Terrien marginal degeneration

Clinical Application of Optical Coherence Tomography in the Corneal Degenerations

“…The pathology has been associated with arthritis and meibomian gland dysfunction. TDM is more frequent in middle-aged males but can occur at any age and in females [21].…”

“…TMD is a lipid keratopathy [19]. The slit-lamp biomicroscopy evaluation displays lipid depositions at the edge of the peripheral corneal thinning [21,22] (Figure 15). This lipid accumulation produces yellow-white stromal opacities [22] with superficial neovascularization.…”

“…This lipid accumulation produces yellow-white stromal opacities [22] with superficial neovascularization. Histopathological exams demonstrate intracellular and extracellular vacuoles [21] charged with lipids in the corneal stroma. There is stromal fibrillary degeneration with fatty infiltration of collagen fibers [21,22].…”

“…Histopathological exams demonstrate intracellular and extracellular vacuoles [21] charged with lipids in the corneal stroma. There is stromal fibrillary degeneration with fatty infiltration of collagen fibers [21,22]. This stroma degradation produces a decrease in the number of lamellas.…”

“…Clinical Application of Optical Coherence Tomography in the Corneal Degenerations DOI: http://dx.doi.org/10.5772/intechopen.84244 TMD corneal changes can produce an increase in the corneal astigmatism [21], which clinically manifests with a visual acuity decreased. Topography evaluation is essential for a complete pathology study [23].…”
