Modern cataract surgery seems to have no influence on the progression of diabetic retinopathy. A visual improvement is achieved in the majority of patients with NPDR, but poorer visual outcome is observed in patients developing macular oedema.

ABSTRACT.Purpose: To evaluate treatment of macular oedema due to branch retinal vein occlusion (BRVO) with intravitreal triamcinolone acetonide. Methods: In a prospective case series, nine patients with macular oedema due to BRVO received an intravitreal injection of 4 mg triamcinolone acetonide. Examination included best-corrected visual acuity (BCVA) for distance and reading, intraocular pressure (IOP) measurement, fluorescein angiography and high resolution imaging by optical coherence tomography, preoperatively and at 1 week, 1 month, 3 and 6 months postoperatively. Results: Preoperative mean BCVAs were 1.3 ± 0.8 for distance vision, and 1.1 ± 0.3 for reading acuity, respectively. A significant improvement in reading acuity was observed until 1 month (0.7 ± 0.4, p = 0.02). No significant reduction in mean macular thickness was observed. Conclusions: Intravitreal injection of triamcinolone acetonide led to a significant improvement in mean VA in patients with macular oedema due to BRVO. However, the significant effect was not permanent and persisted for only 1 month.

ABSTRACT.Purpose: To evaluate treatment of macular oedema due to central retinal vein occlusion (CRVO) with intravitreal triamcinolone acetonide. Methods: In a prospective case series, 13 patients with macular oedema due to non-ischaemic CRVO received an intravitreal injection of 4 mg triamcinolone acetonide. Examination included assessment of best corrected visual acuity (BCVA) for distance and reading, measurement of intraocular pressure (IOP), fluorescein angiography and high resolution imaging by optical coherence tomography, preoperatively and 1 week, 1 month, 3, 6 and 9 months postoperatively. Results: Preoperative mean BCVA was 0.9 -0.4 for distance vision and 1.0 -0.3 for reading acuity, respectively. A significant improvement in distance VA (0.5 -0.3, p < 0.001) and reading acuity (0.7 -0.3, p = 0.03) was observed until 3 months and 6 months, respectively. Mean macular thickness was significantly reduced until 9 months postoperatively. Conclusion: Intravitreal injection of triamcinolone acetonide led to a significant improvement in mean VA in patients with macular oedema due to CRVO. However, the significant effect was not permanent and persisted for a maximum of 6 months.

RRD occurs in a small percentage of patients after PPV with or without gas tamponade for vitreous hemorrhage or tractional retinal detachment caused by proliferative diabetic retinopathy. Thorough postoperative follow-up is important to make early diagnosis and intervention possible.

The introduction of HAART had a major impact on the medical history of patients with HIV-related eye disease with improved survival time and decreased morbidity.
