Purpose. To report choroidal thickness and volume in healthy eyes using swept source optical coherence tomography (SS-OCT). Methods. A prospective observational study of 122 patients examined with swept source OCT (DRI-OCT, Topcon, Japan). In each eye, we performed 256 horizontal scans, 12 mm in length and centered on the fovea. We calculated choroidal thickness manually with a built-in caliper and automatically using DRI-OCT mapping software. Choroidal volume was also automatically calculated. We measured axial length with optical low-coherence reflectometry (Lenstar LS 900, Haag-Streit, Switzerland). Results. The choroid has focally increased thickness under the fovea. Choroid was thinnest in the outer nasal quadrant. In stepwise regression analysis, age was estimated as the most significant factor correlating with decreased choroidal thickness (F = 23.146, P < 0.001) followed by axial length (F = 4.902, P = 0.03). Refractive error was not statistically significant (F = 1.16, P = 0.28). Conclusions. SS-OCT is the first commercially available system that can automatically create choroidal thickness and volume maps. Choroidal thickness is increased at the fovea and is thinnest nasally. Age and axial length are critical for the estimation of choroidal thickness and volume. Choroidal measurements derived from SS-OCT images have potential value for objectively documenting disease-related choroidal thickness abnormalities and monitoring progressive changes over time.

Swept-source optical coherence tomography enables exact visualization of the outer choroidoscleral boundary. Suprachoroidal layer consisting of two bands has been recognized, the upper of which is hyperreflective and the lower of which is hyporeflective. It may be supposed that the lower hyporeflective band corresponds to suprachoroidal space, which was not earlier visualized in vivo in eyes without choroidal effusion. Suprachoroidal layer in myopic and emmetropic healthy subjects has been rarely observed. We observed it more frequently in different macular diseases.

Purpose: To report a case of treatment of a full-thickness macular hole, which appeared after 10 months of anti-VEGF treatment in neovascular age related macular degeneration (nAMD). Methods: The patient was diagnosed as type 1 nAMD. The coexisting vitreomacular traction caused a full thickness macular hole after 10 months of treatment. Patients: A 68-year-old woman treated with anti VEGF. Results: Vitrectomy with the temporal inverted ILM flap technique succeeded in closing the hole. Further anti-VEGF treatment followed. Conclusion: FTMH is a rare complication or coexistence in nAMD. Vitrectomy and continuous anti-VEGF treatment might result in satisfactory anatomical and functional results.

<b><i>Purpose:</i></b> To describe retinal morphology and vision recovery after spontaneous closure of full-thickness macular hole (FTMH). <b><i>Materials and Methods:</i></b> Retrospective, observational study. From a database containing 750 FTMH, we included 23 cases. All patients had a complete ophthalmic examination. Swept-source optical coherence tomography angiography was performed. <b><i>Results:</i></b> Prior to spontaneous closure in 11 women and 12 men (mean age 67 years), the mean minimum FTMH diameter was 201 μm, and mean base FTMH diameter was 638 μm. Visual acuity improved from 0.29 Snellen to 0.47 Snellen (<i>p</i> = 0.001) after 6 months and showed no further improvement. Spontaneous closure of FTMH was associated with vitreous detachment in less than half of the cases. Irregularities in the deep vascular layer and hyporeflective areas in the choriocapillaris were noted. <b><i>Discussion:</i></b> Equal sex distribution of spontaneous closures (1:1) differs from the high prevalence of females seen in the literature. Complete visual recovery is uncommon in cases of spontaneous closure of FTMH. It might be explained by prolonged defects of the choriocapillaris layer. These findings, along with the evolution of the various morphologies reported in the study, could possibly suggest that delaying vitrectomy while hoping for spontaneous closure might not be justified.
