No full textOcular argyrosis in a silver craftsman
Full text linkThis case report highlights the hazard of silver crafting without adequate eye protection, and indicates that occupational ocular argyrosis may still be observed in clinical practice today. In such cases, occupational anamnesis, ophthalmologic examination, confocal corneal biomicroscopy, and histopathology will allow the correct diagnosis that, in turn, is important for work-related medico-legal issues
Management of recurrent corneal ulcers: Use of amniotic membrane
No full textPURPOSE:
Amniotic membrane (AM), or amnion, is a thin membrane on the inner side of the fetal placenta; it completely surrounds the embryo/fetus and delimits the amniotic cavity, which is filled by amniotic liquid. In recent years, the structure and function of the amnion have been investigated due to its pluripotent properties, which are an attractive source for tissue transplantation and reconstructive surgery. The pioneering use of AM in skin transplantation by Davis dates back to 1910; in 1913, Sabella and Stern employed it in the treatment of burns and superficial scars. Certain characteristics make the AM ideally suited to its application in ocular surface reconstruction. It can be easily obtained and its availability is nearly unlimited. We report a case of AM transplantation to treat ocular surface abnormality.
METHODS:
A 28-year-old man came to our attention for persistent foreign body feeling and pain in his right eye. Because of progressive clinical worsening, we decided to perform surgical apposition of AM.
RESULTS:
Clinical and instrumental follow-up was conducted with periodic complete checkups. At 1 year follow-up, best-corrected visual acuity was 4/10
Corneal sensitivity in keratoconus afterpenetrating and deep anterior lamellarkeratoplasty
No full textPURPOSE:
To evaluate recovery of corneal sensitivity in the graft following penetrating keratoplasty (PK) or deep anterior lamellar keratoplasty (DALK) in patients with keratoconus.
MATERIALS AND METHODS:
113 eyes of 113 patients (39 females, 74 males) were examined. All eyes had undergone corneal grafting: 39 PK, 74 DALK. Corneal sensitivity tested using the Cochet-Bonnet esthesiometer was evaluated the day before and 3 days, 3, 6, 12 and 24 months after surgery. The corneal sensitivity recovery was associated with surgical techniques (PK or DALK), age and sex of recipient and donor, cadaver time and type of preservation of the cornea.
RESULTS:
The average percentage of recovery of corneal sensitivity was 91% at 2 years. Surgical techniques and other qualitative and quantitative variables did not affect the statistically significant recovery of corneal sensitivity.
CONCLUSIONS:
In both surgical techniques, PK and DALK, we noticed a good recovery of corneal sensitivity in 2 years
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
