    PURPOSE: To identify the optical coherence tomography (OCT) findings in patients with age-related macular degeneration (ARMD) treated with photodynamic therapy (PDT). STUDY DESIGN: Open, non-randomized, interventional case series. METHODS: ARMD patients were submitted to a complete ophthalmological examination, fluorescein angiography, and OCT at baseline (V0), 3, 6, 9 and 12 months (V3, V6, V9 and V12, respectively). PDT was carried out according to the TAP study. Visual acuity (VA) was measured using the logMAR ETDRS chart. The following foveal measurements were performed: foveal intraretinal thickness (FIRT), foveal choriocapillaris - RPE complex thickness (FCC-RPET) and total foveal thickness (TFT). The extrafoveal thicknesses measured were: extrafoveal intraretinal thickness (EFIRT), extrafoveal choriocapillaris - RPE complex thickness (EFCC-RPET) and total extrafoveal thickness (TEFT). Statistical analysis was performed using the block variance analysis test. RESULTS: Twenty-three eyes of 23 patients were enrolled. This study identified nine OCT patterns: 1) thickening of the foveal intraretinal layers; 2) thickening of the extrafoveal intraretinal layers; 3) thickening of the foveal choriocapillaris - RPE complex; 4) thickening of the extrafoveal choriocapillaris - RPE complex; 5) intraretinal fluid; 6) subretinal fluid; 7) subretinal pigment epithelium (RPE) fluid; 8) vitreo-retinal adhesion; 9) foveal depression. At baseline, FIRT and TFT were 398.5 µ and 639.2 µ, respectively. At V12 they were 173.7 µ e 423.9 µ, respectively, and this change was statistical significant (p=0.008 e p=0.003, respectively). The variation of the other foveal and extrafoveal measurements were not statistically significant. Foveal depression was present at baseline in 36.4% of the eyes, whereas at V12 it was present in 78.3%. Subretinal fluid was present in 36.4% of eyes at V0 and in 8.7% at V12. VA at baseline was 0.93 and it V12 was 1.04 (p=0,127). CONCLUSIONS: Visual acuity was stable throughout the study. Foveal depression was reestablished in 78.3% at V12. FIRT and TFT decreased at a statistical significant level, from V0 to V12.

    Força axial de língua em diferentes faixas etárias
    (Sociedade Brasileira de Fonoaudiologia, 2011-09-01) Motta, Andréa Rodrigues [UNIFESP]; César, Cibele Comini; Bommarito, Silvana [UNIFESP]; Chiari, Brasilia Maria [UNIFESP]; Universidade Federal de Minas Gerais; Universidade Federal de São Paulo (UNIFESP)
    PURPOSE: To analyze the maximum axial force, the mean axial force, the amount of energy accumulated by the tongue, and the time taken to reach the maximum axial force, in different age ranges. METHODS: The records of 92 individuals - students, staff and visitors at an university -, 29 (32.6%) men and 63 (67.4%) women, with ages between 14 and 53 years old, were analyzed. Subjects were divided into four age groups: 14 to 18 years, 19 to 23 years, 24 to 28 years, and 29 to 53 years. Each subject underwent clinical and instrumental assessment of the tongue. Instrumental assessment used FORLING. Data were statistically analyzed. RESULTS: Regarding the maximum force, the mean force and the tongue's accumulated energy, no differences were observed between groups. Regarding the time taken to reach the maximum force, the greatest values were obtained at the age range from 14 to 18 years (4.5 s), and the shortest values, at the age range from 19 to 23 years (3.1 s), with significant difference between the groups (p=0.001). CONCLUSION: Only the time taken to reach the tongue's maximum force is influenced by age range, indicating that teenagers are not able to reach the maximum lingual force as fast as young adults.

    Técnica para injeção intravítrea de drogas no tratamento de doenças vítreorretinianas
    (Conselho Brasileiro de Oftalmologia, 2008-12-01) Rodrigues, Eduardo Buchele [UNIFESP]; Maia, Maurício [UNIFESP]; Penha, Fernando Marcondes [UNIFESP]; Dib, Eduardo [UNIFESP]; Bordon, Arnaldo Furman [UNIFESP]; Magalhães Júnior, Octaviano [UNIFESP]; Farah, Michel Eid [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Intravitreal injections are the standard technique applied in the treatment of some vitreoretinal diseases. In this paper the technique and complications of intravitreal injections are presented. In summary, the procedure involves various consecutive steps. Initially, days before the treatment topical antibiotics and acetazolamide may be prescribed for reduction of the ocular flora and intraocular pressure. Before the injection, the pupil should be dilated and topical anesthesia should be achieved. Injection shall be performed in the operating room under sterile conditions, the surgeon should wear surgical gloves and mask. The eye is then exposed with sterile blepharostat and sterile-drape thereby providing protection of the needle against the contact with contaminated lashes and lids. Injection is done 3.5 mm from the limbus through the pars plana. The needle should be inserted up to 6 mm into the vitreous cavity. Immediately after injection the patient must be examined by indirect ophthalmoscopy to verify central artery perfusion and complications as vitreous hemorrhage. Visual acuity better than light perception should be detected right after injection. If persistent central retinal artery occlusion is diagnosed, anterior chamber paracentesis should be performed. The patient may be discharged with an occlusive patch. Examination at the first postoperative day should exclude various complications such as endophthalmitis, and topical steroid and antibiotics should be prescribed for 7 days. Some complications encountered after intravitreal injections include retinal detachment, vitreous hemorrhage, cataract, uveitis, ocular hypertension, or endophthalmitis.
