AIM: To investigate the clinical efficacy of jolethin tablets as the adjunctive treatment for vitreous hemorrhage. METHODS: Thirty-two cases 32 eyes with vitreous hemorrhage caused by oculopathy were randomly divided into two groups with 16 cases in jolethin adjunctive treatment group received not only conventional treatment of haemostasis, promoting blood flow, and expanding blood vessel, but also received lecithin complexation iodine(jolethin) tablet which was taken orally, 1.5mg(100μg iodine included in it)every time, tid. totally for 60 days, the other 16 cases were in control group only received conventional treatment of haemostasis, promoting blood flow and expanding blood vessel. The observation course was 3 months in both two groups. Visual acuity, slit-lamp microscope examination, preset lens fundus examination and the grade of vitreous hemorrhage were performed on each patient pretreatment and 2, 4,8 and 12 weeks after the treatment. RESULTS: The degree of vitreous hemorrhage in therapy group at 4 weeks after treatment was equal to the degree of vitreous hemorrhage in control group at 8 weeks after treatment. 12 weeks after treatment, the vision distribution of therapy group was as follows: none of patients was light perception - 0.1, three patients were 0.15- 0.3 and thirteen patients were over 0.3. But in control group 12 weeks after treatment, the vision distribution was as follows: two patients were light perception - 0.1, seven patients were 0.15- 0.3 and seven patients were over 0.3. The difference between the two groups had statistical significance(P<0.05). CONCLUSION: Lecithin complexation iodine(jolethin) can improve the absorption of bleeding and effusion, assistantly cure vitreous hemorrhage, decurtate recovery time of vitreous hemorrhage, and recover the better visual function.
