High Levels of C5a Are Associated With Reduced Macular Sensitivity in Patients With Myeloproliferative Neoplasms.

Purpose: Previous findings indicate that patients with myeloproliferative neoplasms (MPN) exhibit elevated levels of inflammatory biomarkers and have a high prevalence of AMD. In this study, we aim to determine whether drusen and systemic inflammation in patients with MPN affect macular sensitivity in the same manner as in patients with AMD.

Methods: The study was conducted as a prospective cross-sectional study.

Intravesical instillation of bacillus Calmette-Guérin (BCG) is used for the maintenance treatment of some types of bladder cancer. Although rare, ocular complications can develop following intravesical BCG treatment. This is a case report of culture-positive Mycobacterium bovis BCG endophthalmitis following intravesical BCG installation.

Serum levels of IL-4, IL-13 and IL-33 in patients with age-related macular degeneration and myeloproliferative neoplasms.

Immune responses play a key role in the pathogenesis and progression of myeloproliferative neoplasms (MPN) and age-related macular degeneration (AMD). Recent studies suggested using MPNs as a "Human Inflammation Model" of drusen development and previous results showed interleukin-4 (IL-4) dysregulation in MPN and AMD. IL-4, IL-13 and IL-33 are all cytokines involved in the type 2 inflammatory response.
