De acordo com a Organização Mundial de Saúde, a catarata é a principal causa de cegueira e deficiência visual em todo o mundo. No entanto, a etiologia das cataratas frequentemente permanece desconhecida. Este relato descreve o desenvolvimento de catarata cortical em um paciente após Síndrome oculoglandular de Parinaud causada pelo fungo Sporothrix schenckii.

Recurrent multifocal conjunctival melanoma originated from preexisting nevus is extremely rare: it occurs in one out of five million individuals. The investigation of this disease is extremely important due to its potential lethality. Thus, this study aims to describe a case of recurrent multifocal conjunctival melanoma originated from preexisting pigmented nevus, which occurred in the city of Patos de Minas, state of Minas Gerais. This is a case study and literature review. Histopathological diagnosis and early staging of the conjunctival […]

Cavernous sinus thrombosis (CST) is a rare condition, usually results from a late complication of an infection of the paranasal sinuses. Other causes include prothrombotic disorders, anemia and trauma. The signs and symptoms are extremely varied and nonspecific, being the diagnosis made through magnetic resonance imaging (MRI). The authors present a 75-year-old woman, admitted in the emergency room complaining of ocular pain in the right eye (RE), red eye and frontal headache. She presented on ophthalmic examination of the RE: […]

Iodotherapy represents the radioactive iodine therapy. The beta radiation emitted by radioactive iodine are particles that will be stored in the thyroid tissue destroying cancer cells that were left after surgery (thyroidectomy). It is important to emphasize a possible deleterious effect of therapy which affects the mucosa of the lacrimal system which results in a process of vascular inflammation and scarring producing disorders hypovascular, hypocellular and hypoxic.

The first step for design a scientific study is to raise doubts which at that moment could not be solved with the information available in literature (a gap in knowledge). In clinic surveys, one should expect that the response to that doubt is to contribute to improve medical practice. The following step is to determine what population will be investigated. For example, when evaluating the efficacy of an intraocular lens (IOL) with yellow pigmentation in the prevention of macular degeneration […]

Cataract surgery is one of the most commonly-performed surgeries in the world, providing benefits to patients(1) and society as a whole(2). Despite technological advances in intraocular lenses (IOLs) to correct spherical aberrations(3), presbyopia and astigmatism(4), there are still cases where IOLs need to be explanted due to opacification of their materials(5) […].

Purpose: To evaluate the efficacy and reliability of a low-energy femtosecond laser with a high repetition rate for construction of deep anterior donor corneal lamellae. Methods: This was a prospective laboratory investigation. Twenty-five human corneal buttons were femtosecond laser cut to create thick anterior lamellae (diameter, 10mm; thickness, 500µm). The laser cuts were made using an LDV® femtosecond laser in a Ziemer® anterior chamber. To obtain a better edge, the lamellae were trephined with an 8mm trephine (Katena®). The central […]

Objetivo: Avaliar a eficácia e segurança de um laser de femtossegundo de baixa energia e alta taxa de repetição para confecção de lamelas corneanas doadoras anteriores profundas. Métodos: Este é um estudo prospectivo de investigação laboratorial. Vinte e cinco botões corneanos foram cortados com laser de femtossegundo para criar lamelas corneanas doadoras anteriores profundas (diâmetro, 10mm; espessura, 500µm). O corte a laser foi realizado com femtosecond laser LDV® na câmara anterior artificial da Ziemer®. Para obter-se uma melhor borda, as […]
