Figure 19 Fifty-eight-year-old male with misdiagnosed Fusarium keratitis. (a) Moderately dense full-thickness central corneal infiltrate (black arrow) and small hypopyon (white arrow). (b) Confocal microscopy shows multiple linear structures with branching at 45 , consistent with Fusarium species (later culture proven). (c–e) OCT showed a remarkable funnel of fibrin (white arrow) from the base of the ulcer to the pupil. From Steinert, R. E. and Huang, D. (2008). Anterior Segment Optical Coherence Tomography.

Figure 20 Fifty-four-year-old female with severe infectious keratitis. Gram stain of the corneal scrapings showed gram-negative rods, and cultures were positive for Pseudomonas. (a) Large infiltrate with large hypopyon. (b) Vertical orientation of OCT shows 60–70% anterior chamber hypopyon. Note white arrow representing interface between cornea (anterior) and hypopyon (posterior). (c) Significant stromal thinning with 270 mm shown by caliper tool (blue bar). Note that normal corneal thickness is about 540 mm. (d) The patient was admitted and treated aggressively; 1 week later, the thinning was nonprogressive. (e) Over a 2-month period, the area of corneal thinning gradually improved to nearly normal thickness and the anterior chamber hypopyon regressed as shown in this high-resolution corneal quadrant image. Each image represents a corneal section through a particular axis which is shown above the image. From Steinert, R. E. and Huang, D. (2008). Anterior Segment Optical Coherence Tomography.

Figure 23 Zig-zag shaped PKP femtosecond laser incisions. (a) Slit lamp photo showing well-aligned incision with smooth transition from donor to host. (b) Angled anterior incision is clearly visible (black arrow). (c) OCT at 1 month postoperatively
shows excellent alignment of donor and host, both at the anterior and posterior surfaces (white arrows). (d) OCT at 3 months shows higher signal return at incision indicating stronger wound healing as compared to postop month one. (e) The rainbow color image highlights the zig-zag incision. (f) Suture depth is noted at 50% depth with perfect posterior tissue alignment and apposition. From Steinert, R. E. and Huang, D. (2008). Anterior Segment Optical Coherence Tomography.
