Secondary glaucoma associated with crystalline lens subluxation.

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.
