Purpose: We analyzed postoperative Frisby-Davis distance (FD2) stereotest scores and changes in the angle of deviation, and the correlation between postoperative FD2 stereotest scores and long-term surgical outcomes, in patients with intermittent exotropia. Methods: This retrospective study included patients aged less than 12 years with intermittent exotropia who underwent at least 28 months of postoperative follow-up. We analyzed the changes in the postoperative angle of deviation and preoperative and postoperative Titmus and FD2 stereotest scores. Surgical success rates at 28 months postoperatively were compared between the good (FD2 at 10 months postoperatively ≤ 10 arcsec) and bad (FD2 at 10 months postoperatively ≥ 15 arcsec) stereotest groups. Surgical success was defined as a horizontal deviation on distance measurement of 5 prism diopter (PD) esodeviation to 10 PD exodeviation at 1 year postoperatively. Results: This study included 101 patients. No significant difference was identified between preoperative and postoperative Titmus test scores. However, the FD2 stereotest scores were significantly improved at 10 months postoperatively (p = 0.001). A significant, positive correlation was observed between FD2 stereotest scores at 10 months postoperatively and the angles of deviation at distance at 10, 16, 22, and 28 months postoperatively (p ≤ 0.001 for all). The surgical success rates at 28 months postoperatively were 73.1% and 43.5% in the good and bad stereotest groups, respectively (p = 0.008). Conclusions Distance stereoacuity within 1 year postoperatively correlated with the postoperative angle of deviation at distance. Good distance stereoacuity (i.e., < 10 arcsec) within 1 year postoperatively correlated with a higher surgical success rate compared to bad distance stereoacuity.

Purpose: The results of the Hahn Chun Suk color test (Hahn test) and the Farnsworth-Munsell D-15 test (D-15 test) were compared in patients with acute optic neuritis. Methods: Patients with acute optic neuritis evaluated using both the Hahn and D-15 tests in the acute phase and 2 months later were evaluated. The results of the acute phase tests were compared. Correlations were sought between color deficiency and all of visual acuity, the visual field index (VFI), and the severity of optic disc edema. Changes in the test results 2 months later were also evaluated and correlated with other visual functions. Results: Twenty-seven eyes of 22 patients were enrolled. The mean patient age was 49.4 years and the logarithm of the minimum angle of resolution visual acuity 0.5. In the acute phase, the perception number was 10.06 in the Hahn test. On the D-15 test, the ‘strong’ grade predominated (40.7%). The concordance rates of severity and type were 55.6 and 54.5% between the two tests. In 9 of 12 eyes exhibiting inconsistent severity, the D-15 test afforded better results than did the Hahn test. A significant positive correlation was evident between the Hahn test results and visual acuity (r = 0.560, p = 0.002). The mean deviation (MD) and the VFI also correlated with the results of the Hahn test (r = -0.432, p = 0.027 for the MD; r = -0.517, p = 0.007 for the VFI). The D-15 test results correlated only with visual acuity (r = 0.476, p = 0.012). After 2 months, the results of both tests correlated significantly only with visual acuity. Conclusions In the acute phase, the concordances of the Hahn and D-15 test results were 55.6% in terms of severity and 54.5% in terms of type. The Hahn test results correlated with the visual acuity and VFI. In contrast, the D-15 test results correlated with visual acuity only.

Objective: The primary purpose of this literature review is to explore and integrate findings from various psychological autopsy (PA) studies to identify critical risk factors associated with adolescent suicide and evaluate the methodologies employed in these investigations. Methods: A systematic review of 15 studies reporting psychological autopsies of adolescent suicides was conducted. Data sources included databases such as PubMed, Google Scholar, and RISS. Studies were selected based on empirical research focused on adolescent suicides, conducted since 1970, and written in English. Two reviewers independently screened and selected studies, with a third reviewer resolving any disagreements. The studies were analyzed for sample characteristics, included variables, and specific features of the PA methodology. Results: The review identified consistent findings across studies, highlighting the significant role of mental illnesses and sociodemographic factors in adolescent suicides. Methodological variations were noted in interview timing, source selection, and the use of semi-structured interviews. The review also emphasized the importance of comprehensive data collection, including social network and mobile activity data, to better understand suicide risk factors. Key challenges identified include retrospective data bias and cultural differences affecting the generalizability of findings. Conclusion The review underscores the need for standardized PA procedures, particularly tailored to adolescents, to improve the reliability and validity of findings. The consistent association of psychiatric disorders with suicide risk emphasizes the urgent need for effective mental health interventions. Future research should focus on developing ethical, culturally sensitive, and methodologically rigorous approaches to enhance the understanding and prevention of adolescent suicide.

Purpose: We analyzed the characteristics of patients with refractive accommodative esotropia (RAET) who required glasses for stable alignment after a myopic shift. Methods: We retrospectively analyzed the medical records of patients diagnosed with RAET at the initial visit, and who had developed a myopic shift in both eyes over the 5-year follow-up period. To evaluate clinical factors associated with the persistence of esotropia after myopia, the enrolled patients were divided into two groups; patients with RAET who needed glasses for stable alignment after a myopic shift (unstable group) and patients with RAET whose esotropia resolved after a myopic shift (stable group). Results: A total of 55 patients met the inclusion criteria. The mean follow-up period was 13.8 ± 5.7 years (5-27 years). Spherical equivalent (SE) refractive errors at the initial visit were +3.1 ± 1.6 diopters (D) (+1.00 to +7.25 D) and -1.5 ± 0.9 D (-4.38 to -0.5 D) at the last visit. Of the 55 RAET patients, 24 were included in the unstable group and 31 were included in the stable group. No significant differences in gender, age at diagnosis, SE refractive error, or angle of esotropia with glasses were observed between the two groups. However, significantly more patients failed the Lang I test or had anisometropia over 1.5 D at the last visit, and the duration between the onset of esotropia and prescribing glasses was significantly longer in the unstable group than in the stable group. Conclusions Glasses may be needed for stable alignment even after a myopic shift in RAET patients with long durations of misalignment, poor stereopsis, and anisometropia.

Purpose: We report a case of idiopathic chiasmal optic neuritis in a pediatric patient.Case summary: A 13-year-old boy with no history of systemic disease was referred to our ophthalmology clinic because of visual disturbance in both eyes of 5 days in duration. The best-corrected visual acuity was 0.08 in the right eye and finger counting at 30 cm in the left eye; mild blurring of the disc margins (both eyes) was evident on fundus examination, as were temporal hemianopsia in the right eye and diffuse field loss in the left eye. Brain magnetic resonance imaging revealed focal nodular enhancement in the optic chiasm. Blood and cerebral fluid analysis yielded no evidence of infection or autoimmune disease. Therefore, we diagnosed isolated idiopathic chiasmal optic neuritis and commenced a systemic steroid. After 5 days, the visual acuity began to improve, and the field defect was almost eliminated (except for a small central scotoma) at 1 month. He has remained stable to the time of writing (4 months after treatment) and his visual acuity has normalized. Conclusions Isolated idiopathic chiasmal optic neuritis developed in a pediatric patient and the visual function improved after steroid treatment. Although there was no evidence of systemic demyelinating disease, regular observation is scheduled given the possibility of late-onset disease.
