20 questions
Question 1: Intravitreal triamcinolone can improve serous retinal detachment and macular edema associated with acute Vogt-Koyanagi-Harada syndrome.
A. Ano
B. Ne
Explanation: The study materials state that intravitreal triamcinolone can improve serous retinal detachment and macular edema associated with acute Vogt-Koyanagi-Harada syndrome.
Question 2: Which of the following signs are characteristic of the prodromal stage of Vogt-Koyanagi-Harada syndrome?
A. Headaches and deep orbital pain
B. Subretinal neovascularization
C. Tinnitus and hearing loss
D. Sunset-glow fundus
Explanation: The study materials state that the prodromal stage is characterized by headaches, deep orbital pain, tinnitus, and hearing loss. Subretinal neovascularization is mentioned as a complication in the recurrent stage, and sunset-glow fundus is a sign of the convalescent or chronic stage after retinal reattachment.
Question 3: Oral and genital aphthae are rarely associated with Behçet's disease.
A. Ano
B. Ne
Explanation: Behçet's disease is characterized by oral aphthae and genital aphthae. These are key systemic manifestations used in diagnosis.
Question 4: What is indicated by a positive Pathergy test in the context of diagnosing Behçet's disease?
A. A normal immune response to a mild irritant
B. The immune system overreacting to a mild irritant
C. The presence of HLA-B27
D. An absence of any immune system reaction
Explanation: The study materials state that the Pathergy test is exclusive for Behçet's disease, and a positive test (red nodule after inserting a needle) indicates the immune system overreacting to a mild irritant.
Question 5: The management of Serpiginous Choroiditis primarily involves only systemic steroids, as other immunomodulators are not effective.
A. Ano
B. Ne
Explanation: The study materials indicate that while systemic steroids are used, the management of Serpiginous Choroiditis also includes other immunomodulators like Cyclosporine (in monotherapy), Azathioprine, and Cyclophosphamide, often in aggressive early treatment or triple therapy, to avoid progression and recurrence.
