My name is Nathan, I am 40 years old. One and a half years ago I developed a rare retina disease called Central Serous Retinopathy.

The retina disease ultimately damaged the retina in my right eye, which led to binocular diplopia accompanied by unmanageable symptoms of severe tightness, pressure, pain, and discomfort in the ocular area and frontal head area.

I have tried countless forms of treatment, therapies and medication. The one, and only thing that has had a significant and real positive impact on my symptoms is the CarboHaler. I received my CarboHaler this past Friday, and only a few days in to using it I have already experienced a significant reduction in my symptoms. I personally use the device 2 to 3 times a day with the carbon dioxide levels set between 5 to 8%. My sessions usually last between five and 10 minutes.

I am very grateful for this device, and look forward to continued progress on my healing journey.

Hello. My name is Nathan. I am 40 years old. About a year and a half ago, I developed a rare retina disease that damaged the retina in my right. Because of this damage to my retina, I consistently experienced symptoms of severe head tightness and pressure, severe eye tightness and pressure, pain, discomfort mostly around my eyebrows, my eyes and my forehead. 

I've tried many different types of therapies and medications and treatments and found out about the CarboHaler. I received my CarboHaler last Friday. Today is Tuesday following so it's only been a few days that I've had the CarboHaler. I've been using it about two to three times a day and my symptoms have improved significantly. I've had a real drop in pain, discomfort, that tightness, that pressure feeling I mentioned. Nothing that I've tried up until this point has given me the relief that I have experienced through the CarboHaler. When I use it, I usually set it to between five and seven percentage of carbon dioxide and usually use it for about 5 to 10 minutes a session two or three times a day. Thanks for letting me share my story about my experience with the CarboHaler.
