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.

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.

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.

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.

Elevated intraocular pressure (IOP) is the most important risk factor associated with the progression of glaucoma and the research on animal models is constantly evolving. Rebound tonometry has been shown to be useful for the evaluation of IOP, not only for the human patient but also for the animal patient. The aim of the paper is to assess intraocular pressure in guinea pigs in order to establish reference values. IOP was measured for three days, at different time intervals, in 40 guinea pigs, using the iCare Tonovet TV01 tonometer. The mean values obtained in coloured guinea pigs were 13.82 mmHg ± 1.64 mmHg in the right eye, 14.11 mmHg ± 1.68 mmHg in the left eye, and in white guinea pigs 12.56 mmHg ± 0.95 mmHg in the right eye, 13.02 mmHg ± 1.29 mmHg for the left eye. The values obtained from this study it can be concluded that the strain of coloured, records the highest values in the morning, which remain linear during the day, and decrease in the evening compared to the white strain which has a constant evolution during the day, and in the evening increases.

A case of a two-year-old male Pinscher with a history of discomfort in the right eye was reported. The left eye had been enucleated by the referring veterinarian due to the same symptom with unsuccessful clinical treatment. The Schirmer tear test value was elevated and a decreased intraocular pressure was observed by applanation tonometry. Biomicroscopy revealed profuse corneal edema and keratoconus and fluorescein staining was negative. Gonioscopy and ophthalmoscopy did not provide any relevant data due to the corneal alterations. Bullous keratopathy was diagnosed. Surgery was performed in two steps: 1) superficial keratectomy and 360º conjunctival flap, and 2) superficial keratectomy to restore corneal transparency. Thirty days after the second superficial keratectomy, the third eyelid flap was removed. Conjunctivalization of the upper nasal quadrant of the cornea was observed. The axial portion of the cornea was transparent and vision was restored.

Retinopathy of prematurity (ROP) is a leading cause of childhood blindness that occurs due to incomplete development of retinal blood vessels in preterm infants. Glaucoma is an ocular comorbidity in some patients with ROP, and it may be associated with immature anterior chamber development, ROP itself, or the treatment for ROP. There have been a few reports of narrow-angle glaucoma after laser treatment for ROP. In this case report, we describe the course of a female infant born at 24 weeks and 5 days of gestational age with treatment-requiring ROP treated with laser photocoagulation who subsequently developed very elevated intraocular pressure and shallow anterior chambers without pupillary block. The patient required bilateral ab externo trabeculotomy for elevated intraocular pressure, which normalized after the procedure. The patient has remained stable at the last follow-up at 51 weeks postmenstrual age. Differing from previous glaucoma presentations in this setting, we illustrate a case of elevated intraocular pressure and anterior chamber narrowing after laser therapy without pupillary block or synechiae. The possible multifactorial etiology of glaucoma in this patient, including incomplete angle development, ischemia, and laser treatment, highlight the need for glaucoma screening in patients with ROP, both in the short and long term.

Popliteal artery thrombosis may present as a complication of an osteochondroma located in the vicinity of the knee joint. This is a case report of a 26-year-old man with symptoms of the right lower extremity ischaemia without a previous history of vascular disease or trauma. Plain radiography, magnetic resonance angiography and Doppler ultrasonography documented the presence of an osteochondrous structure of the proximal tibial metaphysis, which displaced and compressed the popliteal artery, causing its occlusion due to intraluminal thrombosis..The patient was operated and histopathological examination confirmed the diagnosis of osteochondroma.

A case report on a 49-year-old female with diagnoses of ocular hypertension in her left eye (LE) treated with 250 mg/day acetazolamide for 2 years. During the slit-lamp examination, complete occlusion of both iridocorneal angles was detected. Intraocular pressure (IOP) was 10 and 35 mmHg in the right eye and LE, respectively. Phacotrabeculectomy was performed in the LE. After 1 month of the procedure, the patient developed a slowly progressive miopization from −1 to −3 diopters (D) the following months. Approximately 3 months after surgery, the patient developed an episode of acute pain, athalamia, and IOP 45 mmHg in her LE. Late-onset malignant glaucoma was suspected and the patient was treated with topical hypotensive and cycloplegic agent until a prompt vitrectomy was performed. Deepening of the anterior chamber and restoration of IOP to normal range was obtained after surgery.

AbstractThe purpose of this study was to report the incidence of elevated intraocular pressure (IOP) after intravitreal injection (IVI) of anti-vascular endothelial growth factor (VEGF) in Japanese patients with age-related macular degeneration (AMD). A retrospective study of chart review of patients who underwent ≥ 10 intravitreal anti-VEGF injections between April 2009 and December 2019 was conducted. Elevated IOP was defined as IOP ≥ 25 mmHg at one visit. Cases with elevated IOP resulting from IVI were identified. Furthermore, the association between elevated IOP and some parameters, as the risk factors that influence elevated IOP, was investigated. A total of 402 eyes of 370 patients were included in this study. Twenty-eight eyes of 26 patients (7.0%) were identified as cases with elevated IOP after IVI. The mean time of elevation after baseline was 50.6 ± 26.5 months. History of glaucoma (p = 0.021; odds ratio, 5.85), treatment modality (p = 0.019; odds ratio, 6.32), and total number of injections (p = 0.003; odds ratio, 1.03) were significantly associated with elevated IOP. A late complication of elevated IOP is associated with IVI in patients with AMD. Particularly, history of glaucoma and treat and extend regimen with frequent injections were found to be risk factors of elevated IOP.

A patient presented with complaints of a sudden decrease in vision, ocular redness, and pain in the right eye. The patient had a history of clear lens extraction with intraocular lens (IOL) implantation for myopia 2 years previously. He had been prescribed topical steroids for episodes of inflammation that occurred repeatedly every 1–2 months. With a presumptive diagnosis of chronic endophthalmitis, a 23-G transconjunctival sutureless pars plana vitrectomy (PPV) with delivery of intravitreal antibiotics was performed the next day. Culture sensitivity testing of the vitreous sample indicated <i>Pseudomonas stutzeri</i> that was sensitive to ceftazidime and gentamicin. Two weeks later, the patient presented with sudden loss of vision and all the signs of recurrent endophthalmitis. 23-G transconjunctival sutureless PPV was performed along with removal of the posterior chamber IOL through a corneal incision. Complete resolution was only achieved after removal of the IOL, resulting in excellent visual recovery. Due to its chronic and fulminating nature, <i>P. stutzeri</i> can induce endophthalmitis and should be considered in the differential diagnosis. Aseptic measures are the best prevention.
