    Study Notes

    Case 1: Patient Information

    • 42-year-old male patient, Black ethnicity, with controlled hypertension and pollen allergy
    • Main complaint: reduced near visual acuity (VA)
    • First-time eye test patient

    Unaided Visual Acuity (VA) Results

    • Right Eye (RE) unaided VA: 6/9
    • Left Eye (LE) unaided VA: 6/6
    • Near VA: RE N5, LE N5

    Refraction and Eye Exam Results

    • Right Eye (RE) refraction: -0.25/+0.25 x 100 (6/6)
    • Left Eye (LE) refraction: plano/-0.25 x 95 (6/6)
    • Near refraction: +0.50 Add (N8) for both RE and LE

    Additional Test Results

    • Intraocular Pressure (IOP): RE 18mmHg, LE 20mmHg (at 13:57)
    • Tear Break-Up Time (TBUT) test: RE and LE showed break-up after 5 seconds
