MULTICOLOR SCANNING LASER IMAGING IN LIPEMIA RETINALIS.

Purpose: To describe multicolor scanning laser imaging (MSLI) and conventional fundus photography findings in lipemia retinalis (LR).

Methods: We report two LR cases. The first case is a 47-year-old diabetic woman with LR secondary to familial hypertriglyceridemia examined with MSLI, conventional fundus photography, and optical coherence tomography (OCT).

Analysis of Schwalbe's Line (Limbal Smooth Zone) by Scanning Electron Microscopy and Optical Coherence Tomography in Human Eye Bank Eyes.

Purpose: Implantation of intraocular devices may become critical as they decrease in size in the future. Therefore, it is desirable to evaluate the relationship between radial location and Schwalbe's line (smooth zone) by examining its width with scanning electron microscopy (SEM) and to correlate this with observations by optical coherence tomography (OCT).

Methods: Full corneoscleral rings were obtained from twenty-six formalin-fixed human phakic donor eyes.

GABA(A) receptor-mediated signaling alters the structure of spontaneous activity in the developing retina.

Ambient GABA modulates firing patterns in adult neural circuits by tonically activating extrasynaptic GABA(A) receptors. Here, we demonstrate that during a developmental period when activation of GABA(A) receptors causes membrane depolarization, tonic activation of GABA(A) receptors blocks all spontaneous activity recorded in retinal ganglion cells (RGCs) and starburst amacrine cells (SACs). Bath application of the GABA(A) receptor agonist muscimol blocked spontaneous correlated increases in intracellular calcium concentration and compound postsynaptic currents in RGCs associated with retinal waves.
