Article: Midterm results of low-dose intravitreal triamcinolone as adjunctive treatment for proliferative vitreoretinopathy.
[show abstract] [hide abstract]
ABSTRACT: To evaluate the midterm anatomical and functional outcomes of intravitreal injection of low-dose triamcinolone acetonide in silicone oil-filled eyes as an adjunctive treatment for proliferative vitreoretinopathy. This is a retrospective interventional case series. Patients with proliferative vitreoretinopathy grade C or D received pars plana vitrectomy combined with silicone oil tamponade and intravitreal injection of 2 mg of triamcinolone acetonide in the first stage and silicone oil removal in the second stage. Primary outcome measures were retinal reattachment rate and best-corrected visual acuity. In all, 37 eyes from 37 patients were included in this study. The mean follow-up duration was 22.9 ± 9.6 months. Retina was reattached in 36 (97.3%) eyes at the last visit. The mean best-corrected visual acuity was 1.76 ± 0.56 logMAR at baseline, which improved to 0.87 ± 0.60 logMAR at the last visit (P < 0.001). Best-corrected visual acuity increased in 31 (83.8%) eyes, remained unchanged in 5 (13.5%) eyes, and decreased in 1 (2.7%) eye at last visit compared with baseline. Low-dose (2 mg) triamcinolone acetonide intravitreal injection as an adjunct to vitrectomy and silicone oil tamponade in treating proliferative vitreoretinopathy (grade C or D) appears to be effective and safe.Retina (Philadelphia, Pa.) 02/2011; 31(6):1137-42. · 2.93 Impact Factor -
Article: Changes in first- and second-order multifocal electroretinography in idiopathic macular hole and their correlations with macular hole diameter and visual acuity.

ABSTRACT: To evaluate the first- and second-order multifocal electroretinography (mfERG) responses in patients with idiopathic macular hole, and their correlations with macular hole diameter measured by optical coherence tomography (OCT) and visual acuity. Twenty-four eyes of 24 patients with idiopathic macular hole underwent mfERG and OCT examinations. The response amplitudes and implicit times of the first- and second-order mfERG were analyzed and compared with 20 age-similar normal control subjects. Correlation analyses between visual acuity, apical and basal diameters of the macular hole, and the first- and second-order mfERG amplitudes and implicit times were performed. The first-order mfERG N1 and P1 amplitudes in the central two concentric rings were reduced in macular hole eyes compared with controls (p < 0.006). For the second-order mfERG, only the N1 mfERG amplitude was significantly reduced at ring 6 in macular hole eyes compared with controls (p = 0.030). Correlation analysis showed that apical diameter of macular hole was significantly correlated with the first-order N1 amplitude of rings 2 to 5 (p < 0.024), the first-order P1 amplitude of rings 2 to 6 (p < 0.05), as well as the second-order P1 mfERG amplitudes of rings 3 to 6 and N1 amplitudes of rings 3 to 5 (p < 0.05). LogMAR visual acuity showed significant correlation with apical diameter of the macular hole (p = 0.002), and also with the first-order P1 amplitude of ring 2 (p = 0.024). In eyes with idiopathic macular hole, reductions in first-order mfERG responses are limited to the central macula, while the second-order mfERG response abnormalities involved more of the peripheral macular region. OCT measurement of apical and not the basal diameter of macular hole correlated with the severity of retinal dysfunction assessed by both mfERG and visual acuity.Albrecht von Graæes Archiv für Ophthalmologie 09/2009; 248(4):477-84. · 2.17 Impact Factor
