In this review, we show an update of the most common comorbidities in patients with SpA, and we discuss the latest evidence on the management of such comorbidities. To relate conjunctival melanoma characteristics to local control. Retrospective, registry-based interventional study with data gathered from 10 ophthalmic oncology centres from 9 countries on 4 continents. https://www.selleckchem.com/products/vcmmae.html Conjunctival melanoma patients diagnosed between January 2001 and December 2013 were enrolled in the study. Primary treatments included local excision, excision with cryotherapy and exenteration. Adjuvant treatments included topical chemotherapy, brachytherapy, proton and external beam radiotherapy (EBRT). Cumulative 5-year and 10-year Kaplan-Meier local recurrence rates were related to clinical and pathological T-categories of the eighth edition of the American Joint Committee on Cancer (AJCC) staging system. 288 patients had a mean initial age of 59.7±16.8years. Clinical T-categories (cT) were cT1 (n=218,75.7%), cT2 (n=34, 11.8%), cT3 (n=15, 5.2%), cTx (n=21,7.3%) with no cT4. Primary treatment included local excision (n=161/288, 55.9%) followed by excision biopsy with cryotherapy (n=108/288, 37.5%)gh despite current management. This multicentre international study showed that eighth edition of AJCC tumour staging was related to the risk of local recurrence of conjunctival melanoma after treatment. The 10-year cumulative local recurrence remains high despite current management. To investigate clinical characteristics and risk factors for glaucoma conversion of the contralateral eye in unilateral normal-tension glaucoma (NTG) patients. A retrospective observational cohort study was conducted on a total of 76 subjects who had been diagnosed with unilateral NTG at the baseline and followed up for more than 5years. Glaucoma conversion in the contralateral eye was defined as increased thinning of neuro-retinal rim, development of retinal nerve fibre layer defect and/or development of glaucomatous visual field defect. During the mean follow-up period of 7.3±2.4years, 21 of 79 (26.6%) subjects were confirmed to have developed glaucoma in the non-glaucomatous contralateral eye. The 5-year rate of glaucoma conversion in contralateral eyes was 19.7%. The maximum width of β-zone parapapillary atrophy (MWβPPA)-disc diameter (DD) ratio at the baseline and the presence rate of disc haemorrhage during follow-up period were significantly greater in the contralateral eyes of the conversion group than in those of the non-conversion group (p 0.011, <0.001, respectively). A multivariate Cox-proportional hazard model revealed intraocular pressure (IOP) over 17 mm Hg (HR 5.05, p=0.031), central corneal thickness (CCT) under 491μm (HR 4.25, p=0.025) and MWβPPA-DD ratio over 0.32 (HR 6.25, p=0.003) in contralateral eye at the baseline as the independent risk factors for glaucoma conversion. Among unilateral NTG patients, those with low CCT and high MWβPPA-DD ratio as well as high IOP in the contralateral eye are more likely to develop glaucoma in that eye during long-term follow-up. Among unilateral NTG patients, those with low CCT and high MWβPPA-DD ratio as well as high IOP in the contralateral eye are more likely to develop glaucoma in that eye during long-term follow-up. To describe the results of all ocular surface biopsies performed on patients with xeroderma pigmentosum (XP) under the care of the UK Nationally Commissioned XP Service as well as the treatment of any subsequent ocular surface conditions diagnosed. Retrospective analysis of medical records. All patients with XP seen by the service from 2010 to 2019 were included and those with ocular surface biopsies were identified. Data was collected on demographics, complementation subgroup (A-G and V), biopsy details, histopathological analysis and subsequent management. Of 108 patients seen in our service, 17 underwent at least one ocular surface biopsy. 45 biopsy samples were available from 13 patients of which 65% were performed on patients from complementation subgroup C (XP-C). Biopsies were categorised as either non-mapping (clinically abnormal ocular surface tissue) or mapping (multiple sites including clinically normal tissue). 67 percent of non-mapping biopsies had a mass as their indication and 46% showed ocular surface squamous neoplasia. General non-dysplastic damage was seen in 67% of non-mapping biopsies and melanocytic changes were seen in 25% of non-mapping and 81% of mapping biopsies. 47 percent of biopsy outcomes required no additional treatment but, of those that did, 50% received mitomycin C. This is the largest reported series of ocular surface biopsies in patients with XP. It identifies a background of ocular surface melanocytic, degenerative and inflammatory changes, with patients with XP-C showing the most severe effects. We highlight challenges faced in interpreting their histopathology and in planning subsequent treatments. This is the largest reported series of ocular surface biopsies in patients with XP.

To describe optical coherence tomography angiography (OCTA) features of polypoidal choroidal neovascularisation (PCNV) secondary to age-related macular degeneration. A retrospective consecutive series of 51 patients with a diagnosis of PCNV, based on clinical and multimodal imaging, was analysed. All patients with PCNV underwent a comprehensive ophthalmological examination, including fluorescein and indocyanine green angiography, structural optical coherence tomography (OCT) and OCTA. Two blinded retinal specialists carefully reviewed OCTA slabs in order to assess the morphological patterns of PCNV lesions. Furthermore, fractal analysis of PCNV en face images on OCTA, including vascular perfusion density (VPD), fractal dimension (FD) and lacunarity (LAC), was performed. Fifty-one PCNV eyes were included in the study. In all, the branching vascular network appeared hyper-reflective. Polyps showed two different patterns in 34/51 (67%) eyes, they corresponded to hypo-reflective structures, whereas in the remaining 17 (33%) eyes, they appeared as hyper-reflective lesions.
