Limbal stem cells in the eye have the capacity to re-generate Scientists have developed a new technique to regrow human corneas. Using key tracer molecules, researchers have been able to hunt down elusive cells in the eye capable of regeneration and repair. They transplanted these regenerative stem cells into mice – creating fully functioning corneas. […]

SD-OCT shows significant improvement in vision and fluid with a decrease in subretinal fluid heights. With continued treatment, the OCT demonstrates complete resolution of CME with a […]
by Vanessa Caceres EyeWorld Contributing Writer Meta-analysis leaves room for further research A recently published study reported that postmenopausal hormone use might have a protective role in the formation of cataracts.1 However, ophthalmologists who reviewed the analysis cautioned that it is not the definitive word on the topic. The meta-analysis was led by Kairan Lai of […]
Thursday 17 April 2014 – 2am PST Each year in the UK, bacterial infections cause around 6,000 cases of a severe eye condition known as microbial keratitis – an inflammation and ulceration of the cornea that can lead to loss of vision.
