Purpose To study outcome and spectral domain optical coherence tomography (SD-OCT) macular findings in patients who underwent surgery for spared macula giant retinal tear (GRT) retinal detachment. Methods a retrospective study of 12 patients with spared macula giant retinal tear (GRT) retinal detachment who underwent vitrectomy (N=7), vitrectomy with an encircling scleral buckle (n=4) and scleral buckle (n=1) with at least 3 months follow up after silicon oil removal (SOR) . Post-SOR macular SD-OCT scans were studied in all eyes. Results Final reattachment achieved in all eyes with single primary surgery. Post-SOR SD-OCT macular finding was photoreceptors layer disruption in 6 eyes, epiretinal membrane (ERM) in 4 eyes, Macular hole in 1 eye and choroidal neovascularisation in 1 eye. Significant correlation found between final Best-Corrected Visual Acuity (BCVA) and macular pathology on SD-OCT p value (0.048). Conclusion SD-OCT plays a high role in diagnosis of macular alterations that can be associated with poor functional outcome in anatomically successful GRT surgery with spared macula pre-operatively.

Purpose To describe spectral domain optical coherence tomography (SD-OCT) and enhanced depth image OCT (EDI-OCT) findings of multifocal serpiginoid choroditis (MSC) , including affected layer of retinal involvement, changes at the vitreoretinal interface, and response to therapy. Methods A retrospective review of 20 eyes (14 patients) with MSC. Each patient underwent a complete ophthalmologic examination, fundus photography, fundus autoflorecence (FAF) and OCT imaging of the affected retina at the initial visit and on each follow-up. Results In acute stage, SD-OCT showed hyperreflective areas involving the outer retinal layers which include retinal pigment epithelium (RPE), photoreceptor outer segment tips (POST), inner segment–outer segment (IS/OS) junction, external limiting membrane (ELM), and outer nuclear layer (ONL) with choroidal and intraretinal layer cells infiltrate. EDI-OCT showed increase choroidal thickness. As the lesions began to heal, irregular, knobby elevations of outer retinal layers appeared (RPE, POST, IS/OS junction, and ELM could not be distinguished) with significant decrease in choroidal and intraretinal cells. On complete healing, loss of RPE, POST, IS/OS junction, and ELM in SD-OCT scan and absent of the choroidal and intraretinal cells and continous hyperreflactivity of the choroid (increased penetrance). Conclusion SD-OCT and EDI-OCT provides high-resolution detail regarding ultrastructural changes in vitreoretinal interface, outer retina and choroid during the course of the lesion. Serial SD-OCT and EDI-OCT also provides further insight into response to therapy by observing choroidal and intraretinal cells.
