Abstract Background Tears in Schwartz-Matsuo syndrome are generally confirmed by preoperative ophthalmoscopic examination. A case of Schwartz-Matsuo syndrome with a tear detected by ultrasound biomicroscopy (UBM) and treated by UBM-guided scleral buckling was reported, and its mechanism was analysed. Case presentation A 40-year-old Chinese man presented with blurry vision and intermittent eye pain in his left eye for three days. The visual acuity of the left eye decreased from 20/20 to 20/40, and the intraocular pressure (IOP) fluctuated dramatically from 24.0 mmHg to 56.7 mmHg at the first visit. Gonioscopy revealed that the chamber angle remained open. A macula-involving inferior retinal detachment extending from 4:30 to 9:30 with no obvious causative break was observed through ophthalmoscopic examination. However, a single small tear was detected at the nonpigmented epithelium of pars plana of the ciliary body at approximately 7–8 o’clock by UBM. The loss of photoreceptor outer segments and ellipsoid zone and the existence of macular microcysts in the inner and outer nuclear layers were observed in the detached macula by optical coherence tomography. Then, he underwent successful scleral buckling guided by UBM. Three months later, the retina was flat with normal IOP, and the best corrected visual acuity of his left eye gradually improved to 20/25. UBM confirmed the closure of the tear. Conclusions Tear of the nonpigmented epithelium of the ciliary body is a rare condition associated with Schwartz-Matsuo syndrome. UBM plays a key role in detecting occult tears of the nonpigmented epithelium of the ciliary body, guiding scleral buckling surgery, and observing the closure of the tear postoperatively.

Abstract Background To report undescribed characteristics of patients with bilateral diffuse uveal melanocytic proliferation (BDUMP) on ultrasound biomicroscopy (UBM) and high-frequency B-scan ultrasonography. Case presentation Two of four participants presented with worsening bilateral vision after previously diagnosed primary pulmonary or ovarian carcinoma. The other two patients were diagnosed with lung carcinoma after presentation with BDUMP. All patients had ciliary body nevi-like lesion in combination with iris or ciliary body cysts, and uveal thickening on UBM. Focally elevated choroidal nevi-like lesion and exudative retinal detachment with choroidal thickening were detected with B-scan ultrasonography. Conclusions Our case series demonstrates the uveal characteristics of patients with BDUMP based on high-frequency B-scan ultrasonography and UBM. Ultrasonographic findings are crucial in the diagnosis of BDUMP because it is occult in nature.

A 32-year-old man presented with bilateral diminution of vision for 10 years. Visual acuity was light perception in both eyes with inaccurate projection in the oculus dextrus(OD) and accurate projection in the in oculus sinister (OS). Intraocular pressure was 6 and 12 mm Hg in the OD and OS, respectively. Slit-lamp examination revealed the presence of leucomatous corneal opacification with microcornea in oculus uterque (OU). Both eyes had a dislocated nucleus in the vitreous cavity on ultrasound B-scan with advanced cupping in the right eye. Ultrasound biomicroscopy revealed ciliary body atrophy in the OD and preserved ciliary processes (two quadrants) in the OS. In view of a partially preserved ciliary body function and a potential for gaining useful vision, we planned surgical intervention in the left eye. Deep anterior lamellar keratoplasty with pars planavitrectomy (PPV) and phacofragmentation of the nucleus was done. Donor lamellar graft was sutured after completion of PPV and nucleus fragmentation. The patient regained useful ambulatory vision postoperatively with clear corneal graft.

Introduction: Rhegmatogenous retinal detachment (RRD) is a potentially blinding condition. Objective: To evaluate the anatomical and functional outcome of surgery of RRD. Materials and methods: A prospective study of interventional case series was designed including 50 consecutive patients with RRD in a tertiary level eye center in Kathmandu. The patients underwent scleral buckling (SB) or pars plana vitrectomy (PPV) according to the proliferative vitreo-retinopathy (PVR) changes. All the patients had at least 3 months of follow-up. The anatomical and physiological outcome measures were primary retinal reattachment and improvement in visual acuity respectively. The surgery was considered successful when there was attachment of retina after the first surgery. Results: The mean age of these patients at the time of presentation was 46.24 ± 19.82 years. Of 50, sixty-six percent of the patients underwent SB and 34 % underwent PPV. Primary surgical success rate was 88 %. While comparing the initial best corrected visual acuity (BCVA) with the final, 72% had an improvement, 12 % unchanged and 16 % had a deteriorated visual acuity. Conclusion: The visual acuity improves and the anatomical success rate is high in the majority of the patients after surgery for rhegmatogenous retinal detachment.

We report a case of cyclodialysis with decreased visual acuity after microhook trabeculotomy (mTLO) successfully treated by vitreous surgery. A 41-year-old man had been medically treated for primary open-angle glaucoma in both eyes. He was scheduled to undergo mTLO due to progression of visual field impairment and unstable intraocular pressure in his right eye. His preoperative best-corrected visual acuity (BCVA) was 0.4 OD, and the intraocular pressure was unstable, ranging from 12 to 27 mm Hg. On the day after the operation, a shallow anterior chamber developed, and a low intraocular pressure occurred. His visual acuity continued to decrease, and cyclodialysis was confirmed by ultrasonic biomicroscopy. No improvement was obtained with medical treatment, and his BCVA dropped to 0.08 OD, while his intraocular pressure remained at 2–3 mm Hg. Three months later, a second surgery was performed by combining cataract surgery with intraocular lens implantation, vitrectomy, cryopexy for the pars plana of the ciliary body, and 20% SF6 gas tamponade. Two weeks after the reoperation, the intraocular pressure had been normalized to 12 mm Hg, and the BCVA had returned to 0.3. We successfully treated cyclodialysis as a complication after mTLO by vitreous surgery that led to the recovery of the visual acuity and intraocular pressure.

Abstract Background With the continuous improvement of surgical instruments in vitrectomy, the use of a trocar and cannula not only optimizes the incision process but also facilitates insertion and withdrawal of instruments during the procedure. Nevertheless, incision-related complications have also been reported in the literature. However, cannula fractures during 25G+ minimally invasive vitrectomy have rarely been reported. Case presentation A 62-year-old man underwent 25G+ pars plana vitrectomy for proliferative diabetic retinopathy. At the beginning of the operation, we used a trocar with a cannula to perform the sclerotomy. After the trocar was pulled out, the cannula was not seen on the surface of the sclera. Thus the inside and outside of the eye were carefully searched. The broken cannula tip was found in the ciliary body corresponding to the superonasal sclerotomy site and was subsequently removed. Conclusions Awareness regarding the risk of intraoperative fractures of 25G+ minimally invasive ocular surgical instruments is imperative. Whenever a broken or missing cannula is encountered, the residual part should be immediately extracted to avoid revision surgeries and postoperative complications.

Objective To investigate the clinical indications of ultrasound biomicroscopy (UBM) and anterior segment optical coherence tomography (AS-OCT) in eyes with inflammatory glaucoma. Methods Sixteen patients (16 eyes) with inflammatory glaucoma were analysed retrospectively. All of the subjects underwent UBM and AS-OCT scans, measuring the following parameters: central corneal thickness (CCT), central anterior chamber depth (ACD), angle-opening distance (AOD500), and trabecular-iris angle (TIA500) in four quadrants. Results Both the UBM and AS-OCT generated detailed, high-resolution images of the anterior segments of the eyes with inflammatory glaucoma. Moreover, the UBM and AS-OCT exhibited statistically similar measurement results for all of the indices. A Bland–Altman analysis showed a high level of agreement between the two imaging techniques. Additionally, the UBM was able to visualize the ciliary body and pars plana, while the cells and the flare in the anterior chamber appeared more pronounced in the UBM images. Conclusions Both the UBM and AS-OCT are useful tools for anterior segment imaging and taking measurements needed for evaluating inflammatory glaucoma. The AS-OCT has the advantages of being noninvasive and fast, whereas the UBM is presently unparalleled in the visualization of the ciliary body and pars plana.

PurposeTo describe the ocular clinical features, histopathological findings, and treatment outcomes of lymphomas involving the ciliary body.MethodsWe demonstrate three cases of ciliary body involvement by lymphoma from 2013 to 2019 in Peking Union Medical College Hospital (PUMCH). All patients underwent examinations including best corrected visual acuity (BCVA), slit-lamp microscopy, indirect ophthalmoscope, ultrasound biomicroscopy (UBM), and diagnostic vitrectomy. In addition, cytopathology, immunohistochemistry, gene rearrangement, cytometric immunophenotypic, or in-situ hybridization were used for determining the pathological type of lymphoma.ResultsThe patients were a 25-year-old man, a 52-year-old woman, and a 54-year-old man. Two patients had unilateral involvement, and one patient had bilateral involvement. All patients presented with anterior uveitis and elevated intraocular pressure. Ciliary body masses or infiltration were found in 3 patients. Two patients had diffuse large B-cell lymphoma and one patient had natural killer/T-cell lymphoma. All patients received 0.4 mg methotrexate intravitreal injections, and the ciliary body lesions regressed completely.ConclusionLymphomatous involvement of the ciliary body usually presents as an atypical anterior chamber reaction. Vitreous biopsy should be considered in these patients for diagnosis. Methotrexate intravitreal injection combine with chemotherapy or radiotherapy, might extend the survival time and preserve visual acuity for patients with ciliary body involvement by lymphoma.

Background. Differential diagnosis and follow-up of small anterior segment tumors constitute a particular challenge because they determine further treatment procedures. The aim of this study was to evaluate the efficacy of the UBM (ultrasound biomicroscopy) and AS-OCT (anterior segment optical coherent tomography) in distinguishing different types of anterior segment lesions. Methods. It was a retrospective, noncomparative study of case series of 89 patients with the suspicion of anterior segment tumor referred to the Ophthalmology Clinic, Medical University of Białystok, Poland, between 2016 and 2020. UBM was used to assess tumor morphology including height, location, and internal and external features. In cases in which UBM did not provide enough data, the AS-OCT images were analyzed. The data on demographics, best corrected visual acuity (BCVA), intraocular pressure (IOP), and rate of complications were also collected. Patients were followed up from 1 to 48 months. Results. The mean observation period was 26.61 ± 16.13 months. Among the patients, there were 62 women and 27 men at a mean age of 55.59 ± 19.48 (range: from 20 to 89 years.) The types of tumors were cysts (41%), solid iris tumors (37.1%), ciliary body tumors (7.9%), peripheral anterior synechiae (PAS 3.4%), corneal tumors (4.5%), and others (5.6%). Patients with cysts were younger than patients with solid iris tumor (p=0.002). Women had a cyst as well as solid iris tumor more frequently than men, but less often a ciliary body tumor (p<0.05). The horizontal size of tumor was positively correlated with patients’ age (rs = 0.38 and p=0.003) and negatively correlated with visual acuity (rs = −0.42 and p=0.014). During the 4 years of diagnosis, only 2.2% of lesions exhibited growth (growth rate of 0.02 mm per year). Among 15 cases in which visualization with UBM was not satisfactory (mostly iris nevi), AS-OCT was helpful in diagnosis of 13 patients. Conclusions. Both UBM and AS-OCT are effective methods in detection and diagnosis of tumors of the anterior eye segment, but in some cases, AS-OCT adds additional value to the diagnosis. Many lesions can be managed conservatively because they did not demonstrate growth during 4 years of the follow-up period.

Abstract Background: Choriodal osteoma is a rare condition. Although anti-VEGF treatment has been reported to be effective in managing choroidal neovascularisation secondary to choriodal osteoma, to the best of our knowledge, this report is the first report of using conbercept in such condition. Case presentation: This report describes a case of choroidal neovascularisation secondary to choriodal osteoma. A 37-year old female presented with decreased vision and distortion in left eye. Fundus image revealed an orange-yellow lesion with clear boundary in the macular area. Fluorescein angiography indicated choroidal neovascularization(CNV). OCT, B-scan and CT scan showed features of choroidal osteoma. Intravitreal Conbercept was given for four times over a period of 10 months, resulting stability of visual acuity and regression of CNV. Conclusions: Intravitreal Conbercept is effective in controlling choroidal neovascularisation secondary to choriodal osteoma.
