Ancillary Testing | Anterior segment imaging was acquired, including photography (Figure 1), optical coherence tomography (Triton; Topcon, Tokyo, Japan), and Pentacam HR (Oculus, Wetzlar, Germany). See Figures 2-3. Optical coherence tomography scans of the macula and optic disc were normal in both eyes. Extensive blood investigations were ordered, including urea and electrolytes, full blood count, liver function, bone profile, random glucose, C-reactive protein, erythrocyte sedimentation rate, Borrelia burgdorferi antibodies, lipid panel (including apolipoprotein A-1), serum protein electrophoresis, antinuclear antibody, caeruloplasmin, angiotensin converting enzyme, ferritin, transferrin, transferrin saturation, iron, and heavy metal screen for lead and copper. Urine amino acids, glycosaminoglycan, creatinine, and glycosaminoglycan:creatinine ratio were also ordered to exclude gross amino acid disorders and mucopolysaccharidoses. Blood and urine testing revealed no significant abnormalities. Because infectious etiology was deemed unlikely, corneal cultures were not acquired. | |
