- Palpebral position interdependence in blepharoptosis: comparison of the effect of instillation of 10% phenylephrine drop and digital lifting(2014) PEREIRA, Ivana Cardoso; MATAYOSHI, SuzanaPurpose: To quantify and compare the effects of instillation with 10% phenylephrine and digital lifting on the contralateral upper eyelid of patients with involutional bilateral blepharoptosis. Methods: The present prospective clinical study involved patients with involutional bilateral blepharoptosis who underwent two tests: 1) digital lifting of the more ptotic eyelid and observation of the effect on the contralateral eyelid and 2) instillation of two drops of 10% phenylephrine in the more ptotic eye and observation of the effect on the contralateral eyelid. Patients were filmed before and 5, 10, and 15 min after instillation, and the resulting images were analyzed to obtain eyelid measurements. The results were tested using a linear mixed-effects model. Results: A total of 27 patients, ranging from 52 to 82 years of age (mean age 68.51 +/- 8.21 years), 24 (88.88%) of whom were women, were included in the present study. In eyes that received instillation, the marginal distance reflex-1 (MDR1) values increased from baseline (1.21 +/- 0.60 mm) until 10 min after instillation, then remained statistically unchanged until 15 min after instillation (2.42 +/- 0.90 mm). Significant differences were observed in the contralateral eye of the group that underwent digital lifting (1.51 +/- 0.53 mm - 1.63 +/- 0.56 mm) and in the contralateral eye of the group that underwent 10% phenylephrine instillation (1.38 +/- 0.54 mm - 1.63 +/- 0.56 mm); p=0.02 and p<0.01, respectively. Conclusions: In all eyes, 10% phenylephrine elevated the upper eyelid, with improved eyelid height at 10 min after instillation. Significant differences were observed in the height of the contralateral eyelid when compared before and after each intervention in each group; however, this difference was very small and nearly undetectable by conventional clinical evaluation in the digital lifting group. However, the 10% phenylephrine eye-drop test resulted in substantial changes in MDR1 values in the treated and contralateral eyes, indicating clinical and statistical efficiency.

Methods: Eighteen patients with hemifacial spasm were submitted to complete ophthalmologic exam, corneal topography and Orbscan previously botulinum toxin application and one month afterwards. They were evaluated for keratometry, BFS (anterior and posterior) and Roush value. Results: There were no statistical differences between eyes with hemi facial spasm and normal eyes related to keratometric values by topography and in the parameters evaluated by Orbscan as Roush and best fit sphere (anterior or posterior) prior to or after treatment with botulinum toxin. Conclusion: This study has not shown statistical difference between the corneal curvatures when compared eyes with hemi facial spasm with the opposite normal eyes.bookPart Ptose palpebral(2022) GINGUERRA, Maria Antonieta; MATAYOSHI, Suzana; PEREIRA, Ivana Cardoso- Tratamento cirúrgico da blefaroptose congênita(2014) MATAYOSHI, Suzana; PEREIRA, Ivana Cardoso; ROSSATO, Luiz AngeloA blefaroptose é o posicionamento inadequado da pálpebra superior, estando abaixo de sua posição normal na posição primária do olhar, a qual seria 0,5 – 2mm abaixo do limbo superior. Pode causar bloqueio parcial ou completo do campo visual superior, além do comprometimento estético. As causas são categorizadas em congênitas ou adquiridas. É considerada congênita se presente ao nascimento ou diagnosticada no primeiro ano de vida. As principais técnicas utilizadas para o tratamento da ptose congênita são a ressecção da aponeurose do músculo levantador da pálpebra superior (MLPS) e a suspensão frontal. A medida da função do MLPS é o parâmetro mais importante na escolha da técnica cirúrgica. Quando a função é fraca, a suspensão frontal é mais indicada; a ressecção supramáxima do MLPS também pode ser empregada. Acima de 4 ou 5mm de função do MLPS, prefere-se a ressecção da aponeurose. Para a cirurgia de suspensão frontal, vários são os materiais utilizados, portanto apresentamos uma comparação entre os estudos mais relevantes. Discutiremos também particularidades em casos mais complicados, como as Síndromes da Blefarofimose e de Marcus-Gunn, além de técnicas cirúrgicas menos utilizadas e as complicações relatadas.
- Quantitative Comparison of the Effect of 10% Phenylephrine Instillation and Manual Elevation in Patients with Involutional Blepharoptosis(2017) PEREIRA, Ivana Cardoso; MATAYOSHI, SuzanaObjective: To compare the effect of 10% phenylephrine (PE) instillation and manual elevation (ME) on the upper eyelid position of the tested eye and the contralateral eye in patients with involutional blepharoptosis (IB). Methods: IB patients were submitted to two tests followed by observation of the effect on the contralateral eyelid: (1) ME of the more ptotic eyelid; and (2) instillation of two drops of 10% PE (phenylephrine test) in the more ptotic eye. The patients were filmed before and 5, 10, and 15 minutes after instillation. The upper eyelid margin reflex distance (MRD1) was measured using the software Image J, and the results were analyzed with the linear mixed-effects model. Results: The study included 70 patients aged 44-86 years, 64 of whom were female (91.43%), divided into three groups: subjects with unilateral IB, subjects with bilateral IB, and controls. The eye submitted to instillation with 10% PE displayed significant elevation during the first 10 min: from 1.33 +/- 0.66 mm to 2.06 +/- 0.89 mm (unilateral group), from 1.26 +/- 0.63 mm to 2.29 +/- 0.86 mm (bilateral group), and from 3.12 +/- 0.68 mm to 4.06 +/- 0.92 mm (control group). MRD1 decreased in the contralateral eye in IB patients, significantly more so after the phenylephrine test: PE vs. ME =18.9% versus 17.2% reduction in the unilateral group, and 13.6% versus 10.7% reduction in the bilateral group. The outcome was not influenced by IB severity and the concurrence of IB and eye dominance. Conclusion: Both ME and 10% PE affected the contralateral upper eyelid, but the response was significantly better with the latter.
bookPart Pálpebras e Vias Lacrimais(2016) MATAYOSHI, Suzana; PEREIRA, Ivana Cardoso; AOKI, Lísia; LUNARDELLI, Patricia; TELES, Juliana Grilo- Estudo comparativo entre imagens de câmera fotográfica convencional e smartphone para o telediagnóstico de tumores palpebrais.(2019) AOKI, Lisia; PEREIRA, Ivana Cardoso; MATAYOSHI, SuzanaABSTRACT Objective: to compare the accuracy of eyelid tumor diagnosis obtained by evaluating conventional camera images with the ones obtained by evaluating smartphone images. Methods: from January 2016 to July 2017, 36 patients underwent face-to-face external assessments and biomicroscopic examinations to establish clinical diagnoses. The lesions were photographed using Canon PowerShot SX530 HS Digital Camera (16.8 Megapixels) and Samsung GALAXY S4 smartphone camera. All lesions were resected and submitted to anatomopathological examinations. Preoperative images were sent to two specialists in eyelid diseases and then remotely analyzed. Data from in-person diagnoses and telediagnoses were compared with the gold standard of histological diagnosis. Results: the most frequent lesions were basal cell carcinoma (33.3%), actinic keratosis (19.4%), and nevus (13.9%). Kappa coefficient for the diagnosis of malignant lesion showed agreement between the two tele-evaluators in the conventional digital camera images (0.68) and in the smartphone images (0.78). The face-to-face examiner’s accuracy was of 94.4%; the tele-evaluators’ accuracy in the conventional digital camera images was of 83.3% and in the smartphone images varied from 80.6% to 86.1%. Comparing the in-person diagnoses with the telediagnoses (obtained by evaluating conventional digital camera images or smartphone images), there was no significant difference in the hit rates. Conclusion: for eyelid tumor telediagnosis, images obtained using smartphone camera were equivalent to those obtained using conventional digital camera.
