Detach Retina/Retinal detachment (RD), defined as the separation of the neurosensory retina from the underlying retinal pigment epithelium (RPE), can cause devastating visual loss. With advances in surgical techniques, the anatomical reattachment rate has greatly increased, especially after repeated surgery [rx, rx]. However, the final visual outcome remains, in many cases, disappointing once the retinal… Continue reading Detach Retina, Causes, Symptoms, Diagnosis, Treatment

Swollen Eyelids or Swollen red eyelid is a common presentation in primary care. An understanding of the anatomy of the orbital region can guide care. Factors that guide diagnosis and urgency of care include the acute vs. subacute onset of symptoms, presence or absence of pain, the identifiable mass within the eyelid vs. diffuse lid… Continue reading Swollen Eyelids, Causes, Symptoms, Diagnosis, Treatment

Corneal Injury is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. The cornea, with the anterior chamber and lens, refracts light, with the cornea accounting for approximately two-thirds of the eye’s total optical power.[1][2] In humans, the refractive power of the cornea is approximately 43 dioptres.[3] The cornea can be reshaped… Continue reading Corneal Injury, Types, Cause, Symptoms, Treatment

Corneal transplantation is one of the most prevalent and successful forms of solid tissue transplantation. Despite favorable outcomes, immune-mediated graft rejection still remains the major cause of corneal allograft failure. While ‘low risk’ graft recipients with uninflamed graft beds enjoy a success rate of approximately 90%, the rejection rates in inflamed graft beds or ‘high… Continue reading Corneal Transplantation, Types, Procedure, Treatment

Color Blindness Causes/Color blindness is the inability to perceive color differences under normal lighting conditions. It is most commonly inherited from mutations on X chromosome and thus, more common in men than women. Prevalence of deficiency in European Caucasians is about 8% in men and about 0.4% in women and between 4% and 6.5% in… Continue reading Color Blindness Causes, Symptoms, Treatment

Nearsightedness Diagnosis/Myopia or nearsightedness, as it is medically termed, is a vision condition in which close objects are seen clearly, but objects farther away appear blurred. Myopia occurs if the eyeball is too long or the cornea, the clear front cover of the eye, has too much curvature. As a result, the light entering the… Continue reading Nearsightedness Diagnosis, Treatment, Complication

Primary Open-Angle Glaucoma/Glaucoma is a chronic, degenerative optic neuropathy that can be distinguished from most other forms of acquired optic neuropathy by the characteristic appearance of the optic nerve. In glaucoma, the neuroretinal rim of the optic nerve becomes progressively thinner, thereby enlarging the optic-nerve cup. This phenomenon is referred to as optic-nerve cupping. Its… Continue reading Primary Open-Angle Glaucoma, Causes, Treatment
