Abstract
To evaluate the efficacy, visual outcome and complication following Nd:Yag laser hyaloidtomy for subhyaloid hemorrhage. This interventional case series was managed at LRBT, Free Base Eye Hospital Karachi from January 2010 to December 2010. It included 30 eyes of 30 patients with subhyaloid hemorrhage due to different causes which underwent Nd: Yag laser sublyaloidotomy Results: Out of thirty patients, eighteen (60%) were male and twelve (40%) were females. Mean age was 32.57 years. Males pre-dominated the study. Pre laser visual acuity was between counting finger at one meter in 22 patients (73.33%) and between counting finger one meter to hand movement in 8 patients (26.66%). Vision improved to 6/6 in 10 patients (33%), 6/9 - 6/12 in 17 patients (56.66%) and between 6/24 - 6/60 in 3 patients (9.99%) at the end of follow up. Complications were persistent vitreous hemorrhage in one (3.33%) patient, failed drainage in one (3.33%) patient and metamorphopsia in one (3.33%) patient. Nd: Yag laser hyloidotomy is an excellent technique for management of Subhyaloid hemorrhage with early visual recovery provided there is no macular pathology.
