ABSTRACT Introduction: To obtain fundoscopy images through portable and low-cost equipment using artificial intelligence to assess the presence of DR. Methods: Fundus images of diabetic patients’ eyes were obtained by using a smartphone coupled to a device with a 20D lens. By using artificial intelligence (AI), the presence of DR was classified by a binary algorithm. Results: 97 ocular fundoscopy images were evaluated (45 normal and 52 with DR). Through AI diagnostic accuracy around was 70% to 100% in the […]

ABSTRACT This report was aimed at presenting a case of neurotrophic keratitis and concomitant SARS-CoV-2 infection in a patient who has recently undergone a corneal DALK transplant. One month after corneal transplantation with adequate corneal epithelialization, the patient presented neurotrophic keratitis with a torpid course of the corneal transplant coinciding with a SARS-CoV-2 infection, with an excessive host immune response. In addition, the patient presented a re-positivization of nasopharyngeal polymerase chain reaction of SARS-CoV-2 with past disease after starting treatment […]

ABSTRACT Pigment dispersion syndrome is associated with clinical features such as Krukenberg’s spindles, trabecular pigmentation, Scheie’s stripe and Zentmayer’s ring. Another less common feature of this syndrome is retrolental pigment deposits due to anterior hyaloid detachment or a defect in the Wieger’s ligament. We present two cases of pigment deposits on the posterior lens capsule. In both cases, there is bilateral dispersion of pigment throughout the anterior segment. The retrolental deposits are unilateral in the first case and bilateral in […]

ABSTRACT Objective: To identify the profile of human ocular tissue donors in the area covered by the Eye Bank of Paraíba (PB), highlighting the impact of positive serology for hepatitis B (anti-HBc) in the disposal of tissues for transplantation. Methods: This is a cross-sectional that uses data from the Eye Bank of Paraíba (PB) between January 2013 and December 2022. Data on origin, age, sex, cause of death, time between death and enucleation, serological results, and reason for discarded donor […]

ABSTRACT The purpose of this study was to report the ocular changes observed after a bee sting with a stinger retained in the cornea. We show the treatment and outcome of an unusual corneal injury and its pathogenesis. This is a case report and literature review of ocular injuries caused by bee stings. A 63-year-old female patient sought emergency ophthalmic care because of a bee sting on the cornea of her right eye six days before. She complained of blurred […]

No momento em que escrevo este editorial, estamos impactados por tudo o que ocorre no mundo, especialmente na Ucrânia, em Israel e no Brasil, onde uma guerra urbana ocorre em vários locais quase diariamente. Poderia comentar os artigos publicados nesta edição da Revista Brasileira de Oftalmologia ou abordar avanços na oftalmologia, ou algum tópico referente ao que vi ou fiz nestes últimos 50 anos em que presenciei tantos fatos acontecendo na medicina. […]

ABSTRACT The characteristic optical coherence tomography finding in solar maculopathy is a well-defined outer retinal hyporeflective space primarily involving the photoreceptor inner and outer segment layers. This typical optical coherence tomography image may be present in a few other pathologies, which currently constitute their main differential diagnoses. Our study shows the report of 12 eyes of 6 patients treated at the Hospital de Olhos do Paraná, presenting their clinical history and diagnostic images, with the purpose of comparing the findings […]

ABSTRACT Keratopigmentation was first recorded many centuries ago by the philosopher Galeno, as a strategy used for the aesthetic treatment of patients with leukomas. Corneas with leucoma are pathological and often intolerant of cosmetic contact lenses or ocular prostheses, with complaints of excessive discomfort provided by the irregular corneal surface being common. Therefore, keratopigmentation is an alternative for the aesthetic improvement of patients with corneal opacities. We describe the case of a 39-year old male patient, who presented early depigmentation […]
