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 detect the clinical characters and the classification of the congenital retinal vascular anomalies. Methods Nine cases (12 eyes) of congenital retinal vascular anomalies were examined by ocular examination and fundus fluorescein angiography (FFA), in which 3 cases (4 eyes) were examined by indocyanine green angiography (ICGA) simultaneously. Results The congenital retinal vascular anomalies were located at the posterior pole in 8 cases (10 eyes), and extended to peripheral retina in 1 case (2 eyes). Congenital retinal vascular anomalies were classified as follows: congenital retinal macrovessel (1 case, 1 eye); congenital retinal arteriolar tortuosity (2 cases, 3 eyes); inherited retinal venous beading (1 case, 2 eyes); and congenital prepapillary vascular loops (5 cases, 6 eyes). Four cases (5 eyes) were associated with spontaneous hemor rhage induced by physical exertion (Valsalva maneuver). Conclusion Most of the congenital retinal anomalies are located at the posterior pole, involving arteries and veins, and can be associated with spontaneous hemorrhage induced by Valsalva maneuver.

Objective To investigate the related factors of the retinal hemorrhage in high-risk infants (HRI). Methods Eight hundred and sixty HRI with histories of high-risk pregnancy and/or neonatal asphyxia after 1-5 days of birth were enrolled in this study.In 860 cases of HRI, 498 infants were vaginal delivery and 362 infants were delivered through cesarean sections. Among 498 vaginal delivered infants, 407 infants were eutocia and 91 infants were with forceps delivery; 298 infants were born following normal labor, 102 infants experienced prolonged labor, and 98 infants were urgent birth. The retinal hemorrhages were observed and conditions were graded into three degrees of Ⅰ, Ⅱ, and Ⅲ. Conditions of neonatal asphyxia were evaluated based on criteria of Apgar score. The incidence of retinal hemorrhage in the different types of deliveries and labor processes were compared, and the relationship between degree of retinal hemorrhage and grade of neonatal asphyxia were analyzed. Results In 860 cases of HRI, retinal hemorrhages were found in 202 infants (23.5%). Within these 202 infants, 75 infants (37.1%) were Ⅰ degree retinal hemorrhage, 75 infants (37.1%) were Ⅱ degree retinal hemorrhage, and 52 infants (25.8%) were Ⅲ degree retinal hemorrhage. In these 202 infants of retinal hemorrhage, 172 infants (85.1%) had histories of asphyxia; 119 infants (69.2%) were graded as mild asphyxia-risk, and 53 infants (30.8%) were graded as severe asphyxiarisk. There was a statistical difference of the degree of the retinal hemorrhage between the mild and severe asphyxia-risk infants (chi;2=34.61,P＜0.01). The incidence of retinal hemorrhage after vaginal delivery was higher than cesarean section delivery with significant statistical difference (chi;2=30.73,P＜0.01). The incidence of retinal hemorrhage after forceps delivery was significantly higher than eutocia with statistical difference (chi;2=62.78,P＜0.01). Both prolonged and urgent childbirth had statistically significant higher incidences of retinal hemorrhage compared to normal labor in the process of vaginal delivery (chi;2=45.86, 71.51; P＜0.01). Asphyxia, types of delivery, prolonged and urgent labors were risk factors of retinal hemorrhage for HRI (r=7.46,4.87,15.03,6.47;P＜0.01). Conclusions The incidence of retinal hemorrhage in high-risk infant was 23.5%. And, asphyxia, types of delivery, prolonged and urgent labors may play roles of risk factor in retinal hemorrhage of HRI.
PURPOSE:To search for the occult choroidal neovascularization(CNV)of age-related macular degeneration (AMD)with macular hemorrhage using indocyanine green angiography(ICGA). METHODS:FFA and ICGA were performed in a series of 22 cases(24 eyes)of AMD with macular hemorrhage,and the findings of both angiograms were compared each other. RESULTS :ICGA was found to be superior than FFA in evaluating the occult CNV of AMD with hemorrhage owing to the following outstanding findings in this series,i.e,in judging the presence,position,number and range of the occult CNV. CONCLUSION:ICGA is an important technique in diagnosing the subretinal occult CNV in AMD with macular hemorrhage,and useful in selecting therapeutic measures including photocoagulation and surgical treatment. （Chin J Ocul Fundus Dis,1997,13: 146-149）
ObjectiveTo evaluate the functional and anatomical outcomes of autologous single retinal pigment epithelium (RPE) transplantation for severe obsolete submacular hemorrhage (SMH) in late age-related macular degeneration (AMD). MethodsA retrospective clinical study. From January 2012 to December 2015, 11 patients with AMD (11 eyes) with obsolete SMH who were diagnosed and treated by pars plana vitrectomy (PPV) combined with autologous RPE transplantation at the Department of Ophthalmology, Xin Hua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were included. Among them, there were 9 eyes in 9 males and 2 eyes in 2 females. All the eyes underwent the examinations of best corrected visual acuity (BCVA) and optical coherence tomography; 4 eyes underwent macular fixation function (MAIA) at the same time. The BCVA examination was carried out using the international standard visual acuity chart, which was converted into logarithm of the minimum angle of resolution (logMAR) visual acuity during statistics. All eyes were treated with PPV combined with autologous single-layer RPE transplantation or autologous RPE-choroidal full-thickness transplantation, and were divided into S group and C group, with 5 and 6 eyes respectively. The differences of age (t=－0.363), gender composition ratio (χ2=0.549), course and thickness of SMH (t=0.118, 0.231), average times of anti-vascular endothelial growth factor drug treatments (t=0.129), times of PPV (t=－0.452) between the two groups were not statistically significant (P>0.05). The follow-up period was 6-40 months after the operation, and the BCVA, MAIA, graft status and complications of the eyes after the operation were observed. The comparison of continuous variables between groups was performed by independent-sample t test; the comparison of categorical variables was performed by χ2 test. ResultsAt the last follow-up, the average logMAR BCVA of the eyes in group S and C were 1.62±0.34 and 1.03±0.20, respectively; group C was better than group S, however, the difference was not statistically significant (t=1.532, P=0.160). There were 4 eyes (80%, 4/5) and 6 eyes (100%, 6/6) in S group and C group with BCVA better than preoperative, the difference was no statistical significance (χ2=0.677, P=0.895). There were 2 (40%, 2/5) and 3 (50%, 3/6) eyes with logMAR BCVA better than 1.0 in S group and C group, and the difference was not statistically significant (χ2=0.572, P=0.423). After the operation, 6 eyes of grafts were in good condition and 5 eyes were in poor condition; the BCVA of grafts in good condition was significantly higher than that of poor condition, the difference was statistically significant (t=4.894, P=0.001). Among the 4 eyes that underwent MAIA examination, 2 eyes were unstable and diffusely fixed on the graft; the fixation point was located at the normal retina adjacent to the graft area in 2 eyes. Secondary subretinal hemorrhage occurred in 3 eyes after the operation; the intraocular pressure was high in 1 eye after the operation. During the follow-up period, no intraocular infection, secondary retinal detachment, recurrent choroidal neovascularization or low intraocular pressure occurred in all eyes. ConclusionsBoth autologous single-layer RPE transplantation and autologous RPE-choroidal full-thickness transplantation can help stabilize or even improve the visual function of eyes with severe SMH secondary to advanced AMD. The visual acuity after surgery is closely related to the state of the graft.
