Corneal transplantation was most frequently observed among patients who previously underwent both trabeculectomy and tube shunt (5.00%, n = 672), followed by isolated tube shunt (2.97%, n = 3473) and isolated trabeculectomy (0.80%, n = 929). Eyes that only underwent tube shunts had a mean time to corneal transplantation of 2.49 years (standard deviation [SD], 2.4), compared with 3.75 years (SD, 3.3) for isolated trabeculectomy eyes and 3.21 years (SD, 2.6) for eyes that received both trabeculectomy and tube shunt. Adjusted likelihood of corneal transplantation was highest with both trabeculectomy and tube shunt (hazard ratio [HR], 5.88; 95% CI, 5.34–6.48), and isolated tube shunt (HR, 3.97; 95% CI, 3.69–4.26), compared with isolated trabeculectomy.</div></div><div><h3>Conclusions</h3><div>The likelihood of corneal transplantation is over 4 times higher after tube shunts compared with trabeculectomies. This may reflect factors such as chronic, cumulative corneal endothelial mechanical trauma from the tube shunt, changes to aqueous humor fluid circulation, altered aqueous humor composition and associated signaling pathways, differences in use of antimetabolites as adjunctive therapy, tube material, and tube movement or migration over time. Further research is needed to understand causes of corneal compromise, and consideration of corneal health is warranted in glaucoma surgical decision-making.</div></div><div><h3>Financial Disclosure(s)</h3><div>Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article.</div></div>","PeriodicalId":19519,"journal":{"name":"Ophthalmology.

The frequency of occurrence of initial defects was significantly higher than repeatable defects for the majority of patterns. The frequency of nasal step defects decreased as MD worsened, with a corresponding increase in the frequency of arcuate defects. There was a consistently higher frequency of bundle and nonbundle defects in unreliable versus reliable tests based on a false-positive rate above 15%, including an inferior enlarged blind spot (30.0% vs. 20.8%, <em>P</em> < 0.001), superior central defect (13.7% vs. 5.5%, <em>P</em> < 0.001), and partial superonasal quadrant (14.4% vs. 7.2%, <em>P</em> < 0.001) defects.</div></div><div><h3>Conclusions</h3><div>In a large cohort of suspect and early glaucoma, the most common VF defects were nasal step, enlarged blind spot and arcuate defects, with a significant difference in distribution between initial versus repeatable defects and reliable versus unreliable tests.
