Article Synopsis
  • Neutrophils play a critical role in the immune response to herpes simplex virus type 1 (HSV-1) ocular infections through the formation of neutrophil extracellular traps (NETs), which help combat the virus.
  • The study involved analyzing neutrophils from mice and human tear samples to understand the timing and mechanisms of NET formation during HSV-1 infection.
  • Findings showed that NET formation is activated quickly through signals like caspase-1 and myeloperoxidase, suggesting that NETs are important for limiting viral spread and might offer new insights for future research on treating viral infections.

Purpose: Heparanase (HPSE) cleaves heparan sulfate proteoglycans during herpes simplex virus-1 (HSV-1) infection, aiding in viral egress and disease progression. Its action has been well established in in vitro and in vivo models, but its relevance in human patients remains unclear. This study aimed to specifically evaluate tear HPSE levels of patients with herpes simplex keratitis (HSK) and to correlate these findings with a commonly used murine model.

Objective: To describe the demographics and clinical profile of Herpes Simplex Virus (HSV) Keratitis in patients presenting to a multi-tier ophthalmology hospital network in South India.

Methods: We have reviewed the medical records of all patients having a clinical diagnosis of any form of HSV keratitis, seen between May 2012 and August 2020 across the L V Prasad Eye Institute network. All the further analyses of the groups were performed using the keywords used for making the diagnosis of HSV keratitis and the data were collected from the electronic medical record system.

Purpose: To evaluate vitreous Galactomannan(GM) and 1,3 β-D-Glucan (BDG) levels in the diagnosis of fungal endophthalmitis, with emphasis on culture-negative cases.

Methods: Vitreous from 31 clinically suspected fungal endophthalmitis patients and 11 controls were evaluated for GM and BDG using ELISA Kits. The Receiver Operating Characteristic (ROC) curves and diagnostic significance was calculated.

Purpose: To determine if retrobulbar injection of hyaluronidase reaches the vitreous cavity, and to determine its concentration in the vitreous.

Methods: Prospective case-control study. Patients undergoing evisceration with implant for noninfective blind eyes were enrolled in the study.

Background: Endophthalmitis is a potentially blinding intraocular infection following intraocular surgery or trauma. Prompt diagnosis and treatment are important in preventing devastating visual complications. Procalcitonin (PCT) is a promising biomarker for diagnosing bacterial infections.
