Site of trabeculectomy and control of intraocular pressure: a preliminary report
Abstract
Background/Objective: To determine the extent to which the site of trabeculectomy affects the extent of drop in intraocular pressure in an African population.
Methods: A prospective study involving 54 eyes randomly allocated to a nasal, central and temporal trabeculectomy group and followed up for a period of six months.
Results: The nasal group had consistently lower intraocular pressures though there was no statistically significant difference between the groups. A good number of patients were lost to follow up.
Conclusion: Surgeons performing primary trabeculectomy should consider the nasal site leaving the easily accessible temporal and central sites for repeat trabeculectomies when the need arises.
Key Words: Trabeculectomy, intraocular pressure, site, control
