Dexamethasone intravitreal implant in the crystalline lens: a case report.

Arq Bras Oftalmol 2020 06 29;83(3):242-245. Epub 2020 May 29.

Department of Ophthalmology, School of Medicine, Afyon University of Health Sciences, Afyonkarahisar, Turkey.

This report describes the therapeutic effects and outcomes of an accidental injection of an intralenticular sustained-release dexamethasone implant (Ozurdex®) in three patients with diabetic macular edema. All three patients underwent accidental injections of sustained-release intravitreal dexamethasone implants into the crystalline lens by the same surgeon. After the accidental injection of Ozurdex® into the crystalline lens, a remarkable reduction in the macular edema and an improvement in visual acuity were observed, suggesting that a positive outcome can be achieved without immediate surgery.

Centration in refractive surgery.

Arq Bras Oftalmol 2020 Jan-Feb;83(1):76-81

Unidade Paulista de Oftalmologia, São Bernardo do Campo, SP, Brazil.

The point of centration for refractive surgery is a theme of great importance that generates considerable discussion among specialists and surgeons in the field. Notably, any changes in light can alter the size of the pupil, and the visual axis of the fixation line to the fovea is unique in each patient. A variety of options have been described in the literature with respect to centration in refractive surgery, and the results differ among these methods. Read More

Unilateral intravitreal dexamethasone implant for diabetic macular edema: effect in the contralateral eye.

Arq Bras Oftalmol 2020 Jan-Feb;83(1):73-75

Wooptix S.L, Santa Cruz de Tenerife, Spain.

We describe three patients who had previous heart diseases and nonproliferative diabetic retinopathy with clinically significant diabetic macular edema. They underwent unilateral dexamethasone intravitreal implantation. Without ophthalmological treatment in the fellow eye, patients showed marked bilateral improvement in best-corrected visual acuity, optical coherence images, and macular thickness values. Read More

Reproducibility of retinal and choroidal measurements using swept-source optical coherence tomography in patients with Parkinson's disease.

Arq Bras Oftalmol 2020 Jan-Feb;83(1):19-27

Ophthalmology Department, Miguel Servet University Hospital, Zaragoza, Spain.

Purpose: To assess the reproducibility of retinal and choroidal measurements in the macular and peripapillary areas using swept-source optical coherence tomography in patients with Parkinson's disease.

Methods: A total of 63 eyes of 63 patients with idiopathic Parkinson's disease were evaluated using a three-dimensional protocol of swept-source optical coherence tomography. The following layers were analyzed: full retinal thickness, retinal nerve fiber layer, ganglion cell layer, and choroid. Read More

Reliability of endoscopic dye transit test for prediction of functional success after diode laser and external dacryocystorhinostomy.

Arq Bras Oftalmol 2020 Jan-Feb;83(1):1-4

Department of Oculoplastic Surgery, Universidade de São Paulo, São Paulo, SP, Brazil.

Purpose: To determine the reliability of the endoscopic dye transit test for the prediction of functional success after dacryocystorhinostomy.

Methods: A cross-sectional study was conducted with 50 patients who underwent external dacryocystorhinostomy Group or transcanalicular dacryocystorhinostomy Group and had anatomically patent ducts during irrigation, with a minimum 6-month follow-up. The external dacryocystorhinostomy, defined as the time from instillation of the dye into the conjunctival sac until its flow from the rhinostomy site, was performed in all patients. Read More

An innovative proposal for anophthalmic cavity reconstruction surgery with bone cement: a case report.

Arq Bras Oftalmol 2020 Jan-Feb;83(1):62-64

Universidade Estadual do Ceará, Fortaleza, CE, Brazil.

We present a patient who underwent evisceration surgery after spontaneous rupture of the ocular globe due to long-data uncontrolled glaucoma, with posterior placement of an orbital implant made of a bone cement compound based on polymethylmethacrylate as alternative materials were not available. Such a compound is characterized by excellent biocompatibility and low cost, which makes it an interesting alternative for treatment. The anophthalmic socket was successfully filled, providing proper esthetic results and favorable conditions for the posterior scleral prosthesis implantation. Read More

Mechanisms and biomarker candidates in pterygium development.

Arq Bras Oftalmol 2019 30;82(6):528-536. Epub 2019 Sep 30.

Department of Ophthalmology, Faculdade de Ciências Médicas, Universidade de Campinas, Campinas, SP, Brazil.

Pterygium pathogenesis has been mainly asso ciated with UV light exposure; however, this association remains quite controversial. The complete mechanism of pterygium also remains to be clarified. Factors such as inflammation, viral infection, oxidative stress, DNA methylation, inflammatory mediators, extracellular matrix modulators, apoptotic and oncogenic proteins, loss of heterozygosity, microsatellite instability, lymphangiogenesis, epithelial-mesenchymal cell transition, and alterations in cholesterol metabolism have been identified as causes.
