We evaluated the clinical use of the Topcon CT10 non-contact tonometer in our outpatient clinic. Compared to the Goldmann applanation it is useful and reliable in screening glaucoma patients.

A description is given of a new family with X-linked cone dystrophy. A survey is also given of the findings in X-linked cone dystrophy. When an eye specialist sees a male patient with myopia and reduced visual acuity, the cause of which is not clear from the fundus picture, an X-linked cone dystrophy should be considered. Electrophysiological examination, combined with detailed testing of colour vision, can provide an explanation of the poor vision which satisfies both the patient and the ophthalmologist.

PurposeTo compare the visual performance and optical quality after Raindrop Near Vision Inlay implantation or monovision LASIK for the correction of presbyopia.Materials and methodsIn this retrospective case-series study, patients previously treated in the nondominant eye with monovision LASIK were compared with patients previously implanted with Raindrop Near Vision Inlay. The study enrolled 16 inlay and 15 monovision LASIK patients. Uncorrected near visual acuity, uncorrected distance visual acuity, binocular stereopsis, patient satisfaction, and patient task performance were assessed.ResultsPostoperatively, the mean spherical equivalent was −0.66 D (0.78 SD) for the inlay group and −1.03 D (0.56 SD) for the monovision LASIK group. Monocularly, at uncorrected near distances, 60% of inlay patients and 47% of monovision LASIK patients achieved ≥20/20. Monocularly, at uncorrected far distances, 75% of inlay patients and 40% of monovision LASIK patients achieved ≥20/32 vision. Binocularly, at near distances, 79% of inlay patients and 53% of monovision LASIK patients obtained ≥20/20 vision. All patients achieved ≥20/20 binocularly for distance. On average, inlay patients obtained 98 seconds of arc and monovision LASIK patients obtained 286 seconds of arc for stereopsis. Most (79%) of the inlay patients and 66% of monovision LASIK patients were satisfied with their near vision, while 86% of inlay patients and 67% of monovision LASIK patients were satisfied with their distance vision.ConclusionPatients receiving corneal inlays demonstrated better near and distance visual acuities, binocular stereopsis, task performance, and satisfaction, when compared to patients treated with monovision LASIK.

The effectiveness of intravitreal thrombin infusion during vitrectomy was prospectively evaluated in eight diabetic patients with persistent vitreous hemorrhages and severe proliferative vitreoretinopathy. A concentration of 80 units/ml of human thrombin diluted in BSS-plus infusion fluid was used. Bleeding time ranged between 2 and 15 seconds (mean, 5 seconds). The reduction of bleeding facilitated surgery. In five of the eight cases the vitreous was clear one day postoperatively. One month postoperatively six eyes had clear media. No additional postoperative intraocular inflammation developed. These results suggest that human thrombin causes less inflammation than bovine thrombin.
