How do you approach management of GLP-1 receptor agonist therapy in patients who develop NAION?
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. While some studies indicate links between GLP-1 agonists and NAION, there are so many discussions arou...
How do you approach cases of transient monocular vision loss when initial carotid imaging and cardiac workup are unrevealing?
As you eluded, it is essential to rule out amaurosis fugax in a case of TMVL, and carotid Doppler and cardiac echo are two essential tests to evaluate the two potential sources of embolization in this setting. I would also recommend an MRI of the brain (to check for possible evidence of other ischem...
How do you counsel patients with GCA on the benefits of steroids who have already experienced vision loss?
I first tell the patient they are at considerable risk for further visual loss in the same eye or the other eye over the next 1-2 weeks. I also let them know that, even though their risk of visual loss has been reduced, their best option for preventing further visual loss is immediately starting hig...
What specific exam findings or test changes prompt escalation of care when evaluating pediatric patients with optic disc drusen for possible increased intracranial pressure?
Both pediatric and adult patients with optic disc drusen can develop increased intracranial pressure, including IIH, like normal individuals. This is important to remember, especially if the symptoms and risk factors suggest elevated intracranial hypertension. In the pediatric group, especially youn...
What are the toxic effects of a small amount of intraocular perfluoron on the retina and cornea?
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...
When do you consider adding steroids alongside intravenous antibiotics for patients with orbital cellulitis?
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...
How should ectasia risk be triaged using RSB, PTA, and tomography?
Randleman ectasia risk score is very helpful in assessing the risks. It takes into consideration RSB PTA topography, CT, and age. Randleman Ectasia Risk Factor Score System
What clinical and diagnostic factors best predict who will benefit from intervention versus observation for patients with visually significant floaters?
There are no clinical or diagnostic factors that predict who will benefit from an intervention for vitreous floaters. Symptomatology from vitreous floaters is subjective. Patient-reported outcome measures after floaterectomy are also subjective. The improvement in symptoms following vitrectomy (I do...
How do you determine when to discontinue anti-complement therapy in patients with geographic atrophy who already have center-involving disease given the minimal likelihood of central vision improvement but the potential for more rapid scotoma expansion if treatment is withdrawn?
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.
How do you approach diagnosis and management of orbital myositis?
Orbital myositis is an umbrella diagnosis that includes a wide range of potential underlying conditions. Patients with this presentation are often first evaluated by neuro-ophthalmology to exclude causes such as isolated orbital myositis, myasthenia gravis, thyroid eye disease, infection, and diabet...
