A 34-year-old man presented with pain and blurring vision in the right eye for 24 hours. The best-corrected visual acuity was 9/10 in the right eye. Slit-lamp examination of the right eye revealed conjunctival injection, three white granulomatous corneal precipitates (), one of them behind a stromal infiltrated area. A white tyndall effect in the anterior chamber at one cross and ocular hypertension at 50 mmHg were noticed. Gonioscopy shows a 360° open angle with a flat iris insertion root. […]

ABSTRACT This report aims to present classical and pathognomonic ocular changes, sequelae, and complications in a patient with Virchowian leprosy diagnosed in 2008 and undergoing their first ophthalmological evaluation in 2023. Leprosy is an infectious disease caused by Mycobacterium leprae, more prevalent in underdeveloped countries, with Brazil being the second most prevalent country worldwide. Cutaneous and peripheral nerve involvement are very common. However, ocular manifestations, which most frequently occur in patients with a long course of the disease in the […]

ABSTRACT Objective: To analyze the morphological and functional long-term outcomes of amniotic membrane transplantation after ocular surface chemical burns. Methods: This prospective study analyzed 7 patients who suffered from severe ocular surface burn and underwent amniotic membrane transplantation from 2015 to 2020 in Hospital de Clínicas – Universidade Federal do Paraná. Results: Out of the seven patients, six (85.7%) suffered unilateral burn and one (14.3%) suffered bilateral burn. Five of them had alkali burns (71.4%), one had acid burn (14.3%) […]

ABSTRACT Objective To analyze the clinical profile of patients with ocular surface squamous neoplasms (OSSN). Methods The main risk factors involved in the genesis of the ocular surface squamous neoplasms, the clinical features, and the behavioral habits associated were evaluated. This historical cohort study included 80 patients with anatomopathological diagnosis of OSSN who were treated between 2010-2020 at a reference hospital in oculoplastic and anterior segment in Santa Catarina. The clinical data and outcomes were evalated through the analysis of […]

ABSTRACT Objective: To assess if early alterations detected by Pentacam in children suffering from mild ocular allergy are suggestive of ectasia. Methods: A retrospective analysis of 49 medical records of patients of both sexes, aged between 3 and 14 years was performed. In this sample, 31 children suffered from grade I ocular allergy, and 18 presented no signs or symptoms of ocular allergy and comprised the control group. Several Pentacam indexes were evaluated. Results: A statistically significant association was found […]

Abstract Objective: To evaluate the clinical effectiveness of amniotic membrane transplantation for ocular surface reconstruction. Methods: Prospective study including 23 eyes of 21 patients who underwent amniotic membrane transplantation at Hospital de Clínicas da Universidade Federal do Paraná (HC-UFPR) and at Cirurgia e Diagnose em Oftalmologia do Paraná (CDOP) clinic, located in Curitiba, PR, Brazil, from may 2015 to july 2019. The amniotic membrane was collected from elective and term cesarean delivery, and conserved in preservation medium and glycerol 1:1, […]

The methodology currently used for interpretation of the cornea and anterior segment tomography for the diagnosis of corneal ectasia. Description of the clinical interpretation of anterior segment tomography (Pentacam – Oculus, Wetzlar, Germany); case report of the ectopia lentis demonstrating the importance o evaluation of the cornea and anterior segment of the keratoconus. We excluded the disease, analyzing the tomographic analysis of rates of ectasia and observe an asymmetry between nasal and temporal sides in assessing the depth map of […]

Toxic anterior segment syndrome is acute inflammatory reaction caused by a noninfectious substance that enters the anterior segment, resulting in extracellular damage with necrosis and apoptosis during an immune response. We have the report of a case of toxic anterior segment syndrome (TASS), in which the authors seek to emphasize the most common causes of the appearance of these syndrome. They point out the care that must be taken in the process of sterilization of surgical material, in addition to […]
