Book Description
Recent Advances in Ophthalmology focuses on developments in ophthalmology, including therapy, keratotomy, phototoxicity, and retinopathy. The compilation first offers information on the therapy of herpes simplex, anterior segment surgery, and use of viscous and viscoelastic substances in ophthalmology. Topics include systemic antiviral agents and ocular disease; influence of new instruments and technology; criteria for the selection of viscous or viscoelastic material; and indications for the use of viscous substances. The text then ponders on radial keratotomy, intraocular lenses, and treatment of congenital cataracts. The publication takes a look at ocular phototoxicity and vitreous surgery, as well as proliferative diabetic retinopathy, posterior penetrating trauma, effects of non-ionizing radiation on biological systems, body temperature and light damage, and retinal photodamage. The text also touches on the management of diabetic retinopathy; treatment of malignant melanomas of the posterior uvea; and macular disease with serious retinal detachment. The compilation is highly recommended for ophthalmologists and readers interested in the developments in ophthalmology.

Book Description
High-speed anterior segment optical coherence tomography (OCT) offers a non-contact method for high resolution cross-sectional and three-dimensional imaging of the cornea and the anterior segment of the eye. As the first text completely devoted to this topic, Anterior Segment Optical Coherence Tomography comprehensively explains both the scientific principles and the clinical applications of this exciting and advancing technology. Anterior Segment Optical Coherence Tomography enhances surgical planning and postoperative care for a variety of anterior segment applications by expertly explaining how abnormalities in the anterior chamber angle, cornea, iris, and lens can be identified and evaluated using the Visante OCTTM. Inside Anterior Segment Optical Coherence Tomography, Dr. Roger Steinert and Dr. David Huang, along with 22 of the field's leading professionals, provide a wealth of useful clinical and physiological material about this new diagnostic imaging technique. Valuable images are included to assist in the pre- and postoperative assessment of various anterior segment disorders. Additionally, this unique resource contains detailed information on biometric measurements to enhance diagnostic capability. On the leading edge of anterior segment imaging: Mapping of corneal thickness and keratoconus evaluation Measurement of LASIK flap and stromal bed thickness Visualization and measurement of anterior chamber angle and diagnosis of narrow angle glaucoma Measuring the dimensions of the anterior chamber and assessing the fit of intraocular lens implants Visualizing and measuring the results of corneal implants and lamellar procedures Imaging through corneal opacity to see internal eye structures With the increase in popularity of anterior chamber imaging, and anterior segment OCT proving to be the best tool for high resolution biometry, Anterior Segment Optical Coherence Tomography is a must-have for anterior segment, refractive, cornea, and glaucoma surgeons.

Book Description
"Despite advances in optical coherence tomography (OCT) there is still demand for further improvements in axial and lateral resolution, imaging depth and speed. The objectives of this dissertation were to develop advanced OCT systems that overcome some of the current limitations of this technique and to advance our understanding of the mechanism of human accommodation and corneal diseases by imaging the anterior segment of the eye. A large scan depth OCT (imaging depth > 10 mm) was developed for improving our understanding of accommodation. Novel scanning optics, where scanning beams are incident normal to the four ocular surfaces (anterior and posterior cornea and lens surface) was used in the system, to maximize the OCT signal. In-vivo imaging was carried out in two young normal subjects and the four anterior segment ocular surfaces could be visualized. Six millimeter diameter posterior lens surface could be imaged without the need for pupil dilation. Reduction in anterior chamber depth, increase in lens thickness and decrease in radius of curvature in both lenticular surfaces was observed with accommodation. An ultrahigh axial resolution OCT was developed to quantify structural changes in corneal diseases. The system, based on spectral domain OCT principle, used a broadband supercontinuum light source (375 nm at center wavelength of 812.5 nm) and was assembled in free space to avoid image degradation due to dispersion. A spectrometer based on modified Czerny Turner configuration was used to achieve relatively large scan depth (~1 mm). The experimentally measured axial resolution of the system was 1.1 [mu]m in corneal tissue, which allowed for the visualization and quantification of individual corneal layers in normal and diseased corneas. The clinical viability of the system was proven through a study on structural changes in the epithelium and Bowman's layer of keratoconic eyes. In-vivo cellular imaging capability, using an optical coherence microscope, was demonstrated by imaging stromal keratocytes and endothelial cells in the mouse cornea. The system provided large working distance (30.5 mm) and also has the potential of achieving larger field if imaging speed could be improved. Thus creating the possibility of performing non-invasive follow up investigation on the cellular structure in the mouse eyes. These advanced OCT systems have successfully overcome the limitations of currently available OCT systems, by providing better axial and lateral resolution and imaging depth. With improved performance these systems can help us in understanding the diseases pertaining to the anterior segment of the eye"--Pages ix-x.
