Severe ocular Mpox in person living with advanced HIV treated with extended course of tecovirimat.

BACKGROUND: People living with HIV are disproportionately represented among people with severe mpox. Mild and self-limiting conjunctival involvement has been well-documented, and severe ocular complications, including keratitis, corneal scarring, and the associated loss of vision, are increasingly recognized. Tecovirimat is the first-line antiviral therapy for severe mpox, but data around the efficacy of systemic antiviral agents for mpox are limited, particularly in cases of ocular mpox. CASE REPORT: Here, we describe a case of sight-threatening necrotic blepharokeratoconjunctivitis in a person with advanced HIV, requiring an extended course of tecovirimat due to persistent mpox viral shedding for nearly 5 months.

System usability, user satisfaction and long-term adherence to mobile hyperacuity home monitoring-prospective follow-up study.

PURPOSE: To evaluate the usability and long-term adherence to the mobile hyperacuity app Alleye in patients with retinal pathology. METHODS: We enroled 72 patients (95 eyes) mainly treated for wet AMD (48/95; 50.5%). We calculated changes of clinical characteristics and the System Usability Score (SUS), and personal ratings of usefulness and number of tests performed per month at a follow-up visit of eighteen months. RESULTS: At baseline, mean best corrected visual acuity (BCVA) was 74.9 letters (SD 14.8), mean age was 69.9 (SD 11.4) and 39/72 (54.2%) were female. Of included patients, 47/72 (65.2%) reported to use mobile devices daily. The retention rate until last follow-up was 73.6 % (53/72). The median SUS score at baseline was 90 (interquartile range (IQR) 82.5-95) and 92.5 (IQR 82.5-95) in the follow-up. No association between changes of SUS and clinical characteristics was seen. At baseline, 76.4% (55/72) stated that they would recommend the app to a friend, 83.3% (60/72) were very satisfied with the app and 58/72 (80.6%) of respondents said they trusted the app. These assessments remained similar among patients remaining on the program until the follow-up. Patients who dropped out of the study (n = 19) did not differ in age, gender, BCVA, and SUS at baseline, but stated that they did not use the mobile device daily (Odds Ratio 7.40 (95%CI: 2.32-23.65); p = 0.001). CONCLUSIONS: The majority of users willing to perform home monitoring with the Alleye app are satisfied with the usability and have a positive attitude towards its trustworthiness and usefulness.

Outcomes on the Utilization of Lipodermoid Skin for Anterior Lamella Reconstruction in Severe Lipodermoids With Eyelid Coloboma: A Case Series.

Two young children with upper lid colobomas and associated lipodermoids underwent eyelid reconstruction using lipodermoid skin as an autograft with good cosmesis. We describe their presentation, surgical management, and clinical progress following reconstruction, demonstrating the suitability of this skin as an adequate graft avoiding the need for further skin graft harvesting in such cases.

Visual outcomes and treatment adherence of patients with macular pathology using a mobile hyperacuity home-monitoring app: a matched-pair analysis.

OBJECTIVE: We compared patients with neovascular age-related macular degeneration (nvAMD), diabetic macular oedema (DMO) and other macular pathologies testing their vision with the hyperacuity home-monitoring app Alleye to patients not performing home-monitoring regarding clinical outcomes and clinical management. DESIGN: Matched-pair analysis. SETTING: Retina Referral Centre, Switzerland. PARTICIPANTS: For each eye using Alleye, we matched 2-4 controls not using home-monitoring based on age, gender, number of previous intravitreal injections (IVI), best corrected visual acuity (BCVA) (Early Treatment Diabetic Retinopathy Study letters), central macular thickness (CRT) and time point of enrolment, using the Mahalanobis distance matching algorithm. We included 514 eyes (288 patients); 107 eyes with nvAMD using home monitoring and 218 controls not using home monitoring, 25 eyes with DMO (n=52 controls) and 40 eyes with miscellaneous conditions (n=72 controls). 173 eyes (33.7%) received no IVI during follow-up. MAIN OUTCOME MEASURES: Improvement of ≥5 letters, number of injection visits and treatment retention after correcting for differences in baseline characteristics with multivariate analyses. RESULTS: The mean follow-up duration was 809 days (range 147-1353) and the mean number of IVI/year among treated eyes was 6.7 (SD 3.1). Mean age at baseline was 70.4 years (SD 10.9), BCVA was 77.6 letters (SD 11.6) and CRT was 263.6 µm (SD 86.7) and was similar between patients using and not using home monitoring. In multivariate analyses, patients using home monitoring had a higher chance to improve visual acuity by ≥5 letters (OR 1.67 (95% CI 1.01 to 2.76; p=0.044)) than controls. Treated eyes using home monitoring had less injection visits/year (-0.99 (95% CI -1.59 to -0.40; p=0.001)) and a longer treatment retention +69.2 days (95% CI 2.4 to 136.0; p=0.042). These effects were similar across retinal pathologies. CONCLUSIONS: This data suggest that patients capable of performing mobile hyperacuity home monitoring benefit in terms of visual acuity and discontinue treatment less often than patients not using home monitoring.

Smartphone-based remote monitoring of vision in macular disease enables early detection of worsening pathology and need for intravitreal therapy.

BACKGROUND/AIMS: To assess the outcomes of home monitoring of distortion caused by macular diseases using a smartphone-based application (app), and to examine them with hospital-based assessments of visual acuity (VA), optical coherence tomography-derived central macular thickness (CMT) and the requirement of intravitreal injection therapy. DESIGN: Observational study with retrospective analysis of data. METHODS: Participants were trained in the correct use of the app (Alleye, Oculocare, Zurich, Switzerland) in person or by using video and telephone consultations. Automated threshold-based alerts were communicated based on a traffic light system. A 'threshold alarm' was defined as three consecutive 'red' scores, and turned into a 'persistent alarm' if present for greater than a 7-day period. Changes of VA and CMT, and the requirement for intravitreal therapy after an alarm were examined. RESULTS: 245 patients performing a total of 11 592 tests (mean 46.9 tests per user) were included and 85 eyes (164 alarms) examined. Mean drop in VA from baseline was -4.23 letters (95% CI: -6.24 to -2.22; p<0.001) and mean increase in CMT was 29.5 µm (95% CI: -0.08 to 59.13; p=0.051). Sixty-six eyes (78.5%) producing alarms either had a drop in VA, increase in CMT or both and 60.0% received an injection. Eyes with persistent alarms had a greater loss of VA, -4.79 letters (95% CI: -6.73 to -2.85; p<0.001) or greater increase in CMT, +87.8 µm (95% CI: 5.2 to 170.4; p=0.038). CONCLUSION: Smartphone-based self-tests for macular disease may serve as reliable indicators for the worsening of pathology and the need for treatment.

False alarms and the positive predictive value of smartphone-based hyperacuity home monitoring for the progression of macular disease: a prospective cohort study.

BACKGROUND: Home monitoring of hyperacuity allows early detection of progression in exudative neovascular age-related macular degeneration (nvAMD) and diabetic macular oedema (DMO). However, false alarms may pose a significant burden to both patients and healthcare professionals alike. PURPOSE: To assess the false alarm rate and positive predictive value of smartphone-based home monitoring of nvAMD and DMO. METHODS: Patients treated with anti-angiogenic therapy in a pro re nata scheme for nvAMD or DMO at the Medical Retina service (Lucerne, Switzerland) between March and June 2016 were included in this prospective cohort study. The home monitoring test Alleye (Oculocare Ltd, Switzerland) provided a session score from 0-100 in addition to a traffic-light system feedback via the smartphone application. Three consecutive "red" scores were considered as a positive test or alarm signal. Specificity, 1-specificity (false alarm rate) and the predictive value for optical coherence tomography-based disease progression were analysed. RESULTS: 73 eyes of 56 patients performed 2258 tests in 222 "follow-up periods". Progression was observed in 141 periods (63.5%). The specificity of the test was 93.8% (95% CI: 86.2-98.0%), the false alarm rate 6.1% (95% CI: 2.0-13.8%), and the positive predictive value 80.0% (95% CI: 59.3-93.2%) for the detection of progression. CONCLUSION: False alarm rates for the detection of progression in macular disease via home monitoring is low. These findings suggest that home monitoring may be a useful adjunct for remote management of nvAMD and DMO.
