Intravitreal steroids in the management of macular oedema

Although approximately 80% of Type 1 diabetics (., insulin-dependent) have retinopathy after 15 years of disease, only about 25% have any retinopathy after 5 years. The prevalence of proliferative diabetic retinopathy (PDR) is less than 2% at five years and 25% by 15 years. For Type 2 diabetes (non-insulin-dependent), however, the onset date of diabetes is frequently not precisely known and thus more severe disease can be observed soon after diagnosis. Up to 3% of patients first diagnosed after age 30 (Type 2) can have clinically significant macular edema or high-risk PDR at the time of initial diagnosis of diabetes.

About 20% of patients with retinal vein occlusions develop abnormal blood vessels growing on the iris at the front of the eye or on the retina. These abnormal blood vessels can bleed or cause a marked pressure rise in the eye leading to further loss of vision. This can normally be prevented by laser treatment to the retina, which is most effective if applied before vision is lost. For this reason, patients with central retinal vein occlusions are normally checked every four to six weeks for six months but branch retinal vein occlusions can be checked less often as the risk is much less.

On refractive exam, best corrected visual acuity (BCVA) can range from 20/20 to 20/ Visual loss can partly be attributed to a hyperopic shift caused by the anterior displacement of the macular photoreceptors. Folk recorded that patients with CSCR can have minimal afferent pupillary defects and reduced critical flicker-fusion thresholds, both of which are the first to improve with resolution of the CSCR episode. [47] Ophthalmoscopy typically discloses a round or oval serous macular detachment without hemorrhage, with small, yellow sub-retinal deposits in the area of neurosensory detachment. [22] At times, the sub-retinal fluid may contain grey-white serofibrinous exudate. [48] A RPE detachment may be seen on OCT in up to 63% of eyes [49] and if it encircles the detachment, a “halo” may be seen around the detachment. [48] Macular RPE mottling can be found in cases of recurrent or chronic CSCR. Ophthalmoscopy may show a range from mono- or paucifocal RPE lesions with prominent elevation of the neurosensory retina by clear fluid - typical of cases of recent onset - to shallow detachments overlying large patches of irregularly depigmented RPE.

Triamcinolone acetonide as an intra-articular injectable has been used to treat a variety of musculoskeletal conditions. When applied as a topical ointment, applied to the skin, it is used to mitigate blistering from poison ivy , oak, and sumac, [ citation needed ] . When combined with Nystatin , it is used to treat skin infections with discomfort from fungus, though it should not be used on the eyes, mouth, or genital area. [5] It provides relatively immediate relief and is used before using oral prednisone . Oral and dental paste preparations are used for treating aphthous ulcers .
