A rare case of culture-negative infective endocarditis following cataract surgery.
J Int Med Res
January 2025
Colombo South Teaching Hospital, Colombo, Sri Lanka.
A 70-year-old man developed intermittent fever with chills, severe anorexia, generalized weakness, and mild exertional difficulty in breathing following posterior chamber intraocular lens replacement surgery for a mature white cataract in the left eye. Laboratory tests revealed persistent negative blood cultures, normocytic and normochromic anemia, neutrophilia, and elevated inflammatory markers despite multiple courses of antibiotics. All other investigations conducted to identify the cause of prolonged fever, including transthoracic echocardiography, were negative.

Purpose: Bietti crystalline dystrophy (BCD) is a rare retinal dystrophy characterized by progressive visual impairment. This study aimed to evaluate changes in retinal and choroidal vessels and blood flow in BCD patients using swept-source optical coherence tomography angiography (SS-OCTA) and to investigate potential parameters associated with visual function.
Methods: This cross-sectional study included 166 eyes from 86 clinically diagnosed BCD patients, classified into three disease stages based on Yuzawa's classification.
New insights into persistent corneal subepithelial infiltrates following epidemic keratoconjunctivitis: The first case report with ultrastructural and immunohistochemical investigations.
Acta Histochem

Epidemic keratoconjunctivitis (EKC) is one of the most severe clinical manifestations of human adenovirus ocular surface infection, which may lead to the formation of subepithelial infiltrates (SEIs) in the anterior corneal stroma in 20-50 % of cases. SEIs may be asymptomatic or give rise to corneal aberrations and visual impairment for months or years after acute infection, despite treatments. Here, we describe the ultrastructural and immunophenotypic features of the anterior corneal stroma of a patient who underwent superficial anterior lamellar keratoplasty (SALK) surgery to remove corneal opacities related to clinically significant and steroid-unresponsive, long-lasting SEIs after adenoviral EKC.

Eye Contact Lens
January 2025
Medical College of Wisconsin, Milwaukee, WI.
Purpose: To describe a rare case of infectious keratitis secondary to Brevundimonas diminuta, a gram-negative bacillus with fluoroquinolone resistance and rare clinical isolation.
Methods: A 50-year-old man with contact lens overuse presented with a large corneal ulcer and hand motion visual acuity. Initial treatment with fortified topical tobramycin and vancomycin yielded slow improvement, and initial culture grew Staphylococcus epidermidis, Staphylococcus hominis, and Corynebacterium bovis.
Human amniotic membrane graft removal and histopathologic evaluation following closure of a full thickness macular hole.
Am J Ophthalmol Case Rep
March 2025
University of Florida, Department of Ophthalmology, USA.
Purpose: Human amniotic membrane (hAM) grafts have been used to close persistent macular holes in recent years. The results from these surgeries are promising with improved closure rate and vision. However, there is lack of data for what happens to these membranes and how long the tissue should remain inside the patient's eyes.
