Treatment for Floaters | What is Vitrectomy or FOV?


Published on

This is the presentation for the webinar I published on April 12, 2015. The webinar was focused on the treatment of floaters by 25 gauge vitrectomy. This eye operation is also called FOV, aka floaters only vitrectomy.

The slideshow discusses the process of vitrectomy, preoperative eye exam, the vitrectomy, post-operative expectations and follow up for those patients experiencing floaters in their vision.

I also included a video of an actual 25 gauge vitrectomy to remove floaters.

Please visit for more information.

I hope this is helpful.

Treatment for Floaters | What is Vitrectomy or FOV?

  1. 1. The Process of Vitrectomy Treatment for Floaters Randall V. Wong, M.D. Webinar, April 2015
  2. 2. Randall Wong, M.D.  Retina Specialist  Fairfax, Virginia, U.S.A.  20 Minutes from Washington, D.C. 
  3. 3. Characteristics of Floaters Size, Shape, Color of the vitreous floaters usually have no clinical significance. The most important feature about the “floaters” is whether or not they move “to and fro” with eye movement. By definition, what ever you are seeing must be located within the vitreous.
  4. 4. Vitreous Floaters “Floaters” exist only in the vitreous Removing the vitreous should be therapeutic. “Vitrectomy” is the eye operation to remove the vitreous…and the floaters
  5. 5. Types of Floaters Blood Inflammatory Cells Debris associated with Retinal Tear Asteroid Hyalosis Opacities in the Vitreous
  6. 6. Initial Consultation Vision Pressure Slit Lamp Examination Dilated Exam Cataract? PVD? Purpose: Assess overall health of your eyes
  7. 7. Initial Consultation The exam is not focused (pardon the pun) on confirming the presence of floaters. This is drastically different than most eye exams you have had. The Reason?
  8. 8. Cataract Cataract formation may occur but is unexpected. Pre-existing cataracts? Remember: Everyone develops cataracts in their life…everyone (with or without FOV/vitrectomy)
  9. 9. Major Risks of Vitrectomy (FOV) Blindness from infection is called endophthalmitis. Retinal detachments can also occur and can potentially cause blindness or significant loss of vision. Cataracts?
  10. 10. Hypotony Though 25 gauge is technically “sutureless,” in certain situations, I may consider to use sutures (stitches) to close the sclerotomies. This should reduce the chance of hypotony the first day after surgery. Hypotony is never expected later than the first day after surgery.
  11. 11. Vitrectomy 3 port, 25 gauge trans pars plana vitrectomy 3 ports (standard) 25 gauge – thin enough to be sutureless Pars Plana – safe place in the eye to insert trocars “Trans Pars Plana” = through the pars plana

  13. 13. PVD Posterior Vitreous Detachment allows more efficient removal of the vitreous. Posterior Vitreous Detachment does not always cause floaters. In fact, everyone will get a PVD as we age, yet most people do NOT notice floaters.
  14. 14. Posterior Vitreous Detachment Weiss Ring Posterior vs. Anterior Retinal Tears
  15. 15. End of Operation Look for tears in the peripheral retina Sutures, if needed Injection of Antibiotics/Steroid Dilating Drops Ointment and Patch
  16. 16. After the Operation Return home – outpatient surgery Relax, Eat Patch stays on Pain and discomfort is not anticipated Phone call
  17. 17. First Post-Operative Day POD#1 Patch removed Check Vision Check Pressure Examine Retina Drops Activity
  18. 18. Follow Up Full activity 24-48 hours in most cases. No gas is used. May leave when you are comfortable. First follow up appointment with me or your doctor within the first 7 to 10 days.
