Q: I have been suffering from low vision and dryness of the optic nerve for the last 24 years. My doctor said there is no treatment available. Is there anything I can do?

A: Depending on what type of optic nerve disease you have, there may be treatment available. It would be difficult for me to outline the treatments available for your optic nerve disease without knowing the specific type of condition you have. Optic nerve disease encompasses a broad range of conditions.

You may also suffer from dry eyes, which is an ocular surface condition, unrelated to the optic nerve condition. Dryness of the eyes is alleviated by using lubricating eye drops that can be purchased over the counter at any drugstore.

Because of the damage to the optic nerve, you are most likely experiencing “low sight” due to reduced contrast sensitivity associated with optic nerve diseases. Therefore, you notice reduced vision in many lighting conditions including daylight which requires that you wear tinted filters indoors and outdoors to protect your eyes from glare problems that you may be experiencing.

It is recommended that you have a dilated eye examination by an optometrist or ophthalmologist in order to determine which optic nerve disease you have and determine which treatment is most appropriate for your condition. – Linda Pang, O.D. at Lighthouse International

Q: I was told I have bilateral iritis. What is it and how did I cause it? How can I prevent this from happening again?

A: Bilateral iritis means that there is inflammation affecting the colored portion of your eye, the iris. Bilateral iritis is likely to be associated with a systemic condition. If there is presence of an inflammation affecting other parts of your body, then it can also present with inflammation in the eyes. Therefore it is important that lab tests are performed to determine if there is an underlying cause. If the underlying cause can be determined (some cases of iritis have an unknown cause), proper treatment will be established to resolve the condition. Continue with the eye examinations by your optometrist or ophthalmologist. – Linda Pang, O.D. at Lighthouse International

Q: What is pseudophakia and also what is subluxation of the PCIOL?

A: Pseudophakia means having an artificial intraocular lens, which replaces the natural human lens. Pseudophakia is the result of cataract surgery. Subluxation of the posterior chamber intraocular lens (PCIOL) can be a complication of cataract surgery. Subluxation means the displacement of a structure. In this case, it is the misalignment of the posterior-chamber intraocular lens. Subluxation is a rare disorder that can occur after ocular injury/trauma or in systemic conditions such as Ehlers-Danlos syndrome, Marfan syndrome, and homocystinuria. – Linda Pang, O.D. at Lighthouse International
