- Primary bilateral and symmetric MALT lymphoma of the lacrimal sac mimicking chronic dacryocystitis(2018) FEIJÓ, Eduardo Damous; ALMEIDA, Adriana Ribeiro de; MATAYOSHI, SuzanaAbstract We report a case of primary bilateral mucosa associated lymphoid tissue (MALT) lymphoma of the lacrimal sac. MALT lymphoma is a subtype of Non-Hodgkin's Lymphoma of the ocular adnexa. When the primary site of the lymphoma is the lacrimal sac, it mimics chronic dacryocystitis. This may delay diagnosis, with potentially lethal results.
- Fluorescein transit test time as a tool to assess lacrimal pump function after diode laser transcanalicular dacryocystorhinostomy and external dacryocysto-rhinostomy(2018) FEIJO, Eduardo Damous; LIMONGI, Roberto Murillo; MATAYOSHI, SuzanaBackground: Dacryocystorhinostomy (DCR) is the gold standard surgical treatment for nasolacrimal duct obstruction. External DCR is the traditional approach (EXT-DCR); however, the advent of minimally invasive surgeries and the development of optic fiber and laser technologies have made it possible to perform laser transcanalicular DCR (T-DCR), a minimally invasive procedure. This study measured the fluorescein transit time (FTT) after EXT-DCR or T-DCR to evaluate the lacrimal drainage and lacrimal pump function after these two types of DCR. Subjects and methods: A cross-sectional study of 50 patients who underwent EXT-DCR (EXT-DCR Group) or T-DCR (T-DCR Group), who were anatomically patent upon irrigation, with a minimum 6 months of follow up.The patients' FTT was measured; it was defined as the time from the instillation of the dye into conjunctival sac to its free flow from the rhinostomy site. This evaluation was performed through nasal endoscopy performed intranasally with a blue filter that enabled the faster detection of fluorescein from the ostium site.The mean FTTs of the two groups were compared using the two-sided Student's unpaired t-test. Other variables such as sex, age, previous lacrimal sac size, and the site and shape of the rhinostomy were evaluated to determine their possible relationships with FTT. Results:The EXT-DCR group had 80% female patients at a mean age of 58 years.TheT-DCR group had the same percentage of female patients (80%) and a mean age of 56 years.The mean FTT group was 47.48 sec in the EXT-DCR and 33.04 sec in the T-DCR group. Functional success was 88%in both groups. Conclusion: FTT in the DCR-T Group was significantly lower than in the EXT-DCR Group. No other variables exhibited a statistically significant correlation with FTT. Lacrimal drainage was found to be better after T-DCR than after EXT-DCR, results which show that this procedure could prevent lacrimal pump damage.
- A Comparative Study of Full-Thickness Blepharotomy Versus Transconjunctival Eyelid Lengthening in the Correction of Upper Eyelid Retraction in Graves' Orbitopathy(2018) GONCALVES, Allan C. Pieroni; NOGUEIRA, Thiago; GONCALVES, Ana Carolina Arato; SILVA, Luzia Diegues; MATAYOSHI, Suzana; MONTEIRO, Mario L. R.The study was designed to compare the outcome of full-thickness blepharotomy and transconjunctival eyelid lengthening in the correction of upper eyelid retraction (UER) in patients with Graves' orbitopathy (GO). This is a prospective randomized interventional study. Following ophthalmic examination, determination of the ocular surface disease index (OSDI) and photography, 27 patients with UER were randomly assigned to either graded full-thickness blepharotomy (G1) or transconjunctival Muller muscle recession and graded disinsertion of the levator palpebrae superioris muscle (G2). Six months later, patients were reevaluated. Digital images were analyzed with the assistance of customized software. A standardized ""normal range"" of upper eyelid height and contour was calculated based on healthy controls. The outcome of the two groups was compared. Forty-seven eyelids of 27 patients (19 female) with UER were included. Twenty-seven eyelids (15 patients) were allocated to G1 and 20 eyelids (12 patients) to G2. On average, surgery lasted 37.46 +/- 5.73 min in G1 and 32.70 +/- 8.39 min in G2. Based on the margin reflex distance, 93% of the eyelids in G1 and 85% in G2 were within the normal range after surgery. The corresponding figures for lid contour were 63 and 55%. Both groups displayed significant improvement in OSDI scores. No significant difference was observed in the overall comparison. The two surgical techniques were equally effective in the treatment of UER from GO. Postoperative contour outcomes were considerably worse in patients with severe UER than in patients with mild or moderate UER, regardless of group.
- Clinical and Radiological Evaluation of Periocular Infantile Hemangioma Treated With Oral Propranolol: A Case Series(2018) GINGUERRA, Maria Antonieta; SAITO, Osmar; FERNANDES, Jose Byron V. D.; CASTRO, Deborah S.; MATAYOSHI, SuzanaPURPOSE: To evaluate the efficacy of propranolol (3 mg/kg/day) in the treatment of periocular infantile hemangioma (IH) based on clinical and radiological findings. DESIGN: Prospective interventional case series. METHODS: Study of previously untreated infants with IH conducted at the ophthalmology outpatient service of HC-FMUSP (Brazil). The patients were submitted to a complete ophthalmologic examination, gray-scale and Doppler ultrasonography, and nuclear magnetic resonance imaging. Lesion regression was evaluated clinically and radiologically during follow-up. The sample consisted of potentially amblyogenic and disfiguring lesions. The dose was increased at weekly intervals, from 0.5 mg to 3 mg/kg/day. The age at onset of treatment was 228 months. Follow-up lasted up to 48 months. RESULTS: Nine infants with periocular IH were treated with propranolol (oral) for 2-12 months (mean: 7.1 months). Clinical regression (attenuation of color and reduction in size) was observed in 88% during the first days of treatment. Partial recurrence was observed during follow-up in a patient treated for 6 months. On Doppler ultrasonography, during the first 6 months of treatment lesion volume and vascular density decreased while the arterial resistivity index (RI) increased, followed by a decline. CONCLUSION: Propranolol at 3 mg/kg/day was clinically and radiologically efficacious against deep IH in the proliferative stage, with no recurrence in patients treated for 12 months. RI might help determine when treatment can be safely interrupted.
- Uso da estereofotogrametria para mensuração do volume da anatomia externa da face: revisão sistemática(2018) MIRANDA, RICARDO EUSTACHIO DE; MATAYOSHI, SUZANA; BRABO, JANAINA LUCILA; MIYOSHI, LETÍCIA HARUMIABSTRACT Introduction: Photographic documentation is important in several medical specialties, such as plastic surgery. Two-dimensional photography has limitations in capturing structure depth and volume, requiring other instruments to evaluate these changes. Several technologies have been developed for three-dimensional analysis of objects, of which stereophotogrammetry uses computerized analysis of two or more simultaneous photographs of the object to produce a three-dimensional geometric model. The advantages of stereophotogrammetry include lower cost, portability, absence of radiation, and speed of image capture. The aim of the present study was to perform a bibliographic review evaluating the use and accuracy of stereophotogrammetry for measuring the volume of facial structures. Methods: Using a combination of MeSH keywords and free terms, a search was performed in the Cochrane Library and MEDLINE databases. The search included all articles published on or before May 2018. Results: 2,213 studies were initially retrieved using this search strategy. Of these, 27 studies were selected based on the eligibility criteria, of which 21 were non-randomized case studies and 6 were randomized clinical trials. The methodological quality of the studies varied between 50 and 67%, on a grading scale from 0 to 100%. Conclusions: Stereophotogrammetry is a promising technology that is increasingly being used to check for facial volume variations with high accuracy and reproducibility. More studies with higher methodological quality are needed for evaluating the accuracy and use of stereophotogrammetry for facial volume evaluations.

- Non-surgical treatment for eyelid retraction in thyroid eye disease (TED)(2018) GRISOLIA, Ana Beatriz Diniz; COUSO, Ricardo Christopher; MATAYOSHI, Suzana; DOUGLAS, Raymond S.; BRICENO, Cesar AugustoThyroid eye disease (TED) is an autoimmune condition with an unpredictable course that may lead to permanent facial disfigurement. Eyelid retraction is one of the most common findings, and frequently demands attention due to ocular exposure and impaired cosmesis. Surgical treatment remains the most effective option, but there is a role for temporary corrections during the active phase of the disease, as well as in patients who are poor surgical candidates. The aim of this review is to describe the non-surgical modalities currently available for treatment of eyelid malposition in TED. The authors have focused on the use of hyaluronic acid, triamcinolone injections and botulinum toxin type A as non-surgical treatment alternatives, paying special attention to dosing, technique, efficacy and duration of effect. Non-surgical treatment modalities may represent viable in cases where surgical correction is not an option. Although temporary, these modalities appear to be beneficial for ocular exposure remediation, improving quality of life and broadening our therapeutic arsenal.
