NCT07132437
One dose group of 0.004% was used.
NCT06983652
This observational study aims to validate the use of THz scanning system in corneal edema and corneal scars, and to investigate the accuracy and performance on the use of THz scanning system in the evaluation of the progression of corneal edema and corneal scars. Participants corneal scars and corneal edema will undergo THz scanning, followed by a series of conventional clinical examinations for detailed characterization of the corneal lesion. The performance of the use of THz system on corneal scars and edema will be evaluated by correlating measurements from the THz scans with those obtained from standard clinical methods. The investigators hypothesize that the THz scanning system has the capacity to evaluate the hydration level on human corneas.
NCT06967792
This observational study aims to establish the safety profile of the use of Terahertz (THz) scanning system on corneal diseases. Participants with "non-seeing" eyes but normal corneas will undergo THz scanning. Eye examinations will be conducted at baseline, immediately after scanning, and at 1 day, 1 week, and 1 month post-scanning. These examinations will include measurements of visual acuity, eye structural, retinal health, corneal cell morphology, and corneal nerve status. The investigators hypothesize that the THz scanning system is safe for application to the human cornea.
NCT05833737
In the upcoming years, more and more ophthalmologists will be confronted with patients receiving Belantamab mafodotin (Belamaf) treatment due to the promising effects on survival in multiple myeloma patients. Early, at best subclinical detection of corneal damage may contribute to the definition of the optimal dosing regimen as well as therapy interval in each patient without the need to stop this lifesaving treatment. However, until today, studies focusing on the development, morphology, and evolution of corneal epithelial changes associated with Belamaf treatment are scarce. In order to clarify the precise pathomechanism of the associated keratopathy, innovative imaging techniques such as corneal confocal microscopy (CCM) need to be used to follow patients prior to therapy and on a regular basis during treatment intervals. In specific, different regions of the cornea, including the central apex, the (mid-) periphery and the limbus need to be explored. The latter, in specific, is often claimed to play an important role in the uptake of Belamaf into the cornea, but has not been studied in any approach so far. Likewise, there are no reports on the effects of Belamaf on corneal layers adjacent to the corneal epithelium, in specific the subepithelial nerve plexus (SNP). Changes in this layer may suggest a potential peripheral neurotoxic/neurodegenerative effect, associated with Belamaf. Furthermore, there is a lack of evidence from literature on how changes in the anterior layers of the cornea as studied with confocal microscopy in patients on Belamaf treatment differ from distinct corneal changes in these same layers in patients with other anterior corneal diseases including keratokonjunctivits sicca, epithelium basement membrane dystrophy and limbal stem cell disease. At last, regeneration of the corneal surface after Belamaf discontinuation has been described and is expected, but detailed information on the time to corneal rehabilitation as well as confocal microscopic follow-up of epithelial and neuronal layers during this time is warranted. The purpose of this monocentric, prospective longitudinal study is to answer these specific research questions in a combined clinical approach using corneal confocal microscopy.
NCT06451172
The purpose of this study is to evaluate the safety and efficacy of GP-asPNA for in vivo treatment of severe antibiotic resistant bacterial keratitis.
NCT04421300
The objective of the study is to evaluate the effectiveness of laughter therapy in relieving the symptoms of dry eye disease.
NCT03436576
The purpose of this study is to compare the effects of autologous serum 20% and autologous serum 50% for the treatment of Severe Dry Eye Syndrome
NCT00810472
Penetrating keratoplasty is one of the most commonly performed transplantation surgeries. Graft rejection is a major complication. HLA compatibility has already been demonstrated an effective prophylaxis in several retrospective investigations. The purpose of the investigators randomized clinical trial is to demonstrate superiority of HLA matching in comparison to random graft assignment with respect to the endpoint 'time to first endothelial graft rejection' in penetrating keratoplasty. The investigators will perform DNA-based allele resolution typing.
NCT00029185
This is a compassionate-use treatment study to provide Dehydrex to patients with corneal erosion syndrome who have previously used Dehydrex.
NCT00447187
This was a pivotal trial to determine whether LX201 reduces the likelihood of a graft rejection episode following corneal transplantation in patients at high immunological risk for rejection.
