Exposure to ambient air pollution is associated with several noncommunicable diseases, and it adversely affects the respiratory system and other organ systems. Several studies have investigated the underlying mechanisms of biological response to air pollutants using conventional techniques, but there is a lack of research on the effects of air pollution at the cellular level. This study developed a dual system that combines PM (particulate matter <2.

Article Synopsis
  • - Corneal haze results from abnormal healing processes following injuries or surgeries, causing vision impairment due to eye opacity and irregularities, often linked to myofibroblast formation triggered by inflammation.
  • - Major causes of corneal haze include surgical procedures like PRK and LASIK, as well as non-surgical factors such as trauma and infections, with research focusing on the TGFβ pathway and inflammation management methods.
  • - Losartan, usually used for treating high blood pressure, shows promise in ophthalmology for reducing corneal fibrosis after various injuries and surgeries, leading to this review of its effectiveness and potential future applications in treating corneal haze.

Purpose: The purpose of this study was to compare early visual outcomes, epithelial healing, and stromal haze between transepithelial photorefractive keratectomy (Trans-PRK) using smart pulse technology (SPT) with traditional Trans-PRK.

Methodology: This study is a retrospective, comparative study conducted at a private eye center in "Riyadh, Saudi Arabia," investigating myopic patients who underwent either Trans-PRK with SPT (study group) or traditional Trans-PRK (control group). The patients were assessed preoperatively and followed up at 1 week and 2 months postoperatively.

In this case series, we will describe sterile keratitis in the early postoperative period after hypotonic collagen cross-linking (CXL) in two pediatric cases. This is a retrospective case series of two eyes of two children who developed inflammatory keratitis with central corneal haze after uneventful epithelial-off hypotonic CXL. After ensuring microbiological sterility, appropriate treatment with topical steroids and lubricants was started.

Purpose: To report on the clinical characteristics, and outcomes of patients who developed infectious keratitis associated with contact lens (CL) wear following penetrating keratoplasty (PK).

Methods: A retrospective chart review was performed to identify all patients who underwent PK between November 2012 and January 2023 at a single tertiary referral practice, and subsequently developed CL related infectious keratitis. 74 patients using CL following PK were identified.
