Precursors of retinal detachment

Precursors of retinal detachment mainly include the following: 1. Decreased vision: Patients may experience gradually declining vision, especially in the central visual field. 2. Visual field defects: Retinal detachment can cause defects in the visual field, commonly manifesting as blurriness in the central vision. 3. Photopsia (flashing lights): Prior to retinal detachment, patients may perceive flashes of light, which result from tears or separation in the retinal pigment epithelium. 4. Shadow or curtain over the visual field: As retinal detachment progresses, patients may notice a dark shadow or curtain obscuring part of their vision, further impairing eyesight. If any of the above symptoms occur, prompt medical attention is recommended for professional evaluation and treatment.
