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.

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.

Introduction. The causes leading to dislocation of the natural lenses are different involving injuries, hereditary diseases and spontaneous dislocation. Spontaneous dislocation of a transparent natural lens is extremely rare, especially dislocation of the anterior eye chamber. We report a case of spontaneous dislocation of the transparent natural lens to the anterior eye chamber in a patient who had no history of eye injuries. Case Outline. The patient was a 17-year old boy. Lens dislocation was spontaneous, and the patient presented for ophthalmological consultation due to a sudden vision impairment of the left eye. Biomicroscopic examination verified that the transparent lens was in the anterior chamber, and it was spherophakia of lesser diameter; there were no signs of increased intraocular pressure, as typically expected in lens dislocation to the anterior chamber. The patient was operated on in general anaesthesia. Surgery involved intracapsular extraction of the dislocated lens through a corneoscleral incision. Conclusion. This case report shows that a spontaneous dislocation of the natural lens may occur in younger people. The dislocated spherophakic lens to the anterior eye chamber did not contribute to the rise of the intraocular pressure and development of acute glaucoma. The acute glaucoma resulted from the pilocarpine narrowing of the pupil due to pupillary block. The intracapsular instrumental extraction of the dislocated transparent lens from the anterior chamber was successfully completed through a corneoscleral incision.

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.

Introduction. There are various reasons for the lens dislocation. Spontaneous dislocation of a clear lens is extremely rare, especially its dislocation to the anterior chamber. Case Outline. The author presents a case of spontaneous clear lens dislocation to the anterior chamber in both eyes in a patient without the history of any trauma. Dislocation occurred spontaneously, first in the left eye, along with a sudden decrease of vision. The ophthalmologist found a clear lens in the anterior chamber, without any sign of an elevated intraocular pressure, as should have been expected. The dislocated lens was removed surgically (intracapsular extraction) with the preventive basal iridectomy. Two years later, the same happened in the right eye: clear lens moved spontaneously to the anterior chamber, with a decrease of vision, but again without any rise of intraocular pressure and/or any pain. Intracapsular extraction of the lens with basal iridectomy was done again. Conclusion. The presented case demonstrates that spontaneous dislocation of the transparent lens to the eye anterior chamber can occur in both eyes at different time intervals. We suggest the removal of dislocated lens in the anterior chamber by the intracapsular extraction.

We describe a case of Urrets-Zavalia syndrome (UZS) in a healthy 56-year-old woman who underwent femtosecond-assisted phacoemulsification with intraocular lens implantation in both eyes. One month after an uneventful postoperative course in the left eye, the right eye was operated. Dilated pupil which was nonreactive to light appeared on day 21 postoperatively. This was discovered upon examination following anterior chamber inflammatory reaction which occurred 2 weeks following her surgery. Our case report emphasizes the importance and danger in developing UZS even if the reaction in the anterior chamber does not occur immediately after surgery. In addition, the importance of intraocular pressure follow-up in the period after UZS is acknowledged.

A 49-year-old gentleman presented with a 1-day history of painful deterioration of vision in his right eye. He was lifting heavy weights just before this visual loss. On examination, his vision was perception of light in that eye, with a medically uncontrollable high intraocular pressure and hyphaema almost completely filling his anterior chamber. An ultrasound performed suggested a working diagnosis of a Valsalva related ‘eight ball’ bleed. After an anterior chamber washout, he had another episode of bleeding three days later. A pars plana vitrectomy was performed and the sample obtained was sent off to the laboratory, revealing a choroidal melanoma. Following enucleation, the histology confirmed a large necrotic spindle cell melanoma, with a haemorrhagic background. Fortunately, no liver metastasis was found. Since his diagnosis 3 years ago, he continues to be followed up in an artificial eye clinic and has regular liver scans under the care of his oncologist.

Purpose The aim of this study was to report the use of micropulse trans-scleral cyclophotocoagulation as an adjunct therapy for two cases of medically uncontrolled intraocular pressure spikes due to anterior segment inflammation. Case description: Case 1 had previous cataract surgery and exhibited an intraocular pressure spike due to phacoantigenic uveitis (right eye intraocular pressure = 52 mmHg). Despite medical treatment, the right eye intraocular pressure remained high (43 mmHg), thus micropulse trans-scleral cyclophotocoagulation was carried out as a rescue therapy. After micropulse trans-scleral cyclophotocoagulation, the intraocular pressure at 1 day and 3 weeks was 9 and 16 mmHg, respectively. Case 2 had a history of previous blunt ocular trauma and 180° of angle recession. Both eyes were pseudophakia and underwent right eye Nd:YAG laser capsulotomy for posterior capsular opacification. Immediately after the procedure, the right eye intraocular pressure increased to 64 mmHg. Due to poor response to medical therapy, rescue micropulse trans-scleral cyclophotocoagulation was performed. After micropulse trans-scleral cyclophotocoagulation, the intraocular pressure at 1 day and 2 months was 12 and 21 mmHg, respectively. Conclusion Micropulse trans-scleral cyclophotocoagulation successfully decreased intraocular pressure in both cases of acute rise in intraocular pressure. Micropulse trans-scleral cyclophotocoagulation can potentially be useful as a rescue procedure to safely reduce medically uncontrollable intraocular pressure spike due to anterior segment inflammation.

Purpose: To describe the feasibility and efficacy of performing single-pass four-throw pupilloplasty for secondary angle-closure glaucoma post silicon oil tamponade. Methods: The procedure was performed in five eyes of five patients. All the cases underwent silicon oil removal with single-pass four-throw pupilloplasty. Single-pass four-throw procedure involves a single pass of needle through the iris tissue that is to be apposed followed by taking four throws by passing the suture end through the loop that is withdrawn from the anterior chamber as in a modified Siepser’s slip-knot technique. Both the suture ends are pulled and this leads to sliding of the loop into the anterior chamber. Surgical pupilloplasty stretches the peripheral iris tissue and helps in breaking the peripheral anterior synechia. Intraoperative gonioscopy and anterior segment optical coherence tomography were performed in all the cases. Results: Intraoperative gonioscopy and anterior segment optical coherence tomography demonstrated opening of the anterior chamber angles with breakage of peripheral anterior synechia. The mean preoperative and postoperative best-corrected visual acuity in logarithm of minimum angle of resolution was 1.24 ± 0.23 and 0.56 ± 0.18, respectively (p < 0.001). The mean preoperative and postoperative intraocular pressure was 38.2 ± 4.97 and 13.0 ± 2.35 mm Hg, respectively. There was a significant decrease in intraocular pressure and marked improvement in visual acuity in all the cases. Conclusion: Surgical pupilloplasty helps to relieve the post-silicon oil-induced secondary angle-closure glaucoma by breaking peripheral anterior synechia and significantly opening the anterior chamber angles.

PurposeTo study the correlation between intraocular pressure (IOP) reduction and the number of hyper-reflective particles appearing in the anterior chamber following selective laser trabeculoplasty (SLT).Material and methodsIn this prospective interventional study, we included primary open-angle glaucoma patients. All participants received a standardised SLT session, which consisted of 100 pulses of 0.9 mJ over 360°. Anterior segment optical coherence tomography (4×4 mm volume scan, 101 horizontal cross-sectional scans) and applanation tonometry were performed before SLT and 15 min, 1 day, 1 week, 1 month and 3 months after. Particles were counted on cross-sectional scans using a standardised algorithm.ResultsIn this study, we included 25 patients (25 eyes), 14 males and 11 females, with a mean age of 68.9±10.5 and baseline IOP of 21.4±4.5 mm Hg. IOP at month 1 and month 3 after SLT was 18.0±4.0 and 17.4±3.3 mm Hg, respectively. The mean number of anterior chamber particles before and 15 min after SLT was 0.62±0.2 and 7.1±2.0 particles/mm2, respectively (p=0.036). There was a statistically significant correlation between the mean number of anterior chamber particles 15 min after SLT and IOP reduction at 1 month (r=0.62, p=0.03) and 3 months (r=0.71, p=0.01).ConclusionThe number of the anterior chamber particles graded using anterior segment optical coherence tomography after the procedure correlates with the IOP-lowering effect of SLT.

Abstract Purpose: In this study the acute effects of 1 session of hyperbaric oxygen therapy on eye anterior segment morphology and on intraocular pressure was evaluated.Materials and methods: 30 patients taking hyperbaric oxygen therapy for different indications were included in this prospective study. Only the right eye per patient was included in the study. The refractive errors were measured with autorefractometry, intraocular pressures were measured with pneumatic tonometry; anterior segment parameters pachymetry, keratometry, anterior chamber depth and iridocorneal angle values were measured with corneal topography prior to and 24 hours after 1 session of hyperbaric oxygen therapy.Results: In this study 30 eyes from a total of 30 patients were evaluated; 19 men (% 64) and 11 women (% 36). Median age was 44.33 ±16.12 (Age range 18-80 years). Mean intraocular pressure was 13.7 ±4,16 mmHg (milimetermercuries), mean central corneal thickness was 531.9 ±28.24 μm, mean anterior chamber depth was 3.30 ±0.375 mm, mean iridocorneal angle value was 35.3± 6.61 degrees before hyperbaric oxygen therapy. The mean intraocular pressure was 12.66±4,54 mmHg, mean central corneal thickness was 529.43± 26.68 μm, mean anterior chamber depth was 3.28±0.372 mm, mean iridocorneal angle value was 34.5±6.42 degrees after HBOT. A statistically significant decrease in these values were recorded. No statistically significant changes were found in spheric equivalent and keratometry values of the patients before and after HBOT.Conclusions: After one session of HBOT a decrease in intraocular pressure, central corneal thickness, anterior chamber depth and iridocorneal angles of patients were observed; keratometry and spheric equivalent values remained unchanged. More studies are needed in order to use the effects of HBOT on anterior segment morphology and on intraocular pressure for situations like glaucoma, corneal edema etc.
