RESUMO

BACKGROUND: Communication barriers are a major cause of health disparities for patients with limited English proficiency (LEP). Medical interpreters play an important role in bridging this gap, however the impact of interpreters on outpatient eye center visits has not been studied. We aimed to evaluate the differences in length of eyecare visits between LEP patients self-identifying as requiring a medical interpreter and English speakers at a tertiary, safety-net hospital in the United States. METHODS: A retrospective review of patient encounter metrics collected by our electronic medical record was conducted for all visits between January 1, 2016 and March 13, 2020. Patient demographics, primary language spoken, self-identified need for interpreter and encounter characteristics including new patient status, patient time waiting for providers and time in room were collected. We compared visit times by patient's self-identification of need for an interpreter, with our main outcomes being time spent with ophthalmic technician, time spent with eyecare provider, and time waiting for eyecare provider. Interpreter services at our hospital are typically remote (via phone or video). RESULTS: A total of 87,157 patient encounters were analyzed, of which 26,443 (30.3%) involved LEP patients identifying as requiring an interpreter. After adjusting for patient age at visit, new patient status, physician status (attending or resident), and repeated patient visits, there was no difference in the length of time spent with technician or physician, or time spent waiting for physician, between English speakers and patients identifying as needing an interpreter. Patients who self-identified as requiring an interpreter were more likely to have an after-visit summary printed for them, and were also more likely to keep their appointment once it was made when compared to English speakers. CONCLUSIONS: Encounters with LEP patients who identify as requiring an interpreter were expected to be longer than those who did not indicate need for an interpreter, however we found that there was no difference in the length of time spent with technician or physician. This suggests providers may adjust their communication strategy during encounters with LEP patients identifying as needing an interpreter. Eyecare providers must be aware of this to prevent negative impacts on patient care. Equally important, healthcare systems should consider ways to prevent unreimbursed extra time from being a financial disincentive for seeing patients who request interpreter services.

RESUMO

Purpose: To evaluate attitudes and perceptions toward virtual health (VH) and its usage among eye care providers before, during, and after the coronavirus disease 2019 (COVID-19) pandemic. Materials and Methods: In April and May 2020, an online survey comprised of questions regarding past and current VH practices, as well as plans for future use was distributed among eye care providers nationwide. Results: Of the 117 eye care providers who completed the survey, 96.6% were not using VH before the COVID-19 pandemic. In contrast, 77.4% reported using VH during the pandemic. The majority of visits were for red eye (64.4%, n = 56) and ocular surface complaints (58.6%, n = 51). Examination components tested virtually varied, but most respondents felt these were at least "somewhat reliable." Almost half of respondents (45%) felt it was "very easy" or "somewhat easy" to implement VH and the majority (53.8%, n = 43) were able to get it up and running in under a week. The majority felt the transition to VH was positive (57.5%), however, only 50.4% (n = 53) of those providers planned to use VH regularly once able to see patients safely in clinic again. Conclusions: While the majority of U.S. eye care providers who responded were not using VH before the COVID-19 pandemic, just months into the U.S. outbreak, 77.4% were using VH in their daily practice. In general, providers used these platforms for urgent examinations, adnexal disease, and postoperative care most often. The majority felt the transition was a positive one, however, only half planned to continue regular use of VH once the pandemic ended.

RESUMO

PURPOSE OF REVIEW: To review the current literature on the relationship between cataract extraction and intraocular pressure (IOP). RECENT FINDINGS: Cataract extraction can be an effective IOP lowering treatment for open and closed angle glaucoma as well as ocular hypertension. In comparative trials studying novel micro-invasive glaucoma surgeries in open angle glaucoma, the control group undergoing cataract extraction alone routinely achieved significant reductions in IOP and medication use postoperatively. Data from the Effectiveness in Angle Closure Glaucoma of Lens Extraction (EAGLE) trials have demonstrated that lens extraction is more effective at lowering IOP than peripheral iridotomy in patients with angle closure and should be considered as first line therapy. Additionally, patients in the ocular hypertension treatment study who underwent cataract extraction over the course of follow-up demonstrated significant IOP lowering sustained over 3 years. SUMMARY: Cataract extraction is an effective method to lower IOP in patients with glaucoma. Pressure lowering is more significant in eyes with narrow angles and those with higher baseline IOP levels. In eyes with angle closure, phacoemulsification alone can lower IOP, but when combined with GSL it may be even more effective. Recent large multicenter randomized trials have further elucidated the benefit of standalone cataract extraction to treat mild to moderate primary open angle glaucoma. Prospective and longitudinal studies that systematically investigate the variables that may influence degree and duration of IOP lowering post cataract extraction are lacking.

RESUMO

PURPOSE OF REVIEW: Adherence to chronic use of topical intraocular pressure (IOP) lowering medications is a fundamental barrier to successful, long-term control in patients suffering from glaucoma. This has fueled innovation to create new vehicles for drug administration, new drug formulations with enhanced bioavailability, and minimally invasive glaucoma surgeries (MIGS) with improved risk-benefit profiles to enhance sustained IOP control. The present article is an overview of novel devices in the pipeline. RECENT FINDINGS: Several new devices that promise to deliver sustained drug therapy and reduce dependence on daily patient adherence are currently being vetted through clinical trials. In addition, the pipeline for new MIGS devices that target sustained IOP control continues to grow. SUMMARY: Alternative drug delivery approaches and novel MIGS devices broaden the treatment options for patients with glaucoma. This will allow the clinician to customize treatment by selecting specific approaches based on each patient's individual needs and coexisting ocular pathologies. Additional comprehensive, large-scale, clinical studies will help define the role that these options hold in a constantly evolving treatment paradigm.

RESUMO

BACKGROUND: Neovascular glaucoma (NVG) is a potentially blinding disease associated with ocular ischaemia. Use of an anti-vascular endothelial growth factor agent has been reported as a treatment option for NVG. The purpose of this study was to investigate initial results regarding the treatment of NVG with intravitreal aflibercept. DESIGN: This study employed a prospective, interventional case series study design. PARTICIPANTS: Patients with newly diagnosed stage 1 or 2 neovascular glaucoma were eligible to participate in this study. METHODS: Four patients with newly diagnosed stage 1 or 2 NVG were treated with intravitreal aflibercept at the time of diagnosis, with planned repeat injection at 4 weeks, 8 weeks and then every 8 weeks thereafter up until 52 weeks after study initiation. MAIN OUTCOME MEASURES: Primary outcomes were regression of neovascularization of the iris and angle (NVI, NVA). Secondary outcome measurements included visual acuity and intraocular pressure (IOP). RESULTS: Intravitreal aflibercept resulted in rapid regression of NVI and NVA. IOP was stable or reduced in all patients at the 52-week study visit. CONCLUSIONS: These results suggest that intravitreal aflibercept may be an effective treatment for stage 1 and 2 NVG, resulting in rapid and sustained regression of NVI and NVA as well as control of IOP. Further research is needed to determine the full duration of effect and the optimal dose and timing of administration.

RESUMO

PURPOSE OF REVIEW: To summarize the reports of both transient and sustained elevation in intraocular pressure (IOP) associated with intravitreal injections of antivascular endothelial growth factor (anti-VEGF) agents and to review the possible mechanisms for these findings. RECENT FINDINGS: Transient elevation in IOP is common after intravitreal injection of anti-VEGF agents. Sustained IOP elevation is less commonly seen but can require medical and/or surgical intervention. The mechanism for sustained IOP elevation is not well understood but has been attributed to trabecular meshwork injury from repeated injections, a potential toxic or inflammatory reaction after exposure to the biologic agents and/or vehicle, or mechanical blockade of the trabecular meshwork by protein aggregates or contaminant particles associated with packaging and injection techniques, among other potential causes. SUMMARY: Intravitreal anti-VEGF injections are commonly used to treat neovascular diseases of the eye. Although they have a favorable side-effect profile, their use can be associated with both transient and sustained elevation in IOP. Further research is necessary to determine the cause of these findings.

RESUMO

Orbital invasion by pituitary tumors is rare. To the best of the authors' knowledge, adrenocorticotrophin (ACTH)-secreting pituitary tumors with orbital invasion have not been described in MEDLINE indexed literature. The authors report 2 cases of ACTH-secreting tumors with orbital invasion. One patient had a history of endoscopic transsphenoidal subtotal resection of an ACTH-secreting tumor and presented with recurrence in the orbit. The second patient had a long history of visual loss considered to be secondary to glaucoma. Neuroimaging revealed a destructive mass involving the sella turcica with extension in the right orbit. Debulking of the mass was performed via a transsphenoidal approach, and histopathology revealed an ACTH-secreting adenoma. ACTH-secreting adenoma should be considered in the differential of tumors involving the sella turcica with orbital invasion.

RESUMO

Purpose: To determine the drop volume and total number of dispensed drops using the Nanodropper eyedrop bottle adaptor (Nanodropper, Inc.) compared to drops dispensed from stock bottles to potentially limit ocular toxicity of these eyedrops and prolong bottle use. Patients and Methods: Six topical ocular hypotensive medications (5 solutions, 1 suspension), one steroid (suspension) and two artificial tears emulsions were selected for this study. An analytical balance was used to determine the mass per 10 drops with and without the volume-reducing adaptor and repeated until the bottles were completely emptied. The density of each product was determined using the calculated density. The average drop volume and number of drops per bottle for the nine medications were compared with and without the adaptor with paired t-testing. Results: When all medications were assessed, the drops delivered with the adaptor were 62.1% smaller than eyedrops administered from standard bottles. Compared to stock bottle eyedrops, which had a mean volume of 39.8 ± 2.1 µL, the adaptor resulted in drops with a mean volume of 15.1 ± 1.0 µL, p<0.0001. The adaptor delivered 2.6x the number of drops dispensed from a standard 2.5 mL bottle (184.1 ± 15.1 drops with adaptor and 69.8 ± 4.9 drops from stock bottle, p<0.0001). Conclusion: The Nanodropper eyedrop bottle adaptor can significantly reduce drop volume and increase the overall number of drops dispensed compared with stock eyedrop bottles. Further studies are needed to elucidate the clinical impact of utilizing decreased drop volume with direct comparison to current standards of care.

RESUMO

PRCIS: Glaucoma patients exhibit worse indices of sleep function by both objective and subjective metrics compared with controls. PURPOSE: The purpose of this study is to characterize the sleep parameters and physical activity levels of glaucoma patients compared with controls. PATIENTS AND METHODS: A total of 102 patients with a diagnosis of glaucoma in at least 1 eye and 31 control subjects were enrolled in the study. Participants completed the Pittsburgh Sleep Quality Index (PSQI) during enrollment and then wore wrist actigraphs for 7 consecutive days to characterize circadian rhythm, sleep quality, and physical activity. The primary outcomes of the study were subjective and objective metrics of sleep quality using the PSQI and actigraphy devices, respectively. The secondary outcome was physical activity, measured by the actigraphy device. RESULTS: From the PSQI survey, glaucoma patients had higher (worse) scores compared with controls for sleep latency, sleep duration, and subjective sleep quality, whereas scores for sleep efficiency were lower (better), suggesting more time spent in bed asleep. By actigraphy, time in bed was significantly higher in glaucoma patients as was time awake after sleep onset. Interdaily stability, quantifying the synchronization to the 24-hour light-dark cycle, was lower in glaucoma patients. There were no other significant differences between glaucoma and control patients with regard to rest-activity rhythms or physical activity metrics. In contrast to the survey data, findings from the actigraphy demonstrated that there were no significant associations between the study group and controls regarding sleep efficiency, onset latency, or total sleep time. CONCLUSIONS: In this study, patients with glaucoma demonstrated several subjective and objective differences in sleep function when compared with controls, whereas physical activity metrics were similar.

RESUMO

PURPOSE: To determine differences in cataract surgery outcomes between English proficient (EP) and limited English proficiency (LEP) patients. SETTING: Sue Anschutz-Rodgers Eye Center, Aurora, Colorado. DESIGN: Retrospective. METHODS: Patients who underwent phacoemulsification at the Sue Anschutz-Rogers Eye Center between January 2014 and February 2020 were included. Patients who self-identified as needing or preferring an interpreter in medical encounters were defined as LEP. Differences in surgical characteristics and outcomes including cataract maturity, surgical complexity, and surgical complications were analyzed. RESULTS: 868 eyes (6.4%) were identified from LEP patients. LEP patients were more likely to have mature cataracts (5.1% vs 2.3%, P < .0001). LEP patients' surgeries were more likely to be considered complex (27.8% vs 15.3%, P < .0001) and use higher cumulative dissipated energy (mean of 9.5 [SD = 9.5] vs 7.2 [SD = 7.1], P < .0001). Preoperative visual acuity was worse in LEP patients (logMAR 0.566 [SD = 0.64] vs 0.366 [SD = 0.51], P < .0001) but showed greater improvement after surgery (logMAR 0.366 [SD = 0.54] vs 0.254 [SD = 0.41], P < .0001). There were no significant differences in operative time, intraoperative or postoperative complications. More LEP patients were on steroids 4 weeks postoperatively when compared with EP patients (14.6% vs 10.1%, P < .0002). LEP patients were less likely to undergo subsequent YAG capsulotomy (7.3% vs 12.8%, P < .0001). CONCLUSIONS: Disparities in cataract outcomes between EP and LEP patients was demonstrated. Further research into ophthalmic health disparities for LEP patients is needed to understand the root causes and how they can be addressed.

RESUMO

INTRODUCTION: To compare outcomes of phacoemulsification combined with endoscopic cyclophotocoagulation (phaco/ECP), first generation iStent implantation (phaco/iStent), or both (phaco/iStent/ECP) in patients with open-angle glaucoma. METHODS: A retrospective chart review was performed on patients at the University of Colorado Department of Ophthalmology. Outcomes included intraocular pressure (IOP), medication use, best corrected visual acuity (BCVA), and surgical complications were analyzed. Success was defined as IOP reduction of ≥ 20% and/or reduction by at least one glaucoma medication. RESULTS: A total of 394 eyes were included in the study. There were 170 eyes (43.1%) in the phaco/ECP group, 175 eyes (44.4%) in the phaco/iStent group, and 49 eyes (12.4%) in the phaco/iStent/ECP group. The mean pre-operative IOP was 15.9 mmHg for phaco/ECP, 15.8 mmHg for phaco/iStent, and 15.2 mmHg for phaco/iStent/ECP. At 24 months, the mean IOP was 13.7 mmHg (p < 0.0001), 14.2 mmHg (p = 0.0001), and 13.0 mmHg (p = 0.0007), respectively. The mean pre-operative number of glaucoma medications was 2.0 for phaco/ECP, 1.4 for phaco/iStent, and 2.2 for phaco/iStent/ECP and at 24 months post-surgery decreased to, 1.8 (p = 0.011), 0.9 (p < 0.0001), and 1.7 (p = 0.01), respectively. The success rate at 24 months was 54.4% for phaco/ECP, 75.3% for phaco/iStent, and 55.6% for phaco/iStent/ECP. CONCLUSION: Phacoemulsification when combined with ECP, iStent, or both, lowered IOP and glaucoma medication reliance at 24 months. The success rate for phaco/iStent was significantly higher than phaco/ECP. When iStent was added to phaco/ECP, the success rate was higher at earlier postoperative visits compared to the phaco/ECP alone.

RESUMO

Purpose: To investigate the relationship between limited English proficiency (LEP) and diabetic retinopathy (DR) in patients presenting for cataract surgery. Methods: This is a retrospective observational study of patients who underwent cataract surgery between January 2014 and February 2020. Patients who self-identified as needing or preferring an interpreter were defined as having LEP. Differences in demographics, characteristics, and outcomes including history of type 2 diabetes (T2DM), DR, preoperative best corrected visual acuity (BCVA), macular edema, and anti-vascular endothelial growth factor injections were analyzed. Statistical comparisons were assessed using logistic regression with generalized estimating equations. Results: We included 13,590 eyes. Of these, 868 (6.4%) were from LEP patients. Patients with LEP were more likely to be Hispanic (P < 0.001), female sex (P = 0.008), or older age (P = 0.003) and have worse mean BCVA at presentation (P < 0.001). Patients with LEP had a significantly higher rate of T2DM (P < 0.001), macular edema (P = 0.033), and DR (18.1% vs. 5.8%, P < 0.001). Findings remained significant when controlling for age, sex, race/ethnicity, and type of health insurance. Patients with LEP and DR were more likely to have had later stages of DR (P = 0.023). Conclusions: Patients with LEP presenting for cataract surgery had a higher rate of DR and associated complications compared to patients with English proficiency. Further studies are needed to understand how language disparities influence health and what measures could be taken to improve healthcare in this vulnerable population. Translational Relevance: Our study highlights healthcare disparities within ophthalmology and emphasizes the importance of advocating for improved healthcare delivery for patients with LEP.

RESUMO

OBJECTIVES: To describe the efficacy and safety of goniotomy with trabecular meshwork excision using the Kahook Dual Blade (KDB, New World Medical Inc., Rancho Cucamonga, CA) in patients with severe or refractory glaucoma. METHODS: This retrospective multicentre case series reports on 40 eyes with severe or refractory open-angle glaucoma that underwent standalone or combined KDB goniotomy and were followed for 12 months post-operatively in the United-States, Mexico and Switzerland. Surgical success was defined as an intraocular pressure (IOP) reduction ≥20% from baseline at 12 months, with fewer medications than preoperatively. Mean IOP and antiglaucoma medication reduction, probabilities of achieving an IOP ≤16 or 18 mmHg, and adverse events were also analysed. RESULTS: Mean IOP decreased from 18.1 ± 5.0 mmHg at baseline to 14.8 ± 3.7 mmHg at 12 months (18.2% reduction, P < 0.001). Concomitantly, the mean number of glaucoma medications decreased from 2.5 ± 1.4 to 1.7 ± 1.2 (32% reduction, P = 0.002). The proportion of eyes achieving an IOP reduction of more than 20% from baseline was 37.5% (n = 15) at 12 months. At 12 months, 67.5% and 82.5% achieved a medicated IOP ≤ 16 and ≤18 mmHg, respectively. No severe complications were reported. CONCLUSION: Excisional goniotomy with KDB achieves a statistically significant IOP and antiglaucoma medication reduction in severe or refractory glaucoma over a period of 12 months. While its efficacy decreases with time, its favourable safety profile makes it a potentially useful primary or adjunctive procedure in high-risk eyes.

RESUMO

PURPOSE: To compare bleb survival and histology after implantation of the EX-PRESS™ glaucoma filtration device versus silicone tubes in a rabbit model of filtration surgery. METHODS: Glaucoma filtration surgery was performed on one eye each of twelve New Zealand white rabbits. Eyes were randomized to implantation with the EX-PRESS™ filtration device (n=6) or a silicone tube (n=6). Bleb vascularity was evaluated at three and six weeks using a standard scale. At 6 weeks, eyes were enucleated and a histologic analysis was performed. Bleb survival was also recorded for the two groups. RESULTS: Histologically, a thin capsule consisting of mild fibroblast proliferation associated with intercellular collagen was present around both implants. Both groups demonstrated a mild infiltration of plasma cells and polymorphonuclear leukocytes. Bleb vascularity was similar between both groups at three and six weeks post-operatively. Bleb survival between the two groups was not significantly different. CONCLUSIONS: Similar outcomes were noted after glaucoma filtration surgery using either silicone tubes or the EX-PRESS™ glaucoma filtration device in this rabbit model. Both implants appear to be relatively inert with little difference in biocompatibility and bleb survival.

RESUMO

PURPOSE: To determine the effect of a sustained-release dexamethasone implant (Ozurdex(®)) on wound healing after glaucoma filtration surgery in a rabbit model. METHODS: Twelve new zealand white rabbits were divided into three groups: filtration surgery with intraoperative subconjunctival implantation of Ozurdex(®) (n=6), filtration surgery with intraoperative topical application of mitomycin-C (MMC; n=6), and filtration surgery with intraoperative topical application of balanced salt solution (BSS; n=12). A standard scale was used to grade bleb vascularity at three and six weeks after the initial operation. Bleb survival was also recorded for comparison between the three groups. Histologic analysis was performed with attention to cellularity and collagen deposition. RESULTS: MMC-treated blebs demonstrated decreased numbers of goblet cells compared to all other groups. Blebs treated with Ozurdex(®) maintained a near normal number of goblet cells with modest collagen deposition. The control eyes treated with only BSS had significant collagen deposition and increased cellularity compared to both the Ozurdex(®) and MMC groups. Bleb vascularity was not significantly different among groups at the three and six week post-operative evaluations. MMC-treated and Ozurdex(®)-treated blebs had significantly prolonged bleb survival compared to blebs treated with only BSS. In addition, MMC-treated blebs had significantly longer survival compared to Ozurdex(®)-treated blebs. CONCLUSIONS: The results of this study support the utility of extended-release dexamethasone (Ozurdex(®)) as a wound modulating agent in a rabbit model of filtration surgery. Further animal and human studies are needed to better characterize a possible role for Ozurdex(®) in filtration surgery.

RESUMO

AIM: To compare intraocular pressure (IOP) readings obtained with Perkins tonometry, iCare Home, iCare 200, and Tonopen to IOP readings obtained with the manometer of a perfusion system to assess the accuracy and reproducibility of each method of tonometry at set pressures. METHODS: The IOP of human cadaveric eyes (n=2) was measured using a manometer inserted into the eye through the optic nerve. IOP measurements were obtained using a Perkins tonometer, iCare Home, iCare 200, and Tonopen. These measurements were compared to set point IOP measurements of a manometer to determine accuracy and reproducibility of each device. RESULTS: Mean IOP readings obtained with the Perkins tonometer compared to manometer readings demonstrated a difference of -1.0±5.0 mm Hg (P=0.45), indicating a lower reading on average than manometery although not significant. Mean IOP difference between iCare 200 and manometer was 5.3±2.2 mm Hg (P<0.0001). Mean difference in IOP between iCare Home and manometer was 3.5±2.4 mm Hg (P=0.0004). Mean IOP difference compared to manometer was 4.6±4.0 mm Hg for the Tonopen (P<0.0001). IOP measurements obtained with the Perkins tonometer demonstrated a standard deviation of 5.0 mm Hg while the Tonopen measurements demonstrated a 4.0 mm Hg standard deviation. In comparison, iCare 200 and iCare Home demonstrated 2.2 and 2.4 mm Hg standard deviation, respectively. CONCLUSION: Applanation tonometry produces more accurate IOP readings than rebound tonometry or Tonopen, however it demonstrates greater variability than the other forms of tonometry. Rebound tonometry is more reproducible but tends to over-estimate IOP.

RESUMO

AIM: To assess the relationship between axial length (AL) and intraocular lens (IOL) rotation among eyes receiving a toric IOL and subsequently entered into an online toric back-calculator database. METHODS: Retrospective analysis of data collected online via astigmatismfix.com, a freely available online toric back-calculator where surgeons enter pre- and post-operative information to help manage residual postoperative astigmatism. Included records were deemed valid with entry of AL and IOL orientation between January 2017 and March 2019. Rotation was determined by a difference of ≥5° between pre-operative intended IOL orientation and actual post-operative IOL orientation. Frequency and magnitude of rotation are presented with means and associated standard deviation (SD). Linear regression models of this association are presented. RESULTS: Records of 6752 eyes were included in the analysis, of which 74.8% were determined to have a rotated IOL. The magnitude of rotation increased with each millimeter (mm) increase in AL with a mean rotation of 13.3° (SD: 12.8°) for eyes with AL 20-20.9 mm and a maximum mean rotation of 30.6° (SD: 30.3°) among eyes with AL 29-29.9 mm. General linear modeling demonstrated a significant association (P<0.0001) with a parameter estimate of 1.19 (standard error: 0.159) and R 2 of 0.0083. CONCLUSION: Analysis from an online database indicates that toric IOLs inserted into eyes with longer AL are more likely to rotate and to rotate more degrees from the target axis. The findings from this study are clinically relevant for surgeons implanting toric IOLs.

RESUMO

PURPOSE: To assess whether iCare HOME rebound tonometry can detect therapy-related changes during self-monitoring of intraocular pressure (IOP). DESIGN: Prospective clinical trial. PARTICIPANTS: A total of 43 eyes (n = 27 subjects) with open-angle glaucoma or ocular hypertension were enrolled during standard-of-care clinic visits. Participants were grouped into control eyes managed on stable therapy (n = 18 eyes) or therapy change eyes undergoing selective laser trabeculoplasty (SLT, n = 8 eyes), initiating topical therapy (n = 8 eyes), or adding a second medication to existing monotherapy (n = 9 eyes). METHODS: Subjects recorded IOP 4 times daily for 1 week using iCare HOME tonometry. Upon tonometer return, subjects underwent SLT or new medication start; an additional week of iCare HOME measurements was collected after 4 to 6 weeks. Control subjects recorded an additional week of measurements after 6 weeks. Measurements were grouped into 4 time periods (5-10 am, 10 am to 3 pm, 3-8 pm, 8 pm to 1 am). Goldmann applanation tonometry (GAT) was performed at each study visit for comparison. MAIN OUTCOME MEASURES: Detection of therapy response defined as an IOP reduction of ≥20%. RESULTS: For eyes that demonstrated a therapy response by GAT (n = 11), iCare HOME detected a therapy response in 90.9% of eyes in ≥1 time period and 45.5% of eyes in all 4 time periods. In eyes without a GAT-measured therapy response (n = 14), iCare HOME detected a response for 71.4% (n = 10) of eyes in ≥1 time period and for 7.1% of eyes (n = 1) at all 4 time periods. In treatment eyes, intraday and interday average minimum and maximum IOP, as well as interday IOP range, were significantly reduced after therapy without a significant change in intraday IOP range. Control group eyes did not demonstrate a significant change in average IOP minimum, maximum, or range between study weeks. CONCLUSIONS: Home tonometry with iCare HOME reliably detects therapy-related IOP changes in patients with glaucoma and ocular hypertension. Treatment responses correlated well with in-office GAT and may detect treatment responses missed by GAT. Intraocular pressure measurements via home tonometry provide additional clinical information regarding intraday and interday IOP fluctuation beyond standard of care in office GAT measurements. The iCare HOME is a valuable tool to monitor therapeutic efficacy in patients with glaucoma.

RESUMO

PRCIS: Designed with novel features to facilitate implantation and improve safety, the Ahmed ClearPath (ACP) glaucoma drainage device (GDD) provided intraocular pressure (IOP) reduction comparable with other GDDs in eyes with refractory glaucoma in a multicenter retrospective study. PURPOSE: To present clinical outcomes with a novel valveless GDD (ACP, New World Medical). The 250 and 350 mm2 models feature a contoured plate for optimal globe apposition, anteriorized suture points to facilitate suturing to the globe, and a prethreaded 4-0 polypropylene ripcord suture. METHODS: This was a multicenter retrospective analysis of eyes with medically and/or surgically uncontrolled glaucoma implanted with the 250 or 350 mm2 ACP either as a standalone procedure or in combination with other procedures. Pre-, intra-, and postoperative data through 6 months were collected. RESULTS: A total of 104 eyes (100 subjects) received the ACP by 10 US surgeons, 63.5% of which had primary open-angle glaucoma and 62.5% had severe glaucoma. Mean baseline IOP was 26.3 (9.0) mm Hg and mean medication use was 3.9 (1.3). Through 6 months' follow-up, mean IOP ranged from 13.6 to 16.7 mm Hg and mean medication use from 0.9 to 1.9 medications (P<0.0001 at all timepoints for each outcome measure). At 6 months, mean IOP was 13.7 mm Hg (-13.0 mm Hg, 43.0%, P<0.0001) and mean medication use was 1.9 medications per eye (-2.1, 47.7%, P<0.0001). Common adverse events included anterior chamber inflammation (16.3%), hyphema (15.4%), and hypotony (6.7%). CONCLUSION: The new ACP appears to be safe and efficacious as a standalone procedure or in combination with other procedures for uncontrolled glaucoma, and may be considered as a GDD option for patients in whom its unique design may facilitate the implantation process.

RESUMO

PURPOSE: To determine the prevalence of physician burnout among ophthalmologists in the United States and identify associated risks. SETTING: All practice types within the United States. DESIGN: Cross-sectional study. METHODS: A survey was distributed through email listservs to several national ophthalmology societies. Participants completed a modified Mini Z Burnout Survey, a 10-item questionnaire measured in 5-point Likert scales, followed by demographic questions. The Mini Z Burnout survey assessed 3 main outcomes: stress, burnout, and work satisfaction. The percentage of subgroups experiencing burnout were presented and comparisons made with odds ratios from logistic regression modeling. RESULTS: Of the 592 ophthalmologists responding to the survey, 37.8% (224) self-reported symptoms of burnout with a low of 30.8% (12/39) for vitreoretinal specialists to a high of 45.4% (30/66) for uveitis specialists. Most of those reporting burnout were categorized as mild (65.2% [146/224]), followed by moderate (29.5% [66/224]) and severe (5.4% [12/224]). Women had almost twice the odds of reporting burnout (odds ratio [OR] = 1.9 [95% CI: 1.3-2.7]; P = .0005). Physicians employed in academic (OR = 2.0 [95% CI: 1.2-3.2]; P = 0.007) and hospital facilities (OR = 2.4 [95% CI: 1.3-4.6]; P = .008) reported higher rates of burnout compared with those in large private groups. Burnout was associated with self-reported low work control, insufficient time for documentation, and misalignment with departmental leaders (P < .0001). CONCLUSIONS: Ophthalmologists exhibited a high degree of self-reported burnout in the U.S. This study highlights sex, employment autonomy, and practice type as major factors associated with burnout.
