Case 72 Diagnosis

Degenerative myopia with subfoveal choroidal neovascular membrane

Differential Diagnosis

  • Presumed ocular histoplasmosis syndrome: these patients typically have peripapillary hyperpigmentation and spots of chorioretinal atrophy (“histo spots”) scattered through the retina
  • Age-related macular degeneration (AMD): these patients typically have other manifestations of AMD, such as drusen and pigmentary clumping
  • Angioid streaks: fluorescein angiography would reveal the presence of these late-staining streaks emanating from the optic nerve head region
  • Idiopathic choroidal neovascular membrane: this diagnosis, by definition, requires that no other cause be identified. In this patient the high myopia was felt to be sufficient cause for the formation of the choroidal neovascular membrane
