Introdouction: Cone-beam computed tomography (CBCT) scanning is a technological innovation developed in recent years with potential use in oral surgery and many other dental procedures. The aim of this study is to determine the maxillary sinus mucosal thickening in the maxillary premolar-molar area using the CBCT technique. Materials and methods: In this retrospective study, a total of 105 c...

PURPOSE To compare the outcomes of femtosecond laser-assisted cataract surgery (FLACS) with those of conventional phacoemulsification surgery (CPS) for age-related cataracts. METHODS A comprehensive literature search of PubMed, EMBASE, and the Cochrane Controlled Trials Register was conducted to identify randomized controlled trials (RCT) and comparative cohort studies comparing FLACS with CP...

PURPOSE Between days 8 and 14 of neonatal development, the corneal stroma of the mouse undergoes critical changes in tissue thickness, cell density, and light scattering. The authors investigate the stromal matrix structure in wild-type and lumican-deficient corneas in this developmental phase. METHODS Wild-type (n = 44) and lumican-deficient (n = 42) mouse corneas at neonatal days 8, 10, 12,...

PURPOSE In animal models, it has been shown that the retina can use the defocus of the projected image to control emmetropization. Glucagon may be involved in the sign of defocus detection, at least in chickens. Since glucagon and insulin often have opposite effects in metabolic pathways, the effect of insulin on eye growth was investigated. METHODS Chicks were treated with either positive or...

purpose: to evaluate the correlation between corneal power and corneal horizontal white to white diameter in myopic patients scheduled for lasik surgery. methods: overall, in 840 eyes of 420 myopic subjects scheduled for lasik, horizontal white to white diameter and mean corneal power were obtained using orbscan ii. pearson correlation test and regression analysis were used to detect any correl...

Massive Retinal Gliosis in Neurofibromatosis Type 1 Neurofibromatosis type 1 (NF1), an autosomal dominant syndrome, has major extraocular expressions of bilateral ptosis, diffuse and plexiform neurofibromas, optic nerve gliomas, and dysplasia of the sphenoid bone. With respect to the eyeball, the spectrum of involvement includes enlarged corneal nerves, Lisch iris nodules, dysplasia of the ante...

PURPOSE We used a rabbit model to evaluate the interface embedded between the recipient corneas and transplanted donor corneal discs after non-Descemet's stripping automated endothelial keratoplasty (nDSAEK). METHODS Unilateral DSAEK and nDSAEK surgeries were performed on New Zealand white rabbits. In vivo confocal microscopy was performed to show: the changes in corneal endothelial cells emb...

We read with great interest the article by Kanellopoulos and Asimellis1 and the subsequent correspondence with Reinstein et al.2 with the debate regarding the law that drives epithelial remodeling and the healing process. Kanellopoulos and Asimellis explained their findings of epithelial thickening after myopic LASIK with their hypothesis that epithelial behavior is related to the biomechanics ...

purpose : to evaluate the effects of topical sesame oil in the treatment of severe corneal alkali injury in rabbits methods : in a double-blind experiment, 30 healthy white rabbits were randomized into a sesame oil treatment group (n=15) and a control group (n=15). under general anesthesia, severe corneal alkali injuries were induced by application of 1 n sodium hydroxide for 40 seconds to the ...
