Department of Ophthalmology, Otorhinolaryngology and Head and Neck Surgery, Faculty of Medicine of Ribeirão Preto, Universidade de São Paulo, Ribeirão Preto, SP, Brazil.

Degenerative retinal diseases such as retinitis pigmentosa, Stargardt's macular dystrophy, and age-related macular degeneration are characterized by irreversible loss of vision due to direct or indirect photoreceptor damage. No effective treatments exist, but stem cell studies have shown promising results. Our aim with this review was to describe the types of stem cells that are under study, their effects, and the main clinical trials involving them. Read More

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

Mechanisms and biomarker candidates in pterygium development.

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.

Ultrastructural changes detected using swept-source optical coherence tomography in severe vitreopapillary traction: a case report.

Arq Bras Oftalmol 2019 30;82(6):517-521. Epub 2019 Sep 30.

Division of Ophthalmology, School of Medicine, Universidade de São Paulo, São Paulo, SP, Brazil.

Vitreopapillary traction is an uncommon condition characterized by strong adhesion and the traction of the posterior hyaloid onto the optic disc and peripapillary retina, leading to optic disc elevation and visual loss. An 85-year-old man presented with a 6-month history of slow, progressive visual loss in the left eye along with optic disc edema. Swept-source optical coherence tomography B-scans revealed circumpapillary anterior-posterior persistent traction of dense vitreous strands onto the optic disc. Read More

Post-laser in situ keratomileusis interface Arthrographis kalrae keratitis.

Arq Bras Oftalmol 2020 Jan-Feb;83(1):65-68

Ophthalmology Institute Costa del Sol, Fuengirola, Málaga, Spain.

We describe a case of keratomycosis caused by Arthographis kalrae after excimer laser keratomileusis. A 38-year-old female developed stromal keratitis eight weeks after refractive surgery. She developed severe corneal stromal infiltration and mild anterior segment inflammation, which could not be treated with topical voriconazole 1%, but topical natamycin 5% ameliorated her condition.

Prosthesis-socket volume imbalance and dermofat graft rehabilitation in patients with an anophthalmic socket.

Arq Bras Oftalmol 2020 Jan-Feb;83(1):33-38

Department of Ophthalmology, Sisli Hamidiye Etfal Training and Research Hospital, Istanbul, Turkey.

Purposes: To identify problems caused by prosthesis-socket volume imbalances in anophthalmic sockets; and to evaluate rehabilitation with dermofat graft as a solution.

Methods: We retrospectively reviewed medical records of patients operated in our clinic (between May 2011 and June 2016) with dermofat grafts to treat anophthalmic socket-related problems. During the preoperative examinations, ophthalmologists recorded the presence of eyelid problems due to the socket volume deficit, upper and lower fornix deficiency, deepening in the upper eyelid sulcus, epiphora and secretion, lower eyelid laxity, ptosis, entropion, and ectropion.

Upper eyelid contour symmetry measurement with Bézier curves.

Arq Bras Oftalmol 2020 Jan-Feb;83(1):28-32

Department of Ophthalmology, School of Medicine of Ribeirão Preto, Universidade de São Paulo, Ribeirão Preto, SP, Brazil.

Purpose: The purpose of the present work is to measure the interocular upper lid contour symmetry using a new method of lid contour quantification.

Methods: The Bézier curve tool of the Image J software was used to extract the right and left upper eyelid contours of 75 normal subjects. Inter-observer variability of 29 right lid contours obtained by two independent observers was estimated using the coefficient of overlap of two curves and an analysis of the differences of the contour peak location.

Carnitine analysis in pterygium.

Arq Bras Oftalmol 2020 Jan-Feb;83(1):5-10

Department of Ophthalmology, Harran University Faculty of Medicine, Şanlıurfa, Turkey.

Purpose: The aim of the present study was to measure the free carnitine and acylcarnitine levels in pterygium tissue and normal conjunctival tissue at the metabolomics level using tandem mass spectrometry.

Methods: In this prospective, clinical randomized study, pterygium tissues and normal conjunctival tissues taken during pterygium excision with autograft were compared regarding their free carnitine and acylcarnitine profiles. After tissue homogenization, carnitine levels were measured using tandem mass spectrometry. Read More

Anterior chamber characteristics assessed by rotating Scheimpflug imaging in patients with retinitis pigmentosa.

Arq Bras Oftalmol 2019 12;82(6):507-510. Epub 2019 Sep 12.

Department of Ophthalmology, Kayseri Research and Training Hospital, Kayseri, Turkey.

Purpose: The aim of this study was to evaluate anterior segment parameters and corneal aberrations in patients with retinitis pigmentosa using Scheimpflug imaging and to compare the findings with those for healthy controls.

Methods: This single-center, case-control study included patients diagnosed with retinitis pigmentosa who were followed up at the Department of Ophthalmology of Kayseri Training and Research Hospital between February and June 2018. Age- and sex-matched healthy individuals with no known ophthalmologic disease formed the control group. Read More

Prevalence of cataract complications in patients with pseudoexfoliation syndrome in Northwestern Spain.

Arq Bras Oftalmol 2019 12;82(6):495-500. Epub 2019 Sep 12.

Pharmacy Service, Hospital de Dénia, Alicante, Spain.

Purpose: To assess the relationship between pseudoexfoliation syndrome and incidence of complications and related clinical factors in patients undergoing cataract surgery.

Methods: We conducted a retrospective cohort study of 503 of 551 patients who underwent phacoemulsification surgery over 2 years in a health care district in Northwest Spain. In total, 120 of 681 eyes undergoing the procedure had pseudoexfoliation syndrome. Read More

Validation of ROPScore to predict retinopathy of prematurity among very low birth weight preterm infants in a southern Brazilian population.

Arq Bras Oftalmol 2019 12;82(6):476-480. Epub 2019 Sep 12.

Department of Ophthalmology, Faculdade de Medicina, Universidade Federal do Rio Grande do Sul, Porto Alegre, RS, Brazil.

Purposes: To evaluate the sensitivity, specificity, and cutoff points for the ROPScore, which is based on cumulative risk factors for the prediction of retinopathy of prematurity (ROP), in a population of very low birth weight (BW) preterm infants in southern Brazil.

Methods: The medical records of all preterm infants with a very low birth weight ≤1,500 g and/or gestational age ≤32 weeks screened for retinopathy of prematurity in two Brazilian institutions between August 2009 and December 2015 were retrospectively reviewed. ROPScores were calculated using birth weight and gestational age, the use of oxygen therapy with mechanical ventilation, and weight gain proportional to birth weight, as measured at postpartum week six and the need for blood transfusions.
