Intravitreal injection (IVI) with administration of various
pharmacological agents is a mainstay of treatment in ophthalmology for
endopthalmitis, viral retinitis, age-related macular degeneration, cystoid
macular edema, diabetic retinopathy, uveitis, vascular occlusions, and retinal
The advantage of the IVI technique is the ability to maximize
intraocular levels of medications and to avoid the toxicities associated with
1 - Proliferative Diabetic Retinopathy.
2 - Age Related Macular Degeneration (AMD).
3 - Refractory Macular Edema.
Other conditions can benefit from IVI after careful discussion with your doctor.

Types & Popularity:
Since 2000 and 2005, the intravitreal applications of triamcinolone
acetonide and bevacizumab/ranibizumab have markedly increased in frequency as
therapy of diabetic macular oedema, exudative age-related macular degeneration
and other intraocular neovascular or oedematous diseases
Bevacizumab is commercially known as Avastin™, Rabibizumab is known as Lucentis™.
the list of reported complications includes infectious and noninfectious
endophthalmitis, secondary ocular hypertension potentially leading to secondary
steroid-induced open-angle glaucoma, and iatrogenic lesions to the intraocular
