(B) Ans. b. Myopic degeneration can lead to retinal detachmentDegenerative myopia: ? It is seen in more than 6 dioptres of myopia.? More common in females as compared to males.? The condition has a racial predilection; it is more common in Jews and Japenese people, and most cases are of genetic origin.Patients with degenerative myopia typically complain of decreased vision, headaches, and sensitivity to light. If retinal degeneration or detachment is present, patients may also repo light flashes and floaters, which are associated with retina changes. Those with degenerative myopia have an increased incidence of cataract formation (nuclear cataracts are most typical).Some of the most typical features of degenerative myopia are:Vitreous liquefaction and posterior vitreous detachmentPeripapillary atrophy appearing as temporal choroidal or scleral crescents or rings around the optic discLattice degeneration in the peripheral retinaTilting or malinseion of the optic disc, usually associated with myopic conusThinning of the retinal pigment epithelium with resulting atrophic appearance of the fundusEctasia of the sclera posteriorly (posterior staphyloma)Breaks in Bruch's membrane and choriocapillaris, resulting in lines across the fundus called "lacquer cracks"Fuchs spot in the macular area.
