Intraocular pressure in silicon-oil tamponated eyes using a non-contact pulse synchronous tonometer: IOP measurement in vitrectomized and silicon-oil tamponated eyes by NT-4000

Objective To assess the reliability of intraocular pressure (IOP)measurement by means of NidekNT - 4000 tonometer in vitrectomized and siliconoil tamponaded (VSOT)eyes. Methods IOP was measured by means of NidekNT - 4000 and compared with standard Goldmann applanation tonometer (GAT)in 36 consecutive VSOT eyes and 36 normal eyes. Results In VSOT and nor mal eyes NidekNT - 4000 showed agreement with GAT (VSOT eyes mean difference:1. 83 ± 2. 64,P = 0 55;correlation:P < 0 0001,r = 0 95;Normal eyes mean difference:1 ± 2 8,P = 0 42;correlation:P = 0 0045,r = 0 69 ). Differences were similar be tween groups (P = 0 81). Conclusions NidekNT - 4000 tonometer offers a new affordable method to measure IOP in vitrectomized and siliconoil tamponaded eyes

Hepatocellular Carcinoma Metastasis to the Orbit in a Coinfected HIV+ HBV+ Patient Previously Treated with Orthotopic Liver Transplantation: A Case Report

Hepatocellular carcinoma rarely metastasizes to the orbit. We report a 45-year-old male, HBV+, HIV+, with a past history of a liver transplant for ELSD (end-stage liver disease) with hepatocellular carcinoma and recurrent HCC, who presented with proptosis and diplopia of the left eye. CT scans of the head revealed a large, irregular mass in the left orbit causing superior and lateral destruction of the orbital bone. Biopsy specimens of the orbital tumor showed features of metastatic foci of hepatocellular carcinoma. Only 16 other cases of HCC metastasis to the orbit have been described in literature, and this is the first case in a previously transplanted HIV+, HBV+ patient

Surgical reposition of a dislocated Ex-PRESS miniature device

PURPOSE: To present a technique of surgical reposition of the Ex-PRESS miniature glaucoma device when dislocated in corneal limbus. METHODS: A 54-year-old woman diagnosed with glaucoma, with a 3-month history of Ex-PRESS miniature implant, was referred to our department because of progressive intraocular pressure (IOP) rise. Slit-lamp biomicroscopy showed the posterior flange of the implant located in the corneal limbus; IOP was 34 mmHg. Surgical technique consisted of reopening of the conjunctiva and the scleral flap, excision of the corneal tissue covering the flange, and stitching the implant to the sclera with polyprolene suture. RESULTS: Postoperatively, IOP rapidly reduced to 5 mmHg and was balanced to 10 mmHg in the follow-up. CONCLUSIONS: Corneal dislocation of the Ex-PRESS implant, when associated with ocular hypertension, needs surgical treatment. Before considering a trabeculectomy, it could be valuable to attempt an implant reposition
