Glaucoma

Glaucoma: intraocular pressure↑ causes nerve damage (optic disk cupping, cup-disk ratio↑), visual field loss, can be open angle (chronic, pressure can escape) or closed angle (acute, pain, headache, see halos), tx w PGs, beta-blk

  • Glaucoma
  • intraocular pressure↑ causes nerve damage (optic disk cupping, cup-disk ratio↑), visual field loss, can be open angle (chronic, pressure can escape) or closed angle (acute, pain, headache, see halos), tx w PGs, beta-blk
  • open angle (gradual visual field loss), closed angle (pain, headache, see halos, rapid vision loss)
  • visual field loss, optic disk (cupping, cup-disk ratio > 0.5), Goniolens (open vs closed angle)
  • intraocular pressure↑
  • intraocular (aqueous humor) pressure↑, optic nerve dmg, closed angle (pressure can't escape, acute symptoms), open angle (chronic, pressure can escape)
  • lower intraocular pressure: prostaglandins (-prost), beta-blk, alpha agonist (-nidine), carbonic anhydrase inh, laser/surg. Blindness if untreated
