Objective: To investigate in detail the exact relationship between Pseudomyopia, also termed accommodative spasm, and psychiatric disorders. Methods: Twenty-one young people between the ages of 12-18 who were diagnosed with pseudomyopia between March 2019 and July 2020 in the ophthalmology eye clinic of a university hospital, Turkey were included in the study. A difference of at least 2.20 D between refractive error measurements before and after cycloplegic drop was accepted as pseudomyopia. Scl-90-r symptom screening scale was applied to each case. Afterwards, each case was evaluated by k-sads-pl-dsm-5-t semi-structured technique according to age. The relationship between psychiatric disorders in cases of pseudomyopia was examined. Results: The average age of patients in the study was 15,4 ± 1,9 (12-18), 13 (61,9%) girl and 8 (38,1%) boy. The mean initial refraction was -4,19D ± 2,48D (-1,75D /-8,50D), and the result refraction was +0,38D ± 0,22D (0,25D / -1,00D). The average amount of accommodation was 4,56D ± 2,59D (2,25D / 9,50D). Following the SCL-90-R screening scale and psychiatric evaluation, five generalized anxiety disorders, three obsessive compulsive disorders, three panic disorders, one social anxiety disorder, one posttraumatic stress disorder, one conversion disorder, one major depressive disorder were diagnosed. As a result, 15 (71,4%) of 21 patients were treated with a psychiatric diagnosis. In addition, a positive correlation (p: 0,010-r: 0,621, p: 0,029-r: 0,546) was detected between anxiety- somatization scores and accommodation amount. Conclusions: It is necessary to request psychiatric consultation in each case of pseudomyopia. Comorbidity of anxiety and depressive disorders is more common in pseudomyopia cases. In addition, as the severity of psychiatric symptoms increases, the amount of accommodation also appears to increase. doi: https://doi.org/10.12669/pjms.37.5.3991 How to cite this:Kara H, Yasar E, Gurlevik U.

Purpose To investigate the effect of oral isotretinoin use on refractive error, axial length, and anteroposterior segment parameters. Materials and methods In this prospective study, 50 eyes of 50 patients using isotretinoin with a diagnosis of acne vulgaris and 50 eyes of 50 healthy control subjects were included. After detailed biomicroscopy, measurements were taken of axial length, lens thickness, central corneal thickness, anterior chamber depth, central retinal thickness, and subfoveal choroidal thickness. The pupils of both eyes were dilated with one drop of cycloplegic drops after refraction measurement. Visual acuity examination was performed with a Snellen chart the next day. The same procedure was repeated at the end of the third and sixth month of drug treatment. Results Forty-seven patients with acne vulgaris and 45 healthy controls met the inclusion criteria and were included in the analysis. The mean ages of the patients and the controls were 21.7 +/- 2.5 years (range, 18-28 years) and 22.6 +/- 2.7 years (range, 19-27 years), respectively. No significant changes were observed in any parameters in the third and sixth month in the control group (p > 0.05). The most important result was significant increases in myopia and axial length in the sixth month of isotretinoin use (p = 0.01, p = 0.04, respectively). There were no significant relationships between increases in myopia and axial length and patients' age, sex, drug dose, and initial refraction (p > 0.05). The changes in spherical equivalent and axial length differed significantly between the drug group and the control group (p = 0.001, p = 0.001, respectively). Conclusions Isotretinoin is one of the important molecules in the aetiology of myopia. Oral isotretinoin treatment may increase myopia and axial length, although not to a clinically significant degree. However, as this was a pilot study, there is a need for further studies with more patients and longer follow-up periods.

Previous studies has shown that dry eye test abnormalities, meibomian gland dysfunction (MGD), may occur in psoriasis. The authors aimed to evaluate the dry eye disease (DED), MGD, in psoriasis patients with meibography which is a current, objective, noninvasive method for patients with meibomian gland diseases, to investigate the relationship between disease severity and ocular involvement. This study included 50 participants with psoriasis and 50 healthy individuals. All subjects were examined by the same dermatologist and referred for ophthalmological examination including meibomian gland obstruction, lid margin alterations assessment, ocular surface disease index assessment, tear film break-up time test, Schirmer test, corneal conjunctival fluorescein staining assessment. Additionally, upper and lower lids were evaluated for meibomian gland loss with meibography. MGD (28%), meibomian gland loss (MGL) (29.5%), upper meiboscore (0.61 ± 0.81), lower meiboscore (0.46 ± 0.61), DED (22%) were significantly higher in the psoriasis group compared with the control group (p = 0.008, p < 0.001, p = 0.027, p = 0.041, p = 0.044, respectively). There was a significant relationship between MGD and psoriasis area severity index (PASI) (p = 0.015, Odds Ratio = 1.211). There was a significant positive relationship between MGL with PASI (p < 0.001, r = 608) and psoriasis duration (p < 0.001, r = 0.547). Smaller study group and inability to detect quality changes of meibum with meibography were limitations of the study. Psoriasis may affect the meibomian gland morphology, may cause structural changes in meibomian glands, and as a result of these may cause MGD and DED. Therefore, ophthalmologists and dermatologists should be aware of this situation and co-evaluate the patients in this respect.
