 prevention: "Refer to a specialized ophthalmologist for closer monitoring. Lifestyle modifications must be strictly adhered to, optimizing diabetes management to slow further vascular deterioration.",

 prevention: "Immediate intervention is required. Patients are at a very high risk of vision loss. Heavy restriction on strenuous activities may be advised to prevent spontaneous hemorrhaging.",
