Objectives To evaluate the outcomes of strabismus surgery in patients with thyroid eye disease (TED) and to assess the influence of preceding treatments such as steroid administration, orbital decompression and radiotherapy. Methods Retrospective study on a cohort of patients with TED undergoing strabismus surgery. Data collection included clinical features, smoking status, preceding steroid therapy, orbital radiation therapy and orbital decompression. Qualitative evaluation, assessing diplopia and quality of life and quantitative evaluation, assessing the eye misalignment were analysed 1 year after the last squint surgical procedure. Results Seventy-nine patients were identified. Ninety-five surgical procedures were performed on 92 eyes. A significant overall improvement of ocular motility was registered ( p Conclusion Strabismus surgery in TED patients resulted in a high success rate in reducing diplopia and improving ocular motility. The success rate was not negatively associated with previous therapies. Indeed, resolution of diplopia required more squint procedures in patients who have previously undergone to orbital decompression.

Purpose To quantitatively investigate the role of deep capillary plexus (DCP) in patients affected by type 3 macular neovascularization (MNV), compared to patients with reticular pseudodrusen (RPD) eyes and healthy controls, using optical coherence tomography angiography (OCTA). Methods In this prospective observational study, a total of seventy-eight eyes of 78 patients were included. Group 1 consisted of 40 eyes of 40 patients with stage 1 of type 3 MNV (22 males, 18 females, mean age 73.7, SD ± 6.60) and group 2 included 38 eyes of 38 patients with RPD (17 males, 21 females, mean age 73.2, SD ± 4.55). The control group included 40 eyes of 40 healthy subjects (20 males, 20 females, mean age 71.4, SD ± 6.36 years). We evaluated the retinal vessel density (VD) of superficial capillary plexus (SCP) and deep capillary plexus (DCP) using OCTA. Results Patients with diagnosis of type 3 MNV showed statistically lower values of VD in DCP with respect to controls and to RPD group (p Conclusion OCTA provides a reproducible, non-invasive detailed quantitative analysis of retinal vascular features and changing in early-stage type 3 MNV patients, which allowed to shed the light on the main role of DCP ischemia in the development of type 3 MNV.

To measure the corneal thickness (CT), corneal epithelial thickness (CET), and corneal stromal thickness (CST) in patients affected by type 2 diabetes mellitus with good glycemic control and without any signs of diabetic retinopathy using anterior-segment optical coherence tomography (AS-OCT).60 eyes of 30 diabetic patients and 60 normal eyes of 30 healthy subjects underwent AS-OCT, evaluation of best-corrected visual acuity (BCVA), intraocular pressure (IOP), slit-lamp biomicroscopy, tear film breakup time (TBUT), Schirmer I test and fundus examination. The CT, CET, and CST maps generated corresponded to a 6-mm diameter area of the cornea that was divided into 17 sectors. We compared the CT, CET, and the CST of each sector obtained in the diabetic group with those obtained in the control group.No significant difference in terms of age, gender, BCVA, IOP, TBUT, and Schirmer I test between the two study groups was observed. The CT, CET, and CST in the central section were significantly thickened in diabetic patients than in controls (p0.001). Also, each paracentral and midperipheral sector was significantly increased in patients compared to controls (p0.05).The evaluation of the CT, CET, and CST by AS-OCT could be a valid and non-invasive biomarker in patients effected by diabetes mellitus, useful in early diagnosis of diabetic retinopathy.

Introduction/aims Non-arteritic anterior ischemic optic neuropathy (NAION) is an acute infarction of the prelaminar anterior optic disc, resulting from the occlusion of posterior ciliary arteries. Here, we evaluated the correlation between structural and vascular features in a case of resolved NAION. Methods Observational case report. Results A 50-year-old male patient was referred at an Eye clinic due to an altitudinal visual field defect in the left eye, occurred 9 months before. Fundus examination was unremarkable, while structural SD-OCT reveals retinal nerve fiber layer (RNFL), ganglion cell complex (GCC) thinning associated with reduction of peripapillary vascular density at OCT Angiography. Discussion We found a precise spatial correlation among RNFL and GCC thinning, peripapillary vascular reduction and visual field defects. This case demonstrates that OCTA represents a new, valid and non-invasive imaging technique in the diagnosis and follow-up of NAION, even after the resolution of the acute phase, in the absence of clinical signs at fundus examination.

Introduction: This study aimed to identify the changes in vessel density (VD) of the choriocapillaris (CC) and in subfoveal choroidal thickness (SFCT) and to evaluate their correlation with functional response after 3 monthly intravitreal injections of ranibizumab (loading phase [LP]) in patients affected by polypoidal choroidal vasculopathy (PCV). Methods: A total of 30 eyes of 30 PCV patients and 30 eyes of 30 healthy subjects as the control group were enrolled in this prospective study. The best-corrected visual acuity (BCVA) was measured at baseline and after 1 month from the third intravitreal injection in each patient. The VD of CC was evaluated in the macular area by means of optical coherence tomography angiography (OCTA). Central macular thickness (CMT) and SFCT were analyzed by enhanced depth imaging (EDI)-OCT. Results: The VD of CC showed statistically lower values in PCV patients at baseline with respect to after LP and normal eyes (p < 0.001). CMT and SFCT revealed a statistically significant reduction after LP (p < 0.001). Multiple regression analysis revealed a significant negative correlation between the reduced SFCT and CMT at baseline and the improvement of BCVA after LP (p < 0.05). Conclusion: The close relationship between the thinner SFCT and better visual outcome after LP reveals the role of the EDI-OCT assessment of the choroid as a predictive biomarker of functional response to anti-VEGF therapy. This tool could provide a quantitative evaluation of structural features of the choroid avoiding mistakes of evaluation at OCTA.

Highlights • A biopsy of any suspicious breast skin lesion after radiotherapy is recommended. • Patients with clinical anomalies post-breast cancer surgery and RT need attention. • The Angiosarcoma was cured due to surgery and high-dose neoadjuvant chemotherapy. • A correct 6 month follow-up is needed: check-ups, chest X-rays and ultrasound. • The survival of the patient suggests possible ways to manage this rare tumour type., Introduction Radiation-induced breast angiosarcoma is a severe but rare late complication in the breast-preserving management of breast cancer through surgery and radiotherapy. Often the initial diagnosis is complex given its relatively anodyne nature and the fact that it usually presents in the form of typically multifocal reddish-purple papular skin lesions. Presentation of the case We describe the clinical and pathologic findings of a 79-year-old woman, who developed a radiation-induced breast angiosarcoma after around 8 years. She initially refused a mastectomy leading to an adaptation in the management of this cancer. Discussion The average latency of secondary angiosarcoma of the breast following radiation therapy is around six years. Breast angiosarcoma is typically considered to affect the dermis, and is therefore cutaneous in origin. An incisional biopsy of the discoloured skin and underlying mass is necessary. The treatment is surgical resection. The role of chemotherapy has not been clearly defined. Most data originate from retrospective case series studies suggesting that angiosarcomas are relatively sensitive to taxanes and anthracyclines. Conclusion The preferred treatment is always aggressive surgical removal and, as our atypical clinical case suggests, neoadjuvant chemotherapy in very high doses is also needed. A biopsy of any suspicious breast skin lesion after radiotherapy is recommended. Despite the treatment challenges, our case provides enlightening details on the management of such a rare cancer even when faced with unplanned events which do not always allow for a textbook approach.

Blau syndrome (BS) is a rare granulomatous auto-inflammatory disease, characterized by the classic clinical triad of joints, skin and ocular involvements. Ocular manifestation usually consists in a bilateral insidious chronic anterior uveitis with a potential evolution to panuveitis. We describe the case of two siblings, an 8-years old female and a 5-years old male, with a diagnosis of BS, evaluated by Anterior Segment-Optical Coherence Tomography (AS-OCT). In the female patient, slit-lamp examination revealed bilateral anterior granulomatous uveitis and inflammatory sequelae. AS-OCT revealed high intensity reflective layers in the anterior cornea, hyperreflective dots both in the aqueous humor and in the posterior corneal surface. In the male, no signs of inflammation were detected both on slit-lamp examination and AS-OCT scans. AS-OCT is a valuable, non-invasive tool that could improve the diagnosis of ocular involvement, better characterize and follow-up corneal alterations and anterior segment features in pediatric patients with BS.
