Abstract Purpose:Multiple complications arising after trabeculectomy must be individually addressed. Here, we report a case in which excessive postoperative filtration for exfoliated glaucoma led to anterior chamber collapse and development of a milky-white pupillary opacity within a few hours, obscuring the fundus.

Case report:An 84-year-old woman underwent trabeculectomy of the right eye for exfoliation glaucoma. Intraocular lens dislocation and inferior displacement were observed preoperatively. On postoperative day 12, the patient presented with eye pain and decreased visual acuity. The anterior chamber of the right eye was absent. After approximately 5h, the pupil was filled with a milky-white opacity, and the intraocular lens and fundus were not visible. No filtration bleb clouding, increased conjunctival injection around the filtration bleb, or anterior chamber hypopyon was noted. Suspected infectious endophthalmitis led to reoperation. The cloudy material in the pupil was accompanied by a fibrin membrane that strongly adhered to the iris around the pupil. Clouding was noted posterior to the intraocular lens, prompting vitrectomy and antibiotic therapy. Postoperatively, the anterior chamber was formed, and the opacity did not recur.

Conclusion:We encountered a case of severely shallow anterior chamber due to anterior displacement of the intraocular lens following trabeculectomy. Because an anterior chamber abscess may not be observable if the anterior chamber is absent, caution is necessary if postoperative infection is suspected.
