Retinal Detachment
Diagnosis of Retinal Detachment
Indirect ophthalmoscopy with pupillary dilation Retinal detachment should be suspected in patients, particularly those at risk, who have any of the following: Sudden increase or change in floaters Photopsias Curtain or veil across the visual field Any sudden, unexplained loss of vision Vitreous hemorrhage that obscures the retina Indirect ophthalmoscopy shows the retinal detachment and can differentiate the subtypes of retinal detachment in nearly all cases. Direct funduscopy using a handheld ophthalmoscope can miss some retinal detachments, which may be peripheral. Peripheral fundus examination, using either indirect ophthalmoscopy with scleral depression, the slit lamp with the eye in extreme positions of gaze, or using a 3-mirror lens, should be done. If vitreous hemorrhage (which may be due to a retinal tear), cataract, corneal opacification, or traumatic injury obscures the retina, retinal detachment should be suspected and B-scan ultrasonography should be done.
