The retina is the light-sensitive tissue lining the inner surface of the eye. It receives visual images and converts them into nerve impulses for the brain to perceive as vision.
Retinopathy is disease of the retina. It typically involves damage of small blood vessels that nourish the retina.
Retinopathy can have different causes but the 2 most common are diabetes and hypertension.
In hypertension, persistent high blood pressures weaken small blood vessels everywhere in the body, including the eyes. Some patients may not be aware that they have hypertension until visual symptoms due to retinopathy develop.
Diabetes is by far the most common cause of retinopathy. High blood sugar levels can damage blood vessels of the retina just like any other blood vessels. Diabetic retinopathy can be non-proliferative or proliferative.
In the early, non-proliferative stage, weakened spots on blood vessels may bulge, forming tiny aneurysms. These aneurysms can bleed or leak fluid into the retina. When this happens, patient may see floating spots or strings. Some patients may experience eye pain or redness, while others may have no symptoms at this stage. Leaking of fluid into the central area of the retina - the macula - results in macular edema, which may cause blurry vision, or double vision.
Patients may also present with small white patches on the retina. These so-called cotton-wool spots correspond to areas of poor blood supply.
As retinopathy progresses, new, abnormal blood vessels begin to grow in an attempt to compensate for the inadequate blood supply. This advanced stage is known as proliferative retinopathy. The abnormal blood vessels may grow and bleed into the vitreous - the gel-like structure that fills the space between the lens and the retina. Depending on the amount of bleeding, patients may see small dark spots, or experience cloudy vision or temporary loss of total vision.
Abnormal blood vessels may cause scar formation and detachment of the retina. They may also block the normal flow of fluid, causing pressure to build up in the eye, ultimately resulting in peripheral vision loss, in a condition known as glaucoma. Left untreated, complications of retinopathy will eventually lead to partial or total loss of vision.
Retinopathy can be diagnosed with a comprehensive eye exam with pupil dilation. Early diagnosis is crucial to prevent blindness. People with diabetes or hypertension are advised to have their eyes examined at least annually.
Treatment of non-proliferative retinopathy is typically directed at the cause. For most patients, this means control of blood sugar and/or blood pressure, which can help slow or stop progression of retinal damage.
Proliferative retinopathy requires prompt treatment in the eye to prevent vision loss. Treatment options include:
- Medications, which act to stop the growth of new blood vessels and decrease fluid buildup. These medications are typically injected into the vitreous.
- Photocoagulation, also called focal laser treatment, in which laser beams are used to seal the leakage from the abnormal blood vessels.
- Pan-retinal photocoagulation, or scatter laser treatment, where laser beams are used to shrink the abnormal blood vessels.
- And vitrectomy, a surgical procedure in which the damaged vitreous is removed and replaced with a new fluid.
Great channel love the videos, please make more cardiology videos it would be really great and benefit civilians with standard heart knowledge. It would also benefit learning.
A large amount of knowledge consised in a small video ❣️
Very informative and brief
Thank you a lot!
Night before my optha exam, I'm woefully ill prepared but this really helped!! Will be able to write something now at least
How did it go?
My Dad has retinopathy. Great to learn about it.
Simple + nicely explained
Always clear 👌 I don't have enough knowledge in science to be sure of the informations given in this channel but at least it is very clear and interesting 👍
Very pithy and clear presentation
Many thanks for this video. It would be pertinent to add that diabetic retinopathy may be asymptomatic if the macula is spared.
Thanks for the info.
Helpful thank you 🙏🏼
Excellent
Thank u so much
Thanks
So amazing video
May god bless you
thankyou
Thank you for simple way presentation
السلام عليكم هل يوجد شرح لمواد الطب سنه اولى سواء بالعربي او انجليزي في هذه القناة اذا لا يوجد هل تعرف قناة تساعدني في ذلك ارجو الرد and thankyou
can these 2:07 black spots go away?
What is best breakfast for diabetics?
The Carnivore Diet
What is Retinopathy?
Retina disease
So, are floaters that people see are caused by aneurysms in the eyes?
Yes
can those black spots go away?
@@saekisadako2118probably needs surgery as soon possible,can be irreversible damage if not cured! Can you let know whats happened,or was the outcome
@@atilondon my doctor checked my eyes ( visual evoke potential, oct retinography etc) he said there is no damage but i had hemorrages. could it be merely droplets of blood that block parts of my vision?
👁
I have had a black tadpole like thing go across my eye. A few times before but it went away . Now i don't have that any more. 👀But my dog does. 🐕🦺🧑🦯 Kidding We both see everything fine. 😎🤓Oh she is a bear ? 💜 My friend can't she to good ! All she can see is dollar signs when she looks at me.? 🤑😉😄
