Abstract
PURPOSE To investigate the postoperative clinical outcomes and axial length (AL) growth of infants with congenital cataracts and microphthalmos following first-stage cataract surgery. DESIGN Retrospective case-control study. METHODS Setting: Single centre. Infants with congenital cataract that met the inclusion criteria were classified into two groups: the microphthalmos and comparison groups. All infants underwent a thorough ophthalmologic examination before surgery, and one week, 1 month, 3 months, and every 3 months after surgery. RESULTS This study enrolled 21 infants (42 eyes) in the microphthalmos group and 29 infants (58 eyes) in the comparison group. More glaucoma-related adverse events were observed in the microphthalmos group (7 eyes, 16.7%) than in the comparison group (0 eyes, 0%) (p < 0.001). At each subsequent follow-up, the comparison group had a greater AL than the microphthalmos group (all p < 0.001), and AL growth was significantly higher in the comparison group than in the microphthalmos group (all p = 0.035). Visual acuity improvement in the microphthalmos group was similar to that of the comparison group. CONCLUSION Early surgical intervention improves visual function in infants with congenital cataracts and microphthalmos although with a higher incidence of glaucoma-related adverse events. After cataract removal, the AL growth of microphthalmic eyes is slower than that of normally developed eyes.

Incidence of and risk factors for suspected and definitive glaucoma after bilateral congenital cataract surgery: a 5-year follow-up. Br J Ophthalmol 2024; 108:476-483. [PMID: 36828619 DOI: 10.1136/bjo-2022-322589] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Accepted: 02/08/2023] [Indexed: 02/26/2023]
Abstract
AIMS To report the incidence and associated risk factors for developing suspected and definitive glaucoma after bilateral congenital cataract (CC) removal with a 5-year follow-up. METHODS Secondary analysis of a prospective longitudinal cohort study. Bilateral CC patients who had undergone cataract surgery between January 2011 and December 2014 at Zhongshan Ophthalmic Centre were recruited. Suspected glaucoma was defined as persistent ocular hypertension requiring medical treatment. Definitive glaucoma was defined as accompanied by the progression of glaucomatous clinical features. According to postoperative lens status in 5 years follow-up: 130 eyes in the aphakia group; 219 in the primary intraocular lens (IOL) implantation group and 337 in the secondary IOL implantation group. The Kaplan-Meier survival and Cox regression analyses were used to explore the cumulative incidence and risk factors for suspected and definitive glaucoma. RESULTS Three hundred fifty-one children (686 eyes) with bilateral CCs were enrolled in the study. The mean age at surgery was 1.82±2.08 years, and the mean follow-up duration was 6.26±0.97 years. Suspected and definitive glaucoma developed at a mean time of 2.84±1.75 years (range 0.02-7.33 years) postoperatively. The cumulative incidence of suspected and definitive glaucoma was 9.97% (35 of 351 patients), including 6.12% (42 eyes) for definitive glaucoma and 2.48% (17 eyes) for suspected glaucoma. Microcornea (HR 4.103, p<0.0001), CC family history (HR 3.285, p=0.001) and initial anterior vitrectomy (HR 2.365 p=0.036) were risk factors for suspected and definitive glaucoma. Gender, age at surgery, intraocular surgery frequency, length of follow-up and frequency of neodymium-doped yttrium aluminumaluminium garnet laser were non-statistically significant. Primary IOL implantation was a protective factor (HR 0.378, p=0.007). CONCLUSIONS Identifying suspected and definitive glaucoma after bilateral CC surgery can lower the risk of secondary blindness in children. Patients with related risk factors need to pay more attention and thus reach early intervention and treatment during clinical practice. Primary IOL implantation may be a potential protective factor, need more clinical trials to be verified. TRIAL REGISTRATION NUMBER NCT04342052.

Am J Ophthalmol 2023; 245:61-69. [PMID: 36084681 DOI: 10.1016/j.ajo.2022.08.023] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2022] [Revised: 08/21/2022] [Accepted: 08/22/2022] [Indexed: 11/25/2022]
Abstract
PURPOSE We sought to compare the prediction accuracy of 6 intraocular lens (IOL) formulas, namely, the Haigis, Hoffer Q, Holladay I, SRK/T, Barrett Universal II and Hoffer QST formulas, in microphthalmic eyes, including those with nanophthalmos and relative anterior microphthalmos (RAM). DESIGN Retrospective case series. METHODS Twenty-six eyes with nanophthalmos (axial length [AL] 16.84 ± 1.36 mm, range 15.25 mm-19.82 mm) and 12 eyes with RAM (corneal diameter 8.41 ± 0.92 mm, range 7.00 mm-9.50 mm) receiving cataract surgery were included. The IOL Master 500 was used for biometry; thus, lens thickness (LT) was omitted in the IOL power calculation. The mean and median arithmetic and absolute prediction errors (PEs) of the 6 original calculation formulas, the absolute PEs of the 6 formulas after optimization, and the proportion of PEs within ±0.25 diopters (D), ±0.5 D, ±1 D, and ±2 D with each formula were compared. The factors influencing PE were analyzed by multivariate regression. RESULTS In the nanophthalmos group, the overall prediction results were shifted to myopia. The original Haigis formula had the smallest median absolute PE (1.61 D, P < 0.001), and the optimized Haigis formula had the highest proportion of PEs within ±0.25 D, ±0.5 D, and ±1 D. In the RAM group, the overall prediction results were not significantly different from 0 (P > .05). No significant difference was found among the formulas before optimization (P = .146) and after optimization (P = .161), but the optimized Barrett Universal II formula had the highest proportion of PEs within ±1 D and ±2 D. CONCLUSIONS When omitting the LT parameter in the calculation, the Haigis formula was the most accurate in cataract patients with nanophthalmos (AL <20 mm) among the 6 IOL calculation formulas, and the Barrett Universal II formula had the highest accuracy in cataract patients with RAM (corneal diameter ≤9.5 mm).

Abstract
To observe the ocular axis, visual acuity and intraocular pressure (IOP) of aphakic eye in infants with congenital cataract and complex microphthalmos after first-stage cataract surgery.This retrospective study included infants with congenital cataract and operated at the Qingdao Eye Hospital between January 2010 and December 2014. The infants were divided into 2 groups: preoperative axial length <18 mm (microphthalmos) or ≥18 mm (controls). Follow-up lasted 24 months; visual acuity, axial length, and IOP were evaluated.There were 28 infants (55 eyes) in the microphthalmos group and 35 (61 eyes) in the control group. The preoperative visual acuity was negative for optokinetic nystagmus, while the postoperative visual acuity was positive for optokinetic nystagmus in both groups. The growth rate was higher in the microphthalmos group (1.4 ± 0.8 vs 0.8 ± 0.4 mm/yr, P < .001 vs controls). The axial length was smaller in the microphthalmos group at all time points compared with the control group (all P < .001). There was no changes in IOP in the microphthalmos group from baseline to 24 months (P = .147), but the IOP was slightly decreased in the control group (P = .015).Cataract surgery may contribute to ocular axis growth in infants with complex microphthalmos.

Abstract
Background The goal of this study is to systematically evaluate the magnetic resonance imaging (MRI) signal characteristics and size of cataracts that may be encountered in pediatric and young adult patients. Methods A retrospective analysis of the MRI features with cataracts in a series of cases, including characterization of signal intensity on T2-weighted and T1-weighted sequences, as well as measuring the thickness of the lens. Results Among nine cataracts in seven patients, three lenses were thickened and hyperintense on T2-weighted sequences, presumably related to osmotic effects. The rest of the lenses were either normal in size and signal characteristics, such as in the cases of neurofibromatosis type 2 or small in cases of microphthalmos, with signal characteristics related to calcifications. Conclusions There are several different types of cataracts that can occur in pediatric and young adult patients, which may or may not be conspicuous on MRI. The findings in this study can serve as a guide for what abnormalities of the lens may be encountered on MRI.

Abstract
PURPOSE To evaluate the long-term incidence and risk of glaucoma after bilateral congenital cataract surgery in microphthalmic eyes. DESIGN Retrospective, observational case series. METHODS Subjects: Children with microphthalmic eyes who had undergone surgery for bilateral congenital cataract within 6 months of birth and been followed up for at least 5 years. PROCEDURES Review of medical records at our institution. MAIN OUTCOME MEASURES Probability of an eye's developing glaucoma after bilateral congenital cataract surgery and associated risk factors. RESULTS Thirty-eight eyes of 19 children with bilateral congenital cataract were included. The mean age at surgery was 3.2 ± 1.7 months, and the mean follow-up duration was 7.79 ± 2.61 years. After cataract surgery, 11 eyes (29.0%) developed glaucoma at the age of 4.0 ± 1.4 years. Three of these eyes underwent Ahmed glaucoma valve implantation surgery. The probability of an eye's developing glaucoma was estimated to be 32.0% by 10 years after surgery. In a multivariate analysis, axial length was significantly associated with glaucoma development (odds ratio = 0.364, P = .025). Age at the time of cataract surgery, corneal diameter, and aphakia did not affect the risk of glaucoma (P > .10). Eyes without glaucoma had a better final visual outcome than those with glaucoma (0.75 ± 0.60 and 1.47 ± 1.10 logMAR, respectively, P = .049). CONCLUSIONS The long-term cumulative risk of postoperative glaucoma development was 32.0% by 10 years after bilateral congenital cataract surgery. Because the risk of developing glaucoma persists for several years after surgery, careful monitoring and control of intraocular pressure is needed to preserve vision in such patients.

Abstract
PURPOSE To report the surgical outcomes of children with cataract associated with microphthalmia, microcornea, or persistent fetal vasculature (MMP) and children with isolated cataract. METHODS The study included 111 children (cataract associated with MMP: n = 25) who underwent cataract surgery at younger than 16 years. Exclusion criteria were duration of follow-up less than 5 years, intraindividual differences in age at surgery, eye disorders other than MMP, secondary cataract, and syndromal diseases. Main outcome measures were proportion of eyes with glaucoma and best corrected visual acuity (BCVA). Both groups were dichotomized by age at surgery (early intervention group: ≤ 48 days). Descriptive analysis was performed throughout. RESULTS Median age at surgery was 3.9 months for cataract associated with MMP and 23.3 months for isolated cataract. The median (interquartile range [IQR]) duration of follow-up was 95.9 months (range: 76.0 to 154.5 months). In children with bilateral cataract associated with MMP, the proportion of eyes with final BCVA worse than 0.3 logMAR was similar regardless of age at surgery (early intervention: 80%, later intervention: 78%). In bilateral isolated cataract, the proportions were 56% and 33%, respectively. Children with cataract associated with MMP had a high prevalence of glaucoma (28%). Glaucoma prevalence was lower in the later intervention group. CONCLUSIONS In the presence of MMP, early cataract surgery is associated with a high risk of post-lensectomy glaucoma, but does not offer the benefit of better visual outcomes.

Methods This cross-sectional study was conducted at Al-Ibrahim Eye Hospital, Karachi from January 2016 to August 2017. It included thirty micro ophthalmic eyes of infants with visually significant cataract of age less than two years who had cataract surgery without intraocular lens implantation. Axial length of globe was 19 mm or less in all thirty eyes of seventeen infants. in which thirteen infants had bilateral cataract and four had unilateral cataract. Result Thirty Simple Micro ophthalmic eyes from seventeen patients having visually significant congenital cataract were studied. Thirteen had bilateral cataract and four had unilateral cataract. Mean preoperative IOP was 9.0±1.2 mmHg and postoperative IOP after three months was 10.9±3.2 mmHg. Three patients had secondary capsular opacification 17.6%. Two patients had posterior synachae 11.8% after three months. Conclusion The results suggest that cataract surgery in simple microophthalmia is safe procedure. Postoperative complications in this study were within acceptable limits. Long term study with intraocular lens is required to confirm our observation.

Abstract
Background Aphakic glaucoma is a common complication after congenital cataract extraction, especially in those who have surgery during infancy. This case report describes a case of bilateral pupillary block glaucoma diagnosed with intraoperative ultrasound biomicroscopy (UBM) after removal of congenital cataract. Case presentation We present a case report of a 9-month-old infant with bilateral corneal enlargement and ocular hypertension after uneventful removal of congenital cataracts. Initial and follow-up examination findings were reviewed. The infant was suspected to have developmental glaucoma and schemed to have bilateral trabeculotomy until pupillary obstruction by vitreous herniation and angle closure with iris bombé were detected by intraoperative UBM. Anterior vitrectomy and goniosynechialysis were then performed as treatment. Conclusion Pupillary block glaucoma is a rare type of infantile aphakic glaucoma. Application of intraoperative UBM can assist in the differential diagnosis of aphakic glaucoma in infants.
