Show Answer

Correct Answer � B

Explanation

  • The image shows degenerative changes in Pathological/degenerative myopia.
  • Pathological/Degenerative/Progressive myopia usually leads to degenerative changes in the retina along with a high degree of refractive error.
  • Degenerative myopia:

    • Refractive error may increase up to 20-25D with degenerative changes in the eye.
    • Temporal myopic crescent is a feature of pathological/degenerative myopia.
    • It is a white crescent at the temporal border of the disc.
    Some of the most typical features of degenerative myopia are:
    • Vitreous liquefaction and posterior vitreous detachment
    • Peripapillary atrophy appearing as temporal choroidal or scleral crescents or rings around the optic disc
    • Lattice degeneration in the peripheral retina
    • Tilting or malinsertion of the optic disc, usually associated with myopic conus
    • Thinning of the retinal pigment epithelium with resulting atrophic appearance of the fundus
    • Ectasia of the sclera posteriorly (posterior staphyloma)
    • Breaks in Bruch’s membrane and choriocapillaris, resulting in lines across the fundus called “lacquer cracks”
    • Foster Fuch’s spot in the macular area.
