A 71-year-old woman presented with progressive, bilateral, blurred vision and nyctalopia for the last 6 months. Her past medical history included total hysterectomy and chemotherapy for ovarian cancer 4 years ago, without metastases. Optical coherence tomography revealed outer retinal layers' thinning bilaterally, while diffuse retinal pigment epithelium abnormalities were found in fundus autofluorescence. Full-field electroretinogram showed abnormalities in both a- and b-waves with significant reduction of retinal sensitivity, affecting however more the rod system. The patient was positive for alpha-enolase and was diagnosed with cancer-associated retinopathy (CAR), which developed 4-year primary cancer. Computerized tomography scan revealed an enlarged para-aortic lymph node at the left kidney, and the patient was started on chemotherapy, combined with immunosuppressive treatment. In conclusion, CAR should be suspected in patients experiencing unexplained visual disturbances, especially in the context of previous cancer.

Despite advances in neonatal and ophthalmological care, retinopathy of prematurity (ROP) continues to be a leading cause of childhood blindness worldwide. Investigating gene variants associated with vascular responses in ROP may provide valuable insights into its pathogenesis and identify risk or protective factors. Nitric oxide (NO) and endothelin-1 (ET-1) play roles in vascular regulation, influencing processes relevant to ROP development.

Background: Depression is a severe mental disorder commonly co-morbid with diabetes, but it remains to elucidate whether depression is associated with the risks of a wide range of vascular complications in people with type 2 diabetes mellitus (T2DM) and whether metabolic biomarkers may mediate this pathway.
Methods: We conducted this prospective analysis among the participants of the UK Biobank who were diagnosed with T2DM and free of vascular complications at baseline between March 13, 2006 and September 30, 2010. Major depressive disorder (MDD) was ascertained according to the hospital admission records and self-report of doctor-diagnosed conditions, while the presence of depressive symptoms was assessed using the Patient Health Questionnaire-2.
Paraneoplastic retinopathy (PR) is a rare autoimmune condition typically associated with progressive visual loss and is often linked to anti-recoverin antibodies. Paraneoplastic optic neuropathy (PON) is classically associated with collapsin response-mediator protein (CRMP-5). We present a unique case of non-progressive CRMP-5-associated perifoveal retinitis in a 79-year-old female with a history of breast carcinoma, who has maintained a stable visual acuity over an extended follow-up period of three years.

Background: Retinal microvascular abnormalities (RMA) reflect cumulative microvascular damage from systemic diseases and aging. However, little is known about the association between RMA and long-term survival outcomes. This study aimed to examine the relationships between RMA and the risk of all-cause and specific-cause mortality among U.

Background: Diabetic Mastopathy (DMP) is an uncommon benign fibro-inflammatory condition that occurs in women with long-standing diabetes mellitus (DM), particularly type 1. It often mimics breast cancer (BC) in clinical and imaging presentations, leading to diagnostic challenges.
Methods: A retrospective monocentric study was conducted, analyzing clinical, radiologic, and pathological data from 28 women diagnosed with DMP over 10 years at the European Institute of Oncology.
