Retinal ganglion cells are usually not able to regenerate their axons after optic nerve injury or degenerative disorders, resulting in lifelong visual loss. This situation can be partially reversed by activating the intrinsic growth state of retinal ganglion cells, maintaining their viability, and counteracting inhibitory signals in the extracellular environment. Advances during the past few years continue to extend the amount of regeneration that can be achieved in animal models. These findings give hope that clinically meaningful regeneration may become a reality within a few years if regenerating axons can be guided to their appropriate destinations.

The problem of multifocal glasses is that the vision of objects on the floor must be made through the lower segment of the lens and it can imply an alteration in the perception of deepness, which probably explains the fact that older adults with multifocal glasses are at a high risk of falls.

The management of monocular infantile cataract is one of the most time-consuming medical tasks that infants' parents and ophthalmologists undertake. Surgical care is only the first step. Associated management issues create a life-long relationship for the child with ophthalmology. Problems that these families encounter include a frequently changing refractive error, amblyopia, glaucoma, lost contact lenses, corneal abrasion/erosion, strabismus, and time and expenses associated with frequent office visits and optical correction replacement.

Emergence of antibiotic-resistant bacteria is a consequence of increasing antibiotic selection pressure caused by the demand for new antibiotics for new and emerging infections, emergence of resistant organisms, inappropriate use of antibiotics in medical practice, and use of antibiotics in industry.

Biologic therapy may be broadly defined as treatment using an agonist or an antagonist to specifically enhance or suppress the level of a naturally occurring protein molecule to manipulate a disease state. Agonists used in biologic therapy include a variety of cytokines and growth factors. Antagonists include monoclonal antibodies and other agents capable of binding soluble and/or cell membrane–bound proteins.

Surgically implanting lenses in the eyes of infants born with cataracts might increase the rate of surgical complications, said a Baylor College of Medicine eye specialist who took part in a study comparing the use of a contact lens with surgically placing a plastic lens in the baby's eye after removing the cataract. She advised caution in considering the placement of an intraocular lens in infants. While placement of an intraocular lens eliminates the need to insert and remove contact lenses in infants, it might not be a superior treatment, a consortium of researchers including BCM said in a report that appears online early in the Archives of Ophthalmology .

In this issue of the Archives, Berson and colleagues1 report the results of a well-designed and well-executed clinical trial that extends their studies of the effects of nutritional supplements on the rate of progression of retinitis pigmentosa (RP).

For those of us of a certain age, conventional wisdom stated that elevated intraocular pressure (IOP) caused glaucoma, and lowering IOP was the only effective way to prevent and treat it.

In 1996, the U. S. Preventive Services Task Force (USPSTF) advised visual screening in subjects over 65, with a level B recommendation, on the basis that vision measurement is a cheap procedure, which has no risks.
