ALPI vs Medical Therapy Effects on Optic Nerve Structure & Function

Summary

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.
