Objective To analyze the reasons, methods of treatment, and effects on prognosis of vitreous hemorrhage after vitrectomy in patients with diabetic retinopathy. Methods The clinical data of 98 patients (122 eyes) with diabetic retinopathy (VI stage) who had undergone vitrectomy were retrospectively analyzed. Results Post-vitrectomy vitreous hemorrhage (gt;grade 2) was found in 25 eyes with the occurrence of 20.5%, in which the hemorrhage occurred 1 week after the surgery in 8 eyes, 1 week to 1 month in 6 eyes, and more than 1 month in 11 eyes. In the 25 eyes, C3F8 tamponade eyes occupied 31.1%, silicone oil tamponade eyes occupied 6.1%, air tamponade eyes occupied 33.3%, and infusion solution tamponade eyes occupied 26.3%. Peripheral fibrovascular proliferation was found in 9 eyes. In the 3 eyes with silicone oil tamponade, the hemorrhage was absorbed in 2, and epiretinal membrane was found in 1 which was moved when the silicon oil was taken out. In the 22 eyes without silicone oil tamponade, the hemorrhage was absorbed in 6 and aggravated in 2 without any timely treatment, neovascular glaucoma occurred in 1, and wide vitreo-retinal proliferation and retinal detachment was observed in 1 with the visual acuity of no light perception. Operations such as fluid-air exchange, vitrectomy were performed on 14 eyes 2 weeks after the hemorrhage absorption stopped. Recurrent vitreous hemorrhage was not found in 12 eyes after single operation. At the end of the follow up period, the visual acuity was no light perception in 3 eyes, hand moving in 2 eyes, counting finger-0.1 in 10 eyes, under 0.3 in 4 eyes, and over 0.3 in 6 eyes. Conclusion Most of the patients with vitreous hemorrhage after vitrectomy due to DR had peripheral fibrovascular proliferation. The visual prognosis after re-operation is good.

Objective To investigate the clinical characteristics and the related factors of peripapillary subretinal hemorrhage (PPSRH). Methods The clinical documents of fundus fluorescein angiography (FFA) of 23 patients (23 eyes) with PPSRH were retrospectively analyzed. Results All of the 23 eyes was myopes with middle or slight degree, and the corrected visual acuity was≥1.0. Among the 23 patients, 9 eyes were PPSRH, 13 eyes were PPSRH with disc hemorrhage, and 1 eye was PPSRH with disc and vitreous hemorrhage. All of the PPSRH was localed at the nasal edge of optic disc. Through FFA the hemorrhage showed blocked fluorescence and the optic disc showed nodular hyperfluorescence at the late phase, and nothing abnormal in the unaffected eyes. Conclusion PPSRH might be related to buried optic disc drusen. (Chin J Ocul Fundus Dis, 2002, 18: 96-97)
Objective To investigate the incidence, risk factors and relationship with intraocular hemorrhage of Tersonprime;s syndrome among patients with spontaneous subarachnoid hemorrhage (SSAH) after emergency admission. Methods Seventy-four consecutive patients with SSAH from June 2010 to September 2011 were prospectively examined. A direct ophthalmoscope examination was performed in all participants within three hours after emergency admission. If circumstances permit, fundus photos were taken. When initial fundus examination was conducted, the Hunt-Hess grade was classified by the brain surgeon. The fundus examination was taken on the 1st, 3rd, and 7th day, 2 weeks, 1 month, and 3 months after emergency admission. The details were recorded, including sex, age, bleeding patterns, Hunt-Hess grade and death. The incidence of Tersonprime;s syndrome was analyzed and correlated with sex, age and Hunt-Hess grade. The relationship between intraocular hemorrhage and Hunt-Hess grade and mortality was analyzed. Results Among the 74 patients, 19 were suffering from Tersonprime;s syndrome, 31 eyes involved. The incidence of Tersonprime;s syndrome was 25.7%. Statistical analysis demonstrated that the sex of the patient was randomly distributed (chi;2=0.071,P=0.790), and the age components were also randomly distributed (Fisherprime;s exact test.P=0.203). The Hunt-Hess grade components were nonrandomly distributed (Fisherprime;s exact test，P=0.000). Among the patients with preretinal hemorrhage and vitreous hemorrhage, Hunt-Hess grade Ⅴ was in 76.9% patients; among inte-retinal hemorrhage, Hunt-Hess grade was in 16.7% of patients. The distribution was non-random (Fisherprime;s exact test.P=0.041). All intraocular hemorrhages were found at the time of first fundus examination. The mortality from Tersonprime;s syndrome was 68.4% (13/19) according to the follow-up investigation. The mortality in patients with vitreous hemorrhage and preretinal hemorrhage was statistically different (Fisherprime;s exact test.P=0.046) from patients with inter-retinal hemorrhage. Among the six recovered Tersonprime;s syndrome patients, two of them were recovered from vitrectomy, and the other four were recovered from selfabsorption. Conclusions A higher frequency (25.7%) of Tersonprime;s syndrome was observed in patients with SSAH. The incidence is highly related to the general condition of the patient but not to the sex or age. Intraocular hemorrhage is more likely to happen in the early time of SSAH. People with more severe intraocular hemorrhage may have worse general condition or higher mortality.
Vitreous hemorrhage in children is caused by trauma or non-traumatic factors. Long-term vitreous hemorrhage not only affects children's vision, but also can lead secondary glaucoma, traumatic retinal detachment and other serious complications. Ocular trauma, some ocular and systemic diseases are the common etiology leading to vitreous hemorrhage in children. A small amount of vitreous hemorrhage can be treated by observation and conservative treatment. However, if the vitreous hemorrhage has no obvious absorption or serious complications appeared, it needs to be treated by surgery. The choice of treatment time and methods need to be further studied.
