Introduction: To report by using topical anesthesia for standing phacoemulsification and intraocular lens implantation for two patients who need cataract extraction but unable to lie flat with marked cervical kyphosis due to long-standing ankylosing spondylitis and chronic uveitis. Methods: Two patients are unable to lie flat respectively during phacoemulsification underwent this technique in J...

OBJECTIVE The objective of this study was to present the outcome of the internal limiting membrane (ILM) peeling flap technique for a treatment-naïve, flat edge (Type II), full-thickness macular hole (MH). METHODS A 52-year-old man presented with complaints of decreased vision and seeing black spot. He was diagnosed to have a flat edge, full-thickness MH, which was confirmed by optical cohere...

In this paper, we discuss techniques for the quantification of random and periodic noise present in flat field images. The types of noise studied are: (1) One-dimensional periodic noise (banding); (2) One-dimensional random noise (streaking) and, (3) Two-dimensional random noise (grain). A spectral separation technique was developed which allows the estimation of the individual noise power spec...
