What is Retina?
The retina is a sensory layer at the back of the eye that provides visual function. The retina, which perceives light and sends visual signals to the brain, processes the light coming through the cornea and lens in the eye and forms the final stage of the visual process. The retina is covered with nerve cells and billions of visual cells.
Retinal Disease Symptoms
Although the symptoms of retinal diseases vary depending on the type of the disease, symptoms such as blurred vision, loss of vision, flashes of light, fly swatting, red discharge and distorted vision are common. These symptoms may indicate serious retinal problems such as retinal tear, retinal detachment, macular hole and yellow spot disease.
Common Retinal Diseases
- Retinal Detachment: Detachment of the retina as a result of retinal tear; requires emergency treatment.
- Diabetic Retinopathy: It occurs as a result of damage to the blood vessels in the retina due to diabetes.
- Macular Hole: It is the formation of a hole in the macula located in the centre of the retina.
- Age Related Macular Degeneration: It is a disease that usually occurs with age and affects central vision.
Retinal Detachment Symptoms
In retinal detachment, patients experience visual disturbances such as flashes of light and sudden fly swings. If retinal detachment occurs, laser treatment can be effective in early intervention; however, surgical treatment may be required in some cases.
What is Retinal Surgery (Vitrectomy)?
Retinal surgery or vitrectomy is a procedure to repair damage to the retina by removing the vitreous gel. It is usually preferred in the treatment of problems such as retinal detachment, diabetic retinopathy, retinal haemorrhage or macular hole.
Things to Consider Before and After Retinal Surgery (Vitrectomy)
Before the operation, the doctor's instructions should be followed, the patient should be on an empty stomach and blood thinners should be reported to the doctor. After the surgery, eye drops should be used to prevent infection, glasses should be worn to protect the eye and physical activities should be restricted. The healing process may differ from patient to patient, so it is important to follow the doctor's recommendations.
