Retina detachment11/27/2023 ![]() ![]() Pars plana vitrectomy or PPV is currently the most popular method to remove fibrosis (if any is present) to repair the detachment.Scleral buckle surgery using silicone sponge.This will require proper positioning for several days to close the tear and wait for the leaky fluid to be reabsorbed. Pneumatic Retinopexy in conjunction with laser or cryotherapy may be necessary in certain cases.If the detachment is wide, laser treatment may not be enough. Laser Photocoagulation may only work on small affected area near the periphery.Treatment method depends on the nature and severity of the detachment and may require several types of treatment: After treatment, avoid any activities that may impact the affected eye for at least 1 – 2 weeks so that it can completely heal. An outpatient procedure can be performed without hospital stay. Retinal tear or hole can be treated with laser photocoagulation or cryotherapy around the tear to prevent fluid from leaking out. If the optometrist cannot observe the retina with standard equipment due to conditions like internal eye bleeding, ophthalmic ultrasound may be necessary to diagnose retinal detachment. If you experience another episode of abnormal vision or worsening condition, please consult your optometrist immediately. Once the iris has been dilated, patients may experience blurred vision and light sensitivity for 4 – 6 hours until the iris returns to normal. This is to make sure that there really is no tear or detachment. If tears or holes are not detected without any detachment, the next appointment will be within the next 1 – 2 weeks. After iris dilation, the optometrist will use special tools and lens to examine around the retina. If you experience any abnormal vision, it is best to consult an optometrist for a complete eye exam. Dark shadows like curtains that partially or completely block vision.Seeing many black floaters in the eye acutely.If the detachment advances, symptoms will be clearer. Some patients may not even notice in the beginning. Retinal detachment usually occurs acutely. Previous history of eye surgery, such as cataract or glaucoma treatment.History of retinal detachment in the other eye.If the vitreous gel leaks through the hole or tear and collects under the retina, it will cause retinal detachment. In some cases, the vitreous gel may collect quite a bit thereby causing retinal tear, particularly around the area with lattice degeneration, which often occurs in the peripheral area of the retina that can be easily torn. It usually does not cause any problems known as posterior vitreous detachment or PVD. As a person ages, the vitreous gel becomes more fluid causing shrinkage and detachment from the retina. RRD occurs when the fluid or vitreous gel leak under the retina. Exudative Retinal Detachment or ERD tends to be caused by inflammation, eye tumor, or eye trauma which lead to fluid leakage from the blood vessels that collect under the retina.It can also be found in patients with severe inflammation in the vitreous or retina or patients who had eye injury or rupture. It is not very common, but often found in diabetic patients with advanced diabetic retinopathy where abnormal blood vessels formed and bleeding occurs in the vitreous. Tractional Retinal Detachment or TRD occurs when the scar tissue or fibrosis pulls on the retinal surface causing it to detach from the eyeball.In this case, it is only mentioned because it is a common occurrence and requires immediate treatment. The tear or hole in the retina causes the vitreous fluid to leak under the retina leading to retinal detachment. Rhegmatogenous Retinal Detachment or RRD is the most common type.There are three types of retinal detachments: The affected area will be damaged permanently. If left untreated for a long time, the optic cells will degenerate and die due to lack of blood flow. If the retina does not receive enough nutrients and oxygen, it will not be able to function properly. ![]() Retinal detachment is a condition which the retina detaches from the back of the eyeball. Likewise, if the retina degenerates, our vision will be less sharp. If the film deteriorates, the picture will not be sharp. If we compare the eye to a camera, the retina is like the film. It consists of the cells detect light and millions of other optic nerves that convert light to signals sent to the brain so that we can see things. ![]() The retina is a thin layer of tissue on the back side of the eye.
