Effective Use

Purpose: Iris vascular tufts (IVT) are rare biomicroscopic capillary outgrowths from the pupillary margins. Patients are usually asymptomatic until presenting with blurred vision due to spontaneous hyphema or with raised intraocular pressure. Case report: A 61-year-old woman presented to eye casualty with left eye (LE) blurred vision and discomfort for 1 day. Her external ocular examination was unremarkable and visual acuity was 6/6 in the right eye (RE) and 6/9 in the LE. Biomicroscopic examination revealed a 2-mm hyphema in her LE and bilateral multiple small IVT and active bleeding from IVT at the pupillary margin of the LE at the 5 o’clock position. Diagnosis of LE active bleeding from IVT was made and she underwent argon laser photocoagulation directed at the source of bleeding. The bleeding stopped immediately after the second burn. She was followed up for 3 months; her visual acuity was 6/5 and 6/6 in the RE and LE, respectively, with no further problems. Conclusions: Iris vascular tufts are benign and recurrent hemorrhages are unlikely. Therefore, definitive argon laser photocoagulation or surgical treatment are reserved to arrest further episodes of hyphema. Our case demonstrates the effective use of argon laser photocoagulation to completely arrest active bleeding from IVT and excellent recovery of hyphema with no further problems for 5 years.

Background and Objectives: This case report discusses possible causes of chorioretinal fold (CRF) formation. Materials and Methods: A case report. Results: A 48-year-old man presented with a history of high myopia and primary open-angle glaucoma in both eyes. He underwent a trabeculectomy followed by phacoemulsification in both eyes. Two months later, he complained of blurred vision in the right eye. The intraocular pressure (IOP) was 17 mmHg in the left eye and 9 mmHg in the right eye. Refraction showed a hyperopic shift in both eyes. Slit-lamp examination showed a deep anterior chamber without cells and a well-functional bleb without leakage. Fundus examination revealed CRFs in the macula of the right eye. No papilledema, choroidal lesions, or other retinal lesions were found. Wrinkling of CRFs at the macula, an increase in central foveal thickness, and a fluid cleft were demonstrated by spectral-domain optical coherence tomography. After using steroid eye drops, the IOP in the right eye and refraction in both eyes recovered to the baseline level. Visual acuity improved in both eyes. Conclusions: CRFs in trabeculectomized eyes with normal IOP after phacoemulsification have not been reported. This case demonstrated that the trabeculectomized eye remains at risk of CRF formation, even if the IOP is normal without hypotony. The importance of a detailed fundus examination in patients with unexplained blurred vision may be necessary after having undergone these procedures. The early recognition of the cause of visual loss may facilitate immediate treatment and may avoid irreversible changes with permanent visual loss.

We report a patient with macular oedema due to type 1 macular telangiectasia responding to intravitreal aflibercept injection. A 51-year-old man was diagnosed with type 1 idiopathic macular telangiectasia (IMT) in the right eye. The macular oedema was refractory to initial treatment with intravitreal bevacizumab and argon laser photocoagulation. The patient was then treated with intravitreal aflibercept injections, following which the macular oedema was completely resolved and his vision was significantly improved. Intravitreal aflibercept injection appears to improve vision and reduce persistent macular oedema secondary to type 1 IMT and demonstrated promising anatomical and visual outcomes.

Background/AimsTo assess the safety and efficacy of argon laser photocoagulation as a new modality for the treatment of presumed trematode-induced granulomatous anterior uveitis (PTGAU) in children.MethodsForty-eight eyes of 48 children with PTGAU with pearl-like nodule(s) in the anterior chamber were included in this prospective non-randomised controlled clinical trial. The patients were divided into two groups: those in Group A (23 eyes) were treated with one session of argon laser applied to the anterior chamber nodules and those in Group B (25 eyes) received medical treatment in the form of topical steroid and cycloplegic eye drops with trans-septal triamcinolone injections. All cases were followed up for 3 months with measurement of visual acuity (VA), assessment of the anterior chamber reaction and measurement of the pearl-like nodule size.ResultsIn Group A, 22 eyes (95.65%) showed regression of the pearl-like nodules with resolution of the anterior chamber reaction (flare and cells) and improvement in visual acuity from 0.52±0.12 to 0.06±0.08 logMAR (p<0.001). Such improvement was maintained within the 3-month follow-up period. In Group B, 23 eyes (92%) showed initial regression of the granulomas, which was maintained in only 14 eyes (56%),with nine eyes experiencing recurrence after 3 months of follow-up.ConclusionArgon laser photocoagulation is a safe and effective novel treatment for PTGAU with pearl-like nodules in the anterior chamber in children. Larger studies with longer follow-up periods are needed to confirm these results.

Branch Vein Occlusion

The Branch Vein Occlusion Study (BVOS) was a randomized, incompletely masked, controlled clinical trial in patients with a branch retinal vein occlusion (BRVO) occurring 3 to 18 months earlier, with best corrected visual acuity of 20/40 or worse from macular edema. The study showed that argon laser grid photocoagulation could improve visual acuity in eyes with BRVO and macular edema reducing visual acuity to 20/40 or worse. After this study, grid photocoagulation of the macula became the standard of care for BRVO with macular edema with foveal involvement and capillary leakage with visual acuity of 20/40 or worse, and it remains the gold standard therapy for perfused macular edema in BRVO. Advantages are that it is proven, widely available, nonsurgical, and of relatively moderate cost.

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.
