PURPOSE To observe the surgical effect of trabeculotomy for congenital glaucoma patients with axial length shorter than 23mm and corneal diameter smaller than 13mm.
METHODS Prospective observational study. Trabeculotomy was performed on congenital glaucoma patients with ocular axial length shorter than 23mm and corneal diameter smaller than 13mm. Cases were excluded when schlemm canal cannot be found or small hyphema not reaching the pupillary margin cannot be observed after schlemm canal was incised. All cases were followed up for 18 to 36 months. Main outcome items include intraocular pressure, corneal diameter and cup to disc ratio of optic nerve head.
RESULTS 13 eyes of 8 patients were enrolled in the study. Mean follow-up period was 27.69 months. All corneas recovered transparent after operation. There was no increase In cup to disc ratio of optic nerve head during following up. In eight cases, only one eye’s intraocular pressure was 23mmHg and failed to be controlled under 21 mmHg. The success rate was 92.3% at 18 months postoperatively.
CONCLUSION Following surgical indications strictly and performing operation correctly are critical for high long-term success rate of trabeculotomy for congenital glaucoma. |
