Quantitative optical density (OD) measurement of sub- or intraretinal fluid on optical coherence tomography (OCT) is a novel imaging biomarker that has been reported to differentiate macular diseases and may have prognostic significance. Patients with macula involving rhegmatogenous retinal detachment (RRD) typically have an uncertain visual prognosis. We evaluated the correlation of subretinal OD and visual outcomes following macula off RRD repair.
A retrospective, multicenter observational study of patients with primary macula involving RRD who had spectral domain OCT (SD-OCT) on presentation and after subsequent surgical repair. Patients with history of other ocular disease, redetachment following repair, and poor-quality OCT scan were excluded. OD values of the vitreous and subretinal fluid (SRF) were obtained using ImageJ (National Institutes of Health) and an OD ratio (ODR) of SRF to vitreous was calculated. Patients were divided into 3 groups based on reported duration of RRD symptoms: acute (<1 week), subacute (1 week -1 month), and chronic (>1 month).
Thirty-nine eyes of 39 patients met inclusion criteria with an average age of 58 years (range 25-85). Between the 3 groups, patients did not differ in age, presenting visual acuity (VA), extent of retinal detachment in clock hours, or subfoveal SRF height (all p>.05). Mean ODRs for the acute (0.63±0.32), subacute (0.63±0.33), and chronic (0.56±0.22) groups were not significantly different (p=0.09). ODR and SRF height did not correlate with post-operative VA (p=0.09).
ODRs of SRF to vitreous did not correlate with reported duration of RRD symptoms or post-operative VA in this retrospective study. Further prospective studies should be undertaken to better evaluate OD of SRF as a prognostic biomarker for macula involving RRDs.
