    Abstract:

    To study the experimental method of inducing the chronic intraocular hypertension in rat eyes. · METHODS: Twenty Wistar rats were randomly divided into ocular hypertension and sham control groups. Intraocular pressure (IOP) was raised by electrocoagulating at least 3 episcleral and limbal veins on the right eye of each rat in ocular hypertension group and its contralateral eye was used as control. At 1, 2, 3, 4 and 8 week after the electrocoagulation of the veins, IOP were measured. · RESULTS: The treatment of electrocoagulation caused a significant IOP increase of the right eyes over the baseline, over the contralateral eyes, and over the sham control eyes (repeated measures ANOVA, P <0.001). At 1 week, IOP was 30.12±5.18mmHg, and maintained the high IOP up to 8 weeks. · CONCLUSION: The chronic intraocular hypertension model could be successfully created by electrocoagulating three or more episcleral and limbal veins.
