  • Bilateral condition that involves retina peripherally between ora serrata and equator
  • Associated with hyperpigmentation, condensed overlying vitreous forming adhesions to margins of lattice degeneration that may cause subsequent retinal detachment
  • Fundoscopy: circumferential area of involvement with small criss-crossing white lattice lines (thickened hyalinized blood vessels)
Microscopic (histologic) description
  • Atrophic and thinned retina with superficial gliosis
  • Thickened and hyalinized retinal vessels
  • Overlying liquefaction of vitreous with vitroretinal adhesions at edge of lattice lesion
