Clinical History: A 2-year-old, female Poodle dog presented to the Emergency Service at the Veterinary Teaching Hospital (VTH), Louisiana State University School of Veterinary Medicine with a history of lethargy and anorexia. At clinical examination the dog was anemic and febrile. The dog was bilaterally blind. The right eye was buphthalmic and the intraocular pressure was elevated (42 mm Hg). During an ophthalmological consult, bilateral severe panuveitis and optic neuritis with secondary glaucoma in the right eye was diagnosed and treatment was instituted. Despite treatment, the intraocular pressure kept increasing (up to 72 mm Hg overnight), and the clinicians decided to enucleate the right eye due to poor prognosis. After one month, and no response to treatment, the left eye was also enucleated. Gross Findings: Right and left eyes: The vitreous chamber was filled with a yellow, gelatinous exudate while the anterior chamber was filled with a translucent, gelatinous fluid. The retina appeared detached and embedded within the exudate present in the vitreous chamber.

Intraocular lens (IOL) dislocation is a rare complication of cataract extraction requiring prompt surgery. This case report aims to raise awareness of such cases and the importance of post-surgery follow-up. A 58-year-old female patient was found with anterior IOL dislocation a week after phacoemulsification surgery in her right eye. Visual acuity of the right eye was 1/60 with ciliary injection and IOL dislocation to the anterior chamber of the right eye. The patient underwent surgery of the right eye and the IOL haptic was found to be broken. In this case report, the factors affecting IOL dislocation are axis length, broken IOL haptic, and patient activity that increased intraocular pressure. Cataract extraction surgery, although common, needs to be conducted carefully, and it is important for ophthalmologists and general practitioners to detect this condition, especially in rural areas where facilities are limited, as IOL dislocation could occur and requires immediate treatment to achieve a better result.

We report a rare case with histologically proven melanocytoma of the iris that demonstrated diffuse melanocytic proliferation with uncontrolled secondary glaucoma and investigate the etiology of the intraocular pressure elevation. The patient was a 78-year-old man with a history of darkened iris of his left eye. The intraocular pressure was 39 mm Hg. A slit-lamp examination showed a diffuse darkened iris, and a gonioscopic examination revealed open angle with circumferential heavy pigmentation. There was no pigment dispersion of the anterior chamber and no pigment deposition of the cornea. We suspected malignant ring melanoma in the left eye and enucleated it. The globe was examined with light and electron microscopy. Light microscopy revealed the presence of heavily pigmented tumor cells in the iris, ciliary body, trabecular meshwork, and Schlemm’s canal. A bleached preparation showed large tumor cells with central and paracentral nuclei without mitosis. Electron microscopy of the trabecular meshwork revealed melanin-bearing tumor cells invading the intertrabecular spaces, and the melanin granules were not phagocytosed in the trabecular cells. The mechanical obstruction of the aqueous flow by the tumor cells may be a major cause of secondary glaucoma in eyes with iris melanocytoma presenting diffuse proliferation.

Secondary glaucoma may develop after vitreoretinal surgery as it is a known risk factor for its development. When the risk factors are more than one, for instance along with neovascular glaucoma (NVG), the secondary glaucoma may become recalcitrant and very difficult to manage. Surgical intervention is often warranted to control intraocular pressure (IOP) and prevent progressive glaucomatous damage in patients with refractory glaucoma, and glaucoma drainage implant may be preferred as the primary choice. We describe a patient who develop secondary glaucoma after vitrectomy and silicone oil (SO) injection due to unresolved vitreous hemorrhage in proliferative diabetic retinopathy (PDR) and subsequent NVG. Baerveldt glaucoma implant (BGI) was carried out and placed in the superotemporal quadrant with longer anterior chamber tube placement to prevent escape of SO through the tube. Qualified success was achieved with additional one fixed-drug combination (FDC). However, 3 years later, the tube was blocked by the iris tissue at the inferior edge of the pupil. Tube trimming was performed efficiently using a simple technique. The distal end of the tube was pulled out of the anterior chamber through a paracentesis just next to the tube entrance and trimmed to the appropriate length. More than a year after the surgery, IOP was still well controlled with the same FDC. Unfortunately, the visual acuity could not be recovered due to advanced PDR.

Records of 48 dogs (57 eyes) that underwent intracapsular lens extraction (ICLE) of displaced lenses were reviewed. Preoperatively, 73% (19/26 eyes) of eyes with anterior luxations had secondary glaucoma compared to 43% (10/23 eyes) with subluxations and 38% (3/8 eyes) with posterior luxations. Forty-one of 57 eyes (72%) had vision and intraocular pressure (IOP) less than 30 mm Hg four to six weeks after surgery. This percentage declined to 61% (22/36 eyes) in three months and 53% (8/15 eyes) in 12 months. Eyes with glaucoma before ICLE had a lower success rate (66%) than eyes without (82%). Since secondary glaucoma was the most common cause of failure, this study suggests that removal of a subluxated lens or a posteriorly luxated lens should be recommended before the lens moves into the anterior chamber.

We assessed the outcomes of the use of anterior chamber foldable lens for unilateral aphakia correction at the University Teaching Hospital of Yaounde. In this retrospective, non-comparative, consecutive case series study, we reviewed the records of patients who underwent an operation for aphakia correction by the means of injection of an angular supported foldable lens between January 2009 and December 2011 in the University Teaching Hospital Yaounde. Student's paired t-test was carried out to compare preoperative and postoperative visual acuity (VA) and intraocular pressure (TOP). P-values less than 0.05 were considered statistically significant. Twenty-one patients were included in the study; twelve were male (57.1%) and nine were female (42.9%). The mean age was 55.38 ± 17.67 years (range 9–75 years). The mean follow-up duration was 5.95 ± 3.14 months (range 2–12 months). The mean logMAR visual acuity was 1.26 ± 0.46 pre-operatively and 0.78 ± 0.57 post-operatively ( P = 0.003). The change in intraocular pressure was not statistically significant. Complications included intraocular hypertension (over 21 mmHg) in 3 patients (14.3%) and macular edema, pupillar ovalization, and retinal detachment in one patient each. The results indicate that injection of an angular support foldable lens in the anterior chamber is a useful technique for the correction of aphakia in eyes without capsular support. More extended follow-up, however, and a larger series of patients are needed to ascertain the effectiveness and safety of this procedure.

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.

Secondary angle closure in a pseudophakic eye due to pupillary block, more than a decade following phacoemulsification, has not been reported. We managed a 75-year-old female presenting with sudden, painful diminution of vision and raised intraocular pressure in the right eye. The key finding was an almost flat anterior chamber with intraocular lens in normal position clinically as well as on ultrasound biomicroscopy. The posterior chamber was ballooned up by vitreous, which was cleared surgically to restore the anatomy. Meticulous clinical examination augmented by ultrasound biomicroscopy findings helped us to diagnose and manage this case for satisfactory intraocular pressure and visual outcome.

Background: Management of secondary glaucoma in nanophthalmos has always been challenging, especially for patients with extremely short axial length and extensive angle synechia. This case report discusses a nanophthalmic patient with secondary glaucoma and extensive angle synechia. Case presentation: A 60-year-old woman was referred to our hospital with uncontrolled intraocular pressure (IOP) in her left eye (LE). Slitlamp examination revealed small cornea and shallow anterior chamber (AC) in both eyes. Extensive angle synechia was seen on gonioscopy, and the IOP and axial length were 36 mmHg/15.79 mm in the left eye. She was diagnosed with nanophthalmos and secondary angle-closure glaucoma LE. Laser peripheral iridectomy (LPI) was performed, but the IOP LE remained elevated and uncontrolled on brinzolamide and brimonidine. The IOP LE was then normalized with the application of 2% pilocarpine. During the follow-up period, the AC of the LE showed progressive shallowing, and 5 months post LPI the IOP became uncontrollable. Goniosynechialysis combined with phacoemulsification, lamellar sclerectomy, sclerostomy, peripheral iridectomy, capsulotomy, and anterior vitrectomy were performed LE. Immediately after surgery, the AC deepened and the IOP stabilized. However, the IOP rose again post-surgically at 1 week and again at 2 months. A generally shallow AC and obstructed capsule hole were present. YAG laser capsulotomy was performed, and the IOP normalized and the AC deepened. Eighteen months after surgery, the IOP LE was 12 mmHg and the AC remained stable. Conclusion: Goniosynechialysis combined with multiple surgical procedures could be considered an alternative treatment regimen for nanophthalmos patients with secondary glaucoma and extensive angle synechia.

A 7-y-old Black Russian Terrier dog was evaluated for chronic lameness of the right forelimb and concurrent weight loss. Clinical examination revealed a pigmented mass arising from digit 4 of the right forelimb; the digit was amputated and submitted for histologic evaluation. Histologically, the neoplasm was composed of ill-defined streams, sheets, and clusters of melanocytes admixed with a distinct population of malignant epithelial cells forming glands and nests. The diagnosis was a biphasic malignant melanoma adenocarcinoma, a rarely reported neoplasm in human medicine that has not been described in veterinary medicine, to our knowledge.

Abstract Background We report a case of uveitis–glaucoma–hyphema (UGH) syndrome in a highly myopic pseudophakic eye with seemingly normal positioning of a two-haptic intraocular lens (IOL). Case presentation The patient was a 61-year-old woman suffering recurrent episodes of blurred vision, floaters, redness, elevated intraocular pressure (IOP), and pain in the right eye following implantation of a sclera-fixed IOL. The symptoms were alleviated by the systemic and topical administration of IOP-lowering and anti-inflammatory medications. A slit-lamp examination revealed depigmentation and atrophy of the iris, and a quiet anterior chamber in the right eye. Endophthalmitis caused by hypovirulent bacteria and UGH syndrome were both considered. Ultrasound biomicroscopy (UBM) and gonioscopy provided direct evidence of malpositioned IOL haptics, which pushed the root of the iris forward, resulting in persistent mechanical chaffing, the probable cause of UGH syndrome. IOL explantation resolved her symptoms. Negative bacterial culture results for the IOL excluded the possibility of endophthalmitis. Conclusions Heightened awareness of underlying UGH syndrome and prompt UBM are important when doctors encounter a patient with a sclera-fixed IOL suffering from recurrent anterior segment inflammation and elevated IOP.
