The retina is the delicate layer of cells at the back of the eye that captures external light, sending it to the brain, enabling sight. The retina is normally attached to the wall of the eye. Retinal detachment is a separation of the retina from the wall of the eye, akin to wallpaper peeling off a wall. If untreated, this can lead to permanent loss of vision or blindness due to interruption of blood and oxygen supply.
Once retinal detachment occurs, retinal detachment surgery can be carried out to reattach the retina.
Retinal detachment often requires urgent treatment. In particular, retinal detachment with new symptoms of peripheral visual loss that has yet to affect the central vision (often called macula-on or macula-sparing retinal detachment) may require emergency same-day surgery.
About 1 in 10,000 people per year in the general adult population will develop retinal detachment. This risk increases with age (>50 years), significant short-sightedness, prior severe trauma, eye surgery and a history of previous retinal detachment in the patient or family.
There are 3 types of retinal detachment:
1. Rhegmatogenous retinal detachment
This is the most common type of retinal detachment. It can cause rapid loss of vision and often requires emergency surgery within 24 hours.
Rhegma in Greek means rupture or rent. A break in the retina occurs, most commonly either in the form of a retinal tear or hole. The break allows fluid that normally stays in front of the retina, to flow through the break behind the retina, leading to separation of the retina from the wall of the eye.
Causes of rhegmatogenous retinal detachment:
2. Tractional retinal detachment
This is due to scar tissue formation on the surface of the retina, which gradually contracts, pulling the retina off the wall of the eye in the absence of a retinal break.
Causes of tractional retinal detachment: Diabetes is the main cause.
3. Exudative retinal detachment.
This is due to blood vessels within the retina leaking fluid underneath the retina, and is the least common type of retinal detachment.
Causes of exudative retinal detachment: A range, including inflammation (uveitis).
Symptoms of retinal detachment include:
Some patients may not immediately notice a loss of peripheral or central vision if it occurs in their non-dominant seeing eye.
The key is early diagnosis and treatment by a retinal surgeon when the retinal detachment is limited to the peripheral retina before central vision is affected, known as macula-on or macula-sparing retinal detachment. Once central vision is involved, there is no treatment that can return vision completely back to normal.
It is thus important to have your eye examined urgently by a retinal surgeon within 24 hours of developing any sudden change or loss of vision.
Treatment depends on both the type of retinal detachment and age of the patient.
While retinal detachment surgery has risks just like any surgery, it is a bigger risk to leave retinal detachment untreated as it can lead to a complete and irreversible loss of vision. The risks associated with retinal detachment surgery include:
The success rate depends on a number of factors, including type and duration of retinal detachment. For the most common type of retinal detachment (rhegmatogenous), the UK national average among a large cohort of vitreoretinal surgeons in a research study of 4231 patients published in 2020 (Ferrara et al, American Journal of Ophthalmology. 2020 Sept) demonstrated a retinal reattachment success rate of 85-88%. At OCL Vision, our equivalent success rate is >90%, with a 0% infection rate.
