What is meant by Brown cataract?

nuclear cataract An opacity affecting the lens nucleus. It can be either congenital or age-related in origin. It frequently leads to an increase in myopia (or decrease in hyperopia). In some cases it reaches such a brown colour that it is called brunescent cataract (or brown cataract).

What causes brown cataract?

Nuclear cataracts form in the middle of the lens and cause the nucleus, or the center, to become yellow or brown. Cortical cataracts are wedge-shaped and form around the edges of the nucleus. Posterior capsular cataracts form faster than the other two types and affect the back of the lens.

What do severe cataracts look like?

1. Clouded, Spotty, and Double Vision. Like we previously stated, a cataract is characterized by cloudy eyes and vision. Because of the cloudiness cataracts cast over the lens of people’s eyes, looking through an eye lens that is diseased with cataracts may seem like looking through a fog.

What is the rarest type of cataract?

Can you see cataracts in the mirror?

At some point, the maturing lens begins to opacify, blocking and scattering the light entering the eye. If left untreated, a cataract will naturally continue to progress. In some cases, the maturing cataract becomes completely white and can be seen in the mirror or by others.

What do early stage cataracts look like?

The symptoms of early-stage cataracts include mild eye blurriness and cloudiness, early sensitivity to light and glare, and an ever-increasing eye strain. Sudden headaches, seeing flashes of lights, sudden vision changes, and double vision could also be symptoms of early to immature stages of cataracts.

What are the problems with cataract surgery?

Posterior capsule opacification (PCO)

  • Intraocular lens dislocation
  • Eye inflammation
  • Light sensitivity
  • Photopsia (perceived flashes of light)
  • Macular edema (swelling of the central retina)
  • Ptosis (droopy eyelid)
  • Ocular hypertension (elevated eye pressure)
  • Why does cataract change color?

    This happens as cataracts have blue light (short wave length light) blocking effect. Given that cataract is a slowly progressive disease, human mind does not perceive the alteration of color and slowly adapts to reduced blue color perception. Hence, after surgery, some patients see ‘blue’ with the eye, as compared to the other non-operated eye.
