Tear Drainage through the Upper Can,liculus in Case of Lower Canalicular ObstruCtion

Symptomatic epiphora has been rarely observed in patients jwith only one canaliculus obstruction. The authors experienced 7 cases of only lower canahculus obstruction without epiphora. Tear drainge of these eyes was assessed using dacryoscintigraphy and compared with the comtrol eyes. The measurement of T1/2 valuse, the duration of which a given amount of 99m-Tc-phytate drops to half in the conjunctival fornix was performed. The T1/2 valuse was 368.1 seconds in average in the eye with the lower canaliculus obstruction and 263.3 seconds in the control eyes(p

Clinical Effecd of Endonasal Lacrimal Surgery

This study was carried out to compare the clinical effect of the endonasal lacrimal surgery done in 75 eyes of the 62 patients with that of the conventional lacrimal surgery done by the same operator in 72 eyes of the 57 patients. The diameter of intranasal ostium was 1.9 +/- 0.4 mm in endonasal approach and 2.6 +/- 1.4 mm in skin approach (p<0.05), respectively. Postoperative hospitalization were 1.7 - 2.5 days shorter in endonasal lacrimal surgery than those of conventional lacrimal surgery (p<0.001). Satisfactory tear drainge was observed in 29 eyes (90.6%) after endonasal dacryocystorhinostomy and in 28 eyes (90.3%) after conventional dacryocystorhinostomy, and 41 eyes (95.3%) revealed astisfactory tear drainge after endonasal conjunctivodacrystorhinostomy and 39 eyes (95.1%) showed good results after conventional conjunctivodacr yocystorhinostomy. In summary, endonasal lacrimal surgery showed no cutaneous scar, less edema and hematoma with short recovery time and similar success rate to the conventional lacrimal surgery. Thus, endonasal lacrimal surgery might be better than conventional lacrimal surgery.

Clinical Efficacy of Dermis-Fat Graft vs. Posterior Tenon's Capsule Suturing in Anophthalmic Orbit

The anatomic and physiologic changes of the anopthalmic orbit affect cosmetic appearance of the patient and function of the socket and the prosthesis. During the past three years, the authors studied 13 cases of dermis-fat graft and 27 cases of posterior Tenon's capsule suturing with a plastic implant, and compared the post'operative effects of the two procedures. Dermis-fat graft produced good fornix formation with no remarkable fat atrophy after both primary and secondary proceddure. Posterior Tenon's capsule suture technique showes good effect to keep implant from migration or extrusion. Size of the plastic implant and fixation of the extraocular muscles were important factors also for good cosmesis and implant motility. There revealed no significant difference between the two procedures in EOM motility, enophthalmos, deep superior sulcus deformity, implant migration or prolapse etc.
