What is logmar chart?

A logMAR chart is a visual acuity chart used to measure a person's ability to see at various distances. It consists of rows of letters or symbols that decrease in size as you go down the chart. The letters or symbols are arranged in a way that allows for accurate and precise vision testing.

What are the types of logmar chart?

There are various types of logMAR charts available for different purposes. Some common types include: 1. Standard LogMAR Chart: This is the most commonly used logMAR chart that has rows of letters or symbols. 2. Tumbling E Chart: Instead of letters, this chart uses the letter 'E' rotated in different orientations. It is often used for children or people who cannot read letters. 3. Sloan Letter Chart: This chart uses a set of standard letters, specifically designed for visual acuity testing. 4. Landolt C Chart: This chart uses a ring-like symbol with a gap that can be presented in different orientations. It is commonly used in clinical settings.

Questions & answers

How do you calculate logMAR chart?

Since there are 5 letters per line, the total score for a line on the LogMAR chart represents a change of 0.1 log units. The formula used in calculating the score is: LogMAR VA = 0.1 + LogMAR value of the best line read – 0.02 X (number of optotypes read)

What is the difference between Snellen chart and logMAR chart?

In logMAR notation, lower scores correspond to better vision, and as acuity becomes worse, the value of the logMAR increases. For every line of logMAR change there is 0.1 Δ, and for each letter there is 0.02 Δ. In Snellen notation, 20/20 vision corresponds to logMAR = 0 and the MAR is equal to 1.0 arc minute.

How do you convert visual acuity?

For example, you tested your vision from 10 feet and read the line 5 on the Snellen chart, then your visual acuity is 10/40. To convert to 20/20-based, you divide 20 by the distance you read from and then multiply that to the second number of the line you read. In this example, you divide 20 by 10, which is 2.

How do you convert a logMAR chart to a Snellen chart?

If the patient cannot read the top letter of the logMAR chart, simply halve the viewing distance, carry out the measurement, and add 0.30 logMAR to the score.
