Purpose: Many reports have indicated an association between thyroid dieases and primary Sjögren’s syndrome (pSS). The aim of our study was to evaluate the outcomes of the tests used for dry eye diagnosis and salivary gland involvement in patients with autoimmune thyroiditis. Methods: Forty-two patients (group 1) with autoimmune thyroid disease and 30 controls (group 2) were selected. Tear film break up time, Schirmer I test, Schirmer II test, ocular staining with 1% rose Bengal and salivary gland cintilography were […]

Objective: To identify microscopic morphological alterations in the surface of silicone tubes used for intubation of the lachrymal system after exposure to ophthalmological lubricants. Methods: Experimental, descriptive and longitudinal study consisted of the application of ophthalmological lubricants in silicone tubes. The tubes were divided in: Group 1 (Cylocort®), 2 (Epitezan®), 3 (Labcaína®), 4 (Liposic®), 5 (Maxinom®) and 6 (Vista Gel®). One tube was not exposed to any lubricant, used as control. The tubes were observed and photographed after 2 hours, […]

Purpose: To report the anatomic and functional outcome in patients with severe visual loss after acute massive submacular hemorrhage secondary to retinal arterial macroaneurysm submitted to vitrectomy and subretinal recombinant tissue plasminogen activator injection. Methods: Retrospective, observational, case-series of 4 eyes of 4 patients submitted to pars plana posterior vitrectomy (ppV) combined with internal limiting membrane (ILM) removal and subretinal recombinant tissue plasminogen activator (rtPA-12.5 mg/0.1 ml) injection with dilute (20%) sulfur hexafluoride (SF6) gas in the vitreous cavity of […]

Objective: To detect the presence of lymphatic vessels in the cornea through histopathological examination, trying to identify findings that are most commonly found with the presence of these vessels in this tissue. Methods: Retrospective descriptive study of human corneal buttons with lymphangiogenesis. Tissues were obtained from penetrating keratoplasty in the period between the years 2006 and 2013. A medical record review was conducted looking for information about sex, age and graft etiology. Results: 89 corneal buttons were included, out of […]

Purpose: To evaluate the postoperative results when using the toric IOL during phacoemulsification. Methods: Retrospective cohort based study on the 95 eyes of 67 patients, selected by a census. Analyzed patients with cataracts who had undergone phacoemulsification placement with AcrySof® toric IOL from january 2010 to december 2012. For analysis purposes, it was considered successful when the residual astigmatism was d”0.75 diopters. The Wilcoxon test for related samples was used to compare non-parametric samples, while the Student T test was […]

Objective: To analyze two methods of reducing conjunctivalmicrobiota in patients undergoing cataract surgery. Methods: A clinical trial with a convenience sample of 57 patients diagnosed with senile cataract (57 eyes) who underwent phacoemulsification with intraocular lens implantation in Recife from 2011 to 2013. Patients were divided into two groups: ATB (27 eyes) in which was instilled antibiotic eye drops (gatifloxacin 0.3%) and ASS (30 eyes) with antiseptic eye drops (iodopovidine 5%); both medications were instilled three times (one drop every […]

Objective: Demonstrate the Brimonidine effect over Retinal Spreading Depression (SD). Brimonidine is an alpha-2–adrenergic receptor agonist, used in the management of glaucoma. Alpha2-agonists have been shown to be neuroprotective in various experimental models, however the molecular and cellular targets leading to these actions are still poorly defined. The SD of neuronal electric activity is a wave of cellular massive sustained depolarization that damages the nervous tissue. Local trauma, pressure, ischemic injuries and other chemical agents as high extracellular potassium concentration […]

Purpose: To measure and compare size and shape parameters of femtosecond laser capsulotomy with manually continuous curvilinear digital guided capsulorhexis (CCC) and their refractive outcomes. Methods: Laser capsulotomies in 40 eyes of 40 patients were performed using LenSx femtosecond laser device (Alcon, Forthworth, US) and its results were compared with the CCC digital guided carried out in 40 eyes of 40 patients using the Callisto Eye digital image system (Zeiss, Germany). Capsulorhexis circularity, shape and capsule overlap were measured using […]
