Evaluate a wide field (200°) imaging system (Optos, UK ) using a scanning laser ophthalmoscope (SLO) as a diagnostic tool for retinal breaks and retinal detachment.
All patients referred for retinal detachment from November 2006 to April 2007 were examined by one retinal surgeon who also performed the fundus drawing. An SLO imaging was performed by an orthoptist in training and retrospectively reviewed by a resident, both the orthoptist and the resident being unaware of the details of the retinal examination. The number of breaks and the extent of the detachment on the drawing were compared with the findings detected on the SLO image.
56 eyes with retinal detachment were documented. In 40 of 56 eyes the retinal breaks could be detected on the SLO images. The retinal breaks situated superiorly between 11 and 1 o’clock and inferiorly between 5 and 7 o’clock were missed on the SLO images. Two retinal detachments, one superior and one inferior, were not detected on the SLO images.
SLO image analysis enabled correct diagnosis of retinal breaks in more than 70%. The retinal detachment was detected on the SLO image in more than 95%. The sensitivity of the wide field SLO imaging system appears to be suitable for screening purposes of retinal detachment although it may not replace a thorough preoperative clinical examination. Further work is necessary to evaluate its potential use in patient education and training of vision professionals.
