  • A single-center retrospective clinical study on comprehensive treatment for 157 patients with retinoblastoma

    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.

  • Retrospective clinical study on the comprehensive treatment of retinoblastoma

    ObjectiveTo observe the curative effect, survival rate, enucleation rate and pathological characteristics of retinoblastoma (RB) in children.MethodsRetrospective clinical study. From March 1999 to December 2018, a total of 313 patients (445 eyes) with RB diagnosed in Ophthalmology Department of Peking University People’s Hospital were enrolled in the study. Among them, 175 were male (55.9%), 138 were female (44.1%); 181 were monocular and 132 were binocular. The international standard of intraocular RB staging (IIRC) was 6, 13, 6, 52, 227 and 9 patients of A, B, C, D, E and extraocular stages respectively. Among the 313 patients, 245 patients were confirmed to the survivance, of which 22 cases (9.0%, 22/245) died. Among 445 eyes, 330 eyes definitely whether or not were enucleated; 184 eyes had definite IIRC stage, eye examination results, definite treatment plan and times before enucleation and definite pathological tumor node metastasis stage after operation. The basic information, demographic characteristics, clinical information, enucleation and treatment plan, pathological and immunohistochemical results were recorded. Binary logistic regression was used to analyze the risk factors of high risk pathological features (HRF) and prognosis in patients with RB.ResultsFrom 1999 to 2018, the survival rate of 245 patients was increased from 82.6% to 96.3% year by year; the enucleation rate of 330 eyes with final enucleation was reduced from 68.8% to 58.3% year by year. The rate of enucleation in stage D and stage E decreased from 83.3% and 100% before 2005 to 37.5% and 85.4% after 2014, respectively. Monocular disease (β=-1.551, P=0.005), stage D, stage E and extraocular stage in IIRC stage (P<0.005) were the independent risk factors of RB enucleation, while the protective factors were Interventional chemotherapy of ophthalmic artery (IAC) (β=-0.877, P<0.001). HRF was found in 51 eyes (27.7%). Age of onset (β=0.019, P=0.016) and glaucoma (β=0.816, P=0.050) were independent risk factors for HRF in RB pathology, while IAC treatment was the protective factor for enucleation (β=21.432, P<0.001).ConclusionsAfter comprehensive treatment, the general trend of RB enucleation rate is gradually decreasing. IAC treatment can reduce the enucleation rate of stage D and E. The older age of onset and glaucoma stage are the independent risk factors of HRF, and IAC can reduce the risk factors of HRF.

  • Digital subtraction angiography characteristics of ophthalmic artery and its main branches in ischemic cerebrovascular disease

    Objective To observe the digital subtraction angiography (DSA) characteristics of ophthalmic artery and its main branches in ischemic cerebrovascular disease (ICVD). Methods The internal carotid arteries, external carotid arteries and ophthalmic arteries of 32 ICVD patients were examined for DSA. The characteristics of ophthalmic artery origin, trail and main branches were observed. Results Among 64 carotid arteries of 32 patients, there was one carotid artery with internal occlusion, there was no severe stenosis in the other 63 carotid arteries. The 63 ophthalmic arteries originated all from supraclinoidal and ophthalmic segments of internal carotid arteries. 58 ophthalmic arteries were single branch from the internal carotid artery. 5 ophthalmic arteries had 2 branches, one come from the internal carotid artery, the other come from the middle meningeal artery (external carotid artery branch ) in 4 cases or from the anterior cerebral artery (carotid artery branch) in 1 case. The main branches of ophthalmic artery included central retinal artery, posterior ciliary artery, lacrimal gland artery, ocular muscular artery; anterior ethmoid artery, posterior ethmoid artery, supraorbital artery, dorsal nasal artery, supratrochlear artery and eyelid artery. The beginning point of each branches were variable. Conclusions Ophthalmic arteries of ICVD patients primary arise from the internal carotid artery. It most often appears as single branch and occasionally as double branches. The beginning points of major branches of ophthalmic artery are variable.

  • Relationship between age-adjusted Charlson comorbidity index and ischemic stroke in patients with ophthalmic artery occlusion or retinal artery occlusion

    Objective To investigate the relationship between age-adjusted Charlson comorbidity index (aCCI) and ischemic stroke in patients with ophthalmic artery occlusion (OAO) or retinal artery occlusion (RAO). MethodsA single center retrospective cohort study. Seventy-four patients with OAO or RAO diagnosed by ophthalmology examination in Shenzhen Second People's Hospital from June 2004 to December 2020 were included in the study. The baseline information of patients were collected and aCCI was used to score the patients’ comorbidity. The outcome was ischemic stroke. The median duration of follow-up was 1 796.5 days. According to the maximum likelihood ratio of the two-piecewise COX regression model and the recursive algorithm, the aCCI inflection point value was determined to be 6, and the patients were divided into low aCCI group (<6 points) and high aCCI group (≥6 points). A Cox regression model was used to quantify the association between baseline aCCI and ischemic stroke. ResultsAmong the 74 patients, 53 were males and 21 were females, with the mean age of (55.22±14.18) (19-84) years. There were 9 patients of OAO and 65 patients of RAO. The aCCI value ranges from 1 to 10 points, with a median of 3 points. There were 63 patients (85.14%, 63/74) in the low aCCI group and 11 patients (14.86%, 11/74) in the high aCCI group. Since 2 patients could not determine the time from baseline to the occurrence of outcome events, 72 patients were included for Cox regression analysis. The results showed that 16 patients (22.22%, 16/72) had ischemic stroke in the future. The baseline aCCI in the low aCCI group was significantly associated with ischemic stroke [hazard ratio (HR)=1.76, 95% confidence interval (CI) 1.21-2.56, P=0.003], and for every 1 point increase in baseline aCCI, the risk of future ischemic stroke increased by 76% on average. The baseline aCCI in the high aCCI group had no significant correlation with the ischemic stroke (HR=0.66, 95%CI 0.33-1.33, P=0.247). ConclusionsaCCI score is an important prognostic information for patients with OAO or RAO. A higher baseline aCCI score predicts a higher risk of ischemic stroke, and the association has a saturation effect.

  • Preliminary results of magnetic resonance angiography of ophthalmic artery in diabetic retinopathy

    ObjectiveTo observe the characteristics of magnetic resonance angiography of (MRA) ophthalmic artery in patients with diabetic retinopathy (DR).MethodsA total of 36 eyes of DR patients (DR group) diagnosed by clinical examination were included in the study. Among them, there were 42 eyes in 21 males and 15 eyes in 15 females. The average age was 55.2 years old. The average duration of diabetes was 7.56 years. All eyes were examined by MRA and fluorescein fundus angiography (FFA) in the ophthalmic artery. At the same time, 24 eyes of 12 patients were examined by computed tomography angiography (CTA). Twenty-two healthy volunteers with age and gender matching were selected as the control group. Among them, there were 13 males and 9 females. All patients underwent MRA examination of the ophthalmic artery; at the same time, 5 eyes of 5 eyes were examined by CTA. MRA and CTA were classified into three grades according to the development condition and shape change of the ophthalmic artery. 0 grade : no abnormality; grade Ⅰ: mild lesion; grade Ⅱ: obvious lesion. According to the results of FFA examination, it was divided into no obvious disease stage, background stage, proliferative stage, proliferative stage. The morphological features of the MRA of the ophthalmic artery in the DR group and the control group were compared. The relationship between the MRA grading of the ophthalmic artery and the FFA staging was observed in the DR group. The consistency analysis between the MRA and CTA grades of the ophthalmic artery in the DR group was performed by Kappa test; the relationship between the MRA grade and the FFA staging of the ophthalmic artery was analyzed by Spearson correlation analysis of the same data with two-way ordered attributes.ResultsIn 44 eyes of the control group, the MRA in grade 0 and Ⅰ of the ophthalmic artery were 41 and 3 eyes, respectively; all eyes of the CTA examination of the ophthalmic artery were grade 0. In 72 eyes of the DR group, the MRA in grade 0, Ⅰ, and Ⅱ of the ophthalmic artery were 28, 28, and 16 eyes, respectively. Among the 24 eyes examined by CTA, there were 13, 6, and 5 eyes in grade 0, Ⅰ, and Ⅱ, respectively. In the DR group, the classification of MRA and CTA of the ophthalmic artery was highly consistent (Kappa value = 0.86). There were significant differences in the number of eyes with different grades of MRA in the DR group and the control group (Z=-5.74, P=0.000). In 72 eyes of the DR group, there were 8, 12, 22, and 30 eyes in no obvious disease stage, background stage, proliferative stage, and proliferative stage, respectively. Correlation analysis showed that there was a significant correlation between MRA grading and FFA staging in the DR group (r=0.405, P=0.000).ConclusionsMRA can show the changes of ophthalmic artery morphology and reflect DR staging to a certain extent. It has a high consistency with FFA vascular changes.

  • Efficacy and safety of intra-arterial thrombolysis for retinal artery occlusion based on the green channel for eye stroke

    Objective To explore the short-term efficacy and safety of intra-arterial thrombolysis (IAT) in the treatment of retinal artery occlusion (RAO) with the assistance of the rescue green channel in the eye stroke center. Methods A prospective, interventional, single-center study. Thirty-eight eyes from 38 RAO patients who received IAT treatment in Guangdong Provincial People’s Hospital were enrolled. All the patients were rescued via the green channel in our eye stroke center. Data from comprehensive ocular examinations including best-corrected visual acuity (BCVA) and optical coherence tomography angiography (OCTA) were collected. BCVA was measured with Snellen chart and converted to the logarithmic minimum angle of resolution (logMAR) unit for statistical analysis. RTVue XR OCTA was used to measure vascular densities (VD) of the superficial capillary plexus (SCP), deep capillary plexus (DCP) and radial peripapillary capillary (RPC), and central retinal thickness (CRT). All RAO eyes attempted IAT treatment and 34 eyes were successful. Four eyes failed to complete IAT because of the occlusion of internal or common carotid arteries on the same side with the RAO eyes. Ocular examinations in post-operative 1-3 days were performed with the same devices and methods as those before surgery. Parameters measured before and after surgery include BCVA, VD of SCP, DCP, RPC, and CRT. Data of the green channel collected include the time intervals from onset of RAO to first presentation in local hospitals, and from onset of RAO to our eye stroke center. Comparisons of VD and CRT between the RAO eyes and contralateral healthy eyes were performed with independent samples Mann-Whitney U test; comparisons of VD and CRT in RAO eyes before and after IAT surgery were performed with paired samples Wilcoxon Rank Sum test. Results Among the 34 RAO patients who had successful IAT surgery, 18 (52.9%, 18/34) were males and 16 (47.1%, 16/34) were females; the mean age was (51.0±12.9) years old. There were 30 and 4 eyes diagnosed as central RAO and branch RAO respectively. The logMAR BCVA before and after IAT surgery was 2.52±0.61 and 2.18±0.85 respectively, and the difference was statistically significant (Z=-3.453, P=0.002). Before surgery, VD of SCP, DCP and RPC were significantly decreased and CRT was significantly increased in the affected eye compared with the contralateral healthy eyes, with the statistical significance (P<0.001). Compared with those before surgery, the VD of SCP and DCP were significantly improved after surgery (Z=-2.523, -2.427; P=0.010, 0.014), while there was no difference in VD of RPC and CRT (Z=-1.448, -1.454; P=0.150, 0.159). The time interval between onset of RAO and first visit to the hospital was (6.56±6.73) hours; the time interval between onset of RAO and the arrival at our hospital was (24.11±19.90) hours. No cerebral stroke was observed in the early post-operative period and no cerebrocardiovascular events were observed later. he time interval between onset of RAO and the arrival at our hospital was (24.11±19.90) hours. No cerebral stroke was observed in the early post-operative period and no cerebrocardiovascular events were observed later. Conclusions The short-term efficacy and safety of IAT in the treatment of RAO were satisfactory. The rescue time window might be prolonged.

  • Effect of urokinase thrombolytic therapy for optic artery and retinal artery occlusion caused by facial microinjection with hyaluronic acid and spontaneous retinal artery occlusion

    ObjectiveTo compare the clinical effects of urokinase thrombolytic therapy for optic artery occlusion (OAO) and retinal artery occlusion (RAO) caused by facial microinjection with hyaluronic acid and spontaneous RAO.MethodsFrom January 2014 to February 2018, 22 eyes of 22 patients with OAO and RAO caused by facial microinjection of hyaluronic acid who received treatment in Xi'an Fourth Hospital were enrolled in this retrospective study (hyaluronic acid group). Twenty-two eyes of 22 patients with spontaneous RAO were selected as the control group. The BCVA examination was performed using the international standard visual acuity chart, which was converted into logMAR visual acuity. FFA was used to measure arm-retinal circulation time (A-Rct) and filling time of retinal artery and its branches (FT). Meanwhile, MRI examination was performed. There were significant differences in age and FT between the two groups (t=14.840, 3.263; P=0.000, 0.003). The differecens of logMAR visual acuity, onset time and A-Rct were not statistically significant between the two groups (t=0.461, 0.107, 1.101; P=0.647, 0.915, 0.277). All patients underwent urokinase thrombolysis after exclusion of thrombolytic therapy. Among the patients in the hyaluronic acid group and control group, there were 6 patients of retrograde ophthalmic thrombolysis via the superior pulchlear artery, 6 patients of retrograde ophthalmic thrombolysis via the internal carotid artery, and 10 patients of intravenous thrombolysis. FFA was reviewed 24 h after treatment, and A-Rct and FT were recorded. Visual acuity was reviewed 30 days after treatment. The occurrence of adverse reactions during and after treatment were observed. The changes of logMAR visual acuity, A-Rct and FT before and after treatment were compared between the two groups using t-test.ResultsAt 24 h after treatment, the A-Rct and FT of the hyaluronic acid group were 21.05±3.42 s and 5.05±2.52 s, which were significantly shorter than before treatment (t=4.569, 2.730; P=0.000, 0.000); the A-Rct and FT in the control group were 19.55±4.14 s and 2.55±0.91 s, which were significantly shorter than before treatment (t=4.114, 7.601; P=0.000, 0.000). There was no significant difference in A-Rct between the two groups at 24 h after treatment (t=1.311, P=0.197). The FT difference was statistically significant between the two groups at 24 h after treatment (t=4.382, P=0.000). There was no significant difference in the shortening time of A-Rct and FT between the two groups (t=0.330, 0.510; P=0.743, 0.613). At 30 days after treatment, the logMAR visual acuity in the hyaluronic acid group and the control group were 0.62±0.32 and 0.43±0.17, which were significantly higher than those before treatment (t=2.289, 5.169; P=0.029, 0.000). The difference of logMAR visual acuity between the two groups after treatment was statistically significant (t=2.872, P=0.008). The difference in logMAR visual acuity before and after treatment between the two groups was statistically significant (t=2.239, P=0.025). No ocular or systemic adverse reactions occurred during or after treatment in all patients. ConclusionsUrokinase thrombolytic therapy for OAO and RAO caused by facial microinjection with hyaluronic acid and spontaneous RAO is safe and effective, with shortening A-Rct, FT and improving visual acuity. However, the improvement of visual acuity after treatment of OAO and RAO caused by facial microinjection with hyaluronic acid is worse than that of spontaneous RAO.
