PURPOSE To report the in vivo laser confocal microscopy findings from a patient with Descemet's membrane and subepithelial opacity OU. CASE REPORT A healthy 41-year-old male with Descemet's membrane and subepithelial opacity OU was studied. Routine ophthalmic examination, standard slit-lamp biomicroscopy, and in vivo laser confocal microscopic analysis of the entire corneal layer were perform...

BACKGROUND Data suggest a possible protective effect against lens opacity with use of hormone replacement therapy (HRT). However, no agreement exists on which opacity type is affected, and more exploration of the additional role of endogenous estrogen exposure is warranted. OBJECTIVE To determine whether HRT and the prevalence of different lens opacity types are associated after controlling f...

In order to produce realistic renderings for translucent objects, such as foliage or hair, selfshadows have to be used. The first method that succeeds in casting real-time self-shadows is the Opacity Shadow Maps algorithm. However this method suffers from severe layering artifacts unless a large number of opacity maps are used, but that causes the application to have only interactive and not re...

The U.S. Environmental Protection Agency (EPA) Reference Method 9 (Method 9) is the preferred enforcement approach for verifying facility compliance with federal visible opacity standards. Supporters of Method 9 have cited its flexibility and low cost as important technological and economic advantages of the methodology. The Digital Opacity Compliance System (DOCS), an innovative technology tha...
