Timothy Kraft, PhD, is an expert in retinal physiology who has studied the function and biophysics of retinal photoreceptors for almost 30 years. Kraft has worked with fellow UAB researcher Dr. Erik ...

A study using zebrafish reveals how brainstem neural networks guide eye movement, offering a new model that mimics these ...

Click on the right arrow to see an alternate view of a developing zebrafish eye. Biology in the background Zebrafish eyes are similar to ours. We share all the major structures, such as a single lens ...

This intricate structure of blue rods and red dots is a cross section through the eye of a damselfly. Insects’ compound eyes are structured very differently than the eyes of humans and other mammals, ...

Prostaglandins (PGs) are ubiquitous compounds found throughout the body, including the eye. They are involved in a variety of ocular functions, two of which are intraocular pressure (IOP ...

PG analogs lower the IOP by improving the outflow of fluid from the eye (pressure dependent and/or pressure independent drainage). Topical PG analog use is associated with iris color changes ...

Short-sightedness can be corrected by placing a concave lens in front of the eye, as shown in the diagrams below. Someone who is long-sighted can see distant objects clearly, but they cannot focus ...
