It is a grid of straight horizontal and vertical lines with a central point, used as a tool to detect visual disturbances in patients with scotoma or other anomalies.
If a patient with age-related macular degeneration (AMD) sees wavy lines, should it be treated as an emergency?
Yes, it is an emergency, but relatively speaking, as it is possible to wait 3 or 4 days. It is necessary to examine the eye, because the symptom could indicate the onset of decompensation, which can cause severe loss of vision. This distortion is sometimes not due to decompensation, but it always needs to be confirmed.
Are there any new treatments for AMD?
Age-related macular degeneration is one of the greatest challenges in ophthalmology today. We know that there are two types: the dry form and the wet form. The dry form is experienced by patients who are slowly losing their vision. It has been demonstrated that treatment with antioxidants and vitamins can reduce vision loss, although the slowing down of the process is not particularly spectacular. The wet form, which is so called because fluid is produced in the macula, is the most destructive, and current treatment involves the combining of photodynamic therapy, which started to be used some years ago, with other treatments, which has produced more positive results. Each year, new possibilities appear, which help in the fight against this disease.
