Prematurity May Affect the Postoperative Sensory Results in Children With Strabismus.

PURPOSE: To analyze the motor and sensory outcomes of strabismus surgery in children born preterm (premature group) and full-term (control group). METHODS: The study was performed at a tertiary university hospital. Children who underwent strabismus surgery between 2012 and 2019 were retrospectively reviewed. The success of surgery, postoperative over-correction and undercorrection rates, and stereopsis and fusion test results were compared between the premature and control groups. RESULTS: There were 70 patients in the premature group (mean gestational age: 31.25 weeks; range: 24 to 35 weeks) and 242 patients in the control group. The amounts of preoperative and postoperative deviations and overcorrection, undercorrection, and success rates were similar between the premature and control groups (P > .05). Stereopsis improved from 560 to 300 arc/sec postoperatively in the premature group (P = .066) and from 1,156 to 685 arc/sec in the control group (P < .001). The rate of fusion increased from 12.5% to 25% in the premature group (P = .50) and from 17% to 47% in the control group (P < .001). The analysis of strabismus subgroups revealed significant improvement of fusion in full-term patients (P < .001) and not in preterm patients (P = .50) with esotropia. Preoperative amount of deviation was the only risk factor for surgical success (P < .001). Age, sex, history of prematurity, and spherical equivalent refraction were not correlated with undercorrection (P > .05). CONCLUSIONS: Regardless of the type of strabismus, although the functional results after strabismus surgery were similar in preterm and full-term patients, the gain of stereopsis and central fusion was significantly higher in full-term patients compared to preterm patients.

Surgical management of intraocular lens dislocations / Tratamento cirúrgico dos deslocamentos de lentes intraoculares

ABSTRACTPurpose:To report and compare the surgical, visual, and anatomical outcomes following treatment of dislocated intraocular lenses (IOLs).Methods:The medical records of 28 eyes of 28 patients were evaluated. Age, gender, pre-and postoperative best-corrected visual acuity (BCVA), surgical methods, and complications were recorded.Results:Pre-and postoperative BCVA ranged from counting fingers to 20/32 and from counting fingers to 20/25, respectively. Late-onset dislocations were the most frequently observed complication. The most frequent surgical method was IOL repositioning in 15 of 28 patients, followed by IOL exchange in 11 patients, and IOL removal in 2 patients. Only 1 patient required surgical re-intervention with IOL capture.Conclusions:Visual acuity improved following the use of either IOL repositioning or IOL exchange. No superiority of one method over the other was observed. In the present retrospective case series, management of dislocated IOLs with repositioning or exchange of the primary implant conferred comparable surgical and visual outcomes.

RESUMOObjetivo:Relatar e comparar as abordagens cirúrgicas e os resultados visuais e anatômicos no tratamento de lentes intraoculares (IOL) deslocadas.Métodos:Foram avaliados os registros médicos de 28 olhos de 28 pacientes. Idade, sexo, melhor acuidade visual corrigida pré e pós-operatória, abordagens cirúrgicas e complicações foram registrados.Resultados:Melhor acuidade visual corrigida pré e pós-operatória variou de conta dedos a 20/32 e de conta dedos a 20/25, respectivamente. Os deslocamentos tardios foram os mais frequentemente encontrados. A cirurgia mais frequente foi o reposicionamento da IOL em 15 dos 28 pacientes, em seguida, o troca da IOL em 11 pacientes, e a remoção da IOL em dois pacientes. Apenas um caso de necessitou de reintervenção devido à captura da IOL.Conclusões:A acuidade visual melhorou em ambas as abordagens, reposicionamento e troca de IOL. Não houve superioridade de um método sobre o outro. Na presente série de casos retrospectiva, o tratamento do deslocamento de IOL com reposição ou troca do implante primário gerou resultados cirúrgicos e visuais comparáveis.
