Abstract

Purpose: To evaluate the feasibility, efficacy and safety of strict prone posturing taken for 2 hours after operation in preventing the occurrence of unintentional retinal displacement in elderly patients operated on for retinal detachment (RD).

Methods: Twenty patients aged 60 or more with diagnosis of macula-off RD were asked to keep a strict face-down posturing for 2 hours after vitrectomy and 20% sulfur hexafluoride tamponade. IOP was measured immediately before and after surgery and after the 2-hour posturing. A questionnaire was administered to each patient to evaluate the rate of discomfort experienced because of the face-down posturing. Unintentional displacement of the retina was assessed by evaluating the presence of retinal vessel printings on fundus autofluorescence images taken 4 weeks after operation.

Results: The 2-hour posturing was generally well-tolerated. A mild neck pain was the most common reported symptom. Only a few patients experienced moderate breath shortness while posturing and none had to break the posturing because of respiratory problems. Intraocular pressure (IOP) measured before operation (11.7 ± 2.6 mmHg) was significantly different from IOP recorded at the end of surgery (18.9 ± 4.9 mmHg) and from IOP measured 2 hours after surgery (16.8 ± 4.7 mmHg, P<0.05, Friedman test). IOPs measured immediately and 2 hours after surgery did not differ significantly. Fundus autofluorescence imaging showed RVPs in 7 eyes.

Conclusions: This study shows that a 2-hour face-down posturing is effective in reducing the rate of retinal displacement in patients operated on for rhegmatogenous retinal detachment using vitrectomy and SF6 20%. A 2-hour face-down posturing is feasible for elderly patients and does not appear to cause unwanted, post-operative IOP raises.
