If you have been diagnosed with glaucoma you will require a 3-12 monthly follow up, depending on the severity of disease, the IOP levels under treatment, and other risk factors. The more severe the disease, the more frequent the follow-up. On the other hand, once the disease is well under control and there are no signs of progression, follow-up at longer intervals may suffice.
The bottom line is that the recommended interval between consultations may vary, and should be determined by your ophthalmologist. Of note, glaucoma patients will need follow-up visits for the entire life.
After the initial diagnosis, you will have to get the visual field test repeated to get a good baseline and then repeated more frequently in case the disease is advanced or if your pressure is not under adequate control.
After initial diagnosis, all individuals with glaucoma should perform proper documentation of the optic disc appearance and visual function status. Visual field tests often need to be repeated to get a good and consistent baseline. These exams should then be repeated periodically, in order to compare them for changes along mid and long-term follow-up.
