Hi,
It sounds like you may be experiencing a condition called
diabetic retinopathy, which is a complication of
diabetes that affects the eyes. The retina is the part of the eye that senses light and sends visual signals to the brain. In diabetic retinopathy, high blood sugar levels can damage the blood vessels in the retina, leading to
vision loss.
One of the symptoms you described, difficulty seeing in darker areas, is known as "
night blindness." This can be caused by damage to the retina's light-sensitive cells (rods and cones) or the nerves connecting the retina to the brain.
Another symptom, difficulty seeing black or dark objects, is called "
color blindness." This can be caused by damage to the retina's cones responsible for sensing color. There is no cure for diabetic retinopathy, but early diagnosis and treatment can help slow or prevent vision loss. Your doctor may recommend a
laser treatment, which uses a laser to seal off leaking blood vessels in the retina.
In more advanced cases,
vitrectomy surgery may be necessary to remove blood from the eye and restore vision. You must continue to monitor your blood sugar levels and work with your doctor to manage your diabetes. This can help slow the progression of diabetic retinopathy and reduce your risk of vision loss. You'll need to speak with your doctor about this issue, and your doctor can give you more accurate information based on a complete examination.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Priyanka, General & Family Physician
