Intravitreal triamcinolone and bevacizumab are emerging treatment modalities for the patients of macular oedema; however, they are known to raise intraocular pressure. A 61 year old diabetic male patient developed glaucoma after administration of triamcinolone acetonide and bevacizumab intravitreally for treatment of macular oedema. His intraocular pressure was raised up to about 42 mm Hg. Such high and sustained rise in intraocular pressure may lead to vision loss by damaging the optic nerve. The patient was managed by local as well as systematic therapy and was recovered after 1 month from the occurrence of an event. Intraocular pressure should be monitored in patients receiving intravitreal triamcinolone and bevacizumab. Risk benefit analysis must be done before using IVTA and IVB in patients with diabetic macular oedema.

Objectives This study aimed to identify the etiology and the direction of dislocation of the natural crystalline lens or intraocular lens (IOL) in IOL intrascleral fixation surgery and to determine the change in intraocular pressure (IOP) after surgery. Methods We retrospectively investigated the diagnosis, direction of lens and IOL dislocation, and IOP before and after surgery (preoperatively and one day, one week, and one month postoperatively) in 236 eyes from 228 patients who underwent IOL intrascleral fixation at Chiba University Hospital between February 2015 and September 2020. Results IOL intrascleral fixation was performed in 48 (20.

Primary open-angle glaucoma (POAG), known as a common ocular disease with genetic heterogeneity, is characterized by progressive optic disc atrophy and visual field defects. This study aimed to assess the contribution of previously reported POAG-associated genes and investigate potential functional variations and genotype-phenotype correlations in a Han Chinese population. DNA from 500 cases and 500 controls was pooled and sequenced using a customized panel of 398 candidate genes.

Purpose: Aqueous humor inflow rate, a key parameter influencing aqueous humor dynamics, is typically measured by fluorophotometry. Analyzing fluorophotometric data depends, inter alia, on the volume of aqueous humor in the anterior chamber but not the posterior chamber. Previous fluorophotometric studies of the aqueous inflow rate in mice have assumed the ratio of anterior:posterior volumes in mice to be similar to those in humans.

Purpose: Pressure resistance characteristics of the Paul glaucoma implant (PGI) and Ahmed ClearPath 250 (ACP), with and without the insertion of polypropylene thread in their tubes, were evaluated.
Methods: The in vitro flow pressure was evaluated at varying flow rates, both with and without threads (6-0 for PGI and 4-0 or 3-0 for ACP). Cross-sectional areas of the tube lumen and thread were measured to calculate pressure resistance using the Hagen-Poiseuille equation.

To evaluate the effectiveness of postoperative intravitreal bevacizumab (IVB) in preventing neovascular glaucoma (NVG) and identify associated risk factors in patients with proliferative diabetic retinopathy (PDR) undergoing phacovitrectomy. Patients with PDR who underwent phacovitrectomy were enrolled and categorized into two subgroups based on their postoperative treatment regimen: one group received IVB within 2 months following phacovitrectomy (Group 1); the other did not receive IVB during this period (Group 2). A comparative analysis evaluated the distinguishing characteristics of the two groups after 1:1 propensity score matching.
