ObjectiveTo investigate the related factors of the retina1 hemorrhage in newborns. Methods9558 newborns included in this observation between March of 2012 and July of 2013 in our hospital. The fundus was examined by the fully-integrated wide-field digital imaging system RetCamⅢat 0-4 days after born. According to the literature, retinal hemorrhage was classified into degreeⅠ, ⅡandⅢ. The condition for baby and the mother during pregnancy were correlatively analyzed. The other factors were analyzed including twins, premature delivery, big baby, mode of delivery, fetal birth, forceps delivery, suction delivery, asphyxia, jaundice, ABO hemolytic, cranial hematoma, intracranial hemorrhage, maternal age, first-time mom, the maternal previous mode of production, emergency delivery, the first stage of labor prolonged, the second stage of labor prolonged, the third stage of labor prolonged, pregnancy-induced hypertension, gestational diabetes, oxytocin, prenatal body mass index (BMI). Multivariate logistic regression analysis was used. ResultsIn 9558 cases of newborns, retinal hemorrhages were found in 2753 infants (28.8%), including 1137 degreeⅠ(41.3%), 895 degreeⅡ(32.5%) and 721 degreeⅢ(26.2%). Multivariate logistic regression analysis showed that the mode of delivery, asphyxia, jaundice, advanced maternal age, maternal previous birth, prenatal BMI is a risk factor for neonatal values retinal hemorrhage (r=0.146, 5.841, 1.847, 0.071, 0.246, 0.965;P < 0.05). The degree of fundus hemorrhage was not related to birth weight and BMI (P > 0.05). ConclusionsThe neonatal retinal hemorrhage rate was 28.8%. Mode of delivery, asphyxia, neonatal jaundice, maternal age, the previous mode of delivery of mothers with more than one previous birth, prenatal BMI values may be risk factors lead to retinal hemorrhage.
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)
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.
Objective To analyze the pathogeny of vitreous re-hemorrhage in proliferative diabetic retinopathy (PDR) after vitrectomy, and to evaluate the treatment effects. Methods The clinical data of 315 eyes of 302 patients with PDR who had undergone vitrectomy were retrospectively analyzed. Thirty-two eyes with vitreous re-hemorrhage after the treatment had undergone vitrectomy again. The follow-up duration was 3-48 months (average 12 months). Results The occurrence of vitreous hemorrhage after vitrectomy was 10%. The reasons included fibrovascular ingrowth at the sclera incision (28%), residual neovascularization membrane or inappropriately treated vascular stump on the surface of optic nerve (19%), insufficient photocoagulation on retina (22%), residual epiretinal neovascularization membrane (9%), retinal vein occlusion (6%), and ocular trauma (16%). Re-hemorrhage occurred 1-210 days (average 51 days) after vitrectomy. The patients with re-hemorrhage underwent cryotherapy for fibrovascular at the incision site, removal of residual neovascularization membrane on the optic nerve and retina, electrocoagulation of the vascular stump, complementary retinal photocoagulation and binding up of two eyes. After the re-treatment, the visual acuity increased in 91% and decreased in 9%. The postoperative complications mainly included vitreous re-hemorrhage, posterior synechia of the iris, lens sclerosis, and delayed healing of corneal epithelium. Conclusion The main reasons of vitreous re-hemorrhage after vitrectomy in patients with PDR include fibrovascular ingrowth at sclera incision, residual neovascularization membrane or inappropriately treated vascular stump on the surface of optic nerve, insufficient photocoagulation on retina, residual epiretinal neovascularization membrane, retinal vein occlusion, and ocular trauma. The efficient methods in preventing and treating re-hemorrhage after vitrectomy are appropriate management of insection sites, completely removal of residual neovascularization membrane on the optic nerve and retina, electrocoagulation of the vessel stump and sufficient retinal photocoagulation.

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.
