ABSTRACT
AIM: To analyze the screening status of neonatal fundus disease and the related influencing factors of common fundus retinal hemorrhage in Longhua District of Shenzhen, so as to provide references for the prevention, screening and intervention of neonatal fundus disease in clinical practice.METHODS: A total of 3 101 neonates who received fundus screening in the People's Hospital of Longhua, Shenzen from September 2019 to October 2022 were selected as research objects. The screening results were summarized, and the risk factors for neonatal retinal hemorrhage were analyzed by Logistic regression model.RESULTS: The detection rate of neonatal fundus abnormalities was 12.71%, and the detection rate of neonatal retinal hemorrhage was the highest(12.19%). The other types of fundus abnormalities included periretinal white focus, chromatosis, pigment shedding, choroid coloboma and nystagmus. Hemorrhage grade I accounted for the largest proportion of 378 neonates with retinal hemorrhage(75.66%). Follow-up found that different grades of retinal hemorrhage could be automatically absorbed over time without excessive intervention. Logistic analysis suggested that spontaneous delivery [OR=3.180, 95%CI(1.543～6.555)], twin pregnancy [OR=2.119, 95%CI(1.121～4.007)] and umbilical cord round the neck [OR=1.547, 95%CI(1.239～1.930)] were risk factors affecting neonatal retinal hemorrhage.CONCLUSION: Retinal hemorrhage is the most common type of fundus abnormalities in neonates. Spontaneous delivery, twin pregnancy and umbilical cord around the neck are risk factors of retinal hemorrhage. It is recommended that pay attention to the above factors and choose appropriate intervention means to avoid serious fundus complications.
ABSTRACT
@#AIM: To investigate the clinical effect of scleral buckling surgery combined with 23G vitrectomy in treatment of intraocular foreign body with retinal detachment.<p>METHODS: Totally 72 cases of patients with intraocular foreign bodies and retinal detachment admitted from January 2014 to January 2018 were selected and divided into the control group(36 cases)and the observation group(36 cases)by random number table method. The patients in the control group were treated with 23G vitrectomy surgery while patients in the observation group were treated with scleral buckling surgery on the basis of the treatment in the control group. The changes of intraocular pressure(IOP)and visual acuity, successful reset, recurrence and complications were observed before operation and 3mo after silicone oil was removed.<p>RESULTS: There was no difference in IOP and BCVA between the two groups before operation(<i>P</i>>0.05). Three months after silicone oil was removed, IOP and BCVA in two groups were significantly improved compared with those before operation(<i>P</i><0.05). There was no difference between the two groups(<i>P</i>>0.05). The success rates of one-time anatomical reduction in the observation group and the control group were respectively 97% and 81%(<i>P</i><0.05). The recurrence rates of the observation group and the control group were respectively 6% and 25%(<i>P</i><0.05). The incidence of complications was 22% in the observation group and 31% in the control group(<i>P</i>>0.05).<p>CONCLUSION: The treatment of scleral buckling combined with 23G vitrectomy in the treatment of intraocular foreign body with retinal detachment can significantly improve the IOP and visual acuity of patients, improve the success rate of reduction, reduce recurrence, and have high safety.
ABSTRACT
@#AIM: To observe the clinical effects of different methods of internal limiting membrane peeling in vitrectomy in treatment of idiopathic macular hole(IMH)with macular hole closure index(MHCI)<0.7. <p>METHODS: Totally 88 patients(88 eyes)with MHCI<0.7 IMH admitted from May 2014 to May 2017 were randomly divided into group A(44 eyes underwent extended internal limiting membrane dissection)and group B(44 eyes underwent standard internal limiting membrane dissection). The closure of macular hole, best corrected visual acuity(BCVA), central scotoma and complications were observed between the two groups. <p>RESULTS: At 6mo after operation, the closure rate of macular hole in group A was significantly higher than that in group B(91% <i>vs</i> 75%, <i>P</i><0.05). At 6mo after operation, BCVA in group A was better than that in group B(0.47±0.05 <i>vs</i> 0.74±0.14, <i>P</i><0.05). The percentage of central scotoma eyes was lower than that in group B(4% <i>vs</i> 23%, <i>P</i><0.05), but there was no significant difference in the incidence of complications between the two groups(11% <i>vs</i> 9%, <i>P</i>>0.05).<p>CONCLUSION: Extended internal limiting membrane dissection is more effective than standard internal limiting membrane dissection in the treatment of IMH with MHCI < 0.7, and the former is better for the recovery of retinal function.
ABSTRACT
<p><b>OBJECTIVE</b>To analyze the clinical and molecular characteristics of hemoglobin New York in populations from Guangxi and provide reference data for screening thalassemia.</p><p><b>METHODS</b>A total of 30 691 samples were screened by capillary electrophoresis, and then suspicious samples of Hb New York were identified by DNA sequencing and analysis of blood cell count. Gap-PCR and reverse dot blot hybridization method were used for the detection of common mutations of α and β thalassemia in Chinese.</p><p><b>RESULTS</b>The incidence of Hb New York was 0.12% in Guangxi. The hematological phenotype index (MCV, MCH, Hb New York, Hb A2) of 32 Hb New York heterozygous cases were (91.00±5.19)fl, (29.42±2.04)pg, (44.10±3.12)% and (2.80±0.29)% , respectively. The hematological phenotype index of 4 Hb New York composited SEA heterozygous patients were (68.20±5.26) fl, (21.78±2.15) pg, (36.60±2.00)% and (2.90±0.14)% , of 2 Hb New York composited WS heterozygous patients were (83.90±2.69) fl, (27.70±1.70) pg, (39.70±1.70)% and (3.50±0.21)%. There were statistical differences between three groups (P<0.05). HGB, MCV and MCH of Hb New York heterozygous and Hb New York composited WS heterozygous were normal, and patients with Hb New York composited SEA heterozygous showed mild anemia, decreased MCV and MCH.</p><p><b>CONCLUSION</b>Most of Hb New York were heterozygous and no homozygotes in Guangxi. There were different hematological characteristics in different Hb New York heterozygous patients. Hb New York heterozygous had normal hematological phenotype, ant combined with other types of thalassemia could exhibit symptoms such as anemia.</p>
