RESUMEN
PURPOSE: To evaluate three months follow-up of SING IMT implant in patients affected by late-stage AMD. DESIGN: Prospective cohort study. SUBJECTS: In a total of 80 eyes of 40 patients who underwent the enrollment tests, 11 patients' eyes affected by late-stage AMD matched the inclusion criteria and underwent SING IMT implant from February to June 2022. METHODS: Before surgery, each patient underwent the enrollment examination to verify inclusion and exclusion criteria. MAIN OUTCOME MEASURES: BCVA for distance and for near, IOP, ACD and ECD were evaluated at 1 and 3 months follow up. Also quality of life in doing the activities of daily life was evaluated. RESULTS: BCVA for distance and for near improved from baseline to 3 months follow up (23.91 ± 9.418 ETDRS letters and 59.09 ± 11.58 ETDRS letters respectively (p < 0.001). An endothelial cell loss was shown (p < 0.001), with a rate of cell density reduction around 8.3% (baseline vs 3 months). CONCLUSIONS: SING IMT could be a valid surgical device to improve patients' sight and quality of life which have been deteriorated by late-stage macular degeneration. Further studies with more patients and longer follow up are needed to confirm our results.
RESUMEN
PURPOSE: To evaluate the change in sensory status and quality-of-life measures in adults with long-standing childhood-onset constant strabismus. METHODS: Consecutive patients with childhood-onset, long-term constant strabismus were enrolled. Sensory status was examined with Bagolini striated glasses test and Worth 4-dot test. Stereopsis was tested with the Lang and TNO stereopsis tests. Quality of life was studied with 2 different questionnaires (Short Form Health Survey [SF-36] and the Amblyopia and Strabismus Questionnaire [A&SQ]), which patients completed before and 3 months after strabismus surgery. RESULTS: A total of 20 patients (age range, 18-63 years) were included, 10 of whom were esotropic and 10 of whom were exotropic. Of these, 13 obtained a satisfactory postoperative alignment and demonstrated an increase of sensory status with Bagolini striated glasses. Six patients who demonstrated suppression preoperatively achieved fusion and stereopsis postoperatively. The mean score in all domains of the A&SQ improved significantly, particularly with regard to social contact and cosmesis (P = 0.00067), distance estimation (P = 0.000312), and visual disorientation (P = 0.004777). Similarly, the mean score in 7 of 8 areas in the SF-36 improved significantly, particularly with regard to physical function (P = 0.000564), general health (P = 0.002296), vitality (P = 0.002891), social function (P = 0.004234), and mental health (P = 0.000334). The overall mean score of both questionnaires improved in all patients with a satisfactory postoperative alignment and increase of sensory status. CONCLUSIONS: Surgical treatment of strabismus in adults with long-standing childhood-onset constant strabismus can result in patients feeling that their quality of life has improved and can restore binocular sensory function.
