RESUMO

ABSTRACT A 69-year-old female was referred with sudden unilateral painless decreased vision that began 2 days after uncomplicated cataract surgery in the left eye. Visual acuity was hand motion and biomicroscopy showed a mild anterior chamber reaction, no hypopyon, and an intraocular lens that had been placed within the capsular bag. A dilated fundus examination revealed optic disk edema, widespread deep and superficial intraretinal hemorrhages, retinal ischemia, and macular edema. A cardiological evaluation was normal and thrombophilia tests were negative. After surgery, prophylactic vancomycin (1mg/0.1ml) had been injected intracamerally. The patient was diagnosed with hemorrhagic occlusive retinal vasculitis likely secondary to vancomycin hypersensitivity. Recognition of this entity is important to ensure early treatment and the use of intracameral vancomycin in the fellow eye should be avoided after cataract surgery.


RESUMO Esse caso se refere a uma paciente de 69 anos, sexo feminino, com relato de baixa acuidade visual súbita e indolor no olho esquerdo, de início 2 dias após cirurgia de catarata sem complicações. A acuidade visual era de movimento de mãos e a biomicroscopia mostrou reação de câmara anterior moderada, sem hipópio, e lente intraocular posicionada dentro do saco capsular. A fundoscopia evidenciou edema de disco óptico, hemorragias difusas intrarretinianas superficiais e profundas, isquemia retiniana e edema macular. A avaliação cardiológica foi normal e os testes para trombofilia foram negativos. Ao final da cirurgia foi injetado antibioticoprofilaxia com vancomicina (1mg/0,1ml) na câmara anterior. A paciente foi diagnosticada com vasculite hemorrágica oclusiva da retina secundária à hipersensibilidade a vancomicina. O reconhecimento dessa entidade é importante para o tratamento precoce e para evitar o uso de vancomicina intracameral em caso de cirurgia de catarata no olho contralateral.

RESUMO

PURPOSE: This paper introduces a surgical technique for the sutureless management of zonular dialysis greater than 120° using a capsular tension segment (CTS) or a modified capsular tension ring (m-CTR; CTR with suturing eyelets) and a haptic removed from a 3-piece polypropylene IOL. METHODS: A CTR is used as normal. Cataract removal is followed by connection of the CTS or m-CTR to the single haptic and created using heat to make a flange in one haptic's extremity. The other extremity is placed in the CTS or m-CTR's central hole. The CTS or m-CTR/flanged-haptic complex is introduced into the capsular bag and aligned with the weakest zonular quadrant. A 30-gauge needle guides the externalization of the free haptic extremity through the adjacent pars plana and creates a flange on the second haptic tip permitting intrascleral fixation of the CTS or m-CTR. RESULTS: The result is a successful IOL implantation with a sutureless technique. CONCLUSIONS: This double-flanged m-CTR/CTS technique allows suture-free option for managing zonular weakness or dialysis while performing cataract surgery.
