Retinal detachment is an eye fixed disease caused by the discharge of a skinny layer within the eye called the retina. This condition is assessed as emergency and may cause permanent blindness if not treated immediately.
The eye’s retina is a crucial part that functions to process the sunshine captured by the attention . After being captured, the light is converted into electrical signals and transmitted to the brain. These signals are then processed in the brain and interpreted as images seen by the eye.
If the retina is detached from its position, of course vision will be disrupted. This visual impairment can occur partially or completely, depending on how much of the retina is separated. Retinal detachment can occur to anyone, especially people aged 50 years and over.
Symptoms of Retinal Ablation
Retinal detachment or retinal detachment does not cause pain. Vision loss can occur suddenly, or be preceded by a number of symptoms below:
- Black patches appear that appear to float in vision (floaters).
- Vision is blurred or obscured by a shadow like a curtain.
- The field of vision narrows.
- Flashes of light on vision (photopsia).
Causes of Retinal Ablation
Retinal detachment occurs when the eye’s retina is detached from blood vessels that deliver oxygen and nutrients. The following are 3 conditions that can cause the retina to detach:
- There is a small tear in the retina. This tear causes fluid in the middle of the eyeball (vitreous) to seep in and accumulate behind the retina. The accumulated liquid will make the entire retina layer detached from the base. In general, tears in the retina of the eye occur due to tissue changes as you age. People with minus eyes (nearsightedness) or who have had cataract surgery are also at risk of experiencing a tear in the retina.
- Vitreous fluid buildup without tears in the retina. This condition are often caused by injuries, tumors, inflammation, and degeneration .
- Scar tissue forms on the surface of the retina. This condition makes the retina interested and detached. This condition is more common in diabetics with blood glucose that’s not well controlled.
Risk Factors for Retinal Ablation
There are variety of things that increase an individual’s risk of developing detachment of the retina , including:
- Above 50 years old.
- Have experienced retinal detachment.
- Having a family member with the same disease.
- Have suffered a serious injury to the eye.
- Suffering from nearsightedness (myopia) is severe.
- Have had surgery on the eye, such as cataract surgery.
- Have suffered from diseases of the eye, such as inflammation of the middle layer of the eye (uveitis).
Diagnosis of Retinal Ablation
To determine the diagnosis of retinal detachment, the ophthalmologist will perform an ophthalmoscopy with a special instrument to view the inside of the eye. If the ophthalmoscopy cannot clearly observe the condition of the retina, for example due to bleeding in the eye, the doctor will perform an ultrasound of the eye.
Treatment of Retinal Ablation
Treatment of detachment of the retina varies counting on the patient’s condition. If the retina is torn or hollow but hasn’t begin , the ophthalmologist can apply the subsequent actions to enhance vision and stop the retina from escaping:
- Cryopexy. This procedure is completed by freezing the tear within the retina, in order that the retina remains attached to the attention wall.
- Laser therapy (photocoagulation). The laser beam will burn the tissue around the retinal tear. The laser will also help the retina stick.
If the retina is dislodged, the doctor will treat it with surgery or surgery. The type of surgery performed depends on the severity of the patient’s condition. These operations include:
- Pneumatic retinopexy. This procedure is done by injecting gas bubbles into the eye, which will press the retina back to its normal position. This procedure is chosen if only a small portion of the retina is removed.
- Vitrectomy. In vitrectomy, the doctor will remove vitreous fluid and tissue that attracts the retina. Then, a gas or silicon bubble will be injected into the eye to hold the retina in position. Over time, gas bubbles are going to be replaced naturally by body fluids.
- Scleral buckling. In this procedure, the doctor will place silicon from the surface of the white a part of the attention (sclera). This silicon will bring the eyeball closer to the retina, in order that the retina returns to its position. If the detachment condition is very severe, silicon will be placed around the eyes permanently. Even so, silicon will not block vision.
Prevention of Retinal Ablation
Retinal detachment is not always preventable. However, the risk of retinal detachment can be reduced through the following steps:
- Immediately see an eye doctor if floaters appear, flashes of light, or there are any changes in the visual field.
- Routinely check eyes at least once every year. Examination should be done more often if you have diabetes.
- Routine control of sugar levels and blood pressure, so that the condition of the retinal blood vessels remain healthy.
- Use eye protection when exercising or when doing activities that are at risk of injuring the eye.
