Glaucoma is a group of eye diseases characterized by progressive harm to the optic nerve that often results in loss of vision and blindness. Recent studies suggest that deregulation in the expression of a particular type of RNAs named long noncoding RNAs (lncRNAs) can impact the development of glaucoma and, hence, are promising targets for drug discovery. LncRNAs are transcripts with a length longer than 200 nucleotides that are not translated into proteins.

Background: Trabeculectomy (TRAB) traditionally has been the gold-standard surgical treatment for primary open-angle glaucoma (POAG), while gonioscopy-assisted transluminal trabeculotomy (GATT) is an emerging minimally invasive surgery used for the treatment of various open-angle glaucoma (OAG) types. In this study, we aimed to compare the efficacy and safety between GATT and TRAB for the treatment of POAG.

Methods: This cohort study included eyes with POAG that underwent a single GATT (30 eyes) or TRAB (34 eyes).

Background: The greater San Francisco metropolitan bay area is home to 270,000 Filipino immigrants and the second largest Filipino-American population in the United States. Despite this, Filipino-Americans are aggregated with the general "Asian-American" category, making it a challenge to obtain accurate population health data on social determinants of health. One area that is concerning is the lack of research on Filipino-American eye health experiences.

Article Synopsis
  • North India experiences an annual outbreak of viral conjunctivitis during the monsoon season, impacting a large number of people, most of whom recover without treatment.
  • Patients with a history of trabeculectomy (eye surgery for glaucoma) are at increased risk as conjunctivitis can lead to serious complications like blebitis and bacterial/fungal infections.
  • It's crucial to educate these patients about the conjunctivitis outbreak and the warning signs that require immediate medical attention to prevent complications.

Intraocular pressure (IOP) elevation is the primary risk factor and currently the main treatable factor for progression of glaucomatous optic neuropathy. In addition to direct clinical and living animal in vivo studies, ex vivo perfusion of anterior segments and whole eyes is a key technique for studying conventional outflow function as it is responsible for IOP regulation. We present well-tested experimental details, protocols, considerations, advantages, and limitations of several ex vivo model systems for studying IOP regulation.

Glaucoma is a heterogenous group of optic neuropathies characterized by the degeneration of optic nerve axons and the progressive loss of retinal ganglion cells (RGCs), which could ultimately lead to vision loss. Elevated intraocular pressure (IOP) is a major risk factor in the development of glaucoma, and reducing IOP remains the main therapeutic strategy. Endothelin-1 (ET-1), a potent vasoactive peptide, has been shown to produce neurodegenerative effects in animal models of glaucoma.

Primary open-angle glaucoma (POAG) is the most common form of glaucoma. This condition leads to optic nerve degeneration and eventually to blindness. Tobacco smoking, alcohol consumption, fast-food diets, obesity, heavy weight lifting, high-intensity physical exercises, and many other bad habits are lifestyle-related risk factors for POAG.

Long-term use of topical prostaglandins might initiate chronic conjunctival inflammation, leading to poor outcomes of glaucoma surgery. The aim of this study was to evaluate the immunoexpression pattern of HSP70, CTGF, SNAIL, aSMA, cMYB, and HIFa in the conjunctiva, episclera, and deep sclera in patients with glaucoma undergoing deep sclerectomy in order to establish an association between staining intensities and prostaglandin F2 (PGF2) treatment. Double immunofluorescence (HSP70, CTGF, SNAIL, aSMA, cMYB, and HIFa) was performed on conjunctiva, episclera, and deep sclera samples, which were obtained from 23 patients treated with PGF2 and 8 patients without PGF2 treatment.

Introduction Fixed-dose combinations (FDCs) have the potential in glaucoma management to improve efficacy due to the complementary mechanism of action of the drugs as well as compliance while reducing adverse effects by minimizing exposure to preservatives and the financial burden on the patients. FDC of brinzolamide/timolol has demonstrated efficacy and safety in multinational phase 3 studies in primary open-angle glaucoma (POAG) and ocular hypertension. However, efficacy and safety in the Indian population are not known.

Axial elongation in nonpathologic high myopia: Ocular structural changes and glaucoma diagnostic challenges.

Asia Pac J Ophthalmol (Phila)

December 2024

State Key Laboratory of Ophthalmology, Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangdong Provincial Key Laboratory of Ophthalmology and Visual Science, Guangdong Provincial Clinical Research Center for Ocular Diseases, Guangzhou, China. Electronic address:

Axial elongation continues in highly myopic adult eyes, even in the absence of pathologic changes such as posterior staphyloma or chorioretinal atrophy. This ongoing axial elongation leads to structural changes in the macular and peripapillary regions, including chorioretinal thinning, reduced vascular perfusion and optic disc tilting and rotation, among others. These alterations can affect the acquisition and interpretation of optical coherence tomography, optical coherence tomography angiography and fundus photographs, potentially introducing artifacts and diminishing the accuracy of glaucoma diagnosis in highly myopic eyes.

Purpose: Disorders of the anterior optic nerve cause quantifiable patterns, or archetypes (AT), in visual fields (VFs) obtained using standardized automated perimetry using stimulus size III (size III). VFs with stimulus size V (size V) can reduce retest variability in eyes with moderate to severe loss. We postulated that VF testing using both stimuli would show similar ATs in eyes with glaucoma and nonarteritic anterior ischemic optic neuropathy (NAION).

The anatomy and vasculature of the optic nerve head are complex and subject to numerous variations. The main risk factor for glaucomatous optic neuropathy is elevated intraocular pressure, but many other factors have been identified. A vascular component seems to play an important role in the pathogenesis and/or progression of glaucomatous optic neuropathy, either under the influence of ocular hypertension or as an independent risk factor, particularly as in normal tension glaucoma (NTG).
