Question 1: Which of the following is NOT a core component of the WHO's global STI control strategy?
- A. Case management
- B. Universal mandatory screening (Correct Answer)
- C. Strategic information systems
- D. Prevention services
Explanation: ***Universal mandatory screening*** - While screening is part of STI control, **universal mandatory screening** for all STIs in the general population is not a core component of the WHO's strategy due to feasibility, cost, and ethical considerations. - The strategy emphasizes **targeted screening** for at-risk populations and opportunistic screening. *Case management* - **Case management**, including accurate diagnosis and effective treatment, is a critical component for managing current infections and preventing further transmission. - This involves syndromic or etiologic approaches to treatment and partner notification. *Strategic information systems* - **Strategic information systems** are essential for monitoring trends, evaluating interventions, and informing policy decisions related to STI control. - This includes surveillance data, program monitoring, and research. *Prevention services* - **Prevention services** are a cornerstone of the WHO's strategy, aiming to reduce the incidence of new infections. - These services encompass health education, condom promotion and distribution, vaccination, and pre-exposure prophylaxis (PrEP).
Question 2: All of the following conditions are immediate priorities in the WHO's "Vision -2020: The Right to sight" except:
- A. Cataract
- B. Epidemic conjunctivitis (Correct Answer)
- C. Onchocerciasis
- D. Trachoma
Explanation: ***Epidemic conjunctivitis*** - While **epidemic conjunctivitis** can cause significant discomfort and temporary vision impairment, it is generally **self-limiting** and rarely leads to permanent blindness. - It was not identified as one of the top five global causes of avoidable blindness targeted by the Vision 2020 initiative. *Cataract* - **Cataract** is the **leading cause of blindness** globally, accounting for approximately half of all cases. - It is a highly treatable condition through surgery, making it a critical priority for Vision 2020. *Onchocerciasis* - Also known as **river blindness**, onchocerciasis is a parasitic disease that causes severe visual impairment and blindness. - It is a significant public health problem in several regions, particularly in Africa, and was a key focus of Vision 2020 due to its widespread impact and the availability of preventive chemotherapy. *Trachoma* - **Trachoma** is the **leading infectious cause of blindness** worldwide, caused by *Chlamydia trachomatis*. - Given its preventable and treatable nature, and its prevalence in many impoverished areas, it was designated as one of the priority diseases under Vision 2020.
Question 3: Under NPCB, screening of school children is first done by -
- A. Ophthalmologic assistant
- B. Medical officer
- C. Village health guide
- D. School teachers (Correct Answer)
Explanation: ***School teachers*** - Under the **National Programme for Control of Blindness (NPCB)**, screening of school children follows a **three-tier approach**. - **School teachers** are trained to conduct the **first level/initial screening** using simple vision tests like **Snellen charts**. - They identify children with potential vision problems and refer them for further detailed assessment. - This approach maximizes coverage as teachers have regular contact with children and can screen large numbers efficiently. - The NPCB specifically includes **teacher training modules** for basic vision screening as part of the School Eye Screening Programme. *Ophthalmologic assistant* - Ophthalmic assistants/paramedical workers conduct the **second level screening** - the detailed assessment of children referred by teachers. - They perform comprehensive vision testing and identify specific refractive errors and eye conditions. - They are not the first point of contact in school screening due to resource limitations and the scale of screening required. *Medical officer* - Medical officers and ophthalmologists are involved in the **third tier** - providing diagnosis, treatment, and management of identified cases. - They handle complex cases, prescribe spectacles, and provide surgical interventions when needed. - They also supervise the overall program but do not conduct initial mass screening. *Village health guide* - Village health guides work primarily in community settings for general health promotion and basic healthcare. - While they contribute to community health awareness, they are not specifically involved in the structured school eye screening program under NPCB.
Question 4: Vision 2020 includes all of the following, except?
- A. Diabetic Retinopathy
- B. Refractive Errors
- C. Cataract
- D. Age-related Macular Degeneration (Correct Answer)
Explanation: ***Age-related Macular Degeneration*** - **Age-related macular degeneration (AMD)** was originally **not included** as one of the priority diseases in the initial "Vision 2020: The Right to Sight" initiative. - The initial focus was on conditions with a high burden of preventable blindness that were readily treatable or preventable with widely available interventions. *Diabetic Retinopathy* - **Diabetic retinopathy** is a major cause of preventable blindness and was specifically targeted by Vision 2020 efforts due to its increasing prevalence globally. - Early detection and treatment through retinal screening are crucial components of preventing vision loss from diabetic retinopathy. *Refractive Errors* - **Uncorrected refractive errors** are a leading cause of visual impairment worldwide, and their correction with spectacles is a simple and cost-effective intervention. - Vision 2020 emphasized accessible and affordable refractive error services to improve vision in affected populations. *Cataract* - **Cataract** is the leading cause of blindness globally, and its surgical removal is a highly effective and widely accessible treatment. - Vision 2020 prioritized increasing the number of cataract surgeries to restore sight to millions.
Question 5: All of the following are approaches to health education, except for which of the following?
- A. Service approach
- B. Regulatory approach
- C. Health education approach
- D. Clinical diagnosis approach (Correct Answer)
Explanation: ***Clinical diagnosis approach*** - The **clinical diagnosis approach** is used for identifying and treating diseases based on patient symptoms, signs, and diagnostic tests, not for health education. - While it's a critical aspect of healthcare, it doesn't represent a method for conveying health-related information to the public or patients for preventive or health-promoting purposes. *Service approach* - The **service approach** in health education focuses on providing health services and integrating health education directly into these services, such as during medical consultations or preventive health programs. - It uses the interaction between healthcare providers and patients as an opportunity to educate about health topics. *Regulatory approach* - The **regulatory approach** involves the use of laws, policies, and regulations to promote public health, often by influencing behavior or environmental factors. - Examples include regulations on smoking in public places or mandatory vaccinations, which implicitly educate the public about healthier choices or disease prevention. *Health education approach* - The **health education approach** is a direct and explicit method focused on empowering individuals and communities with knowledge and skills to make informed decisions about their health. - It involves planned activities and communication strategies designed to foster health literacy and positive health behaviors.
Question 6: Which of the following statements about conjunctival lesions is NOT true?
- A. Arise from any part of conjunctiva
- B. Can cause Astigmatism
- C. Surgery is treatment of choice (Correct Answer)
- D. UV exposure is risk factor
Explanation: ***Surgery is treatment of choice*** - While surgery can be used to treat conjunctival lesions, it is not always the **treatment of choice**, especially for smaller, asymptomatic lesions like **pinguecula** which may only require observation and lubrication. - Many conjunctival lesions, such as uncomplicated **pterygium** or **pinguecula**, are managed conservatively unless they cause significant symptoms, vision impairment, or cosmetic concerns. *Arise from any part of conjunctiva* - **Conjunctival lesions** can indeed arise from various parts of the conjunctiva, including the palpebral, bulbar, and forniceal conjunctiva. - For example, **pterygium** typically arises from the bulbar conjunctiva, while **pinguecula** also originates in the bulbar conjunctiva, specifically in the interpalpebral fissure. *Can cause Astigmatism* - Larger **conjunctival lesions**, particularly a **pterygium** that encroaches onto the cornea, can induce or alter astigmatism. - The growth of the lesion can change the **curvature of the cornea**, leading to optical distortion and astigmatism. *UV exposure is risk factor* - **Ultraviolet (UV) light exposure** is a well-established risk factor for the development of many conjunctival lesions, including **pterygium** and **pinguecula**. - Chronic UV exposure leads to **elastotic degeneration** of the conjunctival collagen and is thought to play a key role in the pathogenesis of these growths.
Question 7: Under the WHO "Vision 2020" program, the "SAFE" strategy is adopted for which of the following diseases:
- A. Glaucoma
- B. Onchocerciasis
- C. Trachoma (Correct Answer)
- D. Diabetic retinopathy
Explanation: ***Trachoma*** * The SAFE strategy is an acronym for **Surgery** for trichiasis, **Antibiotics** to treat infection (especially azithromycin), **Facial cleanliness**, and **Environmental improvement** to prevent transmission. * This comprehensive approach is central to the global elimination efforts for **trachoma**, as outlined by the WHO's Vision 2020 initiative. *Glaucoma* * Glaucoma management typically involves **medications (eye drops)** to lower intraocular pressure, laser therapy, or **surgery** to improve fluid drainage from the eye. * The SAFE strategy with its specific components (Surgery for trichiasis, Antibiotics, Facial cleanliness, Environmental improvement) is not applicable to the pathophysiology or treatment of **glaucoma**. *Onchocerciasis* * Onchocerciasis, or **river blindness**, is primarily controlled through mass drug administration of **ivermectin** to kill microfilariae and prevent new infections. * While both are Neglected Tropical Diseases causing blindness, the SAFE strategy is not designed for **onchocerciasis** prevention or treatment, which focuses on vector control and anthelmintic drugs. *Diabetic retinopathy* * Management of diabetic retinopathy focuses on **strict glycemic control**, managing blood pressure and lipids, and interventions such as **laser photocoagulation**, intravitreal injections of anti-VEGF agents, or vitrectomy for severe cases. * The term "SAFE strategy" with its specific interventions relates to bacterial infection control and environmental hygiene, which are not primary methods for managing **diabetic retinopathy**.
Question 8: Which of the following is a feature of mass media education?
- A. Easily understandable
- B. Deals with local problems of the community
- C. Wide approach
- D. Utilizes various media channels to reach a broad audience (Correct Answer)
Explanation: ***Utilizes various media channels to reach a broad audience*** - **Mass media education** by definition involves the use of channels like television, radio, internet, and print to disseminate information to a **large, heterogeneous audience**. - This broad reach allows for widespread public health campaigns and general informational programs, impacting a significant portion of the population simultaneously. *Deals with local problems of the community* - While mass media can address local issues incidentally, its primary characteristic is its **broad, rather than localized, reach**. - **Community-specific interventions** and grassroots efforts are typically more effective for directly targeting local problems. *Easily understandable* - The understandability of mass media content depends heavily on its **design and target audience**, and is not an inherent feature of the medium itself. - Complex health topics delivered through mass media may still be challenging for some segments of the population to fully grasp without further explanation. *Wide approach* - While "wide approach" can be interpreted as broad reach, the option "***Utilizes various media channels to reach a broad audience***" provides a more **specific and accurate description** of the mechanism behind this wide approach in mass media education. - The term "wide approach" is somewhat vague and does not explicitly define how that breadth is achieved, which is central to the concept of mass media.
Question 9: Vision 2020 "The right to sight" includes all except-
- A. Measles induced blindness (Correct Answer)
- B. Onchocerciasis
- C. Trachoma
- D. Cataract
Explanation: ***Measles induced blindness*** - Vision 2020 primarily targets conditions that are either preventable or treatable with *cost-effective interventions* and contribute significantly to *avoidable blindness*. - While measles can cause blindness, the specific program focuses on a defined list of priority diseases for intervention, and measles-related blindness is generally addressed through broader public health initiatives (vaccination) rather than direct "right to sight" surgical or direct medical interventions for established blindness. *Onchocerciasis* - **Onchocerciasis** (river blindness) is a major focus of Vision 2020 due to its profound impact on sight, particularly in endemic areas. - It is a **preventable** and **treatable** cause of blindness through mass drug administration. *Trachoma* - **Trachoma** is recognized as one of the leading infectious causes of blindness globally and is explicitly targeted by Vision 2020 through the **SAFE strategy** (Surgery, Antibiotics, Facial cleanliness, Environmental improvement). - It is a highly **preventable** and **treatable** condition, fitting the program's objectives. *Cataract* - **Cataract** is the leading cause of blindness worldwide and is highly **treatable** through a relatively simple and cost-effective surgical procedure. - Providing cataract surgery is a cornerstone of the Vision 2020 initiative to restore sight.
Question 10: The golden period of eye donation is
- A. 24 hours
- B. 12 hours
- C. 18 hours
- D. 6 hours (Correct Answer)
Explanation: ***6 hours*** - The **golden period** for eye donation, specifically for the removal of the **cornea**, is ideally within **6 hours** of death. - This timeframe is critical to ensure the **viability and quality** of the corneal tissue for successful transplantation, as cellular degradation begins rapidly after cessation of circulation. *24 hours* - While some tissues can be recovered up to 24 hours post-mortem, the **cornea's viability** for transplantation significantly decreases after the initial 6-hour window. - Beyond 6 hours, the risk of **cellular damage** and reduced graft success rate increases considerably. *12 hours* - A 12-hour window is generally considered too long for optimal **corneal tissue viability**. - While tissue might still be recoverable, the **quality and success rate** of the transplant are significantly lower compared to donation within 6 hours. *18 hours* - An 18-hour period is far beyond the recommended timeframe for **corneal donation**. - At this point, the **cellular integrity** of the cornea is highly compromised, making it unsuitable for transplantation.
