Are there any special considerations for cataract surgery in a patient with ICE syndrome (Chandler) with a relatively clear cornea?
It is important to try and get a cell count before surgery to manage patient expectations in case of increased risk of endothelial failure. The cataract surgery should be straightforward unless there is a correctopia needing a pupillary dilator. To note that MIGS are usually not successful when comb...
Have you found a successful treatment option for fixed Descemet's folds following prolonged hypotony (after hypotony has been treated/resolved) or Descemet's striae from a surgical incision?
These are difficult situations. The best success I have had is doing DSEKs and suturing the graft in 4 quadrants with 10-0 nylon to prevent detachment. It takes longer to clear but prevents detachment, and the sutures can be removed once the edema is clear. The lifespan of these transplants is inher...
How do you approach surgical repair of a 6-clock-hour retinal dialysis with posteriorly folded retina, and what strategies do you use to minimize retinal slippage?
First of all, make sure it’s a dialysis and not a GRT. For dialysis, I would definitely start with a buckle.
Do you incorporate diurnal or nocturnal IOP measurements in your management of progression despite seemingly adequate daytime control?
The advent of home-based tonometry can make diurnal or nocturnal IOP measurements more convenient to obtain, though the cost of renting or buying these devices may be prohibitive for some patients. Glaucoma specialists sometimes use diurnal or nocturnal IOP measurements to identify whether there are...
In patients with end-stage glaucoma requiring surgery (cataract or incisional glaucoma surgery), how do you approach discussion of possible "snuff" and how does this factor in your decision to proceed with surgery?
I have operated on hundreds, if not thousands, of patients with end-stage glaucoma over my career. Many CAT IOL + bleb surgery or Cat IOL alone. I cannot remember a snuff directly related to surgery. Judicious use of ER acetazolamide immediately postoperatively goes a long way. If cat IOL alone and ...
What is your approach to antiviral treatment of HSV acute retinal necrosis?
Acute Retinal Necrosis (ARN) is a rapidly progressive syndrome usually caused by varicella-zoster virus (VZV)and herpes simplex virus 1 or 2 (HSV). The syndrome is rapidly progressive in the absence of antiviral treatment. PCR performed on aqueous or vitreous sampling is highly sensitive and strongl...
Do you routinely recommend IV systemic antibiotic therapy in additional to intravitreal antibiotic therapy for exogenous bacterial endophthalmitis?
Post-surgical (exogenous) endophthalmitis is an uncommon complication with the incidence ranging from 0.04%-0.3%, 0.019%- 0.54%, and 0.11% - 0.03% following cataract surgery, intravitreal injection, and vitrectomy, respectively (Soliman et al., PMID 32467482). Initial management of exogenous endopht...
In pediatric RRDs associated with high myopia or Stickler syndrome, how do you decide between scleral buckle alone versus combined vitrectomy and buckle?
Most of the time, a buckle works great. If there is posterior PVR that will not relax with a buckle or there is a GRT, then a vitrectomy will be necessary.
In patients with glaucoma who are not ideal candidates for goniotomy, angle stenting, tubes, or trabeculectomy, does the use of AlloFlo provide safe and predictable IOP control compared to other surgical options?
I have used it on one patient with severe glaucoma and a poor filtration bleb candidate. Bilateral implants. Pre-surgery IOP mid 20’s 4 meds. Now on latanoprost OU, IOP 15 OU. Now PO 3-4 months. Alloflo literature I believe shows a 40% reduction in IOP with a 40% reduction in medications at the 2-3 ...
What is your approach to intralesional steroid injection for chalazia (in terms of dosage, approach, timing)?
I offer the option of intralesional steroid to all patients with chalazia, particularly if there is significant inflammation present. I give up to 1 cc of a 10 mg/mL solution of dexamethasone. I have approached this by both transconjunctival as well as transcutaneous. I think transconjunctival hurts...
