Summary: The widespread use of mobile devices and associated technologies has had a significant impact on the lives of people with visual impairments. Mobile apps have become a popular choice for assisting with various visual tasks due to their affordability, versatility, portability, and ubiquity. However, there is a lack of rigorous evaluation studies on the effectiveness of vision assistance apps and establishing evaluation criteria due to the heterogeneous nature of visual tasks and user needs.

Summary: This systematic review summarizes research on the psychological implications of vitreous opacities in adult patients. The findings suggest that patients with vitreous opacities experience higher levels of depression, perceived stress, and anxiety compared to healthy controls. They also have reduced vision-related quality of life and social functioning. Medical treatments, such as pars plana vitrectomy, have a significant positive impact on patients' mental health and quality of life.

Summary: Through a systematic review and meta-analysis of the current literature, the effect of COVID-19 on retinal tissues was evaluated. The findings indicate that COVID-19 can profoundly affect the retina, as evidenced by reduced central retinal vascular density, thinner ganglion cell layer, thicker retinal nerve fibre layer, enlarged foveal avascular zone, and other changes observed in optical coherence tomography scans and fundus photographs. Long-term follow-up of COVID-19 patients is necessary to assess the reversibility of retinal damage caused by the virus.

Summary: This systematic literature review investigates patient-reported outcomes, mental health, and caregiver burden in patients with neovascular age-related macular degeneration (nAMD) treated with anti-vascular endothelial growth factor (VEGF) agents. The results show that up to 42% of patients with nAMD report depression or depressive symptoms. Studies indicate that anti-VEGF treatment significantly improves quality of life, with approximately 50% of patients experiencing sustained benefits at 12 months. Patients show a preference for the treat and extend regimen, which is associated with reduced patient and caregiver burden compared to fixed dosing.

Summary: The purpose of this study was to compare the clinical effectiveness, safety, and cost-effectiveness of subthreshold micropulse laser (SML) and standard laser (SL) for diabetic macular edema (DME) with central retinal thickness (CRT) < 400 μm. The results showed that SML therapy was equivalent to SL therapy and required slightly more laser treatments.

Summary: This study explores the characteristics of choroidal tissue in patients with and without central serous chorioretinopathy (CSC) using an automated system of image analysis to determine known and novel metrics. The results show significant increases in choroidal vascularity index, choroidal thickness indices, and some novel measures in patients with CSC, while the ratio of vessel lumen to stromal tissue intensity is significantly reduced. These findings contribute to further assessment and research on conditions affecting choroidal tissue.
