Bacteria adherent on the active or inactive surface can form biofilms in which they are encased in a hydrated matrix of extracellular polymeric substances, which is so called bacterial biofilm (BBF). BBF has greater virulence and drug resistance, they can also evade the host immune system and lead to immune injury compared with planktonic bacteria. Many common medical infections involving ophthalmic infection are biofilm-associated. In this paper, the concept and biological characteristics of BBF and BBF-related ophthalmic infection were reviewed.

Objective: Periorbital necrotizing soft tissue infection (NSTI) is a rare entity caused either by polymicrobial infection (type 1) or Streptococcus pyogenes and/or Staphylococcus species (type 2). A high level of clinical suspicion is necessary to make the diagnosis. We present 3 cases of NSTI illustrating our diagnostic and therapeutic approach.

Inherited retinal diseases (IRDs) constitute a heterogeneous group of clinically and genetically diverse conditions, standing as a primary cause of visual impairment among individuals aged 15-45, with an estimated incidence of 1:2000. Our study aimed to comprehensively evaluate the genetic variants underlying IRDs in the Turkish population. This study included 50 unrelated Turkish IRD patients and their families.

A 71-year-old man complained of a blackish wound under his left eye, which began with fever and reddish spots after helping to slaughter a cow and cut its meat. The fever occured especially in the afternoon to evening, and is not accompanied by chills and sweating. On day 4 of fever onset, the fever diminished and the spots progressively widened with swelling.

Introduction: The present study aimed to explore the epidemiologic threats and factors associated with the coronavirus disease 2019 (COVID-19)-associated mucormycosis (CAM) epidemic that emerged in Egypt during the second COVID-19 wave. The study also aimed to explore the diagnostic features and the role of surgical interventions of CAM on the outcome of the disease in a central referral hospital.
Methodology: The study included 64 CAM patients from a referral hospital for CAM and a similar number of matched controls from COVID-19 patients who did not develop CAM.

The Rift Valley fever virus (RVFV) causes haemorrhagic fever, encephalitis, and permanent blindness and has been listed by the WHO as a priority pathogen. To study RVFV pathogenesis and identify small-molecule antivirals, we established a novel In Vivo model using zebrafish larvae. Pericardial injection of RVFV resulted in ~4 log viral RNA copies/larva, which was inhibited by the antiviral 2'-fluoro-2'-deoxycytidine.
