Bowen’s disease (BD) is a relatively rare in situ squamous cell carcinoma (SCC) with a limited potential of becoming invasive. Ingenol mebutate (IM) was relatively successful for the treatment of BD lesions in small case series. Optical coherence tomography (OCT) is a promising method for the diagnosis of cutaneous keratinocytic carcinomas, including BD. Herein we report the treatment of BD with the combination of cryosurgery and IM and the application of OCT imagining in treatment monitoring. Patients treated within a period of 12 months are retrospectively compiled. Treatment consisted of a mild cryosurgery session (liquid N2, open spray, and 2 freeze-thaw cycles of 15 sec each) of a field including the BD lesion and a 0.5cm rim and IM application for 4 consecutive days starting at the cryosurgery day. Four patients (3 females; average age: 76.5 years) with 4 lesions (20-70mm maximal diameter; average 36.2mm) were included. Healing was excellent and no relapse was observed at 12 months’ follow-up. Baseline OCT revealed a disarranged, thickened epidermis, while a normally layered epidermis overlying a hyperreflective dermis was present after treatment. Conclusively, the combination of cryosurgery followed by IM is a feasible, effective treatment for BD that should be evaluated in further studies.

Slow Growing

Bowen’s disease, also known as intraepithelial neoplasia, is a very slow-growing carcinoma in situ. It can progress to an invasive squamous cell cancer and infiltrate mucosa or skin in 3 to 5% of cases. The anal localization of this disease is very rare. Surgical resection is the standard of treatment. Radiotherapy keeps its place in recurrent or unresectable cases. We report a case of Bowen’s anal canal disease in order to verify the effectiveness of Radiotherapy. He is a 59-years-old patient diagnosed with Bowen’s anal canal disease at the National Institute of Oncology in Rabat. He was treated with exclusive radiotherapy at a dose of 60 Gray in 30 fractions over 49 days. The evolution was marked by a complete clinical and radiological response and preservation of the anal sphincter with an 18 months follow-up.

Background/Aims. This study evaluates changes of flow and structure of diabetic retinal neovascularization (NV) treated with intravitreal antivascular endothelial growth factor (VEGF) agents using optical coherence tomography angiography (OCTA). With OCTA, retinal blood vessels are visualized at high resolution to separately look at flow and structure information without the need for dye injection. We introduce a new measurement method including and combining information of flow and structure. Methods. Retrospective observational case series. Patients with proliferative diabetic retinopathy (PDR) were treated with intravitreal antiVEGF injections. Retinal NV were repeatedly imaged using swept-source OCTA (Zeiss PlexElite 9000) at baseline, after initial treatment block with 3-4 monthly injections, and during a follow-up period of up to 51 weeks. Change of size and flow density of the structural and angio area of NV was assessed. Results. Nine NV in eight eyes of five patients were analyzed with a median follow-up time of 45 weeks. After the initial treatment block, en face structural area regressed, 18.7% ± 39.0% (95% CI 44.2–6.8%, p = 0.26 ), and en face angio area regressed, 51.9% ± 29.5% (95% CI 32.6 to 71.2%, p = 0.007 ). Flow density within the en face structural area decreased by 33% ± 19.2% (95% CI 20.5–45.5%, p = 0.0077 ). Flow density within the en face angio area decreased by mean 17.9% ± 25.2% (95% CI 1.4–34.4%, p = 0.066 ). In two fellow eyes, NV recurrence could be observed before the onset of vitreous bleeding in one. Conclusion. Our study introduces a new quantitative measurement for NV in PDR, combining structure and flow measurement. The structure area remained after treatment, while its flow density and angio area regressed. We propose this measurement method as a more physiological and possibly more comparable metrics.

Purpose: To describe the findings of four patients (four eyes) with optic disc melanocytoma (ODM), using multimodal imaging. Methods: Retrospective case series. Results: On ocular ultrasonography ODMs appeared as hyperechogenic lesions with moderate-to-high internal reflectivity. On blue-light fundus autofluorescence, ODMs showed total hypoautofluorescence, while, on infrared reflectance images appeared as bright and well-marginated lesions. MultiColor composite images showed reddish-brown lesions with well-defined margins. Swept-source optical coherence tomography revealed elevated lesions covering the optic disc with an irregular hyperreflective surface, dishomogeneous internal structure with hyperreflective dots, and posterior shadowing. In all cases optical coherence tomography angiography detected intratumoral blood vessels which were not detectable with fluorescein angiography. Conclusion: Multimodal imaging in ODM might be useful both at presentation, increasing the diagnostic accuracy, and at follow-up, providing helpful details, that can help to rule out the possibility of malignant transformation and other ocular complications.

Chorioretinal Folds

Purpose To report 3 cases of ocular chorioretinal folds from different etiologies and their aspect with the new imaging technology of optical coherence tomography (OCT) angiography (OCT-A). Methods Baseline data, investigational process on etiology, and follow-up data of patients referred for chorioretinal folds to the Medical Retina & Imaging Unit of San Raffaele Hospital in the period January-March 2016 were collected. Multimodal imaging evaluation, comprehensive of infrared, fundus autofluorescence, multicolor, spectral-domain OCT, and OCT-A, was performed on all patients. Results Four eyes of 3 men, 65, 46, and 50 years of age, showed chorioretinal folds secondary to central serous chorioretinopathy, postoperative hypotony (after deep sclerectomy), and anisometropia with unilateral hyperopia, respectively. In all cases, OCT-A imaging showed a signal reduction in the choriocapillaris layer in correspondence of the folds. Due to this signal reduction, the en face reconstruction of choriocapillaris layer showed, in all cases, a peculiar tigroid aspect. The aspect of the folds at OCT-A remained unchanged during the 3-month follow-up in all patients. Conclusions Optical coherence tomography angiography shows a typical linear signal reduction in the choriocapillaris layer in correspondence of the fold with a tigroid pattern. We hypothesize this aspect could be explained by blood flow alteration at the choriocapillaris level in correspondence of the fold.

Introduction: To evaluate the effects of the Navilas system guided by optical coherence tomography angiography for advanced macular neovascularization (MNV) secondary to age-related macular degeneration (AMD). Methods: Prospective case-series including nine eyes presenting with advanced MNV with persistence of exudative signs, no longer responding to anti-VEGF therapy, best-corrected visual acuity at least of 1.3 logMar. All patients were treated with Navilas guided by overlaid optical coherence tomography angiography (OCTA) images at the site of branching large neovascular trunks. Results: Occlusion of large neovascular trunks successfully occurred in all nine included patients. OCTA analysis revealed, at 1 month follow up, MNV total area decreasing from 6.2 ± 3.1 to 2.6 ± 3.4 mm2. At 6 months follow up, mean MNV area was 3.3 ± 3.4 mm2 ( p = 0.008). Conclusion: This preliminary study showed that Navilas treatment guided by OCTA may represent an attractive therapeutic option in advanced neovascular lesions secondary to AMD.

Abstract Background/Objectives To re-evaluate diabetic papillopathy using optical coherence tomography (OCT) for quantitative analysis of the peripapillary retinal nerve fibre layer (pRNFL), macular ganglion cell layer (mGCL) and inner nuclear layer (mINL) thickness. Subjects/Methods In this retrospective observational case series between June 2008 and July 2019 at Moorfields Eye hospital, 24 eyes of 22 patients with diabetes and optic disc swelling with confirmed diagnosis of NAION or diabetic papillopathy by neuro-ophthalmological assessment were included for evaluation of the pRNFL, mGCL and mINL thicknesses after resolution of optic disc swelling. Results The mean age of included patients was 56.5 (standard deviation (SD) ± 14.85) years with a mean follow-up duration of 216 days. Thinning of pRNFL (mean: 66.26, SD ± 31.80 µm) and mGCL (mean volume: 0.27 mm3, SD ± 0.09) were observed in either group during follow-up, the mINL volume showed no thinning with 0.39 ± 0.05 mm3. The mean decrease in visual acuity was 4.13 (SD ± 14.27) ETDRS letters with a strong correlation between mGCL thickness and visual acuity (rho 0.74, p < 0.001). Conclusion After resolution of acute optic disc swelling, atrophy of pRNFL and mGCL became apparent in all cases of diabetic papillopathy and diabetic NAION, with preservation of mINL volumes. Analysis of OCT did not provide a clear diagnostic distinction between both entities. We suggest a diagnostic overlay with the degree of pRNFL and mGCL atrophy of prognostic relevance for poor visual acuity independent of the semantics of terminology.

Purpose: To report a series of cases showing bilateral circumpapillary hyperpigmentation on routine fundus examination. Methods: In this observational case series, three patients showing bilateral circumpapillary hyperpigmentation on routine fundus examination were included. Multimodal retinal imaging was done for these cases. Results: Multimodal imaging of the lesion showed the hyper pigmentation to be confined to the choroid. The optical coherence tomography scans described the features through the hyperpigmented area, adjacent hypopigmented area and the normally pigmented area of the fundus as suggestive of choroidal hyper melanosis. Follow-up of these lesions over a period of 2–6 years showed no change in the vision or characteristics of the lesion. Conclusion: Bilateral circumpapillary hyperpigmentation needs to be considered as a differential for bilateral peripapillary pigmented lesions.

ObjectiveTo assess anterior segment changes, including iridocorneal angle and vault, after toric and non-toric implantable collamer lens (ICL) V4c (STAAR Surgical AG) implantation under different lighting conditions.MethodsLongitudinal, prospective, case series. Patients with high myopia (>6 dioptres) underwent toric and non-toric ICL V4c implantation. Optical coherence tomography measurements were taken under different lighting conditions preoperatively and at 1 week and 1, 6 and 12 months of follow-up.ResultsSeventy-six eyes of 42 patients underwent ICL V4c implantation. Mean age was 27.4 years (±5.14 years, range 20 to 39 years). The average iridocorneal angle showed a statistically significant decrease (p<0.05) in all mesopic, scotopic and photopic conditions after 1 week of surgery compared with the preoperative measurements; in mesopic conditions, it decreased 14.1°, in photopic conditions 14.8° and scotopic conditions 13.2°. The angle measurement had a statistically significant change only in mesopic conditions (p=0.01) over the 1-year follow-up. The average vault under mesopic conditions was 0.661±0.21 mm at week 1. The vault measurement change was statistically significant over the 1-year follow-up in mesopic conditions (p=0.01). Refractive results showed a significant improvement in both uncorrected and corrected distance visual acuity (p<0.001).ConclusionThere is a significant reduction in the iridocorneal angle after ICL V4c implantation. Furthermore, there is a change under mesopic conditions in both the iridocorneal angle and vault during long-term follow-up.
