Combination of Intravitreal Ranibizumab and Laser Photocoagulation for Aggressive Posterior Retinopathy of Prematurity

Purpose

To report on 2 cases of aggressive posterior retinopathy of prematurity (ROP) treated with intravitreal ranibizumab (Lucentis^®) and laser photocoagulation.

Methods

Two premature females, born at 25 and 26 weeks’ gestation with a birth weight of 530 and 550 g, respectively, with aggressive posterior ROP received combined treatment with laser photocoagulation and intravitreal ranibizumab (0.3 mg [30 µl]) to each eye. Structural outcomes were evaluated by indirect ophthalmoscopy and documented by retinography.

Results

An intravitreal injection was made at 34 weeks of postmenstrual age in the first case, followed by laser photocoagulation 1 week later. There was a partial regression of ROP with treatment. Five weeks later, neovascularization regrowth with bleeding in both eyes (intraretinal and subhyaloid) occurred and retreatment with combined therapy was performed. In the second case, single therapy with laser photocoagulation was made at 34 weeks of postmenstrual age. In spite of the confluent photocoagulation in the avascular area, progression to 4A ROP stage occurred 1 week later. Both eyes were retreated 1 week later with intravitreal ranibizumab and laser photocoagulation. Treatment resulted in ROP regression in both cases. There were no signs of systemic or ocular adverse side effects.

Conclusion

The cases presented show that combination therapy of indirect laser photocoagulation and intravitreal ranibizumab can be effective in the management of aggressive posterior ROP. Further investigation on anti-VEGF safety in premature infants is necessary. Additional studies are needed to define the role of anti-VEGF in ROP treatment.Key Words: Retinopathy of prematurity, Laser photocoagulation, Ranibizumab, Anti-VEGF therapy

Effect of anti-VEGF treatment on retinopathy of prematurity in Zone II Stage 3+

AIM: To evaluate the effect of intravitreal ranibizumab injection for retinopathy of prematurity (ROP) in Zone II Stage 3+. METHODS: Data was collected for ROP patients with Zone II Stage 3+ who received intravitreal ranibizumab injections between October 2014 and Janu-ary 2017 at the Department of Ophthalmology in our hospital. No prior laser or other intravitreal treatment was done. Prior to the intervention and at each follow-up visit, fundus examination was performed. Gestational age at birth, sex, birth weight, ROP zone, ROP stage, post menstrual age (PMA) at treatment, and follow-up pe-riod were recorded. The final clinical status of the retina was evaluated for each patient. The primary outcome mea-sures included ROP recurrences requiring re-treatment, complete or incomplete peripheral vascularization. RESULTS: Eighty-six eyes of 46 premature infants with Zone II Stage 3+ ROP were enrolled in the study. The mean gestational age at birth was 28.18±1.67 (range: 25 to 33)wk and the mean birth weight was 1070.57±226.85 (range: 720.00 to 1650.00) g. The mean PMA at treatment was 38.32±2.99 (range: 32.29 to 46.00)wk. Seventy-one eyes (82.56%) were treated success-fully with intravitreal ranibizumab as monotherapy. Fifteen eyes (17.44%) developed recurrent disease. The mean interval between the treatment and retreatment was 5.96±3.22 (range: 1.86 to 11.71)wk. All eyes vascularized into zone III at the end of the study and among them 62 eyes (72.09%) achieved complete vascu-larization. CONCLUSION: Intravitreal ranibizumab injection is an effective treatment in Zone II Stage 3+ ROP patients. More patients with longer follow-up duration are necessary to confirm the safety and efficacy of this treatment.     

Clinical features and treatment outcomes of intraocular lymphoma: a single-center experience in China

AIM:To investigate the clinical manifestations,diagnostic approaches,treatments,and outcomes of intraocular lymphoma.METHODS:In this retrospective study,16 patients(28 eyes)with intraocular lymphoma were recruited in the Department of Ophthalmology,Peking Union Medical College Hospital,from 2004 to 2019.All patients underwent comprehensive ophthalmic examinations.Vitreous specimens of 13 patients were sent for cytopathology examination and other adjunctive diagnostic procedures.Three patients were diagnosed with intraocular lymphoma according to analysis of the histopathological results of systemic lymphoma by one clinician.Twenty-three eyes were treated with intravitreal administration of methotrexate,4 eyes could not receive ocular treatment due to life-threatening lymphoma,and 1 eye did not require ocular treatment because the fundus lesions regressed after systematic chemotherapy.RESULTS:In 28 eyes,25 eyes were diagnosed with vitreoretinal lymphoma,and 3 eyes were diagnosed with ciliary body lymphoma,all of which were non-Hodgkin diffuse large B cell lymphomas.The final visual acuity improved in 15 eyes(54%),remained unchanged in 5 eyes(18%),and decreased in 8 eyes(29%).Anterior segment inflammation disappeared or reduced in 8 and 5 eyes,respectively;and 15 eyes had no anterior segment reaction.Twenty eyes had mild vitreous opacity,1 eye had mild vitritis,and 7 eyes had pars plana vitrectomy combinedwith silicone oil tamponade.Fundus lesions disappeared in 9 eyes and were relieved in 5 eyes;4 eyes showed no changes,and the remaining 10 eyes’fundus were normal.CONCLUSION:The clinical manifestations of intraocular lymphoma are diverse,and the misdiagnosis rate is high.Cytopathological analysis of vitreous is one of the gold standards for the diagnosis.Immunohistochemistry,gene rearrangement and flow cytometric immunophenotypic analysis can improve the diagnostic rate.Ocular chemotherapy or radiotherapy regimens may preserve visual acuity,and a multidisciplinary team can provide individualized treatment for the patients.

目的:观察早产儿视网膜病变(retinopathy of prematurity,ROP)激光光凝术后嵴前部分无血管化区的临床转归,为ROP的临床治疗提供依据.方法:前瞻性随访观察2014-06/2016-06由我院ROP筛查协作组在门诊以及NICU床旁筛查发现并进行视网膜激光光凝治疗的患儿186例372眼,激光光凝术后嵴前存在部分无血管区的患儿26例32眼,其中男17例18眼,女9例14眼,平均出生胎龄(29.4±0.4)周,平均出生体质量1222.8±70.3g,阈值前1型10例12眼,阈值期12例14眼、急性进展性后极部型4例6眼,分别于激光术后1、3、8、12 wk行Retcam眼底照相复查,观察病变嵴、嵴前无血管区以及附加病变的消退情况.随访中如发现病变嵴或附加病变加重,则给予补充视网膜激光光凝或行玻璃体腔抗VEGF治疗,直至病变嵴和附加病变完全消退,病情稳定.结果:患儿26例均在激光术后1 wk复查时发现病变嵴前无血管区,但附加病变减轻,病变嵴由3期向2期、1期消退,阈值前1型消退最明显;3 wk复查时27眼(84%)病变嵴为1期或不明显、无血管区逐渐缩小,视网膜血管向周边发育;5眼(16%)无血管区缩小不显著,附加病变(+~++),病变嵴3~4期、或伴有出血,其中3眼(9%)为阈值期病变患儿,2眼(6%)为急性进展性后极部型患儿,遂及时给予补充视网膜光凝;8 wk复查,未补充视网膜光凝的27眼嵴前无血管区已血管化,嵴及附加病变消退;补充光凝中3眼(9%)病情得到控制、稳定,其中阈值期2眼、急性进展性后极部型1眼,2眼(6%)嵴上新生血管消退不明显、附加病变依然存在,其中阈值期1眼、急性进展性后极部型1眼,故给予玻璃体腔抗VEGF治疗,12 wk复查时见附加病变、病变嵴消退,视网膜血管向颞侧走形稍僵直.结论:视网膜激光光凝是ROP治疗的有效方法,光凝术后嵴前部分无血管区多可自行发育完善.对于少数激光术后病情活动的阈值期及急性进展性后极部型嵴前部分无血管区需及时补充激光光凝治疗,必要时可联合玻璃体腔抗VEGF治疗.
