Dear Editor,Iam Di: Jinho Lee from the Department of Ophthalmology, Seoul National University Hospital, Seoul, Korea. I am writing to present five case series of intraocular medulloepithelioma. Medulloepitheliomas are the second most common type of pediatric intraocular tumors. They display clinical characteristics similar to retinoblastomas, such as leukocorias and intraocular endophytic masses, and are extremely difficult to clinically differentiate from retinoblastomas.

AIM:To report CT and MR imaging findings of ocular adnexal mucosa-associated lymphoid tissue lymphoma associated with IgG4-related disease(IgG4-MALT lymphoma),a rare but clinically important complication of ocular adnexal IgG4-related ***:We retrospectively reviewed all cases of histologically confirmed ocular adnexal IgG4-related disease at three ter tiary and one secondary referral centers,between February 2003 and December *** cases of histopathologically diagnosed IgG4-MALT lymphoma were *** and MR images were analyzed by consensus of two experienced head and neck ***:Lacrimal glands were the main site of involvement in all seven *** lesions typically showed well-demarcated margins,iso-to hyperattenuation on precontrast CT,T2 hypo-to isointensity,T1 isointensity,and homogenous internal architecture with homogenous enhancement *** were mostly hyperdense and isointense to normal extraocular muscles on postcontrast CT and MR images,***:Unlike in typical ocular adnexal IgG4-related disease,T2 isointensity and hyperattenuation on precontrast CT images were noted in some IgG4-MALT lymphoma *** the findings may be nonspecific,the possibility of accompanying MALT lymphoma may need to be considered,when ocular adnexal lesions in patients clinically suspected of having IgG4-related disease are refractory to glucocorticoids and show T2 isointensity and hyperattenuation on precontrast CT for the optimal management of the ***,this is a case series of a very rare complication of ocular adnexal IgG4-related disease,and thus caution is warranted to generalize the conclusion.

眼内容物剜除术后眼内植入多孔聚乙烯巩膜后植入物的技术研究

引用

世界核心医学期刊文摘(眼科学分册) 2006年第3期 42-43页

作者： Choung H.-K khwarg S.I. 邢咏新 Department of Ophthalmology Seoul National University College of Medicine 28 Yongon-dong Chongno-gu Seoul 110-744 South KoreaDr.

The authors developed a technique for the retroscleral implantation of a porous polyethylene orbital implant after evisceration for the placement of an adequately large orbital implant without wound tension. The surgical results of the technique in 27 patients are reported. The technique involves the severance of the optic nerve after standard evisceration and the insertion of the orbital implant into the retroscleral and intraconal space through the side of the scleral shell. All patients received a 20-mm orbital implant. No complications such as infection, implant exposure, or worsened implant motility were observed during the average follow-up period of 22.4 months. Retroscleral implantation of the orbital implant after evisceration may be an appropriate procedure that allows placement of a large orbital implant without exposure or decreased implant motility.

视网膜母细胞瘤眼球摘除术后多孔性聚乙烯移植物暴露的处理

世界核心医学期刊文摘（眼科学分册） 2005年第4期1卷 54-54页

作者： Kim J.- H. khwarg S.- I. Choung H.K. 肖颖 Department of Ophthalmology Seoul Natl. Univ. Coll. of Medicine 28 Yongon- dong Chongno- gu Seoul 110- 744 South Korea Dr

BACKGROUND AND OBJECTIVE: To report the features and the management of porous polyethylene implant exposure in patients with retinoblastoma following enucleation. PA- TIENTS AND METHODS: The medical records of 33 patients (33 sockets) following enucleation and porous polyethylene implantation for retinoblastoma were reviewed. RESULTS: The mean age at enucleation was 24 months (range, 2 to 85 months). The exposure rate was 33% (11 cases), and the mean time from enucleation to exposure was 15 months (range, 7 to 29 months). One case was resolved only by supportive management, and the remaining 10 were successfully treated with a scleral patch graft and maintained well during a mean follow- up of 15 months after surgical repair. There was no statistical evidence that age, gender, implant size, or chemotherapy had an effect on implant exposure. CONCLUSIONS: Porous polyethylene implant exposure does not seem to be resolved by conservative management. We recommend early surgical management, such as scleral patch graft, as opposed to supportive management.
