A 25-year-old male presented with decreased vision 2 days after right eye open globe injury (OGI) repair. Patient's records mentioned OGI (Type A Zone I Grade III)[1] OD following a trivial blunt trauma while rubbing his eye by his finger. The patient denied any other history of ocular trauma. On ocular examination, his best corrected visual acuity was 20/400 OD (+11.0 DS/-4.5 × 90 DC) and 20/30 OS (-3.5 × 90 DC). Slit-lamp examination revealed repaired limbal perforation in the right eye, with iatrogenic superior aniridia [Figure 1]a. There was presence of 360° peripheral corneal thinning adjacent to limbus, with superficial vascularization and lipid deposition at its leading edge in both eyes [Figure 1]b, [Figure 1]c, [Figure 1]d, [Figure 1]e, [Figure 1]f. Corneal thinning was maximum in superior cornea, with intact overlying epithelium. Crystalline lens was absent in the right eye; and might have expulsed at the time of primary repair. Fundus examination and systemic history were unremarkable. Corneal topography revealed “against-the-rule” corneal astigmatism of 4.8 Diopters OS (K1 = 41.6D@92.6°; K2 = 46.4D@ 2.6°) [Figure 2]. Anterior segment optical coherence tomography of the left eye revealed peripheral corneal thinning [Figure 3]. Both the investigations were distorted for right eye. A diagnosis of bilateral Terrien's Marginal Degeneration (TMD) was made. Advanced TMD led to globe rupture in the area of superior thinning following eye rubbing in our patient. Patient was kept under close observation and planned for sclerokeratoplasty with aniridia scleral-fixated intraocular lens OD.

  Discussion Top


TMD is a rare, slowly progressive, bilateral peripheral ectatic disorder seen in males in third to fifth decade of life. It may cause decreased vision due to “against- the-rule” astigmatism.[2],[3] Imbalance in corneal homeostasis has been believed to cause corneal stromal loss in TMD, causing spontaneous perforation in 9% of such cases.[4],[5] Early diagnosis and close observation is essential in TMD to prevent ocular injuries spontaneously or following trivial trauma.
