Evaluation of optical coherence tomography (OCT) changes following transretinal tumour biopsy for choroidal melanoma

Emerging SERS biosensors for the analysis of cells and extracellular vesicles

“…168,169 As well as availability, in most cases these techniques are able to identify potentially dangerous tumours only when the number of tumour cells is large enough to cause an extensive release of biomarkers or metastasis has started. 170 As an analytical technique, SERS is a powerful tool for ultrasensitive analysis of small amounts of analyte, making it stand out among other techniques that require a larger amount of sample for biomarker detection. From this perspective, SERS can detect a single molecule at the designed condition.…”

Ocular oncology demystified

“…Such is the utility of ocular imaging in choroidal tumours that a biopsy (trans-vitreal or trans-scleral) is seldom required for diagnosis, but more commonly performed for prognostic information in uveal melanomas [4,5]. Counselling patients regarding the benefits versus risks on an individual basis is important.…”
