Angle Closure Glaucoma After Scleral Buckling for Retinopathy of Prematurity

Anterior Chamber Angle and Anterior Segment Structure of Eyes in Children With Early Stages of Retinopathy of Prematurity

“…29 Acute-onset angle-closure glaucoma most commonly occurs in infancy or early childhood following laser photocoagulation, vitrectomy, or scleral buckle. 10,11,30,31 Several explanations may account for the development of angle closure. Laser thermal injury to the choroidal vasculature may contribute to vessel congestion and subsequent posterior pushing on the lens-iris diaphragm.…”

“…Angle-closure glaucoma can occur in ROP patients after diode laser treatment or scleral buckling. [9][10][11] The choroidal congestion and anterior rotation of the ciliary body displace the lens-iris diaphragm forward and cause the anterior chamber angle to become narrow. Even in cases of regressed ROP, angle-closure glaucoma may occur in adulthood, and relative anterior microphthalmos is a typical finding.…”

Angle closure in younger patients

“…75,76 Angle closure has also been reported to occur after diode laser treatment for the retinopathy 77 and after scleral buckling. 6 Angle closure may occur in very young children with ROP due to anterior displacement of the lens-iris diaphragm.…”

“…Angle closure is rare in children and young adults, only isolated cases and small series, primarily composed of particular entities, having been reported. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] The purpose of this study was to evaluate the demographics and clinical information for all patients in our database with angle closure who were 40 years old or younger.…”

“…Various mechanisms for the development of glaucoma in eyes with ROP have been proposed. These include, forward displacement of lens iris diaphragm with progressive or acute angle closure in eyes with cicatricial ROP [7,8], neovascular glaucoma, glaucoma following vitreoretinal (VR) surgery, cilio-lenticular block glaucoma [9] and arrest or delay in angle development [10]. Laser for ROP can rarely be associated with recurrent hyphema or elevated IOP secondary to angle closure, which may resolve without long-term sequelae or may need intervention [11,12].…”
