Stem cell treatment for glaucoma

Glaucoma is an eye disorder in which the optic nerve suffers damage, permanently damaging vision in the affected eye(s) and progressing to complete blindness if untreated. It is often, but not always, associated with increased pressure of the fluid in the eye (aqueous humour). The term 'ocular hypertension' is used for cases having constantly raised intraocular pressure (IOP) without any associated optic nerve damage. Conversely, the term 'normal' or 'low tension glaucoma' is suggested for the typical visual field defects when associated with a normal or low IOP.

The nerve damage involves loss of retinal ganglion cells in a characteristic pattern. There are many different subtypes of glaucoma, but they can all be considered a type of optic neuropathy. Raised intraocular pressure is a significant risk factor for developing glaucoma. One person may develop nerve damage at a relatively low pressure, while another person may have high eye pressure for years and yet never develop damage. Untreated glaucoma leads to permanent damage of the optic nerve and resultant visual field loss, which can progress to blindness.

Glaucoma can be divided roughly into two main categories

  • open angle: Open angle, chronic glaucoma tends to progress at a slower rate and patients may not notice they have lost vision until the disease has progressed significantly.
  • closed angle: Closed angle glaucoma can appear suddenly and is often painful; visual loss can progress quickly, but the discomfort often leads patients to seek medical attention before permanent damage occurs.

Mol Cell Biochem. 2017 Feb 16;: Authors: Minhas G, Prabhakar S, Morishita R, Shimamura M, Bansal R, Anand A Abstract Retinal ischemia is a condition associated with retinal degenerative diseases such as glaucoma, diabetic retinopathy, and other optic neuropathies, leading to visual impairment and blindness worldwide. Currently, there is no therapy available for ischemic retinopathies. Therefore, the aim of this study was to test a murine model of pterygopalatine artery ligation-induced retinal injury for transplantation of mouse bone marrow-derived lineage-negative (lin-ve) stem cells. The mouse external carotid artery and pterygopalatine artery were ligated for 3.5 h followed by reperfusion. The model was validated through fundus fluorescein angiography, laser Doppler and FITC dextran perfusion in whole-mounts. Lin-ve stem cells isolated from mouse bone marrow were transplanted through tail-vein, which showed migration to retina leading to decrease in GFAP expression. The neurotrophic factors such as BDNF and FGF2 showed enhanced expression in the retina. The functional analysis with electroretinogram did not demonstrate any significant changes before or after injury or stem cell transplantation. This study shows a neuroprotective potential in lin-ve stem cells in the retinal ischemia induced by pterygopalatine artery ligation and presents a practical model for validating therapies for ischemic disorders of the retina in future.
