AIM: To determine whether there is a significant correlation between the reduction in macular vessel density and the recurrence of macular oedema in eyes with branch retinal vein occlusion (BRVO). METHODS: We reviewed the medical records of 27 eyes with macular oedema associated with BRVO. All eyes had received pro re nata intravitreal ranibizumab (IVR) injection. A reinjection of ranibizumab was performed when the central foveal thickness was ≥300 µm. At 12 months, patients without additional IVR for the last 4 months were placed in the resolved group, otherwise they were placed in the recurrence group...

BACKGROUND/AIMS: To characterise neuroretinal atrophy in retinal vein occlusion (RVO). METHODS: We included patients with central/branch RVO (CRVO=196, BRVO=107) who received ranibizumab according to a standardised protocol for 6 months. Retinal atrophy was defined as the presence of an area of retinal thickness (RT) <260 µm outside the foveal centre. Moreover, the thickness of three distinct retinal layer compartments was computed as follows: (1) retinal nerve fibre layer to ganglion cell layer, (2) inner plexiform layer (IPL) to outer nuclear layer (ONL) and (3) inner segment/outer segment junction to retinal pigment epithelium...

BACKGROUND: Protein tyrosine phosphatases (PTPs) play critical roles in human autoimmunity. Previous studies found that PTPN2 may be the key regulatory factor in the T-cell-mediated immune response. PTPN2 regulates the Janus kinase/signal transducers and activators of transcription pathway by inhibiting signalling via the interleukin (IL)-2 receptor (CD122). An association between genetic variations in PTPN2 and CD122 with ocular Behcet's disease (BD) has not yet been addressed and was therefore the purpose of this study...

BACKGROUND: p53 is a stress-activated tumour suppressor gene, and its mutation has been associated with solid tumours including non-melanoma skin cancers. Sestrin2 expression is associated with DNA damage and oxidative stress and has been described as a downstream target of p53 network. However, its role in sebaceous gland carcinoma (SGC) remains unexplored. OBJECTIVES: To determine the role of p53 and its downstream target gene sestrin2 expression and p53 gene mutation status in SGC...
