Cautions
- Endophthalmitis may occur following any intraocular surgical procedure or injection; monitor and advise any signs or symptoms of infection or inflammation without delay
- Permanent decline in visual acuity may occur following subretinal injection; monitor for visual disturbances
- Retinal abnormalities (eg, macular holes, foveal thinning, loss of foveal function, foveal dehiscence, retinal hemorrhage) may occur; monitor and manage retinal abnormalities appropriately; do not administer voretigene neparvovex-rzyl near the fovea
- During or following vitrectomy, retinal abnormalities (eg, retinal tears, epiretinal membrane, retinal detachment) may occur; monitor during and following injection to permit early treatment of these retinal abnormalities; advise patients to report any signs or symptoms of retinal tears and/or detachment without delay
- Increased intraocular pressure may occur
- Avoid air travel, travel to high elevation, or scuba diving until the air bubble formed following administration has completely dissipated from the eye; may take above 1 week or more following injection for the air bubble to dissipate; changes in altitude, while the air bubble is still present, can result in irreversible vision loss
- Subretinal injection of voretigene neparvovex-rzyl, especially vitrectomy surgery, is associated with an increased incidence of cataract development and/or progression
