In other words, although the same advice was given to all the patients, probably some patients complied strictly, whereas others did not.Ī mechanical sensory device mounted on the patient’s head to automatically monitor the head position or the nursing records of direct observation of patient’s position can both be used to obtain an index of adherence. However, in these studies the patients’ actual positions were not assessed, and thus the researchers did not actually test the positions adopted by the patients. Shortening the duration of FDP and the use of alternate positions, such as avoidance of the supine or face-up positions, has been proposed after comparisons with strict FDP. But FDP is inconvenient and not readily tolerated thus, the optimal method and duration of FDP have been debated for many years, especially after MH surgery. Adherence also varied with time, being worst at midnight and declining over time.įace-down positioning (FDP) is recommended after vitrectomy and gas tamponade for rhegmatogenous retinal detachments (RRDs) or for macular hole (MH) surgery. We found patients age had no effect on adherence. Adherence was higher in female than in male patients, and higher in patients with MH than in those with RRD. Adherence to the FDP varied considerably among patients. There were diurnal variations in adherence, being highest in the evening and significantly lower at midnight, and we evidenced a decline in adherence over time, with it being significantly low on the last follow-up day. The adherence was significantly better after MH surgery (90.8 ± 11.7) than after RRD surgery (87.5 ± 12.5 P < 0.02). Female patients (90.8 ± 10.0) had significantly better adherence than male patients (86.7 ± 13.3 P < 0.02, U test). Adherence was assessed and recorded four times per day for 3 days postsurgery. We studied 119 female and 177 male patients who had undergone primary vitrectomy and gas tamponade for a macular hole (MH) or for rhegmatogenous retinal detachments (RRDs). To determine the adherence to the face-down positioning (FDP) in 296 patients who had undergone vitrectomy and gas tamponade.
