Our study confirms some other studies in showing that in AD patients there is a reduction of parapapillary and macular RNFL thickness and macular volume as measured by OCT. The reduction in macular volume was related to the severity of cognitive impairment.
Objective: To evaluate the effects of menopause and hormone replacement therapy (HRT) on the quality and amount of tear, intraocular pressure (IOP) and retrobulbar blood flow velocities. Patients and Methods: Twenty women aged between 40 and 50 years, free of ocular and systemic diseases and planning to receive HRT were recruited as the study group. Twenty-four healthy, age-matched but still menstruating women were enrolled as controls. On the first day of study basal and reflex Schirmer test, tear break-up time and IOP measurements (at 08.00, 12.00 and 16.00 h) were performed for all groups. On the second day of the study, the peak systolic velocity (PSV), end diastolic velocity (EDV) and resistivity index (RI) of the ophthalmic (OA), central retinal (CRA), nasal (NSPCA) and temporal short posterior ciliary (TSPCA) arteries were determined by color Doppler imaging. The menopausal group received HRT for 2 months, when all measurements were repeated for the 15 women who had received HRT on a daily basis. Results: The quality and amount of tear decreased (p < 0.01), IOP (p < 0.01) and RI of the CRA, TPCA and NPCA (p < 0.05) increased in postmenopausal women compared with the control group. After 2 months of HRT, the quality and amount of tear had increased (p < 0.001) and the IOP had decreased (p < 0.001). The PSV of the CRA and TSPCA had decreased (p < 0.05), as had the RI in the CRA (p < 0.001), NSPCA and TSPCA (p < 0.05). Conclusion: We conclude that age-induced changes on quality and amount of tear, IOP and retrobulbar blood flow are intensified by the menopause and that it may be possible to decrease the menopausal effects on these parameters by HRT.
Elevated levels of homocysteine in pseudoexfoliation patients with and without glaucoma may partly explain the increased risk of vascular disease among patients with pseudoexfoliation. No significant difference was found in plasma NO markers among the POAG, PXS, PXG, and the control subjects.
Objective:
To compare the thickness of the retinal nerve fiber layer (RNFL), the macular volume, and the macular thickness of the amblyopic eye with those of the non-amblyopic eye in patients with unilateral strabismic amblyopia using optical coherence tomography (OCT).
Patients and Methods:
OCT was performed for 14 patients with unilateral strabismic amblyopia who had no neurologic disease. Nine male and 5 female patients, whose ages ranged from 5 to 18 years, were enrolled in the study. The RNFL thickness average analysis program was used to evaluate mean superior, inferior, temporal, and nasal thickness. The data for all clock quadrants (12 values averaged) were identified as the overall RNFL. The retinal thickness and volume analysis program was used to evaluate macular scans. Data were compared using the Mann–Whitney
U
test.
Results:
The mean age (± standard deviation) was 10.43 years (± 4.09 years). There were 6 right eyes and 8 left eyes with amblyopia; this group had a mean visual acuity (± standard error) of 0.3 (± 5.70). OCT parameters including the RNFL thickness in all quadrants, overall RNFL thickness, macular thickness, and macular volume showed no significant differences between the two groups (
P
> .05).
Conclusion:
Assessment of RNFL thickness, macular thickness, and macular volume with OCT revealed no difference between the two eyes of patients with unilateral strabismic amblyopia.

The results demonstrated that DTFC is more effective in reducing IOP than latanoprost and travoprost. Latanoprost and travoprost had similar ocular hypotensive effects in patients with PXG. All three drugs were well tolerated; there were fewer ocular side effects attributable in the latanoprost group. (Eur J Ophthalmol 2006; 15: 73-80).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
