What percentage of patients develop epiretinal membrane or macular pucker after laser retinopexy (pascal) for treating lattice degeneration of retina?
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
Is there any current research showing successful treatment of CME/cystoid macular edema/ retinal edema with stem cells?
No: No this procedure should not damage the cornea but can cause some short term irritation of the cornea. ...Read more
In retinal detachment surgery, how far are we from finding a pharmacological cure for / preventative agent against proliferative vitreoretinopathy?
Decades if ever. Why: Because humans=Hi-Tech, medical system=Low-Tech & issues=complex. Study: https://en.wikipedia.org/wiki/Proliferative_vitreoretinopathy & http://goo.gl/Blh6rW & http://goo.gl/44sPmg for perspective. The pharma industry (crucial to many easy to use advances) looks for single molecules which interact with our fantastic complexity for more benefit than harm, though later always easier & more common. ...Read more
Good for parts: Laser assisted cataract surgery is just that. The new femtosecond laser helps make the incision part of cataract surgery more precise and predictable than traditional methods. The laser does not do the entire operation--only parts of it. There is a considerable extra expense to using the laser that is paid for by the patient. ...Read moreSee 4 more doctor answers
No: Trabectome surgery requires an incision to allow entry of a surgical instrument designed to electrically ablate tissue from the trabecular mesh work and aspirate it frame the eye. This is one of the more minimally invasive angle surgeries available. Slt is a laser procedure that incorporates a proprietary wavelength of laser light energy directed at the trabecular mesh work to stimulate outflow. ...Read moreSee 1 more doctor answer
Hole in the iris: This procedure is done in order to lower the risk of angle closure in patients with anatomically narrow angles. If the iris and the cornea are in close proximity they may touch and by doing so, block the drainage pathway of the eye. The hole made by the yag laser serves to provide a pathway for fluid to move between the front and back of the eye. ...Read more
What would be the reason to have prp laser on non-perfused peripheral retina.In crvo.? Ischemic.Already having lucentis (ranibizumab)..Could this affect va.
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
Anti-VEGF: Avastin (bevacizumab) is a chemically modified antibody that inactivates all forms of vascular endothelial growth factor, vegf. Vegf are chemical signals that cause blood vessels to leak lead in grow where they don't belong. Injecting Avastin (bevacizumab) to the eye helps to treat blinding conditions such as macular degeneration, diabetes, vein occlusions, retinopathy of prematurity & swelling from inflammation. ...Read more
Risk % of rd for someone with multiple lattice undergoing symptomatic posterior vitreous detachment? Prophylactic laser treatment recommended?
Careful: You are at increased risk for retinal detachment. I recommend being cautious with surgery for floaters. Wait at least one year before proceeding with surgery. If they still persist and are unbearable then consider surgery. Symptoms usually resolve or improve with time in 99% of the people. Consult with a retina specialist to determine if prophylactic laser is indicated. ...Read moreSee 1 more doctor answer
Vitrectomy: If the symptoms are severe enough, a retinal surgeon can perform a vitrectomy operation which involves delicately peeling the wrinkled membrane from the surface of the retina. Over time, this allows the retina to flatten out and assume a more normal shape. Cataract if a common complication of this operation. ...Read moreSee 2 more doctor answers
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.

Identical: Data on Bevacizumab or Erbitux in patients with metastatic colorectal cancer, patients who do not have a KRAS 12/13 gene mutation, have nearly identical survival rates. These identical results were seen after chemotherapy, where survival with chemo alone was about 5 months vs. 7-8 months using either bevacizumab (Avastin) or cetuximab (Erbitux). ...Read more
