- Human brain organoids respond to visual stimuli when transplanted into adult ratson February 2, 2023 at 4:26 pm
Researchers show that brain organoids — clumps of lab-grown neurons — can integrate with rat brains and respond to visual stimulation like flashing lights.
- Contact lenses to treat dry eye syndromeon January 30, 2023 at 4:24 pm
Engineers have developed a contact lens prototype that is specially designed to prevent contact lens-induced dry eye (CLIDE). The lens alleviates this condition by facilitating tear flow in response to normal eye blinking. This can relieve the discomfort, visual impairment, and risk of inflammation experienced by millions of CLIDE sufferers.
- Why episodes of low blood sugar worsen eye disease in people with diabeteson January 26, 2023 at 2:55 pm
People with diabetes who experience periods of low blood sugar — a common occurrence in those new to blood sugar management — are more likely to have worsening diabetic eye disease. Now, researchers say they have linked such low blood sugar levels with a molecular pathway that is turned on in oxygen-starved cells in the eye.
- Research challenges ‘sugar hypothesis’ of diabetic cataract developmenton January 25, 2023 at 5:16 pm
New findings contradict previous notions about sugar’s role in the onset of diabetic cataracts. Using an animal model that more closely recapitulates type 2 diabetes in humans, the research team found early signs of damage in the eye before the onset of type 2 diabetes, suggesting that diabetic complications may start during the pre-diabetic state.
- Neuroscientists identify a small molecule that restores visual function after optic nerve injuryon January 20, 2023 at 2:31 pm
Traumatic injury to the brain, spinal cord and optic nerve in the central nervous system (CNS) are the leading cause of disability and the second leading cause of death worldwide. CNS injuries often result in a catastrophic loss of sensory, motor and visual functions, which is the most challenging problem faced by clinicians and research scientists. Neuroscientists have recently identified and demonstrated a small molecule that can effectively stimulate nerve regeneration and restore visual functions after optic nerve injury, offering great hope for patients with optic nerve injury, such as glaucoma-related vision loss.

- Greater risk of cystoid macular edema may exist after DMEK compared to DSAEKon February 3, 2023 at 9:08 pm
Descemet membrane endothelial keratoplasty (DMEK) correlates with greater cystoid macular edema risk compared to Descemet stripping automated endothelial keratoplasty (DSAEK).
- Week in review: Endophthalmitis outbreak, hypoglycemia worsens diabetic retinopathy, pediatric ophthalmologist shortageon February 2, 2023 at 9:07 pm
A fungal endophthalmitis outbreak is reported in South Korea, researchers study how low blood sugar worsens diabetic eye disease, and many counties in the United States lack pediatric ophthalmologists.
- Early diagnosis and treatment of histiocytic disorders are essentialon February 2, 2023 at 5:06 pm
A case series looked at the clinical features of histiocytic disorders with orbital, ocular, optic nerve, and cavernous sinus involvement, as well as patient outcomes.
- Pediatric vision screening visits in the United States declined from 2016 to 2020on February 1, 2023 at 6:22 pm
A recent report, originally presented at the AAO 2022 Annual Meeting, focused on trends in pediatric vision screening in the United States from before the COVID-19 pandemic through the first year of the pandemic.
- Even after spontaneous regression of ROP, retinal problems persiston January 31, 2023 at 10:30 pm
A retrospective study evaluated residual characteristics of spontaneously regressing retinopathy of prematurity seen at the end of acute-phase retinal screening examinations.
