Ophthalmia Nodosa

Purpose: To report the clinical course of ophthalmia nodosa with a retained lenticular seta misdiagnosed and treated as non-infectious posterior uveitis for 7 consecutive years. Methods: Meticulous clinical examination led to discovery of the caterpillar seta embedded in the crystalline lens and the intravitreal setae. Results: Lens-sparing pars plana vitrectomy and removal of free-floating vitreal seta resulted in complete resolution of vitritis and uveitis. Conclusion: Embedded seta within a clear lens may remain sequestered, and may be left untouched under close observation, precluding a clear lens extraction in such patients.

Purpose is to review the pathogenic mechanism for ocular hypertension and glaucoma development after pars plana vitrectomy. Both acute and chronic causes are considered, and special attention is paid to the theories and clinical evidence on the risk of developing Open Angle Glaucoma (OAG) after Pars Plana Vitrectomy (PPV). Most existing scientific literature on the issue agree on the role of ascorbate as an oxygen scavenger within the vitreous chamber. Oxygen tension in the vitreous and anterior chamber is maximum inn proximity of the retinal surface and endothelium, respectively and steeply decreases toward the lens, on both sides, and trabecular meshwork. Vitreous removal and, to a lesser extent, liquefaction, greatly reduces oxygen tension gradient in vitreous chamber while cataract extraction has similar effects on anterior chamber oxygen gradients. Oxygen derivatives originated from the cornea and retina are actively reduced by the vitreous gel and/or the crystalline lens. Vitreous removal and cataract extraction reduce drastically this function. Most reported clinical series confirm this hypothesis although protocol difference and follow-up length greatly impact the reliability of results.

Purpose: To describe a case with an unusual presentation of Propionibacterium acnes ( P acnes) with ultimately a good visual outcome. Methods: A case report with review of approaches to P acnes endophthalmitis. Results: We describe a patient with an unusual presentation of P acnes of panuveitis with white, circular preretinal lesions without intracapsular deposits. Diagnosis was made from cultures from pars plana vitrectomy. Eventually, she was definitively managed with capsulectomy, repositioning of her intraocular lens via sutureless intrascleral fixation, and intravitreal vancomycin injection. Conclusion: This is a report of P acnes endophthalmitis presenting with discrete preretinal lesions where surgical and medical management lead to a complete resolution of uveitis and symptoms after a 3-year follow up where the patient’s final visual acuity was Snellen 20/20 OU.

Pars Plana

Pars plana vitrectomy (PPV) is currently used as an effective method in many posterior segment pathologies. Although the most common indication is retina and vitreous pathologies, PPV is also preferred in some cases associated with lens and glaucoma. In case the crystalline lens or artificial intraocular lens, which is a product of industrial development, falls into the vitreous, it is essential to remove it mostly with the PPV approach. In some types of secondary glaucoma, especially malignant glaucoma, successful results are obtained in terms of visual prognosis and complications with vitreoretinal surgery techniques.

Purpose: To report a case of Staphylococcus epidermidis endophthalmitis following 27-gauge pars plana vitrectomy for symptomatic vitreous floaters. Methods: The clinical course and imaging findings, including fundus optomap, and spectral domain optical coherence tomography of a 24-year-old male patient were documented. Results: The patient, with a preoperative best-corrected visual acuity (BCVA) of 1.0, developed endophthalmitis following 27-gauge pars plana vitrectomy for symptomatic vitreous floaters. After a series of treatments, including emergent vitreous tap and silicone oil injection, antibiotic treatment, and silicone oil removal, the patient regained a BCVA of 0.6. Conclusion: Although rare, the potential risk of endophthalmitis should be explicitly discussed with patients considering surgical intervention for vitreous floaters.

Blunt ocular trauma is the one of the commonest cause of anterior dislocation of the crystalline lens. We present a case who presented with anterior dislocation of the crystalline lens, vitreous prolapse, and acute painful vision loss in left eye following blunt trauma. The patient was managed with antiglaucoma medications, automated anterior vitrectomy, and surgical extraction of dislocated lens with a delayed pars plana vitrectomy and transcleral fixation of crystalline lens.

Purpose: To describe a case of malignant glaucoma following insertion of a Preserflo™ MicroShunt in a patient with primary open angle glaucoma (POAG). Design: Case report. Case: A 46-year-old Caucasian man with medically uncontrolled POAG developed malignant glaucoma 1 day after an uncomplicated insertion of a mitomycin C (MMC) augmented Preserflo MicroShunt (PMS). Results: Initial medical treatment with aqueous suppressants and atropine 1% resulted in temporary resolution of the episode, although partial occlusion of the PMS with iris required a Nd:YAG laser iridotomy to open the inlet of the device. However, the malignant glaucoma recurred 6 days later. Temporary resolution was subsequently achieved with an Nd:YAG laser peripheral irido-zonulo-hyaloidotomy in combination with topical atropine, though a subsequent PMS revision was required due to bleb encapsulation. Unfortunately, the revision procedure was followed 2 days later, by a further recurrence of malignant glaucoma which was eventually resolved by left pars plana vitrectomy (PPV) in combination with clear lens extraction (CLE) and surgical irido-zonulo-hyaloidectomy. Subsequently, the eye remained stable, with a deep anterior chamber (AC), a partially functioning bleb, and an intraocular pressure (IOP) of 14 mmHg on one topical IOP-lowering agent, 8 months after the last procedure. Conclusions: The management of malignant glaucoma after PMS insertion and its subsequent clinical course is described. Apart from the propensity for a small tube such as the PMS to obstruct with iris when the AC is shallow, management is similar to other scenarios in which malignant glaucoma may develop.
