NCT00485238
The aim is to determine which approach, immediate argon laser peripheral iridoplasty or conventional systemic medical treatment efficiently breaks acute angle closure attack without consequent visual morbidities. The specific objectives are to see whether sudden intraocular pressure(IOP) lowering brought about by laser iridoplasty or medical treatment affects optic nerve head structure and function and identify if immediate decompression is associated with greater incidence of ocular problems like corneal endothelial compromise, optic disc edema, macular edema, decompression retinopathy, cataract formation, progression to chronic angle closure.
NCT00452998
Sequential Laser Iridotomy uses argon and Nd:yag laser in the first and second steps, respectively. Using q-switched 532 nm laser in the second step is hypothesized to be as good and effective as the conventional Nd:yag laser, because it selectively targets pigmented cells and delivers a short pulse duration of 3 nanoseconds, causing less thermal and collateral damage.
NCT00467311
Hypothesis: Cystatin C compared with creatinine is a better and earlier marker of contrast-induced nephropathy in high and intermedium risk cardiac catheterization patients. Primary Objective: Establish if Cystatin C is superior detecting contrast-induced nephropathy than creatinine in high and intermedium risk cardiac catheterization patients.
