advanced dry eye screening for Visual display terminal workers using functional Visual Acuity Measurement the moriguchi study
British Journal of Ophthalmology, 2015Co-Authors: Minako Kaido, Norihiko Yokoi, Motoko Kawashima, Hiroaki Kato, Masaki Fukui, Yoshiyuki Ichihashi, Motoko Yamatsuji, Mitsuko Nishida, Kazumi Fukagawa, Shigeru KinoshitaAbstract:Purpose To evaluate the validity of a dry eye (DE) screening method in Visual display terminal (VDT) workers using functional Visual Acuity (VA) Measurement combined with a symptoms questionnaire, and to make recommendations regarding practical use of the screening. Methods This prospective cross-sectional study included 369 young and middle-age office workers, who use VDTs. Subjects completed two types of DE questionnaires and underwent DE testing and functional VA Measurement. Subjects were assigned to DE and non-DE groups. Sensitivity and specificity of the DE prediction value were assessed. According to the probability distribution of DE and non-DE calculated by the discriminant analysis formula, we classified subjects into three categories based on the most appropriate cut-off levels. Positive predictive value (PPV) and negative predictive value (NPV) of the DE prediction value were also assessed. Results Of 369 subjects, 218 and 151 subjects were assigned to the DE and non-DE groups, respectively. Sensitivity and specificity were 93.1% and 43.7%, respectively. Based on the probability prediction, the cut-off levels were defined as probability prediction ≥85%, 45%≤ probability prediction Conclusions Acceptable PPV and NPV were obtained by setting three discriminate categories. This improved version of the DE screening method may be acceptable for practical use in VDT workers.

dry eye screening by using a functional Visual Acuity Measurement system the osaka study
Investigative Ophthalmology & Visual Science, 2014Co-Authors: Minako Kaido, Murat Dogru, Miki Uchino, Norihiko Yokoi, Yuichi Uchino, Motoko Kawashima, Aoi Komuro, Yukiko Sonomura, Hiroaki Kato, Shigeru KinoshitaAbstract:PURPOSE. We determined whether functional Visual Acuity (VA) parameters and a dry eyes (DEs) symptoms questionnaire could predict DEs in a population of Visual terminal display (VDT) users. METHODS. This prospective study included 491 VDT users from the Osaka Study. Subjects with definite DE, diagnosed with the presence of DE symptoms, tear abnormality (Schirmer test � 5 mm or tear breakup time [TBUT] � 5 seconds), and conjunctivocorneal epithelial damage (total staining score of ‡3 points), or probable DE, diagnosed with the presence of two of them, were assigned to a DE group, and the remainder to a non-DE group. Functional VA was assessed, and DE questionnaires were administered. We assessed whether univariate and discriminant analyses could determine to which group a subject belonged. Sensitivity and specificity were assessed. RESULTS. Of 491 subjects, 320 and 171 were assigned to the DE and non-DE groups, respectively. No significant differences were observed between DE and non-DE groups in Schirmer test value and epithelial damage, but TBUT value (3.1 6 1.5 vs. 5.9 6 3.0 seconds). The sensitivity and specificity of single test using functional VA parameters were 59% and 49% in functional VA, 60% and 50% in Visual maintenance ratio, and 83% and 30% in frequency of blinking, respectively. According to a discriminant analysis using a combination of functional VA parameters and a DE questionnaire, six variables were selected for the discriminant equation, of which area under the curve (AUC) was 0.735. Sensitivity and specificity of diagnoses predicted by the discriminant equation were 85.9% and 45.6%, respectively. CONCLUSIONS. The discriminant equation obtained using functional VA Measurement combined with a symptoms questionnaire may suggest the possibility for the first step screening of DE with unstable tear film. Since the questionnaire has an overall poor sensitivity and specificity, further amelioration may be necessary for the actual utilization of this screening tool.

The effect of tinted soft contact lens wear on functional Visual Acuity and higher-order aberrations
Contact Lens and Anterior Eye, 2014Co-Authors: Kazuhiro Watanabe, Minako Kaido, Murat Dogru, Reiko Ishida, Kazuno Negishi, Keishi TsubotaAbstract:Purpose: To investigate the differences of functional Visual Acuity (FVA) and high order aberrations (HOAs) in relation to tinted and clear hydrogel soft contact lens (SCL) wear. Methods: A prospective comparative study was performed in 16 eyes of 16 healthy volunteers. Dynamic Visual Acuity (using a FVA Measurement system) and higher-order aberrations (using a wavefront sensor) were compared in subjects wearing two types of soft contact lenses: 1-day Acuvue®(Vistakon, Jacksonville, FL) clear and the 1-day Acuvue®DefineTM(Vistakon, Jacksonville, FL) tinted lens. The blink rates were recorded during FVA testing. The correlation between the difference of HOAs and differences in FVA values was analyzed. Results: The mean LogMAR FVA scores with clear and tinted SCLs were 0.07 ± 0.13 and 0.14 ± 0.17 (P< 0.05). The mean blink frequencies with clear and tinted SCL wear were 18.4 ± 8.3 and 25.3 ± 4.7. blinks/min (P< 0.05). Both 3rd-order aberrations and total HOAs showed statistically significant differences between the two types of soft contact lenses for 6. mm pupil Measurements (P< 0.05). A significant positive linear correlation was observed between δHOAs and δLogMAR FVA for 6. mm pupil Measurements (R= 0.53, P= 0.04). Conclusions: Tinted contact lens wear appears to induce a reduction in optical quality. Functional Visual Acuity Measurement is a useful procedure to study the changes of Visual performance and quality in tinted contact lens wear. © 2013 British Contact Lens Association.

The relation of functional Visual Acuity Measurement methodology to tear functions and ocular surface status
Japanese Journal of Ophthalmology, 2011Co-Authors: Minako Kaido, Murat Dogru, Reiko Ishida, Keishi TsubotaAbstract:Purpose To investigate the relation of functional Visual Acuity (FVA) Measurements with dry eye test parameters and to compare the testing methods with and without blink suppression and anesthetic instillation. Design A prospective comparative case series. Methods Thirty right eyes of 30 dry eye patients and 25 right eyes of 25 normal subjects seen at Keio University School of Medicine, Department of Ophthalmology were studied. FVA testing was performed using a FVA Measurement system with two different approaches, one in which Measurements were made under natural blinking conditions without topical anesthesia (FVA-N) and the other in which the Measurements were made under the blink suppression condition with topical anesthetic eye drops (FVA-BS). Tear function examinations, such as the Schirmer test, tear film break-up time, and fluorescein and Rose Bengal vital staining as ocular surface evaluation, were performed. Results The mean logMAR FVA-N scores and logMAR Landolt Visual Acuity scores were significantly lower in the dry eye subjects than in the healthy controls ( p < 0.05), while there were no statistical differences between the logMAR FVA-BS scores of the dry eye subjects and those of the healthy controls. There was a significant correlation between the logMAR Landolt Visual acuities and the logMAR FVA-N and logMAR FVA-BS scores. The FVA-N scores correlated significantly with tear quantities, tear stability and, especially, the ocular surface vital staining scores. Conclusions FVA Measurements performed under natural blinking significantly reflected the tear functions and ocular surface status of the eye and would appear to be a reliable method of FVA testing. FVA Measurement is also an accurate predictor of dry eye status.

the application of a new continuous functional Visual Acuity Measurement system in dry eye syndromes
American Journal of Ophthalmology, 2005Co-Authors: Minako Kaido, Murat Dogru, Reiko Ishida, Takashi Kojima, Yukihiro MatsumotoAbstract:PURPOSE: To evaluate the efficacy of a new continuous functional Visual Acuity Measurement (FVAM) system for the assessment of dry eye patients. DESIGN: Prospective comparative study. METHODS: Monocular recognition Acuity measured continuously by the FVAM system during a 30-second blink-free period was defined as functional Visual Acuity (FVA). Examinations using the FVAM system were conducted in 35 eyes of 20 healthy controls and 19 eyes of 13 dry eye patients. Tear function examinations including the Schirmer test, tear film break-up time, and fluorescein and Rose Bengal staining were performed in all subjects. Functional Visual Acuity and tear functions were also examined before and after insertion of punctum plugs in dry eye patients. Functional Visual Acuity results at 10, 20, and 30 seconds were compared. RESULTS: Functional Visual Acuity in dry eyes were significantly lower than control subjects at all time points (P < .05). Functional Visual Acuity after punctum plugs insertion improved significantly at all time points (P < .05). CONCLUSIONS: FVAM system seemed not only to be an effective tool in the assessment of dynamic Visual Acuity changes in dry eye and normal subjects but in evaluating the outcome of management of dry eye disease by punctum plugs.
