[Characteristics of Spatial and Temporal Variations of Multi-year Vegetation Cover in Different Climatic Zones of China and Their Topographic Effects].

Exploring the spatial and temporal dynamics of vegetation cover in different regions of China and its topographic effect is crucial for maintaining the ecological environment and preventing soil erosion. Based on the MODIS NDVI data from 2000 to 2023, the vegetation cover of China for 24 years was calculated by using the pixel binary model. The spatial and temporal trends of vegetation cover in different regions of China and the influence of topographic factors on the spatial distribution of vegetation cover were investigated by dividing the study area into seven typical climate zones.

Chinese Guideline on the Management of Polypoidal Choroidal Vasculopathy (2022).

Background In mainland China, patients with neovascular age-related macular degeneration (nAMD) have approximately an 40% prevalence of polypoidal choroidal vasculopathy (PCV). This disease leads to recurrent retinal pigment epithelium detachment (PED), extensive subretinal or vitreous hemorrhages, and severe vision loss. China has introduced various treatment modalities in the past years and gained comprehensive experience in treating PCV.

Methods: Major literature databases were searched for studies relevant to myopia in children. All studies used swept-source optical coherence tomography (SS-OCT) or enhanced depth imaging optical coherence tomography (EDI-OCT) to measure the ChT value.

Thin Central Corneal Thickness May Be a Risk Factor for Myopia Progression in Children.

Purpose: This study investigated the correlation between corneal biomechanical parameters and the speed of myopia progression.

Methods: This is a retrospective, multicenter study. Both Chinese and Caucasian children were involved.

Systemic combined with intravitreal methotrexate for relentless placoid chorioretinitis: A case report.

Background: We describe a case of relentless placoid chorioretinitis (RPC) that progressed despite administration of peribulbar and systemic corticosteroids, and was resolved by systemic combined with intravitreal methotrexate.

Case Summary: A 16-year-old male reported painless blurred vision and a temporal scotoma in his right eye for one week. Due to widespread distribution and continuous enlargement, multimodal imaging of the lesions led to the diagnosis of RPC.
