Case Reports
Epilenticular intraocular lens implantation in traumatic cataract with a ruptured posterior capsule.
To present a case of rapidly progressing traumatic cataract caused by posterior capsule rupture after nonpenetrating ocular injury, as well as a surgical procedure to safely implant the intraocular lens in such a traumatized eye. ⋯ We present a method of intraocular lens implantation in cases of rapidly progressing traumatic cataract caused by posterior capsule rupture after a blunt ocular trauma.

Case Reports Comparative Study
Amsler grid examination and optical coherence tomography of a macular hole caused by accidental Nd:YAG laser injury.
To compare a macular hole from accidental Nd:YAG laser injury with idiopathic macular holes. ⋯ The scotoma caused by Nd:YAG laser injury is not surrounded by distortion; the hole is produced by the defect of all retinal layers. In contrast, idiopathic macular holes generally produce a pincushion pattern on Amsler grid testing and have no tissue loss.

To provide an understanding of the structure, role, and responsibility of the International Federation of Ophthalmological Societies, the International Council of Ophthalmology, and the International Congress of Ophthalmology. These established entities have recently codified their statutes and regulations and registered them in Zurich, Switzerland. ⋯ The statutes and regulations of the International Federation of Ophthalmological Societies, the International Council of Ophthalmology, and the International Congress of Ophthalmology provide a basis for an organizational structure in international ophthalmology. The International Congress of Ophthalmology, first held in 1857, is the longest continuing international meeting in medicine. The International Council of Ophthalmology was established in 1927, and the International Federation of Ophthalmological Societies was formed in 1933. These organizations coordinate the International Congress of Ophthalmology, which convenes with the International Federation of Ophthalmological Societies every 4 years. The International Council, as the executive body, meets annually. The International Council of Ophthalmology has for decades worked to coordinate and facilitate interchange, education, and standards in international ophthalmology. Currently, the International Council of Ophthalmology, working with other international organizations, is creating an international ophthalmology strategic plan, which includes focus on ophthalmic training, continuing education, advocacy for the preservation and restoration of vision, clinical guidelines, and research.

Comparative Study
Measurement of microcirculation in the optic nerve head by laser speckle flowgraphy and scanning laser Doppler flowmetry.
To evaluate and compare blood flow measurements by laser speckle flowgraphy and scanning laser Doppler flowmetry in the optic nerve head of normal volunteers. ⋯ We found only a weak correlation between the blood flow indexes, as measured by laser speckle flowgraphy and scanning laser Doppler flowmetry because of basic differences in the principles of measurement.
