Purpose Terrien marginal degeneration is a rare idiopathic form of corneal degeneration that affects peripheral cornea, it occurs at any age and 75% of patients are males. This condition is most commonly bilateral and asymmetric. Patients are often asymptomatic but they may also complain of irritation of the eye and progressive loss of visual acuity due to oblique astigmatism. Rarely the disease may lead to corneal perforation but may also occur spontaneously or secondary to trauma. The most important corneal modifications in Terrien marginal degeneration, frequently located superonasaly, are observed in the stroma showing yellow – white opacities composed of lipids with associated vascularization. Spectral Domain OCT because of its capacities to describe corneal anatomy might be useful in the diagnosis of the Terrien marginal degeneration. Methods We present a case of a 75 year old male who was examined and followed during several months in the department of ophthalmology, Lozano Blesa University Clinic Hospital, Zaragoza, Spain, with slit lamp, corneal topographic maps and spectral domain‐ OCT. Results SD‐OCT confirmed the peripheral corneal thinning seen with corneal topographic map and slit lamp. It showed intact epithelial and endothelial layers surrounding the stromal cavity formation, and a perforation of the endothelium underneath this cavity. Conclusions We point out the utility of spectral domain optical coherence tomography in the diagnosis and follow‐up of cavity formation in the peripheral cornea in Terrien marginal degeneration.
