Objective To analyze the clinical features of retinal detachment in macular spontaneous hemorrhage to improve the level of diagnosis and treatment of this disease. Methods The serial clinical data of 23 patients (23 eyes) with subretinal hemorrhage in macular region with the area over 4DDtimes;5DD who were diagnosed in our hospital from Sep, 1998 to Mar, 2003 were analyzed retrospectively. The patients included 12 males (12 eyes) and 11 females (11 eyes) with the average age of 64.1 (47-75). Fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA) and B-scan examination were performed on the patients to analyze the pathogenic factors, and the visual acuity and manifestation of ocular fundus were observed during the 8-24 months followed-up period. Results The visual acuity decreased to less than 0.2 or light perception suddenly in all affected eyes. In 23 eyes, choroidal neovascularization (CNV) of age-related macular degeneration (AMD) was found in 7, polypoidal choroidal vasculopathy (PCV) was in 5, retinal macroaneurysm was in 2, and unknow pathogenic factor in 9. Among the 23 eyes, hemorrhage was absorbed and no cicatritial formation at the fovea in 3 eyes with the visual acuity of 0.4-0.8; scar and pigment proliferation in the hemorrhage area were seen in 12 eyes with the visual acuity of finger counting (FC) to 0.2; combined vitreous hemorrhage was found in 8 eyes, including massive scar in the macular area in 3 who had undergone vitrectomy with the visual acuity of FC/66cm to 0.2 and blindness in the other 5 eyes. Conclusion Spontaneous hemorrhagic retinal detachment always arises in old people whose symptoms were sudden decrease or loss of the visual acuity. The configuration of the hemorrhage is local and diffuse. The prognosis of the visual acuity of most of the patients is poor due to the serious tissue injury in macula area.

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.
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.

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）
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)
