The high BW and GA of infants with severe ROP indicate wider screening criteria should be used in our country. BW might be a more important criterion than GA for ROP screening.
IVB appears to be useful for advanced ROP when laser treatment is precluded or not sufficient for preventing the progression of ROP. This pilot study indicates that IVB seems to contribute no further complications to the complications already present due to prematurity.
We found no significant differences in morphological and functional measures among amblyopic groups. However, we detected significant differences in the retinal function and morphology of both amblyopic and nonamblyopic eyes compared with healthy control eyes.
In our study, the only significant difference between persistent and resolved amblyopia groups was the initial VA. Neither OCT nor electrophysiological examinations were found to be useful in order to explain why some cases were resistant to the treatment for amblyopia.
To assess the efficacy of botulinum toxin A injection in the treatment of strabismus in patients with neurological impairment and evaluate the factors associated with treatment success. Methods: The study included 50 patients with strabismus and neurological impairment. In all children, botulinum toxin injection was performed into the appropriate extraocular muscle. The relationship between demographic features, clinical characteristics, and treatment success were analyzed. Results: In the study group, 34 patients had esotropia, and 16 patients had exotropia. As neurological problems, 36 patients had cerebral palsy, and 14 had hydrocephalus. The average follow-up period was 15.3 ± 7.3 months. The mean number of injections was 1.4 ± 0.6. The mean angle of deviation was 42.5 ± 13.2 PD before the treatment, which decreased to 12.8 ± 11.9 PD after the treatment. Successful motor alignment (orthotropia within 10 PD) was achieved in 60% of the patients. Binary logistic regression analysis revealed that esotropic misalignment and shorter duration of strabismus was significantly associated with treatment success in the study group. Patients with esotropia and lower angles of misalignment were more likely to be treated with a single injection. Conclusion: The use of botulinum toxin A for the treatment of strabismus in children with neurological impairment is a good alternative to conventional surgical therapy with a lower risk of overcorrection. The treatment outcome is better in esodeviations and shorter duration of strabismus, implying an advantage of early treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
