| description | Katarzyna Michalska-Małecka,1,2 Aneta Gaborek,2 Mariusz Nowak,3 Tomasz Halat,4 Mariola Pawłowska,2 Dorota Śpiewak2 1Department of Ophthalmology, School of Medicine in Katowice, Medical University of Silesia, Katowice, 2University Center of Ophthalmology and Oncology, Independent Public Clinical Hospital, Medical University of Silesia, Katowice, 3Pathophysiology Division, Department of Pathophysiology and Endocrinology, Medical University of Silesia, School of Medicine with Division of Density, Zabrze, 4Education and Medical Simulation Center, Medical University of Silesia, Katowice, Poland Abstract: The purpose of this study was to evaluate the impact of intravitreal dexamethasone implant (Ozurdex) on macular morphology and functions in eyes with macular edema (ME) secondary to retinal vein occlusion. Efficacy outcomes of the treatment were best-corrected visual acuity (BCVA) and central retinal thickness (CRT). Safety outcomes were intraocular pressure and cornea endothelial cell density. The study was conducted by the prospective analysis on 36 patients (17 women and 19 men) aged 28–77 years (the average age was 58±15 years) treated with the injection of dexamethasone implant because of the persistent ME at the Department of Ophthalmology and Ophthalmology Outpatient Clinic of the University Centre of Ophthalmology and Oncology in Katowice. The studied group included 16 patients with central retinal vein occlusion (16 eyes), and 20 patients with branch retinal vein occlusion (20 eyes). We found a significant increase of BCVA after first, second, and third month of treatment. Six months after the treatment, BCVA decreased, although not significantly compared with the value obtained in the third month. Two months after the intravitreal implantation of dexamethasone delivery system, CRT was 338±163 µm and was significantly lower compared with pretreatment value. Between third and sixth month after the treatment, we found insignificant increase of CRT compared with thickness observed in second month. Two months after the treatment, we found an increase in intraocular pressure in 36% of cases and a further decrease during the final visit 6 months after the treatment. During the treatment, there were no significant differences in endothelial cell density in branch retinal vein occlusion and central retinal vein occlusion. We found the intravitreal dexamethasone implant to be safe, well tolerated, and likely to lead to fast morphological and functional improvement of the macula and visual rehabilitation in patients with ME due to retinal vein occlusion. Keywords: macular edema, retinal vein occlusion, intravitreal implant, dexamethasone, best-corrected visual acuity, intraocular pressure |
