Posterior vitreous detachment (PVD) is a condition of the eye in which the vitreous separates from the retina.[3][4] Symptoms include floaters and flashes of light in the peripheral vision.[1] Pain does not occur.[3] This generally resolves over a few months.[1] Complications may include retinal tear, retinal detachment, macular hole, macular pucker, and vitreous bleed.[1][2]
Risk factors include being nearsighted.[1] Episodes may be triggered by cataract surgery, trauma, uveitis, and laser capsulotomy.[2] The underlying mechanism involves age related softening of the vitreous.[3] Diagnosis is by dilated eye exam.[1] Other measures used may include ultrasound and optical coherence tomography.[2]
In most cases no specific treatment is required.[1] Follow up may be recommended in 2 to 4 weeks to rule out complications.[2] Outcomes are usually good.[2] If the condition causes significant problems surgery, known as a vitrectomy, may be tried.[1]
Posterior vitreous detachment becomes common as people age.[1] About half of people over the age of 50 are affected.[2] Women are more commonly affected at a younger age.[2] It was first described in 1856 by Muller and 1875 by Briere.[2]
