Both macular telangiectasia and age-related macular degeneration (AMD) lead to photoreceptor atrophy and loss of central vision. The two diseases may be distinguished by symptoms, clinical features, and pathogenesis. The natural history of macular telangiectasia suggests a slowly progressive disorder.
Telangiectasia macularis eruptiva perstans (TMEP) is persistent, pigmented, asymptomatic eruption of macules usually less than 0.5 cm in diameter with a slightly reddish-brown tinge. [ 1 ] : 616 [ 2 ]
Posterior sub-Tenons steroid injections (PSTSI) is used in the treatment of posterior ocular inflammation, such as chronic uveitis. [2] This route is also reported to be used to administer triamcinolone acetonide (a corticosteroid) in the treatment of macular telangiectasia type 1. Also, it is used in the ocular anesthesia. [3]
Age-Related Macular Degeneration is a degenerative maculopathy associated with progressive sight loss. It is characterised by changes in pigmentation in the Retinal Pigment Epithelium, the appearance of drusen on the retina of the eye and choroidal neovascularization. AMD has two forms; 'dry' or atrophic/non-exudative AMD, and 'wet' or ...
Findings include delayed venous filling, hypofluorescence caused by hemorrhage and capillary nonperfusion, dilation and tortuosity of veins, leakage due to neovascularization and macular edema. Optical coherence tomography is an adjunctive test in branch retinal vein occlusion. Macular edema is commonly seen on optical coherence tomography exams.
The book, "Stereoscopic Atlas of Macular Diseases: Diagnosis and Treatment," describes several hundred congenital, infectious, age-related and inflammatory eye diseases. Illustrating those disorders with photographs and drawings, the work is widely known as Gass's Atlas and is now in its fourth edition.
Macular scarring is formation of the fibrous tissue in place of the normal retinal tissue on the macular area of the retina which provides the sharpest vision in the eyes. It is usually a result of an inflammatory or infectious process. [1] Other etiologies include macular pucker (macular detachment), macular hole, and age-related macular ...
Patient is asked to sit in front of an illuminated vision chart, at 6 meter distance. Initial measurement of best corrected visual acuity should be done. Locate fovea using ophthalmoscope. Ask the patient to look at the bright light of the ophthalmoscope for 10 seconds. [1] Time taken to read any three letters of the pre-test visual acuity is ...
