Despite being treated with intensive antibiotics and lubricants, the cornea thinning progressed to cornea perforation with flat anterior chamber (AC) (Figure 1(a)). He was able to regain his vision to 6/9 with presence of stable cornea patch graft during last review (Figure 1(b)).

(a) Peripheral cornea thinning from12 to 5 o'clock. (b) Post banana shaped corneal patch graft.

There's adjacent cornea epithelial defect but no cornea perforation seen (Figure 2(a)). He underwent conjunctival resection and cryotherapy twice and amniotic membrane patch graft once before a banana shaped corneal lamellar patch graft was performed (Figure 2(b)).

Despite this treatment, 3 months later, his eyes showed disease progression where there was continuous cornea melting to almost 360 degree (Figure 3(a)) for which he underwent conjunctival resection. However, the cornea keratolysis worsened and he was subjected to tectonic keratoplasty (cornea scleral patch graft) (Figure 3(b)).

Peripheral edge of left cornea had slow leak but with deep anterior chamber (Figure 4(a)). He was scheduled for left eye cornea banana-shaped patch graft (Figure 4(b)).

(a) Presence 2 area of scleral thinning at inferonasal quadrant. (b) Immediate post-operative scleral patch graft extending up to inferonasal limbal area. (c) Post-operative 5 months once the scleral melting has stabilized.

Right eye examination showed two locations of scleral thinning with visible uveal tissue at inferonasal quadrant with adjacent cornea scarring (Figure 5(a)). She underwent cornea patch graft for the scleral thinning (Figure 5(b)). Subsequently, no further melting was noted after 5 months post-operative period (Figure 5(c)).
