Treatment of type I ROP with intravitreal bevacizumab or laser photocoagulation according to retinal zone
AimsTo investigate the outcome of intravitreal bevacizumab (IVB) compared with laser photocoagulation in type I retinopathy of prematurity (ROP).MethodsCase records of 54 consecutive very low birth weight (VLBW) infants with type I ROP (posterior ROP, n=33; peripheral zone II, n=21) who were treated either with IVB (n=37) or laser photocoagulation (n=17) between 2011 and 2015 were retrospectively evaluated.ResultsPatients with posterior ROP displayed significantly faster regression of active ROP within 12 days (range 9–15 days) if treated with IVB compared with laser photocoagulation, where active ROP regressed within 57 days (range 28–63 days) (p>0.001). No difference was observed in peripheral zone II.Five of seven patients (12%) who developed a recurrence in both eyes after IVB required additional laser photocoagulation within a mean of 12.7 weeks (11.3–15.6 weeks) after the previous treatment. After laser photocoagulation one patient with posterior ROP developed macular dragging and another patient developed a temporary exudative retinal detachment in both eyes. 12 months after treatment the spherical equivalent was not statistically significant different between IVB and laser photocoagulation in posterior ROP patients. However, IVB lead to a significant lower spherical equivalent in infants with posterior ROP (+0.37 dioptres, range −0.5 to +1.88 dioptres) compared with peripheral zone II (+3.0 dioptres range +2.0 to +4.0 dioptres, p<0.001).ConclusionsIVB leads to faster regression of active ROP in infants with posterior ROP compared with laser photocoagulation. Spherical equivalent after 12 months was comparable in those treated with IVB and laser photocoagulation, but it was significantly lower in posterior ROP than in peripheral zone II.
Does ocriplasmin affect the RPE–photoreceptor adhesion in macular holes?
Background To evaluate the anatomical outcome of patients after vitrectomy due to persisting symptomatic vitreomacular traction (VMT), including full-thickness macular holes (FTMHs) of less than 400 µm, after ocriplasmin treatment. Methods Retrospective, single centre, consecutive interventional case series. Patients were treated with a single intravitreal injection of ocriplasmin (Jetrea, Thrombogenics Inc, USA, Alcon/Novartis EU). Main outcome measures: resolution of VMT, closure of FTMH and anatomical outcome of vitrectomy after unsuccessful treatment with ocriplasmin. Results Five patients were treated with ocriplasmin injection. VMT persisted in all but one case. Four patients underwent pars-plana vitrectomy (PPV) for treatment of persistent VMT and FTMH (n=2, size of macular hole <400 µm) in spectral-domain optical coherence tomography (SD-OCT). FTMHs were closed in both cases within the first week postoperatively. After PPV, in three eyes newly developed subretinal fluid was detected, which persisted up to several months postoperatively. Conclusions Data on ocriplasmin remain controversial. We report on four cases with resolution of VMT following PPV after unsuccessful ocriplasmin treatment. Newly developed subretinal fluid has been described after ocriplasmin treatment, predominantly in cases with resolution of VMT. We also detected this newly developed subretinal fluid after vitrectomy, which persisted for several weeks up to 7 months in two cases with FTMHs. This may be attributable to loosening of the photoreceptor complex due to enzyme activity of ocriplasmin. Long-term effects of ocriplasmin are still to be evaluated using SD-OCT.
Retrospective contralateral study comparing Descemet membrane endothelial keratoplasty with Descemet stripping automated endothelial keratoplasty
Purpose In this retrospective study, the visual outcomes and postoperative complications after Descemet stripping automated endothelial keratoplasty (DSAEK) and Descemet membrane endothelial keratoplasty (DMEK) in the fellow eye were compared. The patient’s satisfaction was evaluated. Methods A retrospective analysis of 10 patients, who underwent DSAEK in one eye and DMEK surgery in their fellow eye, was performed. Intraoperative and postoperative complications were recorded. Visual and refractive outcomes were evaluated, including higher-order aberrations (HOA) and contrast thresholds. A subjective questionnaire was used to evaluate patient satisfaction. Results Best-corrected visual acuity (BCVA) was significantly better in DMEK when compared with DSAEK (0.16±0.10 vs 0.45±0.58 logMAR, P =0.043). Contrast threshold was significantly higher after DMEK than after DSAEK (0.49±0.23 vs 0.25±0.18, P =0.043). Post-keratoplasty astigmatism, mean spherical equivalent, and HOA did not differ. Nine out of ten patients preferred the DMEK procedure. Visual outcome (4.80±1.14 vs 4.50±1.58, P =0.257), surgery associated pain and burden (DMEK: 1.30±0.48 vs DSAEK: 1.30±0.48, P =1.0), estimated time for recovery and rehabilitation (27.6±54.0 vs 24.9±54.8 days, P =0.173), and mean patient satisfaction (5.40±0.84 vs 5.00±1.05, P =0.257) were evaluated equally. Conclusion Patient satisfaction reached high, equal values after DMEK and after DSAEK. Nevertheless, patients preferred DMEK, if given a choice. Reasons for the preference may include better uncorrected and BCVA, and especially a better contrast sensitivity.
Trabeculectomy ab interno (trabectome): yet another possibility in the treatment of uncontrolled glaucomatocyclitic crisis under systemic valganciclovir therapy?
Purpose To assess the outcome of trabectome surgery in the treatment of glaucomatocyclitic crisis (Posner–Schlossman syndrome) in patients with uncontrolled intraocular pressure (IOP). Patients/Methods Trabectome surgery was performed in seven patients with diagnosed glaucomatocyclitic crisis and uncontrolled IOP where cytomegalovirus DNA was verified by polymerase chain reaction in aqueous humour samples. All patients were treated with oral valganciclovir. After surgery the patients were followed-up for 12 months. Results Mean IOP before trabectome surgery was 40±10 mm Hg (range 33–58 mm Hg). The mean number of antiglaucoma medication prior to surgery was 3.1±0.4. By the end of the 12 months, IOP in all patients was reduced to normal level (13±1 mm Hg) and their antiglaucoma medication was decreased to 0.8±1.1. No recurring attack of glaucomatocyclitic crisis occurred. Discussion In addition to oral valganciclovir therapy, trabectome surgery seems to be a reliable and effective tool for the management of glaucomatocyclitic crisis with uncontrolled IOP.
Vitrectomy with and without encircling band for pseudophakic retinal detachment with inferior breaks: VIPER Study Report No. 3
PurposeTo test if an encircling band improves outcomes in vitrectomy for pseudophakic retinal detachment (PRD) with inferior or with multiple (4 or more) breaks.MethodsSubgroup analysis of a prospective randomized controlled multicenter trial in patients with uncomplicated PRD assigned either to 20 G vitrectomy plus encircling band (group E1), or 20 G vitrectomy without any buckle (group C), or 23/25 G vitrectomy without any buckle (group E2). The primary endpoint was defined as no indication for any retina reattaching procedure during the review period of 6 months. One hundred out of 257 patients were identified with inferior breaks and 63 patients had 4 or more breaks.ResultsIn patients with retinal breaks between 5:00 and 7:00, treatment was successful in 77.4% (24/31, treatment arm E1) versus 57.1% (16/28, treatment arm C) (p = 0.301, odds ratio (OR) 1.83, 95% confidence interval (CI) 0.48 to 7.17). In patients with multiple breaks, success rates were 68.2% (15/22, E1) versus. 72.4% (21/29, C, p = 0.46, OR 0.52, CI 0.08–3.65).ConclusionCombining an encircling band with vitrectomy in patients with pseudophakic retinal detachment and inferior or multiple breaks does not significantly improve primary anatomical success in comparison to treatment with 20 G or 23/25 G vitrectomy alone.
Leukocyte-Mediated Endothelial Cell Injury and Death in the Diabetic Retina
Endothelial cell death is a hallmark of diabetic retinopathy. Its occurrence is required for the formation of acellular (devitalized) capillaries, lesions that produce irreversible retinal ischemia through their inability to support blood flow. The mechanisms underlying diabetic retinal endothelial cell injury and death remain largely unknown. The current study demonstrates that adherent leukocytes are temporally and spatially associated with retinal endothelial cell injury and death within 1 week of streptozotocin-induced experimental diabetes in rats. Moreover, the antibody-based neutralization of intercellular adhesion molecule-1 and CD18 is shown to prevent both leukocyte adhesion and retinal endothelial cell injury and death. These data highlight the central and causal role of adherent leukocytes in the pathogenesis of diabetic retinopathy. They also underscore the potential utility of anti-intercellular adhesion molecule1- and anti-CD18-based therapies in the treatment of diabetic retinopathy, a newly recognized inflammatory disease.
Corynebacterium macginleyi: a conjunctiva specific pathogen
BACKGROUND Although non-diphtherial corynebacteria are ubiquitous in nature and commonly colonise the skin and mucous membranes of humans, they rarely account for clinical infection. METHODS AND RESULTS 10 patients with unilateral conjunctivitis are described in whichCorynebacterium macginleyi was isolated. This species has only recently been reported to be exclusively isolated form ocular surfaces. C macginleyi was uniformly susceptible to topical antibiotics commonly used in ophthalmology. CONCLUSION Despite the fact that the pathogenicity of C macginleyiis not yet assured, this micro-organism should be recognised as a potential cause of bacterial superinfections. Appropriate antibiotic therapy leads to its elimination and resolution of the conjunctivitis.
Autologous translocation of the choroid and RPE in age-related macular degeneration: 1-year follow-up in 30 patients and recommendations for patient selection
Aim To evaluate the long-term (1 year) functional and anatomical outcome of autologous translocation of peripheral choroid and retinal pigment epithelium (RPE) in 30 patients with age-related macular degeneration (AMD). Methods After the extraction of the neovascular complex, an autologous peripheral full-thickness graft of RPE and choroid was positioned under the macula. Functional tests included ETDRS vision, reading (Radner test), and microperimetry (scanning laser ophthalmoscope). Fluorescein, indocyanine green angiography, and autofluorescence were monitored. Results Preoperative visual acuity ranged from 20/40 to 20/800 (0.3–1.6 log MAR). Vision ranged from 20/25 to LP (0.1–2.1 log MAR) 1 year after surgery, with stabilization in six eyes, an increase in five eyes, and a decrease in 19 eyes. Deterioration mostly occurred within the first 3 months after surgery. In patients who demonstrated vascularization of the graft after 3 months, this persisted up to 12 months as did fixation when initially stable. Autofluorescence decreased significantly from 6 to 12 months postoperatively. Eleven cases showed a recurrence of choroidal neovascularization (CNV) within this period. Conclusion Patch translocation results in a viable graft. There is no evidence of graft failure within a 1-year follow-up. Nevertheless, there is risk for late CNV formation originating from the edges of the excision side of the CNV and growing peripheral to the graft.
