RESUMO
PURPOSE@#We determined the effects of silicone tube tip fixation on the nasal wall using an absorbable suture during silicone tube intubation in patients with congenital nasolacrimal duct obstruction.@*METHODS@#Patients (55:71 eyes) diagnosed with congenital nasolacrimal duct obstruction and who underwent silicone tube intubation were divided into two groups: those in which the silicone tube was fixed to the nasal wall using an absorbable suture (fixed group) or not (non-fixed group). We investigated the percentage of silicone tube displacement, the time for displacement, the success of surgery, and the method of removing the silicone tube after surgery.@*RESULTS@#The mean age, percentage of early displacement within 1 month, time to displacement, and success rate of surgery were 2.4 years, 0% (0/35), 1.4 months, and 100% (35/35) in the fixed group (35 patients) and 1.8 years, 44% (16/36), 0.8 months, and 97% (35/36) in the non-fixed group (36 patients), respectively. Both groups were able to remove the silicone tube simply through lacrimal punctum at the outpatient clinic.@*CONCLUSIONS@#In patients with congenital nasolacrimal duct obstruction, silicone tube fixation at the nasal wall after silicone tube intubation can prevent early displacement of silicone tubes within 1 month. This is a simple and effective technique because it removes the silicone tube through the lacrimal punctum without general anesthesia or intravenous anesthesia.
RESUMO
PURPOSE: To report a case of choroidal metastasis caused by lung cancer in a young female who had no history. CASE SUMMARY: A 31-year-old female presented with decreased vision for 1 week. Fundus examination revealed an orange colored choroidal tumor and serous retinal detachment at superotemporal area of the optic disc on the left eye. On chest X-ray, atypical pneumonia or hematogenous metastasis was shown. Additionally, mammography, chest-abdomen computed tomography, lumbar magnetic resonance imaging, and transbronchial lung biopsy were performed and the patient was finally diagnosed with adenocarcinoma. The patient started systemic chemotherapy and visual acuity improved after 1 month. Tumor size and subretinal fluid also decreased. The tumor disappeared 2 months later and there was no recurrence. CONCLUSIONS: There are only few cases in which choroidal metastasis was observed in a young female patient with no history who had decreased visual acuity and was later diagnosed with lung cancer. Authors report this case because a satisfactory result was obtained from chemotherapy alone.
