    Gene therapy in color vision deficiency: a review

    Color vision deficiency (CVD) is a wide range of complex anomalies affecting the color perception of cones in the retina. In humans, color vision is trichromatic; it is based on three various conal photopigments: L-cones, M-cones and S-cones [ 1 ].

  3. A pathological indicator for dysthyroid optic neuropathy: tritan color vision deficiency

    Thyroid-associated orbitopathy (TAO) is the most common manifestation of Graves’ disease, affecting 25–50% of patients with the condition [ 1 ]. TAO presents as an orbital inflammation leading to an enlargement of the extraocular muscles and …

  4. Evaluation of acquired color vision deficiency in retinal vein occlusion using the Rabin cone contrast test

    Retinal vein occlusion (RVO) is the second most common retinal vascular disorder after diabetic retinopathy [ 1 ]. There are two main types of RVO, branch retinal vein occlusion (BRVO), and central retinal vein occlusion (CRVO). Macular edema (ME) …
