Question

Mr. A., age 72, has been treated for chronic glaucoma for 6 years. He has lost some peripheral vision but does not feel seriously impaired. There is one incident in his history 2 years ago when he decided to discontinue his eye drops for a month because he was comfortable and there was no change in his vision. He developed some eye discomfort and blurred vision. Examination confirmed elevated intraocular pressure (IOP) but little additional permanent damage. Since then an increased strength of eye drops was ordered to control IOP. List three references

1. Describe the pathophysiologic change in chronic glaucoma.

2. Why is there decreased peripheral vision?

3. Explain the reason for eye discomfort and blurred vision with increased IOP.

Mr. A. consulted his doctor about a dark area in his field of vision. It developed suddenly, although he had noticed a few dark floaters recently. He has no pain or discomfort, but the dark area is increasing in size. A detached retina in the right eye is diagnosed.

4. Explain the cause of the: (1) floaters, and (2) dark area in the visual field.

5. Why is it essential to reattach the retina immediately?
