Investigations for Diabetic Retinopathy
If diabetic retinopathy is noted, color photographs of the retina may be taken and FLUORESCEIN ANGIOGRAPHY performed. This involves dilating the pupils and injection of a fluorescent dye into a vein in the arm. Photographs of the retina are taken rapidly as the dye passes through the retinal blood vessels. This test helps in determining if laser photocoagulation treatment is necessary. If treatment is to be done, it helps in identifying what structures and areas need treatment with laser.
OPTICAL COHERENCE TOMOGRAPHY (OCT), which is newer non-invasive diagnostic modality provides a cross-sectional view of the retina and helps in quantifying the amount and type of swelling and guides the treatment.
Common Side Effects in Diabetic Macular Edema
The most common side effects reported in patients with diabetic macular edema include: cataract, increased eye pressure, conjunctival blood spot, reduced vision, inflammation of the conjunctiva, specks that float in the field of vision, swelling of the conjunctiva, dry eye, vitreous detachment, vitreous opacities, retinal aneurysm, foreign body sensation, corneal erosion, inflammation of the cornea, anterior chamber inflammation, retinal tear, drooping eyelid, high blood pressure, and bronchitis.
