ABSTRACT
Background:During hemodialysis there is decrease in both systolic blood pressure (SBP) and diastolic blood pressure (DBP) and hence Mean Arterial Pressure (MAP) due to decrease in body fluid volume. Due to reduc?on in MAP there is decrease in Mean Ocular Perfusion Pressure (MOPP) and also there is increase in IOP during dialysis. Objec?ve:To study changes in MOPP and IOP among pa?ents undergoing hemodialysis Methods:An observa?onal study was carried out among 100 pa?ents undergoing hemodialysis Under asep?c condi?on, Proparacaine eye drops were ins?lled in both eyes, IOP was measured by Schiotz Indenta?on Tonometer 30 min before, during hemodialysis and 30 min a?er hemodialysis in supine posi?on. Tonometer was sterilized by Isopropyl alcohol and was washed with normal saline before using on next pa?ent. Systolic and diastolic blood pressure were measured by using sphygmomanometer 30 min before, during and 30 min a?er hemodialysis. Results:The varia?ons in the SBP, DBP and MAP before, during and a?er hemodialysis were not sta?s?cally significant (p>0.05). There was significant differences for IOP between before, during and a?er hemodialysis and same for MOPP except before and 30 min a?er hemodialysis (p < 0.0001). Conclusion:Significant fluctua?ons were seen from the present study in the intra-ocular pressure and mean ocular perfusion pressure during, before and a?er hemodialysis.
