In simple words: This code describes a complication of type 1 diabetes that affects the eyes. Because the body can't properly use sugar, the high sugar levels damage the small blood vessels at the back of the eye. The body then grows new blood vessels which are weak and prone to bleeding, leading to vision loss if untreated.

Type 1 diabetes mellitus with proliferative diabetic retinopathy (PDR) is a chronic autoimmune disease characterized by the destruction of pancreatic beta cells, resulting in insufficient insulin production. This leads to elevated blood glucose levels, damaging the retinal blood vessels and causing excessive growth of new, fragile vessels.These vessels can bleed into the vitreous humor, potentially causing blurred vision, floaters, macular edema, retinal detachment, and vision loss. General symptoms of Type 1 diabetes include fatigue, polydipsia, polyuria, polyphagia, and unintentional weight loss.

Example 1: A 25-year-old patient with a history of type 1 diabetes presents with blurred vision and floaters. Ophthalmologic examination reveals neovascularization and vitreous hemorrhage, confirming proliferative diabetic retinopathy., A 50-year-old with long-standing type 1 diabetes experiences sudden vision loss.Diagnosis reveals tractional retinal detachment secondary to proliferative diabetic retinopathy, requiring surgical intervention., A 30-year-old pregnant woman with type 1 diabetes undergoes regular eye exams to monitor for worsening retinopathy due to hormonal changes and increased risk during pregnancy.

Documentation should include detailed ophthalmologic findings, including the type and extent of retinopathy, presence of macular edema, vitreous hemorrhage, or retinal detachment.HbA1c levels, diabetes management history, and any other relevant medical conditions should also be documented.

** Regular eye exams are crucial for early detection and management of diabetic retinopathy in patients with type 1 diabetes.
