Mind-Boggling Adriamycin Techniques You Are Not Applying
However, he reported to the clinic immediately Adriamycin chemical structure after exposure. On examination, best corrected visual acuity was 6/5 with a refraction of ?0.25 D sphere in the right eye and 1/60 with a refraction of ?0.25 D sphere in the left eye with no improvement on pinhole testing. Amsler grid testing indicated normal results in the right eye and a central scotoma in the left eye. On fundus evaluation the CDRs were 0.3 bilaterally, the retinal vessels and fovea in the right eye were normal. There was a well circumscribed round hole at the fovea in the left eye [Figure 10]. On Optical coherence tomography, the macula was normal in the right eye, and there was a full thickness macular hole with cystoid changes at the edges of the hole and increased reflectivity at the base in the left eye [Figure 11]. Fluorescein angiography of the right eye was unremarkable and there was a window defect in the left eye corresponding to the full thickness macular hole [Figure 12].

Laser pointers are comprised of a diode emitting laser light, with an energy output between 1 and 5 mW.1,2,3,4,5 Initially commercially available laser pointers were red lasers with a wavelength of 670 nm. However, other wavelengths such as green, blue, yellow and violet lasers are also available and have become popular because of their advantages. For example, green lasers LBH589 molecular weight have brighter beams visible both in daylight and night, allowing star gazing and pointing far off objects, blue and violet lasers light up to different colors depending upon where they are projected, yellow lasers dazzle like gold and are used as a laser guide star for use with astronomical adaptive optics.1,2,3,4,5,6,7 As the use of laser pointers becomes more popular, physicians need to understand which lasers can cause eye injury.1,2,3,4,5,6,7,8 Lasers are divided into four ��classes�� based on their output (Class 1 and 1 M, Class 2 and 2 M, Class 3A, 3B, 3R and Class 4).1,2,3 Class 1 lasers, (energy
