PURPOSE: Exosomes derived from human mesenchymal stem cells (hMSCs) cultured under hypoxic conditions contain proteins and growth factors that promote angiogenesis. This study investigated the effect of intravitreal administration of these exosomes on retinal ischemia using a murine model. METHODS: Oxygen-induced retinopathy (OIR) was induced by exposing one-week-old male C57BL/6J mice to 5 days of 75% hyperoxic conditioning, and returning to room air. After hyperoxic conditioning, the right eye of each mouse was injected intravitreally with 1 µl saline or exosomes derived from hMSCs and compared to control mice of the same age raised in room air without OIR injected intravitreally with saline...

Two patients (a 37-year-old man and a 28-year-old woman) who had choroidal neovascular membrane (CNVM) secondary to inactive toxoplasma retinochoroiditis scarring were evaluated. Multimodal imaging including fluorescein angiography, optical coherence tomography (OCT), and OCT angiography (OCTA) was used. CNVM secondary to inactive toxoplasma retinochoroiditis scarring was detected. Representative images of CNVM were demonstrated in the outer retinal layer and choriocapillary layer on OCTA. OCTA, a relatively new technique, is useful in the diagnosis of the CNVMs secondary to retinochoroiditis...

The authors present the case of a 59-year-old woman in treatment with interferon alfa-2b for stage IV melanoma and widespread metastases who presented with interferon-associated retinopathy. An ocular examination revealed multiple retinal cotton-wool spots and hard exudates. Interferon treatment was suspended. The patient was followed up for 5 months following the baseline visit by means of en face optical coherence tomography (OCT), spectral-domain OCT, and OCT angiography. Multimodal imaging was useful in the follow-up of this condition, permitting the characterization of all the lesions hallmarking the interferon-retinopathy and showing that this illness was related to a reduction of the retinal vascular perfusion...

REVIEW
Rui Hua, Hailin Wang
Optical coherence tomography angiography (OCTA) based on mathematical processing of sequentially acquired structural OCT images has been applied widely in both retinal and choroidal research and may have advantages over traditional angiography. Images obtained by OCTA are rendered under the assumption that the only moving entity in the retina is blood flow. Optical phenomena and image processing algorithms may create imaging artefacts. Therefore, OCTA images require careful interpretation. This review discusses the dark signals seen in the choroidal vasculature on OCTA using multiple factor analysis...
