Subjects and methods: This retrospective study was conducted at a tertiary eye care centre in North India and studied 33 eyes of 33 patients ( with previously operated trabeculectomy), who underwent phacoemulsification. Trypan blue dye (0.06%) was used to stain the anterior capsule. After completion of phacoemulsification, the staining of the trabeculectomy bleb was noted as diffuse, patchy, minimal or no staining. Results: Of the 33 eyes, 13 had diffuse staining (39.4%, mean IOP = 9.3 \u00b1 2.2 mm Hg), 7 (21.2%, mean IOP= 15.5 \u00b1 1.8 mm Hg) had patchy staining, 4 had minimal staining (12.1%, mean IOP= 17.5 \u00b1 0.5mm Hg) and nine (27.3%, mean IOP= 19.3 \u00b1 1.6 mm Hg) had no staining. These staining patterns were labeled as groups 1 - 4 respectively. Statistical analysis showed that the difference between the IOPs in Group 1 - 2 and between Group 2 - 3 was not significant statistically (p=0.682 and 0.665 respectively). However the differences between the IOPs between Groups 1 - 3, 1 - 4, 2 - 4, and 3 - 4 were found to be highly significant statistically (p&lt;0.0005).Conclusions: Trypan blue dye can be used to test the amount of sub-conjunctival filtration in eyes undergoing phacoemulsification cataract surgery.DOI:\u00a0http:\/\/dx.doi.org\/10.3126\/nepjoph.v4i2.6536  Nepal J Ophthalmol 2012; 4 (2): 224-229 \u00a0<\/jats:p>","DOI":"10.3126\/nepjoph.v4i2.6536","type":"journal-article","created":{"date-parts":[[2012,7,30]],"date-time":"2012-07-30T05:34:44Z","timestamp":1343626484000},"page":"224-229","source":"Crossref","is-referenced-by-count":6,"title":["Trypan blue staining of filtering bleb in eyes with operated trabeculectomy"],"prefix":"10.3126","volume":"4","author":[{"given":"T","family":"Dada","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S J","family":"Bali","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S","family":"Mohan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S","family":"Bhartiya","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A","family":"Sobti","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A","family":"Panda","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1670","published-online":{"date-parts":[[2012,7,25]]},"container-title":["Nepalese Journal of Ophthalmology"],"original-title":[],"link":[{"URL":"https:\/\/www.nepjol.info\/index.php\/NEPJOPH\/article\/download\/6536\/5325","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.nepjol.info\/index.php\/NEPJOPH\/article\/download\/6536\/5325","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2018,12,28]],"date-time":"2018-12-28T12:02:07Z","timestamp":1545998527000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.nepjol.info\/index.php\/NEPJOPH\/article\/view\/6536"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,7,25]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2012,7,30]]}},"URL":"https:\/\/doi.org\/10.3126\/nepjoph.v4i2.6536","relation":{},"ISSN":["2091-0320","2072-6805"],"issn-type":[{"type":"electronic","value":"2091-0320"},{"type":"print","value":"2072-6805"}],"subject":[],"published":{"date-parts":[[2012,7,25]]}}}
