Definition

Myopia, or nearsightedness, is a refractive error of the eye. Light rays from a distant object are focused in front of the retina and those from a near object are focused in the retina; therefore distant objects are blurry and near objects are clear (summary by Kaiser et al., 2004). Genetic Heterogeneity of Susceptibility to Myopia MYP2 maps to chromosome 18p. Other myopia loci include MYP1 (310460) on Xq28; MYP3 (603221) on 12q21-q23; MYP5 (608474) on 17q21-q22; MYP6 (608908), caused by mutation in the SCO2 gene (602474) on 22q13; MYP7 (609256) on 11p13; MYP8 (609257) on 3q26; MYP9 (609258) on 4q12; MYP10 (609259) on 8p23; MYP11 (609994) on 4q22-q27; MYP12 (609995) on 2q37.1; MYP13 (300613) on Xq23-q27; MYP14 (610320) on 1p36; MYP15 (612717) on 10q21.1; MYP16 (612554) on 5p15.33-p15.2; MYP17 (formerly MYP4) (608367) on 7p15; MYP18 (255500) on chromosome 14q22-q24; MYP19 (613969) on 5p15.1-p13.3; MYP20 (614166) on 13q12.12; MYP21 (614167), caused by mutation in the ZNF644 gene (614159) on 1p22; MYP22 (615420), caused by mutation in the CCDC111 gene (615421) on 4q35; MYP23 (615431), caused by mutation in the LRPAP1 gene (104225) on 4p16; MYP24 (615946), caused by mutation in the SLC39A5 gene (608730) on 12q13; MYP25 (617238), caused by mutation in the P4HA2 gene (600608) on 5q31; MYP26 (301010), caused by mutation in the ARR3 gene (301770) on Xq13; MYP27 (618827), caused by mutation in the CPSF1 gene (606027) on 8q24; and MYP28 (619781), caused by mutation in the LOXL3 gene (607163) on 2p13.

Retinal detachment

MedGen UID:: 19759
•Concept ID:: C0035305
•: Disease or Syndrome

Primary or spontaneous detachment of the retina occurs due to underlying ocular disease and often involves the vitreous as well as the retina. The precipitating event is formation of a retinal tear or hole, which permits fluid to accumulate under the sensory layers of the retina and creates an intraretinal cleavage that destroys the neurosensory process of visual reception. Vitreoretinal degeneration and tear formation are painless phenomena, and in most cases, significant vitreoretinal pathology is found only after detachment of the retina starts to cause loss of vision or visual field. Without surgical intervention, retinal detachment will almost inevitably lead to total blindness (summary by McNiel and McPherson, 1971).
