Vasculitis associated with the use of an intrauterine device: A case report.

Retinal vasculitis is a complication associated with a local condition or it can be a retinal expression of a systemic inflammatory disorder, which initially may go unnoticed. Drug-associated vasculitis is frequently difficult to identify, because many patients follow treatments with more than one drug and the route of administration varies. A 35-year-old female patient presented with sudden hearing loss, headache and blurred vision that had started two weeks earlier and had become progressively worse. Ophthalmological examination revealed anterior uveitis, bilateral optic disc swelling and retinal vasculitis. The orbito-cerebral MRI, the CT scan and the serological tests were within normal limits. Unable to identify the cause of the retinal vasculitis, the patient's medical history was reviewed. The patient had recently had a gynecological procedure, where a 13.5 mg levonorgestrel intrauterine contraceptive device was implanted. After the device was removed and methylprednisolone treatment started, the patient presented a visible remission of the symptoms and signs. To the best of our knowledge, there is no case of retinal disease and optic disc edema associated with auditory problems caused by an intrauterine device. A proper examination, correlated with a very thorough medical history, could identify rare diseases and associations, in order to provide adequate medical care.

The neuroprotective role of citicoline treatment in glaucoma - 6 months results of a prospective therapeutic trial.

Objectives. Neuroprotective treatment, including citicoline, is a new perspective in glaucoma management, having the role of progression delay. The purpose of the present study was to observe the evolution of the different parameters in patients with glaucoma treated with citicoline. Methods. 22 patients with GPUD were enrolled in the study, and they received oral citicoline in addition to the ocular hypotensive therapy. Investigations were performed at the beginning of the current study, then at 3 months and 6 months, and included, besides full ophthalmologic checkup and IOP determination, optic nerve and RGCs OCT, and visual evoked potentials, pattern and flash. The data we obtained were statistically analyzed with the SPSS (Microsoft) program. Results. The outcomes of the study following VEP wave analysis indicated variations in P100 wave amplitude, but after 6 months period, an increase was found. Also, the P2 wave amplitude recorded statistically insignificant variations. The increase in P2 latency at 6 months was noted as statistically significant. Negative correlations were also met between the thickness of the RGC layer and the P100 latency, but also between the amplitude and the latency of this wave. At 6 months, a positive correlation between the RGC layer and the P100 amplitude was observed. The RNFL thickness at the optical disc had higher values at the 6 months visit, it was statistically significant, and a slight increase in the thickness of the RGC layer between successive visits was noted. These might be an examination artifact because clinically they are not possible. The RNFL thickness showed a positive correlation with the amplitude of P100 and P2 waves. Conclusions. The study of the parameters and their correlations demonstrated that citicoline had positive effects in glaucoma on certain aspects, data confirmed by literature.

Rare ophthalmology diseases.

Rare ocular pathology has an important impact on the quality of life of patients because often the damage is bilateral and, although asymmetric, causes a significant decrease in visual acuity. Because it may be asymptomatic until a relatively late stage, diagnosis is frequently delayed. A general understanding of the disease pathophysiology, diagnosis, and treatment may assist primary care physicians in referring high-risk patients for comprehensive ophthalmological examination and for a more active involvement in their care. Moreover, a significant percentage of these orphan diseases do not have treatment approved by the FDA. The examination and monitoring of patients with rare ophthalmological disorders represents a key component of an ongoing project at the University Emergency Hospital, Bucharest, Romania - Ophthalmology Clinic. Rare disease registries are leading tools for the development of clinical research for rare diseases, improvement of patient access to new diagnostic methods, follow-up and new emerging therapies. As of this moment, the European list of rare diseases includes 53 ophthalmological diseases, which are classified as rare diseases and another 103 systemic diseases with ophthalmological involvement, out of a total of 7000 rare diseases.

Ocular implants-methods of ocular reconstruction following radical surgical interventions.

The main motivation of an ocular-orbital reconstruction after a radical surgical intervention (evisceration, enucleation) is represented by the psychological and socio-economic impact of such interventions on life conditions of patients. The current methods for ocular prosthesis are based on a new concept, which is nanotechnology, and its main objectives represent the reconstruction of the remaining orbital volume, reduction of postoperative complications and maintaining a satisfactory esthetical aspect. This review will discuss the numerous types of ocular implants that have been used throughout history as well as the most recent methods used by ophthalmic surgeons, also taking into consideration the advantages and disadvantages from a cosmetic, functional and short and long term postoperative complications point of view.

Correlations between internal and external ocular factors and macular pigment optical density.

AIM: To assess the relationship between the macular pigment optical density and blue-light issued by computers, glare sensibility, with iris color, age, sex, or refractive errors. MATERIAL AND METHODS: 83 patients (166 eyes) were enrolled in a prospective observational study. They were divided into 2 groups: group 1 (study group) - computer using patients (time spent in front of the computer for minimum 8 hours per day, 5 days per week, 2 years) - 43 patients and group 2 (control group) - 40 patients. The following investigations were conducted in all the selected cases: visual acuity, refraction, biomicroscopy, measurement of the MPOD, glare sensitivity, assessment of eye color. RESULTS: 51.81% of the patients were included in group 1, while the rest, 48.19%, were in group 2. Thus, the MPOD had a mean value of (+/ -SD) 0.42+/ -0.13 (t = -1.08, p = 0.28) in group 1, and 0.44+/ -0.16 on the LE. The results showed a MPOD mean value of 0.51+/ - 0.16 in group 2 and 0.51+/ -0 .16. (t = 0.49, p = 0 .62) on the LE. 55.77% of the patients with light colored iris and 56.14% of those with dark iris had a low MPOD. CONCLUSIONS: The data from our study failed to illustrate a significant correlation between MPOD and blue-light issued by computers. Furthermore, a statistic significant relationship regarding iris color, refractive errors, glare, and MPOD was not observed.

Pseudophakic bullous keratopathy.

Pseudophakic bullous keratopathy is characterized by corneal stromal edema with epithelial and subepithelial bullae due to cell loss and endothelial decompensation through trauma during cataract surgery. Patients present decreased vision, tearing, and pain caused by ruptured epithelial bullae. Cataract affects approximately 20 million people worldwide, and this complication can occur in 1 to 2% of the cataract surgeries. This study reviewed the bullous keratopathy etiopathogenesis and the clinical and surgical treatment available for this corneal disease.
