Abstract:
Objective To observe the efficacy of single Nd-YAG laser treatment for the sub-inner limiting membrane(sub-ILM) haemorrhages in the macular region.Methods This is an uncontrolled case series retrospective study.Nd-YAG laser was performed for 6 patients (6 eyes) with premacular sub-ILM haemorrhages.The best corrected visual acuity(BCVA) and optical coherence tomography(OCT) in macular were observed at 1 day,1 week,1 month and 3 months after operation.The conditation of hematopoietic drainage and complications of macular retina were recorded.Results Sub-ILM haemorrhages were clinically confirmed in 6 patients (aged from 23 to 60 years old),including 4 cases of paroxysm associated with cough,1 case of hypertension,and 1 case of diabetic retinopathy.Funduscopic examination showed sub-inner limiting membrane hemorrhage in the macular region,BCVA count finger (CF) was 0.05 (averagely 0.03).The onset time was from 5 hours to 12 days.All the patients were treated with Nd-YAG laser treatment once,and all of them resulted in excellent partial visual recovery immediately.The average hemorrhage absorption time was 2 weeks.OCT examination showed macular retinal inner limiting membrane calm and foveal shape recovery at 3 month after laser treatment.However,the two patients with hypertension and diabetes recieved vitrectomy at 2 weeks and 1 month after laser surgery respectively because of serious vitreous hemorrhage.Conclusion Single Nd-YAG laser is a safe and effective method in the treatment of simplicity sub-ILM haemorrhages.
