Hello and welcome to the zero to finals podcast.

My name is Tom and in this episode I'm going to be talking to you about retinal detachment.

And you can find written notes on this topic at zero to finals.com slash retinal detachment

or in the ophthalmology section of the second edition of the zero to finals medicine book.

And you can find flashcards and questions to train your knowledge

and help you remember the information for longer at members.0tofinals.com.

So let's get straight into it.

Retinal detachment involves the neurosensory layer of the retina, which contains the photoreceptors

and the nerves, separating from the retinal pigment epithelium, which is the base layer which

is attached to the corroid. Retinal detachment is usually due to a retinal tear,

allowing vitreous fluid to get under the neurosensory retina

and fill the space between the layers.

The neurosensory retina relies on the blood vessels from the corroid

for its blood supply.

Therefore, retinal detachment can disrupt the blood supply and cause permanent damage to

the photoreceptors, making the condition sight-threatening.

Let's go through the risk factors. The risk factors for retinal detachment are lattice

degeneration, which is thinning of the retina, posterior vitreous detachment, trauma to the eye,

diabetic retinopathy, retinol malignancy, and a family history. Let's talk about the presentation.

Retinal Detachment is a painless condition that can present with peripheral vision loss,

which is often sudden and described as a shadow coming across the vision,

blurred or distorted vision, and flashes and floaters.
