Retina -> Aquired Macular Diseases
Patient: 71-year-old pseudophakic man. Ocular Medical History: retinal tears with 360° macula-off RRD in left eye, best corrected visual acuity (VA) hand motion, pars plana vitrectomy and laser photocoagulation followed by 14% C3F8 exchange; (1) one month after surgery VA 0.2; (2) two months after vitrectomy VA unchanged, cystoid macular edema (ME) with a foveal thickness of 471 μm; (3) two months and two weeks after vitectomy, the macular edema had increased to 634 μm, intravitreal injection of triamcinolone acetonide (TA); (4) one week after TA injection, VA 0.3 and foveal thickness decreased to 306 μm; (5) two months after TA injection, VA 0,4 and minimal intraretinal fluid was present on OCT; (6) three months after TA injection, foveal thickness again increased to 631 μm, Ozurdex® (Allergan Inc., Irvine, CA, USA); (7) two months after injection of Ozurdex, VA 0.4 and foveal thickness had decreased to 327 μm. Findings: 1. OCT: (a) two months after vitrectomy: cystoid macular edema (ME), foveal thickness of 471 μm; (b) two months and two weeks after vitectomy: macular edema increased to 634 μm; injection of triamcinolone acetonide (TA); (c) one week after TA injection, foveal thickness decreased to 306 μm; (5) two months after TA injection, minimal intraretinal fluid; (6) three months after TA injection, foveal thickness again increased to 631 μm, Ozurdex® (Allergan Inc., Irvine, CA, USA); (7) two months after injection of Ozurdex, foveal thickness had decreased to 327 μm. 2. Colour Photography: just after Ozurdex application, no retina visible. 3. Colour Photography: 2 months after Ozurdex application, retina visible.
