A corneal laceration is cut on the cornea, the clear front window of the eye. It is usually caused by something sharp flying into the eye or something striking the eye with significant force, like a metallic hand tool. A corneal laceration is deeper than a corneal abrasion, cutting partially or fully through the cornea. If the corneal laceration is deep enough (called a full thickness laceration)

Posted by Bharat (#1) 4608 days ago (Editorial)
If you look directly at the camera during a flash photo, the light from the flash entering your eyes may reflect off the retina, as if reflecting off a mirror. The back of the eye contains many small blood vessels, which give it a reddish appearance. Therefore, the reflected light looks red. To prevent this reflection from ruining their photographs, professional photographers use a flash that is
Macular Edema in Diabetes
Posted by Bharat (#1) 4611 days ago (Editorial)
The Early Treatment Diabetic Retinopathy Study (ETDRS) set the guidelines for the treatment of diabetic macularedema (DME). Since that time, the standard of treatment for diabetic macular edema has been glycemic control as demonstrated by the Diabetes Control and Complications Trial (DCCT), optimal blood pressure control as demonstrated by the United Kingdom Prospective Diabetes Study (UKPDS), an
What Is a Macular Hole?

The macula is a very small area at the center of the retina — a thin layer of light-sensitive tissue that lines the back of the eye. Light rays are focused onto the retina, where they are transmitted to the brain and interpreted as the images you see. It is the macula that is responsible for your pinpoint vision, allowing you to read, sew or recognize a face. As we grow older, the thick vitreous
Is it possible to tell what someone is feeling by looking at only his or her eyes?
Posted by Bharat (#1) 4611 days ago (Editorial)
The pupil (the black circle in the middle of the colored iris) may indicate what someone is feeling. Several factors determine the size of the pupil. Primarily, the pupils dilate (get bigger) or constrict (get smaller) to control the amount of light that enters the eyes. In addition, emotions can change the size of your pupils. When you experience pleasure, your pupils briefly dilate. Anger and f
Vision Problems Decreasing in People With Diabetes But Too Few Getting Routine Eye Exams
Posted by Bharat (#1) 4611 days ago (Editorial)
Vision problems and vision loss are known complications of diabetes, but things seem to be getting better. The percentage of adults with diabetes who say they have vision problems has dropped from 24% in 1997 to 17% in 2010. That’s the good news. The not-so-good news is that only 63% of people with diabetes and vision problems get the recommended annual eye exam. To see more details, visit
The Eye Of The Fly: Researchers Discover Possible Key To Degenerative Nerve Diseases
Posted by Bharat (#1) 4611 days ago (Editorial)
Researchers at the University of Wisconsin-Madison and collaborators have discovered a powerful new protein in the eye of the fruit fly that may shed light on blinding diseases and other sensory problems in humans. the scientists note that similar but yet- to-be-identified proteins in the eye and brain could help explain age-related macular degeneration and retinitis pigmentosa, as well as Huntin
Study Describes How Space Flight Impacts Astronauts' Eyes and Vision
Posted by Bharat (#1) 4617 days ago (Editorial)
A new study sponsored by NASA finds that space flights lasting six months or more can cause a spectrum of changes in astronauts' visual systems. Some problems, including blurry vision, appear to persist long after astronauts' return to Earth. The results are affecting plans for long-duration manned space voyages, such as a trip to Mars.Cyanoacrylate Glue Effective in Half of Corneal Perforations.
