from and what treatment is available. Early assessment and regular follow up can help protect your sight.
