ABSTRACT
This study was performed to evaluate optic disc appearance, retinal nerve fiber layer (RNFL) thickness, and macular thickness in normal, ocular hypertensive (OHT) and glaucomatous eyes using optical coherence tomography (OCT) 3000. One hundred fifty-eight eyes of 167 consecutive subjects were enrolled: 60 normal, 53 OHT, and 54 glaucomatous. OCT topographic parameters of cup diameter, cup area, rim area, and cup/disc area ratio were significantly less in OHT eyes than in normal eyes and were significantly less in glaucomatous eyes than in normal and OHT eyes. RNFL was significantly thinner in OHT eyes than in normal eyes in the inferior quadrant, and in glaucomatous eyes than in OHT and normal eyes in the mean and for all four quadrants. Macular thickness was significantly thinner in glaucomatous eyes than in OHT and normal eyes throughout all subdivisions. Optic disc parameters, and RNFL and macular thickness measurements made with OCT may be useful in the clinical assessment of glaucoma.

PURPOSE: To evaluate the effectiveness of using Keratome in endonasal Dacryocystorhinostomy (DCR). METHODS: The authors used 3.0mm keratome, designed for cataract surgery, to incise medial wall of the lacrimal sac during endoscopic endonasal DCR in 11 patients with nasolacrimal duct obstruction. RESULTS: Surgical success rate was 90% with fast recovery time of nasal mucosa without specific complication. CONCLUSIONS: Lacrimal sac incision using keratome was more effective and non-invasive than using nasal forceps, with advantages such as shorter operation time and less nasal mucosa injury with rapid recovery time.
