Ocular syphilis is seeing a worldwide resurgence. Although anterior uveitis and panuveitis were most common in this study, there was a large spectrum of ocular manifestations. Syphilitic uveitides can potentially cause severe loss of vision but are effectively treated by an appropriate regimen of penicillin.

Presenting symptoms and signs are related to the angiographic drainage of CCFs. Angiographic outcomes after embolization treatment may not always correlate with clinical outcomes.

Background/Aims: To highlight the potential ocular side effects of bisphosphonate therapy and the importance of a proper drug history in patients who present with uveitis. Methods: We report 2 cases of bilateral uveitis secondary to bisphosphonate therapy. Both patients were on nitrogen-containing bisphosphonates when they developed symptoms of bilateral anterior uveitis. A uveitis screen done in both cases was normal. Results: The uveitis in both patients resolved after discontinuation of the bisphosphonates, and there has been no recurrence of symptoms during the duration of the follow-up of 6 and 5 months, respectively. Conclusion: All patients receiving bisphosphonates who develop ocular signs and symptoms should be referred promptly to an ophthalmologist. The offending drug should be discontinued once the diagnosis is made, in order to prevent involvement of the contralateral eye and recurrent or chronic ocular inflammation. Patients who are susceptible to the nitrogen-containing bisphosphonates should be switched to the non-nitrogen-containing bisphosphonates.

Background/aimsTo assess the agreement in measuring retinal nerve fibre layer (RNFL) thickness between spectral-domain (SD; Cirrus HD, Carl Zeiss Meditec, USA) optical coherence tomography (OCT) and swept-source (SS; Plex Elite 9000, Carl Zeiss Meditec) OCT using an OCT angiography (OCTA) scanning protocol.Methods57 participants (12 glaucomatous, 8 ocular hypertensive and 74 normal eyes) were scanned with two OCT instruments by a single experienced operator on the same day. Circumpapillary RNFL thicknesses were automatically segmented for SD-OCT and manually segmented for SS-OCTA scans. Agreement of global RNFL thickness, as well as average thickness in four quadrants was assessed using intraclass correlation coefficients (ICCs).ResultsThere was excellent agreement in the inferior and superior quadrants and the global (all ICC >0.90), followed by good agreement in the temporal (ICC=0.79) and nasal (ICC=0.73) quadrants. The ICC values were similar in the subgroups except within the ocular hypertension group, where the nasal quadrant was less agreeable (ICC=0.31). SS-OCTA-derived RNFL thickness was on average 3 µm thicker than SD-OCT, particularly in the nasal (69.7±11.5 µm vs 66.3±9.3 µm; p<0.001) and temporal (75.6±13.7 µm vs 67.9±12.3 µm; p<0.001) quadrants.ConclusionsRNFL measurements taken with SS-OCTA have good-to-excellent agreement with SD-OCT, which suggests that the RNFL thickness can be sufficiently extracted from wide-field OCTA scans.
