Central and Peripheral Changes in Retinal Vein Occlusion and Fellow Eyes in Ultra-Widefield Optical Coherence Tomography Angiography.

Purpose: To explore the central and peripheral retinal and choroidal changes in retinal vein occlusion (RVO) and fellow eyes using ultra-widefield swept-source optical coherence tomography angiography (UWF-SS-OCTA).

Methods: Fifteen ischemic central RVO (CRVO), 15 branch RVO (BRVO), and 15 age-matched healthy controls were prospectively recruited. Retinal and choroidal parameters, including retinal vessel flow density (VFD) and vessel linear density (VLD), choroidal vascularity volume (CVV), choroidal vascularity index (CVI), and VFD in the large and medium choroidal vessels (LMCV-VFD), were measured in the central and peripheral regions of the 24 × 20-mm UWF-SS-OCTA images.

The incidence, risk factors, management and prognosis of postoperative systemic complications after ophthalmic surgery: a retrospective study at a tertiary, academic referral hospital over a decade.

Purpose: To explore the incidence, risk factors, management and prognosis of systemic complications after ophthalmic surgeries.

Methods: A retrospective review of hospitalized patients undergoing ophthalmic surgeries between 2012 and 2022 at Peking Union Medical College Hospital was performed to summarize and analyse the postoperative systemic complications. Multivariate logistic and linear regression analyses were conducted to clarify the risk factors of postoperative systemic complications and factors associated with the severity of adverse events.
