RESUMEN

Objective: Progressive retinal atrophy has been described after subretinal gene therapy utilizing the adeno-associated virus (AAV) vector platform. To elucidate whether this atrophy is a consequence of inherent properties of AAV, or if it is related to the surgical trauma of subretinal delivery, we analyzed data from an Investigational New Drug-enabling study for PDE6A gene therapy in nonhuman primates. Design: Animal study (nonhuman primates), retrospective data analysis. Subjects: Forty eyes of 30 healthy nonhuman primates (macaca fascicularis) were included in the analysis. Two AAV dose levels (low: 1x10E11, high: 1x10E12) were compared with sham injection (balanced saline solution; BSS). Twenty untreated eyes were not analyzed. Methods: Animals were treated with a sutureless 23G vitrectomy and single subretinal injections of AAV.PDE6A and/or BSS. The follow-up period was 12 weeks. Atrophy development was followed using fundus autofluorescence (AF), OCT, fluorescence angiography, and indocyanine green angiography. Main Outcome Measures: Area [mm2] of retinal pigment epithelium atrophy on AF. Presence of outer retinal atrophy on optical coherence tomography. Area [mm2] of hyperfluorescence in fluorescence angiography and hypofluorescence in indocyanine green angiography. Results: Progressive atrophy at the injection site developed in 54% of high-dose-treated, 27% of low-dose-treated, and 0% of sham-treated eyes. At the end of observation, the mean ± SD area of atrophy in AF was 1.19 ± 1.75 mm2, 0.25 ± 0.50 mm2, and 0.0 ± 0.0 mm2, respectively (sham × high dose: P = 0.01). Atrophic lesions in AF (P = 0.01) and fluorescence angiography (P = 0.02) were significantly larger in high-dose-treated eyes, compared with sham-treated eyes. Rate of progression in high-dose-treated eyes was 4.1× higher compared with low-dose-treated eyes. Conclusion: Subretinal injection of AAV.PDE6A induced dose-dependent, progressive retinal atrophy at the site of injection. Findings from multimodal imaging were in line with focal, transient inflammation within the retina and choroid and secondary atrophy. Atrophic changes after gene therapy with AAV-based vector systems are not primarily due to surgical trauma and increase with the dose given.

RESUMEN

PURPOSE: Spontaneous closure of idiopathic full-thickness macular holes (iFTMH) has been reported regularly. However, little is known about its probability and timeline. METHODS: In this retrospective study all consecutive patients who presented between August 2008 and August 2019 were screened for the presence of a macular hole and only iFTMHs were included. The primary outcome measure was the spontaneous closure of the iFTMH. RESULTS: Of 1256 eyes with macular holes, 338 fulfilled the inclusion criteria. Spontaneous closure of the iFTMH was detected in 31 eyes (9.2%) with a median time of 44 days after diagnosis. Eyes exhibiting spontaneous closure demonstrated a higher baseline best-corrected visual-acuity (BCVA) and smaller iFTMH diameter (p < 0.0001 and p < 0.0001, respectively). The mean BCVA improved from 0.4 logMAR (SD ± 0.21) to 0.29 logMAR (SD ± 0.20) after spontaneous closure (p = 0.031). The iFTMH diameter was positively correlated with the time to spontaneous closure (Pearson-r = 0.37, p = 0.0377). Spontaneously closed iFTMHs reopened in 16% (n = 5) of cases, with a median of 136 days after closure. A logistic regression model showed the hole diameter was associated with spontaneous closure (odds-Ratio 0.97, 95%CI [0.96, 0.98]). The Kaplan-Meier-Curve revealed that approximately 25% of small-iFTMH (n = 124) and 55% of iFTMH with a diameter < 150µm (n = 48) closed spontaneously within two months. CONCLUSION: The established gold-standard for the treatment of iFTMHs is macular surgery. However, the potential for spontaneous closure of small iFTMHs must be acknowledged. Therefore, if surgical treatment is delayed in individual cases, close observation is recommended.

RESUMEN

This study aimed to automatically detect epiretinal membranes (ERM) in various OCT-scans of the central and paracentral macula region and classify them by size using deep-neural-networks (DNNs). To this end, 11,061 OCT-images were included and graded according to the presence of an ERM and its size (small 100-1000 µm, large > 1000 µm). The data set was divided into training, validation and test sets (75%, 10%, 15% of the data, respectively). An ensemble of DNNs was trained and saliency maps were generated using Guided-Backprob. OCT-scans were also transformed into a one-dimensional-value using t-SNE analysis. The DNNs' receiver-operating-characteristics on the test set showed a high performance for no-ERM, small-ERM and large-ERM cases (AUC: 0.99, 0.92, 0.99, respectively; 3-way accuracy: 89%), with small-ERMs being the most difficult ones to detect. t-SNE analysis sorted cases by size and, in particular, revealed increased classification uncertainty at the transitions between groups. Saliency maps reliably highlighted ERM, regardless of the presence of other OCT features (i.e. retinal-thickening, intraretinal pseudo-cysts, epiretinal-proliferation) and entities such as ERM-retinoschisis, macular-pseudohole and lamellar-macular-hole. This study showed therefore that DNNs can reliably detect and grade ERMs according to their size not only in the fovea but also in the paracentral region. This is also achieved in cases of hard-to-detect, small-ERMs. In addition, the generated saliency maps can be used to highlight small-ERMs that might otherwise be missed. The proposed model could be used for screening-programs or decision-support-systems in the future.

RESUMEN

The choroid plays an important role in the pathophysiology of the eye. Multimodal imaging offers different techniques to examine the choroid. Fundus fluorescein angiography offers limited visualization of the deep layers of the fundus due to the barrier property of the retinal pigment epithelium. Therefore, indocyanine green angiography (ICGA) is widely used in the angiographic examination of the choroidal structure. ICGA is an important component of multimodal imaging in the diagnosis and treatment of many degenerative, tumoral, and inflammatory diseases of the choroid and retina. This review presents the general characteristics of ICGA and a practical approach to its clinical use.

RESUMEN

PURPOSE: To analyze torpedo maculopathy (TM) and to report the characteristics of the disease. METHODS: Retrospective study. The review of a database for clinical diagnosis identified eight patients with TM lesions in the retina between 2016 and 2022. Multimodal imaging was used to analyze the cases. RESULTS: All cases were unilateral, asymptomatic, and hypopigmented. They were associated by surrounding hyperpigmented retinal pigment epithelium changes to varying degrees. All lesions were located in the temporal retina on the horizontal axis, pointing towards the fovea, except for one patient with a lesion inferior to the fovea. Optical coherence tomography imaging revealed a normal inner retina in all eyes. In the area of the TM lesion, attenuation of the interdigitation zone was seen in mild cases (three cases). All other five patients had thinning of the outer nuclear layer and loss of ellipsoid zone and interdigitation zone of the TM lesion. Four of these cases had a subretinal cavitation/cleft, and two of them additionally an inner choroidal excavation. No patient had any sign of choroidal neovascularization. The average age for patients with type 1 TM was 18 years and for type 2 TM 16.5 years. CONCLUSION: In this large case series, we could not detect an age difference between the different types of the TM. Contrary to previous discussions, type 2 TM can also occur in young patients.

RESUMEN

PURPOSE: To investigate the clinical characteristics of fall-related ocular trauma in patients over 90 years of age. METHODS: Retrospective, medical record reviews. Patients over the age of 90 years treated in a tertiary center with fall-related ocular trauma were included in the study. RESULTS: Fifty consecutive patients (fifty eyes) were analyzed. The mean age was 93.6 ± 1.8 years and 41 patients (82%) were female. The most common site of the injuries was orbital fracture (18 patients, 36%), accompanied with open globe rupture (OGR) in three patients, and globe contusion in two patients. Seventeen patients (34%) presented with OGR. Ocular trauma score in those patients was category 1 in 10 patients (58.8%) and category 2 in the others. Conjunctival hemorrhage and/or periocular contusion was seen in 14 patients (28%) and globe contusion in six patients (12%). At the presentation, the mean best corrected visual acuity (BCVA) was 2.82 ± 0.24 logMAR in patients with OGR and 1.98 ± 0.81 logMAR in six patients with globe contusion. Three of the patients with OGR had a final vision of 20/200 or better whereas the remaining patients had hand movements or less. The most common risk factors were female gender (82%) and use of antihypertensive drugs (46%). CONCLUSION: Patients with OGR had a poor visual outcome despite the early treatment. It is important to raise public awareness about of the poor prognosis of ocular injuries due to falls in the elderly population in order to establish preventive measures.

RESUMEN

BACKGROUND: To investigate the cavity of lamellar macular holes (LMH-CV) by using volumetric analysis of optical coherence tomography images. METHODS: Single-center, retrospective, observational case series. The volume of the LMH-CV and epiretinal proliferation was determined. Best-corrected visual acuity, central macular thickness, maximum horizontal diameter and minimum horizontal diameter, and the presence of foveal bump and ellipsoid zone defect were noted. RESULTS: Forty-nine eyes of 46 patients (20 women) were included in the baseline analysis. The natural course group consisted of 25 patients (27 eyes) with a mean follow-up of 19.2 ± 15.7 months. The volume of LMH-CV was found to be a predictive factor for baseline best-corrected visual acuity (P = 0.038, ß-coefficient = 0.338, 95% CI: 0.275-8.893). Whereas no significant change at the last visit was observed in central macular thickness, minimum horizontal diameter, and maximum horizontal diameter, the LMH-CV and epiretinal proliferation volume increased significantly (P = 0.036, P < 0.001, respectively). Eyes with foveal bump had larger minimum horizontal diameter, maximum horizontal diameter, and LMH-CV volume (P = 0.008, P < 0.001, P = 0.024, respectively). Eyes with ellipsoid zone defect showed larger LMH-CV and epiretinal proliferation volume, but thinner central macular thickness (P = 0.038, P = 0.004, P = 0.012, respectively). CONCLUSION: Volumetric analysis of LMH-CV detects changes in the natural course of lamellar macular hole earlier than the measurement of horizontal diameters. Further studies will clarify whether volumetric analysis of the lamellar macular hole is useful as an additional biomarker in the management of lamellar macular hole.

RESUMEN

PURPOSE: To analyse the clinical and morphological characteristics of eyes with idiopathic epiretinal membrane (iERM) and foveal herniation (FH). METHODS: Clinical findings and OCT features of patients with iERM and FH were retrospectively analysed. Primary outcome were changes of the best-corrected-visual-acuity (BCVA) and OCT features from baseline to the last visit. FH patients were divided into two groups based on herniated layers: ganglion cell complex (GCC)-group and sub-GCC-group. Surgical outcome was also assessed. RESULTS: In this study, 3882 patients with iERM were screened, of whom 51 (1.3%) were identified with FH. The GCC-group (n = 16) had a better baseline BCVA and thinner central foveal thickness (CFT) in comparison to the sub-GCC-group (n = 35) but without statistical significance (p = 0.330, p = 0.417, respectively). The postoperative BCVA-improvement was similar between the two groups (p = 0.280). Fibrillary surface changes were detected in 42/51 (82.3%) patients, significantly more often in the sub-GCC group (p = 0.020). The baseline BCVA was a predictive factor for the postoperative vision change. CONCLUSION: FH presents with a unique macular morphology in eyes with iERM. Affected eyes experience varying visual disturbances based on the involvement of the inner retinal layers in the foveal herniation. Macular surgery is successful in restoring vision, even though foveal morphology does not fully recover.

RESUMEN

PURPOSE: The purpose of this study is to investigate the clinical and morphological characteristics of epiretinal membrane (ERM)-Foveoschisis. METHODS: Medical charts of 2088 patients diagnosed with idiopathic ERM were screened and eyes with ERM-Foveoschisis were included. All eyes underwent a complete ophthalmological examination including spectral domain optical coherence tomography (SD-OCT). OCT features and best corrected visual acuity (BCVA) were analysed. ERM-Foveoschisis was defined as open, closed, elevated or flat based on the OCT features. Ellipsoidal zone (EZ) abnormality, intraretinal cystoid spaces, central foveal thickness (CFT), posterior vitreous detachment (PVD) and lens status were assessed. RESULTS: One hundred-sixty-six patients (175 eyes) (72% female, mean age 70.46 years) were included. Incidence of ERM-Foveoschisis was 6.7%. Open type was seen in 86.8% and had a significantly better mean BCVA than closed type (p = 0.01). No statistically significant difference of mean BCVA was noted between the elevated and flat types. Mean BCVA was significantly lower in eyes with EZ abnormality (p = 0.03) and eyes with intraretinal cystoid spaces (p = 0.02). Patients with 'closed' ERM-Foveoschisis showed a significant higher median CFT than 'open' ERM-Foveoschisis (respectively, 364 µm and 176 µm, p < 0.001). A total of 81.9% eyes had PVD. CONCLUSION: We differentiated four morphological types of ERM-Foveoschisis based on the OCT examination. Closed ERM-Foveoschisis presented with a higher CFT and lower BCVA than the open type. ERM-Foveoschisis with cystoid intraretinal spaces presented with a lower BCVA. The impact of the morphological types of the ERM-Foveoschisis on the clinical course and for therapy decision requires further long-term studies.

RESUMEN

PURPOSE: The aim of this study was to analyze the impact of OCT characteristics on the natural course of optic disc pit maculopathy (ODP-M). METHODS: This was a single-center, retrospective, observational case series. Patients with ODP-M were included in the study. Baseline demographic characteristics, central macular thickness (CMT), IPP, subretinal fluid (SRF), subretinal precipitations, outer retinal fluid (ORF), and outer retinal layer hole were evaluated. The changes in the OCT characteristics were analyzed with respect to the best-corrected visual acuity (BCVA) from baseline to the last visit. RESULTS: Twenty-two eyes of 22 patients were evaluated with a mean follow-up time of 37.6 (median 22) months. The mean BCVA was 0.31 logMAR at baseline and 0.28 logMAR at the final visit (p = 0.521). Baseline BCVA was significantly related to CMT (ß coefficient 0.001, p = 0.002). Mean BCVA increased in 7 patients (group 1), remained stable in nine (group 2), and decreased (group 3) in 6 patients. No significant difference was found between the groups regarding the baseline BCVA, CMT, and extent of retinal fluid. In patients with subretinal deposits, BCVA remained stable in 3 patients and worsened in one. ORF was recorded in all patients. In patients with SRF, the mean change of BCVA during follow-up differed significantly, depending on the presence (0.07 logMAR) or absence (-0.125 logMAR) of SRF (p = 0.019). CONCLUSION: Among the OCT characteristics, SRF was a negative prognostic factor in ODP-M. Most ODP-M patients showed improved or stable vision over 3 years of follow-up. Therefore, observation may be considered in patients with reasonable vision and without SRF even when they present with remarkable OCT findings.

RESUMEN

AIM: To evaluate the impact of the optical coherence tomography (OCT) scan patterns on the detection of the features associated with lamellar macular hole (LMH) and macular pseudohole (MPH). METHODS: This is a retrospective analysis of 100 consecutive eyes with LMH (n=41) and MPH (n=59) having at least three of the following OCT features, which include mandatory criteria for the diagnosis of LMH and MPH: Epiretinal membrane, epiretinal proliferation, verticalization, intraretinal cystoid spaces, foveoschisis, irregular foveal contour, foveal cavity with undermined edges, and ellipsoid line disruption. Primary outcome measurement was the detection frequency of the features in three different OCT scan patterns: 1) volume scan; 2) six radial scans (R6); and 3) vertical and horizontal radial scans (R2). RESULTS: Of the total eight features, the maximal detection frequency was found as 4.45±1.45, 4.35±1.47, and 3.70±1.59, by the volume, R6 and R2, respectively. R2 was inferior to the other patterns in detection of the total features (P<0.001), whereas R6 and volume patterns were found comparable (P=0.312). CONCLUSION: The physician should be aware that the selection of the OCT-scan pattern may influence the detection of mandatory morphological criteria for the diagnosis of LMH and MPH.

RESUMEN

PURPOSE: To better assess clinical trajectories of patients with or without ocular comorbidity after Descemet membrane endothelial keratoplasty. BACKGROUND: To report on the outcomes of eyes with differing starting conditions following surgery. DESIGN: Retrospective study at a University Eye Hospital. PARTICIPANTS: 361 eyes separated into group 1 (n=229; eyes with endothelial disease only) and group 2 (n=132; eyes with additional ocular comorbid conditions, such as herpetic eye disease 18/132 (13.6%), glaucoma 16/132 (12.1%), dry age-related macular degeneration 14/132 (10.6%), epiretinal membranes 10/132 (7.6%), and wet age-related macular degeneration 9/132 (6.8%)). METHODS: Consecutive eyes that underwent Descemet membrane endothelial keratoplasty over a follow-up period of up to 7 years at a tertiary referral center were reviewed. Main outcome measures were best-corrected visual acuity, postoperative complications, graft survival, central corneal thickness, and endothelial cell density. RESULTS: Postoperative best-corrected visual acuity at year 1 improved in both groups significantly (Wilcoxon signed rank test: group 1, p =.002; .63 to .23 logMAR; group 2, p <.001; 1.15 to .87 logMAR) with a group difference in favor of group 1 (p =.009, Mann-Whitney-Wilcoxon). A decrease of the endothelial cell density and central corneal thickness was noted at postoperative year 1 for both groups (paired t-tests (group 1, p <.001; group 2, p =.045) and paired t-tests (group 1, p <.001; group 2, p =.003). Complications were less common, and graft longevity was superior in group 1. CONCLUSION: Eyes with different starting conditions might experience a visual improvement and benefit from surgery. Descemet membrane endothelial keratoplasty is a valid treatment for endothelial disorders in manifold of eyes. Further long-term studies are required.

RESUMEN

We report a case of posterior uveal effusion (UE) with a long-term follow-up that has occurred following cataract surgery. A 64-year-old woman presented with diminished vision of the right eye (RE) 3 weeks after an uneventful phacoemulsification and intraocular lens implantation. Complete ophthalmic examination including fluorescein angiography (FA), indocyanine green angiography (ICGA), echography and optical coherence tomography (OCT) were performed. Best corrected visual acuity (BCVA) of the RE was 20/50. Anterior segment and intraocular pressure were unremarkable. OCT revealed prominent folds of the choroid and retina, subretinal fluid and darkening of the choroid with reduced visibility of the choroidal vessels and the scleral border. The left eye (LE) was unremarkable. BCVA of the LE was: 20/20. After topical anti-inflammatory and systemic corticosteroid therapy for 5 months, no morphological change of the macula was seen. The patient was observed without any treatment. Forty-three months after the cataract surgery and 38 months after cessation of the corticosteroid therapy, OCT revealed a normal macular morphology and the BCVA improved to 20/25. Even though rare, UE at the posterior pole may occur after modern cataract surgery. OCT examination is a reliable tool in monitoring the macular morphology. Since morphological and functional improvement can be seen in long-term, observation may be considered for some cases of posterior UE with resistance to the therapy.

RESUMEN

Introduction: To analyze foveal displacement after macular surgery for idiopathic epiretinal membrane (iERM). Methods: Twenty-eight patients who underwent macular surgery for symptomatic iERM in one eye by one physician were included in this retrospective study. Spectral domain optical coherence tomography (SD-OCT) volume scans were acquired with a Spectralis OCT device (Heidelberg Spectralis). Using the follow-up view mode, the displacement of the fovea was classified and measured according to its postoperative location in the horizontal and/or vertical plane. Results: One day after surgery, 86% of eyes (24/28) showed foveal displacement. Vertical displacement occurred in a superior direction in 50% eyes, and in an inferior direction in 36% of the eyes. The postoperative mean foveal displacement on the vertical plane was 99 ± 82 µm (range, 0-300). Horizontal displacement occurred in a nasal direction in 21%, and temporally in 21%. The postoperative mean foveal displacement on the horizontal plane was 35 ± 45 µm (range, 0-123). One year after the macular surgery 69% of the eyes showed still a foveal dislocation. Discussion: Most of the eyes with iERM showed a foveal dislocation after the macular surgery. Our findings emphasize the necessity to carefully study of the OCT images in such eyes after the surgery as the manually determined postoperative foveal position may be in a different vertical or horizontal plane than the machine-generated pre- and postoperative overlay for the foveal position. Our findings may thus be helpful for surgeons to avoid misinterpretation when evaluating OCT images pre- and postoperatively.

RESUMEN

PURPOSE: To assess the developments in contrast sensitivity, color vision, and subjective perception after Descemet membrane endothelial keratoplasty (DMEK) in patients with Fuchs endothelial corneal dystrophy (FECD). METHODS: Included in this study were pseudophakic, unilateral DMEK patients with bilateral FECD having a follow-up period of 6 months (n = 23). The mean age at surgery was 70 years (range: 52-81 years). Pseudophakic eyes without history of other ocular pathology or surgery served as a control (n = 10). Pelli-Robson contrast sensitivity and Panel-D15 color vision tests were used. Best-corrected visual acuity, modified visual functioning questionnaire-25, central corneal thickness, and endothelial cell density were assessed. We visualized the subjective impression of patients with bilateral FECD after unilateral DMEK in a subgroup using Photoshop CS6. RESULTS: Contrast sensitivity improved significantly from 1.35 ± 0.26 to 1.64 ± 0.17 (P = 0.002; control eyes: 1.92 ± 0.09). No difference in the color vision error score was observed for preoperative and postoperative eyes (P = 0.063). The best-corrected visual acuity improved significantly after surgery (P = 0.001). The average values in the Logarithm of the Minimum Angle of Resolution were 0.59 ± 0.42 preoperatively and 0.1 ± 0.10 postoperatively (control eyes: 0.01 ± 0.03). Examinations revealed a decrease of the central corneal thickness and endothelial cell density after surgery (P = 0.001; P = 0.001, respectively). Scores in the general and the driving questionnaire were significantly higher after surgery (P = 0.001; P = 0.005, respectively). CONCLUSIONS: This study showed significant improvement in subjective patient satisfaction and contrast sensitivity. Spontaneous subjective color vision improvement might be explained by significantly improved contrast sensitivity. Contrast sensitivity might be considered as a parameter in preoperative decision-making and evaluation of surgical outcome.

RESUMEN

INTRODUCTION: The aim of this article was to report on a rebound phenomenon after intravitreal triamcinolone acetonide (IVTA) injection for macular edema secondary to diabetic retinopathy (DR) and central or branch retinal vein occlusion (CRVO/BRVO). METHODS: The data were analyzed retrospectively. Complete ophthalmic examinations, including spectral domain optical coherence tomography, were performed before and 2 months after IVTA injection. The incidence of a rebound phenomenon was defined as an increase in central retinal thickness of >10% from baseline at 2 months after IVTA injection. RESULTS: This retrospective study included 211 consecutive patients (268 eyes). One hundred ninety (71.2%), 39 (14.6%), and 39 (14.6%) eyes had macular edema (ME) due to DR, CRVO, and BRVO. In total, 9.7% of the eyes showed a rebound phenomenon (DR: 9.5%, CRVO: 5.2%, BRVO: 15.4%). The mean number of prior injections of vascular endothelial growth factor inhibitor or corticosteroid agent was statistically significantly higher in the rebound group (6.8 vs. 5.3) than in the nonrebound group (p = 0.01). CONCLUSION: Our study shows that 9.7% of the eyes with ME secondary to DR and RVO developed a rebound phenomenon following IVTA injection, limiting its therapeutic effect. We found an increased number of prior intravitreal pharmacotherapy to be a risk factor for a rebound phenomenon.

RESUMEN

A 28-year-old female patient presented with acute loss of visual acuity after pre-eclampsia. Funduscopy revealed minor alterations of the posterior pole of the macula. Optical coherence tomography displayed a bilateral neurosensory detachment. Fluorescence angiography showed filling defects of the choroid in both eyes. These findings were in line with choroidal ischemia following a hypertensive episode. The symptoms disappeared completely after 3 months without additional treatment. To clarify ambiguous pathologies the ophthalmologist should always initiate a comprehensive evaluation in internal medicine to find the right diagnosis and treatment.

RESUMEN

PURPOSE: To report a case of acute choroidopathy following a blunt ocular trauma. METHODS: Ocular examination included dilated fundus examination and optical coherence tomography enhanced depth imaging (OCT-EDI). PATIENTS: Single-patient case report. CASE REPORT: A 10-year-old boy was referred following a blunt trauma to the right eye. The visual acuity diminished to 20/200 and mild hemorrhage was found in the anterior chamber. The fundoscopy was unremarkable. An OCT-EDI revealed a choroidal thickening and detachment at the macula. Six month later, the choroidal morphology resolved and the visual acuity improved. CONCLUSIONS: This study reported a case of acute choroidopathy associated with temporary thickening of the choroid and separation of the Haller's layer from the sclera. OCT-EDI helped to detect and monitor the morphological changes in the apparently normal-looking macular choroid after ocular trauma. Further case reports with long term follow-up are needed to clarify the clinical impact of posttraumatic acute choroidopathy.
