Summary: This study evaluated the characteristics, microbiological spectrum, management, and outcomes of patients with culture-proven fungal keratitis. The results showed that infection with filamentous organisms was more common than with yeast, and the most common filamentous organisms were Fusarium and Aspergillus, while the most common yeast was Candida. Contact lens use was the main predisposing factor for filamentous keratitis, while yeast keratitis was most associated with an immunocompromised host and ocular surface disease. Visual outcomes were poor, with nearly half of the eyes remaining at 20/200 or worse upon resolution of infection. Antifungal susceptibility testing influenced treatment in 80% of cases in which it was performed.

Summary: Microbial keratitis, the most common cause of infective vision loss, requires intensive antimicrobial therapy and varies in causative organisms by region. A retrospective review of 160 cases at an Australian tertiary referral hospital found that the most common pathogens were Herpes Simplex, Staphylococcus aureus, and Pseudomonas aeruginosa. The study showed that microbial keratitis imposes a significant economic burden, with a median cost of AUD 8013 (USD 5447) and a total annual cost of AUD 13.58 million (USD 9.23 million) in Australia.

Summary: The purpose of this study was to assess the trends in microorganisms causing infectious keratitis and their antibiotic susceptibility patterns at a tertiary eye care center in India. Retrospective review of microbiological records from 1991 to 2020 revealed a decrease in bacteria and an increase in fungal isolates. Gram-positive bacteria, particularly Streptococcus pneumoniae, showed a rising trend, while Staphylococcus epidermidis decreased over the 30-year period. Pseudomonas aeruginosa was the most prevalent gram-negative pathogen, and Fusarium spp. and Aspergillus spp. were the most common fungal isolates. Resistance to various antibiotics, including fluoroquinolones, showed an increasing trend. The changing spectrum of keratitis and the rising antibiotic resistance emphasize the importance of regular surveillance.

Summary: This study presents a facile synthetic approach to prepare a phthalocyanine-based photosensitizer conjugated with a cyclic bactenecin peptide, which shows selective affinity toward bacteria and synergistic cytotoxic effects against a spectrum of multidrug-resistant bacterial strains. The inhibition mechanism is believed to be based on the physical destruction of the cell membrane due to the cyclic peptide followed by photodynamic action induced by the phthalocyanine unit.

Summary: Retinal drusen are uncommon in IgA nephropathy, but they resemble drusen found in age-related macular degeneration. The IgA-staining deposits in the drusen are likely related to systemic deposition of IgA. The nature of cystic spaces in the drusen is still unknown. Further research on the retinas of people with glomerulonephritis is recommended.

Summary: The study investigated the phenotype, variability, and penetrance of IMPG2-related maculopathy. The results showed that mono-allelic IMPG2 variants could result in haploinsufficiency manifesting as a maculopathy with variable penetrance and expressivity. Family members of patients with IMPG2-related retinitis pigmentosa may also present with vitelliform lesions. The maculopathy is usually limited to the fovea and is associated with moderate visual impairment.
