Risk of Endophthalmitis Based on Cumulative Number of Anti-VEGF Intravitreal Injections.

PURPOSE: To determine the risk of endophthalmitis in eyes undergoing intravitreal injections (IVIs) of anti-VEGF based on cumulative number of injections per eye. DESIGN: Retrospective cohort study. PARTICIPANTS: Patients from a single center undergoing IVIs of ranibizumab, aflibercept, or bevacizumab. METHODS: Eyes were divided into quartiles based on injection number causative of endophthalmitis between January 1, 2011, and June 1, 2022. MAIN OUTCOME MEASURES: Interquartile clinical outcomes and cumulative risk of endophthalmitis per injection and per eye. RESULTS: A total of 43 393 eyes received 652 421 anti-VEGF injections resulting in 231 endophthalmitis cases (0.035% per injection, 1 in 2857), of which 215 were included. The cumulative endophthalmitis risk increased from 0.0018% (1 in 55 556) after 1 injection to 0.013% (1 in 7692) after 11 injections (0.0012 percentage point change), versus 0.014% (1 in 7143) after 12 injections to 0.025% (1 in 4000) after 35 injections (0.00049 percentage point change), versus 0.025% (1 in 4000) after 36 injections to 0.031% (1 in 3226) after 66 injections (0.00017 percentage point change), versus 0.031% (1 in 3226) after 63 injections to 0.033% (1 in 3030) after 126 injections (0.000042 percentage point change) (P < 0.001). Likewise, the cumulative endophthalmitis risk per eye increased from 0.028% (1 in 3571) to 0.20% (1 in 500) between injections 1 and 11 (0.018 percentage point change), versus 0.21% (1 in 476) to 0.38% (1 in 263) between injections 12 and 35 (0.0075 percentage point change), versus 0.38% (1 in 263) to 0.46% (1 in 217) between injections 36 and 66 (0.0026 percentage point change), versus 0.46% (1 in 217) to 0.50% (1 in 200) between injections 67 and 126 (0.00063 percentage point change) (P < 0.001). CONCLUSIONS: The cumulative endophthalmitis risk per injection and per eye increased with greater number of injections received but appeared to do so at a higher rate during earlier injections and at a lower rate further into the treatment course.

Timely Completion of Direct Access Colonoscopy Is Noninferior to Office Scheduled for Screening and Surveillance.

GOALS: We aimed to evaluate whether direct access colonoscopy (DAC) is noninferior to office-scheduled colonoscopy (OSC) for achieving successful colonoscopy. BACKGROUND: DAC may improve access to colonoscopy. We developed an algorithm assessing eligibility, risk for inadequate preparation, and need for nursing/navigator assistance. STUDY: This was a retrospective, single-center study of DAC and OSC patients from June 5, 2018, to July 31, 2019. Patients were 45 to 75 years old with an indication of screening or surveillance. A successful colonoscopy met 3 criteria: complete colonoscopy (cecum, anastomosis, or ileum), adequate preparation (Boston Score ≥2/segment), and performed <90 days from initial patient contact. Unsuccessful colonoscopy did not meet ≥1 criteria. Secondary end points included days to successful colonoscopy, preparation quality, polyp detection, and 10-year recall rate. Noninferiority against risk ratio value of 0.85 was tested using 1-sided alpha of 0.05. RESULTS: A total of 1823 DAC and 828 OSC patients were eligible. DAC patients were younger, with a greater proportion of black patients and screening indications. For the outcome of successful colonoscopy, DAC was noninferior to OSC (DAC vs. OSC: 62.7% vs. 57.1%, RR 1.16, 95% LCL 1.09, P=0.001). For DAC, days to colonoscopy were fewer, and likelihood of 10-year recall after negative screening greater. Boston Score and polyp detection were similar for groups. Black patients were less likely to achieve successful colonoscopy; otherwise, groups were similar. For unsuccessful colonoscopies, proportionally more DAC patients canceled or no-showed while more OSC patients scheduled >90 days. DAC remained noninferior to OSC at 180 days. CONCLUSIONS: DAC was noninferior to OSC for achieving successful colonoscopy, comparing similarly in quality and efficiency outcomes.

SECONDARY EPIRETINAL MEMBRANE AFTER LASER RETINOPEXY FOR RETINAL TEAR OR LOCALIZED RETINAL DETACHMENT: Surgical Outcomes and Optical Coherence Tomography Structural Analysis.

PURPOSE: To assess visual acuity and optical coherence tomography outcomes after repair of secondary epiretinal membrane (ERM) after prior laser retinopexy for retinal tear with or without localized retinal detachment. METHODS: Retrospective, consecutive series. A previously described optical coherence tomography grading scheme was used for imaging analysis. RESULTS: Forty-two eyes of 42 patients were included, of which 16 (38.1%) had a concurrent localized retinal detachment. Mean logMAR visual acuity prelaser retinopexy was 0.15 ± 0.13 (Snellen 20/28), which worsened to 0.56 ± 0.42 (Snellen 20/72) before ERM surgery (P < 0.001). The mean visual acuity improved to 0.36 ± 0.30 (Snellen 20/45, P < 0.001) 3 months postsurgery and to 0.31 ± 0.32 (Snellen = 20/40, P < 0.001) at the final follow-up. Most eyes exhibited advanced ERM characteristics (n = 19 [45.2%] Stage 3 and n = 15 [35.7%] Stage 4 characteristics). The presence of inner microcystic changes (P = 0.008) and ellipsoid zone disruption (P = 0.009) at postoperative Month 3 were associated with worse final visual acuity. Eyes undergoing ERM surgery ≤180 days from laser retinopexy (n = 16, 38.1%) were younger (P = 0.024) and more likely to have Stage 4 ERM characteristics (P = 0.001). CONCLUSION: Secondary ERM after laser retinopexy may occur rapidly (<180 days) and exhibit significant anatomic alterations. The presence of inner microcystic changes and ellipsoid zone disruption postoperatively were optical coherence tomography features associated with worse final visual acuity.

Lasers for the prevention and treatment of hypertrophic scars: a review of the literature.

Despite the increasing knowledge about wound healing mechanisms and the advancements made in laser technology, hypertrophic scars remain difficult to manage. This review intends to discuss the laser devices studied in the prevention and treatment of HS, arising from trauma, surgery, and burns, detail their mechanisms of action, and emphasize those devices with the most promising effects. Most of the suggested mechanisms and explanations for the use of lasers in treating hypertrophic scars are based on selective photothermolysis, in which the light energy emitted from a laser is absorbed by its intended target, thereby disrupting existing collagen and altering the cycle of neocollagenesis. Through our literature review, we have determined that combination therapies, utilizing more than one laser target demonstrate enhanced clinical efficacy. Further, early use of laser devices has been shown to enhance the cosmetic result of sutured wounds and may play a role in preventing the development of hypertrophic scars.

Cell Culture Model to Study Cerebral Aneurysm Biology.

Mechanisms governing cerebral aneurysm (CA) formation, progression, and rupture remain incompletely understood. However, understanding such mechanisms is critical to improving treatment for patients harboring CA. In vitro studies facilitate dissecting molecular mechanisms underlying vascular pathology and allow screening of therapies that can be subsequently explored in vivo. Cerebral vascular smooth muscle cells (VSMC) are an important constituent of the vessel wall, and phenotypic modulation of these cells to a pro-inflammatory, pro-matrix remodeling phenotype appears to be important in CA pathology. We have taken a reductionist approach using cultured cerebral VSMC to further explore CA biology. We describe techniques for culturing cerebral VSMC and outline experimental approaches incorporating these cells to study CA biology.

Management of acute radiation dermatitis: A review of the literature and proposal for treatment algorithm.

Radiation dermatitis is a common sequela of radiation therapy; up to 95% of patients will develop moderate-to-severe skin reactions. No criterion standard currently exists for the treatment of acute radiation-induced skin toxicity. It is therefore imperative to develop a greater understanding of management options available to allow clinicians to make informed decisions when managing radiation oncology patients. This literature review discusses the topical agents that have been studied for the treatment of acute radiation dermatitis, reviews their mechanisms of action, and presents a treatment algorithm for clinicians managing patients experiencing radiation dermatitis.

Canaloplasty and Trabeculotomy Combined With Phacoemulsification for Primary Angle-Closure Glaucoma: A Single-Surgeon Case Series.

PURPOSE: To evaluate the outcomes of combined canaloplasty and trabeculotomy with phacoemulsification for primary angle-closure glaucoma (PACG). METHODS: In this retrospective, consecutive, single-surgeon case series, we analyzed the pre- and postoperative measurements of PACG patients who had the procedure. Adverse events were recorded. The main outcomes were mean intraocular pressure (IOP) in each quartile of the follow-up year and the number of IOP-lowering medications the patients were on by the end of each quartile compared to their baseline values. RESULTS:  A total of 46 eyes from 39 PACG patients were included. The preoperative IOP and glaucoma medications taken were 19.33±6.03 mm Hg and 1.80±1.39, respectively (N=46). Postoperative IOP means (mm Hg) in the subsequent four quartiles were 14.00±3.33 (N=44), 13.44±2.83 (N=32), 14.38±2.39 (N=16), and 14.92±2.90 (N=13) (p<0.0001). The mean number of meds was 0.32±0.80, 0.22±0.42, 0.59±0.80, and 0.08±0.28 in each respective quartile (p<0.0001), while the median was 0 across all quartiles. CONCLUSIONS: Combining the OMNI surgical system with phacoemulsification led to substantial reductions in mean IOP and the number of IOP-lowering medications when compared to baseline measurements.

Outcomes following repair of early-onset versus delayed-onset rhegmatogenous retinal detachments after acute posterior vitreous detachment.

AIM: To report anatomical and functional outcomes after surgical repair of acute-onset vs delayed-onset rhegmatogenous retinal detachments (RDs) following acute posterior vitreous detachment (PVD). METHODS: A retrospective, comparative interventional cohort study where patients presenting to a single-centre retina practice between October 2015 and March 2020 with delayed RDs (diagnosed ≥42 days after initial presentation of acute PVD) were compared with a 2:1 age-matched and gender-matched acute RD cohort (PVD and RD at initial presentation). The primary outcome was the final attachment rate and single surgery anatomic success (SSAS) at 3 months after RD repair. RESULTS: A total of 210 eyes were analysed-70 in the delayed RD group and 140 in the acute RD group. SSAS was 58/70 (82.9%) for the delayed RD group and 112/140 (80%) for the acute RD group (p=0.71). At the time of RD diagnosis, mean (SD) logarithm of minimum angle of resolution visual acuity (VA) was 0.51 (0.70) (Snellen, 20/65) in the delayed RD group vs 1.04 (0.92) (Snellen, 20/219) in the acute RD group (p<0.001). Mean VA was better at 1 and 3 months post-repair in the delayed RD group (p=0.005 and 0.041, respectively) but similar by 6 months, 12 months and at the final visit post-repair (p=0.48, 0.27, and 0.23, respectively). CONCLUSIONS: Delayed-onset RDs occurring ≥6 weeks after initial presentation to a retina specialist with an acute PVD generally had better VA at the time of RD diagnosis and faster post-surgical visual recovery compared with acute-onset RDs diagnosed at the initial presentation. No significant difference in anatomic outcomes was seen between the two groups.

Outcomes of Eyes Lost to Follow-up After Treatment With Intraocular or Periocular Steroid Injections.

Purpose: To evaluate the visual, intraocular pressure (IOP), and anatomic outcomes of eyes with loss to follow-up (LTFU) after intravitreal or periocular steroid injections. Methods: Patients receiving intraocular or periocular steroid injections and with LTFU for at least 180 days were included in this retrospective cohort study. Charts were reviewed for the visual acuity (VA), IOP, and central foveal thickness at the visit before LTFU, the first return visit, and 3, 6, and 12 months after return. Results: Fifty-three eyes of 47 patients were identified. The mean (±SD) age was 62.3 ± 14.9 years, the mean LTFU time was 295 ± 181.2 days (range, 182-1101), and the mean follow-up after return was 354 ± 339.3 days (range, 32-1141). The overall mean number of steroid injections was 5.2 ± 3.9 (range, 1-18). Compared with the mean logMAR VA at the visit before LTFU (0.59 [Snellen 20/77]), the mean VA remained stable at all timepoints after return as follows: return visit (0.62 [20/83]; P = .6), month 3 (0.55 [20/70]; P = .6), month 6 (0.55 [20/70]; P = .5), month 12 (0.64 [20/87]; P = .6), and final visit (0.69 [20/97]; P = .2). At the first return visit, 8 (15%) of 53 patients had an IOP of 21 mm Hg or higher (range, 21-31); 2 required treatment with a new antihypertensive medication (latanoprost and timolol, respectively). Conclusions: Patients with LTFU after receiving steroid injections maintained their VA. No patient required incisional glaucoma surgery. Compared with other etiologies, eyes with diabetic macular edema had a greater increase in IOP.

Neurotrophic keratopathy following rhegmatogenous retinal detachment surgery.

OBJECTIVE: To describe clinical characteristics and visual outcomes of eyes developing neurotrophic keratopathy (NK) following rhegmatogenous retinal detachment (RRD) repair. METHODS: All eyes with NK at Wills Eye Hospital following RRD repair from June 1, 2011, to December 1, 2020 were included. Patients with prior ocular procedures (other than cataract surgery), herpetic keratitis, and diabetes mellitus were excluded. RESULTS: During the study period, 241 patients were diagnosed with NK, and 8179 eyes underwent RRD surgery, giving a 9-year prevalence rate of 0.1% (95% CI, 0.1%-0.2%). Mean age was 53.4 ± 16.6 years during RRD repair and 56.5 ± 13.4 years during NK diagnosis. Mean time to NK diagnosis was 3.0 ± 5.6 years (range, 6 days to 18.8 years). Mean visual acuity before NK was 1.10 ± 0.56 logMAR (20/252 Snellen), and it was 1.01 ± 0.62 logMAR (20/205 Snellen) at final visit (p = 0.75). Six eyes (54.5%) developed NK <1 year following RRD surgery. Mean final visual acuity was 1.01 ± 0.53 logMAR (20/205 Snellen) in this group versus 1.01 ± 0.78 logMAR (20/205 Snellen) in the delayed NK group (p = 1.00). CONCLUSIONS: NK may present acutely or up to several years following surgery, with severity of corneal defects ranging from stage 1 to stage 3 NK. Surgeons should be mindful of the potential for this rare complication following RRD repair.

Pars Plana Vitrectomy for Idiopathic Epiretinal Membrane: OCT Biomarkers of Visual Outcomes in 322 Eyes.

OBJECTIVE: To investigate OCT-based biomarkers of visual acuity (VA) in eyes with idiopathic epiretinal membranes (ERMs) undergoing surgical intervention. PURPOSE: To assess the surgical outcomes of pars plana vitrectomy (PPV) and membrane peel (MP) surgery in eyes with idiopathic ERM and to identify potential imaging-based biomarkers of vision outcomes. METHODS: Retrospective, consecutive case series of eyes with idiopathic ERM that underwent PPV and MP surgery between January 1, 2017, and January 1, 2019. A previously described ERM grading scale was utilized for OCT analysis. The primary outcome was VA at postoperative month 6 and at final follow-up. The secondary outcome was the association of OCT structural features, including ectopic inner foveal layers (EIFLs), inner microcystoid changes, and ellipsoid zone (EZ) disruption, with VA outcomes. RESULTS: A total of 322 eyes with idiopathic ERM were included. The mean (± standard deviation) follow-up was 506.6 ± 324.6 days after MP surgery. VA improved from logarithm of the minimal angle of resolution value of 0.49 ± 0.27 (Snellen 20/61) before MP surgery to 0.41 ± 0.30 (Snellen 20/51, P < 0.001) at 6 months after MP surgery and to 0.31 ± 0.29 (Snellen 20/41, P < 0.001) at the final follow-up. A total of 21 (6.5%) eyes were graded as stage 1, 38 (11.8%) as stage 2, 188 (58.4%) as stage 3, and 75 (23.3%) as stage 4, with higher ERM stages associated with worse pre-MP VA (P < 0.001). The presence of inner microcystoid changes was associated with worse pre-MP VA (P = 0.04). Stage 4 ERM characteristics (P = 0.03), the presence of EZ disruption (P = 0.01) at month 3, and the presence of inner microcystoid changes at month 3 (P = 0.02) were associated with worse VA at 6 months. The presence of EIFL was not associated with the 6-month or final VA on multivariate analysis. When analyzed within defined age groups, patients older than 80 years had worse final VA (P = 0.02) and were more likely to have inner microcystoid changes on OCT (P = 0.01). CONCLUSIONS: VA improvement was noted after surgery in eyes with idiopathic ERM across all stages. Preoperative stage 4 characteristics were associated with worse VA at 6 months. Postoperative inner microcystoid changes and EZ disruption at month 3 were additional OCT biomarkers associated with worse 6-month and final VA outcomes.

Factors Associated With Good Visual Acuity Outcomes After Retinectomy in Eyes With Proliferative Vitreoretinopathy.

PURPOSE: To investigate factors associated with good visual acuity (VA) following repair of rhegmatogenous retinal detachments (RD) with proliferative vitreoretinopathy (PVR) undergoing retinectomy. DESIGN: Interventional, retrospective, case-control study. METHODS: This single-institution study evaluated patients who underwent retinectomy during repair of RD with PVR from January 1, 2015 to December 31, 2019. A good VA cohort was identified based on a final VA ≥20/70. A 2:1 age-matched and gender-matched poor VA cohort with VA <20/70 was subsequently identified. Metrics compared between the two cohorts included time from primary and recurrent RD diagnosis to surgery, lens status, initial RD size, macula involvement, PVR grade, and size of retinectomy. RESULTS: A total of 5355 eyes were diagnosed with primary RD during the study period, of which 345 had PVR and underwent retinectomy. The good VA cohort included 62 eyes with a mean final logMAR VA of 0.32 [Snellen 20/42], while the poor VA cohort included 119 eyes with a mean final logMAR VA of 1.54 [Snellen 20/693; P < .0001]. On multivariate analysis, smaller initial RD size (P = .0090), fewer surgeries (P = .0002), shorter time between recurrent RD diagnosis and subsequent surgeries (P = .0006), better preoperative VA (P = .0276), and pseudophakia at final visit (P = .0049) remained significant predictors of good vision. CONCLUSION: Eyes undergoing retinectomy during repair of RD with PVR can achieve good VA outcomes. The primary modifiable factor associated with better VA was shorter delay between redetachment diagnosis and surgery, particularly in the absence of silicone oil tamponade.

Epiretinal Membrane Surgery after Retinal Detachment Repair: Visual Acuity Outcomes and OCT Analysis.

PURPOSE: To assess visual acuity (VA) outcomes of epiretinal membrane (ERM) surgery following primary rhegmatogenous retinal detachment (RD) repair and to identify OCT features predictive of visual outcomes. DESIGN: Retrospective, consecutive case series. SUBJECTS: Eyes undergoing pars plana vitrectomy (PPV) with membrane peel (MP) surgery for ERM following primary RD repair (PPV with or without scleral buckle (SB) and gas tamponade). METHODS: Retrospective chart review from 2015 to 2018. A previously described ERM grading scale was utilized for OCT structural analysis. MAIN OUTCOME MEASURES: Visual acuity (VA) and change in VA from pre- MP to 6 months and final follow-up. Secondary outcomes included RD and OCT features predictive of VA, as well as RD factors associated with need for subsequent MP surgery. RESULTS: 53 eyes of 53 patients underwent MP following RD repair. VA improved significantly from logMAR 1.00 ± 0.51 (Snellen 20/200) pre-MP to 0.45 ± 0.41 (20/56) at 6 months and 0.42 ± 0.41 (20/53) at final follow-up, (p<0.001) for each respectively. Macula on eyes had better 6 month [0.29 ± 0.18 (20/39) vs. 0.51 ± 0.46 (20/65), p=0.02] and final VA [0.29 ± 0.14 (20/39) vs. 0.46 ± 0.47 (20/58), p=0.04] after MP surgery. VA improved significantly from pre-MP to 6 months and final follow-up regardless of macula status. MP occurring ≤180 days from RD repair and IS/OS loss were associated with worse pre-MP VA [1.13 ± 0.09 (20/270) vs. 0.82 ± 0.07(20/132), p=0.01 and 1.21 ± 0.07 (20/324) vs. 0.74 ± 0.09 (20/110) p=0.0003, respectively]. IS/OS loss [adjusted means 0.54 ± 0.07 (20/69) vs. 0.25 ± 0.08 (20/36) at final visit, p=0.006] and RD repair with PPV/SB [0.53 ± 0.08 (20/68) vs. 0.31 ±0.07 (20/41) at final visit, p=0.03] were significantly associated with worse VA at both 6 months and final follow-up. CONCLUSIONS: Eyes undergoing MP after RD repair have significant visual acuity gains independent of macula-status at time of RD repair. Pre-operative IS/OS disruption was the OCT feature best predictive of visual acuity.

When ophthalmology goes virtual amid a pandemic: content analysis of the 2020 #ASCRSVirtualMeeting.

PURPOSE: To assess the use and impact of the social media platform Twitter during the 2020 ASCRS Virtual Meeting. SETTING: Social media platform Twitter.com. DESIGN: Retrospective review. METHODS: Retrospective analysis of Twitter use during the ASCRS Virtual Meeting in May 2020. All tweets and associated metadata pertaining to the conference were compiled starting from when the virtual meeting was announced (April 8, 2020) to 2 weeks postconference (May 31, 2020). Two coders independently coded all tweets and excluded tweets if they were irrelevant or no longer available. RESULTS: A total of 501 tweets were reviewed, of which 48.5% of tweets came from private accounts, 23.1% from academic institutions, 14.4% from ASCRS accounts, 12.4% from industry, and 1.6% from professional organizations; 146 tweets (29.1%) were shared before, 303 tweets (60.5%) during, and 52 tweets (10.4%) after the conference. A total of 315 tweets (62.9%) promoted conference events, 137 tweets (27.3%)) were about research studies, 136 tweets (27.1%) were social posts, 115 tweets (23.0%) were from industry sponsors, 22 tweets (4.4%) were self-promotion, and 5 tweets (1.0%5) were not categorized. Twitter impressions on the ASCRS account increased by 79% in 2020 compared with the 2019 annual meeting. CONCLUSIONS: To the author's knowledge, this is the first study to describe how Twitter users engaged with a virtual ophthalmology meeting through social media during the coronavirus pandemic. Findings from this study offer insight into how the ophthalmology community can use social media during conferences and highlight opportunities for networking through social media for both virtual and in-person conferences in the future.

The role of bioidentical hormone replacement therapy in anti-aging medicine: a review of the literature.

The changes in skin and overall appearance that occur with increasing age can be partly attributed to declining hormone levels. While hormonal deficiencies are most commonly associated with postmenopausal females, males are also subject to age-related testosterone decline and may benefit from replacement of deficient hormones. However, great disparities exist between the recommendations of scientific societies and actual use of hormone supplements in aging patients. The purpose of this literature review is to discuss the role of hormones in the aging process of the skin, explain the safety profile of hormone replacement therapy, specifically discussing the superiority of bioidentical hormones, and highlight the benefits of hormone replacement in anti-aging of the skin. In summary, this literature review suggests that hormone replacement with bioidentical hormones is a safe and effective way to prevent skin aging.

Practice Patterns and Responsiveness to Simulated Common Ocular Complaints Among US Ophthalmology Centers During the COVID-19 Pandemic.

IMPORTANCE: The coronavirus disease 2019 (COVID-19) pandemic has drastically changed how comprehensive ophthalmology practices care for patients. OBJECTIVE: To report practice patterns for common ocular complaints during the initial stage of the COVID-19 pandemic among comprehensive ophthalmology practices in the US. DESIGN, SETTING, AND PARTICIPANTS: In this cross-sectional study, 40 private practices and 20 university centers were randomly selected from 4 regions across the US. Data were collected on April 29 and 30, 2020. INTERVENTIONS: Investigators placed telephone calls to each ophthalmology practice office. Responses to 3 clinical scenarios-refraction request, cataract evaluation, and symptoms of a posterior vitreous detachment-were compared regionally and between private and university centers. MAIN OUTCOMES AND MEASURES: The primary measure was time to next appointment for each of the 3 scenarios. Secondary measures included use of telemedicine and advertisement of COVID-19 precautions. RESULTS: Of the 40 private practices, 2 (5%) were closed, 24 (60%) were only seeing urgent patients, and 14 (35%) remained open to all patients. Of the 20 university centers, 2 (10%) were closed, 17 (85%) were only seeing urgent patients, and 1 (5%) remained open to all patients. There were no differences for any telemedicine metric. University centers were more likely than private practices to mention preparations to limit the spread of COVID-19 (17 of 20 [85%] vs 14 of 40 [35%]; mean difference, 0.41; 95% CI, 0.26-0.65; P < .001). Private practices had a faster next available appointment for cataract evaluations than university centers, with a mean (SD) time to visit of 22.1 (27.0) days vs 75.5 (46.1) days (mean difference, 53.4; 95% CI, 23.1-83.7; P < .001). Private practices were also more likely than university centers to be available to see patients with flashes and floaters (30 of 40 [75%] vs 8 of 20 [40%]; mean difference, 0.42; 95% CI, 0.22-0.79; P = .01). CONCLUSIONS AND RELEVANCE: In this cross-sectional study of investigator telephone calls to ophthalmology practice offices, there were uniform recommendations for the 3 routine ophthalmic complaints. Private practices had shorter times to next available appointment for cataract extraction and were more likely to evaluate posterior vitreous detachment symptoms. As there has not been a study examining these practice patterns before the COVID-19 pandemic, the relevance of these findings on public health is yet to be determined.
