Abstract Introduction: To compare the results and complication rates of a 25-gauge pars plana vitrectomy (25g PPV) with gas tamponade for rhegmatogenous retinal detachment (RRD) between experienced and inexperienced surgeons.Materials and Methods: This is a retrospective comparative consecutive case series study of patients with uncomplicated RRD treated with 25g PPV with gas tamponade. Patients were divided into 2 groups: In Group 1 (ESG) the procedure was performed by an experienced vitreoretinal surgeon and in Group 2 (ISG) the procedure was performed by 2 inexperienced surgeons. Anatomical and functional results and complication rates were compared between the two groups.Results: 216 eyes were included in the study. In the ESG (106 eyes), the single operation success rate was 94.3%, and the final success rate was 100%. The mean best-corrected visual acuity (BCVA) improved from 0.38 decimal to 0.73 decimal. In the ISG (110 eyes), the single operation success rate was 93.6%, and the final success rate was 100.0%. The mean BCVA improved from 0.33 decimal to 0.74 decimal. The differences between groups were not statistically significant. There was no difference in complication rates between groups.Conclusions: A 25g PPV with gas tamponade for treatment of RRD yields excellent anatomical results and improvement in BCVA. With good technique and use of modern vitrectomy machines and instruments, even inexperienced surgeons can achieve high single operation success rate, suggesting a short learning curve. The complication rate is comparable between experienced and inexperienced surgeons.

<b><i>Purpose:</i></b> The aim of the study was to investigate the effect of tamponade duration on retinal changes induced by silicone oil (SO) in patients who underwent successful rhegmatogenous retinal detachment (RRD) surgery. <b><i>Methods:</i></b> Retrospective comparative case series of 68 patients who underwent SO tamponade for RRD. Patients were divided into 2 groups based on timing of SO removal: &#x3c;6 months (group 1, <i>n</i> = 34) versus ≥6 months (group 2, <i>n</i> = 34). The main outcome measure was the change in central macular, inner, and outer retinal layer thickness (CMT, IRLT, and ORLT) before and after SO removal (SOR). <b><i>Results:</i></b> The median tamponade duration was 4 [Clin Ophthalmol. 2016;10:471–6, Zhonghua Yan Ke Za Zhi. 1997 Jan;33(1):39–41] months in group 1 and 8 [Arch Ophthalmol. 1994 Jun;112(6):778–85, Retina. 2004 Dec;24(6):871–7] months in group 2 (<i>p</i> &#x3c; 0.001). The mean CMT significantly increased from 245.3 ± 22.2 μm and 238.8 ± 41.6 μm under SO to 281.3 ± 60.2 μm and 259.0 ± 43.5 μm after SOR in group 1 (<i>p</i> = 0.009) and in group 2 (<i>p</i> = 0.007), respectively. Automated segmentation measurement revealed a significant increase in mean IRLT (<i>p</i> = 0.014 and <i>p</i> = 0.013) but no change in mean ORLT (<i>p</i> = 0.080 and <i>p</i> = 0.257) in both groups. After adjustment, there was no difference between the 2 groups in terms of mean final CMT, IRLT, and ORLT and mean retinal thickness changes after SOR. There was also no correlation between the tamponade duration and macular microstructural changes or visual recovery. <b><i>Conclusion:</i></b> SO tamponade causes a thinning of all retinal layers, mainly affecting the inner retinal layer. However, these changes resolved following SO extraction and were not affected by longer tamponade duration.

Abstract Background: Dealing with chemotherapy-related cardiac dysfunction (CTRCD) remains a significant problem complicated by the difficulty in early detection of cardiotoxicity. Electrocardiogram (ECG) is expected to be the most realistic methodology due to lower cost-performance and non-invasiveness. We investigated the long-term visual fluctuations in the ECG waveforms in patients with chronic doxorubicin (DOX)-induced cardiotoxicity to identify ECG indices for the early detection of cardiotoxicity. Methods: We conducted a retrospective case series study by reviewing the medical records of 470 consecutive patients with malignant lymphoma who were treated with DOX at our institute between January 2010 and December 2017. Of them, 23 (4.9%) patients developed left ventricular dysfunction and were diagnosed with CTRCD using echocardiography. We assessed the ECG indices on 12-lead ECG recordings before and after treatment in 15 patients; eight patients were excluded due to conduction disturbances or atrial fibrillation. Results: CTRCD was detected at a median of 475 (interquartile range, IQR: 341–1333) days after initiating chemotherapy. The evaluation of ECG indices preceding CTRCD development was performed 93 (IQR: 52–232) days before the detection of CTRCD. In the stage of CTRCD, the most significant ECG change was T-wave flattening in leads V3–V6 (12 patients, 80%). Additionally, QTa prolongation was observed in leads I and aVL (n=10, 66%), leads II, III, and aVF (n=9, 60%), and leads V3–V6 (n=10, 73%). These ECG changes were not observed before the treatment but were detected mildly in the pre-CTRCD stage, which subsequently worsened in the CTRCD stage.Conclusions: This study indicated that T-wave changes and QTa prolongation may be useful as an early indicator before the onset of CTRCD in patients with DOX-induced cardiotoxicity.

Oculodermal Melanocytosis

Oculodermal melanocytosis (ODM), though rare, is associated with a number of sight-threatening complications including glaucoma. The purpose of this Case Series study was to determine the ophthalmic features in patients diagnosed with ODM. Here, we describe five patients presented with ODM, with the most common ocular features identified being hyperpigmentation of the conjunctiva, sclera and heterochromia iridis. Others included hyperpigmentation of trabecular meshwork, glaucoma, cataract, retinal detachment and ocular hypertension in one patient. As such, all patients with ODM should have a comprehensive ocular evaluation.

AbstractObjective:To determine whether the use of tissue spears to remove otorrhoea from Aboriginal children's ear canals improves hearing in the affected ear.Design:Case series study with controls.Methods:The study comprised 61 Aboriginal children from communities in the remote arid zone of South Australia who had otorrhoea obscuring the tympanic membrane in 1 or both ears. Eighty ears were treated with tissue spears, and hearing was assessed before and after treatment.Results:Forty-two children had unilateral and 19 had bilateral active disease. An additional 13 ears without otorrhoea served as controls. Improvement by 5 dB HL or greater in a four-frequency pure tone average occurred in 41.3 per cent of treated ears. Subsequently, blinded audiologists made qualitative judgements that a functional improvement in hearing had occurred after tissue spear use in 28.4 per cent of ears.Conclusion:Tissue spears can improve hearing thresholds in a significant proportion of children with otorrhoea. However, the duration of the effect is unknown.

Abstract Backgrounds: The COVID-19 pandemic has great impact on hospitals and patients. The fourteen-day quarantine caused surgery of RRD postponed. To explore the risk factors of rhegmatogenous retinal detachment (RRD) progression in a group of patients whose surgery was postponed during the top-level emergency response of COVID-19.Methods: Retrospective case series study. The information on RRD patients who received surgeries in Beijing Tongren Hospital's retina service from February 16, 2020, to April 30, 2020 has been collected retrospectively. The history, manifestation on presentation and admission, and progression of RRD were recorded. RRD progression was defined as the presence of either choroidal detachment (CD) or proliferative vitreoretinopathy (PVR) progression during the quarantine period. Risk factors were analyzed using the Cox proportional hazards model, survival analysis, and logistic regression.Results: There were 79 cases enrolled in this study. The median time from the patients' presentation at the clinic to admission for surgery was 14 days (3–61 days). There were 70 cases (88.6%) who did not present to the hospital within one week of the onset of visual symptoms. There were 69 (87.3%) macular-off cases at the presentation. There were 27 (34.2%) cases combined with choroidal detachment. There were 49 (62.0%) cases with PVR B, 22 (27.8%) cases with PVR C, 4 (5.1%) cases with PVR D, and 4 (5.1%) cases with PVR A. After the 14-day quarantine, 21 (26.6%) cases showed RRD progression, and 9 cases showed RD regression at the time of surgery. Neither the time of onset of the visual symptom (p=0.46) nor the time between presentation and admission (p=0.31) was significantly different between the patients with RRD progression and patients without RRD progression. The combination of CD (3.61, 1.86-6.99, p=0.001) and retinal breaks located posterior to the equator (3.78, 1.25-11.45, p=0.02) were factors related to the progression of RRD. Conclusions: In the cases enrolled in our study during the COVID-19 outbreak period, the RRD progression risk factors included a combination of CD and retinal breaks posterior to the equator. Ophthalmologists should schedule the surgeries for RRD patients with these signs as soon as possible.

Sensory disorder is a factor preventing recovery from motor paralysis after stroke. Although several robot-assisted exercises for the hemiplegic upper limb of stroke patients have been proposed, few studies have examined improvement in function in stroke patients with sensory disorder using robot-assisted training. In this study, the efficacies of robot training for the hemiplegic upper limb of three stroke patients with complete sensory loss were compared with those of 19 patients without complete sensory loss. Robot training to assist reach motion was performed in 10 sessions over a 2-week period for 5 days per week at 1 h per day. Before and after the training, the total Fugl–Meyer Assessment score excluding coordination and tendon reflex (FMA-total) and the FMA shoulder and elbow score excluding tendon reflex (FMA-S/E) were evaluated. Reach and path errors (RE and PE) during the reach motion were also evaluated by the arm-training robot. In most cases, both the FMA-total and the FMA-S/E scores improved. Cases with complete sensory loss showed worse RE and PE scores. Our results suggest that motor paralysis is improved by robot training. However, improvement may be varied according to the presence or absence of somatic sensory feedback.
