Which statement about 8-ball hyphema is true?

• A. It is Grade 2 hyphema
• B. It is Grade 4 hyphema
• C. It is Grade 3 hyphema
• D. It is Grade 1 hyphema

Answer: (B)

Grading hyphema is based on how much of the anterior chamber is filled with blood. An 8-ball hyphema describes the entire chamber being filled with blood, appearing as a dark round ball and obscuring the usual structures. This is the most severe form, corresponding to Grade 4 hyphema. The other grades reflect progressively less blood: less than one-third for Grade 1, one-third to one-half for Grade 2, and more than half but not fully filling for Grade 3.
