Investigation of the color discrimination ability using the Farnsworth-Munsell 100-hue test and structural changes by SS-OCT in patients with transfusion-dependent beta-thalassemia.

Aim: This study aimed to examine the color discrimination ability of patients with transfusion-dependent beta-thalassemia (TDβ-T) in detail using the Farnsworth Munsell (FM) 100-hue test and to evaluate structural changes by swept source-optical coherence tomography (SS-OCT).

Material And Methods: This prospective, sectional study included 40 patients (79 eyes) with TDβ-T and 21 controls (42 eyes). The volunteers underwent a detailed ophthalmological examination and SS-OCT (DRI-OCT, Triton) imaging.

Optical coherence tomography angiography findings in transfusion-dependent beta-thalassemia patients with and without splenectomy.

Background: Ocular involvement is common in transfusion-dependent beta-thalassemia (TDβ-T) patients. We aimed to investigate the effect of splenectomy on optical coherence tomography angiography (OCTA) findings in TDβ-T patients.

Methods: The study is a prospective cross-sectional study.

Investigation of relationship between colour discrimination ability and stereoscopic acuity using Farnsworth Munsell 100 hue test and stereo tests.

Objective: To evaluate the effect of colour discrimination ability on the stereoscopic acuity by comparing individuals having congenital colour vision deficiency (CCVD) with healthy individuals.

Design: A comparative study.

Participants: The study included 53 binocular males, of whom 26 (mean age, 36.

Colour vision in juvenile myoclonic epilepsy.

To determine the integrity of colour perception, related to photic sensitivity, in patients with juvenile myoclonic epilepsy. Twenty-four patients with photoparoxysmal response, 27 patients without photoparoxysmal response, and 32 healthy individuals were investigated using the Farnsworth Munsell-100 Hue test to calculate error scores for total colour, blue/yellow, and red/green. No significant differences were observed regarding blue/yellow, red/green or total error score between juvenile myoclonic epilepsy patients with or without photoparoxysmal response.

The effect of splenectomy on complement regulatory proteins in erythrocytes in β-thalassemia major.

Introduction: Hemolysis due to ineffective erythropoiesis is a serious problem β-thalassemia major (β-TM) patients. The role of complement system in the etiopathogenesis of hemolysis observed in β-TM were released. Hemolysis induced by activation of complement system is prevented by complement regulatory proteins.

Color vision testing versus pattern visual evoked potentials and optical coherence tomography parameters in subclinical optic nerve involvement in multiple sclerosis.

Acute idiopathic demyelinating optic neuritis is frequently the initial manifestation of multiple sclerosis (MS). We aimed to discuss the value of color vision testing to detect possible optic nerve involvement in patients with MS who had no history of optic neuritis. We evaluated color vision with Farnsworth-Munsell 100 (FM-100) hue test.

Relation of eye dominancy with color vision discrimination performance ability in normal subjects.

Aim: To evaluate the performance of dominant eye (DE) for color vision discrimination ability among the medical students with normal color vision.

Methods: Total of 50 students studying at Başkent University Faculty of Medicine, including 31 males (62%) and 19 females (38%), with visual acuity of 20/20 and without congenital color vision deficiency (CCVD) evaluated by Ishihara pseudoisochromatic plate test (IPPT) were recruited for this prospective comparative study upon their voluntary participation. DE was determined by the Gündoğan Method.
