What is proliferative Vitreoretinopathy?
What is proliferative Vitreoretinopathy?
Proliferative vitreoretinopathy is a disease process that follows the proliferation of ectopic cell sheets in the vitreous and/or periretinal area, causing periretinal membrane formation and traction, in patients with rhegmatogenous retinal detachments.
What is dialysis of the eye?
A retinal dialysis is a tear in the retina whose anterior edge is at the ora serrata and whose posterior edge is attached to the vitreous base. 1. The majority of patients presenting for surgical management of retinal dialysis are known to have a significant past history of trauma to the affected eye.
What is a Rhegmatogenous retinal detachment?
Rhegmatogenous detachments are caused by a hole or tear in the retina that allows fluid to pass through and collect underneath the retina, pulling the retina away from underlying tissues. The areas where the retina detaches lose their blood supply and stop working, causing you to lose vision.
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.
Can PVR be prevented?
In order to prevent PVR primarily, all patients with new-onset posterior vitreous detachments (PVDs), trauma, lattice degeneration or tears would need to be examined and all high-risk pathology would need to be treated.
How is PVR treated?
Currently, the only treatment option for PVR is retinal surgery. Vitrectomy is one form of surgery to remove scar tissue, fix holes in the center of the retina, or macula, and to remove the gel-like substance inside the eye (known as the vitreous).
Can rubbing eyes cause retinal detachment?
In general, eye rubbing alone will not lead to retinal tears or detachment. You would have to press and rub your eyes very hard to damage or detach the retina. However, excessive and aggressive eye rubbing is a bad habit that can potentially harm the cornea or cause eye irritation.
How can I strengthen my retina?
How to Improve the Health of the Retina
- Healthy and balanced diet.
- Avoiding unhealthy foods and drinks.
- Drinking plenty of water.
- Regular exercise.
- Wearing sunglass when out in the sun.
- Quitting smoking.
- Wearing eye protection.
- Regular eye check-up.
What are the signs of retinal dialysis secondary to trauma?
Other associated signs of retinal dialysis secondary to trauma include angle recession, traumatic cataract, vitreous hemorrhage, avulsion of the vitreous base, retinal demarcation lines, intraretinal macrocysts, and pars plana detachment [2].
How is a retinal detachment treated in dialysis?
An retinal dialysis with no or minimal subretinal fluid can be treated with photocoagulation or cryopexy [6]. A retinal detachment in the setting of a retinal dialysis should be treated within the same time period as other rhegmatogenous retinal detachments.
Is there recovery of renal function in dialysis dependent patients?
Although recovery of renal functions in dialysis dependent patients is estimated to be greater than 1%, there are no indicators that actually suggest such revival of renal function.
Which is the most common form of retinal dialysis?
Retinal dialysis has been described as the most common retinal sequelae from an ocular contusion injury [2-4]. Therefore, the diagnosis of a retinal dialysis is commonly associated with a history of ocular trauma, with the most common form being blunt injury with a fist.
