Retina: Located near the optic nerve, the retina is a thin layer of tissue which overlays the back of the eye from the inside. The prime purpose of the retina is to receive light which is focused on the lens, then convert the light in neural signals, and then send these signals on to the brain for visual recognition.
As retina plays a vital role in vision, damage to it can cause permanent loss of vision. Ailments such as Retinal Detachment, in which the retina is unexpectedly detached from its natural place, can restrict the retina from accepting and processing light. Thus preventing the brain from obtaining this information and leading to blindness.
When the retina gets separated from the nerve tissues and also the blood supply underneath it, Retinal Detachment occurs. Retinal detachment can be treated but it must be taken care of very effectively otherwise in worst cases, it can lead to permanent loss of vision. Retinal detachment is a painless condition but it is usually seen having clouding effect like a grey curtain moving in front of eyes.
Diabetes can affect the other parts of body also. People who have Diabetes are more likely to have mild vision problems due to Diabetes. These problems can grow and start affecting vision. These people are likely to suffer from Diabetic Retinopathy, which can affect both eyes. This condition can be cured.
In some cases, high blood pressure can cause damage to the retina as well as the blood vessels of the retina. The retina's normal function can be disturbed because of this. If optic nerve experiences more pressure, the condition might lead to vision loss. This ailment is called hypertensive retinopathy (HR).
Age-related macular degeneration is also known as macular degeneration, AMD or ARMD. It is degradation of the macula. The macula is the little central region of the retina of the eye which is responsible for controlling visual acuity. The well-being of the macula defines our ability to recognize faces, read, drive, watch television, use devices, and perform any other visual chore that needs us to see fine detail.
The arteries and veins carry blood everywhere in our body, which also includes your eyes. The retina of the eye has one main artery and the main vein. When this main vein of the retina gets blocked, this condition is called the central retinal vein occlusion (CRVO). This blockage of vein results in spilling out of blood and fluids into the retina. CRVO is a common retinal vascular disorder.
The concept of CRAO is similar to CRVO; Central Retinal Artery Occlusion (CRAO) is the blockage of the main artery of the retina. It usually happens due to an embolus. CRAO causes sudden, unilateral, mostly painless, and typically severe vision loss.
Vitreous Haemorrhage is an eye condition when the blood leaks into the vitreous gel which is present in the eyes. This usually blocks and damages the blood vessels of the retina which results in blurred vision. The leaked fluid prevents the light that passes into the eyes. Many conditions can cause this eye problem. Vitreous haemorrhage can be removed with vitrectomy surgery, which may also be required to treat the cause of the haemorrhage.
Vitritis or Vitreous inflammation can occur due to many causes which include both infectious and non-infectious causes. This might also include autoimmune and rheumatologic processes. Vitritis is generally vision threatening and has severe sequelae. Today, there are various methods of treatment for Vitritis.
Central Serous Retinopathy (CSR), which is also called as Central Serous Chorioretinopathy (CSC or CSCR), is an eye condition which induces visual impairment, usually temporary, generally in one eye. CSR touches the central region of your retina, known as the macula. CSR can make your vision to be blurred and disfigured because of fluid collecting under your macula.
A retina specialist can figure out retinal detachment by doing some retinal and pupil response tests. These tests start from initial and simple visual acuity testing to advanced level ultrasound of the eye. The patient of retinal detachment starts getting the grey curtain in the vision at the inception stages of detachment process. Before the case gets worse, some symptoms and signs can be looked into to understand the beginning of retinal detachment.
The symptoms for retinal detachment are:
If you are facing any of the above mentioned, it is always safe to see a doctor in order to prevent further complications. Retinal Detachment should not be ignored. Severe cases of Retinal Detachment can lead to permanent loss of vision.
A proper retina treatment is necessary for retinal detachment. Retinal surgery is a proven and safest treatment for retinal detachment. It is also important to take the right a retina treatment as when it is detected. To ensure that retina treatment is effective, the patient should be treated with 24 hours in order to avoid the case going out of hands.
Retina treatment procedures include the following things:
Laser surgery repairs the tears in the retina which is the primary cause of detachment.
Cryopexy is the application of intense cold to underlying tissue which will cause scaring resulting in holding the retina intact in that place.
This procedure uses a tiny gas bubble which is placed inside the eye which brings the retina back in its place. It is generally followed by laser surgery to assure that the retina stays in the right place permanently.
Scleral buckle: It is the suturing of a silicone “buckle” into the eye which orders the wall of the eye into a place that admits the retina to reattach.
Don’t worry you are in safe hands. If you observe any slightest symptoms of this eye problem, please see the doctor as soon as possible. It may cost your eye sight if ignored.
