Despite the improvement of IOP level, intravitreal bevacizumab (IVB) did not reduce the overall enucleation rate in NVG following proton beam therapy. Nevertheless, this treatment was effective in the early phases of NVG or as preventive treatment. PRP remains a valid treatment for NVG.

Ocular medulloepithelioma (ME) is a rare congenital tumor which occurs usually during childhood but is also reported in adults. They have seen an intraocular tumor in an 89 years-old female with a history of small cell lung carcinoma. Transscleral fine needle aspiration was performed. Aspirates were rich and composed of two distinctive populations of cells. The first consisted of epithelioid large cohesive cells with rare rosettes. Nuclei were oval and chromatin was delicate with small nucleoli. The second population consisted of smaller and dispersed cells with regular nuclei and dusty chromatin. Immunohistochemistry performed on paraffin-embedded cell block sections showed that the larger cells and rosettes were cytokeratin AE1/AE3, Synaptophysin, Chromogranin A, CD56, NSE, and EMA positive, whereas the smaller cells were always negative. Interestingly smaller cells expressed only weak nuclear positivity for TTF1, whereas larger cells were TTF1 negative. Melanocytic markers were negative in both populations. Morphological patterns and immunohistochemical staining confirmed ocular ME and allowed to exclude pulmonary metastasis or primary malignant melanoma. The patient was successfully treated by brachytherapy alone and is alive and well 10 months after treatment. Diagn. Cytopathol. 2017;45:561-564. © 2017 Wiley Periodicals, Inc.

A 74-year-old man presented with bilateral optic nerve atrophy related to arteritic anterior ischaemic optic neuropathy (AION) which started 22 years ago. Atrophic papilla was noted in both eyes and optical coherence tomography showed thinning of the retinal nerve fibres layer as well as the macular ganglion cell complex. Optical coherence tomography angiography of the macula found a decreased density of the superficial capillary complex, whereas deep capillary complex was well-preserved. Inner retinal layer atrophy in chronic arteritic AION is followed by a loss of vascularisation in these layers as a consequence of the neurodegeneration.

As one of intraocular tumours, retinal cavernous haemangioma is a benign vascular lesion that is mostly unilateral. Very few cases about cavernous haemangioma treatment are reported, and there is currently no consensus on the most effective treatment. This clinical case reports on a 40-year-old male, presenting a peripheral retinal cavernous haemangioma, complicated with a repetitive vitreous haemorrhage causing bad vision. Several therapeutic methods were unsuccessfully attempted to stop haemorrhagic recurrences. Thanks to proton beam irradiation, a good collapse of aneurismal dilatations was obtained, with no recurrence of bleeding. This case study confirms that proton beam therapy is a good alternative in treating cavernous haemangiomas, leading to a total tumour regression without complications.
