Which eye disease is characterized by a "curtain falling" sensation and sudden vision loss?

• A. Retinal detachment
• B. Glaucoma
• C. Macular degeneration
• D. Cataracts

Answer: (A)

Retinal detachment is characterized by a sudden sensation of a "curtain falling" across the visual field, along with sudden vision loss. This phenomenon occurs when the retina, a thin layer of tissue at the back of the eye, pulls away from its normal position. As the retina detaches, patients may experience symptoms such as flashes of light, floaters, and a progressive loss of vision, often described as a shadow or curtain obscuring part of their vision. This condition is an ocular emergency that requires immediate medical attention to preserve vision. The nature of the symptom— the distinct feeling of something blocking the vision— aligns closely with the experience of individuals who have a retinal detachment. In contrast, glaucoma typically presents with gradual vision loss and often begins with peripheral vision deterioration, which does not resemble the "curtain falling" sensation. Macular degeneration primarily affects central vision over time and does not present with sudden loss akin to a curtain falling. Cataracts result in blurred vision and a gradual increase in visual impairment due to clouding of the lens but lack the sudden onset of symptoms associated with retinal detachment. Hence, the characteristics of retinal detachment clearly align with the symptoms described in this question.
