Using avastin (bevacizumab) for macula degeneration treatment?

Using avastin (bevacizumab) for macula degeneration treatment?

Avastin (bevacizumab): Avastin (bevacizumab) is a drug that is commonly used in the treatment of wet macular degeneration and other eye conditions involving leakage of fluid from blood vessels in the retina. ...Read more

Does symptomatic (floaters) lattice degeneration require prophylactic laser treatment? Does it minimise the risk of potential future tractional tears?

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

Eccimery laserfor miopia in glaucoma patient?

Not recommended: Laser refractive surgery is generally not recommended for patients with glaucoma but it depends on many factors: is it early glaucoma, is prk planned? There may be exceptions to the general rule. ...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

How effective is the new laser cataract surgery?

How effective is the new laser cataract surgery?

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 more

In glaucoma is trabectome surgery similar to slt laser treatment?

In glaucoma is trabectome surgery similar to slt laser treatment?

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 more

What is the outcome of yag laser iridotomy?

What is the outcome of yag laser iridotomy?

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

Does doing a laser retinopexy around areas of lattice degeneration reduce the risk of tractional tears ensuing from posterior vitreous detachment?

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

How can the shot of avastin (bevacizumab) in eye complication treatment work?

How can  the shot of avastin (bevacizumab) in eye complication treatment work?

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?

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 more

Any operation for macular puckering?

Any operation for macular puckering?

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 more

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

Which is more effective: Avastin (bevacizumab) or Erbitux?

Which is more effective: Avastin (bevacizumab)  or Erbitux?

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
