Ophthalmic Evaluation of Children from the Tibet Plateau with Congenital Heart Disease

Purpose： To perform ophthalmic examinations to evaluate the ocular characteristics of children living in the Tibet plateau and diagnosed with congenital heart disease. Methods： Children with congenital heart disease underwent a conventional ocular examination including distant acuity test, slit-lamp examination, fundus examination, non-contact in- traocular pressure measurement, measurement of corneal thickness, and fundus photography. Results： Forty-two Tibetan children, aged between 4 and 18 years and diagnosed with congenital heart disease, were en- rolled in this study. The percentage of low visual acuity was 4.76%, mean intraocular pressure was （13.67±2.15） mmHg, average corneal thickness was （492.55±33.79） μm, 96.43% had an anterior chamber depth of 1/2 corneal thickness （CT）, and 35.7% had an obvious fundus vascular tortuosity.
