Pseudophakic Residual Astigmatism

We investigated pseudophakic residual astigmatism in order to minimize postoperative refractive astigmatism. We examined 110 eyes of 87 patients who had undergone phacoemulsification with small incision and posterior chamber intraocular lens (IOL) implantation. Corneal astigmatism was measured using an autokeratometer (RK-5, canon), refractive astigmatism by manifest refraction, and residual astigmatism by vector analysis. Mean pseudophakic residual astigmatism was +0.47 X 176degrees, predominantly against-the-rule. Variations of pseudophakic residual astigmatism according to sex, age and IOL type were not statistically significant. When performing cataract surgery as refractive surgery, we may consider that pseudophakic residual astigmatism is approximately 0.50D against-the-rule.

Purtscher's retinopathy due to safety belts

PURPOSE: We report one case of Purtscher's retinopathy related to chest compression by safety belts during motor vehicle accident. METHODS: A 31 old year man was referred to our ophthalmologic department because of diminished vision in the left eye at 6 days after motor vehicle accident. Best uncorrected visual acuity (UCVA) was right eye 1.0 and left eye 0.5. RESULTS: Best corrected visual acuity (BCVA) was both 1.0. In the left fundus there was multiple cotton wool spots, retinal hemorrhages and macular edema. At 15 days after accident, multiple cotton wool spots and retinal hemorrhages still be seen. Fluorescein angiography showed capillary nonperfusions and blocked fluorescence by retinal hemorrhages in the arteriovenous phase, leakage of dye in the region of capillary nonperfusion in the late venous phase. At 58 days after accident, multiple cotton wool spots remarkably decreased, however vision remained as 0.2. At 78 days after accident, left eye vision improved to 0.5. CONCLUSIONS: This case suggested to consider a safety belt injury as the cause of Purtscher's retinopathy.
