R.- Radiographic Characteristics of Adrenal Masses Preceding the Diagnosis of Adrenocortical Cancer(2015) NOGUEIRA, T. M.; LIROV, R.; CAOILI, E. M.; LERARIO, A. M.; MILLER, B. S.; FRAGOSO, M. C. B. V.; DUNNICK, N. R.; HAMMER, G. D.; ELSE, T.Incidentally discovered adrenal masses are common and the clinical evaluation and surveillance aims to diagnose hormone excess and malignancy. Adrenocortical cancer (ACC) is a very rare malignancy. This study aims to define the imaging characteristics of adrenal tumors preceding the diagnosis of ACC. Patients with prior (> 5 months) adrenal tumors (< 6 cm) subsequently diagnosed with ACC were identified in a large registry at a tertiary referral center. Retrospective chart and image review for patient characteristics and initial, interval, and diagnostic imaging characteristics (size, homogeneity, borders, density, growth rate, etc.) was conducted. Twenty patients with a diagnosis of ACC and a prior adrenal tumor were identified among 422 patients with ACC. Of these, 17 patients were initially imaged with CT and 3 with MR. Only 2 of the 20 patients had initial imaging characteristics suggestive of a benign lesion. Of initial tumors, 25 % were < 2 cm in size. Surveillance led to the diagnosis of ACC within 24 months in 50 % of patients. The growth pattern was variable with some lesions showing long-term stability (up to 8 years) in size. In conclusion, antecedent lesions in patients with a diagnosis of ACC are often indeterminate by imaging criteria and can be small. Surveillance over 2 years detected only 50 % of ACCs. Current practice and guidelines are insufficient in diagnosing ACCs. Given the rarity of ACC, the increased risk and health care costs of additional evaluation may not be warranted.
- Stellate nonhereditary idiopathic foveomacular retinoschisis resolution after vitreomacular adhesion release(2021) NOGUEIRA, T. Machado; COSTA, D. de Souza; ISENBERG, J.; REZENDE, F. A.Purpose: To present a case of stellate nonhereditary idiopathic foveomacular retinoschisis (SNIFR) resolution associated with vitreomacular adherence (VMA) release and propose a potential contributing association between SNIFR and vitreomacular interactions. Observations: A 67-year-old female patient was diagnosed and followed for SNIFR in OD with spectral-domain optical coherence tomography (SD-OCT) scans at presentation and subsequent visits at 3, 6, 16 and 22 months. VMA and foveomacular retinoschisis remained unchanged on SD-OCT during the first 6 months of the follow-up. At 16-month follow-up visit, SD-OCT revealed VMA release and an important improvement of the macular schisis. At 22 months of follow-up, SNIFR cavities completely resolved in the presence of posterior hyaloid separation from the macular area without any adjunct treatment. The authors could not identify any other possible cause to justify the resolution of SNIFR other than VMA release in this case. Patient did not undergo any treatment for OD other than phacoemulsification 3 months after initial visit. Conclusion: The present case illustrates with SD-OCT scans a possible association between SNIFR resolution and VMA release, highlighting a potential tractional component of the posterior vitreous on the internal limiting membrane and consequent glial cells stretching with schisis formation. © 2021
- VITRECTOMY for STELLATE NONHEREDITARY IDIOPATHIC FOVEOMACULAR RETINOSCHISIS ASSOCIATED with OUTER RETINAL LAYER DEFECT(2022) MORAES, B. R. M.; FERREIRA, B. F. A.; NOGUEIRA, T. M.; NAKASHIMA, Y.; JúNIOR, H. P. P.; SOUZA, E. C.Purpose:To describe a case of stellate nonhereditary idiopathic foveomacular retinoschisis associated with outer retinal layer defect treated with pars plana vitrectomy, internal limiting membrane removal, and C3F8 tamponade.Methods:Spectral-domain optical coherence tomography (Heidelberg Engineering, Heidelberg, Germany) scans of a 46-year-old woman with unilateral stellate nonhereditary idiopathic foveomacular retinoschisis were acquired at baseline and 1, 3, 6, and 12 months after surgery.Results:Pars plana vitrectomy was performed after phacoemulsification. The vitreous was circumcised, and the internal limiting membrane was removed with a Tano brush, releasing tangential forces. The patient experienced progressive recovery of the outer retinal layers and improvement of visual acuity during follow-up.Conclusion:Stellate nonhereditary idiopathic foveomacular retinoschisis may be associated with outer retinal layer defect and severe vision loss. Pars plana vitrectomy with internal limiting membrane removal and C3F8 infusion seems to be a safe and feasible treatment in such cases, with potentially good anatomical and functional outcome. © 2022 Lippincott Williams and Wilkins.

- 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.
