Ocular rosacea causes dry eye and significant meibomian gland loss that can objectively be demonstrated with meibography. The infrared camera of OCT-that is widely found in many ophthalmology departments-might be used to evaluate meibomian gland dysfunction in these individuals.

Vitreoretinal interface changes and vitreoretinal separations and progression of separation can be easily evaluated by OCT. The current study confirms that posterior vitreous detachment occurs commonly soon after cataract surgery.

BackgroundTo determine the temperament and character profile of glaucoma patients.MethodsA total of 234 patients (104 with primary open angle glaucoma, and 130 control subjects without any ocular disease) were selected for this prospective, cross-sectional study. All the participants underwent a comprehensive ophthalmological examination, including the best corrected visual acuity, intraocular pressure measurement, gonioscopy, and visual field analysis. All the participants were given the Turkish version of the Temperament and Character Inventory (TCI). The TCI is a self-reported evaluate, with 240 true/false items measuring four domains of temperament; harm avoidance (HA), persistence (PS), novelty seeking (NS), reward dependence (RD), and three domains of character; self-transcendence (ST), cooperativeness (C), self-directedness (SD).ResultsThe glaucoma patients achieved the higher scores than the controls for the HA and SD dimensions (p < 0.001 and p = 0.033). The glaucoma patients scored lower than the controls for the NS, P and ST dimensions (p < 0.001, p < 0.001 and p = 0.002). There were no differences in the RD and C scores between the patients and the controls (p = 0.944 and p = 0.343). There was no correlation between the duration of illness and the TCI dimensions. Disease severity was positively associated with HA (r = 0,220, p = 0,025) and the anticipatory worry (r = 0.227, p = 0.021) dimension.ConclusionsGlaucoma patients had a different personality profile to healthy individuals. This may affect treatment compliance and is also important when coping with maladaptive patient attitudes.

BACKGROUND:The objective of this study was to identify the effects of weight and size characteristics of posterior segment intraocular foreign bodies (IOFBs) in open globe injuries.

Objective: To present the etiological factors of patients with Retinal Vein Occlusion (RVO) under the age of 50 years. Methods: The study was conducted at Ege University Medicine Faculty Department of Ophthalmology. The clinical records of patients with RVO under the age of 50 seen between January 2014 and March 2018 were analyzed retrospectively. Forty patients comprised the study. Detailed ophthalmologic examination was performed. Past medical history, drug use, thrombophilic features, hyperviscosity syndromes and pathologies that may cause vasculitis were noted. Results: Forty patients, 22 (55%) male and 18 (45%) female, were included. Mean age was 41.6 ± 10.01 years. Mean intraocular pressure and best-corrected visual acuity were 16.8 ± 5.47mmHg and 0.76 ± 0.64 logMAR, respectively. Hyperhomocystenemia (15 patients, 37.5%), Behçet’s disease (three patients, 7.5%), diabetes and/or hypertension (16 patients, 40%), methylenetetrahydrofolate reductase gene mutation (11 patients, 27.5%), prothrombin gene mutation (four patients, 10%) and factor V Leiden mutation (five patients, 12.5%) were present among the patients as etiological factor. Multiple etiological factors were detected in 11 (27.5%) patients. Factor V Leiden mutation and methylenetetrahydrofolate reductase gene mutation were detected in one patient (2.5%) with Behçet’s disease. Four patients with diabetes and/or hypertension also had hyperhomocystenemia and one of them had additionally prothrombin gene mutation. Two patients with methylenetetrahydrofolate reductase gene mutation also had a factor V Leiden mutation and one of them had additionally a prothrombin gene mutation. Three patients with methylenetetrahydrofolate reductase gene mutation also had hyperhomocystenemia and one patient with prothrombin gene mutation also had methylenetetrahydrofolate reductase gene mutation. Conclusions: Etiological factors that might result in RVO in young individuals should be investigated in detail. Targeted therapies may help to prevent development of new RVOs and potential vascular problems in other organs. doi: https://doi.org/10.12669/pjms.35.5.546 How to cite this:Nalcaci S, Degirmenci C, Akkin C, Mentes J.

The purpose of this study was to investigate the interocular symmetry of ultrasonic biometric characteristics and anterior segment measurements between the fellow eyes of hyperopic anisometropes. Forty-two healthy hyperopic anisometropic cases (1 D mean spherical equivalent difference between eyes) without strabismus were recruited. A range of refractive and ultrasonic biometric parameters were measured in both eyes of each subject including keratometry, mean spherical equivalent, anterior chamber depth (ACD), lens thickness, vitreous depth (VD), axial length (AL), and anterior segment parameters (central corneal thickness (CCT), ACD, anterior chamber volume (ACV)) with Pentacam. Mean spherical equivalent anisometropia was 2.66 ± 1.233 (range 1.125 and 6.25) D, and there was a strong correlation between the degree of anisometropia and the interocular difference in AL (r = 0.632, P < 0.001). A total of 61.3 % of the anisometropia was related with AL (50.7 %) and mean keratometry (10.6 %). Every 1 mm change in AL and every 1 D change in mean keratometry caused a total of 2.82 D and 2.14 D refractive difference, respectively. Among Pentacam parameters, ACD was correlated with ACV (r = 0.528; P < 0.001) and AL (r = 0.510; P = 0.001); ACV was correlated with VD (r = 0.358; P = 0.020); and CCT was correlated with ACV (r = 0.510; P = 0.001) and AL (r = 0.318; P = 0.040). Among ultrasonographic measurements, ultrasonic-ACD was correlated with CCT (r = 0.510; P = 0.001) and lens thickness (r = -0.556; P < 0.001), and VD was correlated with AL (r = 0.937, r = 0.877, P< 0.001). The hyperopic and the fellow eyes displayed a high degree of interocular symmetry for the other measured parameters. AL and mean keratometry are the leading causes of hyperopic anisometropia. However, ACD as measured with Pentacam also shows difference in hyperopic anisometropic eyes.

Bilateral acute iris transillumination (BAIT) is a recently defined disease characterized with bilateral acute, severe pigment dispersion of iris and pupil sphincter paralysis. The etiopathogenesis of the disease is unknown, but antibiotics such as moxifloxacin, clarithromycin, viral infections, and fumigation therapies were considered as probable etiologic factors. A 33-year-old female was referred to our clinic for acute iridocyclitis refractory to azathioprine, colchicum and corticosteroid treatments. Ophthalmic examination revealed bilateral pigment dispersion, significant iris transillumination, heavy pigment deposition in iridocorneal angle, and elevated intraocular pressure. Upon systemic evaluation she was found to have bacterial urinary tract infection. BAIT is an important cause of pigment dispersion and clinicians must be vigilant for this condition to avoid unnecessary diagnostic tests and treatment.

All three fixed combinations effectively controlled IOP for 24-h and had a similar effect on diurnal and nocturnal IOP variations.
