Rip: part of wet Age Related Macular Degeneration (ARMD)
As part of wet ARMD Sometimes the retina in the macula area can tear and shrink. This is call a 'rip' or a 'tear' of the pigment epithelium. It may occur spontaneously as part of wet ARMD, but can occur after PDT or anti-VEGF treatment. A rip causes significant loss of central vision.
The chances of rip depend on how elevated the PED is (the retinal pigment epithelial detachment). For instance, an 840μ elevation has a 50% chance of ripping. A 500μ elevation has a 10% chance of ripping. Gelsiken 2009 Generally anti-VEGF reatment is still helpful .

Days. after the injection the sight improved, but then one week later the central vision disappeared (with lots of flashes of light like fire works)
