Treatment of diabetic retinopathy neovascularisation is/are:
**Core Concept**
Diabetic retinopathy neovascularization is a complication of diabetes characterized by the growth of new, fragile blood vessels in the retina, leading to vision loss. This process is mediated by increased vascular endothelial growth factor (VEGF) and other angiogenic factors.
**Why the Correct Answer is Right**
The treatment of diabetic retinopathy neovascularization involves inhibiting VEGF and other angiogenic factors to prevent further growth of new blood vessels. Anti-VEGF therapies, such as ranibizumab and bevacizumab, are administered via intravitreal injections to reduce VEGF levels and slow disease progression. Additionally, laser photocoagulation and vitreoretinal surgery may be performed to treat complications such as vitreous hemorrhage and tractional retinal detachment.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because while steroids may be used to treat some ocular conditions, they are not the primary treatment for diabetic retinopathy neovascularization.
**Option B:** This option is incorrect because while laser photocoagulation is a treatment for diabetic retinopathy, it is not the primary treatment for neovascularization.
**Option C:** This option is incorrect because while vitreoretinal surgery may be performed to treat complications of diabetic retinopathy, it is not the primary treatment for neovascularization.
**Clinical Pearl / High-Yield Fact**
Anti-VEGF therapies have revolutionized the treatment of diabetic retinopathy neovascularization, significantly reducing the risk of vision loss in patients with this condition.
**Correct Answer: A. Anti-VEGF therapies, such as ranibizumab and bevacizumab, are administered via intravitreal injections to reduce VEGF levels and slow disease progression.**
