Purpose: To investigate the epidemiology of strabismus in cases of pediatric cataracts. To assess visual outcome following orthoptic treatment for amblyopia in cases of cataracts in the pediatric age group. Methods: This was a retrospective cohort study. We investigated a consecutive series of pediatric patients with congenital, developing, or traumatic cataracts who underwent surgery between January 1999 and April 2012 at our center. Patient demographics, cataract type, presenting symptoms, surgical intervention, postoperative visual acuity, and follow-up refractive changes were recorded. Results: In total, 1331 eyes of 1043 children were included: unilateral cataracts were present in 785 (59%) eyes. There were 605 (45.5%) traumatic and 726 (54.5%) non-traumatic cases. Ages at surgery ranged from 1 to 215 months. All eyes were examined for ocular alignment; 66 (5%) were found to manifest strabismus. Deviation was significantly associated with age at intervention (p < 0.001), sensory nystagmus (p < 0.001), and etiology of cataracts (p < 0.001). We found significant differences in visual outcome following amblyopia therapy (p < 0.001). Conclusions: Surgical treatment with intraocular lens implantation in children with congenital, developmental, or traumatic cataracts is effective for visual rehabilitation. Orthoptic treatment made a significant difference in visual outcome (p < 0.001).
Aim: This study investigated visual outcomes and factors that impact vision in children receiving secondary Intraocular Lens (IOL) implants. Methods: Children who had traumatic or congenital cataracts and underwent secondary lens implantation for aphakia at Drashti Netralaya between 2000 and 2019 were retrospectively examined. We included all the eyes with secondary implants for aphakia correction with placement either in the bag or sulcus or through scleral fixation. We obtained data from electronic medical records and analyzed using SPSS 22 through descriptive analysis, cross tabulation and t test. We evaluated visual outcomes among different patients. Results: Our cohort consisted of 84 eyes (mean age: 7.88 ± 6.07 years). Of the 84 eyes, 24 (28.6%) and 60 (71.4%) were female and male patients, respectively and 32 (38.1%) had traumatic cataract. We observed significant improvements in vision following lens implantation (p=0.000). Those with nontraumatic cataracts exhibited better outcomes that did the traumatic cataract group (p=0.004). Corneal opacity caused comorbidities in the traumatic group (14/52, 14.29%). Visual outcomes significantly improved in young patients and were not affected by other variables. Conclusion: Secondary lens implantation significantly improved vision in aphakic children. Young patients and those with nontraumatic cataracts demonstrated more favorable visual outcomes.
Purpose: To describe the incidence, aetiologies and follow-up of patients with paralytic strabismus.Methods: This retrospective study included 193 strabismic patients with isolated III, IV or VI cranial nerve palsy, cases of the strabismus from the Department of Ophthalmology of the tertiary care center in western-central India between January 2007 and December 2020. The present study analyzed the injured cranial nerve, the affected eye, sex distribution, etiology and follow-up.Results: About 5.7% of the cases were congenital and 16.1% were of pediatric age. The Trochlear nerve was the most frequently affected (56.5%) in these cases. Incidence was higher in males (58.1%) than females. Trauma was the common cause of III (7.1%), IV (8.3%) and VI (50%) nerve palsy. The disease management modalities included surgical, medical and spontaneous resolution.Conclusions: The sixth cranial nerve was affected most frequently. However, the most common underlying cause was yet undetermined.
