A systematic review of OCT and OCT angiography in retinal vasculitis
Journal of Ophthalmic Inflammation and Infection, 2023 Background Retinal vasculitis is a component of uveitis for which the Standardisation of Uveitis Nomenclature (SUN) working group has no standard diagnostic criteria or severity grading. Fluorescein angiography is the gold standard test to assess retinal

Ultra-Widefield OCT Angiography
IEEE Transactions on Medical Imaging, 2023 Optical Coherence Tomography Angiography (OCTA), a functional extension of OCT, has the potential to replace most invasive fluorescein angiography (FA) exams in ophthalmology. So far, OCTA's field of view is however still lacking behind fluorescence fundus photography techniques.

OCT angiography in the monitoring of vaginal health
APL Bioengineering, 2023 Fractional-pixel CO2 laser therapy shows promise for treating the genitourinary syndrome of menopause (GSM). Nevertheless, it remains controversial in the field of female pelvic medicine. This is due to the inherent difficulties in obtaining noninvasive biopsies to evaluate the treatment's efficacy and safety objectively.
