Article Synopsis
  • Indolent nonprogressive multifocal choroidal lesions are benign growths in the eye that don’t impact visual function, but their effects on retinal circulation and function were previously unclear.
  • A 45-year-old male patient was studied, exhibiting multiple well-defined lesions seen through optical coherence tomography (OCT), which revealed no blood flow within the lesions and reduced circulation above them.
  • Testing showed that, despite some retinal pigment epithelial damage, overall retinal function remained normal, suggesting that while these lesions don't harm vision, monitoring retinal health is important.

3-(4-hydroxy-3-methoxyphenyl) propionic acid (HMPA) is a metabolite produced by the gut microbiota through the conversion of 4-hydroxy-3-methoxycinnamic acid (HMCA), which is a widely distributed hydroxycinnamic acid-derived metabolite found abundantly in plants. Several beneficial effects of HMPA have been suggested, such as antidiabetic properties, anticancer activities, and cognitive function improvement, in animal models and human studies. However, the intricate molecular mechanisms underlying the bioaccessibility and bioavailability profile following HMPA intake and the substantial modulation of metabolic homeostasis by HMPA require further elucidation.

3-(4-hydroxy-3-methoxyphenyl)propionic acid (HMPA) is one of the end-products from gut microbiota from dietary polyphenols, which might contribute to their health benefits. This study aims to investigate the absorption, metabolism, and tissue accumulation of HMPA in Sprague-Dawley (SD) rats. After HMPA (10 mg/kg body weight) was orally administered, intact and conjugated HMPAs in the bloodstream were detected and reached the maximum concentration in 15 min (HMPA, 2.

Article Synopsis
  • The study aimed to evaluate how well amphotericin B (AMPH-B) penetrates the eyes after intravenous administration of liposomal amphotericin B (L-AMB) in patients with fungal eye infections.
  • Seven eyes from five patients were treated with varying doses of L-AMB, and samples were taken from various eye fluids and blood to measure AMPH-B levels.
  • Results showed high concentrations of AMPH-B in the cornea of the keratitis case, but much lower levels were found in the aqueous and vitreous humors, suggesting that L-AMB may only be effective for mild cases of fungal endophthalmitis.

4-Hydroxy-3-methoxycinnamic acid (HMCA), a hydroxycinnamic acid derivative, is abundant in fruits and vegetables, including oranges, carrots, rice bran, and coffee beans. Several beneficial effects of HMCA have been reported, including improvement of metabolic abnormalities in animal models and human studies. However, its mitigating effects on high-fat diet (HFD)-induced obesity, and the mechanism underlying these effects, remain to be elucidated.

Purpose: To determine the relationship between the different isoforms of apolipoprotein E (ApoE) and retinal neovascularization.

Methods: The concentrations of ApoE and VEGF in vitreous humor samples with either a macular hole (MH), or diabetic macular edema (DME), or proliferative diabetic retinopathy (PDR) with or without intravitreal injection of bevacizumab (IVB) were measured by ELISA. The effects of each isoform of ApoE on human retinal microvascular endothelial cells (HRMECs) in culture or on the retina of oxygen-induced retinopathy (OIR) mice were investigated.

Purpose: To describe the clinical manifestations and prognoses in 7 patients with invasive sino-orbital aspergillosis (ISOA).

Methods: This was a retrospective study of consecutive patients who were diagnosed as having ISOA at the Gifu University Hospital and Gifu Municipal Hospital between January 1993 and December 2015. Data were collected on demographics, initial manifestations, examination findings, treatments, clinical course, and outcomes.

Familial amyloid polyneuropathy (FAP) is a systemic disorder transmitted as an autosomal dominant trait and is characterized by deposits of protein fibrils in various organs leading to physiologic dysfunction. In cases with FAP in Japanese endemic foci, their signs and symptoms often develop before the age of 40 years. We report on two elderly patients (an 80-year-old woman and an 83-year-old man) with progressive vitreous opacities (VOs) as the initial manifestation of hereditary transthyretin (ATTR Val30Met) carries, who had no evidence of systemic involvement or family history of amyloidosis and lived in non-endemic areas.

Background: To determine the clinical features, fungal profiles, treatment outcomes, and factors that are significantly associated with the visual outcomes of eyes with endogenous fungal endophthalmitis (EFE).

Material And Methods: The medical records of 17 eyes of 9 patients diagnosed with EFE during January 2005 to December 2013 were reviewed. The collected data included patient characteristics, visual acuities (VAs), length between appearance of the first sign of infection and the first ophthalmic examinations, fungal profiles, and treatment regimen.

We report our findings in a 63-year-old male who developed late-onset bleb-related endophthalmitis. The patient had undergone glaucoma surgery 46 years earlier, and had a thin-walled cystic bleb prior to the endophthalmitis in his right eye. He underwent immediate vitrectomy with intravitreal injections of ceftazidime and vancomycin.

Eight eyes of 7 patients with fungal disease received intravenous injections of 150 to 300 mg micafungin, and samples of blood, cornea, retina-choroid, aqueous humor, and vitreous humor were collected. The micafungin levels in all collected samples exceeded the MICs; however, the levels in the vitreous and aqueous humors were lower. Our findings suggest that intravenous micafungin should be given in combination with intravitreal antifungal agents after vitrectomy in severe cases of intraocular fungal diseases.
