Parry Romberg Syndrome

Parry-Romberg syndrome (PRS) is a rare disorder which causes progressive hemifacial atrophy, with ocular manifestations like hypotony, enophthalmos and corneal edema on the ipsilateral atrophic side. This is a report of a unique case of PRS with contalateral manifestations like ectropion uvea, correctopia and endothelial deposits, along with polymegathism and pleomorphism seen on specular microscopy suggestive of Iridocorneal Endothelial (ICE) Syndrome. ICE syndrome and PRS have not been reported together in any literature so far. This case highlights the importance of a thorough glaucoma workup and corneal examination on the atrophic facial side as well as on the apparently normal side in all cases of PRS.

We report a case of a 42-year-old-woman, who presented to the ophthalmic consultation for decreased visual acuity complaints of blurred vision, altered pupillary shape since few months of her right eye. The clinical examination found a reduced visual acuity to counting fingers in the right eye and 20/20 in the left eye. intraocular pressures was 38 mm Hg OD and 14 mm Hg OS. Slit lamp examination of the right eye found: Corneal edema, iris atrophy with a deformation of the iris architecture and pupillary anomalies, with polycoria (Figure 1). The evaluation of the angle by gonioscopy found areas of broad synechiae anterior to Schwalbe’s line (Figure 2). While the examination of the left eye was normal (Figure 1B). The posterior segment examination was normal in both eyes. Specular microscopy confirmed the presence of unilateral endothelial pleomorphism and polymegathism. In our case of the retained diagnosis was iridocorneal endothelial syndrome

Abstract Background To describe a case of a rare association of bilateral keratoconus and unilateral essential iris atrophy and to conduct a literature review of the current strategies of treatment of the corneal disease and glaucoma in patients with Iridocorneal Endothelial Syndrome (ICE). Case presentation We report a rare association of bilateral keratoconus and unilateral essential iris atrophy in a 38-year-old man. Diagnosis of bilateral keratoconus was confirmed by corneal topography. Slit-lamp examination showed extensive iris atrophy with corectopia and policoria in one eye. Corneal specular microscopy revealed an abnormal endothelium morphology in the same eye with extensive peripheral anterior synechiae and closure of the drainage angle at gonioscopy. Intraocular pressure was 26 mmHg, despite maximal topical therapy. Optic disc examination showed severe glaucomatous cupping. Surgery by glaucoma drainage device implantation was performed. Conclusion Essential iris atrophy is a rare clinical variant of ICE syndrome characterized by profound anatomical alterations of the anterior segment associated with corneal edema and secondary glaucoma. In these patients, selective keratoplasties have replaced penetrating keratoplasty to treat corneal decompensation and glaucoma drainage devices are preferred to conventional trabeculectomy for the treatment of secondary glaucoma.

Purpose: In the present study we evaluate the corneal endothelium using specular microscopy in patients with obstructive sleep apnea syndrome (OSAS). Methods: The study included a total of 100 patients including 35 patients with mild OSAS, 34 patients with moderate OSAS and 31 patients with severe OSAS, and the right eyes of 30 patients as a control group. Patients were examined to exclude the possibility of ocular diseases. Cellular density in the cornea epithelium (cell/mm2), corneal thickness (µ), percentage of hexagonal cells (%) and the coefficient of variation were evaluated using a specular microscope. Results: Corneal thickness was significantly decreased in all OSAS groups when compared to the control group ( p = 0.002), while no significant difference was identified among the OSAS groups. The corneal endothelial cell density, percentage of hexagonal cells and coefficient of variation were significantly different between the OSAS groups and the control group ( p < 0.001). Conclusion: More significant impairments were noted in the corneal endothelium of the patients in the OSAS group than in the control group, and specular microscopy is in valuable in the follow-up and treatment of such patients.

The purpose of this study was to evaluate the effectiveness and safety of a novel buffered riboflavin solution approved for corneal cross-linking (CXL) in progressive keratoconus and secondary corneal ectasia. Following the in vivo preclinical study performed on New Zealand rabbits comparing the novel 0.25% riboflavin solution (Safecross®) containing 1% hydroxypropyl methylcellulose (HPMC) with a 0.25% riboflavin solution containing 0.10% EDTA, accelerated epithelium-off CXL was performed on 10 patients (10 eyes treated, with the contralateral eye used as control) through UV-A at a power setting of 9 mW/cm2 with a total dose of 5.4 J/cm2. Re-epithelialization was evaluated in the postoperative 7 days by fluorescein dye test at biomicroscopy; endothelial cell count and morphology (ECD) were analyzed by specular microscopy at the 1st and 6th month of follow-up and demarcation line depth (DLD) measured by anterior segment optical coherence tomography (AS-OCT) one month after the treatment. We observed complete re-epithelization in all eyes between 72 and 96 h after surgery (88 h on average). ECD and morphology remained unchanged in all eyes. DLD was detected at a mean depth of 362 ± 50 µm, 20% over solutions with equivalent dosage. SafeCross® riboflavin solution chemically-boosted corneal cross-linking seems to optimize CXL oxidative reaction by higher superoxide anion release, improving DLD by a factor of 20%, without adverse events for corneal endothelium.
