Ocular Complications after COVID-19 Vaccination: A Systematic Review.

Background and Objectives: The COVID-19 pandemic affects various populations worldwide. The discovery of vaccinations was necessary for the prevention and elimination of the disease. Despite the high importance of these vaccinations, they may cause some complications, such as ocular complications. This study aims to draw attention to the possible complications of the vaccination and highlight its importance. Materials and Methods: Systematic review of the literature from January 2021 to January 2023. A total of 20 published articles were included and reported cases of ocular complications in patients who received COVID-19 vaccines. Results: A total of 243 patients with verified ocular complications following the COVID-19 vaccination were included, ranging in age from 18 to 84 years. The most common ocular complications reported in the current study were ocular inflammatory complications, which represented 47.3%, followed by optic neuritis (24.3%). Retinal artery occlusion, retinal vein occlusion, acute macular neuroretinopathy, and paracentral acute middle maculopathy represented 10.7%. Herpetic ocular infections and herpetic eye disease (14%). Nearly half (42%) of the patients with ocular problems received the Pfizer-BioNTech vaccination. Conclusions: Despite the high importance of the COVID-19 vaccination, it was found that it is associated with the occurrence of some ocular complications. Future projects should come with more extensive prospective studies to further elucidate the underlying mechanisms and risk factors associated with ocular complications following COVID-19 vaccination, thereby enhancing our understanding and guiding appropriate management strategies.

Parents' Awareness, Knowledge, and Perception of Amblyopia in Children: A Study in Jazan Region, Saudi Arabia.

Background Amblyopia is a vision disorder that results from a development problem in the brain rather than a neurological disease in the eye. The condition causes reduced visual acuity in one or both eyes due to the brain's inability to process inputs, rather than a structural abnormality. This study aims to assess parents' awareness, knowledge, and perception of amblyopia in their children in the Jazan region, Saudi Arabia. Methods This is a cross-sectional study that used an electronic questionnaire consisting of five main sections to assess the level of awareness of amblyopia among parents in the Jazan region. The Statistical Package for Social Sciences (SPSS v.25, IBM Corp., Armonk, NY, USA) was utilized to input the data. The degree to which participants' level of awareness was related to variables such as age, gender, and educational level was assessed through the chi-square test (χ2), and any values that scored p-values under 0.05 were deemed statistically significant. Results The analysis included 572 participants, 395 mothers (69.0%) and 177 fathers (31.0%). The age groups of the participants were divided into 36-45 years (38.0%), 26-35 years (36.0%), and above 46 years (17.0%). Out of the total, 36 participants (6.0%) had a history of amblyopia, and 73 (13.0%) had a child who suffered from amblyopia. The findings showed that only 18 participants (3.1%) had a good awareness of amblyopia, while 242 (42.3%) had a fair level of awareness. Most participants, 312 (54.5%), were classified as having a poor awareness level of amblyopia. Parents with postgraduate degrees, those with prior awareness, and parents whose children had eye diseases demonstrated higher levels of good awareness. However, gender, age, and residency did not have significant associations with awareness levels. Conclusion While parents must be involved in managing amblyopia, our research found that more than half of the parents surveyed had a limited understanding of various aspects of the disease, which can cause permanent damage to their child's vision. Therefore, we recommend implementing health education programs to increase awareness and knowledge about amblyopia in Jazan.
