A catheter-assisted interlaminar Cervical Epidural Steroid Injection (CESI) was performed under fluoroscopic guidance, targeting the affected C2-C6 levels. Significant improvement was observed after this procedure, with decreased pain scores (visual analogue scale (VAS) 8 to 2) and improved mobility. This technique not only enhances the effectiveness of CESI but also reduces the likelihood of complications such as stroke or epidural hematoma and thus provides an alternative treatment option for patients with multiple stenotic levels who are unsuitable for surgery or are unresponsive to conservative therapy such as medication or physical therapy.展开更多

The outcome measures were vitreous seeds regression, need for other treatment modalities to achieve ocular salvage and treatment side effects. METHODS： A prospective interventional comparative nonrandomized study included RB eyes developed secondary vitreous seeds during the period of follow up. They subdivided into two groups： study group Ⅰ where posterior sub-Tenon＇s carboplatin （20 mg/2 mL） was injected and study group Ⅱ where intravitreal melphalan （20 μg/0.1 mL） was injected. The injections repeated every 2-4wk. RESULTS： Thirty-three eyes were included in the study. Seventeen eyes （16 patients） in study group Ⅰ and 16 eyes （16 patients） in study group Ⅱ. Ten eyes （30.3%） were completely salvaged following local chemotherapies, Ocular salvage was 23.5% following posterior sub-Tenon＇s carboplatin injection versus 37.5% following intravitreal melphalan raised to 47.1% and 75% with addition of external beam radiotherapy （EBR） with no statistically significant difference between the study groups （P=0.16）. A statistically significant correlation was found between ocular salvage rate and type of vitreous seeds either dust, spheres and clouds （r=0.42, P=-0.015） and eyes harbor new solid tumor growth （r=0.35, P=0.045）. The mean and median follow up periods following local chemotherapy injections were 2.0y in the study group Ⅰand 2.37y in the study group Ⅱ. Few complications were reported： periorbital edema in all eyes and ocular motility disturbances in 13 eyes （76.5%） following posterior sub-Tenon＇s carboplatin injection. Vitreous hemorrhage developed in 2 eyes （12.5%） and localized retinopathy in 5 eyes （31.25%） following intravitreal melphalan. ~ CONCLUSION： Local chemotherapy for treatment of RB with secondary vitreous seeds is safe and can salvage 30.3% of eyes without EBR. There is a superiority of intravitreal melphalan in ocular salvage however, no statistically significant difference between both groups.展开更多

METHODS: We retrospectively reviewed 810 eyes of 405 patients who underwent intravitreal DEX implantation due to macular edema caused by diabetic and retinal venous occlusion in our clinic. The eyes having no injection were determined as the control group. The examination findings of the patients before the injection and 3 mo after the injection and optical coherence tomography(OCT) images were scanned. The pre-injection OCT findings and OCT findings of the patients having no posterior vitreous detachment(PVD) and determined to have partial PVD were compared. RESULTS: The separation in vitreoretinal adhesion and total PVD development of DEX-injected 56/208(26.9%) eyes were statistically greater in comparison with the 12/129(9.3%) eyes that had not been injected(P=0.001). PVD development was observed more in the patients that were younger, had larger macula thickness and lower visual acuity. CONCLUSION: It can be stated that intravitreal DEX implant induces PVD development. Prospective, controlled studies are required in order to determine prognosis of vitreoretinal disease in PVD-developed patients and in non-PVD-developed patients.展开更多

We present a unique treatment method and magnetic resonance (MR) images of this condition. The patient was a 43-year-old male with a chief complaint of abnormal occlusion. Regarding the present status, there was no occlusion on the right side. No temporomandibular joint pain, myalgia, or clicking were observed while mouth opening. On MR images, the posterior disc displacement without reduction on the right was observed and it was assumed that occlusal abnormality was due to this condition. We treated him with the following methods. After injection into the superior articular cavity with 2% lidocaine, a sodium hyaluronate preparation was injected followed by intermaxillary traction applied using rubber. The recovery of occlusion was confirmed in follow-up at 5 days after treatment. In the 13th days, the intermaxillary traction was removed. On MR images, the right disc condition was changed to anterior disc displacement with reduction. We consider our treatment methods are effective for this clinical condition.展开更多
