A study conducted at ATTIKON University Hospital in Athens, Greece, reported on a case of a 34-year-old man with a retropharyngeal schwannoma causing upper-airway obstruction. The patient underwent surgery to remove the tumor, resulting in the development of permanent Horner's syndrome, affecting his vision. The research highlights the importance of discussing potential complications, such as Horner's syndrome, with patients before surgical interventions for retropharyngeal tumors.

A study conducted by researchers at Nanjing Medical University in Jiangsu, China, has developed a modified iris cerclage technique to improve visual quality in patients with acute primary angle closure (PAC) and permanent mydriasis after cataract surgery. The study involved 12 patients who underwent the modified iris cerclage procedure, and improvements were observed in best corrected visual acuity, pupillary parameters, self-assessed photophobia, and visual function index-14 questionnaire scores. No postoperative complications were observed, and the modified iris cerclage technique resulted in a centered and round pupil. The research concludes that this technique can effectively improve visual quality in patients with acute PAC and permanent mydriasis after cataract surgery. [Extracted from the article]

A recent report from the Norfolk and Norwich University Hospital NHS Trust discusses the use of intracameral phenylephrine for surgical mydriasis and intraoperative floppy-iris syndrome. Phenylephrine is a sympathomimetic drug that induces mydriasis by contracting the iris dilator muscle. The researchers found little evidence of serious systemic adverse events associated with intracameral phenylephrine use, although they suspect under-reporting. They suggest using lower but effective concentrations of phenylephrine for different purposes, such as initial mydriasis. For the management of intraoperative floppy-iris syndrome, a higher concentration of phenylephrine may be required. [Extracted from the article]

A recent study conducted at MVJ Medical College and Research Hospital compared the effectiveness of Nepafenac and Flurbiprofen eye drops in maintaining intraoperative mydriasis during phacoemulsification surgery. The study involved 100 patients who were randomly assigned to receive either Nepafenac or Flurbiprofen eye drops. The results showed that both drugs were equally effective in maintaining mydriasis, but Nepafenac was slightly better than Flurbiprofen. This research is significant because cataracts are a leading cause of preventable blindness worldwide, and phacoemulsification is the preferred surgical technique for treating cataracts.

A recent study conducted at Lagos State University Teaching Hospital in Nigeria compared the effectiveness of different mydriatic agents in manual small incision cataract surgery (MSICS) in a black population. The study found that using an intracameral solution of lidocaine and adrenaline provided adequate mydriasis for the successful completion of MSICS without the need for pre-operative dilation. The study measured pupil sizes before and during surgery and found that the intracameral group had significantly larger pupil sizes at each point of measurement. Post-operative visual acuity was similar between the two groups. This research provides valuable insights into improving cataract surgery techniques in black populations.

A recent report from Chongqing University in China discusses Horner syndrome (HS), a rare complication of thyroid surgery. The report focuses on a case study of a 24-year-old female who developed HS immediately after endoscopic thyroidectomy for thyroid papillary carcinoma. The researchers analyzed the relationship between deep dissection of the upper thyroid pole and the occurrence of HS, providing insights for clinicians to avoid this complication. The study highlights the need for further research in this area. [Extracted from the article]
