    A RANDOMIZED CONTROLLED TRIAL OF PANRETINAL PHOTOCOAGULATION WITH AND WITHOUT INTRAVITREAL RANIBIZUMAB IN TREATMENT-NAIVE EYES WITH NON-HIGH-RISK PROLIFERATIVE DIABETIC RETINOPATHY
    (2015) FERRAZ, Daniel A.; VASQUEZ, Lisa M.; PRETI, Rony C.; MOTTA, Augusto; SOPHIE, Raafay; BITTENCOURT, Millena G.; SEPAH, Yasir J.; MONTEIRO, Mario L. R.; Quan Dong Nguyen; TAKAHASHI, Walter Yukihiko
    Purpose: To compare the efficacy of panretinal photocoagulation (PRP) and intravitreal ranibizumab injection with PRP alone in patients with treatment-naive bilateral non-high-risk proliferative diabetic retinopathy. Methods: Sixty eyes of 30 patients were randomized either to the study group (SG) receiving PRP plus 2 ranibizumab injections or to the control group (CG) receiving PRP alone. Mean change in best-corrected visual acuity and in optical coherence tomography were compared at baseline and 1, 3, and 6 months. Results: Best-corrected visual acuity was significantly better at 6 months in the SG; however, there was decrease in best-corrected visual acuity in the CG. Central macula thickness decreased significantly at 6 months in SG when compared with baseline (-47.6 mm, P < 0.001) and did not reveal significant difference in the CG. In eyes with diabetic macular edema, best-corrected visual acuity increased by 3.6 letters (P = 0.06) in the SG and decreased by 4.4 letters in the CG (P = 0.003). Central macula thickness decreased by 69.3 mm (P = 0.001) in the SG and decreased by 45.5 mm (P = 0.11) in the CG. Conclusion: Intravitreal ranibizumab in combination with PRP can be an effective treatment in eyes with non-high-risk proliferative diabetic retinopathy and diabetic macular edema.

    Idiopathic polypoidal choroidal vasculopathy masquerading as choroidal tumors: one year follow-up of a peripheral lesion
    (2015) PRETI, Rony Carlos; MONTEIRO, Mario Luiz Ribeiro; MORITA, Celso; HELAL JUNIOR, John; ZACHARIAS, Leandro Cabral; FERRAZ, Daniel Araujo; PELAYES, David E.; TAKAHASHI, Walter Yukihiko
    This case report describes peripheral idiopathic polypoidal choroidal vasculopathy (IPCV) with a collection of small aneurysmal dilations that masqueraded as choroidal tumors in an elderly patient. A 68-year-old African American woman was referred to us with a suspected diagnosis of asymptomatic vascular choroidal tumor and choroidal capillary hemangioma, affecting the temporal peripheral fundus. Upon examination, optical coherence tomography (OCT) revealed two large hemorrhagic pigment epithelium detachments (PED), and indocyanine green angiography (ICG) confirmed the diagnosis of IPCV. One year later, there was reduction in the hemorrhagic pigment epithelium detachments and the lesion took on a different appearance, resembling a choroidal osteoma. No treatment was necessary despite the presence of multiple polyps. IPCV is a rare condition that can resemble other choroidal diseases depending on the stage of presentation. OCT is the best tool to determine the characteristics of the lesions, and indocyanine green angiography should be used to confirm the diagnosis. Not all cases require treatment.
