Case Report: We report the case of a 29-year-old man who underwent Ahmed valve implantation in both eyes as treatment for uveitic glaucoma, subsequently presenting with bilateral ocular decompression retinopathy in the postoperative period. Discussion: Ocular decompression retinopathy is a rare complication of filtering surgery in patients with glaucoma; however, the course is benign in most cases, with spontaneous resolution of bleedings and improvement of visual acuity.

BackgroundClassic retinitis pigmentosa (RP) and other syndromic variants have previously been associated to Fuchs’ heterochromic iridocyclitis (FHI). Common immunogenic and inflammatory pathways have been proposed to explain the higher incidence of this uveitic phenomenon in patients with retinal dystrophies without definitive answers. Infrequent variants of RP such as inverse RP have not been previously reported in association with FHI. We believe that finding the way these entities connect can shed some light into their complex pathogenesis and help find ways to foresee and prevent the appearance of complications such as cataract and macular edema.Case presentationWe present a 15 year old mexican male with history of nyctalopia and rapid, progressive visual loss since infancy who had profound hyper and hypopigmented retinal pigment epithelium changes in the posterior pole together with pigment clumping in the macula of both eyes and an electroretinogram pattern consistent of rod-cone dystrophy. He was diagnosed with inverse RP. Three years after his first visit he was found to have a mild asymptomatic non granulomatous anterior uveitis in the right eye with fine stellate keratic precipitates and subtle iris stromal atrophy not associated with iris synechiae and without evidence of posterior uveitis or findings consistent with infectious etiology. Findings were consistent with FHI. As the patient was normotensive, the lens was transparent and there was no clinical evidence of macular edema, the patient was kept under observation without treatment.ConclusionsPatients with RP are prone to develop chronic, low grade inflammation responses similar to the ones present in FHI. This association makes us believe that immunogenetic pathways involved in the degenerative process that leads to photoreceptor loss may become a target in the prevention and treatment of inflammatory complications in RP and disease progression. It also suggests FHI may be a triggered response predisposed by an unidentified genetic factor that may be related to genes affected in RP and thus be identified before irreversible complications such as glaucoma occur.

Fallbericht: Vorgestellt wird der Fall eines 29-jährigen Mannes, der nach Implantation einer Ahmed-Drainage in beiden Augen zur Behandlung eines uveitischen Glaukoms postoperativ eine bilaterale okuläre Dekompressionretinopathie entwickelte. Diskussion: Die okuläre Dekompressionsretinopathie ist eine seltene Komplikation der filtrierenden Glaukomchirurgie; sie verläuft jedoch meist gutartig, die Blutungen bilden sich spontan zurück und es kommt zu einer Erholung der Sehschärfe.

Purpose: To report a case and management of persistent hypotony with hypotony-induced maculopathy after CyPass® device implant. Background: The CyPass® was the first supraciliary ab interno device approved by FDA and commercially available. Efficacy studies showed adequate intraocular pressure (IOP)-lowering results in combination with phacoemulsification. Hypotony induced by suprachoroidal minimally invasive glaucoma surgery (MIGS) was reported to be lower than 3% in the population that comprised the COMPASS study. Case description: A 57-year-old female patient with mild open-angle glaucoma with maximum topical medical therapy who underwent sequential bilateral CyPass® implantation developed persistent hypotony. Device obstruction was induced through argon laser burns directed to the peripheral iris, and the device was no longer visible on follow-up examinations. Topical IOP-lowering medication was restarted (timololdorzolamide) and has since been controlled under 16 mm Hg, without progression on visual fields. Conclusion: Argon laser burns directed to the peripheral iris to induce synechiae development that produces device obstruction are an effective technique to manage persistent hypotony after supraciliary CyPass® implantation. Clinical significance: Here, authors show a novel approach for treatment of persistent hypotony secondary to CyPass® implantation. In the knowledge of the authors, this is the first report that describes a noninvasive management for this complication, and this case could help other physicians to manage similar cases.
