Abstract
PURPOSE To analyze and classify neurofibromatosis Type 1 (NF1)-related retinal vascular abnormalities (RVAs), their natural history and correlation with disease severity, in a large cohort of patients. METHODS This was an observational longitudinal study with prospective enrollment. Four hundred and seventy-three patients affected by NF1 and 150 age-matched healthy subjects were consecutively enrolled. Retinal vascular abnormalities were detected by means of near-infrared reflectance and studied by optical coherence tomography angiography. The superficial vascular plexus and the deep vascular complex (DVC) were quantitatively and qualitatively analyzed. RESULTS We identified RVAs in 82 of 473 (17%) NF1 patients, but in none of the 150 healthy subjects. A comparison revealed that NF1 patients with RVAs showed a higher number of NF1 diagnostic criteria (4.3 ± 1.5 vs. 3.9 ±1.5, respectively; P = 0.02) than patients without RVAs. Three different RVA types were identified on optical coherence tomography angiography: macrovascular angiomatosis of the sole superficial vascular plexus; macrovascular angiomatosis of the superficial vascular plexus combined with microvascular angiomatosis of the deep vascular complex; and combined macrovascular angiomatosis of both superficial vascular plexus and deep vascular complex. The prospective analysis of optical coherence tomography angiography images showed no significant longitudinal evolution of RVAs (mean follow-up: 3.7 ± 2.8 years). A single patient developed a de novo single RVA, and two RVAs showed detectable changes during follow-up. CONCLUSION In NF1 patients, RVAs are a characteristic sign that correlates with a more severe systemic disease expression, usually remaining stable during time. Optical coherence tomography angiography allows for the identification of different RVAs subtypes.

Abstract
Inflammatory, angiogenic, and immune processes have been associated with uveal melanoma (UM). The aim of the present study was to evaluate the presence of some specific aqueous humor (AH) soluble biomarkers in eyes affected by UM. Thirty-five eyes affected by primary UM and 35 control eyes, scheduled for cataract surgery, underwent full ophthalmic examination and AH sampling at time of surgery (brachytherapy or cataract surgery, respectively). AH samples were analyzed by means of ELISA, to detect the concentration of selected cytokines, chemokines, and growth factors. Compared with the control group, higher levels of IL-6 (P = .049), IL-8 (P = .006), RANTES (P = .008), EGF (P = .032), bFGF (P = .016), MIF (P = .007), and MCP (P = .020) were detected in eyes with UM. VEGF concentration between the two groups was statistically borderline (P = .058). Comparison between clinical characteristics and cytokine concentrations showed a positive correlation between tumor thickness and IL-8 (P = .032), and degree of serous retinal detachment and IL-6 (P = .021). UM is characterized by the presence of retinal neuroinflammatory, angiogenic, and immune biomarkers in AH. The proteomic analysis of AH could characterize UM microenvironment, allowing to better understand its pathophysiology.

Abstract
Intraocular tumor diagnosis is based on clinical findings supported by additional imaging tools, such as ultrasound, optical coherence tomography and angiographic techniques, usually without the need for invasive procedures or tissue sampling. Despite improvements in the local treatment of uveal melanoma (UM), the prevention and treatment of the metastatic disease remain unsolved, and nearly 50% of patients develop liver metastasis. The current model suggests that tumor cells have already spread by the time of diagnosis, remaining dormant until there are favorable conditions. Tumor sampling procedures at the time of primary tumor diagnosis/treatment are therefore now commonly performed, usually not to confirm the diagnosis of UM, but to obtain a tissue sample for prognostication, to assess patient's specific metastatic risk. Moreover, several studies are ongoing to identify genes specific to UM tumorigenesis, leading to several potential targeted therapeutic strategies. Genetic information can also influence the surveillance timing and metastatic screening type of patients affected by UM. In spite of the widespread use of biopsies in general surgical practice, in ophthalmic oncology the indications and contraindications for tumor biopsy continue to be under debate. The purpose of this review paper is to critically evaluate the role of uveal melanoma biopsy in ophthalmic oncology.

Abstract
AIMS To investigate peripapillary vascular changes secondary to radiation optic neuropathy (RON) using optical coherence tomography angiography (OCT-A) and to propose a clinical grading of RON based on OCT-A findings. METHODS Thirty-four patients affected by RON were consecutively included. Each patient underwent best corrected visual acuity measurement (ETDRS score) and OCT-A (Nidek RS-3000 Advance device, Nidek, Gamagori, Japan). The radial peripapillary capillary plexus (RPCP) and the entire peripapillary capillary bed (EPCB) were analysed. Quantitative analysis of the OCT-A images was performed using open-source available ImageJ software (National Institutes of Health, Bethesda, Maryland, USA). Qualitative analysis based on the proposed clinical grading (Grades 0-4) was also performed by two masked graders. RESULTS RON clinical (qualitative) classification based on RPCP correlated with the quantitative RPCP perfusion analysis (P=0.0001). RON clinical classification based on RPCP statistically correlated with ETDRS score (P=0.001). RON clinical classification based on EPCB also correlated with the quantitative EPCB perfusion analysis and ETDRS score (P=0.02 and P=0.01, respectively). Compared with the clinical classification based on EPCB, the qualitative classification based on RPCP reached a higher intergrader agreement (0.96 and 0.86, respectively). CONCLUSION OCT-A can be used to detect RPCP abnormalities and to clinically classify RON with a high interexaminer agreement. The proposed clinical classification is supported by the quantitative analysis based on the use of specific images elaboration techniques and correlates with visual acuity of the examined eyes.

Abstract
AIMS To evaluate the efficacy and duration of activity of a single intravitreal dexamethasone implant in patients affected by radiation maculopathy. METHODS Thirteen consecutive eyes of 13 patients affected by radiation maculopathy secondary to eye irradiation for a primary uveal melanoma (Iodine-125 brachytherapy) and treated with a single intravitreal 0.7 mg dexamethasone implant were retrospectively evaluated. Each patient underwent full ophthalmological examination, including fluorescein angiography and spectral domain optical coherence tomography (SD-OCT), even in en-face modality. Follow-up was performed monthly over a 6-month period. RESULTS At preinjection visit, the median central subfield thickness (CST) by SD-OCT was 407 µm (IQR, 357-524 µm) and the median best-corrected visual acuity (BCVA) was 61 ETDRS score (IQR, 54-67). The median gain of ETDRS letter at 1 month was 6.5 (IQR, 4-15) (p<0.01). The median CST showed a reduction of 120 µm (IQR, 62-134) (p<0.01). Further CST reduction was reported at 2 months' follow-up, with CST stabilisation at 3 months and maintenance of BCVA. At 4, 5 and 6 months' follow-up, all patients presented progressive retinal thickening (p<0.01) and BCVA reduction (p<0.01). No side effects were documented. CONCLUSION Intravitreal dexamethasone implant reduces macular oedema secondary to radiation maculopathy and also improved visual acuity in a consistent proportion of patients. Signs of macular oedema recurrence may be detected at a median of 4 months after injection.

Abstract
Aims To report long-term clinical outcome of topical 1% 5-fluoruracil (5-FU) as a sole treatment of ocular surface squamous neoplasia (OSSN). Methods 41 patients affected by OSSN were included. Each patient underwent full ophthalmological examination at baseline, with cytological or histological confirmation. Patients were treated by topical chemotherapy with 1% 5-FU four times a day for 4 weeks. One course was defined as 4 weeks of topical chemotherapy. Adjunctive courses were administered after 1 month of chemotherapy-free interval. Results Mean follow-up was 105±32 months (range 60–171 months). Complete tumour regression was achieved in 34 cases (83%) after a mean of 1.5 courses (range, 1–3 courses). Univariate analysis revealed that complete response was significantly related to tumour thickness <1.5 mm (p=0.005), lack of fornix or tarsal involvement (p=0.015 and p=0.009, respectively) and the absence of multifocality (p=0.002). Histopathological diagnosis (intraepithelial neoplasia vs squamous cell carcinoma, p=0.019) and American Joint Committee on Cancer (AJCC) classification (T1 vs T2 or T3) (p=0.028) were also related to incomplete tumour response. In a multivariate analysis, just tumour thickness >1.5 mm (p=0.045) and multifocality (p=0.023) were correlated with incomplete tumour response. Transient and reversible low-to-mild local side effects were documented in 19 (48%) eyes. Conclusion Topical 5-FU, as a sole therapy, is a long-term safe and effective treatment for patients affected by preinvasive OSSN and for a limited proportion (50%) of invasive OSSN.
