A posterior vitreous detachment (PVD) is a condition of the eye in which the vitreous membrane separates from the retina. [1] It refers to the separation of the posterior hyaloid membrane from the retina anywhere posterior to the vitreous base (a 3–4 mm wide attachment to the ora serrata ).
Cataract surgery: Previous cataract surgery, particularly when associated with vitreous loss, is linked to shifts in the vitreous, increasing the risk of posterior vitreous detachment. [7] [9] [17] Inflammation: Inflammatory eye conditions, such as uveitis, are associated with an increased risk of posterior vitreous detachment. [7] [9]
Posterior capsular rupture, a tear in the posterior capsule of the natural lens, is the most-common complication during cataract surgery. [8] Posterior capsule rupture can cause lens fragments to be retained, corneal oedema, and cystoid macular oedema; it is also associated with increased risk of endophthalmitis and retinal detachment.
Epiretinal membrane or macular pucker is a disease of the eye in response to changes in the vitreous humor or more rarely, diabetes.Sometimes, as a result of immune system response to protect the retina, cells converge in the macular area as the vitreous ages and pulls away in posterior vitreous detachment (PVD).
Posterior capsular rupture, a tear in the posterior capsule of the natural lens, is the most-common complication during cataract surgery. [21] Posterior capsule rupture can cause lens fragments to be retained, corneal oedema, and cystoid macular oedema; it is also associated with increased risk of endophthalmitis and retinal detachment. [21] [23]
Posterior capsular rupture, a tear in the posterior membrane of the natural lens capsule, is the most common complication during cataract surgery, with its rate ranging from 0.5% to 5.2%. [2] In most cases the situation can be salvaged, though it may be necessary to modify the original plans for the placement, refractive strength, and type of ...
Predisposing factors for Postoperative PVR are preoperative PVR, aphakia, high levels of vitreous proteins, [5] duration of retinal detachment before corrective surgery, the size of the retinal hole or tear, intra-ocular inflammation, vitreous hemorrhage, and trauma to the eye. An equation to calculate the patient's risk for acquiring PVR is:
Pharmacologic vitreolysis is an improvement over invasive surgery as it induces complete separation, creates a more physiologic state of the vitreomacular interface, prevents the development of fibrovascular membranes, is less traumatic to the vitreous, and is potentially prophylactic.
