Retinal Detachment
The retina is a thin membrane that lines the back of the eye. It is the part of the eye that lets you see. Retinal detachment is the separation of the retina from the back of the eye.
Retinal detachment causes vision loss. There are two types of retinal detachment:
Partial. Partial retinal detachment is when only a part of the retina detaches from the back of the eye. A partial detachment usually causes some loss of side vision. Side vision is what you see just off to the side of what you are looking at. Rarely, it causes some loss of central vision. Central vision is what you see when you are looking at something. It is also what allows you to see focused, detailed images and color.
Complete. Complete retinal
Seeing floating specks or cobwebs (floaters) in front of your eye.
Seeing a black area in any part of your side vision.
Having fuzzy vision.
Seeing a floating empty circle in front of you.
DIAGNOSIS
You will be diagnosed by an eye specialist (ophthalmologist). To make a diagnosis, your ophthalmologist will make your pupils larger (dilation) and examine both your eyes.
TREATMENT
Treatment depends on the location, size, and nature of the retinal detachment. You may be treated with:
A laser. A laser may be the only treatment needed if only one area has detached and it is small.
Surgery. This may be done if the area that has detached is large. During the surgery fluid will be drained and a freezing probe will be used to create scar tissue. The scar tissue will help make the retina adhere to its underlying tissues once it flattens out.
Methods also exist which involve the injection of fluid or air into the vitreous cavity.
HOME CARE INSTRUCTIONS
Home care instruction should be given by the retina specialist depending on the type of detachment and the surgery or method that was used to treat it.

Loss of vision in one or both eyes
When the operation begins, Dr. Todd will use a steady hand to make a small opening in the side of the cornea. To begin removing the cataract, she switches tools and uses a vibrating ultrasound device to break the hard, cloudy lens into smaller pieces. Following this, she will suction the fragments out through the small cut in the eye. After the cataract is removed, she will begin to insert the intraocular lens in place. This is called an intraocular implantation. This lens is permanent, clear, and will restore normal vision for the patient.
Glaucoma is a disease of the eye and it is fluid pressure within the eye rises and if the eye is left untreated the patient might lose vision or maybe even blind. But this disease is generally affects both eyes but although one of their eyes may have more severe signs or symptoms then the other eye. When you have glaucoma there are small spaces in the front of the eye and they are called anterior chamber. There is clear liquid that flows in and out of the anterior chamber and the fluid nourishes and bathes nearby the tissues. And if the patient has glaucoma the fluid dose not drain like it should drain but the fluid drains out of the eye. And this may lead to fluid build up and pressure inside the rises of the eye. Unless the pressure is brought down and controlled and the optic nerves and some of the other parts of the eye might become damaged leading to ...
...eye fluid to leave the eye. The new channel helps to lower the eye pressure. Surgery will be recommended only if your ophthalmologist feels the benefit of a lower eye pressure achieved with an operation outweighs possible complications and/or further progression of optic nerve damage.
Retinitis pigmentosa is caused by damage to the retina of the eye. The retina is the light sensitive layer of tissue at the back of the eye. The retina focuses images in the brain and then sends them via electrical signals up to the brain. The retina is a very important part of the eye to help a person see. What is affected in the retina from this disorder are the rods in the eye. The rods allow a person to see in the dark. Retinitis pigmentosa slowly causes the rods in the eye to deteriorate over time. Retinitis pigmentosa also can cause the cones in people’s eyes to deteriorate. If a person’s cones deteriorate first, then the person first develops blindness in the center of their eye and they lose some of their color vision. This form of retinitis pigmentosa is much rarer than the form that deteriorates the rods in the eyes.
The high percentages of individuals who endure this impairment justifies and practically demands future research because the causes are not fully understood. The need for future research can be better emphasized if those with normal vision try to empathize with victims of macular degeneration. One can only imagine how frustrating it must be to receive sensatrions only in the periphery of the retina. Because the macula encompassed the cone rich fovea, which is used to focus on objects, the fovea degenerates as well. This occurence inables individuals to interpret the sensations they experience. Reading, ...
Laser therapy has been accepted widely by the general public and the medical professionals for its extensive benefits. This therapy precisely targets the affected area, minimizes the use of general anesthesia, encourages shorter hospital stay and improves the patient outcomes. These benefits have lead to its increased use and importance worldwide.
There is a very limited number in how this disease can be treated. I can be examined under anesthesia, specialized blood tests, CAT scans, and ultrasound (Finger, Pg. 1). Normally, a child would be examined if there were a past history of retinoblastoma from the parents. There would be a slim chance if a child shows up with the disease if the parents had ever had it. Normally, parents are the ones to notice the "white pupil" first (Ambramson, Ch6). The optometrist would recommend an ophthalmologist, who uses anesthesia to analyze the eye. He/she will then dilate the eyes to view the retina in search of tumors or abnormalities and where they are located. Sketches are then drawn or photographs using specialized equipment would be taken. Ultrasound would be used afterwards to determine the thickness and height if a tumor was found. Finally, a CAT scan is used to determine if the tumor is inside the eye or outside of their brain (Ambramson, Ch6). Once this is completed, the process of treatment would begin.
The laser procedure is much faster than the surgical operations. Moreover, regular visits are also not required to derive benefit of the treatment.
In checking for glaucoma, your doctor will want to know if any members of your family have had the illness. Then they will also ask whether you have noticed any recent changes in your peripheral vision. After asking about your family health history, your doctor will look for the symptoms of acute glaucoma.
This is a very rare complication wherein you may have loss of vision due to surgical complications.
Macular degeneration in general can affect many people in minor or drastic ways. People who experience this form often complain of vision loss when they are in dim light, especially when they are reading. The "dry" type is often characterized by a more gradual loss of vision compared to the "wet" type. Signs of this disease include an increase in drusen, which is an accumulation of a yellow-white substance, in the underside of the macular retina. A loss of cells can be seen in the macula. The macula is our sensitive sight region, where intricate detail can be seen. Thus, vision in this area is helpful and necessary to drive, read, focus on small details, and recognize familiar faces. The macula is located in the back of the eye known as the retina. The macula is only about 5 mm in diameter, and includes the fovea, which gives us our detailed central vision. If a person suffers from the "dry" form in one eye they will be more likely to develop it in the other eye as well.
Another eye disorder is farsightedness, also known as hyperopia. With this disorder, objects are seen clearly far away but are blurry close up. The eyeball is too short for the lens to focus a clear image on the retina. More than half of all people who wear glasses are farsighted. The signs and symptoms of farsightedness are aching or burning eyes, suffering from eyestrain, general tension, fatigue or headaches after close work, becoming irritable or nervous after prolonged concentration, and difficulty concentrating and maintaining a clear focus on near objects.
The images formed on the two retinas are so unlike that they cannot be blended in the brain. Thus, a double image is perceived. The condition is known as diplopia, or double vision. Prismatic lenses are prescribed to correct this defect.Imperfections in the cones of the retina, resulting from heredity or disease, cause defective color vision. This is known as color blindness, or Daltonism. In total color blindness, everything appears in shades of gray.
