Smartphone capture of flexible laryngoscopy: Optics, subsite visualization, and patient satisfaction
摘要： Objective: To determine whether a smartphone adaptor can record laryngoscopic videos of adequate quality for clinical diagnosis and communication among otolaryngologists and assess the impact of recorded exams on patient satisfaction. Methods: Twenty adult inpatients undergoing flexible laryngoscopy in a tertiary care medical center were prospectively enrolled. Each subject's larynx was visualized with the standard laryngoscope eyepiece and with an attached mobile phone adaptor with video recording capabilities. A 5-point Likert scale was used by the resident performing the scope to grade the adaptor and eyepiece exams. The same scale was used by an offsite otolaryngology attending to grade the adaptor video. Patients were shown the video, and a satisfaction survey was administered. Results: In all patients, the adaptor was easy to use and required minimal setup. Ninety percent of patients reported an increase in satisfaction after watching the video of their exam. The eyepiece was superior to the adaptor in resolution, focus, color fidelity, brightness, and optical fluidity (P < 0.05). The video recording was deemed sufficient for clinical assessment in 90% of cases. The offsite reviewer determined that there would be 'little' (15%) or 'no value' (65%) in repeating the scope exam in the majority of patients. The laryngeal subsites were equally visible with the eyepiece and the adaptor ('full view,' 85%–100%). Conclusion: Laryngoscopy videos recorded by a portable smartphone adaptor are sufficient for clinical evaluation in the majority of cases. This technology may improve patient satisfaction and communication among clinicians.

Assessment of diabetic teleretinal imaging program at the Portland Department of Veterans Affairs Medical Center
摘要： We conducted a retrospective chart review of 200 diabetic patients who had teleretinal imaging performed between January 1, 2010, and January 1, 2011, at Portland Department of Veterans Affairs (VA) Medical Center outpatient clinics to assess the effectiveness of the diabetic teleretinal imaging program. Twenty patients (10%) had diabetic retinopathy. Ninety percent of the available teleretinal imaging studies were of adequate quality for interpretation. In accordance with local VA policy at that time, all teleretinal imaging patients should have been referred for a dilated retinal examination the following year. Image readers referred 97.5% of the patients to eye clinics for subsequent eye examinations, but the imagers scheduled appointments for only 80% of these patients. The redundancy rate, i.e., patients who had an eye examination within the past 6 mo, was 11%; the duplicate recall rate, i.e., patients who had a second teleretinal imaging performed within 1 yr of the eye examination, was 37%. Rates of timely diabetic eye examinations at clinics with teleretinal imaging programs, particularly when teleretinal imaging and eye clinics were colocated at the same community-based outpatient clinic, were higher than at those without a teleretinal imaging program. We concluded that the Portland VA Medical Center's teleretinal imaging program was successful in increasing the screening rate for diabetic retinopathy.

Use of Telehealth Screening to Detect Diabetic Retinopathy and Other Ocular Findings in Primary Care Settings
摘要： Purpose: To determine the incidence of diabetic retinopathy (DR) and other ocular findings in previously diagnosed diabetes using telehealth retinal screening with nonmydriatic fundus photography (nFP) in primary care physicians’ offices. Methods: A retrospective study based on electronic chart review was performed. All diabetic patients who participated in the Wills Eye Hospital (WEH) telehealth retinal screening program from July 1, 2012 to February 20, 2017 were included. In addition to evaluation of DR, other eye pathologies of the retina were detected using nFP. Results: Overall, 9,946 diabetics participated in the WEH telehealth screening system. After exclusion of missing or unreadable images, 15,180 eyes of 7,624 (76.7%) patients were eligible for final analysis. A total of 1,269 (16.6%) patients were noted to have DR changes in at least one eye. Of those, 475 (37.4%) had mild nonproliferative DR (NPDR) in the more severely affected eye, 712 (56.1%) had moderate NPDR, 33 (2.6%) had severe NPDR, 19 (1.5%) had proliferative DR, and 30 (2.4%) have received pan-retinal photocoagulation previously. In addition, there was evidence of diabetic macular edema detectable on nFP in 34 eyes of 29 patients. Other ocular findings included hypertensive retinopathy (709, 9.3%), increased or asymmetric cup-to-disc ratio (562, 7.4%), age-related cataract (379, 5.0%), cotton-wool spots (221, 2.9%), choroidal nevus (74, 1.0%), age-related macular degeneration (AMD) (66, 0.9%), and epiretinal membrane (48, 0.6%). Patients with hypertensive retinopathy, glaucomatous findings, cataract, or AMD were significantly older (p < 0.001) than those without these ocular pathologies. Conclusion: The WEH Telehealth Screening Program identified DR in approximately one out of six patients and other ocular pathologies in over 25% of the diabetic population that received screenings in Philadelphia area primary care offices. Given the importance of early detection and routine eye care to prevent vision loss for DR patients, these findings have a significant impact.

Nonmydriatic Fundus Photography in Patients with Acute Vision Loss
摘要： Background: Acute visual loss is a common chief complaint in emergency department (ED) patients, but the scarcity of ophthalmologists in most EDs limits its evaluation. Introduction: Our objective was to evaluate whether non-mydriatic fundus photography (NMFP) in the ED helps triage patients with acute visual loss. Materials and Methods: We included 213 patients with acute visual loss evaluated in the ED with NMFP as part of the Fundus Photography versus Ophthalmoscopy Trial Outcomes in the ED studies. Demographics, referral patterns, results of NMFP, and final diagnoses were recorded. Results: A final ophthalmological diagnosis was made in 109/213 (51%) patients. NMFP allowed a definite diagnosis in 51/109 (47%) patients: 14 nonglaucomatous optic neuropathies, 10 papilledema, 13 acute retinal ischemia, 2 retinal detachments, 2 choroidal metastases, 4 maculopathies, and 6 glaucoma. In 58/109 (53%) patients, NMFP was not diagnostic even when interpreted remotely by ophthalmologists due to disorders undiagnosable with NMFP. Ophthalmology consultation was requested in 109/213 (51%) patients, 41/54 (76%) patients with abnormal NMFP versus 68/159 (43%) patients with normal NMPF (p < 0.001). Discussion: Although NMFP allowed rapid diagnosis in 51/213 (24%) patients presenting to the ED with acute visual loss, NMFP alone was not sufficient to detect all ocular diseases; ophthalmology consultation was more often requested when NMFP was abnormal. Conclusions: Our study emphasizes the limitations of tele-ophthalmology with NMFP in remotely detecting ocular diseases related to acute visual loss in the ED. NMFP helped triage and referral decisions and can be used to complement ophthalmology consultations in the ED.
