Fluocinolone Acetonide 0.19 mg Implant in Patients with Cystoid Macular Edema D...
Marques, Joao Heitor; Abreu, Ana Carolina; Silva, Nisa; Meireles, Angelina; Pessoa, Bernardete; Beirão, JoãoBackground: Cystoid macular edema (CME) due to Irvine-Gass syndrome (IGS) is one of the common causes of painless visual impairment post-cataract extraction. The treatment of recurrent cases remains unstandardized. Objective: To evaluate the effectiveness and safety of fluocinolone acetonide intravitreal implant (0.2 µg/day; ILUVIEN®) in the off-label treatment of recurrent CME due to IGS. Methods: Retrospectiv...
Corneal Biomechanical Assessment with Ultra-High-Speed Scheimpflug Imaging Duri...
Baptista, Pedro Manuel; Ambrósio Jr, Renato; OLIVEIRA, LUIS; Menéres, Pedro; Beirão, JoãoBackground: In recent years, increasing interest has arisen in the application of data from corneal biomechanics in many areas of ophthalmology, particularly to assist in the detection of early corneal ectasia or ectasia susceptibility, to predict corneal response to surgical or therapeutic interventions and in glaucoma management. Technology has evolved and, recently, the Scheimpflug principle was associated w...
Expert consensus recommendations to improve diagnosis of ATTR amyloidosis with ...
Adams, David; Ando, Yukio; Beirão, João; Coelho, Teresa; Gertz, Morie A.; Gillmore, Julian D.; Hawkins, Philip N.; Lousada, Isabelle; Suhr, Ole B.Amyloid transthyretin (ATTR) amyloidosis with polyneuropathy (PN) is a progressive, debilitating, systemic disease wherein transthyretin protein misfolds to form amyloid, which is deposited in the endoneurium. ATTR amyloidosis with PN is the most serious hereditary polyneuropathy of adult onset. It arises from a hereditary mutation in the TTR gene and may involve the heart as well as other organs. It is critica...
Severe ocular involvement in hereditary gelsolin amyloidosis
Silva, Nisa; Beirão, JoãoHereditary gelsolin amyloidosis is a rare subtype of hereditary systemic amyloidosis. An old male presented with the characteristic triad of symptoms, including bilateral facial palsy, cutis laxa, and corneal lattice amyloidosis. The diagnosis was confirmed by the detection of the mutation in gelsolin gene located on chromosome 9. Although the presenting symptoms were highly suggestive of the disease, reports o...
Intravitreal Ranibizumab or Aflibercept After Bevacizumab in Diabetic Macular E...
Pessoa, Bernardete; Malheiro, Luisa; Carneiro, Inês; Monteiro, Sílvia; Coelho, João; Coelho, Constança; Figueira, João P; Meireles, AngelinaAim: To evaluate the efficacy of switching from bevacizumab to ranibizumab or aflibercept in eyes with diabetic macular edema (DME) unresponsive to bevacizumab. Methods: Single-center retrospective comparative study of patients with DME unresponsive to intravitreal bevacizumab that was switched to ranibizumab or aflibercept. Best-corrected visual acuity (BCVA) and central foveal thickness (CFT) were analysed pri...
Choroidal Blood Flow After Intravitreal Ranibizumab in Vitrectomized and Non-Vi...
Pessoa, Bernardete; Marques, Joao Heitor; Leite, João; Silva, Nisa; José, Diana; Coelho, Constança; Figueira, João P; Meireles, Angelina; Beirão, JoãoAim: Diabetic retinopathy staging system and progression predictors are soon to be considered insufficient for ophthalmologic practice. Given the growing evidence of the role of choroidal dysfunction, our purpose was to assess choroidal vascular changes with intravitreal ranibizumab (RBZ) treatment in diabetic macular edema (DME). Methods: This was a prospective longitudinal cohort study. The study included DME...
Challenging Clinical Cases – A Walk Through Supplemental Therapy with Intravitr...
Pessoa, Bernardete; Beirão, João; Meireles, Angelina; Menéres, PedroPurpose: There are limited published data regarding the use of supplemental intravitreal therapies in patients with diabetic macular edema (DME) following treatment with the 0.19 mg fluocinolone acetonide (FAc; ILUVIEN®) intravitreal implant. The aim of this report was to analyze five challenging eyes that required supplemental therapies after treatment with the FAc implant. Methods: This is a retrospective cas...
Enzymatic vitreolysis for the treatment of tractional diabetic macular edema
Pessoa, Bernardete; Coelho, João; Coelho, Constança; Monteiro, Sílvia; Abreu, Carolina; Figueira, João; Meireles, Angelina; Beirão, JoãoBackground: A new approach to address focal vitreomacular adhesion in patients with diabetic macular edema may control and stabilize diabetic macular edema with fewer anti-vascular endothelial growth factor injections. Objectives: The aim of this study was to demonstrate that diabetic macular edema can be improved by inducing the release of a vitreomacular adhesion, with less than 2500 μm, with enzymatic vitreo...
Meretoja's Syndrome: Lattice Corneal Dystrophy, Gelsolin Type
Casal, I.; Monteiro, S.; Abreu, C.; Neves, M.; Oliveira, L.; Beirão, JoãoLattice corneal dystrophy gelsolin type was first described in 1969 by Jouko Meretoja, a Finnish ophthalmologist. It is caused by an autosomal dominant mutation in gelsolin gene resulting in unstable protein fragments and amyloid deposition in various organs. The age of onset is usually after the third decade of life and typical diagnostic triad includes progressive bilateral facial paralysis, loose skin, and l...
Aqueous humor erythropoietin levels in open-angle glaucoma patients with and wi...
Beirão, João; Moreira, L.; Oliveira, J.; Menéres, M.; Pessoa, Bernardete; Matos, M.; Costa, P.; Torres, P.; Beirão, I.Purpose: Glaucoma is the leading cause of irreversible blindness in familial amyloidotic polyneuropathy (FAP) patients. Erythropoietin (EPO) is a cytokine that has been shown to play a role in neuroprotection and is endogenously produced in the eye. EPO levels in the aqueous humor are increased in eyes with glaucoma. In this study, we evaluated the EPO concentration in the aqueous humor of FAP and non-FAP patie...
