The Clinical Observation of the Effect of Age-Related Cataract Level on Corneal Endothelium

Objective To observe the corneal endothelium density and morph change and to approach the effect of age-related cataract level on corneal endothelium.Methods One hundred patients with age-related cataract whose one eye vision was lower than 0.2 and the other higher than 0.6.Each patient's two eyes were divided into two groups:the eye with vision lower than 0.2(A group) and the eye with vision higher than 0.6(B group).The two groups 'corneal endothelium density,coefficient of variation (CV) and percentages of hexagonal cell were observed and analyzed. Results In group A:the corneal endothelium density was 2297.65±364.66 (cells/mm~2),CV was(56.65±7.28) %,and Percentages of hexagonal cell was(35.06±5.45)%.In group B:the corneal endothelium density was 2570. 46±340.25 (cells/mm~2),CV was(47.59±7.03%),and Percentages of hexagonal cell was(41.97±5.19)%.There was statistical significance between the two groups in the above three indexes(P0.05).Conclusion As the age-related cataract progresses,corneal endothelium density decreases,CV increases and percentages of hexagonal cell decreases. There is relationship between the damage of corneal endothelium and the progress of age-related cataract.
