In this largest reported series of FHC patients, we detected a strong association between FHC and intraocular antibody synthesis against rubella virus. Furthermore, in 11 patients, it was possible to confirm an additional intraocular antibody synthesis, in particular HSV. PCR-positive results in the aqueous humor were exclusively obtained for RV. In contrast to other studies, the RV genome could only be identified in two patients (10%).
BackgroundTo study biometric and structural ocular manifestations of Marfan syndrome (MFS).MethodsObservational, retrospective, comparative cohort study in a tertiary referral center on 285 MFS patients and 267 controls. Structural and biometric ocular characteristic were compared.ResultsMFS eyes were longer (axial length 24.25 ± 1.74 mm versus 23.89 ± 1.31 mm, p < 0.001) and had a flatter cornea than control eyes (mean keratometry 41.78 ± 1.80 diopters (D) versus 43.05 ± 1.51 D, p < 0.001). Corneal astigmatism was greater and the central cornea was thinner in MFS eyes (530.14 ± 41.31 μm versus 547.02 ± 39.18 μm, p < 0.001). MFS eyes were more myopic than control eyes (spherical equivalent -2.16 ± 3.75 D versus -1.17 ± 2.58 D, p < 0.001). Visual acuity was reduced (0.13 ± 0.25 logMAR versus 0.05 ± 0.18 logMAR, p < 0.001) and intraocular pressure was lower in MFS eyes (14.6 ± 3.4 mmHg versus 15.1 ± 3.2 mmHg, p = 0.01). Iris transillumination defects (ITD) were significantly more common in MFS eyes (odds ratio for MFS in the presence of ITD, 3.7). Ectopia lentis (EL) was only present in MFS eyes (33.4%). History of retinal detachment was significantly more common in MFS eyes. Glaucoma was equally common in both groups.ConclusionsITD and EL are most characteristic findings in MFS. ITD and corneal curvature should be studied as diagnostic criteria for MFS. Visual acuity is reduced in MFS. MFS patients need regular eye exams to identify serious ocular complications.
ABSTRACT.Purpose: There is evidence that ocular blood flow plays a critical role in the clinical course of glaucoma. Any reduction in ocular blood flow due to topical antiglaucoma treatment should therefore be avoided. This study aimed to evaluate the short-term effect of local latanoprost application on ocular hemodynamics. Methods: Intraocular pressure (IOP), ocular pulse amplitude (OPA), ocular pulse volume (OPV), systemic blood pressure, heart rate and the pulsatile component of ocular blood flow (POBF) were recorded using a pneumotonometer linked to the Langham Ocular Blood Flow System in 24 patients in a prospective, open-label study before and after 1 week of topical latanoprost application in both eyes. Twenty of the subjects had primary open-angle glaucoma and four had ocular hypertension. Results: After 1 week of latanoprost treatment, IOP decreased significantly 6.2 ∫ 2.9 mmHg in OD (P ∞ 0.001) and 6.2 ∫ 3.2 mmHg in OS (P ∞ 0.001). Pulsatile OBF increased significantly by 201.2 ∫ 167.4 mL/min in OD (P ∞ 0.001) and 203.8 ∫ 187.3 mL/min in OS (P ∞ 0.001). Ocular pulse amplitude and OPV showed statistically significant increases (P ∞ 0.05 and P ∞ 0.001 respectively). Blood pressure and heart rate did not change significantly. Conclusion: Our results indicate that 1 week after latanoprost application, POBF, OPA and OPV were significantly increased in the eyes treated. More information on the perfusion of the optic nerve head is needed before the relevance of these findings to optic nerve head blood flow can be interpreted correctly.
In this study, no significant increase in macular thickness and no other adverse effects were present. Furthermore, SLT was found to significantly lower IOP in glaucoma patients in addition to local therapy. In conclusion, SLT has a good ability to reduce IOP with a minor risk of adverse effects.
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.
