Patient ignorance is the main reason for treatment delay in primary rhegmatogenous retinal detachment in The Netherlands.

AIMS: Treatment delay of progressive vision-threatening conditions should be minimal. In this study, the treatment delay of patients with a rhegmatogenous retinal detachment (RRD) undergoing retinal detachment surgery was quantified, and causes for this delay were evaluated. MATERIALS AND METHODS: Consecutive patients (n=205) presenting with a primary RRD between June 2006 and June 2007 at the tertiary referral center (TRC) were interviewed. Five categories of delay were discerned in the following: 'patient delay,' 'general practitioner's delay,' 'referring ophthalmologist's delay,' 'delay at the TRC' and 'delay before surgery at the TRC'. In addition, overall delay was calculated. RESULTS: In total, 186 eyes were included in the analysis. Median overall delay between the patients' first symptoms and RRD surgery was 10 days. Almost 60% of this overall delay time was due to patient delay and the delay of the general practitioner. More than 50% of patients had a delay owing to unawareness of the symptoms. The median patient delay was significantly lower in patients with a vitreous hemorrhage and in patients with a history of a RRD in the fellow eye. CONCLUSIONS: The major reason for patient delay with a RDD was the patients' unawareness and unfamiliarity with the symptoms of a retinal detachment.

Risk factors for redetachment and worse visual outcome after silicone oil removal in eyes with complicated retinal detachment.

PURPOSE: The goal of this study was to identify risk factors for redetachment and/or a worse visual outcome after silicone oil removal (SOR) for complicated retinal detachment. METHODS: The authors retrospectively analyzed 287 consecutive eyes with SOR between January 1999 and December 2003. RESULTS: Anatomic success after SOR was achieved in 81% of the eyes. The overall anatomic success at the end of follow-up was 94%. Postoperative ocular hypertension was found in 8% of the eyes, hypotony in 6% of the eyes, and keratopathy in 29% of the eyes. After SOR 43% of the eyes had an improvement in visual acuity of at least two Snellen lines. After multivariate analysis, male sex, the presence of preoperative rubeosis, and proliferative diabetic retinopathy (PDR) were found to be risk factors for recurrent retinal detachment. Male sex, preoperative visual acuity of <0.1 Snellen lines, PDR, the performance of three more operations, any size of retinectomy, and hypotony were found to be associated with a poor visual outcome of Snellen visual acuity <0.1. CONCLUSIONS: Retinal detachment after SOR in the current unselected series of eyes occurred in approximately 20%, which is comparable to the Silicone Oil Study reports, published approximately 20 years ago. However, preoperative selection was then made, and less than 50% of the silicone oil-filled eyes had SOR. The higher overall anatomic success in the current study may be due to improved vitreoretinal surgical techniques.
