RESUMO

PURPOSE: To review changes in the provision of charity eye care in the past 50 years with hypothesized resulting effects on surgical training and patient outcomes. DESIGN: Perspective. METHODS: Case report, comparison of experience in community and training program settings, and selected literature review. RESULTS: The population to which charity care applies has shrunk as broader insurance coverage has been legislated, but in 2023 remains at approximately 7.3% of the US population. In areas with ophthalmology training programs, house staff supervised by faculty provide most of the charity care. In areas without training programs, a shrinking pool of willing private practitioners provides charity care. Because there is no organized financial support behind provision of charity, nonanecdotal data needed to assess the problem and guide decision making are lacking. CONCLUSIONS: Charity eye care in ophthalmology in 2024 is a patchwork of transient, local efforts that have a few common themes: absent material basis for sustainability, a narrowing base of support by clinicians, transfer of care to training programs, and financial vetting of applicants by nonclinicians. Unless universal health care legislation passes, which would eliminate the issue, suggestions for improvement include broader voluntary participation by private practice ophthalmologists in charity eye care, allocation of charity care spending by nonprofit hospitals to support this effort, and clinician-determined criteria for provision of charitable surgery supported by involved hospital systems.

RESUMO

BACKGROUND: In eyes with diabetic macular edema, the relative efficacy of administering aflibercept monotherapy as compared with bevacizumab first with a switch to aflibercept if the eye condition does not improve sufficiently (a form of step therapy) is unclear. METHODS: At 54 clinical sites, we randomly assigned eyes in adults who had diabetic macular edema involving the macular center and a visual-acuity letter score of 24 to 69 (on a scale from 0 to 100, with higher scores indicating better visual acuity; Snellen equivalent, 20/320 to 20/50) to receive either 2.0 mg of intravitreous aflibercept or 1.25 mg of intravitreous bevacizumab. The drug was administered at randomization and thereafter according to the prespecified retreatment protocol. Beginning at 12 weeks, eyes in the bevacizumab-first group were switched to aflibercept therapy if protocol-specified criteria were met. The primary outcome was the mean change in visual acuity over the 2-year trial period. Retinal central subfield thickness and visual acuity at 2 years and safety were also assessed. RESULTS: A total of 312 eyes (in 270 adults) underwent randomization; 158 eyes were assigned to receive aflibercept monotherapy and 154 to receive bevacizumab first. Over the 2-year period, 70% of the eyes in the bevacizumab-first group were switched to aflibercept therapy. The mean improvement in visual acuity was 15.0 letters in the aflibercept-monotherapy group and 14.0 letters in the bevacizumab-first group (adjusted difference, 0.8 letters; 95% confidence interval, -0.9 to 2.5; P = 0.37). At 2 years, the mean changes in visual acuity and retinal central subfield thickness were similar in the two groups. Serious adverse events (in 52% of the patients in the aflibercept-monotherapy group and in 36% of those in the bevacizumab-first group) and hospitalizations for adverse events (in 48% and 32%, respectively) were more common in the aflibercept-monotherapy group. CONCLUSIONS: In this trial of treatment of moderate vision loss due to diabetic macular edema involving the center of the macula, we found no evidence of a significant difference in visual outcomes over a 2-year period between aflibercept monotherapy and treatment with bevacizumab first with a switch to aflibercept in the case of suboptimal response.

RESUMO

PURPOSE: To report updated clinical outcomes in subjects undergoing pars plana vitrectomy (PPV) using modern techniques and equipment for the treatment of proliferative diabetic retinopathy-related complications. Pooled analysis of five randomized clinical trials conducted at the same institution and included both study and control subjects from the trials. METHODS: There were 943 subjects who prospectively underwent small-gauge PPV with antivascular endothelial growth factor pretreatment for proliferative diabetic retinopathy-related complications and completed 6-month follow-up. RESULTS: The visual acuity of the study population improved from median 2.00 (interquartile range 1.3, 2.3) at baseline to median 1.00 (interquartile range 0.5, 1.3) at 6 months. One hundred and eighty-four patients (19.5%) achieved 20/50 or better acuity, and 652 patients (69.1%) achieved 20/200 or better acuity at 6 months. The vision improved or remained stable in 901 patients (95.5%), and 11 patients (1.2%) developed no light perception at 6 months. Intraoperative complications occurred in 343 cases (36.4%), and 199 cases (21.1%) experienced a postoperative complication. The most common postoperative complication was vitreous hemorrhage in 124 cases (62.3% of all complications). Unplanned secondary PPV was necessary in 86 cases (9.1%). CONCLUSION: This study reports updated clinical outcomes in patients undergoing PPV for proliferative diabetic retinopathy-related complications which compares favorably with the age before small-gauge PPV and antivascular endothelial growth factor pretreatment.

RESUMO

PURPOSE: To evaluate whether topical acrizanib (LHA510), a small-molecule vascular endothelial growth factor receptor inhibitor, could suppress the need for anti-vascular endothelial growth factor therapy over a 12-week period in patients with neovascular age-related macular degeneration. DESIGN: A phase 2 multicenter randomized double-masked, vehicle-controlled proof-of-concept study. METHODS: Trial includes n = 90 patients with active choroidal neovascularization due to neovascular age-related macular degeneration and under anti-vascular endothelial growth factor treatment. All patients received an intravitreal injection of ranibizumab at baseline and were retreated when there was evidence of disease recurrence (rescue). Patients were randomized 1:1 to receive topical LHA510 or vehicle for 12 weeks. Drops were administered twice a day for 8 weeks and then 3 times a day for the last 4 weeks. MAIN OUTCOME MEASURE: The primary outcome was the number of patients requiring rescue over 84 days of topical dosing. Key secondary outcome measures were time to first rescue, total number of ranibizumab injections, changes in central subfield thickness, and changes of visual acuity from baseline to day 84. RESULTS: The extended per protocol set included 70 patients of whom 25 of 33 patients in the LHA510 group (75.8%) and 25 of 37 patients in the placebo group (67.6%) required rescue by day 84 (P = .8466). Secondary and subgroup analysis did not support evidence of efficacy. Twenty-one of 46 patients administered LHA510 developed a reversible corneal haze that resolved with cessation of treatment and did not recur in patients restarted at once daily frequency. CONCLUSION: In spite of extensive optimization for topical efficacy, LHA510 failed to demonstrate clinical efficacy.

RESUMO

PURPOSE: To describe the rationale for revising the hydroxychloroquine (HCQ) dosing and screening guidelines and to identify the barriers to more effective guidelines in the future. DESIGN: Literature review. METHODS: A PubMed query of studies on HCQ dosing and HCQ retinopathy (HCQR) screening was conducted with a selective review of the English language literature. RESULTS: Three iterations of the American Academy of Ophthalmology HCQ dosing and HCQR screening guidelines have been published without including prescribing physicians on the writing committees. This may contribute to prescribing physicians' low adherence to the guidelines. As ancillary tests have improved, asymptomatic HCQR is being detected earlier, leading to a higher reported prevalence of HCQR and a drop in the ceiling for safe dosing. These trends put stricter constraints on prescribers and their patients, who may have had well-controlled autoimmune disease on HCQ doses that were previously considered to be below the high-risk threshold for HCQR. Indeed, stopping HCQ at the earliest sign of HCQR should be reconsidered; for cases of early HCQR, dose reduction and more intensive monitoring for retinopathy may strike a more appropriate balance between HCQ risk and benefits. A prospective study using the Diabetic Retinopathy Clinical Research Retina Network with standardized collection of data, HCQ blood levels, centralized grading of ancillary tests, and community and academic ophthalmologists would provide a stronger evidence base for future HCQ guidelines. CONCLUSIONS: The HCQ dosing and screening guidelines should be updated and a prospective study of HCQ dosing and HCQR should be initiated with the joint efforts of ophthalmologists and prescribing physicians.

RESUMO

PURPOSE: To review the current therapeutic options for the management of diabetic retinopathy (DR) and diabetic macular edema (DME) and examine the evidence for integration of laser and pharmacotherapy. METHODS: A review of the PubMed database was performed using the search terms diabetic retinopathy, diabetic macular edema, neovascularization, laser photocoagulation, intravitreal injection, vascular endothelial growth factor (VEGF), vitrectomy, pars plana vitreous surgery, antiangiogenic therapy. With additional cross-referencing, this yielded 835 publications of which 301 were selected based on content and relevance. RESULTS: Many recent studies have evaluated the pharmacological, laser and surgical therapeutic strategies for the treatment and prevention of DR and DME. Several newer diagnostic systems such as optical coherence tomography (OCT), microperimetry, and multifocal electroretinography (mfERG) are also assisting in further refinements in the staging and classification of DR and DME. Pharmacological therapies for both DR and DME include both systemic and ocular agents. Systemic agents that promote intensive glycemic control, control of dyslipidemia and antagonists of the renin-angiotensin system demonstrate beneficial effects for both DR and DME. Ocular therapies include anti-VEGF agents, corticosteroids and nonsteroidal anti-inflammatory drugs. Laser therapy, both as panretinal and focal or grid applications continue to be employed in management of DR and DME. Refinements in laser devices have yielded more tissue-sparing (subthreshold) modes in which many of the benefits of conventional continuous wave (CW) lasers can be obtained without the adverse side effects. Recent attempts to lessen the burden of anti-VEGF injections by integrating laser therapy have met with mixed results. Increasingly, vitreoretinal surgical techniques are employed for less advanced stages of DR and DME. The development and use of smaller gauge instrumentation and advanced anesthesia agents have been associated with a trend toward earlier surgical intervention for diabetic retinopathy. Several novel drug delivery strategies are currently being examined with the goal of decreasing the therapeutic burden of monthly intravitreal injections. These fall into one of the five categories: non-biodegradable polymeric drug delivery systems, biodegradable polymeric drug delivery systems, nanoparticle-based drug delivery systems, ocular injection devices and with sustained release refillable devices. At present, there remains no one single strategy for the management of the particular stages of DR and DME as there are many options that have not been rigorously tested through large, randomized, controlled clinical trials. CONCLUSION: Pharmacotherapy, both ocular and systemic, will be the primary mode of intervention in the management of DR and DME in many cases when cost and treatment burden are less constrained. Conventional laser therapy has become a secondary intervention in these instances, but remains a first-line option when cost and treatment burden are more constrained. Results with subthreshold laser appear promising but will require more rigorous study to establish its role as adjunctive therapy. Evidence to support an optimal integration of the various treatment options is lacking. Central to the widespread adoption of any therapeutic regimen for DR and DME is substantiation of safety, efficacy, and cost-effectiveness by a body of sound clinical trials.

RESUMO

PURPOSE: The increasing prevalence of obesity over the past 60 years implies the need to reassess the risk of hydroxychloroquine retinopathy (HR) in obese women using the American Academy of Ophthalmology (AAO) 2016 guidelines. DESIGN: Cross-sectional study. PARTICIPANTS: Medical records of 64 patients with HR from the practices of 2 ophthalmologists, 11 of whom were women with body mass index of 30 kg/m2 or more, were reviewed. METHODS: Daily dosing based on real and ideal weight was calculated. MAIN OUTCOME MEASURE: Determine the number (and percentage) of patients given daily dosing according to real-weight and ideal-weight guidelines. RESULTS: In 4 patients (36%), daily dosing was more than 5 mg/kg based on real weight and more than 6.5 mg/kg based on ideal weight. In 4 patients (36%), daily dosing was 5 mg/kg or less based on real weight and 6.5 mg/kg or less based on ideal weight. In 3 patients (27%), daily dosing was 5 mg/kg or less based on real weight and more than 6.5 mg/kg based on ideal weight. No patient had daily dosing of more than 5 mg/kg based on real weight and 6.5 mg/kg or less based on ideal weight. CONCLUSIONS: Twenty-seven percent of cases of hydroxychloroquine retinopathy in obese women had ostensibly safe dosing based on 2016 AAO guidelines. Overdosing of obese women by 2016 AAO guidelines is not rare. Daily dosing based on the older 6.5-mg/kg ideal weight threshold is safer in women with a body mass index of 30 kg/m2 or more.

RESUMO

Importance: Intravitreous injections of antivascular endothelial growth factor agents are effective for treating diabetic macular edema (DME) involving the center of the macula (center-involved DME [CI-DME]) with visual acuity impairment (20/32 or worse). The best approach to treating patients with CI-DME and good visual acuity (20/25 or better) is unknown. Objective: To compare vision loss at 2 years among eyes initially managed with aflibercept, laser photocoagulation, or observation. Design, Setting, and Participants: Randomized clinical trial conducted at 91 US and Canadian sites among 702 adults with type 1 or type 2 diabetes. Participants had 1 study eye with CI-DME and visual acuity of 20/25 or better. The first participant was randomized on November 8, 2013, and the final date of follow-up was September 11, 2018. Interventions: Eyes were randomly assigned to 2.0 mg of intravitreous aflibercept (n = 226) as frequently as every 4 weeks, focal/grid laser photocoagulation (n = 240), or observation (n = 236). Aflibercept was required for eyes in the laser photocoagulation or observation groups that had decreased visual acuity from baseline by at least 10 letters (≥ 2 lines on an eye chart) at any visit or by 5 to 9 letters (1-2 lines) at 2 consecutive visits. Main Outcomes and Measures: The primary outcome was at least a 5-letter visual acuity decrease from baseline at 2 years. Antiplatelet Trialists' Collaboration adverse events (defined as myocardial infarction, stroke, or vascular or unknown death) were reported. Results: Among 702 randomized participants (mean age, 59 years; 38% female [n=264]), 625 of 681 (92% excluding deaths) completed the 2-year visit. For eyes with visual acuity that decreased from baseline, aflibercept was initiated in 25% (60/240) and 34% (80/236) in the laser photocoagulation and observation groups, respectively. At 2 years, the percentage of eyes with at least a 5-letter visual acuity decrease was 16% (33/205), 17% (36/212), and 19% (39/208) in the aflibercept, laser photocoagulation, and observation groups, respectively (aflibercept vs laser photocoagulation risk difference, -2% [95% CI, -9% to 5%]; relative risk, 0.88 [95% CI, 0.57-1.35; P = .79]; aflibercept vs observation risk difference, -3% [95% CI, -11% to 4%]; relative risk, 0.83 [95% CI, 0.55-1.27; P = .79]; laser photocoagulation vs observation risk difference, -1% [95% CI, -9% to 6%]; relative risk, 0.95 [95% CI, 0.64-1.41; P = .79]). Antiplatelet Trialists' Collaboration vascular events occurred in 15 (7%), 13 (5%), and 8 (3%) participants in the aflibercept, laser photocoagulation, and observation groups. Conclusions and Relevance: Among eyes with CI-DME and good visual acuity, there was no significant difference in vision loss at 2 years whether eyes were initially managed with aflibercept or with laser photocoagulation or observation and given aflibercept only if visual acuity worsened. Observation without treatment unless visual acuity worsens may be a reasonable strategy for CI-DME. Trial Registration: ClinicalTrials.gov Identifier: NCT01909791.

RESUMO

OBJECTIVE: To test whether an educational model involving patients and family members (P/F) in medical error disclosure training for interprofessional clinicians can narrow existing gaps between clinician and P/F views about disclosure. METHOD: Parallel presurveys/postsurveys using Likert scale questions for clinicians and P/F. RESULTS: Baseline surveys were completed by 91% (50/55) of clinicians who attended the workshops and 74% (65/88) of P/F from a hospital patient and family advisory council. P/F's baseline views about disclosure were significantly different from clinicians' in 70% (7/10) of the disclosure expectation items and 100% (3/3) of the disclosure vignette items. For example, compared with clinicians, P/F more strongly agreed that "patients want to know all the details of what happened" and more strongly disagreed that "patients find explanation(s) more confusing than helpful." In the medication error vignette, compared with clinicians, P/F more strongly agreed that the error should be disclosed and that the patient would want to know and more strongly disagreed that disclosure would do more harm than good (all P < 0.05). After the workshop, P/F and clinician views about information sharing, fallibility, truth telling, and threshold for disclosure showed greater concordance, with significant differences remaining in less than half of the expectation items and none of the vignette responses. DISCUSSION: Even with self-selecting clinicians, collaborative learning with P/F highlights important differences in patient and clinician baseline perspectives about medical error disclosure and brings patient and clinicians views closer together.

RESUMO

Twenty-five percent of diabetes-related vision loss stems from complications of proliferative diabetic retinopathy (PDR). Panretinal photocoagulation has been the preferred treatment of high-risk PDR for decades and more recently intravitreal injections of drugs that inhibit the actions of vascular endothelial growth factor have become popular. But despite these treatments PDR may progress uncontrollably to advanced pathologies such as traction retinal detachments (TRDs), combined traction/rhegmatogenous retinal detachments (TRD/RRDs), vitreous hemorrhages, rubeosis iridis, and traction maculopathies, which produce mild-to-severe loss of vision. TDR have long been the most common indication for PDR-related vitreoretinal surgery. Vitrectomy surgery is indicated for recent (<6 months duration) TRD involving the macula, progressive TRD that threatens the macula, and recent data suggest that chronic macula-involving TRDs (>6 months duration) may also benefit. Combined TRD/RRD represents a particularly challenging surgical condition but advances in surgical instrumentation, dissection techniques, and post-operative tamponade have produced excellent success rates. The recent development of small-gauge vitrectomy systems has persuaded most surgeons to switch platforms since these appear to produce shorter surgical times and quicker post-operative recoveries. Pre-operative injections of bevacizumab are frequently administered for persistent neovascularization to facilitate surgical dissection of pre-retinal fibrosis and reduce the incidence of post-operative hemorrhages. Recent trends toward earlier surgical intervention and expanded indications are likely to continue as surgical instrumentation and techniques are further developed.

RESUMO

Diabetic macular edema (DME) is the most common cause of vision loss in patients with diabetic retinopathy with an increasing prevalence tied to the global epidemic in type 2 diabetes mellitus. Its pathophysiology starts with decreased retinal oxygen tension that manifests as retinal capillary hyperpermeability and increased intravascular pressure mediated by vascular endothelial growth factor (VEGF) upregulation and retinal vascular autoregulation, respectively. Spectral domain optical coherence tomography (SD-OCT) is the cornerstone of clinical assessment of DME. The foundation of treatment is metabolic control of hyperglycemia and blood pressure. Specific ophthalmic treatments include intravitreal anti-VEGF drug injections, intravitreal corticosteroid injections, focal laser photocoagulation, and vitrectomy, but a substantial fraction of eyes respond incompletely to all of these modalities resulting in visual loss and disordered retinal structure and vasculature visible on SD-OCT and OCT angiography. Efforts to close the gap between the results of interventions within randomized clinical trials and in real-world contexts, and to reduce the cost of care increasingly occupy innovation in the social organization of ophthalmic care of DME. Pharmacologic research is exploring other biochemical pathways involved in retinal vascular homeostasis that may provide new points of intervention effective in those cases unresponsive to current treatments.

RESUMO

OBJECTIVE: To conduct a needs assessment to identify gaps in communication skills training in ophthalmology residency programs and to use these results to pilot a communication workshop that prepares residents for difficult conversations. DESIGN: A mixed-methods design was used to perform the needs assessment. A pre-and postsurvey was administered to workshop participants. SETTING: Mass Eye and Ear Infirmary, Harvard Medical School (HMS), Department of Ophthalmology. PARTICIPANTS: HMS ophthalmology residents from postgraduate years 2-4 participated in the needs assessment and the workshop. Ophthalmology residency program directors in the United States participated in national needs assessment. METHODS: Ophthalmology program directors across the United States were queried on their perception of resident communication skills training through an online survey. A targeted needs assessment in the form of a narrative exercise captured resident perspectives on communication in ophthalmology from HMS residents. A group of HMS residents participated in the pilot workshop and a pre- and postsurvey was administered to participants to assess its effectiveness. RESULTS: The survey of program directors yielded a response rate of 40%. Ninety percent of respondents agreed that the communication skills training in their programs could be improved. Fifteen of 24 residents (62%) completed the needs assessment. Qualitative analysis of the narrative material revealed four themes; (1) differing expectations, (2) work role and environment, (3) challenges specific to ophthalmology, and (4) successful strategies adopted. Nine residents participated in the workshop. There was a significant improvement post-workshop in resident reported scores on their ability to manage their emotions during difficult conversations (p = 0.03). CONCLUSIONS: There is an opportunity to improve communication skills training in ophthalmology residency through formalized curriculum.

RESUMO

Importance: The Diabetic Retinopathy Clinical Research Network Protocol S randomized clinical trial results suggest that ranibizumab is a reasonable treatment alternative to panretinal photocoagulation (PRP) when managing proliferative diabetic retinopathy (PDR), with or without concomitant baseline diabetic macular edema (DME). However, ranibizumab injections are costly. Thus, it would be useful to examine the relative cost-effectiveness of these 2 treatment modalities. Objective: To evaluate incremental cost-effectiveness ratios of 0.5-mg ranibizumab therapy vs PRP for PDR. Design, Setting, and Participants: Preplanned secondary analysis using efficacy, safety, and resource utilization data through 2 years of follow-up at 55 US sites for 213 adults with PDR. Data were collected from February 2012 to January 2015. Interventions: Intravitreous 0.5-mg ranibizumab at baseline and as frequently as every 4 weeks based on a structured retreatment protocol or PRP at baseline for PDR. Eyes in both groups could receive ranibizumab for concomitant DME. Main Outcomes and Measures: Incremental cost-effectiveness ratios of ranibizumab compared with PRP evaluated within 2 prespecified subgroups for the study eye: with baseline vision-impairing (Snellen equivalent 20/32 or worse) DME and without baseline vision-impairing DME. Results: The study included 305 adults with PDR, the mean age was 52 years, 44% were women, and 52% were white. Of the 46 participants with PDR and vision-impairing DME at baseline, 21 were assigned to the ranibizumab group and 25 to the PRP group (plus ranibizumab for DME). Among the remaining participants without baseline vision-impairing DME, 80 and 87 were in the ranibizumab and PRP groups, respectively. For participants with and without baseline vision-impairing DME, the incremental cost-effectiveness ratios of ranibizumab therapy compared with PRP were $55 568/quality-adjusted life-year and $662 978/quality-adjusted life-year, respectively, over 2 years. Conclusions and Relevance: Over 2 years, compared with PRP, 0.5-mg ranibizumab as given in this trial is within the $50 000/quality-adjusted life-year to $150 000/quality-adjusted life-year range frequently cited as cost-effective in the United States for eyes presenting with PDR and vision-impairing DME, but not for those with PDR without vision-impairing DME.

RESUMO

BACKGROUND: Despite growing interest in engaging patients and families (P/F) in patient safety education, little is known about how P/F can best contribute. We assessed the feasibility and acceptability of a patient-teacher medical error disclosure and prevention training model. METHODS: We developed an educational intervention bringing together interprofessional clinicians with P/F from hospital advisory councils to discuss error disclosure and prevention. Patient focus groups and orientation sessions informed curriculum and assessment design. A pre-post survey with qualitative and quantitative questions was used to assess P/F and clinician experiences and attitudes about collaborative safety education including participant hopes, fears, perceived value of learning experience and challenges. Responses to open-ended questions were coded according to principles of content analysis. RESULTS: P/F and clinicians hoped to learn about each other's perspectives, communication skills and patient empowerment strategies. Before the intervention, both groups worried about power dynamics dampening effective interaction. Clinicians worried that P/F would learn about their fallibility, while P/F were concerned about clinicians' jargon and defensive posturing. Following workshops, clinicians valued patients' direct feedback, communication strategies for error disclosure and a 'real' learning experience. P/F appreciated clinicians' accountability, and insights into how medical errors affect clinicians. Half of participants found nothing challenging, the remainder clinicians cited emotions and enormity of 'culture change', while P/F commented on medical jargon and desire for more time. Patients and clinicians found the experience valuable. Recommendations about how to develop a patient-teacher programme in patient safety are provided. CONCLUSIONS: An educational paradigm that includes patients as teachers and collaborative learners with clinicians in patient safety is feasible, valued by clinicians and P/F and promising for P/F-centred medical error disclosure and prevention training.
