bookPart Doenças do Nervo Óptico(2016) MONTEIRO, Mário Luiz Ribeiro; CUNHA, Leonardo Provetti; KREUZ, André Carvalho; OYAMADA, Maria Kiyoko- Phacoemulsification and 1% atropine eye drops for treatment of antimetropic congenital microcoria associated with cataracts(2019) FERREIRA, Bruno Fortaleza de Aquino; SCHMIDT, Marina Brandao; BARBOSA, Leonardo Jose; OYAMADA, Maria Kiyoko; CARRICONDO, Pedro CarlosA rare case of bilateral congenital microcoria associated with antimetropia in a 47-year-old man is here described. The patient presented with a chief complaint of progressive vision loss in his right eye over the past five years. A slit-lamp examination and ultrasound biomicroscopy confirmed congenital microcoria and cataracts. Phacoemulsification was performed using an iris expansion device and the anterior capsule was stained using the ""trypan down under"" technique. Preoperative considerations, the surgical approach, and postoperative management are discussed.
conferenceObject Comparative analysis of different treatment schedules in the course of Vogt-Koyanagi-Harada disease (VKHD)(2019) YAMAMOTO, Joyce H.; LAVEZZO, Marcelo Mendes; SAKATA, Viviane Mayumi; RODRIGUEZ, Ever Ernesto Caso; KANENOBU, Cintia; ABDALLAH, Smairah Frutuoso; MORITA, Celso; OYAMADA, Maria Kiyoko; HIRATA, Carlos Eduardoarticle 9 Citação(ões) na Scopus Pattern-reversal electroretinograms for the diagnosis and management of disorders of the anterior visual pathway(2011) HOKAZONO, Kenzo; OYAMADA, Maria Kiyoko; MONTEIRO, Mario Luiz RibeiroThe pattern electroretinogram is an electrophysiological test that assesses the function of inner retinal layers, particularly the ganglion cells layer of retina, using a reversing checkerboard or grating pattern that produces no change in average luminance over time. The normal pattern electroretinogram is composed of a proeminent positive component (P50) and a large later negative component (N95). Since structural damage that compromises the retinal ganglion cell layer can lead to pattern electroretinogram changes, particularly in the N95 amplitude, the test can be useful in the treatment of a number of anterior visual pathway diseases. In this article, we review the methods for recording pattern electroretinogram and its usefulness in the diagnosis and management of diseases including inflammatory, hereditary, ischemic and compressive lesions of the anterior visual pathway.conferenceObject New insights into structural and functional evaluation of the retina and optic nerve in Parkinson's disease(2023) MELLO, Luiz Marchesi; PARAGUAY, Isabela Bezerra; ANDRADE, Thais; ROCHA, Arthur do Nascimento; BARBOSA, Egberto; OYAMADA, Maria; MONTEIRO, Mario- Vogt-Koyanagi-Harada disease after discontinuation of systemic treatment(2022) SOUTO, Fernanda M.

- Pattern electroretinogram in neuromyelitis optica and multiple sclerosis with or without optic neuritis and its correlation with FD-OCT and perimetry(2013) HOKAZONO, Kenzo; RAZA, Ali S.; OYAMADA, Maria K.; HOOD, Donald C.; MONTEIRO, Mario L. R.To evaluate the ability of transient pattern electroretinogram (PERG) parameters to differentiate between eyes of patients with neuromyelitis optica (NMO), longitudinally extensive transverse myelitis (LETM), multiple sclerosis with optic neuritis (MS + ON), multiple sclerosis without optic neuritis (MS - ON), and controls, to compare PERG and OCT with regard to discrimination ability, and to assess the correlation between PERG, FD-OCT, and visual field measurements (VFs). Visual field measurements and full-field stimulation PERGs based on both 48- and 14-min checks were obtained from patients with MS (n = 28), NMO (n = 20), LETM (n = 18), and controls (n = 26). In addition, FD-OCT peripapillary retinal nerve fiber layer (RNFL) and segmented macular layer measurements were obtained and their correlation coefficients were determined. Compared to controls, PERG amplitude measurements were significantly reduced in eyes with NMO and MS + ON, but not in eyes with LETM and MS - ON. PERG amplitudes were significantly smaller in NMO and MS + ON eyes than in MS - ON eyes. PERG and OCT performance was similar except in NMO eyes where macular thickness parameters were more efficient at detecting abnormalities. A significant correlation was found between N95 amplitude values and OCT-measured macular ganglion cell layer thickness, total retinal thickness, and temporal peripapillary RNFL thickness. PERG amplitude was also significantly associated with VF sensitivity loss. No statistically significant difference was observed with regard to the best-performing parameters of the two methods. Pattern electroretinogram measurements were able to detect RNFL loss in MS + ON and NMO eyes, with a performance comparable to OCT. PERG amplitude measurements were reasonably well correlated with OCT-measured parameters.

E.article 16 Citação(ões) na Scopus Ophthalmologic manifestations of celiac disease(2016) MARTINS, Thiago Goncalves dos Santos; COSTA, Ana Luiza Fontes de Azevedo; OYAMADA, Maria Kiyoko; SCHOR, Paulo; SIPAHI, Aytan MirandaCeliac disease is an autoimmune disorder that affects the small intestine of genetically predisposed individuals. Ophthalmic manifestations are within the extra-intestinal manifestations, and can be divided into those of autoimmune disorders or those due to absorptive disabilities. This article reviewed the ophthalmologic manifestation of celiac disease. Ophthalmic symptoms are rare, but should be investigated in patients with celiac disease and taken into consideration as the first systemic manifestation.
