![]() ![]() A sudden change in, or loss of, vision occurs – or a dark shadow or curtain appears in your vision.Please contact an Ophthalmologist promptly if: As vitreoretinal surgical techniques have improved over recent years the risk associated with the surgery and the post-operative pain and discomfort has decreased dramatically. It is, therefore, now reasonable to consider vitrectomy surgery to remove floaters and vitreous debris if you are suffering persistent disturbance of your vision which interferes with normal activities such as reading. This usually results in complete resolution of symptoms. In these patients it is possible to remove the floaters via vitrectomy surgery. However, in some patients the floaters persist, obscuring central vision and causing intermittent difficulty with reading. In the majority of people the floaters fade over a few months and become less troublesome. In the majority, this damage does not adversely affect the vision, but some patients require long term treatment to keep the eye pressure controlled. If the high pressure is extreme or becomes prolonged, there may be some damage to the optic nerve as a consequence. In most cases it is short-lived and controlled with extra eye drops and/or tablets to reduce the pressure, preventing any harm coming to the eye. Raised eye pressure: an increase in pressure within the eye is quite common in the days after surgery, usually due to the gas bubble.Infection: this is also very rare and would be expected to occur in about 1 in 1000 patients, but if it occurs, can lead to visual loss. ![]()
