PERIPHERAL RETINAL DISEASES
Retinal breaks are full thickness defects of the neurosensorial retina. When significant vitreoretinal traction is present at the break site and a liquefied vitreous is present, a retinal detachment can occur.
Breaks can be caused by atrophy of the inner retinal layers, vitreoretinal traction or trauma. According to their configuration breaks can be divided in: horseshoe tears, giant tears, operculated holes, dialyses, and atrophic retinal holes.
Horseshoe tears, have a U configuration, with the convexity usually pointing to the optic disc. They are caused by vitreous traction, exerted on the flap (frequently the vitreous remains attached to the flap and traction persists). When tears exceed 90 degrees circumferentially they are called giant tears. Tears are most commonly found in the supero-temporal...
