Abstract:
Apoptosis, or programmed cell death, plays a vital role in normal development and ageing. However, dysregulation of this process is responsible for many disease states including; cancer, autoimmune and neurodegeneration. For this reason, in vivo visualisation of apoptosis may prove a useful tool for both laboratory research and clinical diagnostics. Glaucoma comprises a distinctive group of chronic optic neuropathies, characterised by the progressive loss of retinal ganglion cells (RGCs). Early diagnosis of glaucoma remains a clear and unmet need. Recently, there have been significant advances in the detection of apoptosis in vivo using fluorescent probes to visualise single RGCs undergoing apoptosis, specifically DARC (Detection of Apoptotic Retinal Cells) [1] and capQ technology [2(••)].
