INTRODUCTION TO RETINAL

DETACHMENT (RD)

1.Definitions and classifications

•Retinal breaks

•Retinal detachment

2.Anatomy

•Anatomical landmarks

•Variants of ora serrata

•Vitreous base

3.Examination techniques

•Fundus drawing

•Slitlamp biomicroscopy

Definition and classification

•Break - full-thickness defect in sensory retina

•Hole - caused by chronic retinal atrophy

•Tear - caused by dynamic vitreoretinal traction
