Glaucoma: Silent Thief of Sight

Ophthalmic Imaging Tools to Detect Glaucoma Progression

Ocular imaging devices provide objective and reliable structural measurements and estimate structural progression that has important clinical implications in ocular pathologies such as glaucoma. This review describes the working principles and main methods for detection of glaucoma progression used in the leading commercially available ocular imaging. This information allows clinicians to bette...

Hiding in Plain Sight – Using Signals to Detect Terrorists

In this paper, we study the interaction between a governmental security agency, such as the Transportation Security Agency, or the Immigration and Naturalization Service, and a terrorist organization, such as Al Qaeda. The governmental agency wants to stop the terrorists, but first must infer whether a visa applicant or an airline passenger is a terrorist or not, on the basis of some observable...

Glaucoma: the silent thief of sight.

Glaucoma damages vision by destroying the optic nerve, which connects your eye to your brain, and carries visual information to your brain for processing. When the optic nerve is damaged from glaucoma, you lose your vision. Your peripheral vision—or side vision—is lost first. If the glaucoma remains untreated, the vision loss creeps in toward the center, first causing tunnel vision, and then, e...

Optimal testing, technologies to detect glaucoma damage and progression

Technologies to Detect Glaucomatous Visual Field Damage There are several ways to identify glaucomatous defects from standard automated perimetry (SAP) print outs (Figure 1). Firstly, inspect sensitivity thresholds at each test point. It is not particularly useful to identify defects, because these values are not age-corrected. In older patients low thresholds could be attribdepression that cou...
