Objective: To compare the macular area parameters and aqueous humor factors between myopia and emmetropia.
Methods: Convenience sampling was used to select patients who visited the Changzhi Aier Eye Hospital's department of ophthalmology from December 2018 to December 2022 as the study participants. They were divided into three groups according to whether they were diagnosed as mild myopia myopic, highly myopic or not as follows: the mild myopia group (60 cases, 108 eyes), the high myopia group (46 cases, 78 eyes) and the healthy emmetropia group (40 cases, 65 eyes).
Background: To evaluate retinal structural and functional changes after silicone oil (SO) removal in eyes with macula-off rhegmatogenous retinal detachment (RRD).
Methods: Best-corrected visual acuity (BCVA) testing, microperimetry, and optical coherence tomography angiography were performed in 48 eyes with macula-off RRD before and 3 months after SO removal. The values of healthy contralateral eyes were used as control data.
Gene therapy, a significantly crucial strategy for treatment of malignancies, has been gradually accepted in recent years. However, this therapeutic approach has being facing great challenges concerning problems which include complicated development of cancer with multiple gene control, effective target shortage, low efficiency of gene transferring and safety of the vector delivery system. Shepherdin, a novel peptidomimetic molecule designed from Lys-79 to Leu-87 of survivin, has been identified as a tumor suppressor with the function that can not only competitively interfere with the interaction between survivin and Hsp90 (heat shock protein-90) leading to the degradation of survivin to anti-tumor, but also competitively target the ATP-dependent binding pocket of Hsp90 resulting in the dysfunction of Hsp90 chaperone to cell apoptosis via a mitochondrial dependent or independent pathway.
