| |  | | |  A healthy eye pressure should be between 10 mm Hg and 21 mm Hg. Eye pressure measurements that are consistently above the upper limit are considered indicative of ocular hypertension. | | | | |  As Age-Related Macular Degeneration/Low Vision Awareness Month comes to a close, we’re sharing three stories by Bonnielin Swenor, Ph.D., M.P.H., assistant professor of ophthalmology at the Wilmer Eye Institute in the Johns Hopkins University School of Medicine, and an assistant professor of epidemiology at the Johns Hopkins Bloomberg School of Public Health. | | | | |  Nyctalopia is the name for a symptom characterized by the reduced ability to see at night and in low light conditions. It is also called night-blindness. While it isn’t a medical condition in and of itself, it can be a symptom of another disorder. | | | | |  A vitrectomy is a surgical procedure that may be carried out for a number of reasons: Improving vision in patients experiencing complications from diabetes. Removing foreign bodies from the eye in cases of trauma. Taking a biopsy to diagnose infections or diseases and as part of other operative procedures on the retina | | | | |  Scientists have developed a laser-based technique that can produce a full 3D image of all the layers of the retina, allowing doctors to better diagnose and treat eye diseases such as cataracts, diabetic retinopathy, and cancer. | | | | |  A coloboma is an eye abnormality present at birth that results from the absence of some tissues in certain parts of the eye. One or both eyes may be affected. The most obvious presentation of a coloboma is as a notch or a gap in some part of the eye, whether that be the iris, the retina, the choroid, or the optic nerve. Colobomas of the eyelids also occur but have a different route of origin. | | | | |  Clinicians who use smartphones to capture photographs of patients' eyes risk misdiagnosis if they base their decisions on objective data extracted from non-calibrated cameras, according to new research published this week in the Nature journal Scientific Reports. | |
