In a clinical trial of 113 patients led by researchers at Imperial College London and UCL, retinal imaging technology called Detection of Apoptosis in Retinal Cells (DARC) was able to identify areas of the eye that were showing signs of geographic atrophy (GA) - a common condition that causes reduced vision and blindness.
People may describe eyelids that sag excessively as droopy. Droopy eyelids can change a person’s appearance or cause problems such as obscured vision.
Engineers and ophthalmologists at Duke University have developed a robotic imaging tool that can automatically detect and scan a patient's eyes for markers of different eye diseases.
Several types of dermatitis can produce eczema around the eyes and on the eyelids. This causes discoloration, itching, and swelling.
Central retinal artery occlusion (CRAO) is a rare but devastating vascular episode that can have severe impact on vision. Treatment is very time-limited and needs to be initiated very quickly to salvage any vision.
Photophobia refers to an increased sensitivity to light, which can result in pain or avoidance. People with the condition feel that normal light is too bright.
Nerve fibre loss and an increase in key immune (dendritic) cells on the surface of the eye (cornea) may be an identifying feature of 'long COVID', suggests a small study published in the British Journal of Ophthalmology.
Stimulation of the nervous system with neurotechnology has opened up new avenues for treating human disorders, such as prosthetic arms and legs that restore the sense of touch in amputees, prosthetic fingertips that provide detailed sensory feedback with varying touch resolution, and intraneural stimulation to help the blind by giving sensations of sight.
Worse visual acuity, contrast sensitivity, and stereo acuity impairment are associated with an increased risk for cognitive decline in older, community-dwelling individuals, according to a study published online July 16
Childhood is a crucial time for developing healthy vision. Symptoms of eye problems in children can sometimes be obvious and other times may be more subtle. It’s important to detect and treat issues early, while vision is still developing. Regular screenings with a pediatric ophthalmologist can help protect your child’s vision as they grow.
