Effect of 0.15% sodium hyaluronate on tear film breakup time in healthy anesthetized cats.

Objectives: This study aimed to evaluate the effect of 0.15% sodium hyaluronate (SH) on tear film breakup time (TFBT) in healthy anesthetized cats.

Procedures: Forty cats undergoing elective surgery were enrolled.

The porcine corneal surface bacterial microbiome: A distinctive niche within the ocular surface.

Purpose: The ocular surface microbiome has been described as paucibacterial. Until now, studies investigating the bacterial community associated with the ocular surface through high-throughput sequencing have focused on the conjunctiva. Conjunctival samples are thought to reflect and be representative of the microbiome residing on the ocular surface, including the cornea.

[Neoplasms associated with esophageal epidermoid carcinoma].
