Differentiated Approach to Strategies of Surgical Treatment of Idiopathic Macular Holes

Background. 25G or 27G three-port vitrectomy, followed by staining and removal of the internal limiting membrane with vitreous cavity air or gas tamponade, is one of the main modern vitreoretinal surgery principles for primary macular holes. However, not all patients manage to obtain a functional outcome when the anatomical outcome is achieved. Purpose. To present clinical cases of surgical treatment of idiopathic macular holes (IMH) exhibiting a differentiated approach.Matherials and methods. This article analyzes clinical cases of four patients with primary idiopathic macular holes, differing in terms of development, hole diameter and the presence of comorbidities. Results. The results of surgical treatment were evaluated 14 days and 1 month after surgery. In all clinical cases, surgical treatment resulted in a positive anatomical outcome by blocking a retinal defect. Best corrected visual acuity increased, on average, from 0.08 ± 0.05 to 0.4 ± 0.05.Conclusion. The analysis of the presented clinical cases clearly demonstrates the need for a timely and differentiated approach to the treatment of patients with IMH, that considers etiology of the pathological process, period of its existence as well as concomitant and general somatic pathologies.

One year outcome and predictors of treatment outcome in central serous chorioretinopathy: Multimodal imaging based analysis

Purpose To evaluate the follow up and treatment outcome of central serous chorioretinopathy (CSCR) based on the new multimodal imaging-based classification and identify the predictors for anatomic and visual outcome. Methods Retrospective, multicentric study on 95 eyes diagnosed with CSCR and a follow up of at least 12 months were included. Eyes with macular neovascularization, atypical CSCR or any other disease were excluded. Results At the baseline, observation was advised to 70% eyes with simple CSCR whereas photodynamic therapy (PDT) was performed in 49% eyes with complex CSCR. Over the follow up, decrease in CMT was significantly higher in simple CSCR as compared to complex CSCR ( P = 0.008) and the recurrences were significantly more in eyes with lower CMT at baseline ( P = 0.0002). Median time of resolution of SRF was 3 months and 6 months in simple and complex CSCR respectively ( P = 0.09). For the 12 months follow up, the median fluid free period was greater ( P = 0.03) while number of interventions performed was lesser in eyes with simple CSCR as compared to complex CSCR ( P = 0.006). Multiple regression analysis showed baseline best corrected visual acuity (BCVA) and baseline persistent SRF to be significantly predictive of BCVA and persistent SRF at 12 months ( P < 0.0001, 0.04) respectively. Conclusions Complex CSCR more often required PDT, was associated with shorter fluid free interval and longer time for SRF resolution. Baseline BCVA and persistent SRF were predictive of final visual and anatomical outcome. The new multimodal imaging based classification is helpful in establishing objective criteria for planning treatment approaches for CSCR.

One-year outcome of cystoid macular degeneration in central serous chorioretinopathy

Purpose: To study structural and functional outcomes of cystoid macular degeneration (CMD) in chronic central serous chorioretinopathy (CSCR). Methods: This retrospective study included 26 eyes having chronic CSCR with CMD who underwent either observation, photodynamic therapy (PDT), micropulse laser, or eplerenone therapy. Various optical coherence tomography parameters were analyzed at baseline and 1 year. Results: Number of eyes that maintained or gained vision after treatment was 63.1%, compared to a loss of 2.1 ± 1.1 lines in observation group. Sub-foveal large choroidal vessel responded to PDT ( p = 0.03); while CMT ( p = 0.035) and intra-retinal cystoid spaces (0.037) responded to eplerenone. Longer duration of the symptoms and round cystoid spaces were associated with a decrease in CMT ( p = 0.03) and decrease in cystoid spaces size ( p = 0.02) respectively on follow up. Conclusion: Treatment of eyes with CMD prevents further deterioration of vision. Round configuration of intra-retinal cystoid space has a better anatomical outcome.

Visual/anatomical outcome of diabetic macular edema patients lost to follow-up for more than 1 year

To investigate the visual/anatomical outcome of diabetic macular edema (DME) patients lost to follow-up (LTFU) for more than 1 year during intravitreal anti-VEGF treatment. A retrospective review of 182 treatment-naïve DME patients was performed. Among them, we identified patients LTFU for more than 1 year during anti-VEGF treatment. Visual acuity and anatomic outcomes at the first visit, last visit before being LTFU, return visit, and after re-treatment were analyzed and compared with those of DME patients with regular follow-up. Patients who had continuous follow-up visits were assigned to the control group. Sixty patients (33%) with DME were LTFU for more than 1 year during anti-VEGF treatment. Multivariate analysis revealed that the ratio of male (p = 0.004), diabetes mellitus (DM) duration less than 5 years (p = 0.015), and poor early anatomic response (p = 0.012) were higher compared to the control group. Eighteen patients returned to the clinic and received re-treatment. After re-treatment with anti-VEGF, central subfield thickness (CST) was significantly improved to the CST of before LTFU. However, visual acuity did not recover to the level before LTFU (0.63 ± 0.26 vs. 0.45 ± 0.28, p = 0.003). About thirty percent of DME patients were LTFU for more than 1 year. Permanent visual loss was observed in these LTFU patients. Patients with a high risk of LTFU such as male, early DM, and poor response after initial injections should be treated more aggressively to improve the visual outcomes.

A mitralis billentyű sebészete atrioventricularis septumdefektusban

Összefoglaló. A veleszületett szívbetegségek egyik gyakori formáját jelentő atrioventricularis septumdefektus korrekciós műtétjének kritikus pontja a közös atrioventricularis szájadék elválasztásával a mitralis billentyű kialakítása. A korrekció sikere számos anatómiai variáns függvénye, ezért nem lehet minden esetben a tökéletes anatómiai viszonyokat kialakítani. A fennmaradó billentyűstenosisok, regurgitatiók a későbbi életkorban progressziót mutatva olyan hemodinamikai kórképeket, keringési elégtelenséget okozhatnak, melyek további beavatkozásokat igényelhetnek. A mitralis billentyűnek az atrioventricularis septumdefektushoz társuló betegsége koraszülöttkortól aggkorig minden életkorban előfordul, más-más műtéti megoldást igényelve. A szerzők részletezik a különböző életkorokra vonatkozóan a napjainkban lehetséges és szükséges műtéti megoldásokat, sebészi kihívásokat. A mitralis billentyű műbillentyűre történő cseréjében a klasszikus sebészi megoldások mellett napjainkban új beavatkozásokként jelentős számban jelentkeznek a katéteres intervenciós és hibrid megoldások. A felnőttkort egyre nagyobb számban megélő betegek fokozott odafigyelést, speciális ellátást igényelnek a kardiológusoktól, szívsebészektől. Orv Hetil. 2021; 162(35): 1397–1401. Summary. The critical point of the atrioventricular septal defect correction is to separate the common atrioventricular orifice, which results in the reconstruction of the mitral valve. The success of the correction depends on many anatomical aspects, therefore a perfect anatomical outcome is not always possible. The remaining valvular stenoses and regurgitations, showing progression at a later age, may result in hemodynamic disorders and circulatory insufficiency that may require further interventions. Mitral valve disease associated with atrioventricular septal defect occurs at all ages from preterm to adulthood, requiring different surgical solutions. The authors detail the possible and necessary surgical solutions and surgical challenges at different ages. In addition to the classic surgical solutions, a significant number of catheter interventional and hybrid solutions are emerging as new interventions in the replacement of the mitral valve with an artificial valve. An increasing number of patients living in adulthood require increased attention and special care from cardiologists and cardiac surgeons. Orv Hetil. 2021; 162(35): 1397–1401.

Subretinal proliferation. What to do?

Purpose. Evaluation of treatment results retinal detachment complicated by subretinal PVR. Materials and methods. We examined 13 patients (13 eyes) with operated retinal detachment (RD), subretinal proliferative vitreoretinopathy (PVR). In the main group (7 eyes) with recurrence of retinal detachment RD was complicated by severe subretinal proliferation. Аll the patients underwent surgical treatment of retinal detachment with removal of the subretinal PVR; in the control group (6 eyes) subretinal proliferation was localized in the zone of the adjacent retina and its removal was not performed. Results. The compared groups did not differ in terms of age and gender, the axis length of the eye. Duration of the RD was more than 3 months. During the observation period of 6 months of patients both groups, in all cases, it was possible to achieve a fit of the retina. Conclusion. 1. Subretinal PVR should be removed when it is localized in the macular area, or when it leads to retinal detachment, preventing it from fitting with standard technical manipulations. 2. Potential of microinvasive vitreoretinal surgery allow to effectively eliminate subretinal PVR, complementing standard manipulations, with a good functional and anatomical result. Keywords: retinal detachment, proliferative vitreoretinopathy, anatomical outcome.

ANATOMICAL AND VISUAL OUTCOME OF COMBINED PHACO-VITRECTOMY VS VITRECTOMY ALONE

Introduction Separation of Neurosensory retina from RPE(Retinal Pigment Epithelium) is described as retinal detachment. Recently Pars plana vitrectomy has emerged as a preferred surgical treatment for management of uncomplicated primary rhegmatogenous retinal detachment. Various studies have evaluated the results of combined phaco-vitrectomy, the combined approach allows faster visual recovery and has cost effectivity for patient. The rationale of this study is to compare the anatomical and visual outcome of combined phacoemulsification and vitrectomy vs vitrectomy alone Materials and methods This prospective randomized controlled trial was performed at Eye Unit II Mayo Hospital Lahore (tertiary care eye hospital in Lahore), Pakistan from August 2019 to February 2020. 36 patients full filling the inclusion criteria were divided into two groups 18 patients each. Group A was of combined Phaco-vitrectomy and Group B was of vitrectomy only. The Mann-whitney test as test of significance was applied and P≤0.05 was considered statistically significant. Results BCVA done Pre-operatively for Group A and B, P-value was > 0.05 which was insignificant. Best corrected visual acuity at first week post operatively was significantly lower in patients in which we used gasses as internal tamponade as compared those in which we used silicon oil as tamponade. The BCVA at 1 month showed improvements in both groups, however the BCVA in group B was significantly lower than group A, P-value being < 0.05. The BCVA at 3 month showed improvements in both groups, however the BCVA in group B was significantly lower than group A, P-value being < 0.05. Anatomical Outcome was seen as weather retina was attached or detached. In Group A detachment was present in all follow-ups in 2/18 patients while in Group B detachment was present in all follow-ups in 3/18 patients. The P-value was >0.05 and thus the difference between two groups was insignificant. Conclusion visual acuity did not differ among the two groups preoperatively and on first follow-up at 1 week. The P value being >0.05 in both. However there was significant difference between the two group at 1 month and 3 months follow up, P value being < 0.05 in each. The visual acuity was significantly better in Group A i.e combined phaco- vitrectomy. For anatomical outcome no difference was seen between the groups. The P value was > 0.05. So the visual outcome of group A was significantly better than group B while the anatomical outcome was the same. Keywords Phacoemulsification, Three ports pars plana vitrectomy, best corrected visual acuity, retinal detachment.

Unassisted and multiple microcatheter coiling of distal basilar aneurysms: Outcomes and literature review

Purpose The best treatment for distal basilar artery aneurysms is controversial. We aimed to review our single-centre experience with coil embolisation of aneurysms at this location and compare it with the surgical and endovascular literature. Methods Forty-two aneurysms in a distal basilar location in 42 consecutive patients (15 ruptured and 27 unruptured) were treated endovascularly from 2010 to 2015. Unassisted single and multiple microcatheter coil embolisation alone was used in all cases. We studied our immediate and long-term anatomical results, operative complications, and outcome. Results The immediate angiographic results showed complete occlusion in 34 (81%), a neck remnant in seven (16.6%) and a residual aneurysm in one patient (2.4%). There were two thromboembolic events (4.7%) without clinical sequelae; therefore, the operative morbidity and mortality were zero. Three patients with ruptured aneurysms (7.1%) died due to complicated vasospasm. Thirty-nine patients (93%) had clinical and MR imaging follow-up (mean 32.3 months ± 18.6, range from 12 to 66 months). There was recanalization in 30.8% with a retreatment rate of 15.3% and no new bleedings. The aneurysm size was the most important predictor of early anatomical outcome and recurrence. Conclusion Unassisted and multiple microcatheter coiling is a safe treatment for distal basilar aneurysms. Early anatomical results and recurrence depend on the aneurysm size. Morbidity and mortality are lower and recurrence rates are higher in comparison with clipping or other adjunctive endovascular techniques.

Modified sewing machine technique in combination with lens aspiration and anterior vitrectomy for large iridodialysis repair

We describe the management of a large iridodialysis repair using the modified sewing machine technique and lens aspiration in a single setting in an eye with blunt ocular injury. We performed the lens aspiration first followed by iridodialysis repair. The technique was easy and fast, with good postoperative anatomical outcome.
