RESUMO
PURPOSE: To develop a patient-reported outcome measure to assess the impact of glaucoma and treatment, including minimally invasive glaucoma surgery (MIGS). DESIGN: Observational study before and after concomitant cataract and Food and Drug Administration-approved implantable MIGS device surgery. SETTING: Survey administration was on a computer, iPad, or similar device. PATIENT POPULATION: 184 adults completed the baseline survey, 124 a survey 3 months after surgery, and 106 the 1-month test-retest reliability survey. The age range was 37 to 89 (average age = 72). Most were female (57%), non-Hispanic White (81%), and had a college degree (56%). MAIN OUTCOME MEASURES: The Glaucoma Outcomes Survey (GOS) assesses functional limitations (27 items), vision-related symptoms (7 items), psychosocial issues (7 items), and satisfaction with microinvasive glaucoma surgery (1 item). These multiple-item scales were scored on a 0 to 100 range, with a higher score indicating worse health. RESULTS: Internal consistency reliability estimates ranged from 0.75 to 0.93, and 1-month test-retest intraclass correlations ranged from 0.83 to 0.92 for the GOS scales. Product-moment correlations among the scales ranged from 0.56 to 0.60. Improvement in visual acuity in the study eye from baseline to the 3-month follow-up was significantly related to improvements in GOS functional limitations (r = 0.18, P = .0485), vision-related symptoms (r = 0.19, P = .0386), and psychosocial concerns (r = 0.18, P = .0503). Responders to treatment ranged from 17% for vision-related symptoms to 48% for functional limitations. CONCLUSIONS: This study supports using the GOS for ophthalmic procedures such as MIGS. Further evaluation of the GOS in different patient subgroups and clinical settings is needed.
RESUMO
Introduction: This manuscript describes data from an original study, simulating a tele-glaucoma programme in an established clinic practice with an interdisciplinary team. This is a 'real life' trial of a telemedicine approach to see a follow-up patient. The goal is to evaluate the accuracy of such a programme to detect worsening and/or unstable disease. Such a programme is attractive since in-clinic time could be reduced for both the patient and provider. This study evaluates agreement between in-person and remote assessment of glaucoma progression. Methods: A total of 200 adult glaucoma patients were enrolled at a single institution. The in-person assessment by an optometrist or glaucoma specialist at time of enrolment was used as the gold standard for defining progression. Collated clinical data were then reviewed by four masked providers who classified glaucoma as progression or non-progression in each eye by comparing data from enrolment visit to data from the visit immediately prior to enrolment. Agreement of glaucoma progression between the masked observer and the in-person assessment was determined using Kappa statistics. Intra-observer agreement was calculated using Kappa to compare in-person to remote assessment when both assessments were performed by the same provider (n = 279 eyes). Results: A total of 399 eyes in 200 subjects were analysed. Agreement between in-person versus remote assessment for the determination of glaucoma progression was 63%, 62%, 69% and 68% for each reader 14 (kappa values = 0.19, 0.20, 0.35 and 0.33, respectively). For intra-observer agreement, reader 1 agreed with their own in-person assessment for 65% of visits (kappa = 0.18). Discussion: Intra-observer agreement was similar to the agreement for each provider who did not see the patient in person. This similarity suggests that telemedicine may be equally effective at identifying glaucomatous disease progression, regardless of whether the same provider performed both in-clinic and remote assessments. However, fair agreement levels highlight a limitation of using only telemedicine data to determine progression compared with clinical detail available during in-patient assessment.

PURPOSE: Glaucoma specialists and optometrists who work in a team model at a single institution utilize a common definition of glaucoma progression and treatment algorithm. The purpose of this study was to assess the consistency of agreement in identifying glaucoma progression among glaucoma specialists and optometrists of 1 team. METHODS: In total, 399 eyes of 200 patients age 18 or older with glaucoma were enrolled over 2 years. Clinical data, disc photographs, optical coherence tomography (OCT), and visual fields were independently reviewed by 2 masked optometrists and 2 masked fellowship-trained glaucoma specialists. Each eye was judged as progression or no progression of glaucomatous disease. The following were assessed: (1) agreement among optometrists; (2) agreement among glaucoma specialists; and (3) agreement among optometrists and glaucoma specialists. The frequency of use of testing modality to determine progression was also studied. κ statistics were used to evaluate agreements. RESULTS: Optometrists agreed with each other for 74.2% of the eyes assessed (κ=0.42), whereas glaucoma specialists agreed with each other for 78.7% of eyes (κ=0.39). All 4 providers agreed with each other for 54.4% of the eyes evaluated (κ=0.37). Providers had the highest agreement when the progression decision was based on disc hemorrhage (92%) and the lowest agreement when based on OCT progression analysis (36%). Compared with optometrists, glaucoma specialists used OCT (P≤0.01) more frequently to determine disease progression. CONCLUSIONS: Fair to moderate agreement levels were found among providers in their assessment of glaucoma progression, suggesting that a team approach to glaucoma management may be effective. Further work is needed to investigate ways to optimize consistency within the glaucoma team.

PURPOSE: To create a standardized method for evaluating the video recordings of patients self-instilling eye drops and to determine the level of agreement of eye drop instillation efficacy, safety and efficiency ratings by three masked graders. DESIGN: Prospective cross-sectional study. PARTICIPANTS: 78 patients with open-angle glaucoma or ocular hypertension who had at least 6 months of experience with the use of eye drop medications. METHODS: Participants were video recorded while self-instilling artificial tears sequentially to both eyes. Three masked observers graded these video recordings on three criteria: efficacy (the determination of whether an eye drop was instilled on the ocular surface), safety (assessment of whether the tip of the medication bottle made contact with the ocular surface or eyelids), and efficiency (the number of eye drops expressed from the bottle). MAIN OUTCOME MEASURES: After grading the video recordings based on efficacy, safety, and efficiency, kappa statistics were used to estimate inter-rater agreement. RESULTS: The mean kappa level of agreement for efficacy, safety, and efficiency was 0.64 (95% confidence interval (CI), 0.42-0.87), 0.73 (95% CI, 0.58-0.88), and 0.62 (95% CI, 0.42-0.81), respectively. CONCLUSIONS: We demonstrated good inter-rater reproducibility of the masked analysis of video recordings of patients self-instilling eye drops based on three criteria: efficiency, safety, and efficacy.

OBJECTIVE: The aim of this study was to assess the impact of cognition, baseline motor function, and co-morbid medical conditions on functional change, discharge destination, and discharge needs in patients admitted to acute rehabilitation for Parkinson-related impairments. DESIGN: This retrospective chart review study evaluated the records of patients admitted to acute rehabilitation over a 5-yr period with a primary impairment category of parkinsonism. Functional status was measured at admission and discharge; 3-mo follow-up function was also collected in a sample of discharged patients. RESULTS: Eighty-nine patients (mean age, 74.26 yrs) were admitted over the 5-yr time frame. A more complicated Medicare tier diagnosis (tier 2) was associated with lower total and motor score Functional Independence Measure gains compared with tier 3 (P = 0.009 and P = 0.016, respectively). Cognitive scores at admission were not related to need for caregivers upon discharge. Overall Functional Independence Measure gain (adjusted R(2) = 0.073, P = 0.006) and Functional Independence Measure gain efficiency (adjusted R(2) = 0.142, P < 0.001) inversely correlated with age. At the 3-mo follow-up, a random sample (38%) of patients contacted postdischarge demonstrated continued improvements. CONCLUSIONS: Significant improvement may be seen after acute rehabilitation in patients with Parkinson disease, irrespective of cognitive impairment. More complicated medical tier diagnoses result in less Functional Independence Measure gain, and older individuals with Parkinson disease are more likely to show less functional change. However, functional improvements are still statistically significant.

Dysregulation of iron homeostasis is implicated in Alzheimer's disease (AD). In this pilot study, common variants of the apolipoprotein E (APOE) and HFE genes resulting in the iron overload disorder of hereditary hemochromatosis (C282Y, H63D and S65C) were evaluated as factors in sporadic AD in an Ontario sample in which folic acid fortification has been mandatory since 1998. Laboratory studies also were done to search for genetic effects on blood markers of iron status, red cell folates and serum B12. Participants included 58 healthy volunteers (25 males, 33 females) and 54 patients with probable AD (20 males, 34 females). Statistical analyses were interpreted at the 95% confidence level. Contingency table and odds ratio analyses supported the hypothesis that in females of the given age range, E4 significantly predisposed to AD in the presence but not absence of H63D. In males, E4 significantly predisposed to AD in the absence of H63D, and H63D in the absence of E4 appeared protective against AD. Among E4+ AD patients, H63D was associated with significant lowering of red cell folate concentration, possibly as the result of excessive oxidative stress. However, folate levels in the lowest population quartile did not affect the risk of AD. A model is presented to explain the experimental findings.
