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.
