Since the introduction of combination antiretroviral therapy (cART) in Japan in 2008, the spectrum of ocular manifestations in patients with human immunodeficiency virus (HIV) has changed. This study, conducted at Tokyo Medical and Dental University Hospital between January 2012 and August 2023, aimed to understand the epidemiology and clinical features of ocular manifestations in patients with HIV during the cART era. Of the 218 patients diagnosed with HIV, 23 (10.55%) exhibited ocular manifestations; all were male, aged 32–73. The most prevalent ocular complication was uveitis (60.67%). Notably, the prevalence of uveitis in this cART era has surged compared to earlier Japanese studies. Our data also suggest a potential direct link between uveitis and HIV, particularly in patients who have not yet undergone cART. However, cytomegalovirus retinitis, another prevalent ocular disease in our study, appeared more strongly associated with patients who commenced cART. Neither ocular condition was significantly correlated with CD4+ T-cell count. Importantly, our observed ocular manifestation prevalence (10.55%) was lower than that in previous studies, emphasizing the potential influence of cART and national healthcare support. These findings provide unique insights into the evolution of ocular manifestations in patients with HIV in Japan amidst cART availability. [ABSTRACT FROM AUTHOR]

Background. To investigate the vitreous opacity in patients with familial amyloidotic polyneuropathy (FAP) in two major endemic areas, Japan and Sweden. Methods. We obtained clinical data for 90 patients with vitreous opacity that was associated with FAP amyloidogenic transthyretin (ATTR) Val30Met; 18 Japanese patients and 72 Swedish patients. We reviewed medical records at Kumamoto University Hospital in Japan and Umeå University Hospital in Sweden. We evaluated the characteristics of the patients, systemic and ocular histories, clinical findings and treatment. Results. Swedish patients were significantly older at the onset of vitreous opacity (mean age 67.8 years) than were Japanese patients (47.6 years). A similar age difference was found for the onset of polyneuropathy. In addition, Swedish patients without polyneuropathy were significantly older (74.1 years) at the onset of vitreous opacity than those with polyneuropathy (64.6 years). A significant difference in the occurrence of vitreous opacity as the only manifestation of FAP was seen for Swedish patients (35%) compared with Japanese patients (6%). Conclusions. Swedish FAP ATTR Val30Met patients appeared to develop vitreous opacity later and more frequently compared with Japanese patients. [ABSTRACT FROM AUTHOR]
