Premacular subhyaloid hemorrhage is one of the etiologies of sudden visual loss. It might be due to vascular or blood abnormalities or Valsalva retinopathy. Spontaneous absorption of blood may take months and result in macular complications and permanent impairment of vision as stated in my study. Posterior hyaloidectomy by Nd-YAG laser is an outpatient procedure which may avoid the need for complex surgical interventions. This study evaluates the success of this approach in patients with premacular subhyaloid hemorrhage of different etiologies as compared to patients treated conservatively. The study was conducted in Rama Medical College Hospital and Research Centre (RMCH & RC) from August 2012 to December 2013. It includes 14 eyes of 14 patients. We divided patients in two groups of seven patients in each group. One group of seven patients for conservative treatment while other group had Nd -YAG laser hyaloidectomy. The mean pretreatment hemorrhage measured 2.28 disc diameters (range 1.0-3.0) and mean duration of haemorrhage is 1.85 days both in conservatively treated patients as well as in patients who had undergone Nd- YAG laser hyaloidectomy. Visual acuity in all cases before treatment was hand movement to 3/60.Conservatively treated patients could not regain visual acuity 6/6 while patients who had undergone Nd-Yag hyaloidectomy regained visual acuity 6/6 after treatment. No retinal damage or rebleeding occurred due to the laser treatment. Nd- YAG laser hyaloidectomy is very much useful for treating sub macular hyaloid haemorrhage as compared to conservative treatment.
