Purpose: To survey the use of triamcinolone acetonide (TA) for ocular disease in Japan.
Subjects And Methods: A questionnaire was sent to 1,236 teaching hospitals approved by the Japanese Ophthalmological Society requesting information regarding indications, methods, efficacy and complications of TA administered from January through December 2005. The survey specifically covered the use of TA in intravitreal injections, sub-Tenon's injections and intraoperatively during vitrectomy procedures.
Results: Four-hundred and fifty-nine hospitals responded to the survey (response rate 36.9%) involving TA use in 44,827 eyes. Intravitreal injections of TA were administered to 5,665 eyes in 159 hospitals. The average dose was 6.53 mg for a single injection and was reported to have highest efficacy in eyes with diabetic macular edema, followed by retinal vein occlusion. Complications included cataract formation in 116 eyes (2.04%), glaucoma requiring filtration surgery in 32 eyes (0.56%), endophthalmitis in 7 eyes (0.12%), and blepharoptosis in 8 eyes (0.14%). Sub-Tenon's injections of TA were administered to 12,343 eyes in 308 hospitals. The average dose was 19.87 mg for a single injection and had the highest efficacy in eyes with diabetic macular edema, followed by retinal vein occlusion. Sub-Tenon's administration of TA was also frequently used for uveitis. Complications reported were cataract formation in 191 eyes (1.55%), glaucoma requiring filtration surgery in 33 eyes (0.26%), endophthalmitis in 1 eye (0.008%), periocular infection in 5 eyes (0.04%) and blepharoptosis in 43 eyes (0.35%). TA was used as an adjunct to vitrectomy in 26,819 eyes in 270 hospitals and was judged to be most useful in the separation of posterior hyaloid from the retina. Complications included cataract formation in 49 eyes (0.18%), glaucoma requiring filtration surgery in 32 eyes (0.56%), and endophthalmitis in 7 eyes (0.026%).
Conclusions: TA is being widely administered for ocular diseases in Japan, and appears to have good efficacy in a variety of indications. Several complications related to TA use were reported, however the rates of complications were low.

Elevated intraocular pressure (IOP) is a significant risk factor for glaucoma, causing structural and functional damage to the eye. Increased IOP compromises the metabolic and structural integrity of retinal ganglion cell (RGC) axons, leading to progressive degeneration and influencing the ocular immune response. This study investigated early cellular and molecular changes in the retina and optic nerve (ON) following ocular hypertension (OHT).

Background: Perception-related errors comprise most diagnostic mistakes in radiology. To mitigate this problem, radiologists use personalized and high-dimensional visual search strategies, otherwise known as search patterns. Qualitative descriptions of these search patterns, which involve the physician verbalizing or annotating the order he or she analyzes the image, can be unreliable due to discrepancies in what is reported versus the actual visual patterns.

Herein, we describe the surgical approach and evaluate the visual outcomes of patients following scleral fixation of the LAL.
Methods: Retrospective, single-surgeon surgical case series of 3 patients (3 eyes) with intraocular lens complications, who underwent combined pars plana vitrectomy and sutureless needle assisted intrascleral haptic fixation of the LAL between April 2022, to August 2023.

Purpose: To identify optical coherence tomography (OCT)-based imaging biomarkers that can localize focal leakage points without fluorescein angiography in central serous chorioretinopathy (CSC).
Methods: This retrospective case-control study analyzed 119 consecutive patients (123 eyes) with CSC between April 2018 and February 2024, comprising 66 eyes with focal-leakage type and 57 eyes with diffuse-leakage type. We assessed leakage sites using OCT, and the proportions of OCT findings were compared between focal- and diffuse-leakage types.

Purpose: To assess if drusen volume can serve as structural clinical outcome marker in Malattia Leventinese (ML), and to evaluate whether cones or rods are more affected by its progression, using multimodal imaging and mesopic and two-color scotopic microperimetry.
Methods: This was a prospective monocentric cross-sectional cohort study of participants with genetically confirmed ML. Participants were classified according to morphology.
