Postoperative pain is predictable and therefore preventable; its management should be a priority. Posterior segment surgery is an underestimated source of pain. The objective of this work is to highlight the intensity of postoperative pain in this type of surgery. This was a 6-month prospective descriptive longitudinal study. Involving 67 patients operated for a pathology of the posterior segment. The simple verbal scale was used to assess pain in the postoperative period at HO, H8, H16 and H24. During the period, posterior segment surgery accounted for 1.88% of the institute's surgical activities. Male predominates with 88%; The mean age was 45.7 years with extremes of 7 and 75 years, vitrectomy accounted for 71.6% and scleral cryoindentation 28.4%. Peribulbar anaesthesia combining bupivacaine and xylocaine was the most commonly used with 80.6%. Intravenous injection of morphine intraoperatively was associated with peribulbar anesthesia in 19.4% of cases of scleral cryoindentation. In the immediate postoperative period (H0), pain was intense in 37%, moderate in 52% and low in 11% of patients after cryoindentation while it was absent in 52% and low in 48% of patients after vitrectomy. At H8 and H16, severe pain was reported in 47% of cryoindentations; It was reported as weak to moderate after vitrectomy in 91.66%. At H24, after treatment, patients had moderate pain in 69%, and low pain in 31% after cryoindentation; It was low in 85.71% after vitrectomy. This work allowed us to highlight the feelings of patients operated on in the posterior segment and to propose a postoperative management protocol.
