【In Press】Effect of anti-VEGF treatment on retinopathy of prematurity in Zone II Stage 3+

AIM: To assess the effect of intravitreal ranibizumab injection for retinopathy of prematurity (ROP) in Zone II Stage 3+. METHODS: Data was collected from ROP patients with Zone II Stage 3+ who had intravitreal ranibizumab injections between October 2014 and January 2017 at the department of Ophthalmology in our hospital. No prior laser or other intravitreal therapy was done. Fundus examination was performed prior to the intervention and at each follow-up visit. Gestational age at birth, birth weight, sex, ROP zone, ROP stage, post menstrual age (PMA) at treatment, and follow-up period were recorded. The final clinical status of the retina was noted for each patient. The primary outcome measures 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±1.67wk (range: 25 to 33wk) and the mean birth weight was 1070.57±226.85 g (range: 720.00 to 1650.00 g). The mean PMA at treatment was 38.32±2.99wk (range: 32.29 to 46.00wk). Seventy-one eyes (82.56%) were treated successfully with intravitreal ranibizumab as monotherapy. Fifteen eyes (17.44%) developed recurrent disease. The mean interval between the treatment and retreatment was 5.96±3.22wk (range: 1.86 to 11.71wk). All eyes vascularized into zone III at the end of the study and among them 62 eyes (72.1%) achieved complete vascularization. CONCLUSION: Intravitreal ranibizumab injection is an effective treatment in patients with zone II stage 3+ ROP. More patients with longer follow-up duration are mandatory 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.     

Effects of ranibizumab on very low birth weight infants with stage 3 retinopathy of prematurity: A preliminary report

Background/PurposeTo report the effects of ranibizumab on very low birth weight (VLBW) infants with retinopathy of prematurity (ROP).MethodsA retrospective, noncomparative, consecutive, interventional case series was conducted. Patients with stage 3 ROP were identified and evaluated from August 2011 to February 2012. All patients with ROP received one intravitreal ranibizumab injection (0.25 mg/0.025 mL) under topical anesthesia as the initial treatment.Main outcome measures: Regression of ROP and the complications associated with the intravitreal ranibizumab injection.ResultsA total of 23 eyes of 12 patients (four boys and eight girls) were included in this study. All of the patients had a history of supplemental oxygen and mechanical ventilation use. The mean gestational age was 26.33 ± 2.06 weeks (range: 24–30 weeks), and the mean birth weight was 821.58 ± 297.63 g (range: 507–1480 g). The mean postmenstrual age during the intravitreal administration of ranibizumab injection was 35.08 ± 2.07 weeks (range: 32–39 weeks), and the mean follow-up period was 5.83 ± 1.64 months (range: 3–8 months). All eyes received one intravitreal ranibizumab injection (0.25 mg/0.025 mL) as the primary therapy. None of the eyes needed conventional laser photocoagulation or cryotherapy as adjuvant therapy and no systemic complications were noted. No cataracts, endophthalmitis, or retinal detachment occurred postoperatively. Preretinal hemorrhages were found in four eyes of three patients (17.39%), but all were absorbed without sequelae.ConclusionIntravitreal ranibizumab injections seem to be effective and well tolerated in VLBW infants with stage 3 ROP. Only self-limited preretinal hemorrhages were noted, and no short-term systemic or major ocular side effects were identified.     

Efficacy evaluation of intravitreal ranibizumab therapy for three types of retinopathy of prematurity

AIM: To evaluate efficacy of intravitreal ranibizumab (IVR) therapy for aggressive posterior retinopathy of prematurity (ROP), threshold ROP disease and type 1 pre-threshold ROP. METHODS: A retrospective analysis was performed on 40 patients (76 eyes) who had IVR as the primary treatment for ROP from April 2017 to January 2018. According to disease pathogenic features, the 76 eyes were divided into three groups: aggressive posterior ROP (AP-ROP) group (16 eyes), threshold ROP group (28 eyes) and type 1 pre-threshold ROP group (32 eyes). The characteristics of patients and lesions situation before the first intravitreal injection, and posttreatment fundus outcomes determined by wide-angle RetCam fundus imaging were recorded. RESULTS: The birth weight and postmenstrual age of first IVR treatment in AP-ROP, threshold ROP, and type 1 pre-threshold ROP groups were significant difference (1087.50±246.78, 1103.75±168.30, 1257.03±210.82 g, P=0.005; 34.50±1.46, 36.89±2.97, 36.50±2.36wk, P=0.008), while the gestational age was not difference (28.00±2.00, 28.54±1.90, 28.59±1.43wk, P=0.510). The retina hemorrhage ratio (with/without: 14/2, 8/20, 5/27), iris neovascularization or vascular engorgement ratio (with/without: 12/4, 11/17, 6/26), and the zone I (inside/outside: 16/0, 2/26, 5/27) in AP-ROP, threshold ROP, and type 1 pre-threshold ROP group were difference significantly (all P<0.05). The regression rates were 37.5%, 92.86%, and 100%, and the recurrence rates were 62.5%, 7.14%, and 0 in AP-ROP, threshold ROP, and type 1 pre-threshold ROP group, respectively (both P<0.05). The recurrence eyes were cured by secondary IVR or retinal laser photocoagulation. CONCLUSION: IVR is an effective treatment for all types of ROP. The regression of AP-ROP is significantly lower than type 1 pre-threshold and threshold disease. Birth weight, retinal hemorrhage, iris neovascularization or vascular engorgement and lesions located in zone I may be associated with AP-ROP recurrence and retreatment, which should be noted in follow-up.

Comparison of structural outcome between intravitreal bevacizumab and laser treatment for type 1 retinopathy of prematurity after long-term follow-up

Background:To compare the structural outcome of intravitreal bevacizumab (IVB) and laser treatment for type 1 retinopathy of prematurity (ROP). Methods: This is a retrospective comparative study. From December 2002 to April 2009, patients with type 1 ROP according to criteria of Early Treatment of Retinopathy of Prematurity (ETROP) study were treated by peripheral retinal diode laser photocoagulation in nearly confluent pattern. From May 2009 to January 2015, we performed IVB for patients with type 1 ROP. The patients were closely followed until disappearance of retinal neovascularization in the laser group and regression of avascular zone in the bevacizumab group. The demographical data, postmenstrual age (PMA) for treatment, and fundus ifndings were recorded by chart review. The difference between laser and bevacizumab groups was compared by Studentt-test and Fisher exact test. Results: We collected 43 patients (86 eyes) with type 1 ROP, including 30 male and 13 female infants. Their mean gestation age and birth body weight (BBW) were 27.5 weeks and 1,034 gm. Zone I and zone II disease were found in 8 and 35 patients. The mean PMA for treatment was 37.3 weeks. The mean follow-up period was 54.4 months. Laser treatment was administered in 26 patients, and bevacizumab injection for 17 infants. Single session of laser was performed in all patients of laser group without recurrence of retinal neovascularization. Complete regression of ROP was found in 15 infants of bevacizumab group following the ifrst IVB. Four eyes in two patients (2/17, 11.7%) had recurrence of ROP and received additional injections and adjuvant laser treatment. There was no unfavorable anatomical results such as retinal detachment or macular ectopia or complications such as cataract or endophthalmitis in either bevacizumab or laser management. Conclusions: Laser therapy and IVB were both effective treatments for type 1 ROP to cause favorable anatomical outcomes. Single session of laser ablation in nearly conlfuent pattern was sufifcient for complete regression of ROP in laser group. Single IVB was appropriate for managing most of cases with ROP in bevacizumab group, but a small proportion (nearly one tenth) of them had recurrent episodes requiring adjuvant therapies.

结论：激光光凝术联合玻璃体腔注射低剂量雷珠单抗治疗急进型后极部ROP安全、有效。     

Effects of three consecutive monthly intravitreal injection of ranibizumab for polypoidal choroidal vasculopathy in Korea

AIM: To evaluate the efficacy and safety of three consecutive monthly injections of intravitreal ranibizumab for the treatment of polypoidal choroidal vasculopathy (PCV) in Korea. METHODS: A retrospective chart review of 25 patients (27 eyes) with PCV was conducted. Patients received three initial monthly intravitreal injections (0.5 mg) of ranibizumab and were monitored monthly for 12mo between January 2010 and October 2011. Reinjection of ranibizumab after three initial monthly loading was administered on an as-needed basis, guided by the optical coherence tomography (OCT), fluorescein angiography (FA) and indocyanine green angiography (ICGA). The main outcomes were the changes of the mean best corrected Snellen visual acuity (VA), central macular thickness (CMT) by OCT, the changes of polyps and branching vascular network by FA and ICGA, and total number of injections received by patients during the 12mo. RESULTS: The mean best corrected Snellen visual acuities at baseline, 1, 3, 6 and 12mo after primary injection were 0.77±0.59, 0.76±0.53, 0.70±0.47, 0.63±0.43, 0.61±0.43, 0.62±0.42 logMAR, respectively, and showed significant improvement at 3, 6, 12mo (P=0.003, P=0.002, P=0.018, Wilcoxon signed-rank test). The mean CMT at baseline, 1, 2, 3, 6, and 12mo was 312.41±66.38 μm, 244.59±71.47 μm, 232.32±69.41 μm, 226.69±69.03 μm, 228.62±37.07 μm, 227.59±51.01 μm respectively, and showed significant reduction (all P<0.001, Wilcoxon signed-rank test). Polypoidal lesions resolved on ICGA in 3 eyes (11.1%) and a branching vascular network remained in all 24 eyes (88.9%). A total of 106 injections were given in the 12-month period, which equaled to a mean of 3.92 (range, 3-6) times. Sixteen of the 27 treated eyes had additional 1.56±0.91 injections. The others (11 eyes) had just 3 consecutive injections. CONCLUSION: An initial loading dose of three monthly ranibizumab injections is a safe and effective method in treating PCV, with visual and anatomical improvement over one year follow-up.     

Staged lensectomy and vitrectomy in the management of stage 5C retinopathy of prematurity with corneal opacification: long-term follow up

AIM: To verify the feasibility and safety of staged lensectomy and vitrectomy in stage 5C retinopathy of prematurity (ROP) with corneal opacification. METHODS: This was a retrospective, interventional, consecutive case series. Twenty-two eyes of 18 stage 5C ROP patients with corneal opacification were included. Regular combined lensectomy and vitrectomy were not prescribed due to the invisible fundus. Staged lensectomy and posterior vitrectomy were performed. The anatomical and visual outcomes were reviewed at the final follow-up visit. RESULTS: The mean gestational age of ROP patients was 29.3±1.6wk (range: 27-32wk), comprising 8 males and 10 females. The average birth weight was 1363.0±300.0 g. All the eyes had corneal opacity and flat or disappeared anterior chambers pre-operatively. Two eyes had complicated cataract and 7 eyes had retrolental fibroplasia. Six eyes had posterior pupillary synechiae or membranes. Seven (31.8%) eyes had vascularly active retinas. The average interval between two procedures was 6.8±4.6mo (2.5-18.5mo). After surgeries, all the patients had normal anterior chambers. Fourteen eyes had clear corneas. The intraocular pressure of 3 eyes with glaucoma was controlled by medication. Two eyes had ocular phthisis. The retina was reattached in 3 eyes and partially attached in 11 eyes. Visual acuity ranged from no light perception to hand motion. CONCLUSION: Staged lensectomy and vitrectomy are procedures that can halt progression to further complications and preserve some useful eyesight in stage 5C ROP patients with corneal opacification. The earlier the lensectomy is performed, the better the prognosis is.
