Case Report:
We present the case of a patient who was initially diagnosed of hypertensive uveitis with marked fluctuation that was resistant to the common treatment. After a systematic examination, retinal detachment of the ora serrata in the inferotemporal quadrant was diagnosed. The sample of aqueous humor showed melanic pigment and degenerated photoreceptor outer segments. After retinal detachment surgery, the intraocular pressure returned to normal levels without antiglaucoma medication.
Discussion:
The presence of photoreceptor outer segments in aqueous humor confirms the diagnosis of Schwartz-Matsuo syndrome, which should be considered as a differential diagnosis of iritis and glaucoma.
