An advance for drug-eluting contact lenses: Delivery to the back of the eye
Drug-eluting contact lenses, which gradually release drugs into the eye, offer a promising alternative to daily eye drops, which can be unpleasant and hard for patients to properly administer. In a 2016 pre-clinical study of glaucoma, the engineered lenses lowered eye pressure at least as well as daily eye drops. New work from Massachusetts Eye ...

Optimized CRISPR/Cas9 gene editing averts hearing loss in ‘Beethoven’ mice
Using a novel gene-editing approach, scientists at Boston Children’s Hospital and Harvard Medical School have salvaged hearing in a mouse model of hereditary deafness, with no apparent off-target effects. The system successfully identified a single misspelled “letter” in the defective copy of a gene required for hearing, disabled this aberrant copy, and spared the healthy ...

Jillian’s story: Finding care, support, then a diagnosis
Eighteen-year-old Jillian Allair is funny, independent, sarcastic, and the charmer of the family. She loves music, especially top 40, and little kids, with a soft spot for those with medical challenges. Jillian knows a thing or two about medical challenges herself — she’s been a patient at Boston Children’s Hospital since she was 8 weeks ...

Tracking the elusive genes that cause strabismus
Strabismus is a common condition in which the eyes do not align properly, turning inward, outward, upward or downward. Two to four percent of children have some form of it. Some cases can be treated with glasses or eye patching; other cases require eye muscle surgery. But the treatments don’t address the root causes of strabismus, which ...

Drug-eluting contact lens offers hope in glaucoma
Daily medicated eye drops are the first line of treatment for glaucoma, the leading cause of irreversible blindness. The drops relieve pressure in the eye, a significant risk factor for glaucoma. But they’re not ideal: their delivery is imprecise, they can cause stinging and burning and patients often struggle to administer them. Adherence is poor: ...

Drug ‘cocktail’ could restore vision in optic nerve injury
When Zhigang He, PhD, started a lab at Boston Children’s Hospital 15 years ago, he hoped to find a way to regenerate nerve fibers in people with spinal cord injury. As a proxy, he studied optic nerve injury, which causes blindness in glaucoma — a condition affecting more than four million Americans — and sometimes ...

BabySee: Mobile app lets you see through an infant’s eyes
David Hunter, MD, PhD, chief of Ophthalmology at Boston Children’s Hospital, gets a lot of questions from parents, but the number one question is: “What can my baby see?” That depends. How old is the baby? Five days after birth, she might see something like the image at left; at 3 months, the image at ... Read More about BabySee: Mobile app lets you see through an infant’s eyes
The neurology resident that could
Elizabeth Engle used to wait in peoples’ driveways until midnight, hoping to enroll them in her genetic studies of eye-movement disorders. She landed there by chance: during her neurology residency, she saw a little boy whose eyes were frozen in a downward gaze. Wanting to find a solution to a disorder that others had written ...
