Alternative topical ocular antiseptic lowers bacterial load with less pain
[ad_1] Reviewed by Thomas W. Hejkal, MD, PhD Because many people are very sensitive to povidone-iodine 5% (Betadine; Alcon), Thomas Hejkal, MD, PhD, and colleagues set out to identify an alternative ocular antiseptic with the potential to cause fewer ocular problems for their patients that is also as effective at eradicating surface bacteria. Hejkal is…
Read MoreGene therapy for completely colorblind children partly restores cone function
[ad_1] Gene therapy has partly restored the function of the retina’s cone receptors in two children who were born completely colorblind, reports a new study led by UCL researchers. The findings, published in Brain,1 provide hope that the treatment is effectively activating previously dormant communication pathways between the retina and the brain, drawing on the plastic…
Read MoreCaffeine metabolite may slow progression of myopia in children
[ad_1] The progression of myopia in children may be slowed by a metabolite of caffeine, known as 7-MX, according to observational research published online in the British Journal of Ophthalmology.1 If proved safe and effective in large clinical trials, 7-MX could become a valuable treatment for a condition for which current options are somewhat limited, say…
Read MoreMoving past the eyes and into the brain
[ad_1] Reviewed by Lotfi Merabet, OD, PhD, MPH, and Jessie Cronan Cortical/cerebral visual impairment (CVI), a condition related to brain injury, is visual impairment resulting from damage to the visual pathways in the brain. Unfortunately, CVI is all too common although not frequently diagnosed. And therein lies the problem. CVI is the leading cause of…
Read MoreScreen and treat unstable tear film in weeks
[ad_1] Patient expectations for cataract surgery are very high, especially when it comes to advanced-technology implants. To meet those expectations, we need accurate preoperative measurements as a basis for intraocular lens calculations, and we can’t have accurate measurements without a stable tear film. Objective tests such as tear osmolarity and matrix metalloproteinase 9 (MMP-9) offer…
Read MoreCryopreserved amniotic membrane an option treatment of mechanical dry eye
[ad_1] Characterized by loose, redundant conjunctival folds, conjunctivochalasis (CCH), also known as mechanical dry eye (MDE), is a chronic condition that typically affects both eyes and is a common cause of ocular irritation and discomfort.1,2 CCH is associated with various ocular and non-ocular conditions, but it is often overlooked and underdiagnosed in clinical practice as…
Read MoreAPOE gene linked to Alzheimer’s may prevent retinal ganglion cell death
[ad_1] Research led by scientists at Mass Eye and Ear and Brigham and Women’s Hospital, member hospitals of Mass General Brigham, uncovers the role that a genetic variant linked with Alzheimer’s disease, APOE4, plays in protecting against glaucoma. According to a news release from Mass Ear and Eye, in the study published August 16 in…
Read MoreRetina may provide clues to the severity of multiple sclerosis
[ad_1] Assessing the severity of multiple sclerosis (MS) is key as physicians seek a course of treatment for patients diagnosed with this disease, but it can prove to be challenging with existing methods. A study by a team at the Medical University of Vienna is highlighting how the retina can be used as a prognostic…
Read MoreBenefits Of Laser Eye Surgery
Laser assisted in-situ keratomileusis, better known by its initials, LASIK, is a popular eye procedure that permanently corrects deformations of your corneas to allow you to see clearly. To check whether you will benefit from LASIK laser-assisted in-situ keratomileusis surgery to correct your presbyopia, try wearing only a single contact lens, known as monovision. Lasik…
Read MoreWhat Is Photorefractive Keratectomy (PRK)?
Photorefractive Keratectomy (PRK) is a form of eye surgery used to correct eye refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. PRK, sometimes also called superficial LASIK, is the original form of laser eye surgery. PRK is a type of laser eye surgery, similar to LASIK, that treats vision problems by changing the…
