School Eye Health Programs Indian Medical PG Practice Questions and MCQs
Question 1: 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 2: In Ayushman Bharat under School Health Services, which of the following is not included?
- A. Health check-up/screening
- B. Albendazole provision
- C. Monthly Iron Folic Acid Supplementation
- D. Providing free spectacles (Correct Answer)
Explanation: ***Providing free spectacles*** - Under Ayushman Bharat School Health Services and RBSK (Rashtriya Bal Swasthya Karyakram), while **vision screening** is universally implemented, the provision of **free spectacles** is not uniformly guaranteed across all states and depends on fund availability and state-level implementation. - The primary focus remains on **screening and referral**, with spectacle provision being supplementary rather than a core mandated service compared to the other interventions listed. - Unlike the other three services which are universally delivered, free spectacles provision shows **geographic and implementation variability**. *Health check-up/screening* - **Comprehensive health check-ups** and screenings are a mandatory core component of the Ayushman Bharat School Health Program implemented uniformly across all states. - This includes screening for common conditions like **vision problems**, **hearing impairments**, **dental issues**, and growth monitoring. *Albendazole provision* - The administration of **Albendazole** for biannual deworming is a standard, universally implemented practice under the National Deworming Day initiative integrated with School Health Programs. - This is part of a broader strategy to improve the **nutritional status** and overall health of school-going children. *Monthly Iron Folic Acid Supplementation* - **Iron Folic Acid (IFA) supplementation** through the Weekly Iron Folic Acid Supplementation (WIFS) program is a key mandated intervention to combat **anemia** among adolescents (10-19 years). - This is universally implemented through School Health Services and directly contributes to improving **cognitive function** and physical health of students.
Question 3: 'S-A-F-E program' was initiated for the control of which of the following conditions?
- A. Ocular trauma
- B. Onchocerciasis
- C. Refractive error
- D. Trachoma (Correct Answer)
Explanation: ***Trachoma*** - The **S-A-F-E program** is a comprehensive strategy developed by the World Health Organization (WHO) for the elimination of blinding **trachoma**. - **S-A-F-E** stands for **Surgery** for trichiasis, **Antibiotics** for infection, **Facial cleanliness**, and **Environmental improvement**. *Ocular trauma* - While ocular trauma is a significant cause of vision impairment, its control and prevention strategies are distinct from the specific interventions of the SAFE program. - Management of ocular trauma focuses on immediate medical attention, surgical repair, and preventive measures like protective eyewear. *Onchocerciasis* - **Onchocerciasis**, also known as river blindness, is controlled primarily through mass drug administration of **ivermectin**, alongside vector control. - This condition is caused by a parasitic worm (**Onchocerca volvulus**) and is not targeted by the SAFE program. *Refractive error* - **Refractive errors** (e.g., myopia, hyperopia, astigmatism) are corrected with spectacles, contact lenses, or refractive surgery. - They are not infectious diseases and do not require the public health interventions outlined in the SAFE program.
Question 4: Which of the following procedures is not typically covered by the National Programme for Control of Blindness (NPCB) for reimbursement of surgery done by a non-governmental organization (NGO) eye hospital?
- A. Cataract surgery
- B. Pan retinal photocoagulation for diabetic retinopathy
- C. Syringing and probing of the nasolacrimal duct (Correct Answer)
- D. Trabeculectomy surgery
Explanation: ***Syringing and probing of the nasolacrimal duct*** - While important for lacrimal drainage issues, procedures like **syringing and probing** are generally considered minor and less vision-restoring compared to the major surgeries targeted by the **NPCB**. - The **NPCB** focuses on interventions for leading causes of blindness, primarily **cataract** and other significant vision-threatening conditions, which this procedure typically isn't. *Cataract surgery* - **Cataract surgery** is a cornerstone of the **NPCB's** efforts, as cataracts are the leading cause of reversible blindness. - Reimbursement for **cataract surgery** is a primary objective to improve access and reduce the burden of blindness. *Pan retinal photocoagulation for diabetic retinopathy* - **Diabetic retinopathy** is a major cause of preventable blindness, and **pan retinal photocoagulation (PRP)** is a key intervention to preserve vision. - The **NPCB** includes procedures for **diabetic retinopathy** management due to its significant public health impact. *Trabeculectomy surgery* - **Trabeculectomy** is a surgical procedure for **glaucoma**, which is another significant cause of irreversible blindness. - The **NPCB** includes interventions for **glaucoma** given its severe vision-threatening nature and the need for surgical management in many cases.
Question 5: Constantly changing refractive error is seen in:
- A. Morgagnian cataract
- B. Intumescent cataract
- C. Traumatic cataract
- D. Diabetic cataract (Correct Answer)
Explanation: ***Diabetic cataract*** - Fluctuating blood glucose levels in diabetes can cause changes in the **osmolarity of the aqueous humor**, which in turn affects the hydration of the lens and its refractive power. - This leads to a **constantly changing refractive error**, where a person's prescription might change rapidly over short periods of time. *Morgagnian cataract* - This is a type of **hypermature cataract** where the cortex has liquefied, allowing the nucleus to sink within the capsular bag. - While vision is severely impaired, it doesn't typically present with a constantly changing refractive error, but rather a stable, significant vision loss. *Intumescent cataract* - An **intumescent cataract** is a mature or hypermature cataract where the lens has become significantly swollen due to water absorption. - This swelling causes the anterior capsule to stretch, but it results in a fixed and profound vision loss, not a fluctuating refractive error. *Traumatic cataract* - A **traumatic cataract** develops as a result of blunt or penetrating ocular injury, causing damage to the lens fibers. - While the specific type of refractive error can vary depending on the trauma, it typically presents as a stable visual impairment rather than a constantly changing refractive error.
Question 6: Maximum correction of myopia can be done by?
- A. Radial keratotomy
- B. LASIK (Correct Answer)
- C. Photorefractive keratectomy
- D. Orthokeratology
Explanation: ***LASIK*** - **LASIK (Laser-Assisted In Situ Keratomileusis)** allows for significant correction of high myopia by reshaping the cornea with an excimer laser. - It involves creating a **corneal flap** and then ablating tissue underneath, offering precise and stable vision correction for a wide range of refractive errors. - Among the given corneal refractive procedures, LASIK can correct myopia up to **-10 to -12 D**. *Radial keratotomy* - **Radial keratotomy (RK)** involves making radial incisions in the cornea to flatten it, primarily used for low to moderate myopia (up to -3 to -4 D). - It has a higher risk of **unpredictable outcomes**, induced astigmatism, and glare compared to modern laser procedures. *Photorefractive keratectomy* - **Photorefractive keratectomy (PRK)** involves direct ablation of the corneal surface without creating a flap, which is suitable for moderate myopia (up to -8 to -10 D). - While effective, PRK typically has a **longer recovery period** and more post-operative pain than LASIK. *Orthokeratology* - **Orthokeratology (Ortho-K)** uses specially designed rigid contact lenses worn overnight to temporarily reshape the cornea and correct myopia. - The effect is **temporary**, requiring continuous lens wear to maintain vision correction, and is generally limited to low to moderate myopia (up to -4 to -6 D).
Question 7: Esotropia is commonly seen in which type of refractive error?
- A. Myopia
- B. Hypermetropia (Correct Answer)
- C. Astigmatism
- D. Presbyopia
Explanation: ***Hypermetropia*** - **Esotropia**, or convergent strabismus, is commonly associated with **uncorrected hypermetropia**, especially in children. - The constant effort to **accommodate** to see clearly for hypermetropic individuals can lead to excessive convergence, causing the eye to turn inward. *Myopia* - Myopia, or **nearsightedness**, rarely causes esotropia. - In some cases, high myopia can be associated with **exotropia** (divergent strabismus) due to reduced accommodative effort. *Astigmatism* - **Astigmatism** causes blurry vision at all distances due to an irregularly shaped cornea or lens, but it is not directly linked to specific forms of strabismus like esotropia or exotropia. - While it can contribute to **amblyopia** if severe and uncorrected, it does not typically cause the eyes to turn inward. *Presbyopia* - **Presbyopia** is an age-related loss of the eye's ability to focus on nearby objects due to stiffening of the lens. - It affects accommodation but does not cause strabismus such as esotropia; it typically begins around age 40.
Question 8: One year old male child with cat's reflex and raised IOP. What is the most likely diagnosis?
- A. Toxocara canis
- B. Retinopathy of prematurity
- C. Retinoblastoma (Correct Answer)
- D. Toxoplasma gondii infection
Explanation: ***Retinoblastoma*** - A **cat's reflex (leukocoria)**, which is a white pupillary reflex, is the most common presenting sign of retinoblastoma in children. - **Raised intraocular pressure (IOP)** can occur in advanced retinoblastoma due to secondary glaucoma caused by tumor growth or neovascularization. *Toxocara canis* - Ocular **toxocariasis** can cause leukocoria and inflammation, but it's typically associated with **granuloma formation** and not usually primary elevated IOP. - This condition is caused by a **parasitic infection** from roundworms, often seen in children with exposure to contaminated soil or pets. *Retinopathy of prematurity* - Primarily affects **premature infants** exposed to high oxygen, leading to abnormal retinal vessel development. - While it can cause leukocoria in severe stages, it would be unusual for a **one-year-old** to present with this primary diagnosis especially with raised IOP. *Toxoplasma gondii infection* - Ocular **toxoplasmosis** typically presents with **chorioretinitis** and can cause inflammation, but **leukocoria** and **raised IOP** are not its primary or most characteristic features. - This is a parasitic infection, congenital or acquired, often presenting with **retinal scars**.
Question 9: What is the primary health concern addressed by the Rashtriya Bal Swasthya Karyakram (RBSK)?
- A. Adult chronic diseases
- B. Elderly health
- C. Non-communicable diseases in the youth
- D. Comprehensive healthcare for children from birth to 18 years (Correct Answer)
Explanation: **Comprehensive healthcare for children from birth to 18 years** - The **Rashtriya Bal Swasthya Karyakram (RBSK)** is a national program explicitly designed to provide comprehensive health screening and early intervention for 0-18 year-olds - Its focus is on detecting and managing the **4 D's**: Defects at birth, Deficiencies, Diseases, and Developmental delays - The program provides regular health check-ups, early detection of health conditions, referral for treatment, and promotes healthy development across this critical age group *Adult chronic diseases* - While public health initiatives address adult chronic diseases, they are not the primary focus of the **RBSK** program, which targets a younger demographic - Programs like the **National Programme for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases & Stroke (NPCDCS)** are more aligned with adult chronic disease management *Elderly health* - **RBSK** is specifically focused on the health of children and adolescents, not the elderly population - **National Programme for Healthcare of the Elderly (NPHCE)** is a dedicated initiative for elderly health *Non-communicable diseases in the youth* - While **RBSK** does address some non-communicable diseases (NCDs) through early detection and management, its scope is much broader, encompassing all 4 D's - RBSK aims for **holistic child health** rather than exclusively targeting NCDs in youth, which is a subset of its overall mandate
Question 10: A person is not able to count fingers from a distance of 6 meters. He shall be categorized into which type of blindness?
- A. Moderate visual impairment
- B. Severe visual impairment (Correct Answer)
- C. Near-total blindness
- D. Profound visual impairment
Explanation: ***Severe visual impairment*** - Severe visual impairment is defined as visual acuity **less than 6/60 to 3/60** (presenting visual acuity). - The key clinical threshold is the **inability to count fingers at 6 meters**, which corresponds to VA < 6/60. - This category represents a significant functional vision loss where the person can typically still count fingers at 3 meters but not at 6 meters. - According to **WHO ICD-10 classification**, this falls under **Category H1** (severe visual impairment). *Moderate visual impairment* - Moderate visual impairment is characterized by visual acuity of **less than 6/18 to 6/60**. - A person with moderate visual impairment would **still be able to count fingers at 6 meters**. - This does not match the clinical presentation described in the question. *Profound visual impairment* - Profound visual impairment (also called **Blindness Category 1**) is defined as visual acuity **less than 3/60 to 1/60**. - The key threshold here is the **inability to count fingers at 3 meters** (but can count at 1 meter). - This is more severe than what is described in the question, as the question only specifies inability at 6 meters. *Near-total blindness* - Near-total blindness (**Blindness Category 2**) refers to visual acuity **less than 1/60 to light perception only**. - This represents the ability to perceive hand movements close to the face or only light perception. - This is far more severe than the presentation described in the question.
