AIM: To study the effectiveness of viscocanalostomy in patients with primary congenital glaucoma of the isolated trabecular dysgenesis category and compare it with trabeculotomy ab externo. METHODS: Eight patients with bilateral primary congenital glaucoma were enrolled in the study. After establishing the diagnosis, the more severely affected eye was randomly selected to undergo either trabeculotomy ab externo or viscocanalostomy, whereas the second eye underwent the other surgery 2 weeks after the first. The patients were examined on day 1, week 1, week 4 and thereafter every 4 weeks. Intraocular pressure (IOP) and corneal diameter measurements were obtained at week 1, month 6 and at the last reported follow-up. The paired-sample's Student's t test was applied for statistical analysis. RESULTS: The mean (standard deviation (SD)) follow-up period was 12.5 (1.86) months. Preoperative IOP of eyes undergoing trabeculotomy (34.0 (2.6) mm Hg) and that of eyes undergoing viscocanalostomy (32.3 (4.1) mm Hg) showed no significant difference (p>0.1). A drop in IOP was noted in both groups at week 1, month 6 and at the last follow-up visit (p<0.001). Similarly, a decrease in the postoperative vertical and horizontal corneal diameters was noted in the two study groups. CONCLUSION: Viscocanalostomy proved to be as effective as trabeculotomy ab externo in lowering IOP. Moreover, it is likely to be a good surgical alternative with a higher long-term success rate in eyes with more aggressive disease.

BACKGROUND: The presentation of microcornea associated with axial myopia by means of modern examination techniques. METHODS: Clinical investigations. RESULTS: The horizontal diameter of the cornea was 8.00 mm on both sides. The average refractive power of the cornea was 39.27D/38.48D on the right/left sides by corneal topography. The central corneal thickness was 568 micro m/559 micro m on the right and left sides, respectively. The depth of the anterior chamber was 1.18 mm/1.14 mm and the origin of the irises was steep, as demonstrated by ultrasound biomicroscopy (UBM). The axial length was 26.42 mm/25.63 mm on the right/left sides. Endothelial morphology disclosed degeneration on both sides. CONCLUSIONS: The present case demonstrates that the clinical signs of microcornea are flat corneal surface, normal thickness, and degenerated endothelium. This disorder associated with axial myopia is an extremely rare ophthalmologic condition.
