This represents a visual acuity without glasses/contacts of 20/400 in the right eye, improving to 20/30 with pinhole testing; counting fingers at 8 ft in the left eye, improving to 20/40 with pinhole testing.
Pinhole testing is helpful in assessing the visual acuity of someone who has a refractive error but does not have corrective lenses available. The pinhole allows only parallel rays (collimated light) to fall on the macula, thereby reducing the refractive error and allowing an estimate of the person's corrected visual acuity.
This represents an intraocular pressure of 14 mmHg in the right eye and 15 mmHg in the left eye measured by Tonopen.
