[Ti] Título:A proposed minimum data set for international primary care optometry: a modified Delphi study.

[Ab] Resumo:PURPOSE: To identify a minimum list of metrics of international relevance to public health, research and service development which can be extracted from practice management systems and electronic patient records in primary optometric practice. METHODS: A two stage modified Delphi technique was used. Stage 1 categorised metrics that may be recorded as being part of a primary eye examination by their importance to research using the results from a previous survey of 40 vision science and public health academics. Delphi stage 2 then gauged the opinion of a panel of seven vision science academics and achieved consensus on contentious metrics and methods of grading/classification. RESULTS: A consensus regarding inclusion and response categories was achieved for nearly all metrics. A recommendation was made of 53 metrics which would be appropriate in a minimum data set. CONCLUSIONS: This minimum data set should be easily integrated into clinical practice yet allow vital data to be collected internationally from primary care optometry. It should not be mistaken for a clinical guideline and should not add workload to the optometrist. A pilot study incorporating an additional Delphi stage prior to implementation is advisable to refine some response categories.

[Ti] Título:Does the Badal optometer stimulate accommodation accurately?
[So] Source:Ophthalmic Physiol Opt;37(1):88-95, 2017 01.

[Ab] Resumo:PURPOSE: To study whether the accommodation response to Badal optometer is equivalent to the response for real space targets. METHODS: Accommodative responses were measured for 28 young eyes with the WAM-5500 autorefractometer in eight configurations for 0.17 D, 2.0 D and 5.0 D accommodation stimuli. Parameters that might contribute to differences in response were systematically isolated: stimulation method (real space vs Badal targets), field of view, instrument's cover proximity, the looming effect, and the peripheral interposition of objects in depth. RESULTS: Mean accommodative response differences between a natural view configuration and a configuration with a Badal Optometer were 0.50 ± 0.43 D and 0.58 ± 0.53 D for 2.0 D and 5.0 D stimulation, respectively (p < 0.001), with accommodation lags for the latter condition. Of the isolated parameters that might contribute to these differences, varying the interposition of objects in depth affected accommodation response more markedly. CONCLUSIONS: It is likely that Badal optometers affect accommodation through a combination of some or all of the studied parameters. We conclude that accommodation response to closed-view Badal optometers is not equivalent to real space target response.

[Ti] Título:Recommendations for analysis of repeated-measures designs: testing and correcting for sphericity and use of manova and mixed model analysis.
[So] Source:Ophthalmic Physiol Opt;37(5):585-593, 2017 Sep.
[Is] ISSN:1475-1313

[La] Idioma:eng
[Ab] Resumo:PURPOSE: A common experimental design in ophthalmic research is the repeated-measures design in which at least one variable is a within-subject factor. This design is vulnerable to lack of 'sphericity' which assumes that the variances of the differences among all possible pairs of within-subject means are equal. Traditionally, this design has been analysed using a repeated-measures analysis of variance (RM-anova) but increasingly more complex methods such as multivariate anova (manova) and mixed model analysis (MMA) are being used. This article surveys current practice in the analysis of designs incorporating different factors in research articles published in three optometric journals, namely Ophthalmic and Physiological Optics (OPO), Optometry and Vision Science (OVS), and Clinical and Experimental Optometry (CXO), and provides advice to authors regarding the analysis of repeated-measures designs. RECENT FINDINGS: Of the total sample of articles, 66% used a repeated-measures design. Of those articles using a repeated-measures design, 59% and 8% analysed the data using RM-anova or manova respectively and 33% used MMA. The use of MMA relative to RM-anova has increased significantly since 2009/10. A further search using terms to select those papers testing and correcting for sphericity ('Mauchly's test', 'Greenhouse-Geisser', 'Huynh and Feld') identified 66 articles, 62% of which were published from 2012 to the present. SUMMARY: If the design is balanced without missing data then manova should be used rather than RM-anova as it gives better protection against lack of sphericity. If the design is unbalanced or with missing data then MMA is the method of choice. However, MMA is a more complex analysis and can be difficult to set up and run, and care should be taken first, to define appropriate models to be tested and second, to ensure that sample sizes are adequate.

[Ti] Título:Coloured overlays and precision-tinted lenses: poor repeatability in a sample of adults and children diagnosed with visual stress
[So] Source:Ophthalmic Physiol Opt;37(4):542-548, 2017 07.
[Is] ISSN:1475-1313

[La] Idioma:eng
[Ab] Resumo:PURPOSE: Visual stress consists of perceived distortions or discomfort while reading. It is claimed that these symptoms are alleviated by viewing through coloured lenses or overlays, with a specific colour required for each individual. This has been explained on the basis of altered visual cortex excitation as affected by the spectral content of the viewing light. If symptoms are indeed alleviated by a particular colour that has an impact on the individual's visual system, we would expect that selection of the most beneficial colour would be repeatable. The aim of this study was to determine whether this is the case. METHODS: Twenty-one participants (mean age 26 years (range 8-55 years); 12 female, nine male) with visual stress and no other uncorrected ocular or visual anomaly were recruited. Each participant selected the colour most beneficial in alleviating their symptoms from a standard set of 10 coloured overlays, and underwent intuitive colorimetry in which the most beneficial of a wide range of chromatic illuminance settings was selected. Without prescribing an overlay at the first appointment, this process was repeated on a second occasion at a mean of 25 days later. RESULTS: About half of the participants (n = 10) chose the same (n = 7) or similar (with one common colour in both choices; n = 3) coloured overlay on the two occasions, while 11 participants chose a completely different overlay colour. Across all participants, the colorimetry setting shifted by, on average, 9.6 just noticeable differences, indicating that the colours were perceptually very different. CONCLUSION: These findings suggest that people with visual stress are unlikely to find exactly the same colour to be optimal on different occasions, and raise questions about the need for precise colour specification in tinted lenses for visual stress.

[Ab] Resumo:PURPOSE: To determine the effect of a protocol for a new physician-led, team-based glaucoma care model implemented in 2008 at Mayo Clinic's campus in Rochester, Minnesota (MCR), to increase conformance with the American Academy of Ophthalmology (AAO) Preferred Practice Pattern guidelines for treatment of primary open-angle glaucoma. METHODS: Records of 591 patients with newly diagnosed glaucoma were assessed retrospectively for the completion of 9 AAO Preferred Practice Pattern recommended metrics including measured corneal thickness, intraocular pressure (IOP), cup to disk ratio, visual acuity, recorded IOP target, gonioscopy, fundus photos, ocular coherence tomography, and visual field in the 3 years before and 3 years after protocol implementation. Treatment by the glaucoma care team at MCR was compared with treatment at a community-based general ophthalmology practice and with a group of comprehensive ophthalmologists at MCR without team care, which served as controls. RESULTS: Adherence to AAO recommendations increased for the documentation of target IOP (+24%, 42.6% to 66.7%; P=0.007), gonioscopy (+27%, 66.7% to 93.3%; P≤0.001), fundus photos (+29%, 44.4% to 73.3%; P≤0.001), and ocular coherence tomography (+20%, 48.1% to 68.0%; P=0.02) after protocol initiation. No change in pattern of testing occurred in the control groups without team care during the same time period. Type and severity of glaucoma were similar between MCR and community practice. CONCLUSIONS: An increase in compliance with AAO guidelines was found after implementation of our protocol for a physician-led, team-based care model to standardize glaucoma care among providers.

[Ti] Título:Surround Propinquity and Tonic Accommodation.

[Ab] Resumo:PURPOSE: Previous studies of dark focus have found evidence of a propinquity response, in which subjects accommodate to the perceived distance of their surroundings despite being in absolute darkness. Their distance perception in a lighted room allows a spatial representation to persist within the darkened room. This study sought to establish the significance and magnitude of the propinquity response in a large sample of young adults, and to determine whether the propinquity response can be predicted by a subject's initial dark focus in an unknown dark room. METHODS: Dark focus was measured with a dynamic infrared optometer (Plusoptix PowerRef 3) in 30 young adult subjects, 26 of whom were naive to the testing room and its dimensions. Dark focus was then measured at varying dioptric wall distances of 0.25-4D. The subject viewed the lighted room before each measurement. For each individual, the dark focus was plotted as a function of dioptric wall distance. The slope of this function was used as a measure of the propinquity response. RESULTS: The mean initial dark focus value was 1.05D (SD 1.04D) for the 26 naive subjects. The mean slope of the plot of dark focus as a function of dioptric wall distance was small (+0.097), yet highly statistically significant (P = .0002). The propinquity response function showed no statistically significant quadratic or cubic trends, and so may be considered linear. No statistically significant correlation was found between naive dark focus and propinquity response (r = +0.246, P = .226). CONCLUSIONS: Propinquity seems to be a small but statistically significant factor in dark focus measurements. Though it is unlikely to contaminate tonic accommodation measurements in large samples under normal laboratory conditions, a minority of individuals exhibit large propinquity responses equal to that of proximal accommodation in lighted conditions.

[Ab] Resumo:PURPOSE: To investigate practice patterns of eye care providers at academic medical centers in the United States (US) with regard to assessing patients' smoking status and exposure, educating patients regarding ocular risks of smoking, and counseling patients about smoking cessation. DESIGN: Cross-sectional survey. METHODS: An anonymous survey including multiple choice and Likert-style questions was constructed on http://www.surveymonkey.com and emailed to the coordinators of all 113 US ophthalmology residency programs, with a request to forward to all faculty, fellows, residents, and optometrists at their institution. Main outcome measures include proportion of eye care providers who assess patients' smoking status, educate patients regarding ocular risks of smoking, and discuss with patients smoking cessation options. RESULTS: Of the 292 respondents, 229 (78%) "always" or "periodically" ask patients about their smoking status, 251 (86%) "seldom" or "never" ask patients about secondhand smoke exposure, 245 (84%) "always" or "periodically" educate patients about ocular diseases associated with smoking, 142 (49%) "seldom" or "never" ask patients who smoke about their willingness to quit smoking, and 249 (85%) "seldom" or "never" discuss potential methods and resources to assist with smoking cessation. CONCLUSIONS: Most eye care providers assess patients' smoking status and educate patients regarding ocular risks of smoking. However, approximately half do not ask, or seldom ask, about patients' willingness to quit smoking, and most do not discuss smoking cessation options.

[Ti] Título:A novel rat head gaze determination system based on optomotor responses.
[So] Source:PLoS One;12(4):e0176633, 2017.

[Ab] Resumo:The optomotor response of animals is commonly used to measure their visual performance, e.g., rats of different genetically altered strains or various drug tests. With the presentation of stimuli using computer screens or projectors, the common idea focuses on measuring the eye movement or head and/or body movement to characterize changes of the head gaze. However, traditional methods rely on either the invasive fixation of animals, or the judgment of a human observer who reports the stimulus-tracking movements. In this paper, we propose a novel head gaze determination system to automatically track the head movement of rats without artificial markers. The experiments were done to demonstrate the process of optimizing parameters in image processing. As a result, the head angle curve of the proposed method is consistent with that of ground-truth data annotated manually according to predefined rules. Hence, the proposed method provides a simple, convenient, and objective solution to automatically generate the head gaze orientations from massive amounts of recorded data for further visual performance analysis.

[Ti] Título:Accommodative amplitude using the minus lens at different near distances.

[Ab] Resumo:PURPOSE: The purpose of this study was to compare the mean findings and the repeatability of the minus lens (ML) amplitude of accommodation (AA) at 33 cm and 40 cm. MATERIALS AND METHODS: AA was measured from the dominant eye of 120 fully corrected subjects using the ML procedure when viewing the target at both 33 and 40 cm. Each measurement was repeated between 24 and 48 hours after the first trial. RESULTS: Mean AA when tested at 33 cm and 40 cm was 10.20 diopter (D) (standard deviation [SD] =1.24) and 8.85 D (SD = 1.23), respectively (P < 0.001). The limits of agreement of the measured amplitude calculated with taking into account of the replicates at 33 and 40 cm were - 0.19 (95% confidence interval [CI]: -0.34 to -0.04) and 2.53 (95% CI: 2.38 to 2.68), respectively. The repeatability of testing at the two distances 33 and 40 cm was ± 1.24 and ± 0.99, respectively. In addition, the retest reliability of measured amplitude using the intraclass correlation coefficient was 0.87 (95% CI: 0.789-0.920) at 33 cm and 0.91 (95% CI: 0.872-0.945) at 40 cm. CONCLUSION: There is no agreement in the obtained amplitude at the two measurement distances. Testing the ML AA at 40 cm may be superior given that a lower repeatability coefficient was observed. However, it is unclear whether the larger amplitude measured at 33 cm reflects a larger increase in accommodation (greater proximity effect) or a decrease in the ability to perceive the first slight sustained blur.
