Abstract(s)
Ao longo deste relatório vou abordar vários temas como a Retinopatia Pigmentar, o Queratocone e o Excesso de Convergência. A retinopatia pigmentar é uma distrofia retiniana hereditária caracterizada pela perda de fotorreceptores e depósitos pigmentares visíveis quando se examina o fundo do olho. A forma mais comum de retinopatia pigmentar é a distrofia de cone-bastonete, na qual o primeiro sintoma é a dificuldade em condições escotópicas, seguida de perda progressiva de campo visual periférico em condições fotópicas, podendo levar depois de várias décadas à cegueira. Relativamente ao queratocone é uma desordem da córnea, não inflamatória caracterizada por protusão anterior da córnea e redução do estroma. É uma patologia geralmente bilateral muitas vezes assimétrica que provoca diminuição da acuidade visual devido ao astigmatismo irregular miópico. Por último, o excesso de convergência é uma condição em que existe uma endoforia ao perto, e uma ortoforia ou endoforia baixa a moderada ao longe. O excesso de convergência está associada a um AC/A alto e pode estar associada com a hipermetropia. A maior parte dos sintomas estão associados com a leitura, sendo as queixas mais comuns de tensão ocular e dores de cabeça depois de curtos períodos de leitura, visão desfocada, entre outros.
Throughout this report will address several topics such as retinitis pigmentosa, keratoconus and the Excess Convergence. Retinitis pigmentosa is an inherited retinal dystrophy by the loss of photoreceptors and characterized by retinal pigment deposits visible on fundus examination. The most common form of retinitis pigmentosa is a rod-cone dystrophy, in which the first symptom is night difficulty, followed by progressive loss in the peripheral visual field in daylight, and eventually leading to blindness after several decades. Relatively to qeratoconus is one of the noninflammatory corneal disorders characterized by anterior protusion of the cornea and stromal thinning. Keratoconus is usually an often asymmetric bilateral disease that causes low vision due to irregular myopic astigmatism. Finally the excess of convergence is an condition in which there is an endophoria to near, and a orthophoria or low to moderate endophoria. Excess of convergence is associated with high AC/A and can be associated with hyperopia. Most symptoms are associated with reading, and the most common complaints are ofeyestrain and headaches after short periods of reading, blurred vision, among others.
