To evaluate the efficacy of the Ahmed valve implant in patients with uncontrolled uveitic glaucoma, the medical records of all patients with uncontrolled uveitic glaucoma who underwent Ahmed valve implant surgery between October 1993 and March 1996 were reviewed. Surgery was considered a success if intraocular pressure (IOP) was less than 22 mmHg and greater than 4 mmHg (with or without antiglaucoma medications) at the last postoperative visit. It was not a success when further glaucoma surgery had been performed, or chronic hypotony, phthisis, or loss of light perception occurred. Fourteen patients (14 eyes) with a mean age of 45.7 years were included. Most of them were high-risk patients, many of whom had already had cataract surgery (71.4%) and undergone one to three previous glaucoma surgeries (57.1%). Follow-up for eyes in which IOP was controlled ranged from 11 to 40 months (mean 22.6 months). Success was achieved in eight of 14 eyes (57.14%). Intraocular pressure was reduced from a mean of 32.64 +/- 7.79 mmHg (range 23-46 mmHg) with 2.78 +/- 0.57 antiglaucoma medications (range 2-4) preoperatively to 17.57 +/- 10.93 mmHg (range 0-38 mmHg) (p < 0.0001) with 0.71 +/- 0.99 antiglaucoma medications (range 0-3) postoperatively (p < 0.0001). The most common complications were encapsulated bleb in six eyes (42.8%), transient hypotony in six eyes (42.8%), and hyphema in three (21.4%). Ahmed valve implant appeared to be a safe alternative in high-risk patients with uncontrolled uveitic glaucoma who have had multiple previous ocular surgeries.

CPP in the Mexican population is more frequent in males and usually presents in patients less than 14 years of age. It is typically bilateral, and the most common symptom is decreased visual acuity. The most important clinical findings are located in the vitreous and retina. Cataract and cystoid macular edema are the most frequent complications. Treatment comprises periocular and systemic corticosteroids or other immunosuppressive drugs.

The more common clinical features in this group of patients were fine and stellate keratic precipitates, atrophy of the iris crypts, and iris nodules. Clinically evident iris heterochromia was present in only 25% of the affected eyes. FHI diagnosis in brown-eyed patients cannot rely on iris heterochromy only.

A higher frequency of oral symptoms and parotid enlargement and stronger B cell activity (autoantibody production and lymphocyte infiltration) were observed in pSS. Whether these results reflect a true difference between the 2 disease entities or derive from underlying variables remains uncertain.

RTX is useful in the treatment of refractory necrotising scleritis in patients with GPA. Of note, in those who relapse after remission, RTX can be successfully used for retreatment.
