Isolating triamcinolone acetonide particles for intravitreal use with a porous membrane filter.

Purpose: To report a new, simple, rapid method to isolate triamcinolone acetonide particles and to remove additives from its commercially available suspension (Kenacort-A) for intravitreal use.

Methods: The contents of a Kenacort-A vial (40 mg triamcinolone acetonide suspended in 1.0 mL vehicle) were loaded into a syringe and passed through a porous membrane filter with 0.

Optical coherence tomographic and angiographic findings of a case with subretinal toxocara granuloma.

Purpose: To study a case with a subretinal Toxocara granuloma.

Design: Interventional case report.

Methods: A patient with a exudative macular lesion, diagnosed as ocular toxocariasis, was examined with optical coherence tomography (OCT) and angiography before and after systemic corticosteroid and anthelminthic therapy.

Role of xanthurenic acid 8-O-beta-D-glucoside, a novel fluorophore that accumulates in the brunescent human eye lens.

We have been able to identify a blue fluorophore from the low-molecular weight soluble fraction of human adult nondiabetic brunescent cataract lenses as xanthurenic acid 8-O-beta-D-glucoside (XA8OG) (excitation = 338 nm and emission = 440 nm). To determine the role of this fluorophore in the lens, we have examined its photophysical and photodynamic properties. We found XA8OG to have a fluorescence quantum yield (phi) of 0.
