ObjectiveTo observe the clinical characteristics of rhegmatogenous retinal detachment (RRD) secondary to conservative therapy in retinoblastoma (RB) patients.MethodsA retrospective study. From July 2013 to May 2017, 20 RRD patients (20 eyes) of 456 RB patients (573 eyes) treated in Xinhua Hospital of Shanghai Jiao Tong University School of Medicine were included in the study. Eleven patients (11 eyes) were boy and 9 patients (9 eyes) were girls. Thirteen patients demonstrated bilateral RB and 7 patients had unilateral RB. Average age when diagnosed with RB was 25 months. International Classification of Retinoblastoma groups were C in 1 eye, D in 17 eyes, and E in 2 eyes. These patients received intra-arterial chemotherapy (17 eyes), intravenous chemotherapy (11 eyes), intravitreal chemotherapy (8 eyes), laser (14 eyes) and/or cryotherapy (5 eyes). Twelve patients (12 eyes) received vitreoretinal surgery including vitrectomy (6 eyes) and scleral buckling (7 eyes). The mean follow-up was 39 months. Fundus examination was performed under general anesthesia during comprehensive treatment and follow-up. The time interval of fundus examination varied from 1 to 6 months depending on the stability of the tumor.ResultsRRD was noted in 20 eyes (3.5%) with RB. Retinal hole was found in 15 eyes (75%). The cause of RRD was atrophic hole in calcified tumor (6 eyes, 30%), cryotherapy-related hole (5 eyes, 25%) and laser-related hole (9 eyes, 45%). Multiple atrophic hole in calcified tumor was noted in 3 eyes. Size of hole smaller than 2 DD was noted in 8 eyes (53%), and larger than 2 DD was noted in 7 eyes (47%). Holes were in posterior (3 eyes), equator (2 eyes) and periphery (10 eyes). Severe proliferated was noted in 1 eye. No tear was found. No bulbar retinal detachment and choroidal detachment was noted. Among 12 eyes who underwent vitreoretinal surgery, reattachment was achieved in 9 eyes (75%). No metastasis was noted.ConclusionsCalcified regression of tumor, cryotherapy and laser were main reasons of RRD. Most of the holes are small in diameter and located in the periphery.
ObjectiveTo evaluate the functional and anatomical outcomes of autologous single retinal pigment epithelium (RPE) transplantation for severe obsolete submacular hemorrhage (SMH) in late age-related macular degeneration (AMD). MethodsA retrospective clinical study. From January 2012 to December 2015, 11 patients with AMD (11 eyes) with obsolete SMH who were diagnosed and treated by pars plana vitrectomy (PPV) combined with autologous RPE transplantation at the Department of Ophthalmology, Xin Hua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were included. Among them, there were 9 eyes in 9 males and 2 eyes in 2 females. All the eyes underwent the examinations of best corrected visual acuity (BCVA) and optical coherence tomography; 4 eyes underwent macular fixation function (MAIA) at the same time. The BCVA examination was carried out using the international standard visual acuity chart, which was converted into logarithm of the minimum angle of resolution (logMAR) visual acuity during statistics. All eyes were treated with PPV combined with autologous single-layer RPE transplantation or autologous RPE-choroidal full-thickness transplantation, and were divided into S group and C group, with 5 and 6 eyes respectively. The differences of age (t=－0.363), gender composition ratio (χ2=0.549), course and thickness of SMH (t=0.118, 0.231), average times of anti-vascular endothelial growth factor drug treatments (t=0.129), times of PPV (t=－0.452) between the two groups were not statistically significant (P>0.05). The follow-up period was 6-40 months after the operation, and the BCVA, MAIA, graft status and complications of the eyes after the operation were observed. The comparison of continuous variables between groups was performed by independent-sample t test; the comparison of categorical variables was performed by χ2 test. ResultsAt the last follow-up, the average logMAR BCVA of the eyes in group S and C were 1.62±0.34 and 1.03±0.20, respectively; group C was better than group S, however, the difference was not statistically significant (t=1.532, P=0.160). There were 4 eyes (80%, 4/5) and 6 eyes (100%, 6/6) in S group and C group with BCVA better than preoperative, the difference was no statistical significance (χ2=0.677, P=0.895). There were 2 (40%, 2/5) and 3 (50%, 3/6) eyes with logMAR BCVA better than 1.0 in S group and C group, and the difference was not statistically significant (χ2=0.572, P=0.423). After the operation, 6 eyes of grafts were in good condition and 5 eyes were in poor condition; the BCVA of grafts in good condition was significantly higher than that of poor condition, the difference was statistically significant (t=4.894, P=0.001). Among the 4 eyes that underwent MAIA examination, 2 eyes were unstable and diffusely fixed on the graft; the fixation point was located at the normal retina adjacent to the graft area in 2 eyes. Secondary subretinal hemorrhage occurred in 3 eyes after the operation; the intraocular pressure was high in 1 eye after the operation. During the follow-up period, no intraocular infection, secondary retinal detachment, recurrent choroidal neovascularization or low intraocular pressure occurred in all eyes. ConclusionsBoth autologous single-layer RPE transplantation and autologous RPE-choroidal full-thickness transplantation can help stabilize or even improve the visual function of eyes with severe SMH secondary to advanced AMD. The visual acuity after surgery is closely related to the state of the graft.
ObjectiveTo evaluate the efficacy and safety of comprehensive treatment for retinoblastoma (RB). MethodsA retrospective clinical study. From January to December in 2019, 157 cases (203 eyes) of RB who were diagnosed by the Department of Ophthalmology of Xinhua Hospital and received comprehensive treatment were included in this study. Of cases, 76 were male, and 81 were female; 111 were unilateral, and 46 were bilateral. The medium of age at diagnosis was 20.1 months. All patients received treatment for the first time. Patients with intraocular tumors were divided into A-E stages, extraocular stage and distant metastasis according to international intraocular RB classification standard. The median follow-up time was 37.4 months. Clinical features, treatment, prognosis and ocular complications of all cases were recorded. ResultsAmong 157 cases (203 eyes), 137 cases (180 eyes) were in intraocular stage; 6, 14, 10, 98, and 52 of eyes were in A-E stages, respectively. Twelve cases (12 eyes) were in extraocular stage; 8 cases (11 eyes) were in distant metastasis stag; 8 cases died due to distant metastasis; 149 cases (94.9%, 149/157) survived; 48 eyes were enucleated, 34 of which underwent initial enucleation, and 14 eyes underwent enucleation after eye-preserving treatment. The overall global salvage rate was 155 eyes (76.4%,155/203), and that after eye-preserving treatment was 91.7% (155/169). Severer eye for bilateral cases was taken into account for statistic; 120 cases (120 eyes) received initial eye-preserving treatment. Among them, 36 and 84 eyes underwent initial intravenous chemotherapy (IVC) and initial intra-arterial chemotherapy (IAC), respectively. The enucleation of the two groups was 7(19.4%, 7/36), 7(8.3%, 7/84); 33 (91.7%, 33/36) and 33 (39.3%, 33/84) eyes received the second treatment, respectively. There was no significant difference in the rate of enucleation between the two treatments (χ2=2.037, P=0.154). There was significant difference in the percentage of secondary treatment (χ2=27.937, P＜0.001). Fifty-four eyes (45.0%, 54/120) stabilized after initial treatment, and 66 eyes (55.0%, 66/120) underwent secondary treatments due to poor response or tumor recurrence. For 66 eyes receiving secondary treatments, enucleation, IAC, intravitreous chemotherapy (IVitC), IAC combined with IVitC, and laser and/or cryotherapy was performed in 6, 18, 12, 13, and 17 eyes, respectively. The number of eyes of enucleation among the IAC, IVitC, and IAC combined with IVitC group was 5 (27.8%, 5/18), 1 (9.3%, 1/12), and 2 (15.4%, 2/13) eyes, which was no significantly different (χ2=2.001, P=0.368). Until the last follow-up, visual acuity outcomes were acquired in 148 eyes (72.9%, 148/203). Among them, 41, 53, 16 and 38 eyes had no light perception, light perception to finger counting, 20/400, and ≥20/200, respectively. In total, among 203 eyes, 121 eyes received IAC, of which 2, 4, and 1 eyes had optic disc atrophy, vitreous hemorrhage, and severe retinal-choroidal atrophy, respectively; 60 eyes received IVitC, of which one and one eye had vitreous hemorrhage and macular hemorrhagic necrosis, respectively. ConclusionsIn this study, the overall survival rate was 94.9% after comprehensive treatment and the rate of global salvage after eye-preserving treatment was 91.7%. The comprehensive treatment of retinoblastoma had a relatively high efficacy and safety.
