Describe the medicolegal aspects of ocular injury and the assessment of visual disability.

Documentation and Certification

• Ocular injuries generate legal proceedings more often than almost any other ophthalmic condition — through workmen’s compensation, motor accident claims, criminal assault, insurance and medical negligence — so the record made at the first consultation may be examined years later in court
• What must BE recorded, and each is regularly omitted:
• The visual acuity of both eyes, measured and recorded at presentation, with and without correction and with a pinhole. It cannot be reconstructed later and is the single most important entry
• The history in the patient’S own words, in quotation marks, including the mechanism, the time and place, and whether eye protection was worn. A paraphrase can be challenged; the original account cannot be recovered
• A diagram of the injury with measurements, and photographs where possible
• The state of the fellow eye, and any pre-existing disease — amblyopia, refractive error, previous surgery — since apportioning disability depends on distinguishing new damage from old
• The treatment given, the advice given, and the follow-up arranged; and any refusal of treatment or failure to attend.
• Entries must be contemporaneous, legible, signed, dated and timed. Corrections are made by a single line through the error, initialled and dated — never by obliteration.

Assessment of Disability and Medicolegal Principles

• Visual disability in India is certified under the rights OF persons with disabilities act 2016, which replaced the 1995 Act and expanded the recognised conditions
• The categories — blindness: visual acuity less than 3/60 in the better eye with best correction, or a field of less than 10 degrees; and low vision: acuity less than 6/18 to 3/60, or a field of less than 40 degrees. India revised its definition of blindness from 6/60 to 3/60 in 2017 to align with the WHO.
• Certification requires best-corrected acuity in each eye, the visual field, and the calculated percentage of disability from the prescribed tables, which weight both eyes and field loss as well as acuity
• Assessment should be deferred until the condition is stable — at least 6 to 12 months after injury, when recovery has plateaued and any cataract or scarring has been treated
• Distinguish impairment from disability and handicap — the measured loss of function, the resulting restriction of activity, and the social disadvantage that follows. A labourer and a clerk with identical acuity are differently disabled
• Principles the doctor should observe:
