Abstract(s)
Com o intuito de demonstrar os conhecimentos adquiridos ao longo do estágio, foi
elaborado um relatório com três casos de áreas distintas.
O primeiro caso sobre a área de patologia ocular refere-se à suspeita de Oclusão da Veia
Central da Retina (OVCR). A OVCR tem maior prevalência em idosos, afetando ambos
os sexos, todas as etnias e normalmente é unilateral. O diagnóstico diferencial é
essencial para o seu tratamento. Os tratamentos com maior sucesso são a aspirina,
anticoagulação sistémica, hemodiluição isovolêmica e plasmaférese.
O segundo caso a ser abordado sobre a área de contactologia, é adaptação de lente de
contacto mini-escleral em queratocone. O queratocone é uma patologia da córnea, não
inflamatória, que se caracteriza por uma ectasia progressiva, tornando a córnea mais
fina e com a forma de cone. Quase sempre, é uma condição bilateral e assimétrica. O
queratocone pode progredir até aos 40 anos de idade, afeta ambos os sexos e todas as
etnias. Está classificado por diferentes estágios. Relativamente à sua forma, pode-se
classificar em queratocone mamilar, oval e queratoglobus. O tratamento não cirúrgico
pode ser feito através de lentes oftálmicas e/ou lentes de contacto.
O último caso é sobre a área de Visão Binocular (VB), retrata um caso de insuficiência
de convergência (IC). A IC é um distúrbio visual binocular no qual a convergência para
um objeto próximo é reduzida. Caracteriza-se por um ponto próximo de convergência
afastado (PPC), por uma exoforia maior ao perto do que ao longe, por uma acomodação
e Convergência Acomodativa (A/CA) baixa e por medidas diretas ou indiretas de
Vergências Fusionais Positivas (VFP) baixas. O tratamento sequencial passa por
ergonomia e higiene visual, correção ótica da ametropia, terapia visual, e por fim
prescrição de prismas.
In order to show the knowledge acquired during the internship, a report was prepared with three cases from different areas. The first case in the area of ocular pathology refers to the suspected Central Retinal Vein Occlusion (CRVO). CRVO has a higher prevalence in the elderly, affecting both genders, all ethnicities and is usually unilateral. The differential diagnosis is essential for its treatment. The most successful treatments are aspirin, systemic anticoagulation, isovolemic hemodilution and plasmapheresis. The second case to be addressed in the area of contactology is the adaptation of a miniscleral contact lens in keratoconus. Keratoconus is a non-inflammatory corneal disease characterized by progressive ectasia, making the cornea thinner and cone-shaped. It is almost always a bilateral and asymmetrical condition. Keratoconus can progress up to the age of 40, affects both sexes and all ethnicities. It’s classified by different stages. Regarding the shape, it can be classified as nipple keratoconus, oval keratoconus and keratoglobus. Non-surgical treatment can be done through Ophthalmic Lenses and/or Contact Lenses. The last case that is focused in this report is about the area of Binocular Vision (BV) portrays a case of convergence insufficiency. This is a binocular visual disorder in wich convergence to a nearby object is reduced. It is characterized by a distant near point of convergence (PPC), by a greater exophoria at close than at a distance, by a low accommodation and Accommodative Convergence (A/CA) and by direct or indirect measures of Positive Fusion Vergencies (VFP) casualties. The sequential treatment goes through ergonomics and visual hygiene, optical correction of ametropia, visual therapy, and finally, if justified, prescription of prisms.
