Visual improvement could not be obtained for a long period after removing submacular hard exudates in most of the patients, suggesting that diabetic maculopathy should be treated before massive exudate deposits appear in the macula.

* PURPOSE: To evaluate the effect of vitrectomy on postoperative refraction after simultaneous vitrectomy and cataract surgery. * METHODS: We compared the spread between predicted and actual refractions in 206 eyes after a simultaneous vitrectomy, phacoemulsification, aspiration and acrylic lens insertion (combined surgery group), and in 67 eyes after cataract surgery only (cataract surgery group) as control. A vitrectomy was performed for diabetic retinopathy in 127 eyes, macular hole in 32 eyes, rhegmatogenous retinal detachment in 16 eyes, branch retinal vein occlusion in 15 eyes, and other conditions in 26 eyes. In the combined surgery group, 79 eyes had a gas tamponade after insertion of the intraocular lens. * RESULTS: The spread between predicted and actual refractions was -0.05 - 1.18 diopters (average ± SD) in the combined surgery group and +0.55 ± 1.32 D in the cataract surgery group. The actual refractive errors in the combined surgery group were found to shift toward myopia when compared with the controls. Among the combined surgery group, 127 eyes without a gas tamponade showed a postoperative refractive error of +0. 14 ± 1.11 D, while 79 eyes with a gas tamponade demonstrated an error of -0.36 ± 1.22 D. * CONCLUSIONS: Use of a gas tamponade in the combined surgery group increased the myopic change and was thought to have pressed the intraocular lens forward.

Purpose. The purpose of this study is to elucidate the clinicopathological features of dacryolithiasis and prevalence of associated infection in Japanese patients. Materials and Methods. Out of 13,471 outclinic patients from 2006 to 2011, 268 patients were scheduled to be performed dacryocystorhinostomy (DCR) due to dacryocystitis with nasolacrimal duct obstruction. Actually 266 patients underwent dacryocystorhinostomy (DCR) and two patients were cured by only ophthalmic examination. Dacryoliths were found in 17 cases (6.3%). Among 17 cases of dacryolithiasis, three patients were male, and 14 were female. The age of the patients ranged from 32 to 82 (mean 67) years, and 13 cases (76%) were more than 65 years of age. Pathological examination disclosed the infectious agents in 9 cases (53%), and all patients with infection were more than 65 years of age. Special stains revealed colonies of fungus, suspicious of Aspergillus, in 6 cases and gram-positive rods, and suspicious of Actinomyces, in 3 cases. Conclusions. The current study showed the frequent association of infection with dacryolithiasis in aged Japanese patients. This should be taken into the consideration for the treatment of dacryolithiasis.
