Background: Ca entry plays an important role in modulating endothelial cell migration and tube formation. Transient receptor potential cation channel subfamily V member 4 (TRPV4) is a Ca-permeable channel that is widely expressed in endothelial cells. It has been reported that TRPV4 is expressed in HRCECs and regulates Ca entry.

Methods: Seventy-five 1-week-old guinea pigs were randomly divided into normal control, form deprivation myopia (FDM), and self-control groups. FDM was induced for different times using coverage with translucent latex balloons and FDM recovery was performed for 1wk after 4wk treatment; then, changes in refractive power and axial length were measured.
Aim: To comprehensively analyze the risk factors of rhegmatogenous retinal detachment (RRD) associated with choroidal detachment (CD).
Methods: A total of 265 eyes of 265 consecutive cases of RRD were retrospectively analyzed. All patients had systemic and ophthalmologic examination.
Aim: To observe the changes of vitreous cavity length and diopter after scleral encircling (SE) produce.
Methods: This prospective study included 68 eyes of 68 non-consecutive patients with macula-off retinal detachment who were operated by SE surgery. The corneal refractive power, ocular axial length and diopter were measured by keratometer, A-mode ultrasonic meter and computed dioptometer.
Aim: To investigate whether photoreceptor necroptosis induced by z-VAD-FMK (pan caspase inhibitor) was involved the activation of autophagy and whether Necrostatin-1, a specific necroptosis inhibitor, could inhibit this induction of autophagy after experimental retinal detachment.
Methods: Experimental retinal detachment models were created in Sprague-Dawley rats by subretinal injection of sodium hyaluronate and subretinal injections of z-VAD-FMK, vehicle or z-VAD-FMK plus Necrostatin-1. Three days after retinal detachment, morphologic changes were observed by transmission electron microscopy.
Objective: To explore the effect of Blocking activation of IGF-1-Stat3 signaling pathway in guinea pig sclera fibroblast (GSFs) by AG490 on expressions of MMP-2, Integrinβ(1).
Methods: Cultured GSFs were divided into four groups: group A(control group: only DMEM without IGF-1), group B (only IGF-1 group), group C(IGF-1 + PBS group), group D (IGF-1 + 25 µmol/L AG490 group). The expressions of Stat3, p-Stat3, MMP-2, Integrinβ(1) protein induced by IGF-1 and inhibited by AG490 in GSFs were detected by Western blot.
Objective: To assess the clinical effects of supracapsular implantation with optic capture of the posterior chamber intraocular lens in school-age children with traumatic cataract.
Method: It was a retrospective case series study. Thirteen cases (13 eyes) received posterior curvilinear capsulorhexis with optic capture of the posterior chamber intraocular lens.
