RESUMO
Purpose: The aim of this research is to describe the use of the social media platform, Instagram, by academic ophthalmology residency programs in the United States over time and consider the impact of the COVID-19 pandemic on ophthalmology's social media presence. Methods and Subjects: This cross-sectional study was conducted online by reviewing the publicly accessible Instagram accounts of all accredited US academic ophthalmology residency programs. Main Outcomes and Measures: Number of US ophthalmology residency programs with an affiliated Instagram account were analyzed by year of creation. The content of the top six accounts with the most followers was analyzed by evaluating amount of engagement within defined post categories. Results: Of the 124 ophthalmology residency programs, 78 (62.9%) were identified as having an affiliated Instagram account, 60 accounts (48.4%) were created during the years 2020 or 2021, and 62 (50.0%) accounts focused specifically on promoting the residency training program. Of the top six accounts with the most followers, post categories that received the most engagement were "Medical" and "Group Photo", while those that received the least engagement were "Department Bulletin" and "Miscellaneous." User engagement on posts as measured by likes and comments increased across multiple post categories after January 2020. Conclusion: Social media presence of ophthalmology residency programs on Instagram increased substantially in 2020 and 2021. As a result of the COVID-19 pandemic restricting in-person interactions, residency programs have used alternative platforms to reach applicants. Given the increasing use of such applications, social media will likely continue to become an important aspect of professional engagement in ophthalmology.

Purpose: We describe a patient with elevated intraocular pressure (IOP) secondary to an oral water bolus and examine the utility of the water-drinking test. Observations: A 66-year-old male with a history of hypertension presented with headache, bilateral retro-orbital ache, and blurry vision. Symptoms began shortly after his radiation treatment for prostate cancer, for which he consumed a water bolus to fill his bladder 30 minutes prior to treatment initiation. On exam, he had bilateral elevated IOP that responded to topical IOP-lowering medications. Gonioscopy demonstrated open angles and fundus exam showed non-glaucomatous optic nerves with pronounced retinal venous tortuosity. The water-drinking test showed a peak intraocular pressure of 20 mmHg in the right eye (5 mmHg increase from baseline) and 23 mmHg in the left eye (8 mmHg increase from baseline), suggesting impairment of the outflow system in the left compared to the right eye. He was started on topical IOP-lowering therapy and followed in our clinic as a glaucoma suspect. Conclusions: Consumption of a water bolus can be associated with IOP elevation and may be a risk factor in patients with otherwise normal IOPs at risk for glaucoma. The water-drinking test was historically used as provocative testing for open-angle glaucoma and may have an updated role in evaluating at-risk patients without ocular hypertension.
RESUMO
The most common cause of both unilateral and bilateral proptosis in adults is thyroid eye disease (TED), and the diagnosis in typical cases is made without imaging. However, many other orbital diseases, including inflammatory, infectious, and neoplastic processes, can mimic the symptoms of thyroid eye disease, highlighting the importance of imaging and biopsy in challenging cases. There are limited reports in the literature of orbital lymphoma being diagnosed in patients with a history of thyroid eye disease. Here, we present the case of a patient with long-standing TED who developed new asymmetric proptosis and was subsequently diagnosed with systemic follicular lymphoma.

Primary open-angle glaucoma (POAG) is the leading cause of irreversible blindness worldwide and has been associated with multiple genetic risk factors. The LMX1B gene is a genetic susceptibility factor for POAG, and several single-nucleotide polymorphisms (SNPs) were shown to be associated with POAG in our own prior Primary Open-Angle African American Glaucoma Genetics (POAAGG) study genome-wide association study (GWAS). This study evaluated the association of the LMX1B locus with baseline optic disc and clinical phenotypic characteristics of glaucoma patients from our African American cohort. Compared to the GG genotype in SNP rs187699205, the GC genotype in this SNP was found to be significantly associated with a smaller cup-to-disc ratio (CDR) and increased (better) visual field mean deviation (MD) in glaucoma cases. None of the glaucoma cases with the GC genotype had disc hemorrhages, disc notching, or beanpot disc appearance. In conclusion, glaucoma phenotypes differed significantly by LMX1B variant in African American patients with POAG, and a SNP variant was associated with certain disease features considered lower risk.

INTRODUCTION: Computer-based video training (CBVT) of surgical skills overcomes limitations of 1:1 instruction. We hypothesized that a self-directed CBVT program could teach novices by dividing basic surgical skills into sequential, easily-mastered steps. METHODS: We developed a 12 video program teaching basic knot tying and suturing skills introduced in discrete, incremental steps. Students were evaluated pre- and post-course with a self-assessment, a written exam and a skill assessment. RESULTS: Students (n = 221) who completed the course demonstrated significant improvement. Their average pre-course product quality score and assessment of technique using standard Global Rating Scale (GRS) were <0.4 for 6 measured skills (scale 0-5) and increased post-course to ≥3.25 except for the skill tying on tension whose GRS = 2.51. Average speed increased for all skills. Students' self-ratings (scale 1-5) increased from an average of 1.4 ± 0.7 pre-elective to 3.9 ± 0.9 post-elective across all skills (P < 0.01). CONCLUSION: Self-directed, incremental and sequential video training is effective teaching basic surgical skills and may be a model to teach other skills or to play a larger role in remote learning.

BACKGROUND/AIMS: Split-spectrum amplitude decorrelation angiography for spectral-domain optical coherence tomography has enabled detailed, non-invasive assessment of vascular flow. This study evaluates choriocapillaris and retinal capillary perfusion density (CPD) in diabetic eyes using optical coherence tomography angiography (OCTA). METHODS: Records of 136 eyes that underwent OCTA imaging at a single institution were reviewed. Eyes were grouped as non-diabetic controls (37 eyes), patients with diabetes mellitus (DM) without diabetic retinopathy (DM without DR, 31 eyes), non-proliferative diabetic retinopathy (NPDR, 41 eyes) and proliferative diabetic retinopathy (PDR, 27 eyes). Quantitative CPD analyses were performed on OCTA images for assessing perfusion density of the choriocapillaris and retinal plexus for all patients and compared between groups. RESULTS: Eyes with NPDR and PDR showed significantly decreased choriocapillaris CPD compared with controls, while DM eyes without DR did not show significant change. Choriocapillaris whole-image CPD was decreased by 8.3% in eyes with NPDR (p<0.01) and decreased by 7.1% in eyes with PDR (p<0.01). Choriocapillaris parafoveal CPD was decreased by 8.9% in eyes with NPDR (p<0.01) and decreased by 8.2% in eyes with PDR (p<0.01). Compared with controls, only eyes with PDR showed significantly decreased retinal CPD, as well as significantly increased foveal avascular zone (FAZ) area. In those patients, retinal whole-image CPD was decreased by 9.7% (p<0.01), retinal foveal CPD was decreased by 20.5% (p<0.01) and retinal parafoveal CPD was decreased by 11.4% (p<0.01). FAZ area was increased by 50.9% (p<0.01). CONCLUSIONS: Choriocapillaris and retinal CPD are reduced in diabetic retinopathy, while FAZ area is increased in eyes with PDR. Vascular changes captured by new imaging modalities can further characterise diabetic choroidopathy.

PURPOSE: To compare long-term surgical outcomes and complications of pars plana (PP) tube implantation with conventional anterior chamber (AC) tube implantation. MATERIALS AND METHODS: Records of patients undergoing glaucoma tube implant surgery at a single institution between 2007 and 2015 were retrospectively reviewed. Eyes were matched for glaucoma diagnosis and patient age. Demographics, baseline characteristics, and treatment outcomes were recorded. Surgical success was defined as intraocular pressure (IOP) between 6 and 21 mm Hg, no subsequent glaucoma surgeries performed, and at least light perception vision. RESULTS: Fifty-seven eyes that underwent Ahmed or Baerveldt glaucoma drainage device surgery with PP tube placement were compared with 57 eyes with AC tube placement. Mean follow-up was 43.5 months in the PP group and 35.3 months in the AC group (P=0.02). Forty-nine (86.0%) PP eyes and 46 (80.7%) AC eyes achieved surgical success (P=0.45). At last follow-up, mean IOP decreased from 29.0 to 15.1 mm Hg in the PP group (P<0.01) and from 32.7 to 15.6 mm Hg in the AC group (P<0.01). Mean number of medications decreased from 2.9 to 1.1 in the PP group (P<0.01) and from 2.8 to 1.3 in the AC group (P<0.01). Mean IOP and number of medications were similar between PP and AC groups at baseline, last follow-up, and all interim time points (P>0.05 for all). There were 16 complications in the PP group and 14 in the AC group (P=0.67). CONCLUSIONS: Long-term results of glaucoma tube implant surgery with PP versus AC implantation shows effective IOP control with similar rates of surgical success.

PURPOSE: To summarize the findings of long-term outcomes of anti-vascular endothelial growth factor (VEGF) therapy (≥36 months) in patients with exudative age-related macular degeneration. METHODS: Studies reporting long-term outcomes (≥36 months) of anti-VEGF therapy (n = 11) were identified and analyzed for changes in visual acuity (VA), optical coherence tomography, and safety findings. RESULTS: Six prospective extension studies of Phase 3 clinical trials and five retrospective evaluation studies were identified. The largest improvements in VA with anti-VEGF treatment were found in Years 1 to 2 after treatment initiation. In five studies, VA ultimately declined below patients' pretreatment initial baseline; in three studies, VA ultimately returned to patients' baseline; in three studies, VA decreased but ultimately remained improved over patients' baseline. There was a trend demonstrating that a higher frequency of intravitreous injections showed a better maintenance in VA. Rates of adverse events were similar to previous registration studies of anti-VEGF drugs. CONCLUSION: The body of evidence to date regarding long-term anti-VEGF treatment indicates a variable course at greater than 36 months follow-up and seems to be dependent on the treatment protocol. Consistent dosing with fluid-free interval is suggested to maintain VA gains in patients with exudative age-related macular degeneration. There is no evidence suggesting that there are additional adverse events from long-term anti-VEGF use.

PURPOSE OF REVIEW: The article presents a review of recently published studies reporting postcataract surgery outcomes and the use of electronic systems to track them. RECENT FINDINGS: Current publications report several parameters to measure cataract outcomes such as visual acuity, patient-reported visual function, contrast sensitivity, reading speed, residual refractive errors and complications (intraoperative and postoperative). SUMMARY: Cataracts currently afflict an estimated 94 million people worldwide, and surgical removal is the only effective therapy known. Tracking outcomes through registry databases has been shown to be a powerful tool for improving patient outcomes, understanding and adopting best clinical practices, reducing costs and increasing value delivered. Large datasets present in electronic registry systems are valuable resources for evaluating the quality of care by allowing researchers and healthcare providers to analyze, understand and adjust to 'real-world' best practices and adverse events.
