Multidrug-resistant (MDR) bacteria and their associated biofilms are major causative factors in eye infections, often resulting in blindness and presenting considerable global health challenges. Presently, mechano-bactericidal systems, which combine distinct topological geometries with mechanical forces to physically induce bacterial apoptosis, show promising potential. However, the physical interaction process between current mechano-bactericidal systems and bacteria is generally based on passive diffusion or Brownian motion and lacks the force required for biofilm penetration; thus, featuring low antibacterial efficacy.

For the past 50 years, significant progress has been made in understanding Seasonal Hyperacute Panuveitis (SHAPU), a mysterious blinding disease first reported in Nepal in 1975. Predominantly affecting Nepalese children, SHAPU occurs cyclically every odd year from September to December. While initially misclassified as endophthalmitis, SHAPU is set apart by its lack of trauma or surgery, failure to grow organisms in most intraocular fluid cultures, and its hallmark presentation of a "white pupil in red eye" with an association with moth exposure.

Objectives: This study compares the cosmetic and functional outcomes of corneal tattooing/keratopigmentation and ocular prostheses in rehabilitating disfigured eyes, focusing on esthetic appearance and emotional well-being.
Methods: Ninety-two patients were included: 48 received corneal tattooing, and 44 were fitted with ocular prostheses. Anophthalmic surgery was indicated for trauma, painful blind eye, endophthalmitis, tumor, and corneal ulcer, while corneal tattooing was performed for trauma, corneal ulcer, and endophthalmitis.
Introduction Cataracts are the leading cause of blindness worldwide, with a notably high incidence rate. Endophthalmitis is the most severe complication following cataract surgery , often resulting in profound vision loss. This study evaluates the impact of risk factors such as age, sex, diabetes mellitus (DM), hypertension, posterior capsule rupture (PCR), type of surgery, and use of intraocular lens (IOL) material on the risk of endophthalmitis after cataract surgery.

Endophthalmitis is an intraocular microbial infection that can lead to permanent blindness, even with prompt anti-microbial therapy. Multi-drug-resistant organisms are on the rise, potentially limiting the efficacy of current empiric antibiotic therapies of intravitreal ceftazidime and vancomycin. Cefiderocol is a recent FDA- and EMA-approved antibiotic for multi-drug-resistant Gram-negative bacteria.
