Question 1: Identify the Topographic Pattern [Figure 1]. Is it Normal?
Small central asymmetric bow-tie appearance in topography. It is indicative of keratoconus in spite thinnest patchy of 530 mic which is within normal limits.
Question 2: Rajeev C/o Blurred Vision of 2 weeks. He Gives a History of Taking a Nasal Spray for the Past 6 months. What Is the Diagnosis [Figure 2]? Name Any 3 Drugs (Other Than Steroids) That Are Reported to Cause This Condition.
Central serous chorioretinopathy. Pseudoephedrine and oxymetazoline (nasal sprays), ephedra (contained in body-building dietary products), sildenafil, tadalafil, vardenafil, binimetinib used for metastatic cancer.
Question 3: What Is the Diagnosis [Figure 3]? What Is the Associated Condition to Be Ruled Out?
Bear-track lesions of congenital hypertrophy of the retinal pigment epithelium. A subgroup of these lesions has been associated with familial adenomatous polyposis (Gardner syndrome).
Question 4: What Is This?
Wyburn–Mason Syndrome. The typical lesion consists of markedly dilated and tortuous vessels that shunt blood flow directly from arteries to veins [Figure 4]a.
In Fundus fluorescein angiogram (FA), these vessels do not leak fluid [Figure 4]b.
