Traffic accident-related open globe injuries had better visual outcomes than common open globe injuries. Visual outcomes in patients with traffic accident-related open globe injuries were related to the initial visual acuity. No eyes developed endophthalmitis in patients with traffic accident-related open globe injuries.
Aims: The purpose of this study was to evaluate the effect of pulse duration on the expression of inflammatory cytokines in the murine retina after laser photocoagulation treatment with a PASCAL® pattern scan laser photocoagulator and conventional laser treatment. Methods: Retinal scatter laser photocoagulation was performed on C57BL/6J mice using a short pulse (10 ms) with a PASCAL laser or conventional settings (100 ms) with a multicolor laser. Eyes were enucleated before treatment (control) and 1 day, 3 days and 7 days after treatment. The levels of inflammatory cytokines (i.e., VEGF, MCP-1, RANTES and IL-6) in the retina/choroid were quantified by an ELISA. The expression patterns of VEGF and macrophages (i.e., F4/80) in the retina/choroid were evaluated by immunohistochemistry. Results: The levels of RANTES, IL-6 and MCP-1 after PASCAL and conventional laser treatments were significantly elevated compared with controls (p < 0.05). Conventional laser treatment, but not PASCAL treatment, resulted in the up-regulation of VEGF. RANTES and IL-6 levels on day 1 and MCP-1 levels on day 3 in the sensory retina were also significantly up-regulated with conventional laser treatment compared with PASCAL treatment (p < 0.05). Immunohistochemical analysis showed that PASCAL treatment was associated with lower VEGF and F4/80 expression levels compared with conventional laser treatment. Conclusions: Our data suggested that the short pulse duration induced fewer inflammatory cytokines in the sensory retina compared with the conventional pulse duration. Short pulse laser photocoagulation with the PASCAL may prevent macular edema after panretinal photocoagulation.
PurposeThe aim of this study is to report the 6-month results after one intravitreal ranibizumab (IVR) injection followed by pro re nata dosing for macular edema (ME) after branch retinal vein occlusion.Patients and methodsThe inclusion criteria included a minimal patient age of 18 years, 20 letters or more best-corrected visual acuity (BCVA) (Early Treatment Diabetic Retinopathy Study [ETDRS] score, 77 letters or less), and central retinal thickness (CRT) of 250 microns or more. The primary outcome measure was the mean BCVA change from baseline at month 6; the secondary outcomes were mean changes in CRT, residual ME, and microaneurysm formation.ResultsTwenty patients were enrolled from March 2014 through October 2016 at Nagoya City University Hospital. The baseline mean ETDRS letters and CRT were 63.1 and 500 microns, respectively; mean time from symptom onset to initial therapy was 1.80 months; and mean ETDRS gain and CRT reduction were 15.2 letters and 230 microns, respectively. The percentages of patients with Snellen equivalent BCVAs of 20/40 (70 ETDRS letters) or better and 20/20 (85 ETDRS letters) were 90% and 15%, respectively. Residual ME and microaneurysms were observed in 85% and 35% of patients. Microaneurysm formation was associated with delayed initial therapy.ConclusionPrompt initiation of IVR injection provided a better visual prognosis at month 6 and suppressed the microaneurysm formation.
BackgroundThe purpose of this study is to report wide-field angiography findings before and after steroid therapy in a case with bilateral Vogt-Koyanagi-Harada (VKH) disease.ResultsA 44-year-old woman presented with bilateral blurred vision and metamorphopsia accompanied by symptoms of headache and tinnitus. The baseline best-corrected visual acuity was 20/20 in both eyes. Ophthalmic examination revealed a shallow anterior chamber and panuveitis accompanied by multiple serous retinal detachments in both eyes and ciliochoroidal detachments in the left eye. Wide-field fluorescein angiograms showed hyperfluorescene indicating pooling corresponding to multiple serous retinal detachments in the posterior lesion and vascular leakage in the peripheral retina and choroid, resolved after steroid tapering therapy. Interestingly, wide-field indocyanine angiograms revealed narrowing of choroidal vessels in the acute phase and its normalization with resolution of inflammation after the therapy.ConclusionsEyes with Vogt-Koyanagi-Harada disease had peripheral chorioretinal vascular leakage and choroidal vessel narrowing in the acute phase. Wide-field angiography is a useful tool to reveal peripheral chorioretinal findings and assess diameters and density of choroidal vessels.
