Eyes of patients with DM showed decreased CVI with no corresponding change in choroidal thickness. Image binarization may be potentially useful as a tool to assess choroidal structures and vasculature.
There is a relatively high prevalence of depression (30%) and anxiety disorders (64%) among glaucoma patients in Singapore. Female glaucoma patients are more likely to suffer from depression. Other risk factors for depression include higher cup-disc ratio, higher logMAR BCVA, lower MD, and a lower mean VFQ25 score. Risk factors for anxiety disorder include lower MD and lower mean VFQ25 score. Ophthalmologists could consider use of the VFQ25 as an assessment for impairments in QOL in a glaucoma patient. If a glaucoma patient is at high risk of depression or anxiety disorder, a multidisciplinary management approach involving ophthalmology and psychiatry may be required.
BackgroundThe aim of this study was to evaluate the efficacy and safety of topical ganciclovir 0.15 % gel in the management of patients with cytomegalovirus (CMV) anterior uveitis.ResultsThis was a retrospective cohort study of the disease course of 31 patients (33 eyes) with aqueous polymerase chain reaction (PCR) positive for CMV. Data from a total of 160 episodes of anterior uveitis flare for 20 years, dating from December 1992 to December 2012, was collected. All patients were treated with concomitant topical anti-inflammatory medication. The disease course of each eye was analysed before and after the use of topical ganciclovir 0.15 %. The mean age at initial presentation of anterior uveitis was 57.5 ± 12.6 years. Twenty-eight (90.3 %) patients were Chinese. Patients on topical ganciclovir gel had a statistically significant fewer episodes of uveitis flare per person year (median −0.88 episodes/person years, p = 0.029). The time-to-quiescence was not significantly affected by topical ganciclovir use (median −1.25 days, p = 0.610). In the survival analysis using the Cox regression model, the use of topical ganciclovir was associated with a lower risk of recurrence, but this was not statistically significant (hazard ratio = 0.857, 95 % CI 0.543–1.36, p = 0.511). The overall median time-to-recurrence was 290 days (95 % CI 113 to 274 days) and 164 days (125 to 404 days) (p = 0.492), with and without topical ganciclovir, respectively.ConclusionsTopical ganciclovir may be beneficial in reducing the frequency of recurrence in patients with CMV anterior uveitis, but it was not statistically associated with prolonging the time-to-recurrence. The time-to-quiescence was also not significantly affected by topical ganciclovir. Prospective studies with a larger number of patients would be required to verify our findings.
The study highlighted the importance of combining both structural and functional assessments in glaucoma. Current imaging technology demonstrated limited usefulness for event diagnosis due to the persistent difficulties of defining structural and functional loss in glaucoma, thus highlighting the need for new glaucoma assessment techniques. Short-term didactic teaching programs may only result in limited improvement of glaucoma diagnostic ability in optometrists, and hence, it may need to be combined with long-term and/or non-didactic training components to obtain a greater effect.
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.
