A patient's record shows a prescription of OD +2.50 OS NLP. In their left eye, the patient is _________.

• A. partially sighted
• B. mildly affected
• C. totally blind
• D. fully functioning

Answer: (C)

The notation presented in the patient's prescription indicates that the left eye (OS) has "NLP," which stands for "no light perception." This term is used to describe a complete absence of sight; that is, the patient is unable to perceive any light at all through that eye. The right eye (OD) has a prescription of +2.50, suggesting that it has some level of functioning vision, but since the question focuses on the condition of the left eye, the relevant information is the NLP designation. In ophthalmic terms, a patient with NLP in one eye is classified as totally blind in that eye. Therefore, describing the patient's left eye as totally blind is accurate given the circumstances. Other descriptions, such as partially sighted or mildly affected, do not apply in this scenario, as they imply some remaining vision, which is absent in the left eye.
