Question 1

symptoms of torn retina?

Accepted Answer

Flashes and floaters: Typically patients will note flashing lights particularly at night.  They may also note floating 'specks' in their vision caused by loose bits of the vitreous gel at the back of the eye.  Some may note a curtain over a peripheral part of the vision.  All these call for an immediate dilated eye exam by an ophthalmologist.

Question 2

what causes retina detachment?

Accepted Answer

Flashes floater veil: Vitreous separation ; traction on the retina causes retinal tears-causing vitreous floaters ; hazy vision.  Laser helps to prevent the tear from progressing to a retinal detachment as fluid flows though untreated tears and the retina falls off the back of your eye-like wallpaper coming off a wall.  This causes a veil in your side vision then central vision loss.  It is painless.

Question 3

will my retinas be damaged by mydriasis?

Accepted Answer

No: Mydriasis, or dilated pupils, can be caused by eyedrops administered at the doctor's office or as the result of disease or injury. Although the pupil helps to control the amount of light entering the eye, it affords little help in protecting the eye from the light. Sunglasses will help reduce the intensity of the light and will add another layer of protection against uv damage.

Question 4

how come a retina is completely detached?

Accepted Answer

Retinal detachments: The retina is permanently attached to the optic nerve and the ora serrata( the area in front of the retina). A total detachment means the retina between these attachments is separated from the lining under the retina(rpe). This can be from a tear that lets fluid under the retina (rhegmatogenous) or from fluid leaking under the retina (serous). Exceptions - giant retinal tears and on avulsion.

Question 5

what is the procedure that secures the retina?

Accepted Answer

Several: Laser retinopexy is the procedure used to treat holes and tears that are thought to be amendable to this treatment. Pneumo-retinopexy uses intraocular gas to tamponade superior retinal breaks. Retinal detachments are usually treated by surgical techniques involving retinal bands, buckels, sponges, cryoretinopexy, laser photocoagulation, intraocular gas, or silicone oil. All depends on complexity

Question 6

what is thin retina?

Accepted Answer

Retina: The retina is in the back of your eye, and apparently you may have had an exam or test done that states your retina was thin?  See eye dr. for follow-up visit.  Best wishes.

Question 7

what is scarring on the retina?

Accepted Answer

Retinopathy: Retina is the inner most layer of the eye that can be affected by uncontrolled  diabetes or uncontrolled hyigh blood pressure. These conditions can either lead to fragile new vessel development or the bleeding of the existing vessels. When these heal by either laser or by themselves , it usually leads to retinal scarring.Sometimes these scars can contract and lead to retinal detachment.

Question 8

when is cryo vs laser used on retina?

Accepted Answer

Visibility: Cryo and laser are used to reattach retinas and deal with bleeding.  Cryo is a little cruder but can be used when there is a lack of direct visibility.  It is applied outside the eye directed to the inside.  Laser requires a visible pathway, is more precise and is applied to the inside.  Your retinal surgeon will decide which is best for your problem.

Question 9

is an atrophic hole in your retina serious?

Accepted Answer

Usually not: Atrophic holes can be found in 2-5/100 people and are associated with lattice degeneration; however,  retinal detachments occur at a rate of one in 9, 000 (much less). Atrophic holes tend to remain stable and do not require treatment unless there is a history of retinal tear or detachment (in the fellow eye or in the family) most can generally be followed without treatment (laser treatment).

Question 10

what are the cones and rods in the retina for?

Accepted Answer

Light perception: The retina has 10 layers and the bottom layer is made up of the rods-that perceive light and dark and movement, and the cones-that perceive color.  Cones are mainly in our center vision and rods in the side vision.  Light hits the rods and cones (called photoreceptors) and they convert the light signals into electro-chemical signals that are transmitted to the brain.
