How do you optimize retinopathy screening schedules for patients on hydroxychloroquine while also prioritizing cost-effectiveness?
I'll approach this from the cost-effectiveness standpoint as I agree with Drs. @Dr. First Last and @Dr. First Last on their excellent points.Patients with SLE have remarkably high costs when you add up copays, medications, imaging studies, travel, missing work, etc. Anything we can do to help reduce...
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...
For patients with evidence of prior bilateral uveitis (PS, pupillary membranes, inactive KP, no view posteriorly) who reports no prior symptoms and who has had negative lab work-up, when do you consider repeat work-up and which labs would you repeat?
This is a difficult question to answer succinctly, as so much information is missing to provide a complete response. However, it does raise some important points that are worth mentioning:There is a prevailing tenet, which I was taught as a resident and hear often from residents today, that 1st epis...
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 agehttps://eyewiki.org/File:Randleman.jpg
What are some methods to deal with IOP elevations with intravitreal injections in a patient without glaucomatous damage that does not want to have AC taps with each injection?
In this situation, depending on the elevated IOP, use the standard medical approach: Iopidine1%, Cosopt, Alphagan 0.2%, and in some cases, Diamox 250 mg. Wait for half an hour and repeat if necessary, or send the patient home with one or more drugs. Of course, make sure of drug selective contraindic...
Do you modify your cataract surgery (i.e., biometry, phaco parameters, post-operative regimen) in any way for patients with prior glaucoma surgeries and/or severe glaucoma?
I generally do not modify my cataract surgery settings or pre-op planning. For patients with filtering blebs, I review the risks that cataract surgery could cause increased IOP and in some cases, bleb failure. For patients with filtering blebs who might be on one or more drops, I might consider bleb...
How do you approach the treatment of "normal tension glaucoma" and how do you discuss this with patients?
It highlights that glaucoma is probably not an eye pressure disease, but rather a vascular disease. As noted above, there is a genetic component clearly, but vasculopaths (DM, Sleep apnea, CVD, etc.) increase that risk with the same IOP.
In primary angle closure suspects without cataracts, how do you approach the discussion about LPIs, given the relatively low risk of an acute angle closure attack?
In primary angle closure suspects without cataracts, I will have a discussion about aqueous humor dynamics and outflow mechanisms of the eye, and how that relates to risk stratification in the patient's case. We are fortunate in glaucoma to have a fair bit of evidence to guide us in our clinical dec...
What type of air/SF6 fill do you recommend following DSEAK in patients with scleral fixated IOLs? (i.e., only AC fill vs full eye fluid-gas exchange?)
For these patients, I do a suture pull-through technique with a Prolene suture to anchor the graft at the distal edge. To keep chamber stability and prevent the bubble from moving posteriorly, I suture all wounds, including the paracenteses. I use 18% SF6 or 6% C3F8 and do a full fill. C3F8 has beco...
When should you seek hyperbaric oxygen therapy for patients with CRAO?
I usually pursue hyperbaric oxygen therapy within the 24-hour window from symptom onset for CRAO. This can be performed following TNK if given. In reality, though, there are multiple barriers to achieving this, including: Few centers offer hyperbaric oxygen therapy Labor intensive Difficulty with i...
