RESUMEN
Purpose: Compare estimated sensitivities of SITA-Standard to the RATA-Standard algorithm of the Radius virtual reality perimeter (VRP), and measure concordance in glaucoma staging. Methods: One hundred adult glaucoma patients-half with suspect or mild glaucoma, and half with moderate or severe-from five clinics performed four 24-2 visual field tests during a single visit, two with the Humphrey Field Analyzer (HFA) and two with Radius, in randomized order: HRHR or RHRH. Only one eye was tested per participant. We used the Wilcoxon rank sum test with Bonferroni correction to compare distributions of estimated sensitivities across all 54 test locations over the 15 to 40 dB measurement range of the Radius. Weighted kappa measured concordance in glaucoma staging between two masked glaucoma experts using Medicare definitions of severity. Results: A total of 62 OD and 38 OS eyes were tested. Estimated sensitivities for SITA-Standard and RATA-Standard were not significantly different for OD, but were for OS-likely because of SITA-Standard OD and OS being significantly different in our sample, but not for RATA-Standard. Low agreement was observed between 15 to 22 dB. Concordance in glaucoma staging was high for both graders: kappa = 0.91 and kappa = 0.93. Average test duration was 298 seconds for RATA-Standard and 341 seconds for SITA-Standard. The correlation in mean deviation was 0.94. Conclusions: Estimated sensitivities of RATA-Standard are comparable to SITA-Standard between 23 to 40 dB with high concordance in glaucoma staging. Translational Relevance: Radius VRP is statistically noninferior to HFA when staging glaucoma using Medicare definitions.

Ocular surface disease (OSD) is a complex condition that can cause a range of symptoms (e.g, dryness, irritation, and pain) and can significantly impact the quality of life of affected individuals. Iatrogenic OSD, a common finding in patients with glaucoma who receive chronic therapy with topical ocular antihypertensive drugs containing preservatives such as benzalkonium chloride (BAK), has been linked to damage to the ocular surface barrier, corneal epithelial cells, nerves, conjunctival goblet cells, and trabecular meshwork. Chronic BAK exposure activates inflammatory pathways and worsens symptoms, compromising the success of subsequent filtration surgery in an exposure-dependent manner. In eyes being treated for glaucoma, symptomatic treatment of OSD may provide some relief, but addressing the root cause of the OSD often necessitates reducing or, ideally, eliminating BAK toxicity. Strategies to decrease BAK exposure in patients with glaucoma encompass the use of preservative-free formulations or drugs with alternative and less toxic preservatives such as SofZia®, Polyquad, potassium sorbate, or Purite®. Though the benefits of these alternative preservatives are largely unproven, they might be considered when financial constraints prevent the use of preservative-free versions. For patients receiving multiple topical preserved drugs, the best practice is to switch to nonpreserved equivalents wherever feasible, regardless of OSD severity. Furthermore, nonpharmacological approaches, including laser or incisional procedures, should be considered. This review explores the effects of BAK on the ocular surface and reviews strategies for minimizing or eliminating BAK exposure in patients with glaucoma in order to significantly improve their quality of life and prevent complications associated with chronic exposure to BAK.
RESUMEN
PRCIS: About 1/4th of survey respondents from an ASCRS database initiate treatment for primary open-angle glaucoma (POAG) with laser trabeculoplasty. Factors impacting physicians' choice of laser versus topical treatment for POAG were explored. PURPOSE: To characterize primary treatment preferences (topical medication vs. laser trabeculoplasty or intracameral sustained release implants) in primary open-angle glaucoma (POAG) patients and determine factors related to primary intervention selection. METHODS: A 33-question survey was distributed to an American Society of Cataract and Refractive Surgery database on treatment choices made by ophthalmologists for POAG. Data collected included country of practice, years of practice, completion of glaucoma fellowship training, type of practice, and preference for first line of treatment of POAG. Multiple logit regression was used to compare the effect of covariates on physicians' choice of either topical medication or laser trabeculoplasty for POAG. RESULTS: A total of 252/19,246 (1.3%) of surveys were returned. Almost three-quarters of respondents utilized topical medication as first line of treatment for POAG (73.6%) while 26.4% preferred to start with laser treatment. Significant variables associated with the selection of laser (vs. drops) are practicing in the U.S. (odds ratio [OR] 2.85, 95% confidence interval [CI] 1.33-6.10), more recent completion of ophthalmology residency (OR 1.95, 95% CI 1.00-3.77), greater volume of minimally invasive glaucoma surgeries (MIGS) (OR 1.68, 95% CI 1.18-2.40), and a glaucoma patient base greater than 25% (OR 2.21, 95% CI 1.09-4.48). CONCLUSIONS: For the first line treatment of POAG, laser trabeculoplasty is more likely to be preferred, over topical drops, by U.S. physicians who are relatively new in practice, who have a larger glaucoma patient base and who perform more MIGS.
RESUMEN
BACKGROUND AND OBJECTIVE: To assess ocular, visual, and anatomical outcomes following the 0.19-mg fluocinolone acetonide (FAc) intravitreal implant (ILUVIEN®) and incisional intraocular pressure (IOP)-lowering surgery in diabetic macular edema. PATIENTS AND METHODS: From a 36-month, phase 4, open-label, observational study (N = 202 eyes, 159 patients), 8 eyes (7 patients) required IOP-lowering surgery post-FAc; eyes were segregated by FAc-induced (n = 5, 2.47%) versus neovascular glaucoma (NVG)-related (n = 3, 1.49%) IOP elevations and assessed for IOP, best corrected visual acuity (BCVA), central subfield thickness (CST), and cup-to-disc ratio (c/d). RESULTS: Changes at 36 months were +5.4 letters BCVA (P > 0.05) and +0.09 c/d (P = 0.0217); IOP and CST were unchanged. FAc-induced-group eyes required fewer IOP-lowering medications than NVG-group eyes (2.0 versus 4.0; P < 0.01) but for longer duration (15.2 versus 2.6 months; P < 0.001). CONCLUSIONS: Post-FAc IOP-lowering surgery, regardless of cause, largely did not affect the outcomes measured; these procedures, then, may not meaningfully threaten positive outcomes.
