“…Nonetheless, the DS most frequently used prism lenses in daily life activity in order to relieve the diplopia compared to NDS (57.1% vs. 20.8%, p = 0.016). Prism lenses are effective in correcting the residual strabismus after strabismus surgery, but their use is associated with side effects, such as headaches, dizziness, eye strain, and pulling [ 18 , 19 ].…”

Backgrounds To report the long-term surgical outcomes and the impact on daily life activities of strabismus surgery in patients with Thyroid Associated Orbitopathy (TAO) with and without previous orbital decompression. Methods Patients who underwent strabismus surgery for TAO were retrospectively reviewed. The primary outcome was to evaluate the influence of orbital decompression on the outcomes of TAO related strabismus surgery. Surgical success was defined by the resolution of diplopia and a post-operative deviation < 10 prism diopters (PD). The secondary outcomes were the clinical features, surgical approaches, and impact on daily life activities. Results A total of 45 patients were included in the study. The decompression surgery group (DS) included 21 patients (46.7%), whereas the non-decompression surgery group (NDS) patients were 24 (53.3%). The mean follow-up time from the last strabismus surgery was 2,8 years (range 8–200 months). Successful surgical outcome was achieved in 57,1% of patients in the DS, and 75% of patients in the NDS (p = 0,226). DS patients required almost twice the number of surgical interventions for strabismus compared to the NDS (1,95 vs. 1,16 respectively, p = 0,006), a higher number of extraocular muscles recessed in the first surgery (2,67 vs. 1,08 respectively, p < 0.001), and a lower rate of unidirectional surgery compared to NDS (23% vs. 95%, p < 0,001). At the pre-operative assessment, 71.4% of DS patients had eso-hypotropia, while no patients had this type of strabismus in the NDS group (p < 0.001). On the other hand, the hypotropia rate was 79.2% in NDS patients and only 4.8% in DS patients (p < 0.001). Moreover, 21,8% of NDS patients used prism lenses in daily life activities, compared to 42.9% of patients that used prism lenses to reduce the impairment in their daily life activities (p = 0.016). Conclusions The results of our study showed that DS patients required almost twice the number of strabismus surgical procedures, a higher number of extraocular muscles recessed in the first surgery, and an increased need for prism lenses to correct the residual deviation compared to the NDS, but with similar long-term surgical outcomes.

“…Generally, diplopia treatment using prism glasses is less effective when the prism is large and in incomitant strabismus due to uncomfortable symptoms. However, prism glasses are highly effective for esotropic strabismus [ 9 – 12 ]. Therefore, it is hypothesized that the treatment effect of prism glasses is suitable for patients with sagging eye syndrome because the angle of deviation is relatively small, and the type of strabismus is mainly esotropia.…”

Purpose:To retrospectively analyze the relative frequency and describe the clinical features of sagging eye syndrome in Korean patients from a single center. Methods:We retrospectively analyzed the medical records of patients with diplopia, aged over 40 years, who visited our hospital from January 2018 to December 2020. The relative frequency of sagging eye syndrome was examined by classifying the cause of diplopia. Clinical features, such as age, sex, strabismus type, angle of deviation, treatment method, and prognosis, were evaluated.Results: A total of 128 patients were identified, of which 23 (18%) were diagnosed with sagging eye syndrome, including 12 males (52.2%) and 11 females (47.9%). Their mean age was 74.6 ± 7.6 (61~89) years, and all patients were >60 years. Among the 62 patients with diplopia and age over 60 years, the relative frequency of sagging eye syndrome was 23 (37.1%), the highest among all age groups. Among the 23 patients with sagging eye syndrome, 9 (39.1%) patients had only distance esotropia, with a mean distance esotropia value of 10.1 ± 8.6 (4~25) prism diopters (PD) at the first visit; 9 (39.1%) patients had a combination of esotropia and vertical strabismus, with a mean esotropia value of 6.2 ± 4.8 (2~12) PD and a vertical angle of 4.7± 3.2 (2~10) PD; and 5 (21.7%) patients had only vertical strabismus, with an average vertical strabismus angle of 3.3 ± 1.6 (4~8) PD. Furthermore, 17/23 (73.9%) patients used prism glasses, in whom the symptoms of diplopia disappeared. Finally, only 3 (13.0%) patients underwent surgery. Conclusion:Sagging eye syndrome in Korean patients was identified in those >60 years with a similar male-to-female ratio. Moreover, nonsurgical treatments, such as prism glasses, largely helped relieve the symptoms of sagging eye syndrome.
