Definition / general
- 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
