Analysis of TORCH results of retinal exudative changes in neonates

AIM:To explore the relationship between retinal exudative changes in neonates and perinatal toxoplasmosis,others,rubella,cytomegalovirus,and herpes simplex virus(TORCH)infections,as well as the characteristics of TORCH infection in neonates with retinal exudative changes.METHODS:Retrospective study.A total of 612 neonates with retinal exudative changes detected during ophthalmic screening in our hospital from May 2019 to March 2023 were selected.TORCH tests were performed on these neonates,and the results were subjected to statistical analysis to determine the infection characteristics.The neonates with retinal exudative changes were grouped by sex and age,the characteristics of TORCH infection were analyzed,and the positive rates were compared.RESULTS:Among the 612 neonates with retinal exudative changes,the highest positive rate was observed for cytomegalovirus(CMV-IgG)(96.7%),followed by rubella virus(RV-IgG)(73.9%).Mixed infections with two or three viruses were also observed,with the highest positive rate for mixed infection of RV-IgG and CMV-IgG reaching 71.2%.There was no statistically significant difference in TORCH infection among neonates of different sex(P>0.05).However,there were statistically significant differences in RV-IgG and CMV-IgM infections with retinal exudative changes among neonates of different age groups(P<0.05).CONCLUSION:Perinatal TORCH infection may be an important factor causing retinal exudative changes in neonates.The differences in various infections are not related to sex but are related to different age groups.

A algorithm for prediction of exudative retinal detachment risk of patients with pregnancy-induced hypertension

AIM:To investigate the risk of exudative retinal detachment(ERD)morbidity in patients with pregnancyinduced hypertension(PIH)by using the logistic regression combined with the receiver operating characteristic(ROC)curve.METHODS:A total of 46 patients with ERD and 142 patients with non-ERD were diagnosed as PIH from January 2017 to February 2020.A retrospective comparison of the clinical manifestations and laboratory tests were conducted.The risk of ERD morbidity with PIH was predicted by using logistic regression combined with an ROC curve model.RESULTS:There was no significant difference in age and body mass index between the two groups before pregnancy(P>0.05).However,significant differences were found in gestational weeks,duration of hypertension,maximum and minimum systolic and diastolic blood pressure(BP),and plasma total protein(PTP)concentration between the two groups(P<0.05).Binary logistic regression analysis showed that the maximum systolic BP(OR=1.050,95%CI:1.016-1.085)and PTP concentration(OR=0.764,95%CI:0.702-0.832)were independent prediction risks of ERD in PIH.The sensitivities of maximum systolic BP,PTP concentration and combined diagnosis were 0.717,0.870,and 0.870,respectively;the specificities were 0.617,0.837,and 0.908,respectively;the area under the curve(AUC)was 0.707(95%CI:0.622-0.792),0.917(95%CI:0.868-0.967),and 0.933(95%CI:0.890-0.975),respectively;the AUC of combined diagnosis was higher than that of single diagnosis(P<0.01).CONCLUSION:Logistic regression and ROC curve model combined with maximum systolic BP and PTP can improve the early identification of high-risk PIH patients in the hospital.

Exudative Retinal Detachment Associated with Complicated Retrobulbar Anesthesia

Retrobulbar anesthesia (block) is used for many ocular surgeries, whereas it is well known that this procedure has complications such as for retrobulbar hemorrhage, globe perforation, optic nerve injury and brain stem anesthesia. In this report, we present a unique case in the literature of isolated exudative retinal detachment (RD) secondary to iatrogenic retrobulbar hemorrhage. A 73-year-old woman underwent retrobulbar block for combined phaco-vitrectomy. Immediately after the injection, progressive proptosis was recognized. The globe was decompressed and she underwent combined phaco-vitrectomy after stabilization of the eye on the same day. At the be-ginning of the vitrectomy, a dome shaped serous RD was observed in the infero-temporal quadrant. Peripheral exploration was performed, whereas there was no retinal tear or hole. On the first day postoperatively, serous RD was disappeared. In conclusion, this report suggests that increased intraorbital pressure secondary to iatrogenic retrobulbar hemorrhage might lead exudative RD.

Spontaneous exudative retinal detachment in a patient with sturge-weber syndrome after taking arginine, a supplement for erectile dysfunction

Background:Patients with Sturge-Weber syndrome can have ipsilateral diffuse or circumscribed choroidal hemangiomas.These hemangiomas have been seen to undergo spontaneous exudative or hemorrhagic retinal detachments.There is no definitive treatment for these types of retinal detachments,but radiotherapy,photodynamic therapy,oral propranolol,pegaptinib and bevacizumab have been used.Case presentation:A 26-year-old male with Sturge-Weber Syndrome developed an exudative retinal detachment that occurred immediately after taking a supplement containing arginine.The patient was treated with intravitreal bevacizumab 1.25 mg in 0.05 ml solution.Resolution of the retinal detachment was seen after 4 treatments over a six-month period.Conclusions:Arginine and other medications that cause a release of nitric oxide may lead to intravascular leakage and exudative retinal detachments in patients who have a choroidal hemangioma.
