Is It Possible to Use Stem Cell Treatment for Eyes to Restore Vision?

The cornea is a transparent structure at the front of the eye and is mainly responsible for focusing of incoming light rays on the retina for clear vision. The health of cornea is maintained by stem cells present at the junction of cornea and sclera (the white part of the eye) called as limbus. If the limbal stem cells themselves are damaged, the healing of corneal tissue becomes impaired. Scientists at University of Georgia’s Regenerative [...]

Retinitis Pigmentosa Treatment or Cure Possible?

In degenerative conditions like retinitis pigmentosa, the cells (mainly rods) which absorb light and convert the light energy into electrical energy gradually die. The resultant loss of vision is irreversible. For now, there is no treatment available for retinitis pigmentosa. Scientist all over the world are working on solutions to enhance vision and prevent blindness in such cases. There seems to be a breakthrough in retinitis pigmentosa research now. Guglielmo Lanzani and colleagues of the [...]

Topical Anesthetics Can Be Used for Corneal Abrasions

Traditionally, anesthetic eye drops are not used to treat pain caused by corneal abrasion. The topical anesthetics like paracaine and proparacaine when instilled after a corneal abrasion provides relief from pain immediately but it is not prescribed for further use to prevent some possible complications. A review of some recent studies suggests that it may not be true. Via The dogma: Patients with corneal abrasions should not be discharged home with topical anesthetic agents because [...]

Can Zika Virus Cause Blindness?

Zika virus is known for causing congenital abnormalities especially microcephaly in babies born to mothers who were infected with Zika Virus during pregnancy. The virus affects the eyes also. Some ocular manifestations are uveitis, chorioretinal atrophy, intraretinal hemorrhages, optic neuritis, iris colobomas and lens subluxation. Because of the variety of ocular tissues damaged by Zika virus, there are significant chances of the newborn becoming blind. Researchers at Wayne State University School of Medicine Department of Ophthalmology at the [...]

Multi-Pronged Approach to Treat Blindness Considered As Incurable

This is not science fiction. The future is closer than we think. Dr. José-Alain Sahel, chairman of Pitt’s Department of Ophthalmology and director of UPMC Eye Center plans to treat blindness caused by diseases such as glaucoma, retinitis pigmentosa and age-related macular degeneration by his research centred around three approaches: 1. Cameras and processors which convert light energy into impulses which can be perceived by the brain. 2. Genetic therapies which enhance sensing and processing [...]

Eye Test to Detect Memory Problems and Dementia Early

The results of a research done at Moorefields Eye Hospital in London was presented recently at Alzheimer’s Association International Conference (AAIC) 2016 in Toronto. The researchers have found a correlation between the thickness of the retinal nerve fiber layer with some measurable cognitive abilities. This makes sense because retina is an extension of the central nervous system and the changes in the nerve fibres of retina can give a clue about the health of the [...]

How Obstructive Sleep Apnea Causes Glaucoma

Scientists at Hokkaido University have found out how ‘Obstructive Sleep Apnea Syndrome’ (OSAS) causes glaucoma. OSAS is a condition in which the person’s breathing stops during sleep for a significant period of time because of upper airway obstruction. Glaucoma is a condition in which optic nerve is damaged irreversibly leading to visual field defects and later serious vision loss. High intraocular pressure is a risk factor for development of glaucoma. In the study, scientists measured [...]

How to Prevent or Slow Down the Progression of Childhood Myopia or Short-sightedness

Myopia is a condition in which a person cannot see distant objects clearly. In children, it is caused by focusing on near objects like books and electronic devices for long periods. Prolonged near work causes the spasm of the focusing muscle or ciliary muscle in the eye. This is also associated with irreversible elongation of the eye and hence myopia. Myopia cannot be reversed or cured. But there are some steps which parents can take [...]

Study Says the Blue Light Does Not Damage the Eyes

Some studies have shown previously that exposure to LED (light emitting diode) light, especially the shorter wavelength of white light (blue light) can cause damage to the retina induced by oxidative stress. The other sources which emit blue light are computers, tablets, television screens and mobile phones. LED lights as well as the use of digital devices has increased in the last few years and its use is likely to be much more in the [...]

Possible Future of Cataract Surgery – Regenerated Natural Lens

Cataract is one of the most common causes of significant visual loss worldwide. The treatment of cataract is removal of cataract surgically and implantation of an artificial lens to replace the cataractous lens. These lenses are called intraocular lens (IOL) and are either rigid or foldable depending on the size of the incision through which cataract is removed and the technique used for the surgery. The intraocular lens helps the patient see clearly after cataract [...]
