Early Experience With Full-scope Shared-care Teleglaucoma in Canada.

PRCIS: Large Canadian full-scope, shared-care teleglaucoma facilitates efficient management and diversion of medically stable patients away from overburdened subspecialty clinics while allowing patients the convenience of shorter travel, shorter wait time, and continuity with one provider. This report shares Care1 protocol, early patient characteristics, and quality data. PURPOSE: This paper describes early experience with Care1, a large full-scope, shared-care teleglaucoma program. Optometrists located in high-demand locations saw patients in-person, acquired clinical history, performed a physical examination, organized diagnostic testing, then uploaded data to a proprietary online platform where they were able to collaborate with participating ophthalmologists to make plans for patient care. MATERIALS AND METHODS: The Care1 database was queried for all patients with a diagnosis of glaucoma or glaucoma suspect seen between February 2016 and March 2017. Clinical characteristics like diagnosis, ocular medication history, best-corrected visual acuity, intraocular pressure, cup-to-disc ratios, optical coherence tomography imaging results, and central corneal thickness were collected. Quality metrics studied included rates of referral to an in-person ophthalmologist and consistency of cup-to-disc assessments between in-person optometrists and remote ophthalmologists. RESULTS: A total of 4070 patients received care at a Care1 teleophthalmology site in 2 provinces for glaucoma assessment from February 2016 to March 2017. The population was 55.1% female, and the average age was 57.8 years. Overall, 97.3% of patients had a best-corrected visual acuity between 20/20 and 20/40 and 3.3% had an intraocular pressure >26. An in-person consultation with an ophthalmologist was recommended for 1.9% of patients. CONCLUSION: Early experience with this full-scope, shared-care teleglaucoma program in Canada indicates it is a convenient, collaborative model of care for glaucoma suspects, and medically stable glaucoma patients.

Telemedicine for Glaucoma: Guidelines and Recommendations.

Background: Glaucoma is the leading cause of irreversible blindness worldwide. Access to glaucoma specialists is challenging and likely to become more difficult as the population ages. Introduction: Using telemedicine for glaucoma (teleglaucoma) has the potential to increase access to glaucoma care by improving efficiency and decreasing the need for long-distance travel for patients. Results: Teleglaucoma programs can be used for screening, diagnostic consultation, and long-term treatment monitoring. Key components of teleglaucoma programs include patient history, equipment, intraocular pressure measurement, pachymetry, anterior chamber imaging/gonioscopy, fundus photography, retinal nerve fiber layer imaging, medical record and imaging software, and skilled personnel. Discussion: Teleglaucoma has tremendous potential to improve patient access to high-quality cost-effective glaucoma care. Conclusions: We have reviewed some special considerations needed to address the complexity of providing guideline-concordant glaucoma care.

Characteristics and predictors of recurrence of anterior and intermediate uveitis in a Canadian referral centre.

OBJECTIVE: To describe the characteristics of uveitis in a Canadian referral centre and to identify predictors of uveitis recurrence. DESIGN: Retrospective cohort study. PARTICIPANTS: Two hundred eighty-five patients with anterior uveitis, intermediate uveitis, or panuveitis. METHODS: We conducted a retrospective study of all patients presenting with anterior uveitis, intermediate uveitis, or panuveitis to the sole uveitis subspecialist at the regional referral centre between September 2004 and March 2006. Patients with posterior uveitis were excluded. Characteristics such as onset, severity, anatomical subtype, systemic association or etiology, recurrence rate, response to treatment, and complications were identified. Regression analysis was used to determine predictors of uveitis recurrence. RESULTS: Three hundred sixty-four eyes from 285 patients were enrolled. Anatomical subtypes were 313 anterior, 36 intermediate, and 15 panuveitis. Systemic associations included ankylosing spondylitis (11.3%), inflammatory bowel disease (6%), sarcoidosis (4.1%), and herpes infections (3.8%). A human leukocyte antigen B27 (HLA-B27)-related association was found in 86 patients (23.6%). Patients with uveitis-associated complications or back symptomatology were more likely to have a recurrence (odds ratios 3.86 and 2.29, respectively). CONCLUSIONS: Common associations were ankylosing spondylitis, inflammatory bowel disease, sarcoidosis, and herpes infections. Patients with uveitis complications and back symptomatology were significantly more likely to have uveitis recurrences.

Discussing resident participation in cataract surgery.

OBJECTIVE: To investigate the proportion of patients who would consent to resident participation in cataract surgery. STUDY DESIGN: Prospective observational case series. PARTICIPANTS: Consecutive series of patients presenting for consideration of cataract surgery. METHODS: A specifically worded discussion of resident participation in cataract surgery was developed on the basis of literature recommendations and was used when obtaining consent for cataract surgery from eligible patients. The main outcome measure was the proportion of patients who consented to resident participation in their cataract surgery. RESULTS: Of the 106 patients eligible for enrollment in the study, 101 (95.3%) consented to resident participation in their cataract surgery. CONCLUSIONS: Despite suggestions in the previous literature to the contrary, surgeons can be reassured that the vast majority of patients, when informed by means of the wording described in this study, will consent to resident participation in their cataract surgery.

Left vertebral artery dissection causing bilateral internuclear ophthalmoplegia.

A 21-year-old woman presented to the emergency department 1 day after a fall. On the day of presentation, she awoke with horizontal diplopia and posterior neck pain. Based on clinical findings, she was diagnosed with bilateral internuclear ophthalmoplegia. A conventional angiogram identified a left vertebral artery dissection. She was started on anticoagulant therapy, with gradual improvement of her diplopia over several months. Diplopia is frequently seen in the emergency department. Internuclear ophthalmoplegia is a cause of binocular diplopia and is important to recognize because it indicates a brainstem lesion requiring neurologic evaluation.

A retrospective cohort study of radial optic neurotomy for severe central retinal vein occlusions.

BACKGROUND: Radial optic neurotomy (RON) is a new surgical procedure that has, until now, been studied only in a case series format. This study was designed to evaluate the efficacy of RON in improving visual acuity in patients suffering from central retinal vein occlusion (CRVO) with visual acuity equal to or worse than 20/100. METHODS: A retrospective cohort study was conducted of consecutive CRVO patients, consisting of 19 who underwent RON and 38 observation subjects matched on presenting visual acuity. RESULTS: The observation group worsened by 0.25 logMAR units from baseline, whereas the surgery group improved by 0.29 logMAR. Multivariate linear regression modelling found that, having controlled for other significant predictors and confounders, the change in visual acuity in the surgery patients was 0.63 logMAR units better than in the observation patients. INTERPRETATION: Our data suggest that RON is a promising treatment for visual acuity loss in severe CRVO causing visual acuity equal to or worse than 20/100. These results should be interpreted cautiously because of the limitations of the study, including the retrospective study design and the use of Snellen visual acuity. Our data suggest that further evaluation of RON is warranted.

Navigator-gated three-dimensional MR angiography of the pulmonary arteries using steady-state free precession.

PURPOSE: To assess the quality of a navigator-gated, free breathing, steady-state free precession (SSFP) technique in comparison to a single breathhold for pulmonary artery imaging in normal volunteers. MATERIALS AND METHODS: Sagittal sections of the left pulmonary arteries of 10 volunteers were obtained with a three-dimensional SSFP sequence using both a single breathhold of 30 seconds and a navigator-gated version of the same sequence. The images were compared and rated by a blinded cardiovascular radiologist for image quality, sharpness, and artifact. RESULTS: On a scale ranging from -2 to 2, in which positive numbers denote that the navigator method was favorable compared to the single breathhold method, image quality was rated 0.7+/-1.4, sharpness 0.6+/-1.5, and artifact 0.1+/-1.4. Thus, there was no statistical difference between the two methods. CONCLUSION: The navigator-gated SSFP sequence is able to acquire images equal in quality to the breathhold sequence. This may be of clinical importance for pulmonary imaging in patients who are unable to sustain a long breathhold.
