1).What is the most probable diagnosis?
      1. Diabetic Maculopathy
      2. Mature Senile Cataract
      3. Glaucoma
      4. Drug-Induced Visual Loss
      5. Retinitis Pigmentosa

 How to exclude others

● To exclude Diabetic Maculopathy: She is not a known diabetic; she denies
polyuria or polydipsia.
● To exclude Retinitis Pigmentosa: She denies “tunnel vision” and states her night
vision was perfectly fine until the general blurring started. No family history of
early-onset blindness.
● While cataracts can lead to secondary glaucoma, the patient has a “painless”
progression and a “normal depth” anterior chamber (noted in the case), which helps rule out acute or narrow-angle glaucoma secondary to a swollen
(intumescent) lens.
● To exclude Drug-Induced Cataract: No history of prolonged use of systemic
steroids for asthma or arthritis.
