Three Cases of Hypotonic Maculopathydue to Blunt Trauma, Treatedby 360-degree Scleral Buckling

Background: In hypotonic maculopathy with a shallowanterior chamber, it is difficult to delineate the extentof cyclodialysis. Reoperations are often reported, and amethod of management for hypotonic maculopathy is notyet established.Cases: We treated three patients with hypotonicmaculopathy due to blunt trauma. Case 1 did not improveafter two cryoablations, two cyclopexies, and a laserphotocoagulation treatment. Cases 2 and 3 did not im-prove after a single laser photocoagulation treatment.All cases exhibited retinal breaks, and underwent 360-degree scleral buckling.Results: In all cases, intraocular pressure was normalizedsoon after the surgery. We found that ultrasound biomi-croscopy (UBM) was helpful in clarifying cyclo-dialysis, and that optical coherence tomography (OCT)was useful to observe morphologic changes of the maculain detail.Conclusion: This procedure is considered to be usefulin the treatment of hypotonic maculopathy.

Surgical Treatment Complicatedby Dacryocystitis and Retinal Detachmentof a Patient with Wegener Granulomatosis

Background: We report surgical treatment of a patientwith dacryocystitis and retinal detachment (RD), whichare rare ophthalmic involvements of Wegener granu-lomatosis (WG).Case: The patient was a 26-year-old man with WG. Hewas diagnosed as having WG 4 years previously andhe had been treated by maintenance doses of predni-solone and cyclophosphamide. Rheumatoid factor andserum antinuclear antibody were negative. Cytoplasmicpattern-antineutrophil cytoplasmic antibody (C-ANCA)and renal function were normal. He was found to havenasolacrimal duct obstruction and lattice degenerationbilaterally, retinal tear with RD in the left eye and tearwithout RD in the right eye. No sign of vasculitis wasfound in fluorescein angiography. Bilateral dacryo-cystorhinostomy was performed without any sign ofpostoperative necrosis of the wound. After the surgery,epiphora and eye discharge disappeared and lacrimalpassage has been maintained without obstruction. Thepathological findings of his nasal mucosa and lacrimalsac showed chronic inflammation and no typical changesof WG. There was no abnormal change in the conjunctivaand sclera after an uncomplicated scleral bucklingsurgery.Conclusion: We conclude that operations such as da-cryocystorhinostomy and scleral buckling surgery maybe performed successfully when WG is controlled withinthe normal limits of C-ANCA.
