Purpose: To present a relatively uncommon case with a secondary iris cyst in the anterior chamber and its successful management with an anterior chamber mass excision surgery. Case report: A 46-year-old Chinese woman presented with a dark shadow in her left eye for 6 months without any other discomfort. She had a history of blunt ocular trauma by a badminton strike 3 years ago. Slit-lamp examination showed a small, nearly circular, sharply demarcated, and movable mass in the anterior chamber OS, which could change its position with head tilt. The anterior segment optical coherence tomography revealed a well-circumscribed cystic lesion in the anterior chamber with higher reflective outer layer and lower internal reflectivity. An anterior chamber mass removal surgery was performed without recurrence up to 1 year. Conclusion: Secondary free-floating iris cyst following a blunt trauma is rarely reported. It is relatively stable and nonprogressive so it may remain asymptomatic for a long time. Appropriate imaging techniques are necessary for facilitating diagnosis and therapy. Therapeutic management should be considered if visual symptoms arise, especially when complications occur.

BACKGROUND: Ocular trauma may alter the anterior segment condition that may lead to secondary glaucomas such as inflammation, hyphema, angle recession, and lens subluxation. One of the most common procedures to decrease intraocular pressure (IOP) is trabeculectomy by creating pathways that allow aqueous humor to flow out of the anterior chamber. Scleral tissue destruction can cause damage in thin areas (such as posterior to the rectus muscle insertions) as in case of scleritis. CASE REPORT: An 11-year-old boy presented to the Ophthalmology Department of Universitas Sumatera Utara Hospital with a bigger white grayish mass and blurry vision. There was a history of the left ocular trauma 6 years ago, followed by redness of the eye, but not treated properly. On the general examination, the patient’s left eyes looked cloudy. On ocular examination, the left eye visual acuity was 1/300 and IOP was 28 mmHg. Segment anterior examination showed staphyloma from 9 to 12 o’clock, conjunctival injection, corneal scar, shallow anterior chamber, and cloudy lens. We could not asses the posterior segment due to cloudy media. We gave anti-glaucoma medication for 1 month, but the IOP did not decrease. We performed a trabeculectomy to control IOP and to prevent staphyloma from getting bigger. CONCLUSION: Trabeculectomy was an effective procedure to control IOP in a staphyloma eye following ocular trauma.

Chamber Angle

Assessment of the anterior chamber angle (ACA) is an essential part of the ophthalmological examination. It is intrinsically related to the diagnosis and treatment of glaucoma and has a role in its prevention. Although slit-lamp gonioscopy is considered the gold-standard technique for ACA evaluation, its poor reproducibility and the long learning curve are well-known shortcomings. Several new imaging techniques for angle evaluation have been developed in the recent years. However, whether these instruments may replace or not gonioscopy in everyday clinical practice remains unclear. This review summarizes the last findings in ACA evaluation, focusing on new instruments and their application to the clinical practice. Special attention will be given to the comparison between these new techniques and traditional slit-lamp gonioscopy. Whereas ultrasound biomicroscopy and anterior segment optical coherence tomography provide quantitative measurements of the anterior segment’s structures, new gonio-photographic systems allow for a qualitative assessment of angle findings, similarly to gonioscopy. Recently developed deep learning algorithms provide an automated classification of angle images, aiding physicians in taking faster and more efficient decisions. Despite new imaging techniques made analysis of the ACA more objective and practical, the ideal method for ACA evaluation has still to be determined.

Ciliary body medulloepitheliomas in childhood often masquerade other intraocular conditions due to its insidious nature as well as its secondary effects on proximal intraocular tissues in the anterior chamber. We report a case where a ciliary body medulloepithelioma in a two-year-old boy presents with chronic uveitis, cataract, and an uncontrolled secondary glaucoma after an innocuous blunt ocular trauma. The diagnosis was only made after the occurrence of a ciliary body mass. We discuss the clinical features of ciliary body medulloepitheliomas, the implications of a delayed diagnosis and treatment as well as the concern of periorbital tumor seeding with the use of an aqueous shunt implant in this case.

Background. The vitreous body is an important part of the ocular body fluid. A foldable capsular vitreous body (FCVB) is designed to treat chronic adverse complications in severe ocular trauma and silicone oil-dependent eyes. This study is aimed at investigating a method for implanting an FCVB, its postoperative efficacy, and clinical value. Methods. A retrospective analysis was performed on data from 18 patients who underwent vitrectomy and FCVB implantation for severe ocular trauma and silicone oil-dependent eyes between March 2019 and May 2020. All treated eyes underwent clinical examinations involving the best-corrected visual acuity, intraocular pressure, FCVB position, anterior segment photography, and wide-angle fundus photography regularly after surgery. Results. Eighteen eyes from 18 patients were enrolled in this study. A total of 2.00–4.20 ( 3.46 ± 0.78 ) ml of silicone oil were injected into the FCVB during surgery. The patients were followed up at 1, 2, and 4 weeks and 3, 6, and 12 months after surgery. Twelve months after surgery, visual acuity improved in 7 (38.89%) eyes. In contrast, 10 (55.56%) eyes showed no obvious improvement, and 1 (5.56%) eye had decreased vision. Intraocular pressure at 12 months was 10.13 ± 3.52  mmHg, which was comparable to that before the surgery ( t = 0.38 , P = 0.71 ). The anterior chamber depth examined by slit lamp was 2.00–3.00 cornea thickness (CT) in 7 eyes, 1.00–2.00 CT in 2 eyes, and <1.00 CT in one eye. The anterior chamber disappeared in eight eyes. There were eight eyes with clear cornea, four eyes with localized opacity, and two eyes with obvious gray-white opacity. There was no case of severe FCVB deflection, rupture, or exposure during the observation period. Conclusion. FCVB implantation is an effective and safe treatment for eyes with severe ocular trauma and silicone oil-dependent eyes. It may support retinal reattachment, slow down eyeball atrophy, reduce the risk of chronic adverse complications such as corneal endothelial decompensation, and maintain intraocular pressure and preoperative visual function.

Backgropund: Filtering bleb formation after surgical repair of penetrating globe injury is a rare occurrence. Case: A 45-year-old male who had undergone surgical repair of a corneoscleral laceration 16 months earlier presented to emergency room after blunt trauma to the left eye. His best-corrected visual acuities were 20/20 in the right eye and 20/25 in the left. An anterior segment examination found a conjunctival filtering bleb formation on scarred sclera at superotemporal location near the limbus. Anterior chamber was slightly shallow and the Seidel test was negative. Intraocular pressures were 17 mm Hg in the right eye, 7 mm Hg in the left. The fundus examination revealed no abnormal findings. The patient was treated with topical aplication of a steroid and a cycloplegic drop during three weeks. After 16 months follow-up, the visual acuity remained unchanged with the persistence of filtering bleb. IOP was 8 mm Hg in the left eye. Follow-up examinations showed no complications related to trauma. Conclusion: Blunt ocular trauma can cause dehiscence in old scleral scars and subsequent filtering bleb formation.

There is currently no objective portable screening modality for narrow angles in the community. In this prospective, single-centre image validation study, we used machine learning on slit lamp images taken with a portable smartphone device (MIDAS) to predict the central anterior chamber depth (ACD) of phakic patients with undilated pupils. Patients 60 years or older with no history of laser or intraocular surgery were recruited. Slit lamp images were taken with MIDAS, followed by anterior segment optical coherence tomography (ASOCT; Casia SS-1000, Tomey, Nagoya, Japan). After manual annotation of the anatomical landmarks of the slit lamp photos, machine learning was applied after image processing and feature extraction to predict the ACD. These values were then compared with those acquired from the ASOCT. Sixty-six eyes (right = 39, 59.1%) were included for analysis. The predicted ACD values formed a strong positive correlation with the measured ACD values from ASOCT (R2 = 0.91 for training data and R2 = 0.73 for test data). This study suggests the possibility of estimating central ACD using slit lamp images taken from portable devices.

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.

Background: We report a case of an occult retained intraocular foreign body detected four years after “forgotten” trauma. Case: A 23-year-old male presented with exodeviation and was referred as a case of epiretinal membrane. The anterior segment and adnexa were normal. Fundus examination revealed macular epiretinal membrane. An occult foreign body was localized in the retinal periphery. Imaging confirmed the diagnosis. Observation: Squint and epiretinal membrane may develop in cases of occult foreign bodies and may be the presenting sign years after trauma. Conclusion : A careful history of ocular trauma and thorough examination, complemented by radio imaging when needed, should be done in atypical cases.
