Dissecting the angiogenic mechanism of pachychoroid polypoidal choroidal vasculopathy

iMeta, Volume 5, Issue 5, October 2026.
A prognosis‐oriented classification system was established to distinguish Pachy PCV from Non‐pachy PCV using a large multicenter dataset. Comparative plasma multi‐omics profiling of Pachy PCV, Non‐pachy PCV, and normal controls revealed unique upregulation of the fluid shear stress and atherosclerosis (FSS‐AS) and HIF‐1 signaling pathways in Pachy PCV.

Processionary Moth Exposure in Europe: Toxic–Irritant and Immunoglobulin E‐Mediated Endotypes, Diagnosis and Management

Clinical &Experimental Allergy, Volume 56, Issue 9, Page 1017-1030, September 2026.
Most reactions are toxic–irritant, driven by epithelial injury and neuro‐inflammatory activation. IgE‐mediated allergy is less common but may cause immediate systemic reactions. Endotype differentiation guides diagnosis, risk stratification and management.

Biopsy of Iris and Anterior Chamber Tumours: Fine Needle, Minimally Invasive and Excision Techniques ‐ Review

Clinical &Experimental Ophthalmology, Volume 54, Issue 7, Page 955-973, September/October 2026.
ABSTRACT Several benign, inflammatory and malignant lesions can present as iris or anterior chamber masses, including iris naevi, cysts, adenomas, leiomyomas, nodules, vascular tumours, melanomas, metastases, as well as iris and pigment epithelium adenocarcinomas. Fortunately, benign iris lesions are much more common than malignant tumours and many can

CRB1 ‐Associated Inherited Retinal Dystrophies: Prospective Natural History Study With 4 Years of Follow‐Up

Clinical &Experimental Ophthalmology, Volume 54, Issue 7, Page 917-931, September/October 2026.
ABSTRACT Background The lack of validated and sensitive clinical endpoints remains a major challenge in the design of gene therapy trials for inherited retinal dystrophies (IRDs). This prospective longitudinal cohort study describes the natural disease progression of IRDs caused by pathogenic mutations in the Crumbs homologue 1 (CRB1) gene, and ...
