In what cases do you consider mannitol for cataract surgery?
I have found IV mannitol VERY helpful for dehydrating vitreous for short axial length, especially around 20.5 or less. Otherwise, in short eyes, there is less working space and a greater tendency for the iris to want to prolapse out, even in the absence of typical IFIS-type medications. I’ve typical...
In extensive basal cell carcinoma involving both upper and lower eyelids and the lacrimal gland, is radiotherapy poorly tolerated (especially to doses up to 50-60 Gy) and/or is orbital exenteration preferred?
For advanced basal cell carcinoma with orbital invasion, I would treat with hedgehog inhibitors. If there is an inadequate clinical response, exenteration is usually recommended. Radiation is not particularly effective for BCC and can have significant ocular side effects.
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 incorporate OCT and OCT-A in conjunction with FA in your evaluation of retinal diseases?
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 manage the severe adverse drug reaction of central serous retinopathy with MEK inhibitors?
Fortunately, the ICSC-like association of subretinal fluid with MEK inhibitor exposure is usually reversible after cessation of the drug. When working with this class of medications, it is important to coordinate care with the treating oncologist. If a patient presents with subretinal fluid and is o...
What is your algorithm for transitioning a patient with chronic noninfectious posterior uveitis from corticosteroids to immunosuppressive therapy?
There are some forms of noninfectious posterior/panuveitis where it is known from the time of uveitis diagnosis that steroid-sparing immunosuppression (IMT) will be needed. For example, in birdshot retinochoroiditis or serpiginous choroidopathy, IMT is often initiated in concert with oral corticoste...
How do you decide the threshold and duration of subretinal fluid that can be safely tolerated in exudative AMD when adjusting treat-and-extend intervals?
There are so many other factors at play here. The very nature of this question begs the question of whether you are treating the patient or the OCT. Sadly, it appears the preponderance of patients I have seen are treated at fixed intervals of 1-2 months and no treat and extend, even from physicians ...
How do you approach offering multifocal IOLs to patients with prior retinal pathology and surgery (i.e., mac-off RD) who have had relatively good recovery of vision?
As a retina specialist, I have seen a significant increase, over recent years, in patients doing badly because someone inserted a multifocal IOL in the context of prior or impending retinal disease. In most of these cases, the patients seemed naive to the implications, reporting that they were told ...
In patients with treated endophthalmitis secondary to a bleb leak, how do you determine timing of revision?
There are really two separate (but related) issues to address here: The infection. This is treated in conjunction with my vitreoretinal colleagues, as it will require intravitreal antibiotics +/- vitrectomy, depending on the degree of posterior segment involvement. Of course, the bleb is also cultu...
Is optimal timing of choroidal drainage in the case of kissing choroidals with hypotony after glaucoma surgery different in a vitrectomized eye?
To answer the question, probably the timing is not different for a vitrectomized eye. One could make the case for more immediate surgery in the sense that there is no vitreous buffer between appositional retina layers, but I doubt there's much data to support that. On the subject of timing in genera...
