Classification of Non-Infectious and/or Immune Mediated Choroiditis: A Brief Overview of the Essentials.

Diagnostics (Basel) 2021 May 24;11(6). Epub 2021 May 24.

Retinal and Inflammatory Eye Diseases, Centre for Ophthalmic Specialized Care (COS), Clinic Montchoisi Teaching Centre, 1003 Lausanne, Switzerland.

The choroid was poorly accessible to imaging investigation until the last decade of the last century. With the availability of more precise imaging methods such as indocyanine green angiography (ICGA) and, later, optical coherence tomography (OCT), enhanced depth OCT (EDI-OCT), and OCT angiography (OCTA), appraisal of choroidal inflammation has substantially gained in accuracy. This allowed to precisely determine which structures were touched in the different non-infectious choroiditis entities and made it possible to classify this group of diseases, ICGA signs, mainly hypofluorescent lesions, were identified and described.

The P300/XBP1s/Herpud1 axis promotes macrophage M2 polarization and the development of choroidal neovascularization.

J Cell Mol Med 2021 May 31. Epub 2021 May 31.

Department of Ophthalmology, Ningbo Eye Hospital, Ningbo, China.

Neovascular age-related macular degeneration (AMD), which is characterized by choroidal neovascularization (CNV), leads to vision loss. M2 macrophages produce vascular endothelial growth factor (VEGF), which aggravates CNV formation. The histone acetyltransferase p300 enhances the stability of spliced X-box binding protein 1 (XBP1s) and promotes the transcriptional activity of the XBP1s target gene homocysteine inducible endoplasmic reticulum protein with ubiquitin-like domain 1 (Herpud1).

Polypoidal Choroidal Vasculopathy after Stereotactic Radiotherapy for Neovascular Age-Related Macular Degeneration: A Case Report with Long-Term Follow-Up.

Case Rep Ophthalmol 2021 Jan-Apr;12(1):299-305. Epub 2021 Apr 30.

Medical Retina Department, Vista Klinik Binningen, Binningen, Switzerland.

Several adjunct therapies to the gold standard anti-vascular endothelial growth factor (anti-VEGF) intravitreal injections have been discussed for the treatment of neovascular age-related macular degeneration (nAMD). Low-dose stereotactic radiotherapy (SRT) showed the potential to lower the treatment burden by reducing the anti-VEGF treatment frequency at least over 2-3 years but was associated with retinal microvascular abnormalities in a few cases. We report a 6-year follow-up of a case with bilateral nAMD under anti-VEGF treatment which developed multiple polypoid choroidal vasculopathy (PCV) lesions in the eye adjunct treated with low-dose SRT.

University of Hawaii John A. Burns School of Medicine, 651 Ilalo St., Honolulu, HI 96813; Hawaii Macula and Retina Institute, 98-1079 Moanalua Road, Suite 470, Aiea, HI 96701; Retina Consultants of Hawaii, 98-1079 Moanalua Road, Suite 470, Aiea, HI 96701; The Retina Center at Pali Momi, 98-1079 Moanalua Road, Suite 470, Aiea, HI 96701.

Purpose: Although polypoidal choroidal vasculopathy (PCV) is best diagnosed with indocyanine green angiography (ICGA), ICGA is often unavailable or not ordered. Optical coherence tomography (OCT) is widely available, and OCT B-scan can visualize polypoidal lesions diagnostic of PCV as inverted U-shaped elevations of the retinal pigment epithelium (RPE) with heterogeneous reflectivity and sometimes ring-shaped lesions within the polypoidal lesion. This study aims to differentiate findings between eyes diagnosed with PCV or typical exudative age-related macular degeneration (AMD) using ICGA, then comparing findings noted on the OCT B-scan line scan in each group.

UVEAL MELANOMA IN A 15-YEAR-OLD GIRL. CASE REPORT.

Cesk Slov Oftalmol 2021 ;77(2):94-100

Uveal melanoma is the most common intraocular tumour in adults, it is a form of cancer that affects mostly older adults, as the average age at detection of this tumour is 60 years, but it can occur in any age group with no significant gender difference. However, uveal melanoma is very rare in children compared to the adult population, accounting for 1 % of all cases. In pediatric patients, malignant uveal melanoma is more frequently manifested during puberty, leading to speculation of an association between uveal melanoma and growth hormone levels. Read More

Intravitreal injection of anti-miRs against miR-142-3p reduces angiogenesis and microglia activation in a mouse model of laser-induced choroidal neovascularization.

Aging (Albany NY) 2021 05 5;13(9):12359-12377. Epub 2021 May 5.

Department of Cardiology, CARIM School for Cardiovascular Diseases, Faculty of Health, Medicine and Life Sciences, Maastricht University, Maastricht, The Netherlands.

Age-related macular degeneration (AMD) is a worldwide leading cause of blindness affecting individuals over 50 years old. The most aggressive form, wet AMD, is characterized by choroidal neovascularization (CNV) and inflammation involving microglia recruitment. By using a laser-induced CNV mouse model, we provide evidence for a key role played by miR-142-3p during CNV formation. Read More
