Enhanced durability and evolution of retreatment criteria of intravitreal antivascular endothelial growth factor agents for diabetic macular edema.

PURPOSE OF REVIEW: The increasing prevalence of diabetic macular edema (DME) necessitates an updated review of treatment modalities. While the shift from laser to anti-vascular endothelial growth factor (anti-VEGF) therapy has transformed patient outcomes, benefits of these agents are not fully realized in real-world implementation relative to the setting of controlled clinical trials. This review outlines the evolution of intravitreal anti-VEGF treatment extension protocols for DME that reflect efforts to address treatment adherence challenges while optimizing visual outcomes. RECENT FINDINGS: Recent studies highlight the efficacy of extended-interval dosing with anti-VEGF agents in managing DME. Trials such as RISE/RIDE, VISTA/VIVID, and LUCIDATE have established the foundation of these regimens by demonstrating sustained visual gains with continuous treatment. However, newer trials including PROTOCOL T, KESTREL/KITE, YOSEMITE/RHINE, and PHOTON have furthered this concept, revealing that less frequent dosing of various anti-VEGF agents can maintain similar visual acuity and anatomical outcomes to traditional monthly injections. SUMMARY: The reviewed findings suggest a paradigm shift in DME treatment toward less frequent anti-VEGF injections. This has significant implications for clinical practice, potentially leading to greater adherence to treatment regimens and sustained visual function in patients, while minimizing treatment burden and healthcare costs. Further investigation into the long-term effects of extended dosing intervals is required.

Elevated HbA1c is not associated with reoperation following arthroscopic rotator cuff repair in patients with diabetes mellitus.

BACKGROUND: Hyperglycemia is a known risk factor for tendon degeneration due to oxidative stresses from production of advanced glycosylation end products. In patients with diabetes mellitus (DM), analysis of glycated hemoglobin (HbA1c) provides a 3-month window into a patient's glucose control. No guidelines exist for ideal preoperative HbA1c and glucose control prior to arthroscopic rotator cuff repair. This study evaluated if a critical HbA1c level is associated with reoperation following arthroscopic rotator cuff repair. METHODS: We retrospectively evaluated patients with DM who underwent primary arthroscopic rotator cuff repair from January 2014 to December 2018 at a single institution. Patients required a preoperative HbA1c within 3 months of surgery. Medical records were queried to evaluate for reoperation and identify the subsequent procedures performed. Univariate statistical analysis was performed to assess factors associated with reoperation (P < .05 considered significant). Threshold, area under the curve (AUC), analysis was performed to assess if a critical HbA1c value was associated with reoperation. RESULTS: A total of 402 patients met inclusion criteria. Patients had an average age of 65.5 years (range 40-89) at time of surgery; 244 (60.6%) patients were male; and average body mass index was 32.96 ± 5.81. Mean HbA1c was 7.36 (range 5.2-12). Thirty-three patients (8.2%) underwent subsequent reoperation. Six patients (1.5%) underwent capsular release and lysis of adhesions, 20 patients (5.0%) underwent a revision rotator cuff surgery, combination revision rotator cuff repair and lysis of adhesions, graft-augmented revision repair, or superior capsular reconstruction, and 7 patients (1.7%) underwent revision to reverse shoulder arthroplasty (1.7%). There were no cases of reoperation for infection. On AUC analysis, no critical HbA1c value was identified to predispose to reoperation. Interestingly, elevated preoperative American Society of Anesthesiologists (ASA) physical status classification score (2.8 vs. 2.28, P = .001) was associated with a higher reoperation rate. DISCUSSION: In patients with DM, preoperative HbA1c is not a predictive factor for surgical failure requiring reoperation. Stable glycemic control is important to a patient's overall health and may play a role in minimizing postoperative medical complications, but an elevated preoperative HbA1c should not be a strict surgical contraindication for arthroscopic rotator cuff repair. In patients with DM, an elevated ASA score is associated with an increased rate of subsequent reoperation; diabetic patients should be counseled accordingly.

Management of proximal humerus bone loss with allograft prosthetic composite technique in shoulder arthroplasty.

BACKGROUND: Proximal humerus bone loss in shoulder arthroplasty is a difficult problem with limited treatment options. It most commonly occurs in the setting of a previously failed shoulder arthroplasty; however, it is occasionally encountered in cases of primary shoulder arthroplasty. Reconstruction of the proximal humerus is essential for soft tissue tension for implant stability and maximizing function. The purpose of this study was to analyze the clinical and functional outcomes of the allograft prosthetic composite (APC) technique for the management of proximal humeral bone loss in shoulder arthroplasty. METHODS: A retrospective review was performed of all patients who underwent primary or revision shoulder arthroplasty using an APC technique with a reverse shoulder arthroplasty prosthesis for the management of proximal humerus bone loss. Data collected included demographic variables, previous shoulder surgeries, indication for APC, type of allograft utilized, fixation technique, and reoperation and revision rates. Patients were contacted by phone and/or email survey to obtain the latest patient-reported functional outcome scores. RESULTS: We identified 14 patients who underwent shoulder arthroplasty using the APC technique with a reverse shoulder arthroplasty prosthesis. One (7.1%) was performed as a primary arthroplasty, and 13 (92.9%) were performed as revision arthroplasties. The indications for APC were instability (21.4%), periprosthetic fracture (21.4%), periprosthetic joint infection (14.3%), humeral component loosening (14.3%), rotator cuff failure (14.3%), fracture sequelae (7.1%), and failed hemiarthroplasty (7.1%). In terms of allograft type, 10 (71.4%) were performed with proximal femur allograft and 4 (28.6%) with proximal humerus allograft. There were 6 patients (42.9%) who sustained postoperative complications, 5 patients (35.7%) had instability, and 1 (7.1%) patient had postoperative wound drainage. All patients with a complication required a revision arthroplasty. CONCLUSION: The APC technique used to address proximal humerus bone loss in shoulder arthroplasty has a high complication rate with fair patient-reported functional outcome scores. Most of the postoperative complications and reoperations are related to implant instability.

Virtual versus In-Person Ophthalmology Interviews: Perceptions of U.S. Ophthalmology Fellowship Applicants in 2022-2023.

Purpose Despite easing restrictions on social distancing and travel since the beginning of coronavirus disease 2019 pandemic, virtual interviews remain a widely used format for ophthalmology fellowship interviews. This study aims to evaluate the relative benefits and drawbacks of in-person versus virtual interviews during a cycle where both formats were prevalent. Methods A prospective cross-sectional study surveyed all fellowship applicants ( N = 311) who applied to Wills Eye Hospital and Bascom Palmer Eye Institute during the 2022 to 2023 application cycle. Results A total of 59 (19%) applicants responded to the survey, with the majority being male (53.0%) and between the ages of 20 and 35 (91.3%). There was no statistically significant difference between the number of virtual and in-person interviews attended or the total number of interviews attended. The highest ranked limitations of the virtual interview process were limited exposure to details of the program structure, limited opportunity to exhibit applicants' strengths to the program, and limited exposure to the fellows. The highest ranked strengths were less pressure during interviews, greater scheduling flexibility, and ability to interview at more fellowship programs. The highest ranked limitations of the in-person interview process were more pressure during interviews, inability to interview at all desired fellowship programs, and decreased scheduling flexibility. The highest ranked strengths based on median rankings were greater exposure to details of the program structure, greater ability to exhibit an applicant's strengths to the program, and greater exposure to the geographic location/city. Conclusion While both in-person and virtual interviews have their own benefits and limitations, virtual interviews appear to be more cost-effective and time-efficient while in-person interviews provide better opportunities to assess program fit and culture. A hybrid format that combines the ideal aspects of both formats may be an optimal solution.

Correlation of Complement Activation in Aqueous and Vitreous in Patients With Proliferative Diabetic Retinopathy.

Purpose: A growing body of evidence suggests complement dysregulation is present in the vitreous of patients with diabetic eye disease. Further translational study could be simplified if aqueous-as opposed to vitreous-were used to sample the intraocular complement environment. Here, we analyze aqueous samples and assess whether a correlation exists between aqueous and vitreous complement levels. Methods: We collected aqueous, vitreous, and plasma samples from patients with and without proliferative diabetic retinopathy (PDR) undergoing vitrectomy. We assessed correlation between complement levels in aqueous and vitreous samples after using a normalizing ratio to correct for vascular leakage. Spearman correlation coefficients were used to assess the correlation between complement levels in the aqueous and vitreous. Results: Aqueous samples were obtained from 17 cases with PDR and 28 controls. In all patients, aqueous Ba, C3a, and albumin levels were strongly correlated with vitreous levels (Spearman correlation coefficient of 0.8 for Ba and C3a and 0.7 for albumin; all P values < 0.0001). In PDR eyes only, aqueous and vitreous C3a levels were significantly correlated (Spearman correlation coefficient 0.7; P = 0.002), whereas in control eyes, both Ba and C3a (Spearman correlation coefficients of 0.7; P < 0.0001) were significantly correlated. Conclusions: A strong correlation exists between aqueous and vitreous complement levels in diabetic eye disease. Translational Relevance: The results establish that accurate sampling of the intraocular complement can be done by analyzing aqueous specimens, allowing for the rapid and safe measurement of experimental complement targets and treatment response.

Narcotic requirements after shoulder arthroplasty are low using a multimodal approach to pain.

BACKGROUND: Recent "multimodal" approaches to pain, although understudied, have shown promise in reducing reliance on narcotics in shoulder arthroplasty (SA). Many surgeons report being unsure of how many narcotic pills to prescribe after the surgery. As result, patients are prescribed upwards of 60 oxycodone 5-mg pills for a 6-to-12-week treatment period despite studies showing postoperative pain can be managed without any medication at all. PURPOSE: The purpose of this multicenter study was to prospectively determine the number of opiate pills required after SA to develop generalizable, evidence-based prescription guidelines for surgeons. We hypothesized that opioid prescription would be low using a multimodal approach to pain management. METHODS: The study enrolled 63 patients undergoing SA. Subjects received either an interscalene nerve block with liposomal bupivacaine, standard bupivacaine, or a local infiltration standard bupivacaine field block based on preference. All subjects were provided with postoperative "Pain Journals" to document their daily pain on a Numerical Rating Scale and daily opioid consumption during the 14-day postoperative period. RESULTS: Overall, patients consumed an average of 8.6 oxycodone 5-mg pills (64.5 morphine milligram equivalents) after SA. Seventy-nine percent of patients required 15 or fewer oxycodone 5-mg pills, and 27% successfully managed their postoperative pain with zero opioids. Average pain remained low for patients in all groups. CONCLUSION: With a multimodal approach, most patients undergoing SA can manage postoperative pain with 15 or fewer oxycodone 5-mg tablets, or 112.5 morphine milligram equivalents. The addition of a liposomal bupivacaine interscalene nerve block may further reduce the consumption of postoperative narcotics compared with a standard interscalene nerve block. This study provides evidence that may be used for surgeon guidelines in the effort to reduce opioid prescriptions after SA.

Opioid requirement after rotator cuff repair is low with a multimodal approach to pain.

BACKGROUND: Current practices may aim to blunt rather than understand postoperative pain. Perhaps the most common serious complication of arthroscopic rotator cuff repair (ARCR) is persistence of opiate medication intake. Patients still receive upwards of 80 oxycodone 5 mg pills, or 600 morphine milligram equivalents (MMEs), leading more than 20% of opioid-naïve subjects to continue to fill opioid prescriptions beyond 180 days after surgery. Developing evidence-based guidelines for narcotic prescription after ARCR presents an opportunity for orthopedic surgeons to address the opioid epidemic. PURPOSE: The purpose of this study was (1) to prospectively determine the requirements for opiate medications after ARCR, and (2) to create an evidence-based guideline for postoperative prescription, in contrast to the anecdotal or expert panel recommendations that currently exist. We further investigated whether a liposomal bupivacaine (LB) interscalene never block (ISNB) would reduce pain and opiate consumption compared with standard bupivacaine ISNB (control) for ARCR. METHODS: The study enrolled 100 patients who underwent primary ARCR surgery. Patients were provided with postoperative "pain journals" to document their daily pain on a numerical rating scale, satisfaction with pain management using the Likert scale, and track their daily oxycodone 5 mg pill consumption during the 14-day postoperative period. Enrolled patients were further randomized to receiving an LB (experimental) or standard bupivacaine (control) ISNB. RESULTS: A total of 77% of all patients required fewer than 15 pills postoperatively. The LB group consumed an average of 1.7 fewer pills (13.0 MMEs) on postoperative day (POD) 1 (P = .02) and reported statistically lower pain during PODs 1 and 2 (P = .01 and P = .006), as well as cumulatively throughout the study period (P = .03). In addition, LB patients remained opioid-free at a higher rate (44% vs. 15% in controls, P = .03). CONCLUSION: With a multimodal approach, the majority of patients undergoing ARCR can manage postoperative pain with 15 or fewer oxycodone 5 mg tablets (112.5 MMEs) and maintain a high degree of satisfaction. The addition of an LB ISNB may further reduce the consumption of postoperative narcotics compared with a standard ISNB. This study provides evidence that may be used for surgeon guidelines in the effort to reduce opioid prescriptions after ARCR.

Opioid Consumption After Knee Arthroscopy.

PURPOSE: To prospectively observe opioid consumption in patients undergoing knee arthroscopy and to create an evidence-based guideline for opioid prescription. METHODS: This prospective multicenter observational study enrolled patients undergoing outpatient knee arthroscopy for meniscal repair, meniscectomy, or chondroplasty. Patients were provided with a pain journal to record postoperative opioid consumption, Numeric Pain Rating Scale (NPRS) pain scores, and Likert scale satisfaction scores for 1 week postoperatively. State databases were reviewed for additional opioid prescriptions. RESULTS: One hundred patients were included in this study. Patients were prescribed a median of 5 pills (37.5 oral morphine equivalent [OME]). Median postoperative opioid consumption was 0 pills, with a mean of 0.6 pills (4.4 OME), and 74% of patients did not consume any opioid medication postoperatively. All patients consumed ≤5 pills (37.5 OME), and no patient required a refill. Patients reported a mean daily NPRS value of 1.9 out of 10 and a mean Likert score of 4.4 out of 5. CONCLUSION: We found that current opioid prescribing habits exceed the need for postoperative pain management. Overall, all patients consumed ≤5 opioid pills, and 92% of patients discontinued opioids by the second postoperative day. In spite of the low prescription quantity, patients reported high satisfaction rates and low NPRS pain scores and required no refills. Therefore, we recommend that patients undergoing knee arthroscopy are prescribed no more than 5 oxycodone 5-mg pills. LEVEL OF EVIDENCE: II, prospective prognostic cohort investigation.

Complement Activation in the Vitreous of Patients With Proliferative Diabetic Retinopathy.

Purpose: A growing body of evidence points to complement dysregulation in diabetes. Early studies have indicated the presence of complement components inside the eye in patients with diabetic retinopathy, but these data have been confounded by leakage of proteins from the systemic circulation into the vitreous cavity. Methods: We took samples of plasma and vitreous from patients with and without proliferative diabetic retinopathy (PDR) and measured levels of 16 complement components as well as albumin. We employed a normalized ratio using local and systemic complement and albumin levels to control for vascular leakage into the vitreous cavity. Results: Before normalizing, we found significantly higher levels of 16 complement components we measured in PDR eyes compared to controls. After normalizing, levels of C4, factor B, and C5 were decreased compared to controls, while C3a and Ba levels were elevated compared to controls. We also found higher ratios of C3a/C3, C5a/C5, and Ba/factor B in PDR eyes compared to controls. Conclusions: We found evidence of local, intraocular activation of C3, C5, and factor B. The normalized data suggest involvement of the alternative complement pathway. By showing activation of specific complement components in PDR, this study identifies targets for diagnostic and therapeutic potential.

Opioid Use After Knee Arthroscopy.

PURPOSE: To quantify the use of 5 mg oxycodone by patients who have undergone knee arthroscopy. METHODS: Patients who underwent knee arthroscopy at 2 institutions between May 2018 and May 2019 were identified retrospectively. Patients were called and queried about the following metrics: total postoperative opioid consumption, preoperative opioid consumption (defined as within 3 months of surgery), smoking status, and history of depression. The total number of opioids prescribed and number of refills were determined according to each patient's chart. State databases were reviewed for additional opioid prescriptions. RESULTS: A total of 100 patients were included in this study. Patients were prescribed a median of 5 pills (range, 5 to 40). Median postoperative opioid consumption was 0 pills, with a mean of 1.9 pills (14.3 oral morphine equivalents) and a range of 0 to 25 pills of oxycodone 5 mg. Of the patients, 97% did not obtain refills, and 58% of the patients did not consume any opioids. Overall, 90% of all patients consumed ≤ 5 pills. CONCLUSIONS: Of the patients, 90% o consumed 5 or fewer opioid pills (oxycodone 5 mg) following knee arthroscopy, with more than half of the patients consuming 0 pills. As a result, we recommend that 5 oxycodone 5 mg pills serve as an objective guideline for opioid prescription following knee arthroscopy. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Liposomal bupivacaine reduces opiate consumption after rotator cuff repair in a randomized controlled trial.

BACKGROUND: Arthroscopic rotator cuff repair (ARCR) provides excellent clinical outcomes but is often associated with significant postoperative pain. The use of intraoperative anesthesia in conjunction with multimodal pharmacologic strategies is a widely accepted approach for managing surgical pain and reducing opiate use. The purpose of this study was to determine whether using a combined field and suprascapular nerve block with liposomal bupivacaine (LB) in addition to an interscalene block would provide greater pain relief and a reduction in opiate consumption compared with an interscalene block alone. METHODS: The study enrolled 50 patients with full-thickness rotator cuff tears undergoing primary ARCR surgery. Patients were randomized to receive intraoperative LB (n = 25) or not (n = 25) and given postoperative "pain journals" to document visual analog scale pain scores and to track their daily opioid consumption during the first 5 postoperative days. RESULTS: Patients in the LB group reported statistically and clinically lower pain scores during postoperative days 1 and 2 (P < .0001 and P = .03, respectively). In addition, patients in the LB group consumed significantly fewer narcotics than the control group during the 5-day period, demonstrating a 64% reduction in total narcotic consumption (P = .002). CONCLUSION: The findings of this study suggest that the addition of LB to multimodal anesthetic protocols significantly reduces the acute perioperative pain experienced following rotator cuff repair and the number of narcotic pills consumed in the first 5 days after ARCR. Furthermore, the findings provide guidelines for postoperative narcotic prescribing to reduce the quantity of opiates prescribed.
