Purpose: We report a case of acute bilateral Descemet membrane endothelial keratoplasty (DMEK) rejection two weeks following BNT162b2 mRNA COVID-19 vaccine (Pfizer-BioNTech), reflecting on possible changes to the management of patients with DMEK scheduled for COVID-19 vaccination.
Patients And Methods: A 94-year-old woman with Fuchs' endothelial dystrophy who underwent DMEK 24 months earlier (right eye) and 20 months earlier (left eye) demonstrated bilateral graft rejection two weeks after the first dose of COVID-19 vaccine. Standard treatment regimen was followed, and clinical status documented with slit-lamp examination and swept-source optical coherence tomography throughout.
Results: Preoperative best corrected visual acuity (BCVA) and corneal thickness (CT) were 0.3 and 679µm right eye and 0.2 and 668µm left eye. Postoperative BCVA and CT were 0.7 and 559µm right eye and 0.4 and 590µm left eye. Standard treatment regimen consisted of dexamethasone/tobramycin and ketorolac, four times daily. At one month, both preparations were discontinued, replaced by dexamethasone 0.1% four times daily. At three months, this was tapered to once daily. Post-rejection, BCVA and CT were 0.2 and 710µm right eye and 0.3 and 710µm left eye. Treatment was with dexamethasone/tobramycin six times daily. Poor response resulted in re-DMEK transplantation, starting in the left eye. At one-month follow-up, BCVA and CT were 0.5 and 538µm right eye and 0.63 and 504µm left eye.
Conclusion: We report the first acute bilateral DMEK graft rejection after a single dose of COVID-19 vaccine. We recommend clinicians exercise vigilance and consider dexamethasone 0.1% during the vaccination period.

Trauma exposure is common in (pre) school-aged children and around one-fifth of exposed children meet the criteria for post-traumatic stress disorder (PTSD). These symptoms can cause severe impairment to a child's functioning and, if left untreated, have negative long-term consequences. Therefore, there is an urgent need for effective treatment to reduce the acute and long-term effects of trauma.

Purpose: To analyze Tocilizumab (TCZ, an interleukin 6 inhibitor) as a second-line treatment for thyroid-associated ophthalmopathy (TAO).
Methods: In this retrospective observational study, the charts of patients with moderately severe to severe TAO who received intravenous Tocilizumab as a second-line treatment 2020-2023 were reviewed.
Results: Twenty-three patients were enrolled in the study.

A 73-year-old male with a history of incidentally diagnosed Paget disease of bone affecting the skull and left orbit 2 years prior presented with 3 months of vision loss, proptosis, and periorbital swelling of the OS. Examination showed best-corrected Snellen visual acuity of 20/150 in the affected eye, intact motility, 7 mm of relative proptosis, significant dilated and tortuous "corkscrew" conjunctival vessels, serous choroidal and retinal detachments, optic nerve hyperemia, and venous tortuosity and dilation. Although the bony lesions in the left orbit were stable from 1 year prior on imaging, the diagnostic angiogram demonstrated osseous blush and hypervascularity of the lesion.

A 59-year-old female patient presented with a purple, fluid-filled lesion on her left upper eyelid that contained a solid component. Excisional biopsy revealed a diagnosis of mucinous adenocarcinoma. Extensive oncological workup was negative for a distant primary tumor or metastasis and confirmed a diagnosis of primary mucinous adenocarcinoma.

We present the case of a 23-year-old male who experienced vision loss in his left eye 15 months after undergoing bilateral transepithelial photorefractive keratectomy (T-PRK). Despite the absence of any significant preoperative topographical risk factors in either eye, corneal ectasia was later confirmed in the left eye, while the right eye remained normal. Subtle asymmetry in topometric indices and a borderline high Index of vertical asymmetry (IVA) reading suggested the possibility of early subclinical keratoconus, potentially increasing the risk of post-refractive ectasia.
