Differential Diagnosis for Swollen Gum with Blurry Vision

• Single most likely diagnosis
  • Gingivitis or Periodontal Disease: This condition is likely causing the swollen gum. The blurry vision could be unrelated, but if connected, it might suggest an underlying condition such as diabetes that contributes to both gum disease and vision problems.
• Other Likely diagnoses
  • Diabetes Mellitus: High blood sugar levels can lead to swollen gums (periodontal disease) and also cause blurry vision due to the effect of sugar on the lens of the eye.
  • Hypertension: High blood pressure can lead to changes in vision (blurry vision) and may also contribute to gum disease, although the connection is less direct.
  • Vitamin Deficiencies (e.g., Vitamin C deficiency): Deficiencies can cause gum problems (like scurvy) and potentially affect vision, though the connection to blurry vision is less common.
• Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
  • Temporal Arteritis (Giant Cell Arteritis): This condition can cause vision problems, including blurry vision, and jaw claudication, which might be mistaken for gum swelling or pain. It's a medical emergency due to the risk of blindness.
  • Endocarditis: Although less common, endocarditis (infection of the heart valves) can cause a variety of symptoms including vision changes and potentially gum infections or swelling, especially if there's a history of heart disease.
• Rare diagnoses
  • Wegener's Granulomatosis (Granulomatosis with Polyangiitis): A rare autoimmune disorder that can affect various parts of the body, including the gums and eyes, leading to symptoms like swollen gums and vision problems.
  • Sarcoidosis: Another rare condition that can affect multiple systems in the body, potentially causing gum swelling and eye problems, including blurry vision.
