Purpose:
This study compared the long-term outcomes and complications associated with sutured and suture-less scleral fixed intraocular lenses (SFIOLs), the two primary surgical techniques for scleral fixation of IOLs.
Methods:
A total of 90 patients were included in the study with 46 in the sutured group and 44 in the suture-less group. These patients underwent SFIOL between January 2019 and June 2023 due to IOL dislocation, aphakia, or crystalline lens dislocation. Collected data included age, gender, axial length, operative time, best corrected visual acuity (BCVA), intraocular pressure (IOP), refractive value, refractive error, ocular residual astigmatism, IOL dislocation, recurrent IOL dislocation, IOL tilt, and IOL iris capture. Changes from preoperative status to 1 year postoperatively were assessed.
Results:
No significant differences were found between the sutured and suture-less groups regarding preoperative BCVA, IOP, and refractive values. However, the suture-less group demonstrated significantly better BCVA at both 1 week and 1 month postoperatively compared to the sutured group (p = 0.010, 0.015, respectively). The refractive error in the suture-less group was also significantly lower at 1 week postoperatively (p = 0.020). Ocular residual astigmatism was consistently lower in the suture-less group across all postoperative intervals (p < 0.001). While the suture-less group showed a shorter average surgical time, there was greater variability in operative duration (p < 0.001, 0.024, respectively). Additionally, a longer axial length was associated with an increased incidence of IOL iris capture (p = 0.004).
Conclusions
Suture-less SFIOL is associated with shorter operative times, although with greater variability. Patients in the suture-less group experienced faster BCVA improvement, reduced refractive error, and lower ocular residual astigmatism compared to those in the sutured group.

Purpose:
This study aimed to determine the changes in choroidal thickness induced by pioglitazone in diabetic patients.
Methods:
A total of 261 patients diagnosed with type 2 diabetes who had taken oral pioglitazone for more than 6 months were included in the study. After excluding patients who did not undergo regular eye examinations or who had ophthalmic surgery/interventions during the treatment period, a total of 40 eyes were included. The study examined the duration and dosage of pioglitazone, patient age, ocular axial length, refraction, glycated hemoglobin, systolic blood pressure, corrected visual acuity, macular thickness, choroidal thickness, and choroidal vascular index. Patients were categorized into a high-dose group if their pioglitazone dose was 30 mg or more per day, and a low-dose group if it was 15 mg or less. Choroidal thickness was measured below the subfovea and a 500 µm radius nasal and temporal to that location.
Results:
Choroidal thickness significantly increased after 6 and 12 months of pioglitazone (6.70 and 13.65 µm, respectively) in all subjects. When stratified by pioglitazone dosage, choroidal thickness increased at 6 and 12 months in both high-dose group (4.48 and 0.84 µm, respectively) and low-dose groups (6.85 and 21.45 µm, respectively), with a greater change observed in the low-dose group (p < 0.05). Based on the location of choroidal thickness measurements, a significant increase in choroidal thickness was observed at 6 and 12 months of pioglitazone treatment in the subfoveal (7.00 and 13.15 µm, respectively) and nasal regions (6.43 and 19.24 µm, respectively), while a significant increase was only observed after 6 months of treatment in the temporal region (8.53 µm, p < 0.05). The largest increase in choroidal thickness was observed in the nasal side.
Conclusions
This study found that choroidal thickness increased in diabetic patients after taking pioglitazone. Regular eye examinations are recommended for diabetic patients who are on pioglitazone.

Background:
This study aimed to observe the extent of retinal vascularization in patients with retinopathy of prematurity (ROP) who underwent deferred laser treatment (LT) after a single intravitreal bevacizumab injection (IVB).
Methods:
This study retrospectively evaluated 40 consecutive eyes in 21 infants who received a single IVB or LT. Deferred LT was performed in cases of ROP recurrence after a single IVB. To assess the amount of retinal vascularization between the initial IVB and deferred LT, the cases were divided into three groups based on treatment: single IVB, deferred LT after a single IVB, and prompt LT. The growth and associated complications were compared between groups.
Results:
There were 12, 16, and 12 eyes in the single IVB, deferred LT, and prompt LT groups, respectively. Deferred LT was performed at an average of 7.9 weeks after a single IVB. In the single IVB group, retinal vascularization proceeded to zone III, whereas the prompt LT group did not show any growth of vascularization beyond the laser scars. In the deferred LT group, during the window period before LT, retinal vascularization progressed from zone I to zone II posterior and from zone II posterior to zone II anterior, respectively, without further ROP recurrence.
Conclusions
Retinal vascularization progressed during the deferred window period, thereby reducing the area of the retina ablated by LT. A single IVB followed by deferred LT can be an alternative treatment option to prevent ablation of zone I or multiple IVBs.

Serotonin syndrome is an unexpected adverse reaction of serotonergic medication. Some drugs used by anesthesiologists may cause serotonin syndrome. Serotonin syndrome is known to be related to 5-hydroxytryptamine 1A and 5-hydroxytryptamine 2A agonism. However, recent research has revealed evidence that 5-hydroxytryptamine 3 (5-HT3) antagonism can also play a role in serotonin syndrome. Among the 5-HT3 antagonists, palonosetron is the most highly specific. In this study, we present the first case of fentanyl- and meperidine-induced serotonin syndrome precipitated by palonosetron in general anesthesia.

Trigeminal neuralgia is a severe pain disorder characterized by recurrent paroxysms of unilateral facial pain that is typically lancinating or stabbing, and is activated by cutaneous stimulation. Trigeminal alcohol neurolysis is an accepted treatment for trigeminal neuralgia. However, injections of alcohol must be placed accurately because alcohol is highly toxic. In this study, infraorbital alcohol neurolysises were performed under an ultrasound guidance. Ultrasound imaging is a safe, simple and non-invasive modality. This imaging tool allows fine adjustment of the needle tip and direct observation of the injectate. Two patients suffering from trigeminal neuralgia were treated with ultrasound-guided trigeminal alcohol neurolysis. They showed favorable pain relief without any serious complications over the 5- and 7-month follow-up, respectively.

The I-gel(TM) is a single-use supraglottic airway device introduced in 2007 which features a non-inflatable cuff and allows passage of a tracheal tube owing to its large diameter and short length of the airway tube. In this case, the authors experienced a difficult airway management on a 4-year-old boy with underlying Goldenhar syndrome who underwent a tonsillectomy. Intubation using a laryngoscope was unsuccessful at the first attempt. In the following attempt, we used the I-gel(TM) supraglottic airway for ventilation and were able to achieve successful intubation with a cuffed tube by using fiberoptic bronchoscope through the I-gel(TM) supraglottic airway. The authors suggest that I-gel(TM) is a useful device for ventilation and it has many advantages for tracheal intubation in pediatric patients with difficult airway.
