Case summary: An 85-year-old male with a history of stroke who had undergone cataract surgery 10 years ago at another hospital presented with repeated intraocular lens (IOL) dislocations of both eyes into the anterior chamber. He had previously undergone IOL scleral fixation once in his left eye and twice in his right eye, but IOL dislocation was still repeatedly occurring. The best-corrected visual acuity was 0.4 in both eyes. Hertel exophthalmetry was 20 mm in his right eye and 18 mm in his left eye. Painless limitation of motion at supraduction was observed in the right eye. Funduscopy showed newly appeared choroidal folding in the right eye, so orbital computed tomography (CT) with contrast was performed. The CT scans showed bilateral homogenously enhancing retrobulbar masses. Biopsy of the masses showed a MALToma. After radiation therapy, the choroidal folds resolved and exophthalmetry improved to 10 mm in both eyes. No additional IOL dislocation occurred. During 2.5 years of follow-up, there was no evidence of recurrence or distant metastasis of the MALToma. Conclusions: Orbital lymphomas can cause lid edema, exophthalmos, strabismus, and diplopia, and can be diagnosed with imaging modalities such as CT. Final diagnosis involves biopsy and radiation therapy or chemotherapy. If IOL dislocation occurs repeatedly, it may result from an increase in retrobulbar pressure, and concurrent choroidal folding using funduscopy is strongly recommended for imaging to check for the presence of retrobulbar masses.

Another 2.5 cm sized enhancing mass is shown in the left extraconal space with superior rectus muscle involvement. It suggests orbital lymphoma, bilateral.

(A) Tumor cells are negative for CD3 ( 200), (B) positive for CD20 antigen ( 200) and (C) negative for Cyclin D1 ( 200). (D) Small lymphoid cell proliferation was easy to be observed (Hematoxylin and eosin stain, 200). munoglobulin heavy chain (IgH) 유전자의중합효소연쇄반응을통한분자생물학적인분석을통해증식성결절 (lymphoid hyperplasia) 과더정확히감별진단을할수있게되었다. 10-12 본증례에서는 B 세포표지자인 CD20 양성이고, T 세포표지자인 CD3 음성으로 B 세포기원의림프종임을알수있었으며, 또한 Cyclin D1 음성으로외투세포림프종과감별을할수있었다. 병리학적으로는점막연관림프조직림프종에합당한소견을보였다. 인공수정체이탈은백내장수술합병증중의하나로약 0.2-2.0% 에서발생한다. 인공수정체이탈의선행요인에대해서는그동안여러연구들에서다루어져왔다. 수정체낭내이탈의경우거짓비늘증후군, 포도막염, 외상, 유리체절제술후상태, 긴장축등이원인으로알려져있고, 점진적인섬모체소대의약화로인해발생하기때문에진행이느리다. 한편, 수정체낭외이탈의경우인공수정체이차삽입술, 백내장수술시발생한후낭파열, 성숙백내장, neodymium-doped yttrium aluminium garnet; Nd:Y 3Al 5O 12 (Nd:YAG) 후낭절개술, 유리체절제술후상태등이원인으로알려져있고발생시기는다양하다. 13,14 이에본증례에서인공수정체이탈의원인은종괴에의해구후부압력이높아지면서안압이상승되고, 그에따른섬모체소대의약화에기인한인공수정체의불안정성이원인으로생각된다. 안와방사선치료이후뚜렷한구후부종괴크기가줄어들고안압이안정화되었으며, 이후로인공수정체이탈은더이상발생하지않았다. 현재까지국내에구후부의악성림프종으로인한인공수정체이탈에대해보고된바는없다. 또한, 맥락막주름의경우다양한질환과연관되어나타날수있는소견으로구조적으로맥락막내층, 브루크막, 망막색소상피층과감각신경망막까지구불거리는형상으로나타나게된다. 15 다양한원인이이를유발할수있는것으로알려져있는데, 갑상선안병증 16, 후부공막염 17,18, 종양 19,20, 저안압증 21, 공막돌륭술 22, 연령관련황반변성 15,18 등이그원 1413
