Descriptive analysis of the macular pathology in patients with tilted disk syndrome by images obtained with optical coherence tomography (OCT)
Hospital Virgen de la Victoria. Malaga. Spain
A randomized retrospective study of 40 eyes in 27 patients, with uni- or bilateral tilted disk syndrome, followed in the Medical Retina Unit. Inclusion criteria were the presence of an obliquely directed long axis and antero-posterior tilting of the optic disk detected by fundus examination color retinography and retinal angiography. We studied the presence of macular complications by OCT imaging using the macular cube 512x128 scan and the 5-line raster scan. Choroidal neovascularisation (CNV), serous retinal detachment (SRD), foveoschisis (FC), lamellar macular holes and epiretinal macular membrane (ERM) were included.
The study included 27 patients with tilted disk syndrome (16 women [59,25%] and 11 men [40,75%]). The mean age was 53,2 ± 7,4 years, the best corrected visual acuity (BCVA) was 0,6 ± 0,2; and ranged from 0,4 to 0,8. The spherical equivalent refractive error ranged between – 1,5 and -7,5 diopters (mean, -5 diopter ± 1,75). The mean axial length was 26,4 ± 1,89 mm. Of the 40 eyes with tilted disk syndrome, 27 eyes presented macular complications (67,5%). CNV was observed in 8 out of these 27 eyes (29,6%), SRD in 11 eyes (40,7%), FC in 3 eyes (11,1%), and ERM in 6 eyes (22,2%).
We confirmed a high incidence (67,5%) of macular complications in tilted disk syndrome as reported previously in other studies. The most common macular complication in our study was the presence of SRD. The OCT facilitates the early detection of potentially severe macular anomalies difficult to detect by conventional fundus examination.
