To quantify retinal thickness in patients with Parkinson disease (PD).Methods: Forty-five eyes of 24 PD patients and 31 eyes of 17 control subjects underwent a comprehensive ophthalmologic examination. We used optical coherence tomography to examine retinal thickness, separately quantifying the inner and outer retinal layers. Intraocular pressure was measured by Goldmann applanation tonometry. Results:The mean (SD) ages of the patients with PD and healthy subjects were 64.0(6.5) years vs 63.5(10.7) years (P=.77). The mean (SD) intraocular pressure was 13.6 (ϩ/−2.7) mm Hg in the PD patients. No difference was found in either the superior or inferior outer retinal layer thickness of PD vs control eyes. The mean (SD) superior inner retinal layer thickness of PD vs control eyes was 88.79 (11.3) µm vs 103.5 (24.3) µm (P=.01), and the mean inferior inner retinal layer thickness was 89.83 (11.1) µm vs 104.0 (23.5) µm (P=.01). Conclusions:The inner retinal layer is significantly thinner in PD patients than in healthy subjects. Idiopathic PD, distinct from glaucoma, needs to be considered in the differential diagnosis of retinal nerve fiber layer thinning.
BackgroundThe purpose of this study was to investigate the most common reasons for urgent ophthalmology consultations in both the emergency room and inpatient settings at a large public hospital served by a busy ophthalmology residency program, and to track patient follow-up rates.MethodsWe reviewed the medical records of all patients evaluated by the ophthalmology consultation service at Kings County Hospital Center from June 2003 to October 2005 using a retrospective hospital-based study design. We categorized emergency room patients and inpatients into traumatic and nontraumatic subgroups, and looked at diagnoses and patient demographics, as well as follow-up patterns for emergency room consultations.ResultsIn total, 743 patients were evaluated; 436 (59%) were emergency room patients and 307 (41%) were inpatients. Consultation for traumatic eye injury was provided for 399 patients (54%), accounting for 284 (65%) of the emergency room consults and 115 (37.5%) of the inpatient consults. The most common reason for inpatient consultation was to rule out ocular manifestations of systemic disease (57 patients, 29.7%), while the most common final diagnosis for trauma inpatient consultation was orbital wall fracture (59 patients, 51.3%). In total, 262 patients (60%) in the emergency room consultation group returned for follow-up care; 162 (57%) of the trauma patients followed up and 100 (66%) of the nontrauma patients followed up.ConclusionThis study provides a comprehensive analysis of the eye conditions and follow-up rates evaluated by the ophthalmology service at Kings County Hospital Center. By evaluating the follow-up patterns of these patients, we may be able to alter patient counseling to increase patient compliance.
