Purpose: This study aimed to investigate demographic features, diagnoses of uveitis (intraocular inflammation), and real-world clinical practice in the use of local and systemic therapies for patients with uveitis in Tokyo, Japan.

Methods: Clinical records of 1,174 consecutive new patients (480 males, 694 females) referred to the Kyorin Eye Center, Kyorin University Hospital between January 2011 and December 2018 were retrospectively reviewed.

Results: Mean age at presentation was 52.

Article Synopsis
  • "Idiopathic" uveitis is common and means no specific diagnosis is found, while sarcoidosis affects multiple organs, including the eyes.
  • Researchers used miRNA microarrays to analyze the serum profiles of patients with diagnosed ocular sarcoidosis and those suspected of having it, finding clear distinctions from healthy controls.
  • The study revealed similarities in miRNA patterns between the two patient groups and identified shared signaling pathways, suggesting they may have a common underlying pathology, which could aid in earlier diagnosis and treatment.

Background: To analyze clinical features, treatment, complications, and visual outcomes of ocular sarcoidosis at a tertiary center in Tokyo.

Methods: Clinical records of 53 patients with ocular sarcoidosis ("definite" or "presumed") presenting between 2013 and 2018 to the Kyorin Eye Center were retrospectively reviewed. Diagnosis was based on the revised criteria of the International Workshop on Ocular Sarcoidosis.

Purpose: To report on the successful treatment of patients with acute Vogt-Koyanagi-Harada (VKH) disease utilizing the antiviral potential of cyclosporine during the COVID-19 pandemic.

Study Design: Case series.

Methods: Clinical records were retrospectively reviewed of 4 patients presenting with new-onset acute VKH disease who elected to receive initial treatment consisting of bilateral sub-Tenon injection of triamcinolone acetonide combined with immediately starting oral cyclosporine without the use of systemic corticosteroids.

Purpose: To investigate pathological changes in blood vessels and meibomian glands (MGs) in the eyelids of sclerodermatous chronic graft-versus-host disease (cGVHD) model mice.

Methods: We used an established major histocompatibility complex compatible, multiple minor histocompatibility antigen-mismatched sclerodermatous cGVHD mouse model. Blood vessels and MGs of eyelids from allogeneic bone marrow transplantation (allo-BMT) recipient mice and syngeneic bone marrow transplantation (syn-BMT) recipient mice were assessed by histopathology, immunohistochemistry and transmission electron microscopy.

Rationale: An idiopathic macular hole that causes substantial reduction in central visual acuity is believed to involve no obvious underlying diseases; thus, it is suspected to form due to the presence of idiopathic tractional forces at the vitreoretinal interface. Importantly, it is effectively treated with pars plana vitrectomy (PPV), which removes the mechanical forces. However, while it is exceedingly rare, a macular hole can develop in eyes after PPV; fresh or postoperative macular holes can close spontaneously without surgical removal of traction.
