Article Synopsis
  • - The study aimed to evaluate the consistency of macular architecture measurements in patients with glaucoma, ocular hypertension, and healthy individuals using spectral-domain optical coherence tomography (SD-OCT), while also examining the effect of intraocular pressure (IOP) fluctuations during the day.
  • - A total of 394 eyes underwent two SD-OCT and IOP measurements on the same day, with results showing that measurements were highly reproducible across all groups, with high intraclass correlation coefficients (ICC > 0.90).
  • - Although significant differences in measurements were found between the glaucoma and control groups, and a weak positive correlation was noted between IOP fluctuations and the ganglion cell layer, the overall variability in measurements did not appear to be

Article Synopsis
  • A 74-year-old kidney transplant patient developed iatrogenic Kaposi's sarcoma (KS) affecting his lower eyelids and later confirmed in the left forearm and suspected in the lungs.
  • The tumor on the eyelids was surgically removed with clean margins, while the forearm lesion was also excised. The patient received radiotherapy for lung issues and adjustments to his immunosuppressive therapy.
  • The case underscores the need for early detection of KS, thorough histological diagnosis, surgical removal, and teamwork among medical professionals for effective treatment outcomes.

In recent years new modern therapeutic concepts have been developed in the treatment of malignant eyelid tumors; however, surgical restoration remains an important component of the therapeutic options addressed, which include microsurgical tumor excision into healthy tissue and subsequent coverage of the defects. An ophthalmic surgeon experienced in oculoplastic surgery is responsible for the recognition and evaluation of the existing alterations and planning a procedure together with the patient that meets the patient's expectations. The planning of surgery must always be individualized and fit the initial findings.

Article Synopsis
  • The study explores a combined surgical approach using both endoscopic transnasal and sublabial transantral methods for treating orbital lesions in patients.
  • Out of 10 patients, 8 underwent the simpler mononostril approach, while 2 required the combined method, which provided better visibility and instrument maneuverability.
  • The findings suggest the two-portal approach is effective for complex lesions and may be safer than traditional binostril methods.

Background: The last definition of the post-enucleation socket syndrome (PESS) by Tyers and Collin-formulated almost 40 years ago in 1982-is predominantly based on the clinical characteristics and does not include the insights of newer studies into the pathophysiological mechanism of the PESS.

Methods: A systematic PubMed literature review regarding the pathophysiological mechanism of the PESS was performed, and results were comprised to give an overview of the current knowledge of the PESS including the exact pathophysiological mechanism.

Results: The primarily postulated pathophysiological mechanism of the PESS was the atrophy of orbital tissues, especially of fat, resulting in variable clinical findings.

Since the beginning of 2020, SARS-CoV-2, the pathogen of COVID-19, has led to a global pandemic that also affects ophthalmology. Ophthalmologists can be confronted at any time with potentially COVID-19 associated ocular symptoms or manifestations in patients and also become infected through close patient contact. Even without systemic infection, the ocular surface can come into direct contact with aerosols or liquids containing SARS-CoV-2 particles.

A concise, ()-selective ring-closing metathesis (RCM) route to the 14-membered carbocycle of bielschowskysin is detailed using naturally occurring chiral starting materials. Unproductive RCM substrates were attributed to alkyne chelation of the ruthenium catalyst and steric disadvantages within the cembranoid precursors, which was eventually circumvented by using cyclic diol benzylidene protection involving a C8-quaternary carbinol center.

The gold standard for the treatment of periocular basal cell carcinoma is surgical resection followed by ophthalmoplastic reconstruction. The highest priority in most cases is the complete histopathologically controlled tumor excision. The histopathological preparation can be carried out in two stages by rapid overnight embedding or intraoperatively by a rapid frozen section procedure.

Article Synopsis
  • Retrobulbar haematoma (RBH) is a rare but serious condition that can occur after trauma or surgery, potentially threatening vision.
  • Early diagnosis and surgical intervention are crucial to prevent permanent vision loss, as increased pressure in the eye can compress the optic nerve.
  • Treatment typically involves a lateral canthotomy to relieve pressure, which can be done in the emergency room and may be necessary without imaging; if it fails, further surgery may be required, and systemic steroids are recommended for support.
