The secondary aim is to identify associated factors for visual decline or loss, highlighting differences between neonatal and infantile subgroups.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>The medical records of pediatric glaucoma patients from 1996 to 2017 at the University Hospital of Verona (Verona,\u00a0Italy) were retrospectively reviewed. Visual acuities, surgeries, PCG subtype and etiology of vision impairment were recorded. Statistical analyses were performed to detect factors associated with vision decline.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Sixty-seven eyes (40 patients) were included in the study. Developmental predictive curves of visual acuity showed that children with infantile PCG had a better visual outcome than children with neonatal PCG at each step of follow-up. A good-to-moderate VA (&lt;\u20091 LogMAR) was achieved in 56 eyes (83.6%), while 11 eyes (16.4%) had poor VA (\u2265\u20091 LogMAR). The age at onset, sex, number of surgeries, intraocular pressure (IOP) control (with or without antiglaucoma drugs), axial length (AL) and corneal opacities were statistically associated with vision impairment (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01). The main cause of visual impairment was amblyopia.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Visual outcomes of PCG significantly correlate with the age at diagnosis. Although a good long-term IOP control can often be achieved in PCG, often the visual acuity remains below the lower limits of the normal range. Poor vision in childhood is related to global developmental problems, and referral to third-level services should not be delayed to prevent vision impairment. In this regard, visual acuity curves can be a useful tool for the consultant ophthalmologist to define the visual development of children affected by PCG.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s10792-021-01957-0","type":"journal-article","created":{"date-parts":[[2021,7,23]],"date-time":"2021-07-23T11:04:27Z","timestamp":1627038267000},"page":"3861-3867","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Primary congenital glaucoma surgery: outcomes and visual function"],"prefix":"10.1007","volume":"41","author":[{"given":"Elena","family":"Gusson","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesca","family":"Chemello","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7619-3281","authenticated-orcid":false,"given":"Rosa","family":"Longo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elia","family":"Franzolin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberta","family":"Vesentini","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuseppe","family":"Verlato","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giorgio","family":"Marchini","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,7,23]]},"reference":[{"key":"1957_CR1","doi-asserted-by":"publisher","first-page":"382","DOI":"10.1016\/j.sjopt.2019.10.002","volume":"33","author":"AH Badawi","year":"2019","unstructured":"Badawi AH, Al-Muhaylib AA, Al Owaifeer AM, Al-Essa RS, Al-Shahwan SA (2019) Primary congenital glaucoma: An updated review.
