Glaucoma secondary to pars plana lensectomy for congenital cataract

Abstract

Our results show the importance of careful follow-up of intraocular pressure after pars plana lensectomy for congenital cataract, especially when microcornea (or microphthalmos) is present.

Age at the time of cataract surgery and relative risk for aphakic glaucoma in nontraumatic infantile cataract

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] Among the various risk factors that have been reported, microcornea and cataract surgery at less than 9 months of age are perhaps the most significant. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] Some authors have concluded that cataract surgery at any age before 9 months of life confers the same risk for later aphakic glaucoma, whereas others have described specific times during infancy of greater risk for glaucoma development. A previous study from our institution did not find a specific age at surgery before 9 months that conferred less risk for aphakic glaucoma; however, many infant eyes in that series also had microcornea (horizontal corneal diameter #10 mm), a potentially confounding risk factor.…”

“…That study, however, also included cases with other structural anterior segment abnormality and had an average follow-up of only 2.85 years AE 1.9 years-a short follow-up, considering that most aphakic glaucoma is diagnosed 4-6 years after surgery. [1][2][3][4][5][6][7][8][9][10][11][12] There are at least 3 population-based studies in the literature regarding age of cataract surgery and later risk for aphakic glaucoma-from Sweden (Magnusson et al), 5 the United Kingdom (Chak et al), 12 and Denmark (Haargaard et al). 18 Magnusson and colleagues 5 found the greatest risk in the first 10 days of life but did not exclude the potentially confounding risk factor of persistent fetal vasculature (or microcornea) in their series.…”

Incidence and Risk Factors for Glaucoma After Pediatric Cataract Surgery With and Without Intraocular Lens Implantation

“…These conditions are reported risk factors for the development of aphakic glaucoma. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] We speculate that selection bias may explain the reduction in our incidence of glaucoma in patients after IOL implantation because we were not implanting IOLs in the eyes of patients at that time who were at risk for the development of glaucoma. We wondered whether our more-recent use of IOLs in these higher-risk patients was followed by a higher incidence of postcataract surgery glaucoma.…”

Cataract surgery for congenital cataract: Endothelial cell characteristics, corneal thickness, and impact on intraocular pressure

“…[4][5][6] The risk of glaucoma among aphakic children has been demonstrated to be as high as 32% in previous studies. [7][8][9] However, the diagnosis of glaucoma in these reports has rested primarily on intraocular pressure (IOP) measurement 7,10 and increasing evidence has suggested that IOP may be influenced by central corneal thickness (CCT). [11][12][13][14][15] In practice, we have encountered numerous patients who underwent surgery for congenital cataract and had elevated IOP without any other signs suggesting glaucoma.…”
