Is there a link between kidney and vision problems.

The national kidney foundation has estimated the number of people struggling with chronic kidney disease to be 30 million. Kidneys are critical organs in the body that help expel the waste and toxicity from our bodies. 

The malfunction of kidneys may cause the balance of minerals in the body to get disturbed. It can also have an adverse effect on blood pressure, as kidneys are responsible for generating the hormones that regulate blood pressure. 

If kidney disease is not treated with proper medical attention, it may lead to weak bones, nerve damage, or anemia.

Below are the symptoms of kidney disease:

  • Lowering of energy levels
  • Issues with concentration and focus
  • Swelling in legs and feet due to fluid retention
  • Loss of appetite
  • Parched skin
  • Muscle cramps especially at night

Vision problems due to kidney disease:

One of the prevalent doubts among patients with kidney disease is ‘can kidney failure cause blindness’. Diabetes is often the reason for kidney disease and this considerably increases the risk of eye-related problems. If you don’t have diabetes and kidneys are failing to properly filter the waste, it can still lead to eye issues.

If the waste substances are not adequately removed by the kidneys, it may lead to a build-up of minerals and salts. These include phosphate and calcium. This accumulation of minerals may end up in the eyes and lead to dry and irritated eyes. Periorbital edema may also be the result of kidney disease. It is characterized by swelling around the eyes. This condition may impact one or both eyes.

The factors that cause chronic kidney disease may also negatively impact the eyes and vision. High blood pressure and diabetes are common examples of this. They cause chronic kidney disease and may also cause retinopathy. Retinopathy is a condition when the blood vessels in the retina are damaged. 

Different people experience different severity of retina damage. Sometimes, scar tissue is formed from the damaged vessels and may result in a detached retina. This happens in very serious cases and may lead to vision loss or blindness.

Are you also wondering, can kidney disease cause blindness? Yes, it can. It is thus very important to take care of your eye and kidney health. The section below will help you with more information.

How to keep your eyes healthy when you have kidney disease:

It is necessary to monitor your health if you are suffering from chronic kidney disease. You must also be cautious about your eyes and vision. Here are some recommended steps that you must follow:

  • Visit your ophthalmologist regularly:
Even if you are currently not experiencing any eye-related issues, visit an ophthalmologist regularly if you have kidney disease. This is because some eye diseases may not show early symptoms. 

Regular check-ups will mean that you will get a diagnosis before your eye condition worsens. After checking the condition, the doctor will advise you on how frequently you should get eye checkups.

  • Be aware of the signs of eye disease: 
Kidney disease increases the possibility of vision loss. Below are some indicative symptoms. If you observe any of them, it is in your best interest to visit the doctor immediately:
  1. You feel as if you can see flashing lights
  2. Vision changes suddenly causing hazy vision or no vision
  3. The sudden appearance of floaters in the eyes
  • Keep blood pressure and glucose levels in check: 
High blood pressure and diabetes often occur alongside each other. Chronic blood pressure may adversely affect your eyes and so can diabetes. Both your kidneys and eyes will benefit if you control blood pressure and sugar levels. A specialist will be able to guide you better about the ideal levels, frequency of monitoring, and the best ways to control the levels.
  • Follow the proper diet, workout, and medication routine: 
The appropriate treatment for kidney disease will depend on the severity and stage. The doctor will advise appropriate medication and lifestyle modifications to control the condition. In case the disease is too severe, dialysis may also be advised. 

Stick to the treatment plan as advised by the doctor and do not take it lightly. Do not ignore the dietary recommendations and workout advice. Keep the salt intake minimum and take all medicines prescribed. This will prevent further worsening of your eye and kidney issues.

  • Stay away from that cigarette: 
Both kidneys and vision get adversely affected by smoking. Smokers are at a greater risk of contracting glaucoma or cataract. Doctors advise kidney patients against smoking. If you are having a tough time quitting the smoking habit, ask for a recommendation on nicotine replacement products from your healthcare practitioner.

It is very important to take care of both your kidneys and vision. Kidneys can impact other organs of the body as well. Follow basic guidelines and take care of your health. Do not hesitate to visit a doctor and avoid your condition from worsening further.


Now that you know that kidney disease can cause blindness too, it is a good idea to go for that eye check-up following your doctor’s advice.
