Methods: Sixty eyes of 30 myopic individuals with at least -2.50 diopters (D) of spherical equivalent and 3.

Serum Vitamin D Levels in Patients with Vernal Keratoconjunctivitis: A Systematic Review and Meta-Analysis.

Purpose: To conduct a systematic review and meta-analysis to provide an outline of available data on the association between serum vitamin D levels and vernal keratoconjunctivitis (VKC) and to determine the possible relationship in children.

Methods: Systematic research on all articles published until July 2023 was conducted in PubMed, SCOPUS, Web of Science, and Embase. All observational-analytical studies that measured vitamin D levels in patients with VKC were included.

Retinal and choroidal thickness in fuchs uveitis syndrome: a contralateral eye study.

Background: To investigate the subfoveal retinal and choroidal thickness in patients with unilateral Fuchs Uveitis Syndrome (FUS).

Methods: This comparative contralateral study was performed in affected eyes with FUS versus fellow eyes. For each eye parameters such as subfoveal choroidal thickness (SCT), subfoveal choriocapillary thickness (SCCT), central macular thickness (CMT), and central macular volume (CMV) were measured; then the measured values of affected and fellow unaffected eye were compared.

Comparing the Effectiveness and Safety of Giving Fentanyl or Ketamine Intranasally during Phacoemulsification Surgery.

Background: Phacoemulsification is the main method of cataract surgery in developed countries. Due to the importance of appropriate analgesia and the immobility of the participants throughout the procedure, the study aimed to assess the impact of intranasal ketamine vs. intranasal fentanyl on the quality of sedation and analgesia in phacoemulsification surgery.

Characteristics of Hospitalized Pediatric Patients Following Traumatic Open Globe Injuries; a Cross-sectional Study.

Introduction: One of the main causes of acquired blindness and impairment in children is ocular trauma. This study aimed to evaluate the epidemiological and clinical characteristics of pediatric patients hospitalized with open globe injuries (OGI).

Methods: A retrospective cross-sectional study was conducted on children diagnosed with OGI at a referral Hospital affiliated with Isfahan University of Medical Sciences, Isfahan, Iran, from 2014 to 2018.

A new computer-aided diagnosis tool based on deep learning methods for automatic detection of retinal disorders from OCT images.

Purpose: Early detection of retinal disorders using optical coherence tomography (OCT) images can prevent vision loss. Since manual screening can be time-consuming, tedious, and fallible, we present a reliable computer-aided diagnosis (CAD) software based on deep learning. Also, we made efforts to increase the interpretability of the deep learning methods, overcome their vague and black box nature, and also understand their behavior in the diagnosis.

Corneal biomechanics in normal and subclinical keratoconus eyes.

Background: The diagnosis of keratoconus, as the most prevalent corneal ectatic disorder, at the subclinical stage gained great attention due to the increased acceptance of refractive surgeries. This study aimed to assess the pattern of the corneal biomechanical properties derived from Corneal Visualization Scheimpflug Technology (Corvis ST) and evaluate the diagnostic value of these parameters in distinguishing subclinical keratoconus (SKC) from normal eyes.

Methods: This prospective study was conducted on 73 SKC and 69 normal eyes.

Association of Patient Satisfaction with Cataract Grading in Five Types of Multifocal IOLs.

Introduction: This study investigated patient satisfaction levels in five premium intraocular lenses (IOLs). A secondary aim was to determine whether patient satisfaction was associated with the cataract grade before lens surgery.

Methods: In this multicenter prospective comparative study, 164 patients from diverse backgrounds underwent cataract surgery and were assigned for identical bilateral implantation of multifocal IOLs.

Automatic Choroidal Segmentation in Optical Coherence Tomography Images Based on Curvelet Transform and Graph Theory.

Background: Automatic segmentation of the choroid on optical coherence tomography (OCT) images helps ophthalmologists in diagnosing eye pathologies. Compared to manual segmentations, it is faster and is not affected by human errors. The presence of the large speckle noise in the OCT images limits the automatic segmentation and interpretation of them.

Recurring nodular scleritis following inactivated vaccination for COVID-19.

Key Clinical Message: Though COVID-19 vaccination saved many lives all around the world, it has had many adverse effects including ophthalmologic side effects. It is important to report such adverse effects to provide timely diagnosis and management.

Abstract: Since the COVID-19 global outbreak, many types of vaccines have been introduced.

Combined simultaneous photorefractive keratectomy and collagen cross-linking in keratoconus suspect patients.

Purpose: To evaluate the safety and efficacy of combined simultaneous photorefractive keratectomy (PRK) with collagen cross-linking (CXL) in keratoconus suspects (KCS).

Methods: This was a retrospective, non-randomized study of KCS patients who underwent combined simultaneous PRK with CXL. The efficacy, safety, refractive outcomes, and corneal wavefront aberration changes were assessed after the surgery and compared with existing preoperative data.

Evaluation of Exposure to Radiofrequency Electromagnetic Fields from Smart Utility Meters operating at 868 MHz.

Power density and duty factor values were measured around smart utility meters operating at 868 MHz under laboratory-controlled conditions. The maximum 6-min averaged exposure recorded was 0.1 mWm , which is less than 0.

A systematic review of sarcopenia prevalence and associated factors in people living with human immunodeficiency virus.

People living with human immunodeficiency virus (HIV) (PLWH) appear to be at an increased risk of sarcopenia, which can have a devastating effect on their life due to consequences such as physical disability, poor quality of life, and finally death. This systematic review examined sarcopenia prevalence and its associated factors in PLWH. A systematic search was conducted using the keywords in the online databases including Scopus, PubMed, Web of Science, Embase and Cochrane databases from the dates of inception up to May 2022.
