David,

I’d like to reproduce at least part of your blog about Avastin vs Lucentis on my blog.

I have written extensively on this subject with over 30 posts.

Take a look, Irv Arons’ Journal:

Vision loss occurs as a result of the amount of edema. Depending on the location and extend of the BRVO there can be a range of edema at the fovea. It can also be related to secondary ischemia.

The primary issue with posterior segment surgeries and IOL calcuations is to make the proper correction in ultrasound velocity for individuals who have silicone oil in place. The velocity varies depending on the type of oil used. Unless this correction is made during IOL calculation, there can be siginficant power errors. Scleral buckles, especially cirucumfrencial ones can effectively lengthen the eye, and the axial length will thus be longer on A-scan. If a patient has a tractional RD affecting the fovea, it can effectively shorten the axial length since the retina is not lying flat on the sclera. In cases of vitrectomies without silicone oil, there is no effect on IOL power calculations.
