  ABSTRACT: To evaluate corneal graft survival over a 5-year period and to investigate whether factors related to the donor, eye bank practices, the recipient, surgery, and postoperative course influenced the outcome. Nine hundred ninety-eight patients were randomly selected and monitored in the subsequent 3 years from a cohort of 4500 recipients who underwent penetrating keratoplasty between 2001 and 2004. Cox univariate regression analysis was used to select variables to be included in a multivariate Cox proportional hazards model with a backward selection procedure to identify potential risk factors for graft failure. Graft survival curves were obtained from Kaplan-Meier estimates. Ectasia/thinning was the most common indication (49.1%), followed by regraft (16.1%) and pseudophakic corneal edema (PCE) (9.4%). The overall rate of graft failure was 10.7% with 6 cases of primary graft failure. Adverse reactions and complications (other than graft failure) were reported in 2.7% of patients in the first postoperative week and in 22.8% during the full follow-up period. The probability of 5-year survival was 83.0%, best in eyes with ectasia/thinning (96.0%) and less favorable in PCE (67.0%) and regraft (64.0%). Multivariate analyses showed the following variables to be linked to an increased risk of graft failure: regraft for any reason, all clinical indication except PCE, history of ocular inflammation/infection, pseudophakic/aphakic eye, vitrectomy, graft Descemet folds, adverse reactions/complications, and surgeons' low caseload. Penetrating keratoplasty shows an overall positive prognosis in the long-term. However, the probability of graft survival is largely dependent on the preoperative clinical condition and the lack of complications during follow-up.

  ABSTRACT: A 67-year-old woman developed refractory pseudophakic cystoid macular edema (CME) after uneventful phacoemulsification. Three months after an intravitreal injection of bevacizumab (1.25 mg), the CME was completely resolved, with resultant improvement in visual acuity.

  ABSTRACT: Purpose: Oxane HD is a mixture of silicone oil and a mixed fluorinated and hydrocarbonated olefin. The authors report a complication of Oxane HD as internal tamponade after removal of all visible heavy silicone oil. Methods: A 71-year-old man who underwent vitrectomy with Oxane HD presented with adherence of a residual bubble of Oxane HD in the macula after removal of all visible heavy silicone oil. In this patient OCT displayed an optical artifact due to the residual bubble, and fundus-related perimetry revealed a predominantly eccentric and relatively unstable fixation and very low macular sensitivity. Results: After surgical removal of the residual bubble, metamorphopsia resolved, sensitivity improved as revealed by fundus-related perimetry, and fixation became predominantly central and more stable. Conclusion: The authors suggest a way to manage this rare complication of Oxane HD as internal tamponade after removal of all visible heavy silicone oil.

  ABSTRACT: To describe our experience treating diplopia after orbital decompression in patients with thyroid orbitopathy. From May 1997 to July 2001, we performed orbital decompression on 102 patients (34 men and 68 women) with severe proptosis. In 10 (9.8%) of these patients who had no diplopia preoperatively, diplopia in primary gaze occurred after decompression. In 19 (18.6%) of the patients with diplopia in primary gaze before surgery, there was no modification of diplopia after decompression. In 24 (23.5%) of the patients with diplopia in primary gaze before surgery, a more severe imbalance occurred after decompression. Forty-four (83%) of these 53 patients underwent adjustable extraocular muscle surgery with the use of viscoelastic substances to gain single vision in primary position. In 9 (17%) of the patients, diplopia was resolved with the use of prismatic lenses. In 31 (70.4%) of 44 patients, we obtained a stable resolution of diplopia in primary position (minimum follow-up, 6 months). In 10 (22.7%) of these patients, a second surgery on the oblique muscles was necessary 6 months after the first surgery to resolve torsional diplopia. In 3 (6.8%) of the patients, diplopia has been resolved with prismatic lenses. Orbital decompression reduces proptosis, but may cause diplopia or worsen it.
