What is a pars plana vitrectomy mean?
Overview. Pars plana vitrectomy (PPV) is a commonly employed technique in vitreoretinal surgery that enables access to the posterior segment for treating conditions such as retinal detachments, vitreous hemorrhage, endophthalmitis, and macular holes in a controlled, closed system.
When was the first retina surgery?
The first operation attempted for treatment of retinal detachment was by James Ware in 1805 who drained the subretinal fluid by puncturing the sclera with a knife [16].
What is vitreo retina?
Vitreoretinal diseases are conditions that affect structures in the eye called the retina and the vitreous. The retina is the light-sensitive layer in the back of the eye that focuses images and transmits that information to the brain via the optic nerve.
Who invented retina surgery?
Inventor of the surgical treatment for retinal detachment. Surv Ophthalmol. Nov-Dec 1976;21(3):276-84.
Who invented vitrectomy?
Robert Machemer, the inventor of modern vitrectomy more than two decades ago, might scarcely recognize the procedure he invented.
What causes vitreoretinal disease?
A vitreoretinal disease may occur secondary to diabetes or another health problem. Conversely, aging may be the primary risk factor for some people affected by vitreoretinal disease. Examples of conditions categorized as vitreoretinal diseases include: Macular degeneration.
What is the difference between medical retina and vitreoretinal?
A retina specialist is a medical doctor who has specialized in ophthalmology and sub-specialized in diseases and surgery of the vitreous body of the eye and the retina. This subspecialty is sometimes known as vitreoretinal medicine. Retina specialists are highly trained.
Who invented scleral buckle?
In the USA, scleral buckling was also being developed by Charles Schepens, who deployed a polyethylene encircling tube and drained subretinal fluid along with diathermy [20,21,22,23,24].
How many types of vitrectomy are there?
There are 2 types of vitrectomy, based on the approach used to remove the vitreous gel; namely anterior and posterior vitrectomy. The most common approach is the posterior or pars plana vitrectomy performed as mentioned previously in order to enable certain procedures to be done at the back of the eye.
What does vitreo retinal mean?
Vitreo-retinal conditions. The term “vitreoretinal” refers to any operation to treat eye problems involving the retina, macula, and vitreous fluid. These include retinal detachment, macular hole, epiretinal membrane and complications related to diabetic retinopathy.
What material is a scleral buckle made of?
Silicone material stitched to the outside of the eye indents (buckles) the sclera, causing a slight decrease in the circumference of the eye. A scleral buckle is sometimes used in the management of retinal detachment.
