Interim Analysis of Clinical Outcomes with Open versus Closed Conjunctival Implantation of the XEN45 Gel Stent.

OBJECTIVE: To examine the longitudinal postoperative outcomes of open versus closed conjunctiva implantation of the XEN45 gel stent. DESIGN: Retrospective multicenter study. SUBJECTS: One hundred ninety-three patients with glaucoma underwent XEN45 implantation via an open or closed conjunctiva approach. METHODS: Data on patient demographics; diagnoses; preoperative and postoperative clinical data; outcome measures, including intraocular pressure (IOP); use of glaucoma medications; visual acuity; and complications were collected. Statistical analyses were performed with P < 0.05 as significant. MAIN OUTCOME MEASURES: Failure was defined as < 20% reduction in IOP from the medicated baseline or a IOP of > 21 mmHg at 2 consecutive visits at postoperative month 1 and beyond, the need for subsequent operative intervention or additional glaucoma surgery, or a catastrophic event, such as loss of light perception. Eyes that had not failed by these criteria and were not on glaucoma medications were considered complete successes. Overall success was defined as those who achieved success either with or without topical medications. RESULTS: Patients were followed for an average of 17 months. Complete success was achieved in 42.5% and 24.7% of the open and closed groups, respectively (P = 0.01). Overall success was achieved in 64.2% and 37.0% of the open and closed groups, respectively (P < 0.001) at the last follow-up. Bleb needling was performed in 12.4% of eyes in the open group compared with 40% of eyes in the closed group. An IOP spike of ≥ 10 mmHg was twice as likely to occur in the closed group compared with the open group during the postoperative period (40% vs. 18%; P = 0.001). CONCLUSIONS: Implantation of XEN45 with opening of the conjunctiva resulted in a lower IOP with greater success and lower needling rate compared with those achieved with the closed conjunctiva technique. Similar rates of postoperative complications and vision loss were noted in each group. Although both procedures provide substantial IOP reduction, the open technique appears to result in higher success rates and fewer postoperative interventions.

Extreme intraocular pressure and steroid-dependent iritis.

A 50-year-old ophthalmic technician was referred by her retina specialist for urgent consultation due to markedly elevated intraocular pressure (IOP) unresponsive to medical therapy. Her history included chronic polyarticular juvenile rheumatoid arthritis and chronic uveitis requiring ongoing topical steroid therapy. She had a sub-Tenon injection of Kenalog (triamcinolone) 18 months prior to referral. Chronic topical anti-inflammatory therapy included nepafenac (Ilevro) and prednisolone acetate 2 times a day. Attempts to discontinue topical steroid resulted in worsening inflammation. The patient was referred when the IOP measured 44 mm Hg in the left eye despite aggressive medical therapy, including acetazolamide. The IOP improved slightly when loteprednol was substituted for prednisolone acetate. Current medications in the left eye include brimonidine 3 times a day, loteprednol 2 times a day, nepafenac 2 times a day, and fixed combination latanoprost + netarsudil at bedtime. Her only medication in the right eye was travoprost. She is intolerant to dorzolamide. She was also taking acetazolamide 500 mg 2 times a day. She was not taking any anticoagulants. Past surgical history included cataract surgery in each eye. She has not had laser trabeculoplasty in either eye. Examination revealed uncorrected visual acuity of J1+ in the right eye (near) and 20/30 in the left eye (mini-monovision). There was no afferent pupillary defect. There was mild band keratopathy in each eye while the central cornea was clear in both eyes without keratic precipitates. Here angles were open to gonioscopy without peripheral anterior synechia. There was mild to moderate flare in each eye with trace cells. The IOP was 17 mm Hg in the right eye and 31 mm Hg in the left. Central corneal thickness measured 560 µm and 559 µm in the right and left eye respectively. There was a well-positioned intraocular lens within each capsule with a patent posterior capsulotomy. There was mild vitreous syneresis but no vitreous cell. The cup to disc ratio was 0.5 in each eye with a symmetrical neural rim. The retina was flat without macular edema. Visual field was normal in both eyes (Figures 1 and 2). Optical coherence tomography of retinal nerve fiber layer (RNFL) is shown in Figure 3 and retinal ganglion cell layer is shown in Supplemental Figure 1 (http://links.lww.com/JRS/A756).JOURNAL/jcrs/04.03/02158034-202301000-00020/figure1/v/2022-12-26T045736Z/r/image-tiffJOURNAL/jcrs/04.03/02158034-202301000-00020/figure2/v/2022-12-26T045736Z/r/image-tiffJOURNAL/jcrs/04.03/02158034-202301000-00020/figure3/v/2022-12-26T045736Z/r/image-tiff Please comment on your management of this patient's left eye.

Casa Colina Fall Risk Assessment Scale-Revised: Predicting Falls in Inpatient Rehabilitation Facilities.

Objective: To revise the Casa Colina Fall risk assessment scale (CCFRAS) using the new Medicare standards required functional ability quality measures and to assess the sensitivity and specificity of this revised fall risk assessment tool. Design: The Casa Colina Fall risk assessment scale-revised (CCFRAS-R) was assessed both retrospectively and prospectively on consecutive patients at 3 inpatient rehabilitation facilities (IRFs) to determine the sensitivity and specificity of this tool in predicting fall risk. Setting: Three IRFs. Participants: A total of 6253 adult patients (N=6253) admitted to 1 of 3 IRF settings including those with stroke, brain injury, spinal cord injury, and other conditions requiring medical rehabilitation, with mean age of 66 years; 50% were female and 50% were male. Interventions: Not applicable. Main Outcomes: Each IRF quantified the number of falls detected for the patient population under evaluation and determined the site-specific sensitivity and specificity of the CCFRAS-R. Results: Quality measures were analyzed for predicting fall risk using logistic regression analyses and found that impaired toileting hygiene, impaired toilet transfer, impaired chair/bed transfer, and difficulty walking 3 meters were the most significant predictors for falls. The area under the curve was used to determine the cut-off score and new scoring for the revised falls scale. A second data set was used to validate the tool showing a sensitivity and specificity of 0.6 and 0.62, respectively (P=.001). The degree of "agreeability" between the original scale and the revised scale was 0.72. Conclusion: This multi-site data set predicted quality measures for the risk of falling resulting in a revised fall risk assessment scale for IRFs. Evaluation of this revised assessment tool indicates that the CCFRAS-R is effective and broadly generalizable for predicting patients at high risk for falling although the sensitivity and specificity of the tool may vary slightly based on environmental differences and patient acuity.

Diagnostic Yield and Complication Rate of Stereotactic Biopsies in Precision Medicine of Gliomas.

Background: An integrated diagnosis consisting of histology and molecular markers is the basis of the current WHO classification system of gliomas. In patients with suspected newly diagnosed or recurrent glioma, stereotactic biopsy is an alternative in cases in which microsurgical resection is deemed to not be safely feasible or indicated. In this retrospective study, we aimed to analyze both the diagnostic yield and the safety of a standardized biopsy technique. Material and Methods: The institutional database was screened for frame-based biopsy procedures (January 2016 until March 2021). Only patients with a suspected diagnosis of glioma based on imaging were included. All tumors were classified according to the current WHO grading system. The clinical parameters, procedural complications, histology, and molecular signature of the tissues obtained were assessed. Results: Between January 2016 and March 2021, 1,214 patients underwent a stereotactic biopsy: 617 (50.8%) for a newly diagnosed lesion and 597 (49.2%) for a suspected recurrence. The median age was 56.9 years (range 5 months-94.4 years). Magnetic resonance imaging (MRI)-guidance was used in 99.3% of cases and additional positron emission tomography (PET)-guidance in 34.3% of cases. In total, stereotactic serial biopsy provided an integrated diagnosis in 96.3% of all procedures. The most frequent diagnoses were isocitrate dehydrogenase (IDH) wildtype glioblastoma (n = 596; 49.2%), oligodendroglioma grade 2 (n = 109; 9%), astrocytoma grade 3 (n = 108; 8.9%), oligodendroglioma grade 3 (n = 76; 6.3%), and astrocytoma grade 2 (n = 66; 5.4%). A detailed determination was successful for IDH 1/2 mutation in 99.4% of cases, for 1p/19q codeletion in 97.4% of cases, for TERT mutation in 98.9% of cases, and for MGMT promoter methylation in 99.1% of cases. Next-generation sequencing was evaluable in 64/67 (95.5%) of cases and DNA methylome analysis in 41/44 (93.2%) of cases. Thirteen (1.1%) cases showed glial tumors that could not be further specified. Seventy-three tumors were different non-glioma entities, e.g., of infectious or inflammatory nature. Seventy-five out of 597 suspected recurrences turned out to be post-therapeutic changes only. The rate of post-procedural complications with clinical symptoms of the Common Terminology Criteria for Adverse Events (CTCAE) grade 3 or higher was 1.2% in overall patients and 2.6% in the subgroup of brainstem biopsies. There was no fatal outcome in the entire series. Conclusion: Image-guided stereotactic serial biopsy enables obtaining reliable histopathological and molecular diagnoses with a very low complication rate even in tumors with critical localization. Thus, in patients not undergoing microsurgical resection, this is a valuable tool for precision medicine of patients with glioma.

Effects of object size and task goals on reaching kinematics in a non-immersive virtual environment.

Object size (large vs. small) and task goal (reach at a comfortable pace vs. reach as fast as possible) are well-accepted task constraints that influence reaching kinematics. However, it is unclear whether these two constraints affect reaching in the virtual environment (VE). The purpose of this study was to examine the effects of these two task constraints in VE. Forty-one healthy adults (11 males; mean age 24.9 years old) participated in this study. All adults were asked to play bubble popping games that ran on our virtual reality (VR) platform (SuperPop VR™), which can precisely measure reaching kinematics (including duration, straightness, jerkiness, and speed) in real time. Participants were blinded to the study purposes, and two task constraints were manipulated: bubble size (small vs. large) and goal (comfortable vs. fast). Participants began with their dominant hand for each condition and alternated hands after each condition was tested three times. A repeated ANOVA was used for analyses. Reaches for small bubbles had longer duration, faster speed, and jerkier with more curved trajectories than reaches for large bubbles; reaches for small bubbles also had larger elbow and shoulder range of motion than reaches for large bubbles. In addition, reaches during participants' comfortable pace had longer duration, slower speed, and larger shoulder range of motion than reaches during their fast pace. Additionally, participants' non-dominant hands had faster speed than their dominant hands. Our findings confirmed that object size and task goals affected reaching kinematics even during VR games. When designing a VR evaluation and intervention program for clinical populations, it is important to consider the virtual object size and task goals as factors in influencing a participant's performance.

Readability and Suitability of Online Patient Education Materials for Glaucoma.

PURPOSE: To assess the quality, content, readability, and accountability of information about glaucoma found online. DESIGN: Cross-sectional study. PARTICIPANTS: Thirteen websites containing patient education materials for glaucoma were analyzed in this study. METHODS: An online Google search was conducted using the keyword "glaucoma." Thirteen medical website results were selected for analysis. Each website was assessed by 3 independent reviewers for suitability, readability, and accountability. The standardized Suitability Assessment of Materials (SAM) tool was used to evaluate the quality and content of information on each website. The Flesch Reading Ease (FRE) score, Flesch-Kincaid Grade Level (FKGL), Coleman-Liau Index (CLI), Simple Measure of Gobbledygook (SMOG) index, Automated Readability Index (ARI), and Linsear Write Formula (LWF) score were used to assess the readability of the websites. The Journal of the American Medical Association (JAMA) accountability benchmarks were used to evaluate each website's accountability. MAIN OUTCOME MEASURES: These included SAM, FRE, FKGL, CLI, SMOG index, ARI, and LWF scores as well as JAMA accountability benchmarks. RESULTS: The average SAM score for all the websites included in this study was 18 points out of a possible 34 points. Eyewiki.org was the lowest-scoring website (11.7 ± 0.6 points), whereas aao.org and nei.nih.gov were the highest-scoring websites (26.0 ± 1.0 points and 26.0 ± 2.6 points, respectively). Three content graders in this study were in moderate agreement (kappa statistic = 0.50). The average FRE score among all the websites was 47.0 (95% confidence interval [CI], 39.3-54.7). The average reading grade score among all the websites was 11.2 (95% CI, 10.0-12.4). Two of the 13 websites (15.4%) satisfied all 4 JAMA accountability criteria. CONCLUSIONS: There is significant variation in the content and quality of freely available, online glaucoma education material. The material is generally either not suitable or only adequate for use. Most websites reviewed are written at a reading grade level higher than that recommended for patient education materials.

The value of stereotactic biopsy of primary and recurrent brain metastases in the era of precision medicine.

Background: Brain metastases (BM) represent the most frequent intracranial tumors with increasing incidence. Many primary tumors are currently treated in protocols that incorporate targeted therapies either upfront or for progressive metastatic disease. Hence, molecular markers are gaining increasing importance in the diagnostic framework of BM. In cases with diagnostic uncertainty, both in newly diagnosed or recurrent BM, stereotactic biopsy serves as an alternative to microsurgical resection particularly whenever resection is not deemed to be safe or feasible. This retrospective study aimed to analyze both diagnostic yield and safety of an image-guided frame based stereotactic biopsy technique (STX). Material and methods: Our institutional neurosurgical data base was searched for any surgical procedure for suspected brain metastases between January 2016 and March 2021. Of these, only patients with STX were included. Clinical parameters, procedural complications, and tissue histology and concomitant molecular signature were assessed. Results: Overall, 467 patients were identified including 234 (50%) with STX. Median age at biopsy was 64 years (range 29 - 87 years). MRI was used for frame-based trajectory planning in every case with additional PET-guidance in 38 cases (16%). In total, serial tumor probes provided a definite diagnosis in 230 procedures (98%). In 4 cases (1.7%), the pathological tissue did not allow a definitive neuropathological diagnosis. 24 cases had to be excluded due to non-metastatic histology, leaving 206 cases for further analyses. 114 patients (49%) exhibited newly diagnosed BM, while 46 patients (20%) displayed progressive BM. Pseudoprogression was seen in 46 patients, a median of 12 months after prior therapy. Pseudoprogression was always confirmed by clinical course. Metastatic tissue was found most frequently from lung cancer (40%), followed by breast cancer (9%), and malignant melanoma (7%). Other entities included gastrointestinal cancer, squamous cell cancer, renal cell carcinoma, and thyroid cancer, respectively. In 9 cases (4%), the tumor origin could not be identified (cancer of unknown primary). Molecular genetic analyses were successful in 137 out of 144 analyzed cases (95%). Additional next-generation sequencing revealed conclusive results in 12/18 (67%) cases. Relevant peri-procedural complications were observed in 5 cases (2.4%), which were all transient. No permanent morbidity or mortality was noted. Conclusion: In patients with BM, frame-based stereotactic biopsy constitutes a safe procedure with a high diagnostic yield. Importantly, this extended to discerning pseudoprogression from tumor relapse after prior therapy. Thus, comprehensive molecular characterization based on minimal-invasive stereotactic biopsies lays the foundation for precision medicine approaches in the treatment of primary and recurrent BM.

Increasing Racial and Ethnic Diversity in Occupational Therapy Education: The Role of Accreditation Council for Occupational Therapy Education (ACOTE®) Standards.

Now more than ever, the lack of racial and ethnic diversity must be addressed within the health care system, specifically in occupational therapy. This change starts with the successful completion of educational programs by underrepresented minority (URM) occupational therapy students. To increase diversity in the profession, accrediting bodies should mandate support for students of all backgrounds to be successful in higher education. As addressed in the American Occupational Therapy Association 2020 Code of Ethics, the Vision 2025 statement and its pillars, current knowledge on health disparities and occupational therapy demographic data, and other health professional programs' accreditation standards, there is a need for an addition to, or revision of, the Accreditation Council for Occupational Therapy Education (ACOTE®) standards to support the recruitment and retention of URM occupational therapy students. What This Article Adds: This column provides an evidence-based rationale to address the need for an ACOTE standard requiring documented efforts to support racial and ethnic diversity within occupational therapy education.

Use of three-dimensional printing as a rehabilitation tool for individuals with deafblindness or vision impairment: a scoping review protocol.

OBJECTIVE: This scoping review aims to synthesize evidence on the practices involving additive manufacturing, also known as three-dimensional printing, as a rehabilitation tool to assist individuals with deafblindness or vision impairment, and to identify which International Classification of Functioning, Disability and Health domains of functioning can be improved by its use. The goal is to inform health care professionals and family caregivers on how additive manufacturing may enhance the quality of life of people with deafblindness or vision impairment. INTRODUCTION: Deafblindness and vision impairment impact many life domains, such as access to information, communication, and mobility. The sense of touch is the main gateway for communication for individuals living with these impairments. Additive manufacturing is a promising technology for producing customized, tactile-based, low-cost tangible objects and devices that could improve the functioning of those with sensory impairment. Emerging studies explore the benefits of additive manufacturing in rehabilitation, education, and inclusion of people living with vision impairment, but very little is known about its use for the deafblind. INCLUSION CRITERIA: This review will consider studies that focus on the most widespread additive manufacturing technologies for the use of individuals living with deafblindness or vision impairment, their family caregivers, or professionals who provide their rehabilitation care. METHODS: A comprehensive search of 10 databases (PsycINFO, MEDLINE, Global Health, PubMed, CINAHL, Embase, ERIC, Web of Science, Engineering Village, and Scopus) will be conducted. Screening of records will be done at the title/abstract level and at the full-text level by independent reviewers of the team.

Open Conjunctival Approach for Sub-Tenon's Xen Gel Stent Placement and Bleb Morphology by Anterior Segment Optical Coherence Tomography.

PRCIS: Sub-Tenon's implantation of the Xen Gel stent resulted in significant intraocular pressure (IOP) lowering along with a low rate of postoperative bleb needling, and a favorable bleb morphology on anterior segment optical coherence tomography (AS-OCT). PURPOSE: The aim was to assess clinical outcomes and bleb morphology following sub-Tenon's implantation of the Xen Gel Stent. METHODS: The medical records of patients who underwent sub-Tenon's Xen Gel Stent implantation with intraoperative mitomycin-C through an open conjunctival approach were reviewed. Postoperative IOP and number of glaucoma medications at 1, 3, 6, 9, and 12 months were assessed. Bleb morphology was analyzed at various timepoints using AS-OCT (Topcon DRI OCT version 1.1.1). RESULTS: Twenty-six eyes were included in the study. Mean age was 69.4±8.0 years. Mean preoperative IOP was 28.1±7.8 mm Hg on an average of 3.5±0.9 glaucoma medications. Mean IOP at postoperative month 12 (n=23 eyes) was 12.9±4.0 mm Hg (P<0.01) on an average of 0.3±0.6 (P<0.01) glaucoma medications. Three eyes (12%) required postoperative needle revision. Bleb morphology in the early postoperative period (≤3 mo) was characterized by multiple small subconjunctival microcysts on AS-OCT. At the intermediate (6 to 12 mo) and long-term (>12 mo) timepoints, reduction in microcysts with multiple internal parallel layers of aqueous flow and a uniform pattern were more frequently noted. All functional blebs were characterized by the presence of a posterior episcleral fluid lake. Failed blebs showed absence of aqueous humor around the distal end of the microshunt. CONCLUSION: Following an open conjunctival approach, sub-Tenon's placement of the Xen Gel Stent with significant IOP lowering was achieved. In eyes with good shunt function, bleb morphology by AS-OCT showed a posterior episcleral fluid lake similar to findings following trabeculectomy.

Immune checkpoint inhibitor associated ocular hypertension (from presumed trabeculitis).

PURPOSE: Immune checkpoint inhibitors (ICIs) are associated with a range of immune-related adverse ophthalmic events. To date, there are scant reports of ocular hypertension coupled with ICI-associated uveitis. However, in instances of ocular hypertension in the context of only mild uveitic reaction and absence of synechiae, trabeculitis is considered. This series describes our observations of presumed trabeculitis in the setting of ICI therapy and investigates the clinical findings, treatment and outcome of these patients. OBSERVATIONS: Two eyes of 2 patients (both male aged 65 and 43) developed a mild anterior uveitis and elevated intraocular pressure (IOP) with open angles and no evidence of peripheral anterior synechiae in association with ICI treatment for their malignancy; and were considered to have presumed unilateral trabeculitis. The patients underwent 10 cycles (6.53 months) and 2 cycles (3.33 months) respectively of ICI therapy before developing ophthalmic symptoms. Neither patient was on systemic or topical steroid treatment at time of diagnosis and there was no suspicion of a viral etiology for the inflammation. Following management, the anterior uveitis resolved and IOP rapidly returned to normal in both eyes: ICI therapy was discontinued in both patients (and uneventfully re-challenged at a lower dose in one patient) and both eyes were treated with a combination of topical and/or oral glaucoma medications and topical steroids. CONCLUSIONS AND IMPORTANCE: Uveitic ocular hypertension has been described with ICI. However, another immune-related mechanism for ocular hypertension with unique clinical characteristics, includes trabeculitis. We describe two cases of trabeculitis in the setting of ICI-therapy. The intraocular inflammation and elevated intraocular pressure which characterizes trabeculitis often responds rapidly to conservative treatment. In both patients checkpoint inhibitor therapy was discontinued and, in one patient, was re-challenged at a lower dose without recurrence. Immunotherapy is now more widely used for cancer treatment and its potential ocular manifestations should be shared with the ophthalmic community.

Comparison of Clinical Outcomes with Open Versus Closed Conjunctiva Implantation of the XEN45 Gel Stent.

PURPOSE: To describe the efficacy and safety of open versus closed conjunctival implantation of the XEN45 Gel Stent (Allergan Inc). DESIGN: Retrospective, multicenter study. PARTICIPANTS: A total of 137 patients with glaucoma who underwent XEN45 implantation via open or closed conjunctival methods. The XEN45 was implanted as a stand-alone procedure or at the time of cataract surgery by 5 surgeons. METHODS: Patient demographics, diagnoses, preoperative and postoperative clinical data, outcome measures including intraocular pressure (IOP), use of glaucoma medications, visual acuity, and complications were collected. Statistical analyses were performed with P < 0.05 as significant. MAIN OUTCOME MEASURES: Failure was defined as less than 20% reduction of IOP from medicated baseline or IOP >21 mmHg at 2 consecutive visits at postoperative month 1 and beyond, the need for subsequent operative intervention or additional glaucoma surgery, or a catastrophic event such as loss of light perception. Eyes that had not failed by these criteria and were not on glaucoma medications were considered complete successes. Eyes that had not failed but required glaucoma medications were defined as qualified successes. RESULTS: Complete success was achieved in 31% and 56% of the closed and open groups, respectively (P = 0.01). Qualified success was achieved in 53% and 71% of the closed and open groups, respectively (P = 0.06). At postoperative month 12, the open conjunctiva group was using fewer glaucoma medications than the closed group (0.9 vs. 1.8, respectively; P = 0.02). At postoperative month 12, the open group had a significantly greater percentage of IOP reduction compared with the closed group (43.1% vs. 24.8%, respectively; P = 0.02). Postoperative needling rates were higher in the closed group compared with the open group (36.1% vs. 11.8%, P = 0.001). CONCLUSIONS: Implantation of the XEN45 with opening of the conjunctiva is a safe and efficacious procedure to lower IOP with comparable success rate and lower needling rate compared with the closed conjunctiva technique. Prospective evaluation of the various methods for XEN45 implantation will allow for further comparison.

Subconjunctival microinvasive glaucoma surgeries: an update on the Xen gel stent and the PreserFlo MicroShunt.

PURPOSE OF REVIEW: This review will provide an update on surgical techniques, outcomes, and complications for two new translimbal bleb-forming surgical glaucoma devices. RECENT FINDINGS: The XEN Gel Microstent and PreserFlo MicroShunt comprise a category of subconjunctival microinvasive glaucoma surgery developed with the aim of improving the predictability and safety profile of bleb-forming procedures. Both devices are made of noninflammatory material which limits postsurgical inflammation and scarring and have a valve-less intrinsic flow-limiting design, which decreases the risk of hypotony. There are various techniques of implantation for the XEN Gel Microstent each with their own advantages and disadvantages. SUMMARY: These devices have demonstrated promising outcomes in early experimental literature with similar intraocular pressure-lowering effects to traditional incisional surgery such as trabeculectomy or tube shunt surgery, but with fewer risks. Future randomized, prospective studies should be done to compare these gel stents and microshunts both to each other and to other traditional glaucoma surgeries.

Acute Solar Retinopathy Imaged With Adaptive Optics, Optical Coherence Tomography Angiography, and En Face Optical Coherence Tomography.

IMPORTANCE: Solar retinopathy is a rare form of retinal injury that occurs after direct sungazing. OBJECTIVE: To enhance understanding of the structural changes that occur in solar retinopathy by obtaining high-resolution in vivo en face images. DESIGN, SETTING, AND PARTICIPANT: Case report of a young adult woman who presented to the New York Eye and Ear Infirmary with symptoms of acute solar retinopathy after viewing the solar eclipse on August 21, 2017. MAIN OUTCOMES AND MEASURES: Results of comprehensive ophthalmic examination and images obtained by fundus photography, microperimetry, spectral-domain optical coherence tomography (OCT), adaptive optics scanning light ophthalmoscopy, OCT angiography, and en face OCT. RESULTS: The patient was examined after viewing the solar eclipse. Visual acuity was 20/20 OD and 20/25 OS. The patient was left-eye dominant. Spectral-domain OCT images were consistent with mild and severe acute solar retinopathy in the right and left eye, respectively. Microperimetry was normal in the right eye but showed paracentral decreased retinal sensitivity in the left eye with a central absolute scotoma. Adaptive optics images of the right eye showed a small region of nonwaveguiding photoreceptors, while images of the left eye showed a large area of abnormal and nonwaveguiding photoreceptors. Optical coherence tomography angiography images were normal in both eyes. En face OCT images of the right eye showed a small circular hyperreflective area, with central hyporeflectivity in the outer retina of the right eye. The left eye showed a hyperreflective lesion that intensified in area from inner to middle retina and became mostly hyporeflective in the outer retina. The shape of the lesion on adaptive optics and en face OCT images of the left eye corresponded to the shape of the scotoma drawn by the patient on Amsler grid. CONCLUSIONS AND RELEVANCE: Acute solar retinopathy can present with foveal cone photoreceptor mosaic disturbances on adaptive optics scanning light ophthalmoscopy imaging. Corresponding reflectivity changes can be seen on en face OCT, especially in the middle and outer retina. Young adults may be especially vulnerable and need to be better informed of the risks of viewing the sun with inadequate protective eyewear.

Subluxated cataract lens surgery using sutured segments or rings and implantation of toric intraocular lenses.

PURPOSE: To evaluate the intraoperative performance and postoperative outcomes of toric intraocular lens (IOL) with suture ring implantation in adult patients with subluxated lenses. SETTING: Department of Ophthalmology, Kaiser Permanente, Santa Clara, California, and the Eye Institute of Utah, Salt Lake City, Utah, USA. DESIGN: Retrospective case review. METHODS: Eyes with subluxated cataractous lenses and preoperative corneal astigmatism having toric IOL implantation with a sutured ring or segment were studied. Preoperative and postoperative analyses included uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and cylindrical power postoperatively and 3, 6, and 12 months postoperatively. RESULTS: Twenty-one eyes of 15 patients were studied. The median follow-up was 14.6 months. The mean CDVA at the final follow-up (0.10 logMAR ± 0.15 [SD]) was significantly improved from the mean preoperative CDVA (0.73 ± 0.40 logMAR). Postoperative cylindrical power was significantly improved in all patients (mean reduction in astigmatism 2.37 ± 1.46 diopters). Patients who required postoperative enhancement had anterior laser capsulotomy for bilateral capsule phimosis (2 eyes), photorefractive keratectomy (1 eye), pupilloplasty (1 eye), and posterior laser capsulotomy (2 eyes). CONCLUSION: Cataract removal and implantation of a toric IOL combined with a sutured ring or segment capsule stabilizing device was a safe and efficacious long-term solution for patients with subluxated cataract lenses and corneal astigmatism.

More standing and just as productive: Effects of a sit-stand desk intervention on call center workers' sitting, standing, and productivity at work in the Opt to Stand pilot study.

This study evaluated the effects of sit-stand desks on workers' objectively and subjectively assessed sitting, physical activity, and productivity. This quasi-experimental study involved one intervention group (n = 16) and one comparison group (n = 15). Participants were call center employees from two job-matched teams at a large telecommunications company in Sydney, Australia (45% female, 33 ± 11 years old). Intervention participants received a sit-stand desk, brief training, and daily e-mail reminders to stand up more frequently for the first 2 weeks post-installation. Control participants carried out their usual work duties at seated desks. Primary outcomes were workday sitting and physical activity assessed using ActivPAL or ActiGraph devices and self-report questionnaires. Productivity outcomes were company-specific objective metrics (e.g., hold time, talking time, absenteeism) and subjective measures. Measurements were taken at baseline, 1, 4, and 19 weeks post-installation. Intervention participants increased standing time after 1 week (+ 73 min/workday (95% CI: 22, 123)) and 4 weeks (+ 96 min/workday (95% CI: 41, 150)) post-intervention, while control group showed no changes. Between-group differences in standing time at one and 4 weeks were + 78 (95% CI: 9, 147) and + 95 min/workday (95% CI: 15, 174), respectively. Sitting time in the intervention group changed by - 64 (95% CI: - 125, - 2), - 76 (95% CI: - 142, - 11), and - 100 min/workday (95% CI: - 172, - 29) at 1, 4, and 19 weeks post-installation, respectively, while the control group showed no changes. No changes were observed in productivity outcomes from baseline to follow-up in either group. Sit-stand desks can increase standing time at work in call center workers without reducing productivity.

Effectiveness of Glaucoma Counseling on Rates of Follow-up and Glaucoma Knowledge in a South Indian Population.

PURPOSE: To evaluate the impact of traditional counseling and patient-centered counseling, either alone or with recorded audio counseling reinforcement, on glaucoma knowledge and clinical follow-up. DESIGN: Prospective randomized controlled trial. METHODS: Newly diagnosed adult glaucoma patients were randomized to 1 of 3 categories of glaucoma counseling: traditional counseling, patient-centered counseling, or patient-centered counseling with audio counseling reinforcement. Demographic and clinical information from each subject was ascertained, and all subjects completed the Glaucoma Knowledge Assessment before and after counseling sessions at the time of diagnosis and at 1-month follow-up. Patients were instructed to return to clinic for routine follow-up at 1, 3, 6, 9, and 12 months after enrollment. A multivariate logistic regression model was used to determine factors associated with appropriate clinical follow-up. RESULTS: Overall, only 13.5% of subjects had appropriate clinical follow-up at 1 year, defined as attending at least 3 follow-up visits during that interval, and there was no significant difference between counseling groups. The mean glaucoma knowledge assessment score (GKAS) improved by 77.6% with the initial counseling intervention (P < .0001), decreased by 17.4% within a 1-month period following initial counseling, and improved by 22.8% (P < .001) after the second counseling intervention. Monthly household income over 2500 rupees, GKAS greater than 5 after initial counseling, and undergoing any ocular surgical procedure were all independent predictors of appropriate follow-up. CONCLUSION: While all 3 counseling methods resulted in transient improvement of patient knowledge regarding glaucomatous disease, follow-up rates were poor for all groups. Poor retention of glaucoma knowledge may impact the likelihood of patient follow-up, and reinforcement with repeated counseling may be beneficial with regard to both disease knowledge and follow-up.

A Widening Gap? Changes in Multiple Lifestyle Risk Behaviours by Socioeconomic Status in New South Wales, Australia, 2002-2012.

BACKGROUND: Socioeconomic inequalities in health outcomes have increased over the past few decades in some countries. However, the trends in inequalities related to multiple health risk behaviours have been infrequently reported. In this study, we examined the trends in individual health risk behaviours and a summary lifestyle risk index in New South Wales, Australia, and whether the absolute and relative inequalities in risk behaviours by socioeconomic positions have changed over time. METHODS: Using data from the annual New South Wales Adult Population Health Survey during the period of 2002-2012, we examined four individual risk behaviours (smoking, higher than recommended alcohol consumption, insufficient fruit and vegetable intake, and insufficient physical activity) and a combined lifestyle risk indicator. Socioeconomic inequalities were assessed based on educational attainment and postal area-level index of relative socio-economic disadvantage (IRSD), and were presented as prevalence difference for absolute inequalities and prevalence ratio for relative inequalities. Trend tests and survey logistic regression models examined whether the degree of absolute and relative inequalities between the most and least disadvantaged subgroups have changed over time. RESULTS: The prevalence of all individual risk behaviours and the summary lifestyle risk indicator declined from 2002 to 2012. Particularly, the prevalence of physical inactivity and smoking decreased from 52.6% and 22% in 2002 to 43.8% and 17.1% in 2012 (p for trend<0.001). However, a significant trend was observed for increasing absolute and relative inequalities in smoking, insufficient fruit and vegetable consumption, and the summary lifestyle risk indicator. CONCLUSIONS: The overall improvement in health behaviours in New South Wales, Australia, co-occurred with a widening socioeconomic gap. IMPLICATIONS: Governments should address health inequalities through risk factor surveillance and combined strategies of population-wide and targeted interventions.
