Short answer is I recommend stopping the GLP-1 agonist if one eye has already developed NAION, for the sake of protecting the fellow eye. The fact is, our knowledge is still growing in this matter.

I have seen small amounts of PFO retained in the posterior pole and no inflammation was associated with it. But in some patients, particularly those with any subretinal PFO, retinal atrophy and chronic choroiditis can be seen. This will require surgical removal, especially if the PFO is trapped near...

If the orbital cellulitis is infectious, I never add steroids. There is no literature or proof that they do anything, and decreasing immunity, in my opinion, is simply a bad idea. If it is inflammatory, then absolutely. Most infectious orbital cellulitis is from the sinuses and is more common in chi...

Patient-reported outcome measures after floaterectomy are also subjective. The improvement in symptoms following vitrectomy (I do...

Since these drugs have a significant risk and a marginal benefit, not to mention the significant treatment burden and their outrageous cost, it begs the question of how often they should be used altogether.
