Two brothers with reduced vision

6-year-old boy and his 18-month-old younger brother presented to outpatient department with decreased vision and abnormal appearance of eyes since early childhood. They were otherwise healthy and born at term out of a consanguineous marriage. The best-corrected visual acuity in the elder brother was 6/12, N8 right eye and 6/36, N10 left eye with refractive error of + 7 D sph/+2 D cyl axis 90° in both eyes. Refractive error in his sibling was + 8 D sph/+2 D cyl axis 180° both eyes. In both children, ocular examination revealed small, horizontally oval corneas [8–9 mm horizontal diameter; [Figure 1] with wide limbal zone. There were superficial stromal central nebulomacular corneal opacities in both eyes without any associated vascularization. Intraocular pressures were normal with clear lens and clear red reflex posterior segment findings were with in normal limits
