Post-operative hospitalization in retinal detachment correlation to recurrences.

Purpose: To evaluate relationships between the incidence of re-detachment and post-operative days of hospitalization in patients with diagnosis of retinal detachment (RD) who underwent surgery or ab-externo approach (scleral buckling and encircling) or ab-interno approach (vitrectomy and oil-gas tamponade). Methods: The retrospective study included 268 patients (268 eyes) with diagnosis of primary RD: 127 males (47%) and 141 (53%) females, mean age of 64.1±17.3 years. 46 patients (17%) underwent a surgical ab-externo approach (group A), while 222 patients (83%) underwent to an ab-interno surgical approach. In all cases RD were graded according “Retinal detachment grading system of Royal College of ophthalmologists” and treated within 5 days after diagnosis. In all patients, after the primary operation retina was completely attached. Redetachment (RT) related to surgical failure were considered within 30 days after primary operation. Results: In the group 1 global RT rate was 3.5% (4.17% for ab-interno technique and 0% for ab-externo techniques). In the group 2 global RT rate was 1.33% (1.49% for ab-interno technique and 0% for ab-externo techniques). In the group 3 global RT rate was 3.80% (4.62% for ab-interno techniques and 0% for ab-externo techniques). In the group 4 global RT rate was 12.28% (14.29% for ab-interno techniques for 6.67% ab-externo techniques). Group 1 incidence of RT is comparable to other groups and less than group 4. Conclusions: The incidence of retinal redetachment (RRD) is not increased in day surgery mode. Patients should be discharged in shortest time to reduce medical cost and problems related to hospitalization. Further studies are needed for patients’ security.
