Comparison of Color Fundus Photography, Infrared Fundus Photography, and Optical Coherence Tomography in Detecting Retinal Hamartoma in Patients with Tuberous Sclerosis Complex / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>A sensitive method is required to detect retinal hamartomas in patients with tuberous sclerosis complex (TSC). The aim of the present study was to compare the color fundus photography, infrared imaging (IFG), and optical coherence tomography (OCT) in the detection rate of retinal hamartoma in patients with TSC.</p><p><b>METHODS</b>This study included 11 patients (22 eyes) with TSC, who underwent color fundus photography, IFG, and spectral-domain OCT to detect retinal hamartomas. TSC1 and TSC2RESULTS: The mean age of the 11 patients was 8.0 ± 2.1 years. The mean spherical equivalent was -0.55 ± 1.42 D by autorefraction with cycloplegia. In 11 patients (22 eyes), OCT, infrared fundus photography, and color fundus photography revealed 26, 18, and 9 hamartomas, respectively. The predominant hamartoma was type I (55.6%). All the hamartomas that detected by color fundus photography or IFG can be detected by OCT.</p><p><b>CONCLUSION</b>Among the methods of color fundus photography, IFG, and OCT, the OCT has higher detection rate for retinal hamartoma in TSC patients; therefore, OCT might be promising for the clinical diagnosis of TSC.</p>

Value of Seeking Tumor Cells Through Cerebrospinal Fluid in Retinoblastoma / 实用儿科临床杂志

Objective To explore the value of seeking tumor cells through cerebrospinal fluid in the metastasis and prognosis of retinoblastoma.Methods Two hundred and fifty-six cases clinic diagnosed retinoblastoma were collected,154 cases were boys and 102 cases were girls.There were 85 children with bilateral disease and 171 children with unilateral disease.Lumbar puncture was examined before treatment,compare the result and prognosis.Children who were found tumor cells in their cerebrospinal fluid were treated with 6 to 9 cycles of systemic chemotherapy with CTV(carboplatin,teniposide and vincristine)protocol and 8 to 10 intrathecal injections with cytrarabine,methotrexate and dexametha-sone.Follow-up were between 8 to 23 months,the mean time was 14.6 months.Results There were 8 cases found tumor cells in their cerebrospinal fluid in all 256 children,one of them died of wide spread intracranial metastasis;the other patient was given high dose chemotherapy with autologous perip-heral stem cell transplantation(APBSCT) because of intracranial metastasis,follow-up to now the patient′s condition was stable.The rest 6 children were enucleated in follow-up period,there were 4 cases(67%) with the histopathology of the eye indicates spread of tumour cells beyond the lamina cribrosa,and 2 cases with invading the cut end of the optic nerve.Six children were no metabasis evidences at other tissues.Conclusions Intracranial metastasis is the common metastasis style in retinoblastoma,so lumbar puncture to seeking tumor cells was important to evaluate intracranial metastasis,early treatment and prognosis.
