Macular pseudoholes (MPHs) and lamellar macular holes (LMHs) have been recently defined according to spectral domain optical coherence tomography (SD-OCT) criteria. A major feature for differentiating an MPH from an LMH remains the loss of foveal tissue. The anatomy of the foveola is peculiar with the macular pigment (MP) embedded in a very thin layer of tissue underlying the internal limiting membrane and mainly constituted of a specialized group of Müller cells and Henle’s fibers. Despite the near microscopic resolution (≈5–7 μm) and the capability to visualize the outer retina in detail, SD-OCT may fail to ascertain whether a very small loss of this foveolar tissue has occurred. Blue-fundus autofluorescence (B-FAF) imaging is useful in this respect because even very small loss of MP can be identified, suggesting a corresponding localized loss of the innermost layers of the foveola. A definition of MP loss would help differentiating an LMH from an MPH where B-FAF imaging will be negative.

Purpose. To describe the characteristics of idiopathic macular holes (MH) on optical coherence tomography (OCT) and correlate OCT with clinical assessment.Design. Cross-sectional chart review and OCT assessment.Participants. Sixty-seven eyes with a clinically diagnosed idiopathic MH with available OCT data.Methods. A retrospective chart review and OCT assessment.Results. Based on OCT grading, 40 eyes had a full-thickness macular hole (FTMH) and 21 eyes had a lamellar macular hole (LMH). Clinical exam and OCT assessment agreed in 53 (87%) eyes when assessing the extent of MH. Six eyes (14.6%) in the FTMH group, and 3 eyes in the LMH group (14.3%) had persistent vitreomacular traction. Thirty-seven eyes (92.5%) in the FTMH group and 11 eyes (52.4%) in the LMH group had associated intraretinal cysts. Two eyes (5.0%) in the FTMH group and zero eyes in the LMH group had subretinal fluid. Intraretinal cysts were found to be more frequently associated with FTMH than with LMH (P<0.001).Conclusion. This paper described OCT findings in a group of patients with clinically diagnosed MH. A high level of correlation between clinical assessment and OCT findings of LMH and FTMH was observed, and intraretinal cysts were often present in FTMH.

Abstract Background: Eales disease primarily affects the peripheral retina. However, posterior involvement can be seen. Macular epiretinal neovascularization is not commonly seen in Eales disease. This report highlights the morphology and origin of macular epiretinal neovascularization (ERN) using multimodal retinal imaging, including optical coherence tomography angiography (OCTA). Results: A 35-year-old man with no history of systemic disorders presented with gradual decrease of vision in his left eye. Fundus examination of his right eye showed peripheral sclerosed blood vessels, neovascularization of the optic disc and elsewhere, and macular ERN. The view of the left fundus was limited by vitreous haemorrhage. Fluorescein angiography (FA), of the right eye showed widespread peripheral capillary nonperfusion and leakage of dye from the retinal neovascularization and macular ERN. Macular Spectral domain optical coherence tomography (SD-OCT) of the right eye showed an epiretinal membrane and the presence of epiretinal neovascular lesions extending above the internal limiting membrane towards the vitreous. Optical coherence tomography angiography (OCTA) showed multiple tiny blood vessels at the macula that arose from the superficial retinal capillary plexuses and extended toward the vitreous. The corresponding B-scan showed flow signal through these vessels and the signal extend above the internal limiting membrane. Systemic work-up was negative except for strongly positive tuberculin skin testing giving the classic diagnosis of Eales disease. Patient was started on empirical anti-tubercular therapy and oral corticosteroids. Scatter laser photocoagulation was applied to nonperfused retinal zones. Despite adequate scatter laser ablation, the ERN failed to regress fully. Conclusions: Macular ERN can be seen in cases of classic Eales disease. The origin of macular ERN in our case was shown to be from the superficial retinal capillary plexuses. We also noted the slower regression rate of macular ERN as compared to the major neovascularizations of the optic disc and peripheral retina. Further research is needed to establish the pathogenesis of ERN and its optimal management.

Morphofunctional Analysis

Purpose. To evaluate the role of microperimetry and optical coherence tomography (OCT) in the morphofunctional analysis of the retina after surgical treatment of idiopathic macular holes (IMH). Materials and methods. A retrospective study of 33 patient's treatment results (33 eyes) with IMH was carried out. All patients underwent minimally invasive with 25G or 27G vitrectomy. Best corrected visual acuity (BCVA), macular photosensitivity, fixation stability, macular neuroepithelial (NE) volume and minimal macular hole diameter were analyzed. Follow-up period: 6 months. Results. A complete closure of the macular hole was achieved in all cases post-op. The patients had reliable improvement of BCVA, retinal photosensitivity and decrease of macular NE volume. Based on a multifactor correlation analysis with the purpose to predict the results of surgical treatment, the dependence of post-op BCVA on the pre-op photosensitivity of the retina and the minimal diameter of the macular hole was revealed. Conclusions. Microperimetry and OCT are modern non-invasive research methods allowing to estimate anatomical and functional results of surgical IMH treatment. The study of retinal photosensitivity in the macula and minimal macular hole diameter pre-op allows to predict post-op BCVA, which has a practical importance. Keywords: idiopathic macular hole, vitrectomy, microperimetry, optical coherence tomography.
