BACKGROUND AND OBJECTIVE The commercially available optical coherence tomography (OCT) scanner displays images in a pre-set window regardless of the projected scan length on the retinal surface. The aim of this study was to demonstrate the true dimensions of proportion-corrected OCT images and the additional information present in grayscale images. (More)
PURPOSE Published series of peripapillary retinal nerve fiber layer (RNFL) measurements using optical coherence tomography (OCT) have sampled 100 evenly distributed points on a 360 degrees peripapillary circular scan. The goal of this study was to determine whether a four-fold increase in sampling density improves the reproducibility of OCT measurements. (More)
We have previously demonstrated that halofuginone, a low molecular weight quinazolinone alkaloid, is a potent inhibitor of collagen alpha1(I) and matrix metalloproteinase 2 (MMP-2) gene expression. Halofuginone also effectively suppresses tumor progression and metastasis in mice. These results together with the well-documented role of extracellular matrix(More)
OBJECTIVE To assess the internal reflectivity of the retinal nerve fiber layer in normal, ocular hypertensive, and glaucomatous eyes using optical coherence tomography. METHODS All patients underwent complete ophthalmic examination and achromatic automated perimetry. Intraocular pressure was 21 mm Hg or less for low-tension glaucoma and normal eyes and at(More)

In rabbits, the amplitude of a-waves and b-waves in the ERG declined following ocular contusion; however, the oscillatory potentials did not change markedly. In the anisodine therapeutic group, the amplitude of a-waves recovered higher than did that in the control group at the 2nd and 4th week post-traumatic, while all a-waves recovered at the 6th week in(More)

The hemodynamic changes in rabbit eyes following contusion were studied with rheoophthalmography (ROG), in which the wave amplitudes were markedly reduced and then recovered in 3 weeks, while in the anisodine-I treated group they recovered in 2 weeks. Contusion of 3 joules disrupted the choroidal circulation and damaged the retina. Anisodine-I improved the(More)
