Purpose: To determine the effect of viscogonioplasty and cataract extraction on intraocular pressure in patients with narrow angle glaucoma.
Methods: This was a double-masked randomized controlled trial involving 50 eyes (25 cases and 25 controls) from 38 consecutive patients. All patients underwent phacoemulsification with or without viscogonioplasty. The main outcome measures were intraocular pressure post-treatment and number of glaucoma medications post-treatment.
Results: Cases had a greater reduction in intraocular pressure than controls, with a mean intraocular pressure (standard deviation) at 12 months of 13.7 (±2.89) mmHg compared with 16.2 (±3.55) mmHg in controls (P = 0.009). Cases had a greater reduction in mean number of antiglaucoma medications than controls at 12-month review, with 13 of 25 eyes (52%) of cases controlled without any antiglaucoma therapy versus 9 of 25 (36%) of the controls (P = 0.005).
Conclusions: Viscogonioplasty combined with cataract extraction has a significantly greater effect than cataract extraction alone on lowering intraocular pressure in patients with poorly controlled narrow angle glaucoma and should therefore be considered as a treatment option for patients with this condition.

Introduction: This study aimed to compare changes in retinal oxygen saturation 1 month after femtosecond-assisted laser in situ keratomileusis (FS-LASIK) in Chinese adults with myopia using retinal oximetry.
Methods: In this prospective, observational, single-center cohort study, Chinese adults aged 18-45 years with myopia were categorized into four groups according to spherical equivalent (SE), with 66 eyes characterized as low myopia (LM -3.00D < SE ≤ -0.

This case study details a 41-year-old male patient with Freeman-Sheldon syndrome (FSS) who presented with ocular hypertension. The intraocular pressure (IOP) in his right eye progressively increased over time, leading to visual field loss, culminating in a diagnosis of juvenile-onset open-angle glaucoma (JOAG). Despite conventional medical therapies, adequate IOP control was not achieved, necessitating his referral to Nagoya City University Hospital.

Persistent hypotony following Tanito microhook trabeculotomy (TMH) is rare but may occur due to the development of cyclodialysis clefts. We report a case of a Japanese man in his 40s who developed persistent hypotony and hypotony maculopathy after TMH in the left eye. Fourteen months after the surgery, the patient was referred to our institution due to prolonged hypotony that remained undiagnosed and untreated despite evaluations with gonioscopy and anterior segment optical coherence tomography (AS-OCT) at the referring clinic.

Background: Central retinal vein occlusion and cilioretinal artery occlusion are rare but serious ocular conditions that can lead to significant visual impairment. While few cases of central retinal vein occlusion and cilioretinal artery occlusion have been individually reported, concurrent occlusion of both vessels is extremely rare, particularly in younger patients without traditional vascular risk factors. We present the first reported case of simultaneous central retinal vein occlusion and cilioretinal artery occlusion in a young female patient associated with short-term use of progestin-only oral contraceptives (OCPs).
