April 2017

Barbara from Sacramento, United States of America, asks:
Double vision since rhw day after cataract surgery. Little improvement with prisms in eyeglasses. It is intermittent with or without glasses. If nerve damage, will there be hope of reversal of double vision?

Brian replies:
Dear Barbara, thank you for your email. When you experience binocular double vision, this is usually due to misalignment of your ocular muscles. This misalignment can occur due to a problem with the ocular muscles themselves or a problem with the nerves that supply these muscles. Monocular double vision, on the other hand, is likely to be due to an ocular problem such as cataract or posterior capsular opacification.

The fact that your double vision is intermittent suggests that it is binocular in nature. It is difficult to comment on whether the double vision will reverse without actually examining your eyes. As treatment may involve either prisms alone or surgery or a combination of both, it is definitely worthwhile for you to consult with an ophthalmologist who has a special interest in ocular motility disorders.

Good luck!

January 2017

Russell from Brea, United States of America, asks:
I went to the eye doctor last week and I have 20/400 in the right eye. Does that mean I am considered legally blind? My other eye is 20/25.

Brian replies:
Dear Russell, thank you for your query. Your right eye certainly has poor vision. However, to qualify as being legally blind, both eyes must have poor vision. Because your left eye is still seeing very well, you are therefore not considered to be legally blind.

December 2016

Joe from Orland Park, United States of America, asks:
On March 15th 2015 I had surgery for a detached retina which was successful. However, I have been having problems with my cornea. On June 9th 2016, I had a cornea transplant and the procedure was successful. However, I have about 20% cloudy vision and I keep getting abrasions. Doctor says my eye is just not healing properly. Doctor says that this usually happens to patients with diabetes and I do not have diabetes. Why is the eye not healing? Also I might add that through this whole ordeal I have never had any pain.


Brian replies:
Dear Joe, thank you for your query. I am sorry to hear about the problems you have had to face with both the retinal detachment and the cornea transplant.

Unfortunately, without examining your eyes, I am not able to tell you why your eye is not healing. What I will say though is that your eye has undergone two major surgical procedures, and so will take time to settle. From your description, it sounds as though your corneal epithelium is not healing properly, although corneal abrasions are normally accompanied by pain.

One suggestion that I have is to take Vitamin C as it can aid in the healing process for the corneal epithelium.

Good luck!

October 2016

Allen from St George, United States of America, asks:
My wife, Barbara, has: - map-dot-fingerprint corneal dystrophy of both eyes
- posterior vitreous detachment of both eyes
- combined forms of age-related cataract of both eyes
- pseudophakia of both eyes
- posterior capsular opacification (PCO) in right eye

She had cataract surgery on April 28th and May 10th, 2016. Today's date is October 18th, and her vision is more problematic than before surgery. Her corneal map-dot-fingerprint dystrophy disease is worse since. The corneal eruptions are sloughing off and causing the usual scratchiness and discomfort. One or both eyes cloud-up and she has intermittent pain in one or both eyes.

We are using Refresh Advanced, 5% Sodium Chloride Solution and Ophthalmic 5% SCS ointment. Her vision is inconsistent, both for far and near. It seams the map-dot-fingerprint dystrophy disease is worse after cataract surgery, though the Corneal Specialist said that the surgery would have no affect on it.

We do not know what to do!

Brian replies:
Dear Allen, thank you for your question. I am truly sorry to hear of your wife's predicament. Recurrent corneal erosion syndrome from corneal map-dot-fingerprint dystrophy (also known as corneal epithelial basement membrane dystrophy) can be difficult to manage. Barbara is already on the correct lubricant and hyperosmotic eye medications.

It may be worthwhile taking oral Vitamin C as well as the oral antibiotics, minocycline or doxycycline, as they may have a stabilizing effect on the corneal epithelium. Phototherapeutic keratectomy (PTK) may be a good option, because this laser technique removes the areas where the epithelium and basement membrane are worst affected, which then allows healthy re-epithelialization of the cornea to occur.

Good luck, and I hope Barbara's eyes settle soon.

September 2016

Supriya from Kolkata, India, asks:
My right eye is counting fingers at 1 metre and less than N36. May I get any certification?

Brian replies:
Dear Supriya, thank you for your question. The answer to your question depends on whether both of your eyes are visually impaired or only your right eye. If only your right eye has poor vision, then you are not considered to be partially sighted. On the other hand, if your right eye is your better eye and only sees counting fingers, then you are almost certainly eligible to be certified as a blind person.

I hope this helps answer your query.

March 2015

Joann from Nashville, United States of America, asks:
I have uveitis (6 years) and take Lisinopril. I had a bad reaction and want to know if you know of a blood pressure medication I can take. I will be on these long term as my family all have essential hypertension. I have problems urinating, pains in my stomach and blood pressure usually 120/80 with the above medication. Now I have weakness, tingling in hands, tiredness, heaviness in legs and pale stools, all side effects of Lisinopril with Ketorolac. I also use Pred Forte eye drops as well as steroid injections into eyes as needed. Blood pressure off the chart now. Any suggestions would be greatly appreciated, on what blood pressure medication I should be on.

Brian replies:
Dear Joann, thank you for your question. Ketorolac is known to reduce the anti-hypertensive effect of lisinopril, which is an ACE-inhibitor. To control your essential hypertension, you may need another class of anti-hypertensive medication, of which there are several. These include diuretics, alpha-blockers, beta-blockers, calcium channel blockers, and angiotensin II receptor antagonists. Your family doctor should be able to advise on the appropriate blood pressure medications for you to be on based on your medical history.

Another possible side effect that you must watch out for when receiving steroid as part of your uveitis treatment, is elevated intraocular pressure resulting in glaucoma. It is therefore important that your eye pressures are measured on a regular basis.

January 2015

Jo from Birmingham, United States of America, asks:
Shortly before moving to Alabama I lived in Georgia. The MD there said I should have a keratectomy prior to having cataract surgery. Now, here in Alabama the MD here is saying just the opposite. Cataract surgery first then the keratectomy. Please which should be first?

Brian replies:
Dear Jo, thank you for your question. With the current advances in laser refractive surgery, such as wavefront technology for photorefractive keratectomy and laser-assisted in situ keratomileusis, my opinion is that you should undergo cataract surgery first. Good luck!
