Diagnosis of Syphilitic Bilateral Papillitis Mimicking Papilloedema
Emerging Infectious Diseases, 2020 Syphilis produces myriad nonspecific signs and symptoms. For example, optic disk swelling might be seen in patients with syphilis as a result of cranial hypertension (papilloedema), inflammatory optic neuritis with papillitis, or optic perineuritis.

Actuation of Micro-Optomechanical Systems Via Cavity-Enhanced Optical Dipole Forces [PDF]
, 2007 We demonstrate a new type of optomechanical system employing a movable, micron-scale waveguide evanescently-coupled to a high-Q optical microresonator. Micron-scale displacements of the waveguide are observed for milliwatt(mW)-level optical input powers.

Imaging of the Lamina Cribrosa using Swept-Source Optical Coherence Tomography. [PDF]
, 2012 The lamina cribrosa (LC) is the presumed site of axonal injury in glaucoma. Its deformation has been suggested to contribute to optic neuropathy by impeding axoplasmic flow within the optic nerve fibers, leading to apoptosis of retinal ganglion cells. To

A New Family of Light Beams and Mirror Shapes for Future LIGO Interferometers [PDF]
, 2004 Advanced LIGO's present baseline design uses arm cavities with Gaussian light beams supported by spherical mirrors. Because Gaussian beams have large intensity gradients in regions of high intensity, they average poorly over fluctuating bumps and valleys
