We performed a systematic review on 3 major types of scleral-fixated intraocular lens (SFIOL) implantations and conducted subgroup analyses on pediatric population and subjects with Marfan syndrome.

Systematic review.

We performed a search in PubMed, Ovid MEDLINE, and Embase for English language articles with keywords "(sutured intraocular lens) OR (SFIOL) OR (sutureless intraocular lens) OR (glued intraocular lens) OR (intrascleral intraocular lens) OR (SFIOL)" through October 16, 2019. Articles reporting individual outcomes after SFIOL were included in this systematic review. Recorded outcome measures included intraoperative and postoperative complications, endothelial cell changes, and intraocular lens-related outcomes.

Our search yielded 217 papers. After removing duplicated and irrelevant reports, we included 57 articles involving 2624 eyes. The mean age at operation was 51.47 ± 25.62 years. Sutured SFIOL was most commonly reported in all subjects with Marfan syndrome and 92.87% of pediatric patients. The pooled intraoperative complication rate was 6.65%. Minor anterior chamber hemorrhage was the most common intraoperative (1.92%) and postoperative complication (13.93%). Optic capture was the top intraocular lens (IOL)-related complication (4.47%). WAY-309236-A chemical structure The overall mean endothelial cell loss was 8.95% at 16.77 ± 11.04 months. Overall 11.99% of SFIOLs were decentred with a mean distance of 0.49 ± 0.40 mm and a mean degree of tilt by 4.11 ± 3.03°.

Glued SFIOL had the fewest IOL-related complications and the lowest endothelial cell loss. Sutured SFIOL carried the highest IOL-related complications, whereas sutureless, glueless SFIOL was associated with the greatest endothelial cell loss.

To compare peripapillary perfused capillary density (PCD) on optical coherence tomography angiography among resolved acute angle-closure (AAC), primary open-angle glaucoma (POAG), and control eyes.

Prospective, cross-sectional, observational study.

All patients with resolved AAC or POAG of varying severity and controls were enrolled. We obtained 4.5 × 4.5 mm2 optical coherence tomography angiography images of the optic nerve head. PCD was analyzed using customized software with major vessel removal. Continuous variables were assessed using the analysis of variance and Bonferroni correction test. A marginal model of generalized estimating equations was used to adjust for confounding factors and interocular correlation.

The study included 44 eyes with resolved AAC (mean duration of elevated intraocular pressure, 8.1 ± 10.9 days), 69 eyes with POAG, and 49 control eyes. PCD showed a similar decrease between AAC and POAG eyes (P > 0.99). After adjusting for age and sex, the mean difference in global PCD between each of the POAG stage groups and the AAC group was the highest in the severe POAG group (-3.43; 95% confidence interval [CI], -11.38 to 2.52; P = 0.211), followed by the mild POAG (0.68; 95% CI, -3.26 to 4.62; P = 0.735) and moderate POAG (0.20; 95% CI, -5.21 to 5.61; P = 0.942) groups. The duration of increased intraocular pressure did not affect PCD (P = 0.258 and 0.168 for global and annular PCDs, respectively).

The degree of microvascular attenuation in AAC eyes was not different from that in POAG eyes.

Myopic traction maculopathy (MTM) is a complex disease affecting approximately 30% of eyes with pathologic myopia. A review of the history of treatment of MTM with success rates and limitations of different surgical techniques are reported.The pathogenesis, the definition and the management were clarified in a recent study(cit). The MTM Staging System (MSS) table summarizes all the stages of MTM offering insights on the pathogenesis and natural evolution of the disease.Guidelines of management of MTM were therefore proposed, but customized for each stage.Initial stages 1a and 2a, which define maculoschisis in the inner or inner-outer or only outer layers of the retina, should be observed. Stages 3a and 4a, defining macular detachment with and without associated schisis, should be treated with a macular buckle (MB).Stage 1b, which is a lamellar macular hole in a myopic eye, should be treated with pars plana vitrectomy (PPV) only in symptomatic cases. Stages 2b, 3b, and 4b should be treated with a MB and PPV inner or inner-outer or only outer layers of the retina, should be observed. Stages 3a and 4a, defining macular detachment with and without associated schisis, should be treated with a macular buckle (MB).Stage 1b, which is a lamellar macular hole in a myopic eye, should be treated with pars plana vitrectomy (PPV) only in symptomatic cases. Stages 2b, 3b, and 4b should be treated with a MB and PPV should be added in a second step only if the presence of a lamellar macular hole requires intervention to improve visual function.Stage 1c, which is a full thickness macular hole in a myopic eye, should be treated with PPV. Stages 2c, 3c and 4c should be treated with a combination of simultaneous MB + PPV to treat both the retinal pattern of schisis or detachment and the full thickness macular hole.Segmental absence of the intestinal musculature (SAIM) can cause intestinal perforation in adults. However, its prevalence and clinicopathologic features have not been well-described. This study aimed to determine the prevalence of SAIM-associated perforation and characterize its clinicopathologic features. We retrospectively examined 109 cases of intestinal perforation that underwent surgical resection from January 2009 to December 2019. SAIM was defined as the complete absence of the muscularis propria without extensive inflammation and fibrinous exudation around the perforation. SAIM was the second most frequent cause of perforation (26 cases 24%), the most frequent cause being related to diverticulitis (39 cases 36%). The most common site was the sigmoid colon (12 cases 46.2%). The younger group (aged below 65 y) exhibited more frequent perforation of the upper segments of the gastrointestinal tract (from the duodenum to the descending colon) than the older group (65 y and above) (P=0.0018). No patients developed recurrence.
