- Efficacy and Patients' Satisfaction with the ORCAM MyEye Device Among Visually Impaired People: A Multicenter Study(2023) AMORE, Filippo; SILVESTRI, Valeria; GUIDOBALDI, Margherita; SULFARO, Marco; PISCOPO, Paola; TURCO, Simona; ROSSI, Francesca De; RELLINI, Emanuela; FORTINI, Stefania; RIZZO, Stanislao; PERNA, Fabiana; MASTROPASQUA, Leonardo; BOSCH, Vanessa; OEST-SHIRAI, Luz Ruriko; HADDAD, Maria Aparecida Onuki; HIGASHI, Alez Haruo; SATO, Rodrigo Hideharo; PYATOVA, Yulia; DAIBERT-NIDO, Monica; MARKOWITZ, Samuel N. N.To evaluate usability of and satisfaction with OrCam MyEye, a finger-size wearable assistive technology device for visually impaired during real-world tasks. This prospective multicenter study was conducted on visually impaired people recruited from 5 vision rehabilitation centers. Patients performed real-world tasks such as near and distance reading, money handling, colour identification and face recognition in 2 different scenarios: without using any low vision aid and with OrCam. System Usability Scale (SUS), Patient's Global Impression of Change (PGIC), the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0) and the Psychosocial Impact of Assistive Devices Scale (PIADS) were administered after the use of the OrCam device. Among the 100 participants, use of OrCam MyEye device improved many daily-living tasks (F = 1.67, P < .05), and in particular reading and face recognition. Multivariate logistic regression showed that age and visual field defect explained 89% of the variation in efficacy of the device. Nearly half (45%) of the participants indicated a positive rating with the SUS. The PGIC rates showed a minimal improvement with a mean score of 4.2 (SD:1.8). The most highlighted parameter with the QUEST 2.0 test was ""ease of use"" in 58% (48 subjects). The PIADS indicator showed that the device positively impacted on the daily-living tasks of users (r(2) = 0.72, P < .05). Regression modelling demonstrated a good relation between the questionnaires scores and demographic, disease and visual factors (P < .05). OrCam MyEye allowed visually impaired people to read, handle money and face recognition independently. This device may offer to these subjects to be independent.
- Normative data for macular perimetry using the MP-3 microperimeter in healthy individuals(2024) NETO, Taurino dos Santos Rodrigues; NETO, Epitacio Dias da Silva; HIGASHI, Alex Haruo; MEGNIS, Bianca Partezani; HADDAD, Maria Aparecida Onuki; MONTEIRO, Mario Luiz Ribeiro; ZACHARIAS, Leandro CabralPurpose: Microperimetry has been used for several years as a form of visual function testing in patients with retinal diseases. Normal microperimetry values obtained with microperimeter MP-3 have not yet been fully published, and baseline values for topographic macular sensitivity and correlations with age and sex are needed to establish degrees of impairment. This study aimed to determine values for light sensitivity thresholds and fixation stability using the MP-3 in healthy individuals. Methods: Thirty-seven healthy volunteers (age, 28-68 years), underwent full-threshold microperimetry using a 4-2 (fast) staircase strategy with the standard Goldmann III stimulus size and 68 test points positioned identically to those in the Humphrey Field Analyzer 10-2 test grid. The fixation stability was simultaneously recorded during the microperimetry test. The relationship between global sensitivity and age was calculated using linear regression analysis. Results: Microperimetry was performed on 37 participants (74 eyes). The global mean sensitivity was 29.01 +/- 1.44 (range, 26-31) dB. The mean central sensitivity at 2 degrees measured by the MP-3 was 28.5 +/- 1.77 dB in the right eye (OD) and 28.75 +/- 1.98 dB in the left eye (OS). The total median fixation stability values within 2 degrees and 4 degrees were 80% and 96%, respectively. The linear regression analysis also revealed an age-related global sensitivity decline per year of -0.051 dB +/- 0.018 (OD) and -0.078 dB +/- 0.021 (OS). Conclusions: Microperimetry performed with the MP-3 allows for an automatic, accurate, and topography-specific examination of retinal sensitivity thresholds. The results of this study provide a normal and age-matched database of MP-3 microperimetry.
- OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY BIOMARKERS AND MICROPERIMETRY FEATURES IN BEHÇET'S UVEITIS(2023) FERREIRA, Bruno F. A.; HIGASHI, Alex H.; PRADO, Leandro L.; GONCALVES, Celio R.; HADDAD, Maria A. O.; ZACHARIAS, Leandro C.; HIRATA, Carlos E.; YAMAMOTO, Joyce H.Purpose: To evaluate the parafoveal macular microvasculature and the macular function in patients with retinal vasculitis associated with Beh & ccedil;et's uveitis.Methods: In 14 patients with inactive Beh & ccedil;et's uveitis and 26 control individuals (13 with nonocular Beh & ccedil;et's syndrome and 13 healthy subjects), we analyzed the retinal nerve fiber layer, ganglion cell layer, full retinal thickness, foveal avascular zone area and sectorial parafoveal vascular density in the superficial vascular plexus, intermediate capillary plexus, and deep capillary plexus using SPECTRALIS optical coherence tomography (OCT) 2 and OCT angiography. Macular sensitivity was analyzed using an MP-3 microperimeter.Results: Eighteen eyes (78%) had a best-corrected visual acuity >= 20/25. Significant differences were found in Beh & ccedil;et's uveitis in comparison with the controls on the OCT and OCT angiography: 14.8%, 22.4%, and 14.9% ganglion cell layer thinning in the global, nasal, and inferior sectors, respectively; 6%, 13.2%, and 7.5% full retinal thickness thinning in the superior, nasal, and inferior sectors; and 16.8%, 14.9%, 23.6%, 15.8%, and 12.6% mean deep capillary plexus density reduction in the global, superior, nasal, inferior, and temporal sectors. Microperimetry data demonstrated significant mean reductions of 21% and 23.6% in central and average macular sensitivities and 28.8%, 40.4%, 27.7%, and 24.2% in the superior, nasal, inferior, and temporal sectors, respectively. Outer plexiform layer elevations were observed in Beh & ccedil;et's uveitis (69.6%).Conclusion: Beh & ccedil;et's uveitis presented structural and functional macular damage despite good best-corrected visual acuity, mainly affecting the nasal sector and the deep capillary plexus. On OCT and OCT angiography, quantitative and qualitative changes can be valuable biomarkers of ocular involvement in Beh & ccedil;et's syndrome.
