“…In the TASS case,the etiology and toxic substances were not found. TASS often occurs after cataract surgery [11,12] , it also developed after other ocular surgeries such as keratoplasty [13] ,ICL implantation [14] , Trabeculectomy [15] , pterygium surgery [16] and posterior segment surgeries [17] .…”

Background To report a rare case of severe toxic anterior segment syndrome with ocular hypotony after uneventful cataract surgery. Case presentation Toxic anterior segment syndrome (TASS) is an infrequent complication of ocular surgery.Here,we reported a rare TASS case with ocularhypotony after uneventful cataract surgery.A 62-year-old male was presented to our clinic for blurred vision in the right eye.The patient was diagnosed with age-related cataract and the phacoemulsification and intraocular lens implantation was performed uneventfully in the right eye.On the first postoperative day,the diffuse cornea edema and dilated pupil were present in the right eye with a tentative diagnosis of TASS.The medication administration was inffective in the case.The patient developed corneal decompensation 1 year after cataract surgery.Given the resulting corneal edema, the patient underwent Penetrating keratoplasty (PKP),fibrin membrane removal and goniosynechialysis were performed simultaneously.Ocularhypotony developed unexpectedly 2 weeks after PKP and maintained steadily in the case.Ultrasound biomicroscopy (UBM)showed the ciliary body atrophy.Optical coherence tomography (OCT)showed chorioretinal folds caused by hypotony maculopathy after PKP.To the best of our knowledge, we first reported the TASS case with ocularhypotony. Conclusions In the TASS case,the ocular hypotony was thought to be due to severe atrophy of ciliary body caused by uncertain toxic substance.

Toxic anterior segment syndrome (TASS) is an acute, sterile, postoperative inflammatory reaction of the anterior segment without vitreous involvement, following an uncomplicated and uneventful ocular surgery, having broad and multiple etiologies. The symptoms of decreased visual acuity and ocular discomfort generally occur within the first 12–48 h after intraocular surgery. The clinical signs include prominent limbus-to-limbus corneal edema, anterior chamber cells, aqueous flare, fibrinous inflammation, and/or keratic precipitates. There can be sight-threatening complications of TASS, such as permanent corneal decompensation, intractable glaucoma, and cystoid macular edema. The causes of TASS are emerging and being reported, so are the newer treatment options for managing the inflammation and its complications. Prevention guidelines for TASS are being updated, and a traceability system for surgical instruments and intraocular fluids used during the surgery is being perpetually developed. It is important to recognize TASS and start treatment on an immediate effect. Hereby, we review the literature on TASS, emphasizing its etiology, pathophysiology, management, prognosis, complications, and the importance of prevention as well as prompt recognition.
