With the rapid development of computer science and technologies in recent years, there has been dramatic advance in anterior segment imaging. As we have mentioned in the call for papers for this special issue, manuscripts are covering the topics of anterior segment imaging techniques including anterior segment optical coherence tomography (OCT), specular microscopy, corneal topography, confocal...

The purpose of this thesis is to describe the development of an anatomically based, young adult eye model, which includes a crystalline lens with a gradient refractive index (GRIN). This model will then be used to investigate the effect of laser refractive surgery. The first step in this process involved developing a symmetrical eye model that was found to be a better predictor of empirical lon...

The corneal topographer is an indispensable tool and plays a critical role in the practice of refractive surgery. In corneal refractive surgery, corneal topography is used preoperatively to detect irregular astigmatism, ectatic corneal disorders, or other abnormalities, and to monitor topographic stability following discontinuation of contact lens wear. Postoperatively, it is used to monitor an...

PURPOSE To determine the efficacy of photodynamic therapy (PDT) with verteporfin (Visudyne; Novartis AG, Basel, Switzerland) for treatment of corneal neovascularization in a rabbit eye model. METHODS Corneal neovascularization was induced in Dutch belted rabbits by placing an intrastromal silk suture near the limbus. Verteporfin was administered by intravenous injection at a dose of 1.5 mg/kg...

purpose : to determine the efficacy of fibrin glue in corneal perforations up to 3 mm in diameter methods : a case series study was performed on corneal perforations up to 3 mm who were admitted at farabi hospital- tehran. age, visual acuity, presence and size of corneal thinning, corneal epithelial defect, size and depth of corneal infiltration, site and size of corneal perforation, corneal va...

purpose: to report a case of anterior segment eye deposits in a patient on long-term chlorpromazine therapy. case report: a 34 years old man had been on chlorpromazine therapy for 5 years with a total dose of 1,100 gram. since one year ago, he presented with gradual onset of decreased visual acuity in both eyes. slit-lamp examination revealed multiple fine yellow-brown deposits on the corneal e...

Purpose: To evaluate the efficacy and reliability of a low-energy femtosecond laser with a high repetition rate for construction of deep anterior donor corneal lamellae. Methods: This was a prospective laboratory investigation. Twenty-five human corneal buttons were femtosecond laser cut to create thick anterior lamellae (diameter, 10mm; thickness, 500μm). The laser cuts were made using an LDV ...

Objective- To compare the effects of topical eye-drop and subconjunctival administration of diclofenac on improvement of experimental corneal alkali wound in rabbits eyes. Design- Experimental study. Animal- fifteen rabbits. Procedures- Alkali wounds were inflicted on the central corneas of 15 rabbits which we...
