    SAFE strategy is recommended for control of:

    • A.

      Trachoma

    • B.

      Glaucoma

    • C.

      Diabetes mellitus

    • D.

      Cataract

    Correct Answer
    A. Trachoma
    Explanation
    The SAFE strategy is recommended for the control of trachoma. Trachoma is a bacterial infection of the eye that is caused by poor hygiene and is commonly found in areas with limited access to clean water and sanitation. The SAFE strategy stands for Surgery, Antibiotics, Facial cleanliness, and Environmental improvement. This approach involves providing surgical treatment for advanced cases, administering antibiotics to treat active infection, promoting facial cleanliness to reduce transmission, and improving environmental conditions to prevent reinfection. By implementing the SAFE strategy, the transmission and prevalence of trachoma can be reduced, leading to improved eye health in affected communities.

    The commonest cause of low vision in India is: [AIPG]

    • A.

      Uncorrected refractive erros

    • B.

      Cataract

    • C.

      Glaucoma

    • D.

      Squint

    Correct Answer
    A. Uncorrected refractive erros
    Explanation
    Uncorrected refractive errors are the most common cause of low vision in India. Refractive errors occur when the shape of the eye prevents light from focusing directly on the retina, resulting in blurred vision. This can include conditions such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. In India, many people do not have access to proper eye care or corrective lenses, leading to a high prevalence of uncorrected refractive errors. This highlights the importance of regular eye examinations and access to affordable eyeglasses or contact lenses to improve vision and prevent further deterioration.

      Myopia

    Correct Answer
    C. Cataract
    Explanation
    Cataract is the most common cause of blindness in India. A cataract is a clouding of the lens in the eye, which leads to a decrease in vision. It is usually caused by aging, but can also be caused by injury, certain medications, or medical conditions such as diabetes. Cataracts can be treated with surgery to remove the cloudy lens and replace it with an artificial one.

    For the field diagnosis of trachoma, the WHO recommends that follicular and intense       trachoma inflammation should be assessed in: [AIIMS]

    • A.

      Women aged 15-45 years

    • B.

      Population of 10 to 28 year range

    • C.

      Children aged 0-10 years

    • D.

      Population above 25 years of age irrespective of sex

    Correct Answer
    C. Children aged 0-10 years
    Explanation
    The WHO recommends that follicular and intense trachoma inflammation should be assessed in children aged 0-10 years. This age group is particularly vulnerable to trachoma infection and is more likely to develop severe complications if left untreated. By focusing on this age group, healthcare providers can identify and treat trachoma cases early, preventing further spread of the disease and reducing the burden of trachoma-related complications in the community. Assessing trachoma in other age groups may still be important, but the WHO specifically highlights the importance of screening children aged 0-10 years.

    In the school eye screening programme in India, the initial vision screening of school children is done by school teachers. This is because school teachers are often the first point of contact for students and are in a position to observe any visual problems or difficulties that the students may be experiencing. They can then refer the students to eye specialists or medical officers for further evaluation and treatment if necessary. Primary level health workers may also play a role in assisting with the screening process, but the primary responsibility lies with school teachers.

    • A.

      Cataract

    • B.

      Refractive error

    • C.

      Ocular injury

    • D.

      Vitamin-A deficiency

    Correct Answer
    B. Refractive error
    Explanation
    Refractive error is the most common cause of ocular morbidity in the community. Refractive error refers to the inability of the eye to properly focus light, resulting in blurred vision. This condition includes myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. Refractive errors can significantly impact a person's quality of life and can lead to various visual problems if left uncorrected. Cataract, ocular injury, and vitamin-A deficiency are also important causes of ocular morbidity, but refractive error is the most common among them.

      Economically blind

    • D.

      Normal vision

    Correct Answer
    C. Economically blind
    Explanation
    The correct answer is "Economically blind" because the patient's vision in both eyes is significantly impaired (6/60 in the right eye and 3/60 in the left eye). This classification is based on the National Programme for control of Blindness, which likely has specific criteria for determining different levels of visual impairment. The term "economically blind" suggests that the patient's visual impairment may have a significant impact on their ability to work and earn a living.

    WHO criteria for blindness is visual acuity of less than:

    • A.

      1/60

    • B.

      . 6/60

    • C.

      6/18

    • D.

      3/60

    Correct Answer
    D. 3/60
    Explanation
    The correct answer is 3/60. According to the WHO criteria for blindness, a person is considered blind if their visual acuity is less than 3/60. Visual acuity refers to the clarity or sharpness of vision, and a visual acuity of 3/60 means that a person can only see at 3 meters what a person with normal vision can see at 60 meters. Therefore, if someone has a visual acuity of less than 3/60, they are considered to have severe vision impairment or blindness.
