VANCOUVER, British Columbia Patients treated under extended
anti-VEGF dosing protocols for choroidal neovascularization due to age-related
macular degeneration may be more likely to lose visual acuity.

"Office examinations less frequent than every 4 to 6 weeks combined with
extended therapy should be used with caution, especially in eyes with good
visual acuities after the induction phase," John T. Thompson, MD, said here at
the American Society of Retina Specialists annual meeting.
In a retrospective analysis of 165 consecutive treatment-naïve
patients treated by Dr. Thompson at his clinic with Lucentis (ranibizumab,
Genentech) or Avastin (bevacizumab, Genentech), recurrent choroidal
neovascularization frequently was associated with decreased vision during
extended dosing.
