Abstract

Objective: The significant metastatic potential of uveal melanoma (UVM) lends to high mortality. Even with successful local tumor treatment, many patients will develop metastatic disease. The present study aims to elucidate the relationship between tumor-infiltrating immune cell (TIIC) diversity and survival to identify potential therapeutic targets and improve UVM prognosis.

Methods: Bulk deconvolution was used to determine the relative proportions of 22 hematopoietic TIIC from 80 UVM tumor samples. Cytolytic activity (CYT) was determined, and associated survival probabilities were mined using time-to-event data. Nominal P-values were subjected to FDR correction.

Results: High relative abundance of tumor-infiltrating naïve B cells, resting memory CD4+ T cells, and monocytes correlated with better overall and disease-free survival probability. Low relative abundance of CD8+ T cells correlated with better overall survival and disease-free survival probability. CYT correlated positively with relative abundance of naïve B cells, resting memory CD4+ T cells, and monocytes. CYT correlated negatively with relative abundance of CD8+ T cells.

Conclusion: Infiltrating naïve B cells, resting memory CD4+ T cells, monocytes, and CD8+ T cells are potential therapeutic targets in UVM that warrant further investigation. High CYT estimates associate with worse UVM survival outcomes.

Neodymium:YAG laser posterior capsulotomy in the lateral decubitus position

Here we report a novel method of performing a Neodyminium:YAG (Nd:YAG) laser posterior capsulotomy in an adult patient, unable to tolerate the procedure awake with topical anaesthesia in the outpatient clinic setting. The procedure was performed by altering the chin rest and arms of the Nd:YAG laser machine so that the procedure could be undertaken in an anaesthetized patient in the operating theatre, in the lateral decubitus position, with the laser machine upright in its normal position.

Presbyopia correcting IOLs and the ocular surface disease… The good, the bad and the ugly

The last two decades were especially fruitful for the refractive surgeons and for the industry who have been showing tremendous development in both understanding and meeting patients’ desire for spectacle independence. Ever since the first trials from Dr. Kenneth Hoffer with his early 1980’s effort in producing a multifocal IOL to the latest achievements from different companies in putting trifocals and EDOF optics to the market.

How many mutations does it take to make a uveal melanoma?

Uveal melanoma (UM) is a rare cancer that affects the choroid and, less frequently, the ciliary body or the iris (for recent reviews see [1-3]). Despite a profound knowledge of the oncogenic mechanisms behind UM tumorigenesis and despite an accurate cytogenetic and molecular prognosis, only limited advances have been made in UM therapy.

MSICS is a Simple Solution for a Big Problem

Manual small-incision cataract surgery (MSICS) is a sutureless cataract surgery that has multiple advantages over traditional phacoemulsification and extracapsular cataract extraction (ECCE) procedures. SICS became the procedure of choice for international ophthalmology, where the microscopes and operating room can be more challenging, in addition to the more advanced pathology often seen.

Surgical smoke and SARS-CoV-2 transmission

The protection of health care workers from nosocomial infection is a paramount consideration in the current pandemic involving severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Not only is prevention of viral transmission the most effective means to lessen the public health impact of coronavirus disease 2019 (COVID-19), but also both quarantine and illness – that disproportionately affect health care workers – have devastating effects on the ability of hospitals to adequately care for increased patient loads.
