Special Issue Information

Dear Colleagues,

The integration of advanced technologies in the field of optometry and ophthalmology has significantly transformed the detection, diagnosis, and treatment of ocular diseases. This Special Issue focuses on the latest advancements in these technologies, highlighting their practical applications and clinical benefits.

Innovations in Eye Care Technologies

The development of new technologies for the detection and treatment of ocular diseases has enabled more precise diagnoses and more effective treatments. Artificial intelligence (AI) and machine learning have revolutionized ophthalmic diagnosis by providing tools that can analyze large volumes of data quickly and accurately. These technologies are now used to detect diseases such as diabetic retinopathy, macular degeneration, and glaucoma, improving clinical outcomes and facilitating early interventions.

Advances in Optical Coherence Tomography (OCT)

Optical coherence tomography (OCT) is an essential tool in ophthalmic diagnosis. Improvements in OCT techniques have led to higher resolution and precision, allowing physicians to visualize ocular structures in greater detail. Emerging applications of OCT in optometry include the assessment of myopia progression and the early detection of retinal pathologies, offering a non-invasive and highly effective approach for monitoring ocular diseases.

Telemedicine in Optometry

The implementation of telemedicine in eye care has facilitated access to diagnoses and treatments, especially in rural or underserved areas. Teleconsultation technologies allow optometrists and ophthalmologists to perform eye exams and consultations remotely, reducing the need for in-person visits. This not only improves the efficiency of eye care but also increases accessibility for patients.

Virtual Reality Devices in Optometry

Virtual reality (VR) devices are transforming the evaluation and treatment of ocular diseases, offering a more interactive and precise way to assess various visual parameters. In the field of perimetry, VR facilitates the early detection and monitoring of diseases such as glaucoma by providing a detailed evaluation of visual fields. Additionally, VR devices are used for depth perception tests, visual acuity assessments, and visual skills training, among others. This significantly enhances the patient experience and provides more precise and reliable data for eye care professionals.

Augmented reality (AR) technologies can improve the quality of life of individuals with visual impairments. The current study evaluated the efficacy of Retiplus, a new AR-based low-vision device, which was designed to enhance spatial awareness and visual function in patients with peripheral visual field loss. Thirteen patients diagnosed with retinitis pigmentosa (RP) participated in this study. The patients’ visual acuity, visual field, and subjective perception of peripheral vision and mobility were assessed both without and with the AR aid, following a training period consisting of five 1 h sessions. The results showed a significant expansion of the visual field (VF) in all four quadrants (right, left, upper, and lower) with a greater horizontal diameter enlargement (21.38° ± 12.94°) than vertical (15° ± 10.08°), with a statistically significant difference. However, the increase in VF was accompanied by a modest reduction in visual acuity due to the minification of the image on the display. Patient feedback also highlighted significant benefits on the ability to perform activities of daily living (ADL) in low-light environments and improved spatial orientation, suggesting that the AR system is helpful for some limitations imposed by patients’ conditions. These findings underscore the importance of optimizing AR technology to support visually impaired populations. Full article

Background: This study aims to evaluate subjective visual fatigue and objective optical and morphological changes in ocular structures after intermediate-duration reading on an iPad and an Ebook across different age groups. Methods: The sample included 108 right eyes from healthy subjects aged 18 to 66 years. The participants read for 20 min on an Ebook and another 20 min on an iPad under controlled illumination conditions. Aberrometry and retinal optical coherence tomography (OCT) measurements were taken before and after each reading session. Parameters such as total aberration, high-order aberration (HOA), low-order aberration (LOA), and retinal thickness in the nine Early Treatment Diabetic Retinopathy Study (ETDRS) areas were measured. The sample was analyzed as a whole and divided into five age groups by decade. Results: This study included 66 women (61.11%) and 42 men (38.89%), with an average age of 36.58 years (±14.83). The aberrometry results revealed significant differences in the total root mean square (RMSTOTAL) after reading on both devices (p = 0.001). Low-order aberrations (RMSLOA) also changed significantly (p = 0.001 for Ebook, p = 0.002 for the iPad), but high-order aberrations (RMSHOA) did not. Central retinal thickness increased significantly after reading on the Ebook (p < 0.001) but not on the iPad. The peripheral retinal thickness did not change significantly. Conclusion: Moderate-duration reading increases LOA and central retinal thickness, with variations by age group and more pronounced effects from the Ebook, whereas HOA remains unaffected.
