In the expert consensus published by the Pediatrics in 2013, it was first proposed that anti-VEGF drugs can be considered for retinopathy of prematurity (ROP) with stage 3, zone Ⅰ with plus disease. However, there are many problems worth the attention of ophthalmologists, including the advantages and disadvantages of anti-VEGF therapy compared with traditional laser therapy, systemic and ocular complications after anti-VEGF therapy, and what indicators are the end points of anti-VEGF therapy. Combined with this consensus and numerous research findings, we recommend that the first treatment for anti-VEGF or laser therapy should be considered from disease control effects. For the threshold and pre-threshold lesions, the effect of anti-VEGF therapy for zoneⅡ lesions is better than that for zone Ⅰ lesions and the single-time effective rate is high. So, it is suggested that anti-VEGF therapy should be preferred for the first treatment. The choice of repeat treatment should be considered from the final retinal structure and functional prognosis. Laser therapy is advisable for the abnormal vascular regression slower and abnormalities in the posterior pole. It can reduce the number of reexaminations and prolong the interval between re-examinations. However, the premature use of laser has an inevitable effect on peripheral vision field. Excluding the above problems, supplemental therapy can still choose anti-VEGF therapy again. Most of the children with twice anti-VEGF therapy are sufficient to control the disease. Anti-VEGF therapy should be terminated when there are signs such as plus regression, threshold or pre-threshold lesions controlled without recurrence, peripheral vascularization, etc.
Objective To evaluate the effect of the treatment of diode laser for retinopathy of prematuriy (ROP).Methods Six-eight premature infants, with the gestation lt;32 weeks and birth weight lt;1500 g,were examined 6-7 weeks after birth. The infants suffering from threshold ROP were treated by diode laser through a binocular indirect ophthalmoscope within 48 hours after the confirmation of diagnosis, and with the follow-up of 4～6 moths. Retinal detachment was found in 1 eye 1 month after laser treatment, and scleral encircling operation was performed on the eye which was followed up for 3 months after the operation. Cycloplegic refractive examination was performed on the eyes with threshold ROP 4 months postnatally to determine the presence of refractive errors.Results Six infants (1) eyes were diagnosed as with threshold ROP. The average age of the occurrence of threshold ROP were (10±2.89) (ranging from 6 to 14 weeks) weeks postnatally. The successful rate of diode laser treatment was 91.67%. Retina was flat in one eye treated by scleral encircling operation. Refractive errors of the eye treated by scleral encircling operation was -14.5 D, and the median spherical equivalent errors in other 11 eyes was ( -2.89±-1.86) D. Conclusion The treatment of diode laser is effective for threshhold ROP. (Chin J Ocul Fundus Dis，2003，19：96-98)
ObjectiveTo evaluate the safety and efficacy of 27G micro-incision vitrectomy surgery (MIVS) combined with intravitreal injection of ranibizumab (IVR) in the treatment of retinopathy of prematurity (ROP) with early intervention failure.MethodsRetrospective case series was performed. Fourteen eyes (11 infants) with ROP who underwent 27G MIVS combined with IVR were included from March 2016 to January 2018 in Shenzhen Eye Hospital. Among them, there were 5 males with 7 eyes, 6 females with 7 eyes. The average gestational age of the infants was 28.12±0.90 weeks; the average birth weight was 1 023.64±200.96 g. Before the early clinical intervention, 1 infant (2 eyes) had ROP in zone Ⅰstage 3 with plus disease, 8 infants (10 eyes) had ROP in zone Ⅱ stage 3 with plus disease, and 2 infants had ROP in aggressive posterior ROP. Six eyes underwent laser photocoagulation, while 8 eyes received laser therapy combined with IVR. Six eyes of stage 4A ROP and 8 eyes in stage 4B. Retinal detachment was detected with a mean of 10.44±9.21 weeks. At the time of surgery, the average post-conceptional age was 48.02±8.09 weeks. All the affected eyes were treated with standard sclera with three incisions 27G MIVS. During the operation, only local vitrectomy was performed to release and clear fibroascular proliferation in the optic disc, anterior macular area and pericristal area. After surgery, 10 mg/ml of ranibizumab 0.03 ml was injected into the vitreous cavity. The average follow-up time was 23.36±8.34 months. The primary objectives were the condition of retinal reset, ROP progression control and complications.ResultsAll patients had uneventful surgeries with an average duration of 32.86±9.35 mins. Of the 14 eyes, 12 eyes (85.71%) were controlled, 8 eyes (57.14%) had a good rearrangement of macular structure, while 4 eyes with macular traction. Two eyes had ROP progression, recurrence of retinal detachment, posterior synechia. Complicated cataract was in 1 eye. Proliferative vitreoretinopathy and retinal detachment was in 1 eye after 7 months the operation.Conclusion27G MIVS combined with IVR is a safe and effective treatment for ROP with early clinical intervention failure.
【摘要】 目的 探讨早产儿视网膜病变（retinopathy of prematurity，ROP）的发生率及危险因素。 方法 收集2007年12月-2008年12月在四川省人民医院、成都市妇幼保健院、成都市妇产科医院住院的85例体重≤2 000 g或有严重疾病的早产儿,自出生后4~6周或矫正胎龄32周开始筛查，至周边视网膜血管化。 结果 85例早产儿中，有9例发生ROP，发病率10.58%。其中出生体重lt;1 500 g的早产儿ROP发病率为17.07%，孕周lt;30周的早产儿ROP发病率为40%。 结论 低体重、胎龄小、吸氧为早产儿发生ROP的重要危险因素；尽早进行眼底筛查是早期发现、诊断及治疗ROP的关键。【Abstract】 Objective To investigate the occurrence and risk factors of retinopathy of prematurity (ROP). Methods A total of 85 premature infants were enrolled from Sichuan provincial people′s hospital, Chengdu maternal and child health hospital, and Chengdu obstetric and gynecology hospital. The infants were born between December 2007 and December 2008, with a birth weight less than 2 000 g. The ocular funds examination was carried out four to six weeks after the birth or at the 32nd week of the corrected gestational age;the infants were followed up until the retina was entirely vascularized. Results ROP was found in 9 of the 85 premature infants, with a percentage of 10.58%. About 17.07% premature infants with a birth weight less than 1500 g and 40% infants with a gestational age shorter than 30 weeks had ROP. Conclusions A lower birth weight, a shorter gestational age and oxygen usage are the risk factors of ROP. It′s important to examine the ocular fundus in premature infants as early as possible so as to identify, diagnose and treat ROP at an early stage.
目的:探讨甲状腺功能低下的早产儿血清游离三碘甲状腺原氨酸(Free trilute,FT3)、游离甲状腺激素(Free thyroxin,FT4)、促甲状腺激素(Thyroid stimulation hormone,TSH)水平进行动态态变化及临床意义。方法:我院在2007年11月至2008年4月住院的32例诊断为甲状腺功能低下的早产儿为研究对象,应用放射免疫法检测生后第1天,第7天,第15天,1月和2月血清FT3、FT4、TSH水平。结果:32例诊断为甲状腺功能低下的早产儿中,有窒息史的22例,呼吸窘迫综合症(Respiratory distress syndrome,RDS)10例,单纯性早产5例;出现少吃少动临床症状6例;生后各时期的TSH变化没有统计学差异,生后1、5天与生后1、2月FT3、FT4则可见Plt;0.05具有统计学差异。结论:有窒息和RDS的早产儿中,容易发生甲状腺功能降低,以低甲状腺素血症最为常见,使用左旋甲状腺素后,FT-3、FT-4水平可迅速恢复正常。如果同时存在TSH增高,则TSH水平恢复较慢。
Objective To determine the association between the geneti c polymorp hisms of vascular endothelial growth factor (VEGF) gene and the prognosis for retinopathy of prematurity (ROP) in Chinese. Methods Twenty infants with threshold ROP who had undergone retinal photocoagulation were in the treated group and 20 infants with self-regressed ROP without any treatment were in the control grou p . In the two groups, all the infants had oxygen-breathing history and the sex a n d gestational age were all suitable to be compared, except birth weight. Polymer ase chains reaction-restriction fragment length polymorphism was used to determine the frequencies of VEGF genes in the two groups. Results The frequencies of +405C allele were higher in the treated group than those in the control group (P＜0.05). The frequencies of the VEGF-460T/C and +936C/T ploymorphisms were similar in both groups (P＞0.05). Conclusions The +4 05C/G ge netic polymorphisms of VEGF may correlate to the prognosis of ROP. The carriers of +405CC allele are more susceptible to ROP.
