A patient presents with a retinal detachment and is being evaluated for appropriate treatment. Which of the following procedures is used to treat retinal detachment by indenting the wall of the eye?
Scleral buckling
Photorefractive keratectomy (PRK)
Vitrectomy
Intravitreal injection
The Correct Answer is A
Choice A Reason:
Scleral buckling is a surgical procedure used to treat retinal detachment by indenting the wall of the eye. This technique involves placing a silicone band (buckle) around the sclera (the white part of the eye) to push the wall of the eye against the detached retina. This helps to reattach the retina and prevent further detachment. Scleral buckling is effective in treating many types of retinal detachments and is a common procedure for this condition.
Choice B Reason:
Photorefractive keratectomy (PRK) is a type of refractive surgery used to correct vision problems such as myopia, hyperopia, and astigmatism. It involves reshaping the cornea using a laser but is not used to treat retinal detachment. PRK does not involve indenting the wall of the eye or addressing issues with the retina.
Choice C Reason:
Vitrectomy is a surgical procedure that involves removing the vitreous gel from the eye to treat various eye conditions, including retinal detachment. While vitrectomy can be used to treat retinal detachment, it does not involve indenting the wall of the eye. Instead, it allows the surgeon to access the retina and perform necessary repairs.
Choice D Reason:
Intravitreal injection involves injecting medication directly into the vitreous cavity of the eye. This procedure is used to treat conditions such as macular degeneration, diabetic retinopathy, and retinal vein occlusion. It is not used to treat retinal detachment by indenting the wall of the eye.

Correct Answer is A
Explanation
Choice A Reason:
A sedentary lifestyle is a significant risk factor for developing type 2 diabetes mellitus. Lack of physical activity can lead to obesity, which is a major contributor to insulin resistance. Regular physical activity helps to maintain a healthy weight, improve insulin sensitivity, and reduce the risk of developing type 2 diabetes.
Choice B Reason:
A triglyceride level of 100 mg/dL is within the normal range and is not considered a risk factor for type 2 diabetes. Elevated triglyceride levels (above 150 mg/dL) are associated with an increased risk of developing type 2 diabetes, but a level of 100 mg/dL does not indicate an increased risk.
Choice C Reason:
A recent viral infection is not a recognized risk factor for type 2 diabetes While certain viral infections can trigger autoimmune responses leading to type 1 diabetes, they are not linked to the development of type 2 diabetes, which is primarily influenced by lifestyle factors and genetics.
Choice D Reason:
A blood glucose level of 98 mg/dL is within the normal range for fasting blood glucose and does not indicate an increased risk for type 2 diabetes. Prediabetes is diagnosed when fasting blood glucose levels are between 100 and 125 mg/dL, and diabetes is diagnosed at levels of 126 mg/dL or higher. Therefore, a blood glucose level of 98 mg/dL is not a risk factor for type 2 diabetes.
Correct Answer is D
Explanation
Choice A Reason:
Shortness of breath is not typically associated with Meniere’s disease. This condition primarily affects the inner ear, leading to symptoms related to balance and hearing. Shortness of breath is more commonly linked to respiratory or cardiovascular issues.
Choice B Reason:
Chest pain is not a characteristic symptom of Meniere’s disease. Chest pain is usually related to cardiac or musculoskeletal problems. Meniere’s disease affects the inner ear and does not typically cause chest pain.
Choice C Reason:
Fever is not a common symptom of Meniere’s disease. Fever is generally associated with infections or inflammatory conditions. Meniere’s disease involves the buildup of fluid in the inner ear, leading to vertigo, tinnitus, and hearing loss, but not fever.
Choice D Reason:
Vertigo is the most characteristic symptom of Meniere’s disease. Vertigo involves a spinning sensation that can be severe and debilitating. It is caused by the abnormal fluid buildup in the inner ear, which disrupts the balance and hearing functions. This symptom is a hallmark of Meniere’s disease and is often accompanied by tinnitus and hearing loss.
