This study aimed to evaluate the long-term efficacy and safety of infliximab (IFX) and cyclosporine (CsA) combination therapy for refractory uveoretinitis in Behçet's disease (BD). Patients and methods: The study involved a retrospective review of the medical records of 11 patients with Behçet's uveoretinitis refractory to conventional treatment who had been treated with IFX+CsA combination therapy. The frequency of ocular inflammatory attacks and a Behçet's disease ocular attack score 24 (BOS24) were used as indices for the evaluation of efficacy during each 6-month period prior to and following initiation of therapy. For the assessment of safety, adverse events (AEs) were recorded throughout the treatment period. Results: The patients had received IFX+CsA combination therapy for 5.6±2.3 years. The frequency of ocular attacks per 6-month period decreased markedly from 2.9±1.6 during the baseline period to 0.6±0.9 during months 1-6, 0.5±0.9 during months 7-12, 0.3±0.5 during months 13-18, 0.3±0.7 during months 19-24, and 0.0±0.0 thereafter (P=0.003). The BOS24 score per ocular attack significantly decreased from 5.2±2.4 during the baseline period to 1.5±2.1 during months 1-6, 1.7±3.1 during months 7-12, 1.6±2.9 during months 13-18, and 0.4±1.0 during months 19-24 (P=0.002). No serious AEs were observed, with the exception of urinary tract infection and cataract progression. Two patients exhibited transient elevation of the serum creatinine level, which was normalized following a reduction in the dose of CsA. Conclusion: For refractory Behçet's uveoretinitis, IFX+CsA combination therapy offers a promising treatment option as it appears to have an acceptable safety profile and can reduce the frequency and severity of ocular inflammatory attacks over a long period of time.

Purpose To evaluate the characteristics of posterior vitreous cells in patients with uveitis on the classification basis using spectral domain optical coherence tomography (SD-OCT). Methods In this retrospective chart review, all eyes were classified into three groups: infectious uveitis (IFU, n=7), noninfectious granulomatous uveitis (NIGU, n=13), and noninfectious nongranulomatous uveitis (NINGU, n=13). We measured the size, number, and density of vitreous hyperreflective particles in the posterior vitreous area that was defined as the space between the vitreous top and the internal limiting membrane on OCT. The correlations between vitreous haze and vitreous particles were also evaluated. Results Thirty-three eyes from 23 patients with active posterior uveitis were included. IFU had significantly more particles than NIGU and NINGU ( P =0.03 and P <0.001, respectively). The vitreous particle density was higher in IFU than in NIGU and NINGU ( P =0.03 and P =0.003, respectively). The mean largest particle size was greater in IFU and NIGU than in NINGU ( P =0.01 and P =0.03, respectively). The median vitreous haze of 2+ in IFU, 1+ in NIGU and NINGU showed no significant difference among three groups ( P =0.21). Conversely, the correlation of the largest particle size with vitreous haze was significant at ρ = 0.44 ( P =0.01). Conclusion SD-OCT may be useful for assessing ocular inflammation based on morphological characteristics of vitreous particles on the uveitis classification basis.

The efficacy of adalimumab in patients with noninfectious intermediate, posterior and panuveitis (NIPPU) has been assessed based on clinical findings obtained by conventional biomicroscopy. In this study, we utilised enhanced depth imaging optical coherence tomography (EDI-OCT) and attempted to investigate whether choroidal imaging parameters obtained by EDI-OCT are helpful in monitoring disease activity following the initiation of adalimumab therapy in eyes with refractory NIPPU. Our data indicates that the efficacy of adalimumab therapy could be better monitored by subfoveal choroidal thickness than the choroidal stromal index defined as the proportion of stromal area to the total choroidal area stromal area. From the results of subgroup analysis, Vogt-Koyanagi-Harada disease is likely to be most suitable for EDI-OCT evaluation.

Background: Since the advent of 27-gauge microincision vitrectomy system a decade ago, evidence regarding the feasibility, safety, and effectiveness of 27-gauge pars plana vitrectomy (PPV) has increased.Aim: To assess the effectiveness and safety profile of 27-gauge PPV for various vitreoretinal conditions associated with uveitis.Methods: We retrospectively investigated 73 consecutive cases that underwent primary 27-gauge PPV for uveitis-related ocular disorders between October 2014 and April 2021. The primary outcome measures were mean change in logMAR best-corrected decimal visual acuity (BCVA) pre-operatively to 3 months post-operatively, the proportion of BCVA improvement category defined as the degree of logMAR BCVA difference (“improved” [≤−0.3], “unchanged” [−0.3 to 0.3], and “worsened” [≥0.3]) pre-operatively to 3 months post-operatively, the mean change in intraocular inflammation scores pre-operatively to 3 months post-operatively; and intraoperative and post-operative complications.Results: The mean logMAR BCVA significantly improved from 0.69 pre-operatively to 0.42 at 3 months post-operatively (P = 0.017). The percentages of eyes with “improved,” “unchanged,” and “worsened” BCVA at 3 months post-operatively were 37, 50, and 13%, respectively. The mean anterior chamber cell score was 0.6 pre-operatively and 0.2 at 3 months post-operatively (P = 0.001), the mean anterior chamber flare score was 0.4 pre-operatively and 0.1 at 3 months post-operatively (P = 0.004), and the mean vitreous haze score was 1.9 pre-operatively and 0.1 at 3 months post-operatively (P &lt; 0.001). Surgery-related complications occurred in 35 (48%) eyes, 68% of which were related to intraocular pressure and transient.Conclusions: Given its risk–benefit profile, 27-gauge PPV is a promising option for the treatment of vitreoretinal disorders in uveitis.

Microhook trabeculotomy (μLOT), recently developed by Tanito belongs to minimally invasive glaucoma surgery and contributes to intraocular pressure (IOP) control in eyes with glaucoma resistant to medical therapy. In this study, we aimed to investigate the effectiveness and safety of μLOT for uveitic glaucoma. The medical records of consecutive 36 eyes from 30 patients who underwent μLOT and were followed up over post-operative 1 year were reviewed. The surgical success (IOP = 5–20 mmHg and ΔIOP ≥ 20% with additional anti-glaucoma drugs) was achieved in 67% of eyes at post-operative 12 months. The median IOP significantly decreased from 30.5 mmHg pre-operatively to 15 mmHg at 12 months post-operatively (p = 0.001), and the median glaucoma drug score changed from 5 pre-operatively to 2.5 at 12 months post-operatively (p = 0.301). Intraocular inflammation scores at post-operative 6 weeks did not show a significant worsening as compared to pre-operatively, and 8 (22%) eyes exhibited exacerbation of inflammation during the 12-month follow-up period. Post-operative complications were confirmed in 58% of eyes, but most of them were mild and transient or successfully managed. With its favorable benefit–risk profile, μLOT would be an option worth considering as the first glaucoma surgery for uveitic glaucoma.

We report and compare 2 cases of open globe injury with foveal damage incurred while mowing. Case 1 is a healthy 67-year-old man presenting with an intraocular metallic foreign body and eye pain in his right eye after using a mower. The foreign body perforated the cornea’s inferior area and damaged the foveal centralis, leading to central scotoma and decreased visual acuity. 27G pars plana vitrectomy was performed, and the final corrected decimal visual acuity was 0.1, but the visual field was preserved, except for the central scotoma. Case 2 is a healthy 50-year-old man presenting open globe injury with an intraocular metallic foreign body while using a mower. The foreign body damaged the fovea and triggered extensive retinal detachment. One month after surgery, proliferative vitreoretinopathy occurred, requiring additional surgery. The final corrected decimal visual acuity dropped to 0.05, resulting in an extensive visual field defect. Both cases of eye trauma were caused by mower injury, but the visual function outcomes differed with the size of the foreign body and the injury severity at the time of onset. Mower eye trauma is preventable, and efforts to educate users on safety measures are needed.
