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...
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...
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...
In patients with progressive AZOOR who demonstrate enlarging zones of outer retinal loss despite corticosteroid therapy, how do you determine when to escalate to steroid-sparing immunomodulatory agents?
We should first be sure this is not a "masquerade" syndrome such as vitreoretinal lymphoma, infectious uveitis, or IRD. If these are considered unlikely, then at this point in the course, where there is documented progression of a presumed inflammatory process, systemic IMT should be considered. Som...
How do you decide between a combined phacovitrectomy approach versus a staged procedure for patients with a retinal detachment and dense cataract?
A primary buckle might be a consideration here to avoid the issue of the cataract altogether. But if planning to add a buckle (with vitrectomy) during these cases, it is impossible to preoperatively perform lens measurements (i.e., axial length), which would be a relative contraindication to perform...
How would you manage a patient who develops a 1 mm abscess at the internal os of the paracentesis tract following an AC tap after an Izervay injection with eye pain but no vitreous cell or retinal involvement?
It sounds like a very specific question! Never having seen a paracentesis ulcer after 30 years of surgeries with paracenteses from iris hooks, and >10s of thousands of injections (albeit mostly without paracenteses), I'd have to say this is rarer than endophthalmitis. Treat it like a corneal ulcer. ...
Who is your ideal candidate for a XEN over other filtering procedures such as trabs or tubes?
I typically reserve the Xen Gel Stent for elderly, Caucasian patients, especially women, with moderate open-angle glaucoma who need better pressure control but don’t require single-digit IOPs. These patients tend to have thinner, less fibrotic Tenon’s capsules and a lower risk of scarring, which all...
What is your preferred surgical approach for revision of an over-filtering bleb?
Hypotony after trabeculectomy is not uncommon, and I generally inform my patients prior to surgery that the risk of hypotony is roughly 10-20%. But, as is well known, not all patients develop hypotony maculopathy or detrimental effects from low IOP, and some patients can do well with IOP in the hypo...
For patients with neovascular glaucoma and uncontrolled IOP, do you ever consider a glaucoma drainage device (GDD) combined with ECP as opposed to just a standalone GDD?
I've never performed those two surgeries together, and I don't know of any papers that looked at that. Many NVG patients who get tubes in my practice are phakic, which makes ECP a non-starter. For the pseudophakic ones, I usually do a tube alone, combined with anti-VEGF and PRP. I would consider ECP...
How long should you wait after superficial keratectomy for accurate IOL measurements?
I wait at a minimum of 4 weeks and reassess the topography to see if it stabilizes. If not stable, I will repeat every 4 weeks until stable (usually no more than 3 months needed).
