Abstract Background To investigate the efficacy and safety of continuous ab interno repairing of traumatic cyclodialysis cleft in severe ocular trauma using a 30-gauge (G) needle. Methods Fifteen patients (15 eyes) with traumatic cyclodialysis cleft admitted to the ocular trauma department of our hospital from July 2014 to December 2018 were included in this study. After the bulbar conjunctiva corresponding to the ciliary body was incised along the corneal limbus, an incision was made along the corneal limbus on the opposite side. A 30G needle with a 10–0 suture entered the anterior chamber from the incision and passed through the ciliary body with clefts and the sclera to fixate the ciliary body on the sclera wall with continuous mattress suture. The best corrected visual acuity (BCVA) and intraocular pressure (IOP) were observed preoperatively and postoperatively. In vivo ultrasound biomicroscopy (UBM) was performed to observe closure of cyclodialysis cleft before and after surgery. Results Fifteen patients successfully underwent continuous mattress suture for repair of cyclodialysis cleft. No bleeding and suture breakage were reported during surgery. After surgery, the UBM during follow-up showed satisfactory closure of the cyclodialysis cleft. The BCVA and IOP were improved to different degrees. The difference between the preoperative IOP and the postoperative IOP (1 week) was statistically significant (preoperative: 6.49 ± 0.98 mmHg, postoperative: 16.17 ± 4.65 mmHg, t = − 8.43, P < 0.05), and the difference between the preoperative IOP and the postoperative IOP (1 month) was also statistically significant (preoperative: 6.49 ± 0.98 mmHg, postoperative: 14.63 ± 3.63 mmHg, t = − 8.38, P < 0.05). Duration of outpatient follow-up was 3 to 12 months. No complications, including exposed knots, loose sutures, decompensation of corneal endothelium, sympathetic ophthalmia, endophthalmitis and choroidal detachment, were reported. Conclusion Continuous ab interno repairing of traumatic cyclodialysis cleft in severe ocular trauma using a 30G needle is a safe and effective procedure with simple operation, little tissue damage and few complications.

Background. Various techniques have been described for repairing cyclodialysis clefts, but there is no consensus regarding the optimal treatment. This study investigated the clinical efficacy of a novel surgical approach that is used to manage traumatic cyclodialysis. Methods. We prospectively enrolled 7 patients (7 eyes) with traumatic cyclodialysis of the concomitant lens and other vitreous diseases. Ultrasound biomicroscopy was used to diagnose cyclodialysis, and all eyes underwent pars plana vitrectomy with air endotamponade. The main outcome measures were postoperative anatomical success rates, best-corrected visual acuity (BCVA), and intraocular pressure (IOP). Results. All patients were male, and their age ranged from 46 to 64 years (mean: 54.3 years). After the surgical intervention, the extent of the cyclodialysis cleft ranged from 1 to 4 clock hours (mean: 2.3 clock hours) and the detached ciliary body of all cases was completely restored; the anatomical success rate was 100%. The BCVA significantly increased from 1.40 ± 0.49 to 0.42 ± 0.31 (P = 0.002). The IOP increased from 8.91 ± 1.77 to 14.67 ± 6.38, but the difference was not significant (P = 0.056). The postoperative IOP of most patients was temporarily elevated or lowered after surgery. At the last follow-up, there were still two abnormal cases, including one with ocular hypertension and one with hypotony. Conclusions. This study revealed that vitrectomy with air endotamponade is an effective and minimally invasive alternative surgical approach for small traumatic cyclodialysis clefts.

Extramedullary plasmacytoma of the iris and ciliary body is extremely rare. We present a case which was misdiagnosed as granulomatous uveitis with neovascular glaucoma, and underwent a trabeculectomy with mitomycin-c along with iris biopsy. The post-operative period showed early bleb failure and catastrophic growth of the suspected mass. Histopathological examination revealed a diagnosis iris plasmacytoma. Subsequent ultrasound biomicroscopy showed involvement of the iris and ciliary body. A prompt systemic workup was done, and an associated systemic plasma cell dyscrasia was ruled out. The affected eye was enucleated, and the patient remains disease free at the end of 3-year follow-up.

ABSTRACT Objective:  To assess camouflage effects by concealment of postorthodontic white-spot lesions (WSLs) to sound adjacent enamel (SAE) achieved over 12 months with resin infiltration (Icon, DMG, Hamburg, Germany). Methods:   Twenty subjects (trial teeth nteeth = 111) who had received resin infiltration treatment of noncavitated postorthodontic WSLs were contacted for a 1-year follow-up assessment of CIE-L*a*b* colors (T12). Color and lightness (CIE-L*a*b*) data for WSLs and SAE were compared to baseline data assessed before infiltration (T0) and those assessed after 6 months (T6), using a spectrophotometer. The target parameter was the difference between the summarized color and lightness values (ΔEWSL/SAE). Intergroup (WSL, SAE) and intertime comparisons (T0 vs T6, T12) were performed using paired t-tests at a significance level of α = 5%. Results:  Nine subjects (trial teeth nteeth = 49; male/female ratio 5/4; age range 13–19 years) were available at T12. After the highly significant reduction of ΔEWSL/SAE discrepancies between T0 and T6, analysis of 12-month records revealed color and lightness discrepancy of WSL vs SAE that was significantly decreased compared with baseline, indicating an assimilation of WSL color to SAE appearance after infiltration, while an additional reduction of discrepancies between T6 and T12 was not significant. Conclusion:  As color and lightness characteristics of the Icon infiltrant as well as the esthetic camouflage effects achieved by WSL infiltration were not altered significantly or clinically relevant after 12 months, the method of resin infiltration can be recommended for an enduring esthetic improvement of postorthodontic WSL.

Abstract Background: Recently, a new type of foldable capsular vitreous body (FCVB) has been developed for clinical application to fill the vitreous cavity with vitreous substitutes. It may be an ideal substitute for the vitreous body in eyes with severe retinal detachment. The aim of this study was to assess the application of a foldable capsular vitreous body (FCVB) in the treatment of severe ocular trauma and silicone oil (SO) dependent eyes.Methods: A retrospective analysis was performed on the clinical application of FCVB in the treatment of severe ocular trauma and SO dependent eyes. The results of best-corrected visual acuity and intraocular pressure (IOP) evaluation, B-scan ultrasonography or color Doppler ultrasonography, ultrasound biomicroscopy, and anterior segment photography were recorded during follow-up. A paired t-test was used to compare the difference in IOP before and after FCVB implantation. Results: Seven eyes of seven patients were included in the 6 months follow-up. In all cases, B-scan ultrasonography and ultrasound biomicroscopy showed that FCVB adapted closely to the globe wall and ciliary body, thus supporting the retina. Visual acuity did not improve, except in one case from LP to HM. The mean±SD IOP was 9.29±1.60mmHg prior to FCVB implantation and 10.43±0.98mmHg after implantation, with no significant difference between these measurements (P=0.066). Five of the seven patients developed differing degrees of corneal opacity and keratopathy. Conclusions: FCVB implantation may be a safe and effective method for the treatment of severe ocular trauma and SO dependent eyes. However, corneal opacity and keratopathy are potential serious complications after surgery. Appropriate case selection and proper surgical time require further investigation.

Introduction. Ultrasound biomicroscopy (UBM) is a non-invasive diagnostic procedure, developed in order to achieve better visualization of the anterior segment of the eye. The first clinical images were made in March 1990. The use of UBM at the Institute for Eye Diseases, Clinical Centre of Serbia, began in February 2007. Outline of Cases. Due to a drop in visual acuity, the first patient was sent to the Institute for Eye Diseases, Clinical Centre of Serbia. The existence of the ciliary body tumour was suspected, so she underwent a UBM diagnostic procedure. UBM showed fibrin in the anterior chamber of the eye, occlusion of the pupil, and the absence of tumour. The second patient had a part of the chamber angle filled with solid lesion. UBM showed a solid tumour lesion filling the chamber angle in the lower part of the anterior chamber. The origin of the tumour was the ciliary body rather than the choroid which was shown by the B scan ultrasound. Lipodermoid was found by clinical examination of the third patient. He underwent UBM in order to exclude the involvement of the sclera under the lesion. UBM visualized a subconjunctival lesion lying on the sclera, reaching the limbus of the cornea. The difference in ultrasound reflection of the two tissues helped us to confirm that the sclera was not involved. Our fourth patient underwent an antiglaucomatous procedure, and the assessment of the chamber angle opening was the reason for the UBM examination. Parameters measured in the lower quadrants (6 o'clock) that we managed to obtain were the following: AOD (250 ?m) - 180 ?m, AOD (500 ?m) - 400 ?m, TIA - 34.39 deg., ARA - 0.25 mm2. Comparing them to normal values, we came to the conclusion that the chamber angle was open in the lower part of the anterior chamber. Conclusion. Ultrasound biomicroscopy gives us plenty of useful information when it comes to diagnosing the anterior chamber pathology.

Purpose: To report a case of a cyclodialysis cleft that was successfully managed with gas endotamponade and cyclocryotherapy. Methods: A 37-year-old male victim of a severe blunt ocular trauma was referred to our service for evaluation and treatment of a left eye hypotony. Clinical examination revealed an intraocular pressure of 2 mm Hg, a cyclodialysis cleft extending from the 11 to 1 o'clock positions and a hypotonic maculopathy. Left eye best corrected visual acuity (BCVA) was 3/10. The patient failed to respond to conservative treatment with atropine 1%, so a single bubble of 16% C2F6 was injected into the vitreous cavity, followed by superior quadrant transconjunctival cyclocryotherapy. Results: After gas absorption, the intraocular pressure increased to 11 mm Hg and became steady during the 24 months of follow-up. His hypotonic maculopathy resolved, and the BCVA improved to 9/10. Complete closure of the cyclodialysis cleft was documented with ultrasound biomicroscopy. Conclusion: Cryotherapy associated with gas endotamponade is a minimally invasive technique that could be considered for patients with cyclodialysis clefts that fail to respond to medical therapy.

Artemisinin derivatives are now the most potent and rapidly acting antimalarials. The aim of this study was to assess thein vivoefficacy and tolerability of a combination of Malartin (an artesunate) and sulphadoxine-pyrimethamine (SP) in the treatment of uncomplicated falciparum malaria in Dibanda, Cameroon. A total of 197 subjects were recruited into the study and administered Malartin for 3 days and SP as a single dose on day 0. Only 174 of the subjects were successfully followed up on days 3, 7, and 14. The overall success rate of the drug combination was 92.53%. Parasite density decreased during the follow-up period in different age groups, sexes, and social classes. The prevalence of anaemia decreased from 22.99% at enrolment to 9.77% on day 14, and the difference was significant (P<0.05) on all days of followup. The drug combination did not give rise to any serious side effects.

Specialized Structure

The ciliary body (CB) is part of the uvea and is a complex, highly specialized structure with multiple functions and significant relationships with nearby structures. Its functions include the aqueous humor (AH) production in the ciliary processes, the regulation of the AH output through the uveoscleral pathway, and accommodation, which depends on the ciliary muscle. Also, the CB is an important determinant of angle width as it forms part of the ciliary sulcus. Until recently, knowledge of the CB was based on histological studies. However, this structure can currently be assessed in vivo using imaging techniques such as ultrasound biomicroscopy (UBM) and optical coherence tomography (OCT). Both techniques have shown good reproducibility of their measurements allowing for quantification of CB dimensions and their localization. In effect, studies have shown a larger CB in myopia and its diminishing size with age. Swept-source OCT devices offer fast, non-invasive high-resolution imaging allowing the identification of multiple structures. UBM requires contact and is uncomfortable for the patient. However, this technique offers deeper imaging and therefore remains the gold standard for assessing the posterior chamber, ciliary processes, or zonula. The clinical utility of CB imaging includes its assessment in different types of glaucoma such as angle-closure, malignant or plateau iris. Diagnostic CB imaging is also invaluable for the assessment of ciliochoroidal detachment when suspected, the position after the implantation of a pre-crystalline or sulcus-sutured lenses, diagnosis or monitoring of cysts or tumors, sclerotomies after retinal surgery, intermediate uveitis, or accommodation.
