She has had difficulty reading for the past 6 months. She tried using multiple over-the-counter glasses with different strengths, but they have not helped. She has hypertension and type 2 diabetes mellitus. Current medications include insulin and enalapril. Her temperature is 37.1C 98.8F, pulse is 80min, and blood pressure is 12684 mm Hg. The pupils are round and react sluggishly to light. Visual acuity in the left eye is 660 and in the right eye counting fingers at 6 feet. Fundoscopy shows pallor of the optic disc bilaterally. The cup-to-disk ratio is 0.7 in the left eye and 0.9 in the right eye N 0.3. Which of the following is the most likely diagnosis?? A: Hypertensive retinopathy, B: Age-related macular degeneration, C: Diabetic retinopathy, D: Open-angle glaucoma, E: Optic neuritisn,  <response>: Based on the information provided in the question stem, the most relevant details are:- 64-year-old woman with difficulty reading for the past 6 months- Tried using over-the-counter reading glasses without improvement - Medical history of hypertension and type 2 diabetes mellitus- Sluggish pupillary reaction to light - Decreased visual acuity bilaterally- Pallor of the optic discs and increased cup-to-disc ratios bilaterallyThe decreased visual acuity, sluggish pupillary reaction, pallor of the optic discs, and increased cup-to-disc ratios point towards a diagnosis involving the optic nerve. The bilateral findings make optic neuritis unlikely. The increased cup-to-disc ratios, especially the significantly elevated ratio in the right eye, indicate optic nerve damage most consistent with glaucoma. Therefore, the history and exam findings are most suggestive of open-angle glaucoma.D: Open-angle glaucoma
