At JRYN Eye Clinic, we believe that protecting your vision starts with understanding how diabetes can affect your eyes. Diabetic retinopathy is a diabetes-related eye condition that can damage the blood vessels in the retina, the light-sensitive tissue at the back of the eye. Without timely detection and appropriate care, it may lead to vision loss.
What Is Diabetic Retinopathy?
Diabetic retinopathy develops when high blood sugar levels damage the small blood vessels in the retina. These blood vessels may leak fluid or blood, or become blocked, affecting the retina’s ability to function properly.
In the early stages, diabetic retinopathy may not cause noticeable symptoms. This is why regular eye examinations are important, even when your vision seems normal.
Common Symptoms to Watch For
As diabetic retinopathy progresses, some patients may experience:
- Blurred or fluctuating vision.
- Dark spots or floaters in the field of vision.
- Difficulty seeing at night.
- Changes in vision or, in advanced cases, sudden vision loss.
Important: Do not wait for symptoms before arranging an eye examination. Early diabetic retinopathy can be present without noticeable changes in vision.
Why Early Detection Matters
Regular retinal examinations allow eye specialists to identify diabetes-related changes before significant vision problems develop.
At JRYN Eye Clinic, we encourage patients with diabetes to include comprehensive eye care in their ongoing health routine. Detecting retinal changes early helps your ophthalmologist determine the appropriate treatment and monitoring plan.
How Is Diabetic Retinopathy Diagnosed?
During a retinal evaluation, your ophthalmologist may recommend:
1. Comprehensive dilated eye examination
The retina and optic nerve are examined for signs of diabetic damage, bleeding, swelling, or abnormal blood vessels.
2. Optical Coherence Tomography (OCT)
OCT provides detailed images of the retina and can help identify retinal swelling, including diabetic macular edema.
3. Retinal photography
Retinal photographs help document the condition of the retina and monitor changes over time.
4. Fluorescein angiography, when indicated
This examination may be used to evaluate retinal blood vessels, leakage, or areas of reduced blood flow when additional information is needed.
The tests recommended will depend on your symptoms, diabetes history, and retinal findings.
Treatment Options for Diabetic Retinopathy
Treatment depends on the stage of diabetic retinopathy and whether complications such as diabetic macular edema or abnormal blood vessel growth are present.
1. Regular Monitoring
For early-stage diabetic retinopathy, your ophthalmologist may recommend regular follow-up examinations to monitor retinal changes.
Managing blood sugar, blood pressure, and cholesterol with your healthcare team is also an important part of protecting eye health.
2. Anti-VEGF Injections
Anti-VEGF medications may be recommended for certain retinal conditions associated with diabetes, particularly diabetic macular edema and some cases of proliferative diabetic retinopathy.
These medications are administered by injection into the eye and may help reduce abnormal blood vessel growth or retinal swelling.
3. Retinal Laser Treatment
Laser treatment may be recommended for selected patients, particularly those with proliferative diabetic retinopathy or specific areas of retinal leakage.
The purpose of laser treatment is to address targeted retinal areas and reduce the risk of further complications. Suitability depends on the individual retinal condition.
4. Vitrectomy Surgery
In advanced cases, such as certain types of vitreous hemorrhage or tractional retinal detachment, vitrectomy surgery may be considered.
This procedure removes the vitreous gel from inside the eye and allows the retinal surgeon to address specific complications.
Who Should Have a Diabetic Eye Examination?
We recommend discussing retinal screening with your ophthalmologist if you:
- Have type 1 or type 2 diabetes.
- Have had diabetes for several years.
- Notice new floaters, blurred vision, or changes in your eyesight.
- Have been advised to undergo regular retinal monitoring.
- Are pregnant and have diabetes or have been diagnosed with gestational diabetes, as screening recommendations may differ.
Your recommended examination schedule will depend on your diabetes type, retinal findings, and overall health.
When Should You Seek Urgent Eye Care?
Please seek prompt ophthalmic evaluation if you experience:
- Sudden vision loss.
- A sudden increase in floaters.
- Flashes of light.
- A dark curtain or shadow across your vision.
These symptoms may indicate a retinal emergency and should not be ignored.
Why Choose JRYN Eye Clinic for Retinal Care?
At JRYN Eye Clinic, our approach to retinal care focuses on understanding each patient’s eye condition and selecting an appropriate diagnostic and treatment plan.
Our retinal specialist, Dr. Lee Jae Jung, is available for consultations related to retinal conditions, including diabetic retinopathy.
Through appropriate examination and follow-up, we aim to help patients understand their retinal health and make informed decisions about their eye care.
Protect Your Vision With Regular Retinal Checkups
Diabetic retinopathy can progress quietly, but early detection provides an opportunity for timely evaluation and management.
If you have diabetes, do not wait until your vision changes to schedule an eye examination. Regular retinal checkups and appropriate treatment can play an important role in maintaining eye health.
