A CASE OF MALIGNANT GLAUCOMA AFTER IMMEDIATE CATARACT SURGERY (SICS) FOR MATURE CATARACT

Malignant glaucoma is characterized by ciliary block or aqueous misdirection, shallowing of the anterior chamber with elevated intraocular pressure (IOP), resistance to treatment, and rapid progression to blindness. However, the exact pathogenic mechanism is yet to be established. Here, we report a case of malignant glaucoma caused by immediate primary Small Incision Cataract Surgery (SICS) for Senile Mature Cataract (SMC). A 63-year-old man, who had experienced blurred vision in both eyes (right more than left), had cataracts in both eyes. The right eye IOP was 15 mmHg, preoperative anterior chamber depth was 3.00 mm, and the axial length was 22.56 mm. We diagnosed SMC in the right eye and performed Small Incision Cataract Surgery (SICS). On postoperative day one, the IOP increased to 52 mmHg, the anterior chamber was shallow, and the angle was closed. After examining the patient, we diagnosed the patient with malignant glaucoma, performed hyaloid-zonulo-iridectomy, and administered mydriatics and steroid eye drops postoperatively. As a result, the IOP was limited to a 15-mmHg range with an open angle and deep anterior chamber. Malignant glaucoma can be caused by immediate primary Small Incision Cataract Surgery (SICS) for Senile Mature Cataract (SMC).
