Ocriplasmin is a protease which has been approved for the treatment of symptomatic vitreomacular adhesion (VMA). A 63-year-old presented with blurred vision in the left eye and a best corrected visual acuity of 6/18. Optical coherence tomography revealed VMA with an underlying macular hole and she subsequently underwent a left intravitreal ocriplasmin injection. One week after the injection, VMA had been released but with enlargement of the macular hole and a drop in her BCVA to 6/60. This persisted at 1 month after the injection. It is important to warn patients that ocriplasmin may lead to an enlargement of their macular hole with resultant loss in visual acuity.

Purpose: We report a case of a foveal macroaneurysm with long-standing macular edema in a rare location, successfully treated with intravitreal ranibizumab. Methods: We report the case of a 52-year-old man with left eye long-term visual loss due to macular edema caused by a retinal macroaneurysm, localized about 400 μm from the center of the fovea, and its response to 6 monthly ranibizumab intravitreal injections. His best-corrected visual acuity and morphological data evaluated by optical coherence tomography and fluorescein angiography are presented. Results: His best-corrected visual acuity improved from 1/10 to 3/10 after the 3rd injection, and from 1/10 to 4/10 after the 6th one. The central retinal thickness was evaluated by optical coherence tomography and improved from 310 to 233 μm, with the resolution of both the associated serous detachments and the cystoid macular edema; an almost complete reabsorption of the hard exudates at the end of the treatment was also observed. The macroaneurysm lumen almost obliterated after the 3rd injection and completely collapsed at the end of treatment. Conclusions: Intravitreal ranibizumab may be effective in the treatment of long-standing macular edema associated with foveal macroaneurysms. To the best of our knowledge, this is the first report of a retinal macroaneurysm located so close to the foveal avascular zone.

Purpose: To report a case of Purtscher-like retinopathy due to atypical hemolytic uremic syndrome and the changes seen in the optical coherence tomography angiography before and after treatment with eculizumab. Case description: A 22-year-old man with an unremarkable medical history presented with acute, bilateral blurred vision and headache of 1-week duration. Best corrected visual acuity of 20/50 and 20/40, respectively, in the patient’s right eye and left eye. Funduscopy revealed multiple cotton-wool spots associated with intrarretinal fluid. Swept source optical coherence tomography revealed multifocal retinal detachments with increased choroidal thickness. Optical coherence tomography angiography showed areas of ischemia in both capillary plexus. Due to concurrent symptoms and laboratory analysis, he was diagnosed with atypical hemolytic uremic syndrome and secondary Purtscher-like retinopathy; therefore, treatment with eculizumab was initiated. After 2 months revascularization of the previous ischemic areas was seen in the optical coherence tomography angiography that were correlated with best corrected visual acuity improvement. Conclusion: Our findings suggest that evaluation of the macular capillary plexus revascularization by optical coherence tomography angiography during the disease could help to predict an improvement of best corrected visual acuity in these patients and the measurement of choroidal thickness could give us information about the resolution of the pathologic process.

Importance: To provide new insights into aflibercept effect in non-naive-treated patients with neovascular age-related macular degeneration. Purpose: To assess the efficacy of intravitreal aflibercept in patients with neovascular age-related macular degeneration without optimal response to previous anti-vascular endothelial growth factor A therapy. Design: Single-arm, multi-centre, prospective study. Participants: Patients ⩾50 years with active neovascular age-related macular degeneration, best-corrected visual acuity between 20/32 and 20/320 with suboptimal response to ranibizumab or bevacizumab. Methods: Aflibercept was administered monthly (3-first months), and bimonthly thereafter until month 8. Anatomical and functional outcomes were assessed. Main outcome measure: Percentage of eyes without intra or subretinal fluid on optical coherence tomography after 3-monthly loading doses of aflibercept. Results: A total of 46 patients were included. At week 12, 45.7% (95% confidence interval: 31.5%–60.1%) of eyes showed no fluid on optical coherence tomography. The mean (standard deviation) best-corrected visual acuity increased from 65.1 (8.3) to 69.6 (8.1) letters (+4.5 (5.8) p < 0.0001) and was stabilized at week 40 as compared to baseline. Mean central macular thickness decreased from 430 (119) µm to 323 (100) µm at week 12 (–107 (90) µm, p < 0.0001) and was reduced at week 40 (–46 (111) µm, p = 0.0056). At week 40, 21.7% (95% confidence interval: 9.8%–33.7%) had no fluid. There was a case of presumed noninfectious endophthalmitis that was successfully managed. Conclusion: Almost half of patients presented no fluid on optical coherence tomography at week 12, and there was a clinically significant improvement in best-corrected visual acuity. At week 40, one in five patients did not show intra or subretinal fluid, central macular thickness decreased and best-corrected visual acuity was stabilized compared to baseline.

Background: Patients with congenital aniridia usually have some degree of foveal hypoplasia, thus representing a limiting factor in the final visual acuity achieved by these patients. The purpose of this study was to analyze whether the foveal morphology assessed by spectral-domain optical coherence tomography may serve as a prognostic indicator for best-corrected visual acuity in congenital aniridia patients. Methods: Observational two-center study performed between January 2012 and March 2017 in the pediatric ophthalmology department at Vissum Alicante and Vissum Madrid, Spain. A total of 31 eyes from 19 patients with congenital aniridia were included. After a complete ophthalmological examination, a high-resolution spectral-domain optical coherence tomography with a three-dimensional scan program macular protocol was used. A morphological grading system of foveal hypoplasia was used varying from grade 1 in which there is a presence of a shallow foveal pit, extrusion of inner retinal layers, outer nuclear layer widening, and a presence of outer segment lengthening to grade 4 in which none of these processes occur. Results: No correlation between central, mid-peripheral, and peripheral macular thickness and logMAR best-corrected visual acuity was found. The presence of outer segment lengthening was associated with better best-corrected visual acuity with a median best-corrected visual acuity, 0.30 logMAR, whereas the absence of this morphologic feature was associated with poorer VA with a median best-corrected visual acuity of 0.61 logMAR (p < 0.001). Conclusion: Foveal hypoplasia morphology can predict the best-corrected visual acuity. Specifically, the morphologic optical coherence tomography feature that is related to a better best-corrected visual acuity in congenital aniridia patients is the presence of outer segment lengthening.

Purpose: To describe the optical coherence tomography angiography characteristics of myopic patients with choroidal neovascularization secondary to pathologic myopia during ranibizumab therapy. Methods: Nineteen patients were enrolled in this prospective study (13 females, 6 males, mean age 55.25 ± 9.63 years) for a total of 20 eyes examined (14 right eyes, 6 left eyes). Images were analyzed independently by two examiners. Results: Mean follow-up was 5.75 ± 1.88 months, with a mean intravitreal injections of 1.90 ± 0.44. Mean best-corrected visual acuity at baseline was 0.39 ± 0.18 logMAR versus 0.26 ± 0.16 logMAR 6 months after treatment. The neovascular area (Z = –2.091, p = 0.037) was significantly reduced after treatment, whereas vessel density was not (Z = –1.848, p = 0.065). Moreover, the best-corrected visual acuity was increased (Z = –3.055, p = 0.002). Neovascular area was significantly correlated with best-corrected visual acuity, at both baseline and follow-up (p < 0.05). Conclusion: Our data suggest that optical coherence tomography angiography is a reproducible non-invasive examination with which to monitor changes in the neovascular area in patients with pathologic myopia treated with ranibizumab.

Purpose: To describe the clinical features and surgical outcomes of diabetic retinopathy–associated lamellar macular hole and compare them with those of idiopathic lamellar macular hole. Methods: A total of 17 eyes with diabetic retinopathy–associated lamellar macular hole and 30 eyes with idiopathic lamellar macular hole undergoing surgery were retrospectively enrolled. Baseline best-corrected visual acuity, preoperative optical coherence tomography characteristics, and final best-corrected visual acuity were compared between two groups. Results: Both the baseline and the final best-corrected visual acuity in the diabetic retinopathy group were significantly worse than those in the idiopathic group (p = 0.029 for baseline, p = 0.002 for final). Lamellar macular hole in diabetic retinopathy tended to have a wider opening (p < 0.001) and a thinner residual base (p = 0.023). The width and height of parafoveal schisis in diabetic retinopathy–associated lamellar macular hole were both larger than those in idiopathic lamellar macular hole (p < 0.001 for both). After operation, both groups achieved significant improvement in best-corrected visual acuity (p < 0.01 for both). Conclusion: Compared with idiopathic group, diabetic retinopathy–associated lamellar macular hole had worse baseline best-corrected visual acuity, wider defect, and more pronounced parafoveal schisis. However, significant visual improvement could be obtained after operation. All cases in both groups achieved good anatomical outcomes with normalization of foveal contour and reduction of parafoveal schisis.

Background: To evaluate intravitreal injection of expansile sulfur hexafluoride (SF6) as a low cost and effective treatment for symptomatic vitreomacular adhesion (sVMA). Methods: Retrospective analysis of all patients with sVMA treated with pneumatic vitreolysis using SF6 gas presenting to a clinical practice from January 2005 and June 2013. Results: Six cases were included in the study. Five patients (83%) experienced complete resolution of the vitreomacular adhesion. One patient had a partial release of the vitreomacular adhesion. Four patients (67%) had a one line improvement in best corrected visual acuity. Conclusion: Due to its low cost, wide availability, and apparent efficacy, intravitreal injection of expansile SF6 should be investigated further as a possible treatment modality for sVMA.

Background: to study the correlation of mean macular thickness using optical coherence tomography with distant and near visual acuity in patients of diabetic maculopathy.Methods: A prospective, single centre study was conducted on 50 eyes of diabetic patients, with Diabetic Retinopathy with CSME in which patients macular thickness was measured on Ocular Coherence Tomography using fast macular thickness scan. The unaided and best corrected visual acuity was measured in all patients using Snellens distant vision and Jaggers near vision charts.Results: A linear correlation between the OCT measured macular thickness and both the distance visual acuity and the near visual acuity. That means that for a given level of macular thickness, we can predict visual acuity for it. In our series correlation coefficient was 0.921 for distance visual acuity and 0.899 for near visual acuity. Although the correlation value is high in our study, we did find a range of visual acuities for a given range of macular thickness. For every 100 micron change in mean macular thickness, best corrected visual acuity (BCVA) changed 0.3 LogMAR units, for distance as well as for near.Conclusions: Macular thickness and visual acuities (distance as well as near) are strongly correlated but there can be variations. And a wide range of visual acuities is possible for a given degree of macular edema. Macular thickness though a strong predictor of visual acuity; other factors might also play a role in determining visual acuity for a particular patient.
