Purpose:
To evaluate the efficacy and safety of intravitreal triamcinolone in patients with macular oedema of varying aetiology.
Methods:
Two milligrams of intravitreal triamcinolone acetonide was injected into 34 eyes with persistent macular oedema (17 eyes with macula oedema secondary to posterior uveitis, 13 eyes with diabetic retinopathy, and four with pseudophakic macular oedema). Best corrected visual acuity was determined and transfoveal optical coherence tomography performed after 1 week, 1 month, 3 months and 6 months.
Results:
Treatment improved visual acuity and subjective visual quality, and reduced foveal thickness in eyes with posterior uveitis and eyes with macular oedema secondary to diabetic retinopathy. Eyes treated for pseudophakic cystoid macular oedema demonstrated no improvement. A total of 32% of patients experienced a significant post-injection increase in intraocular pressure. Endophthalmitis, rhegmatogenous retinal detachment and cataract were absent.
Conclusion:
Intravitreal triamcinolone appears to induce marked a improvement in macular oedema secondary to non-infectious uveitis and diabetic retinopathy.
