[A study on the treatment of secondary glaucoma due to intumescent senile cataract].

OBJECTIVE

To discuss surgical methods of treating secondary glaucoma due to intumescent senile cataract.

METHODS

Of 47 inpatient cases (49 eyes) who suffered from secondary glaucoma due to intumescent senile cataract, 28 cases (30 eyes) had been performed the following four different types of operation; (1) extracapsular cataract extraction (ECCE) and posterior chamber intraocular lens (PC-IOL) implantation with peripheral iridectomy, (2) ECCE and PC-IOL implantation with segmental iridectomy, (3) ECCE and PC-IOL implantation with trabeculectomy, and (4) five-combined-operation including scleral trephination, cyclodialysis, vitreous paracentesis, ECCE and PC-IOL implantation.

RESULTS

The corrected visual acuities in 28 eyes had improved, whereas that in 2 eyes did not improve because of optic nerve atrophy. All the intraocular pressure in 30 eyes was within normal limit, including 12 eyes topically using antiglaucoma drugs.

CONCLUSION

Most of patients with secondary glaucoma due to intumescent senile cataract can be cured surgically by iridectomy or trabeculectomy combined with ECCE and PC-IOL implantation. The five-combined-operation is an effective way to treat difficult cases such as long-term disease course, result with antiglaucoma drugs not satisfactory and swelling lens with flat anterior chamber.
