Background: To correlate the findings of optical coherence tomography (OCT) evaluation of retinal nerve fiber layer (RNFL) thickness with visual field changes in glaucomatous, ocular hypertensive and normal eyes.
Materials And Methods: Thirty consecutive normal, 30 consecutive ocular hypertensive and 30 consecutive glaucomatous eyes underwent a complete ophthalmic examination, including applanation tonometry, disc evaluation, (30-2) Humphrey field analyzer white on white (W/W) perimetry and short- wavelength automated perimetry. Thickness of the RNFL around the optic disc was determined with 3.4 mm diameter-wide OCT scans. Average and segmental RNFL thickness values were compared among all groups. A correlation was sought between global indices of perimetry and RNFL thickness.
Results: Of the 90 eyes enrolled (mean age of patients 52.32+/-10.11 years), the mean RNFL thickness was significantly less in ocular hypertensive (82.87+/-17.21 mm; P =0.008 and glaucomatous eyes (52.95+/-31.10 microm; P < 0.001), than in normals (94.26+/-12.36 microm). The RNFL was significantly thinner inferiorly in glaucomatous eyes (64.41+/-43.68 microm; P<0.001). than in normals (120.15+/-14.32 microm) and ocular hypertensives (107.87+/-25.79 microm; P<0.001). Ocular hypertensives had thinner RNFL in the nasal, inferior and temporal quadrants (P<0.001) when compared to normals. Global indices in ocular hypertensives on SWAP showed Mean Deviation (MD) of 5.32+/-4.49, Pattern Standard Deviation (PSD) 3.83+/-1.59 and Corrected Pattern Standard Deviation (CPSD) 2.84+/-1.85. The RNFL thickness could not be significantly correlated with global indices of visual fields in ocular hypertensives.
Conclusion: Optical coherence tomography is capable of detecting changes at the level of RNFL in ocular hypertensive eyes with normal appearance of discs and W/W perimetry fields.

Background: Optic atrophy (OA) is primarily caused by damage to the retinal pathway system, including widespread degeneration of retinal ganglion cells and axons, leading to visual impairment and blindness. Despite its clinical significance and diverse etiological factors, there is currently a lack of comprehensive bibliometric analyses exploring research trends and hotspots within this field.
Method: This study retrieved relevant literature on OA published between 2003 and 2023 from the Web of Science Core Collection database.

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.

This review addresses the correlation between arterial stiffness, measured by pulse wave velocity (PWV), and retinal microvascular changes, highlighting the retina as an important accessible window for inferences about cardiovascular health. Arterial stiffness, intrinsically linked to vascular aging and several comorbidities, results in damage to the microcirculation, including ocular vasculature, which can act as a predictor of cardiovascular and cerebrovascular outcomes. The review highlights the relationship between PWV assessment and funduscopic examination, with the aim of improving diagnostic accuracy and optimizing the clinical application of these tools in the management of cardiovascular and ophthalmological diseases, thus promoting more effective and early intervention.

The abrupt and substantial elevation of intraocular pressure (IOP) in acute glaucoma induces retinal ischemia/reperfusion (I/R) injury, resulting in progressive retinal ganglion cell (RGC) death and irreversible visual impairment. PANoptosis, a form of regulated cell death consisting of pyroptosis, apoptosis and necroptosis, is reported to be involved in high IOP-induced RGC death. However, the precise mechanisms of RGC death remain unclear, and neuroinflammation is considered to play a vital role.

Purpose: This study evaluated the efficacy, safety, and tolerability of a single-dose, preservative-free (PF) Dorzolamide/Timolol combination (Twinzol-SDU).
Methods: A 3-month single-arm, multicenter, prospective cohort study was conducted in Egypt between January 2021 and October 2022 on previously diagnosed and controlled patients with ocular hypertension and/or glaucoma. Efficacy was assessed using the change in intraocular pressure (IOP) after 6 and 12 weeks.
