    Detecção de maculopatia hipotônica subclínica pelo OCT III após cirurgia filtrante
    (Conselho Brasileiro de Oftalmologia, 2006-12-01) Weyll, Mônica; Gilio, Adriana; Barbosa, Aline [UNIFESP]; Nicoli, Aguida Aparecida; Silveira, Regina Cele [UNIFESP]; Complexo Hospitalar Padre Bento; CHPB; Universidade Federal de São Paulo (UNIFESP); CHPB Setor de Glaucoma
    PURPOSE: To detect nondiagnostic hypotony maculopathy by OCT III after filtration surgery. METHODS: After surgery, patients with intraocular pressure less than 9 mmHg were submitted to OCT III examination. RESULTS: Seven (87.50%) patients with previous diagnosis of open angle glaucoma and one (12.50%) of them with acute angle closure glaucoma. Two patients (25.00%) presented hypotony maculopathy on OCT III examination. CONCLUSION: OCT III examination seems to be a good diagnostic method to detect subclinical hypotony maculopathy after filtration surgery.

    Intraocular pressure, corneal thickness, and corneal hysteresis in Steinert's myotonic dystrophy
    (Conselho Brasileiro de Oftalmologia, 2011-06-01) Garcia Filho, Carlos Alexandre de Amorim [UNIFESP]; Prata, Tiago dos Santos [UNIFESP]; Sousa, Aline Katia Siqueira [UNIFESP]; Doi, Larissa Morimoto [UNIFESP]; Melo Jr., Luiz Alberto Soares [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    PURPOSE: Low intraocular pressure (IOP) measured by Goldmann applanation tonometry (GAT) is one of the ocular manifestations of Steinert's myotonic dystrophy. The goal of this study was to evaluate the corneal-compensated IOP as well as corneal properties (central corneal thickness and corneal hysteresis) in patients with myotonic dystrophy. METHODS: A total of 12 eyes of 6 patients with Steinert's myotonic dystrophy (dystrophy group) and 12 eyes of 6 age-, race-, and gender-matched healthy volunteers (control group) were included in the study. GAT, Dynamic Contour Tonometry (DCT-Pascal) and Ocular Response Analyzer (ORA) were used to assess the IOP. Central corneal thickness was obtained by ultrasound pachymetry, and corneal hysteresis was analyzed using the ORA device. In light of the multiplicity of tests performed, the significance level was set at 0.01 rather than 0.05. RESULTS: The mean (standard deviation [SD]) GAT, DCT, and corneal-compensated ORA IOP in the dystrophy group were 5.4 (1.4) mmHg, 9.7 (1.5) mmHg, and 10.1 (2.6) mmHg, respectively. The mean (SD) GAT, DCT, and corneal-compensated ORA IOP in the control group was 12.6 (2.9) mmHg, 15.5 (2.7) mmHg, and 15.8 (3.4) mmHg, respectively. There were significant differences in IOP values between dystrophy and control groups obtained by GAT (mean, -7.2 mmHg; 99% confidence interval [CI], -10.5 to -3.9 mmHg; P<0.001), DCT (mean, -5.9 mmHg; 99% CI, -8.9 to -2.8 mmHg; P<0.001), and corneal-compensated ORA measurements (mean, -5.7 mmHg; 99% CI, -10.4 to -1.0 mmHg; P=0.003). The mean (SD) central corneal thickness was similar in the dystrophy (542 [31] µm) and control (537 [11] µm) groups (P=0.65). The mean (SD) corneal hysteresis in the dystrophy and control groups were 11.2 (1.5) mmHg and 9.7 (1.2) mmHg, respectively (P=0.04). CONCLUSIONS: Patients with Steinert's myotonic dystrophy showed lower Goldmann and corneal-compensated IOP in comparison with healthy individuals. Since central corneal thickness and corneal hysteresis did not differ significantly between groups, the lower IOP readings documented in this dystrophy seem not to be related to changes in corneal properties.

    Variação da pressão intraocular após teste submáximo de força no treinamento resistido
    (Conselho Brasileiro de Oftalmologia, 2009-06-01) Conte, Marcelo [UNIFESP]; Scarpi, Marinho Jorge [UNIFESP]; Rossin, Reginaldo Alexandre; Beteli, Hélio Rubens; Lopes, Rodrigo Gustavo; Marcos, Haroldo Leão [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Escola Superior de Educação Física de Jundiaí; ESEFJ
    PURPOSE: To verify the intraocular pressure (IOP) after sub-maximal strength test. METHODS: 145 Physical Education freshmen (22.04 ± 4.17 years old; female and male) from Superior Physical Education School of Jundiaí (ESEFJ) were evaluated in an observacional study. The exclusion criteria were: media opacity and eyeball absence or changes. All subjects agreed to take part in this research and signed up the Informed Consent. IOP was measured by Perkins tonometer: i) pretest: just before the submaximal strength test performance and ii) post-test: immediately after the strength test. The strength test consisted in the one-repetition-maximum-assessment through repetition until fatigue. Resistance training exercises such as bench press, pulley dorsal high, shoulder press, arm curl and leg press 45º were performed. Statistical analyses were obtained through paired Student's t test. RESULTS: Decrease of IOP was observed after the strength test: 13.48 ± 3.32 vs.10.20 ± 3.72 (p<0.001) in the right eye and 13.13 ± 3.96 vs.9.74 ± 3.33 (p<0.001) in the left eye. CONCLUSION: IOP showed relevant decrease after submaximal strength test performance in college students.
