Understanding the Possible Causes of Decreasing Myopia Over Time
Reduction in myopia degree Hello, five years ago, I had a prescription of over 700 diopters at an optical shop. Three years ago, my prescription was measured at over 600 diopters, and recently, an eye doctor measured it at over 500 diopters. I would like to ask the doctor about t...
Dr. Gao Pilin Reply:
Hello Mr. Gong: The most common reason is a change in the refractive power of the lens. It should not be related to ocular atrophy or the optic nerve of the retina. I recommend that you see an ophthalmologist for an examination.[Read More] Understanding the Possible Causes of Decreasing Myopia Over Time

I have several questions regarding vision? I have a few questions that have persisted for several years: 1. When I focus on a straight line with my right eye alone, it appears slightly distorted, with a subtle wavy sensation. The Amsler grid test seems fine. The images of macular...
Dr. Gao Pilin Reply:
Hello, Ant: 1. A slight waviness may not be indicative of macular degeneration. Sometimes, it could also be related to refractive issues. 2. It is possible that there is a refractive problem, causing the image projected near the blind spot to appear somewhat distorted. 3. This ma...[Read More] Common Eye Issues: Understanding Vision Distortions and Prescription Needs
Understanding Pseudomyopia: Causes, Symptoms, and Eye Health Concerns
Pseudomyopia Hello, I would like to ask if high degrees of pseudomyopia make it easier for myopia to increase? Sometimes the degree before dilation is 600 or 700, but after dilation, it does not exceed 550 (previously 350, then 450, and later over 500). Is an increase of 50 to 75...
Dr. Gao Pilin Reply:
Hello, Xin: It is possible for the prescription to suddenly increase by 50 to 75 diopters within six months during the senior year of high school, and sometimes it can increase by 100 diopters in a year. Rapid changes can occur during periods of growth. If the eyeball degenerates...[Read More] Understanding Pseudomyopia: Causes, Symptoms, and Eye Health Concerns

Understanding Visual Impairment: Key Questions and Insights on Eye Health
Visual impairment Hello, I saw the standards for visual impairment online, and there are two criteria for mild visual field loss: 1. For the central 24-degree program on the automated perimetry, an average defect greater than 25 dB (exclusive) is required. 2. For the central 30-d...
Dr. Gao Pilin Reply:
Hello, S: Currently, the central 30 degrees should be used as a reference for visual field defects, which are not easily noticeable without examination.
