Depends on a lot: This is often the debate which engages forensic neuropsychologists (see http://forensicneuropsychology.Com) and forensic neurologists. Results can vary greatly even with similar ct or MRI findings. Generally severity, presence of intracranial bleeding, elevated icp, early or especially post-traumatic seizures, locaiton of injury, shearing, and pre-injury factors ie. Age, prior injury, health etc. ...Read moreSee 2 more doctor answers
Wouldnt pars plana vitrectomy reduce the risk of retinal tears or detachments due to vitreoretinal traction for someone with lattice and vitr degen?
Progressive macular pucker 20/30 vision, distortion & glaucoma. Visual fIeld good,nerve damage 30-45%.Would vitrectomy cause glaucoma to progress?
Possible: Vitrectomy and glaucoma may have an association. It is suspected that glaucoma occurs more often in patients who have had vitrectomy and subsequent cataract surgery. An ongoing clinical trial is aimed to answer this question with more clarity. PROVE Study. http://www.aaojournal.org/article/S0161-6420(14)00344-3/references AND https://clinicaltrials.gov/ct2/show/NCT01162356 ...Read more
Same: Posterior vitreous detachment (PVD) occurs when the vitreous gel becomes more like a liquid. The solid component of the gel floats in the liquid component of the gel. This liquefaction process is basically vitreous "degeneration." the symptoms are floaters (black spots, cobwebs, bugs) and sometimes flashes of light. ...Read more
Does doing a laser retinopexy around areas of lattice degeneration reduce the risk of tractional tears ensuing from posterior vitreous detachment?
Yes,it should reduce: Yes, the decision for retinopexy is best made by retina subspecialist who can assess whether the degree of lattice ; or the presence of high risk thinning would warrant the risks. Retinopexy creates a tighter bonding so that in event of PVD there is lower likelihood of retinal tears. ...Read more
Why do post-cataract surgery retinal detachments occur? Is there some retinal pulling involved from posterior vitreous detachment (pvd)?
Destabilization: The natural lens and its supports stabilize the front of the eye and vitreous. Removal of the thick natural lens and substitution with a thin artificial lens, increases the chance for the vitreous to move in ways that can destabilize the attachments of the vitreous over the retina. If there are weak places, this can increase the chance of detachment, even in the best of cataract surgeries. ...Read moreSee 1 more doctor answer
Low risk procedure: A retinal tear can be surrounded by laser, which helps to prevent retinal detachment. One complication is that the treatment is not adequate, and a detachment happens anyway. There can be some discomfort during the laser procedure, but there is virtually no risk of inflammation, and no risk of infection. It is remotely possible that the laser could be applied to an unintended part of the retina. ...Read moreSee 1 more doctor answer
Not directly: A scleral buckle is a required element of retinal re-attachment surgery and will be done by your retinal surgeon if needed. It will alter the refraction but does not permanently damage the vision. Retinal detachment can do that but do not let that damage be blamed on the buckle. ...Read more
Does symptomatic (floaters) lattice degeneration require prophylactic laser treatment? Does it minimise the risk of potential future tractional tears?
Depends: Lattice degeneration is thinning of peripheral retina from vitreous "pulling" on retina with whitening of blood vessels- forms a patch of "lattice" white blood vessels and thinned retina. Lattice can be associated with round retinal holes from the thinning and retinal tears at the edge-this can result in retinal detachment. Laser is used to treat symptomatic tears or risk of retinal detachment. ...Read more
Can anyone tell me is vitreous detachment after a retinal detachment surgery risking another retinal detachment?
Unusual: Most retinal detachments are preceded by a vitreous detachment. There are some exception, however those are uncommon or rare. As such, it is unlikely to have a vitreous detachment following retinal re-attachment surgery. If there was no vitreous detachment prior to retina re-detachment surgeyr, and no vitrectomy was done, a vitreous detachment could occur with it's risks. ...Read more
Can anterior vitreous detachment occur before pvd? Does it reduce the retinal risks assoc with cataract surgery? Symptoms other than floaters?
Vitreous detachment: May occur at the level of the anterior retina adjacent to an area called the ora serrata. The vitreous may delaminate from the retina at any location, meaning either posterior or anterior at anytime either from trauma or idiopathic. If the vitreous is already detached from the retina, then the risks of a retinal detachment is theoretically reduced. ...Read moreSee 1 more doctor answer
Safe overall.: Retinal laser is used for diabetic retinopathy and for retinal tears most often. The treatments are usually safe and effective. Complications are rare though sometimes encountered. An errant laser can cause a black spot in the vision, but this is rare in experienced hands. Also rare are problems with the pupil dilating. The benefit of laser to patients should exceed the risks otherwise why do? ...Read moreSee 1 more doctor answer
Yes: The vitreous jelly that fills the eye and attaches to the back wall of the inside of the eye (the retina) will detach from the retina with age (posterior vitreous detachment). At that time or days/weeks later a retinal tear or detachment may or may not occur as well. The latter conditions require urgent treatment before blindness ensues. A vitreous detachment is not treated. ...Read moreSee 2 more doctor answers
Lattice degeneration: Is typically congenital or developmental. Lasik would not cause lattice. There are a variety of retinal holes but it would be uncommon for non-invasive ocular surgery to actually cause a hole. Retinal holes may worsen with surgery and should be evaluated by your retina specialist prior to ocular surgery. ...Read more
