Do you feel there are medical advantages to FLACS and if so, what are they and how often are you offering FLACS to patients?
That's a question that's sure to trigger contentious responses!Personally, I think the capability of making toric marks on the cornea or lens capsule to line up toric lenses (and using iris registration to do so), as well as the ability to do LRIs, does offer some advantage for accuracy in astigmati...
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...
In quiescent patients with history of herpetic keratouveitis with uncontrolled IOP on topicals, do you prescribe PGAs?
The evidence on prostaglandin analogues (PGAs) in the setting of herpetic anterior uveitis is nuanced. Traditionally, we have been taught to avoid PGAs in the setting of herpetic disease, given the theoretical concerns that these drugs could compromise the host's interferon defense system. But, more...
What is the best next surgical approach to manage severe inferior oblique overaction and superior oblique underaction after inferior oblique myectomy?
Persistent superior oblique (SO) muscle underaction after inferior oblique (IO) myectomy usually indicates an abnormal, loose, and floppy superior oblique tendon. At surgery, the first thing to do is traction testing of both oblique muscles to detect tightness or laxity. Videos of the "exaggerated t...
How do you monitor and manage visual development and amblyopia in children with glaucoma who require multiple surgeries during critical periods of visual maturation?
There is nothing special about managing visual development and amblyopia in children with glaucoma. They must be followed by a pediatric ophthalmologist and a cycloplegic refraction performed at least yearly (more frequent if a change is expected based on changes in vision or axial length) and glass...
What is the role of topical aqueous suppressants as an adjunct to intravitreal anti-VEGF therapy in patients with persistent macular edema despite optimized injection frequency depending on etiology of ME?
Interesting question: It isn't stated what the cause of the macular edema is. In the only two indications for which there is evidence that anti-VEGF injections can have value (RVO and DME), there is little evidence of aqueous suppressants being of any value. So, in my opinion, non-intersecting sets....
What has been your experience with dSLT?
Overall positive. The procedure is quick and the interface is intuitive. We have to warn the patients that they are going to feel it, and oh man, if you look at the anterior chamber about 20 minutes after the dSLT, you are going to see a lot of cells floating around there. I have been able to perfor...
What techniques do you use to minimize the risk of buckle extrusion or infection, especially in younger or highly myopic patients?
No different techniques. Make sure you soak the elements in saline with an antibiotic. Do not touch the buckle with your hands. Do not use instruments that can damage the silicone. Extrusions and infections are not common. Kids have a healthy Tenon that will keep buckles from extruding. Also, buckle...
How do you determine the duration and taper of systemic corticosteroids when you add them alongside antibiotics for orbital cellulitis?
There is no 'standard of care' answer for this. My personal preference is the following: Pediatric patients -- 0.25 to 0.5 mg/kg dexamethasone daily (given in AM) for up to 3 days, starting the day after source control/cultures from surgery. Higher dose/longer duration if very inflamed, and lower d...
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 ...
