CHAPTER 8

VISUAL IMPAIRMENT

This chapter contains two parts:

    Part 8.1 —  Impairment of Visual Function

    Part 8.2 —  Other Ocular Impairment

INTRODUCTION

Part 8.1 is to be applied to assess:
    any condition, such as refractive error, that is actually affecting visual function; and
    any condition, such as glaucoma or cataracts, that in the normal course of its progression would be likely to affect visual function.

Part 8.2 is to be applied to assess such conditions of the eye and the surrounding structures as may lead to discomfort or inconvenience, such as conjunctivitis and conditions of the eyelid, without actually or usually affecting visual function.

PART 8.1: IMPAIRMENT OF VISUAL FUNCTION

Loss of function

Visual function is to be measured by reference to:
    corrected visual acuity (Table 8.1.1 or Table 8.1.3); and
    visual field defects (Figures 8a and 8b); and
    miscellaneous function (Table 8.1.2).

The following steps take into account the fact that normal vision is a binocular function.

Calculation of the impairment rating for loss of visual function

Follow the steps below to calculate the impairment rating due to accepted loss of visual function.

(Each step is elaborated in the following pages.)

STEP 1  If there is any accepted refractive error, determine the monocular assessment for each eye based on corrected visual acuity.                            Page 133
STEP 2  If there is any accepted condition causing a visual field defect, determine the monocular assessment for each eye affected by the accepted condition.   Page 133
STEP 3  Determine the monocular assessment for each eye from the Miscellaneous Visual Function Table (Table 8.1.2) as the result of any accepted condition.     Page 134
STEP 4  For each eye separately, combine the ratings obtained in Steps 1, 2, and 3 by applying Chapter 18 (Combined Values Chart).                              Page 134
STEP 5  Combine the two combined monocular impairment ratings obtained in Step 4 by applying Table 8.1.3.                                                       Page 135

Step 1: If there is any accepted refractive error, determine the monocular assessment for each eye based on corrected visual acuity.

All assessments of visual acuity are to be based on corrected visual acuity, that is, the visual acuity as measured when the veteran is wearing glasses or contact lenses correctly prescribed. No additional impairment rating is to be given for the need to wear corrective lenses.

A separate monocular assessment is to be determined for each eye.

If only one eye has a refractive error, or if only one
