Abstract
Purpose:
Degenerative retinoschisis (RS) can easily be confused with old retinal detachment (ORD). The differential diagnosis between RS and ORD is usually made on the basis of clinical examination. The present study aimed to evaluate the morphological findings of color fundus photographs and different OCT devices (Cirrus®, Topcon®, Spectralis®) in eyes with RS and ORD.
Methods:
In this prospective observational study, 57 eyes of 50 patients with peripheral RS or ORD were included. The study was performed at the Department of Ophthalmology and Optometry, Medical University of Vienna. Apart from clinical examination, Heidelberg Spectralis OCT volume and single line scan using follow-up mapping and eye tracking method, Zeiss Cirrus OCT 5-Line scan and Topcon DRI-OCT 12mm single line scan were performed. Furthermore Optomap color fundus photograph was taken in each follow-up visit. Patients were followed-up until 6 months after initial visits.
Results:
Mean age of the patients was 60.75 ± 16.73 years. All patients showed similar appearance in the color fundus photograph images. Despite a peripheral localization, OCT imaging was possible in all included patients. In OCT images, 37 eyes showed typical splitting in the outer nuclear layer/ outer plexiform layers whereas in 20 eyes, a full retinal detachment was observed. In the funduscopy or fundus photography image not detectable progression of the disease was observed in 2 eyes using follow-up mapping of Spectralis OCT.
Conclusions:
All OCT devices provide helpful information regarding diagnosis and differentiation between RS and ORD. Further Topcon OCT and Spectralis OCT scans are beneficial for evaluation of vitreous detachment or traction. The Spectralis OCT with follow-up mapping can provide additional information of progression and can be applied to indicate and monitor treatment modality s.a laser photocoagulation or surgery.
