Purpose: To elucidate the clinical characteristics of secondary glaucoma associated with subluxation of the crystalline lens.
Setting: Department of Ophthalmology and Visual Sciences, Kyoto University Graduate School of Medicine, Kyoto, and Department of Ophthalmology, Tenri Hospital, Nara, Japan.
Methods: This retrospective study comprised 14 eyes of 13 patients with uncontrolled intraocular pressure (IOP) and lens subluxation. The subluxated lens was extracted through surgery.
Results: Angle closure caused by the subluxated lens was complicated in 3 eyes. In the remaining 11 eyes, uncontrolled IOP elevation was found despite the presence of deep anterior chambers and wide open angles. A mean of 14.1 months +/- 13.7 (SD) after cataract surgery, IOP was well controlled (lower than 21 mm Hg) in all 14 eyes. Mean IOP was 15.4 +/- 2.2 mm Hg at the final examination. Complications included transient vitreous hemorrhage in 5 eyes, choroidal detachment in 2 eyes, and retinal tears in 1 eye.
Conclusion: Lens extraction surgery was effective in controlling IOP in eyes with secondary glaucoma associated with lens subluxation.
