- Effect of a Single Intravitreal Bevacizumab Injection on Contrast Sensitivity and Macular Thickness in Eyes with Macular Edema from Central Retinal Vein Occlusion: A Prospective, Nonrandomized, Three-Month Follow-Up Study(2014) PRETI, Rony C.; RAMIREZ, Lisa M. V.; PIMENTEL, Sergio L. G.; NAKASHIMA, Yoshitaka; MACHADO, Cleide G.; PELAYES, David E.; MONTEIRO, Mario L. R.; TAKAHASHI, Walter Y.Purpose: To evaluate the results of intravitreal bevacizumab (IVB) injection on contrast sensitivity (CS), best-corrected visual acuity (BCVA), foveal thickness (FT) and macular volume (MV) as measured by optical coherence tomography in patients with macular edema (ME) from central retinal vein occlusion (CRVO). Methods: Sixteen consecutive eyes from 16 patients with ME from unilateral CRVO were treated with a single IVB injection. The CS, BCVA, FT and MV measurements were obtained before the treatment and 1 and 3 months after the injection. Results: CS demonstrated significant improvement at all spatial frequencies - 1.5, 3, 6, 12 and 18 cycles per degree (cpd) - 1 month after the injection and at 6 cpd at the 3-month follow-up. The mean BCVA measurements in log of the minimum angle of resolution (logMAR) units improved from 1.03 at baseline to 0.83 logMAR 1 month after the injection, but worsened to 0.97 logMAR at 3 months. The mean baseline FT +/- standard deviation (SD; 620.06 +/- 177.60 mu m) was reduced significantly 1 month (270.93 +/- 74.17 mu m) and 3 months (535.56 +/- 222.33 mu m) after the treatment. The mean baseline MV +/- SD (12,765.56 +/- 3,769.70 mm 3) was reduced significantly at the 1-month (8,324.93 +/- 932.04 mm(3)) and 3-month (11,319.44 +/- 3,044.74 mm(3)) follow-up visits. Conclusions: IVB improved CS, BCVA, FT and MV within a short time period (1 month). Although VA was not improved at 3 months, improvements were observed for CS, FT and MV, which indicates that, despite ME recurrence, there still was some benefit to visual function. (C) 2014 S.

- Fechamento espontâneo de buraco de mácula em olhos previamente vitrectomizados: relato de dois casos(2014) SUZUKI, Ana Claudia de Franco; ZACHARIAS, Leandro Cabral; NÓBREGA, Mário Junqueira; PRETTI, Rony Carlos; TAKAHASHI, Walter YukihikoThe spontaneous closure of a full-thickness macular hole (MH) developed after vitrectomy is very uncommon. We report a small series of cases (two patients) with this presentation. The first patient developed a MH 1 month after vitrectomy for an epirrretinal membrane and, the second one, 3 weeks after vitrectomy for rhegmatogenous retinal detachment. The MHs resolved spontaneously 2 months and 1 month after their documentation by optical coherence tomography(OCT), respectively. In this case report, we review the literature on spontaneous closure of MHs and discuss possible mechanisms for this rare event.
